科士达UPS电源的基本应用原理

现在科士达UPS电源在计算机的外围设备中已经从一个不是很受重视的角色迅速演变成为互联网的关键设备及电子商务的保卫者。UPS电源是企业重要的供电保障设备，传统的维护管理包括：①日常巡检外观，定期更换电池、滤波电容、风机等易损件，大修时做电池活化等;②改造或采用换代设备，使用高级工具测试电池性能。这种管理方式企业投入成本高，维护人员工作量大，不易实时掌握设备运行状态和关键数据，设备事故预防能力低。实施在线维护管理可避免传统方式的不足之处，获得良好效益。

科士达UPS电源的基本应用原理

从基本应用原理上讲，科士达UPS电源是一种含有储能装置，以逆变器为主要元件，稳压稳频输出的电源保护设备。主要由整流器、蓄电池、逆变器和静态开关等几部分组成。

1)整流器：整流器是一个整流装置，简单的说就是将交流(AC)转化为直流(DC)的装置。它有两个主要功能：第一，将交流电(AC)变成直流电(DC)，经滤波后供给负载，或者供给逆变器;第二，给蓄电池提供充电电压。因此，它同时又起到一个充电器的作用;

2)蓄电池：蓄电池是科士达UPS电源用来作为储存电能的装置，它由若干个电池串联而成，其容量大小决定了其维持放电(供电)的时间。其主要功能是：1当市电正常时，将电能转换成化学能储存在电池内部。2当市电故障时，将化学能转换成电能提供给逆变器或负载;

3)逆变器：通俗的讲，逆变器是一种将直流电(DC)转化为交流电(AC)的装置。它由逆变桥、控制逻辑和滤波电路组成;

4)静态开关：静态开关又称静止开关，它是一种无触点开关，是用两个可控硅(SCR)反向并联组成的一种交流开关，其闭合和断开由逻辑控制器控制。分为转换型和并机型两种。转换型开关主要用于两路电源供电的系统，其作用是实现从一路到另一路的自动切换;并机型开关主要用于并联逆变器与市电或多台逆变器。

Now the Corstal UPS power supply in the peripheral equipment of the computer has rapidly evolved from a less valued role to the key equipment of the Internet and the defender of e-commerce. UPS power supply is an important power supply equipment for enterprises. Traditional maintenance and management includes: 1) daily inspection of appearance, regular replacement of vulnerable parts such as batteries, filter capacitors, fans, battery activation during overhaul; 2) modification or use of replacement equipment, using advanced tools to test battery performance. This kind of management mode is characterized by high investment cost, heavy workload of maintenance personnel, difficulty in grasping real-time operation status and key data of equipment, and low ability of preventing equipment accidents. The implementation of online maintenance management can avoid the shortcomings of traditional methods and obtain good benefits.
Basic Application Principle of Corstal UPS Power Supply
From the basic principle of application, Corstal UPS power supply is a kind of power protection equipment with energy storage device, inverter as the main component, stable voltage and frequency output. It mainly consists of rectifier, battery, inverter and static switch.
1) Rectifier: Rectifier is a rectifier device, that is to say, converting AC to DC. It has two main functions: firstly, AC is transformed into DC, which is filtered to supply load or inverter; secondly, it provides charging voltage for storage battery. Therefore, it also acts as a charger.
2) Battery: Battery is a device used by Kosta UPS power supply to store electric energy. It is made up of several batteries in series. Its capacity determines the time of maintaining discharge (power supply). Its main functions are as follows: 1. When the municipal electricity is normal, the electric energy is converted into chemical energy and stored in the battery. When the power failure occurs, the chemical energy is converted into electrical energy and supplied to the inverter or load.
3) Inverter: Generally speaking, the inverter is a device that converts DC into AC. It consists of inverter bridge, control logic and filter circuit.
4) Static switch: Static switch, also known as static switch, is a contactless switch. It is an AC switch composed of two SCR in reverse parallel. Its closure and disconnection are controlled by a logic controller. It can be divided into two types: conversion type and parallel type. Conversion switch is mainly used in two-way power supply system. Its function is to realize automatic switching from one way to another. Parallel switch is mainly used for parallel inverters and municipal or multi-inverters.

科士达UPS电源的电池管理

电池是科士达UPS电源的重要组成部分，在UPS的诸多故障中，有很大比例是由于电池问题引起的，电池性能的好坏直接影响到系统的可靠性。为了保证电池的服务寿命，除了维持正常温度和日常的维护外，电池的自动管理是至关重要的因素。

科士达UPS电源对电池自动管理包括自动均浮充转换控制、电池预告警关机、定期自动维护、手动电池自检等多项可提高电池使用寿命的先进功能，同时还具备电池故障检测、电池放电后备时间预测及电池特征曲线管理。

自动均、浮充转换

电池充电过程能自动根据电池电流实现均充、浮充自动转换，设定的均充转浮充判据为：I≤0.01C。

In principle, Corstal UPS power supply is a kind of power electronic equipment which integrates digital and analog circuits, automatic control inverters and maintenance-free energy storage devices.
In terms of function, UPS can effectively purify the city electricity when the city electricity is abnormal. It can also supply power to computer and other equipment for a certain period of time when the city electricity is suddenly interrupted, so that you can have enough time to deal with it.
In terms of use, with the advent of the information society, Kosta UPS power supply is widely used in all aspects of information acquisition, transmission, processing, storage and application. Its importance is increasing with the increasing importance of information application.
1. Costa UPS Daily Inspection Project:
The main contents include: checking the control panel, confirming that all the indicators are normal, all the indicative parameters are normal, and there is no alarm on the panel; checking whether there is obvious high temperature and abnormal noise; making sure that the ventilation grate is not blocked; adjusting the measured parameters, and observing whether there is any discrepancy with the normal value.
2. Costa UPS Power Weekly Inspection Project:
The main contents of weekly inspection are: measuring and recording battery charging voltage, battery charging current, UPS three-phase output voltage, UPS output line current. If the measured values are significantly different from those before, the magnitude, type and location of the new load should be recorded.
Monthly, Quarterly and Annual Maintenance Projects for UPS Power Supply in Costa Rica:
Battery Management of Corstal UPS Power Supply
Battery is an important part of Kosta UPS power supply. A large proportion of UPS faults are caused by battery problems. The performance of battery directly affects the reliability of the system. In order to ensure the service life of batteries, besides maintaining normal temperature and daily maintenance, the automatic management of batteries is a crucial factor.
The automatic battery management of COSTAR UPS power supply includes advanced functions such as automatic floating charge conversion control, battery warning shutdown, periodic automatic maintenance, manual battery self-inspection and so on, which can improve the service life of batteries. It also has the functions of battery fault detection, prediction of battery discharge backup time and management of battery characteristic curve.
Automatic Average and Floating Conversion
Battery charging process can automatically realize uniform charge and float charge automatic conversion according to battery current. The set criterion of uniform charge and float charge is: I < 0.01C.

2、电池浮充电压温度补偿：(以2V电池为例)

电池在浮充状态下，浮充电压可以根据温度进行补偿，温度补偿以20℃为中心点，在10℃-40℃内全补偿，计算公式：

温度T>40，T=40;若T<10，T=10

电池平均单体电压应调节为：V=V0+(20-T)×0.003

其中，V0为电池厂家给定的在20℃下的单体浮充电压，可以根据不同电池在初次上电时进行设置，默认为2.23V。对均充电压不补偿，默认的单体均充电压为2.35V。

3、均充限时：

如果连续12小时处于均充状态，控制系统将强制转浮充状态，此设置的条件是均充时间达到设定值时，自动转为转浮充状态。

4、放电管理：

设置电池放电的截止电压为每单体电池1.8V，实际截止电压会随电池老化程度不同而在此值附近向下浮动，截止电压为每单体电池1.8V的选取，已经考虑到了大功率放电情况下电池容量的衰减。

科士达UPS电源作为应急电源为企业提供重要的供电保障，它可以保障计算机系统在停电之后继续工作一段时间以使用户能够紧急存盘，使用户不致因停电而影响工作或丢失数据。针对中国电网环境和网络监控及网络系统、医疗系统等对电源的可靠性要求，克服中、大型计算机网络系统集中供电所造成的供电电网环境日益恶劣的问题，以全新的数字技术研制出的第三代工频纯在线式智能型UPS电源。

12、科士达UPS电源应使用开放式电池架，以利于蓄电池的运行及维护。

Temperature Compensation of Battery Floating Charging Voltage: (Take 2V Battery as an Example)
When the battery is in the state of floating charge, the floating charge voltage can be compensated according to the temperature. The temperature compensation is centered at 20 C and fully compensated in the range of 10 - 40 C. The calculation formula is as follows:
Temperature T > 40, T = 40; If T < 10, T = 10
The average cell voltage should be adjusted to V=V0+(20-T)*0.003.
Among them, V0 is given by battery manufacturer as the floating charge voltage of single cell at 20 C, which can be set according to different batteries when they are first powered on. The default is 2.23V. The default unit charge voltage is 2.35V without compensation.
3. Equal time limit:
If the system is in the state of equal charge for 12 consecutive hours, the control system will be forced to transfer to the state of floating charge. The condition of this setting is that when the equal charge time reaches the set value, it will automatically change to the state of floating charge.
4. Discharge management:
Setting the cut-off voltage of battery discharge to 1.8V for each cell, the actual cut-off voltage will fluctuate downwards near this value depending on the aging degree of the cell. The cut-off voltage is 1.8V for each cell. The decay of battery capacity under high power discharge has been taken into account.
Corstal UPS power supply as an emergency power supply provides an important power supply guarantee for enterprises. It can ensure that the computer system continues to work for a period of time after the power outage so that users can save emergency records, so that users do not affect their work or lose data due to power outage.

In the power supply of oil engine, special attention should be paid to avoid this situation.
12. Kosta UPS power supply should use open battery rack to facilitate the operation and maintenance of batteries.

问题一：有市电时科士达UPS电源输出正常，而无市电时蜂鸣器长鸣，无输出。

故障分析:从现象判断为蓄电池和逆变器部分故障，可按以下程序检查:

1.检查蓄电池电压，看蓄电池是否充电不足，若蓄电池充电不足，则要检查是蓄电池本身的故障还是充电电路故障;

2.若蓄电池工作电压正常，检查逆变器驱动电路工作是否正常，若驱动电路输出正常，说明逆变器损坏;

3.若逆变器驱动电路工作不正常，则检查波形产生电路有无PWM控制信号输出，若有控制信号输出，说明故障在逆变器驱动电路;

4.若波形产生电路无PWM控制信号输出，则检查其输出是否因保护电路工作而封锁，若有则查明保护原因;

5.若保护电路没有工作且工作电压正常，而波形产生电路无PWM波形输出则说明波形产生电路损坏。

6.上述排故顺序也可倒过来进行，有时能更快发现故障。

问题二：逆变器功率级一对功放晶体管损坏，更换同型号晶体管后，运行一段时间又烧坏的原因是电流过大，而引起电流过大的原因有:

1.过流保护失效。当逆变器输出发生过电流时，过流保护电路不起作用;

2.脉宽调制(PWM)组件故障，输出的两路互补波形不对称，一个导通时间长，而另一个导通时间短，使两臂工作不平衡，甚至两臂同时导通，造成两管损坏;

3.功率管参数相差较大，此时即使输入对称波形，输出也会不对称，该波形经输出变压器，造成偏磁，即磁通不平衡，积累下去导致变压器饱和而电流骤增，烧坏功率管，而一只烧坏，另一只也随之烧坏。

问题三：蓄电池电压偏低，但开机充电十多小时，蓄电池电压仍充不上去。

故障分析:从现象判断为蓄电池或充电电路故障，可按以下步骤检查:

1.检查充电电路输入输出电压是否正常;

2.若充电电路输入正常，输出不正常，断开蓄电池再测，若仍不正常则为充电电路故障;

3.若断开蓄电池后充电电路输入、输出均正常，则说明蓄电池已因长期未充电、过放或已到寿命期等原因而损坏。

问题四：科士达UPS电源开机后，面板上无任何显示，UPS电源不工作。

故障分析:从故障现象判断，其故障在市电输入、蓄电池及市电检测部分及蓄电池电压检测回路:

1.检查市电输入保险丝是否烧毁;

2.若市电输入保险丝完好，检查蓄电池保险是否烧毁，因为某些UPS当自检不到蓄电池电压时，会将UPS的所有输出及显示关闭;

3.若蓄电池保险完好，检查市电检测电路工作是否正常，若市电检测电路工作不正常且UPS不具备无市电启动功能时，UPS同样会关闭所有输出及显示。

4.若市检测电路工作正常，再检查蓄电池电压检测电路是否正常。

问题五：在市电供电正常时开启科士达UPS电源，逆变器工作指示灯闪烁，蜂鸣器发出间断叫声，UPS电源只能工作在逆变状态，不能转换到市电工作状态。

1.市电输入保险丝是否损坏;

2.若市电输入保险丝完好，检查市电整流滤波电路输出是否正常;

3.若市电整流滤波电路输出正常，检查市电检测电路是否正常;

4.若市电检测电路正常，再检查逆变供电向市电供电转换控制输出是否正常。

问题六：一台后备科士达UPS电源有市电时工作正常，无市电时逆变器有输出，但输出电压偏低，同时变压器发出较大的噪音。

故障分析:逆变器有输出说明末级驱动电路基本正常，变压器有噪音说明推挽电路的两臂工作不对称，检测步骤如下:

1.检查功率是否正常;

2.若功率正常，再检查脉宽输出电路输出信号是否正常;

3.若脉宽输出电路输出正常，再检查驱动电路的输出是否正常。

问题七：在接入市电的情况下，每次打开UPS不间断电源，便听到继电器反复的动作声，UPS电源面板电池电压过低指示灯长亮且蜂鸣器长鸣。

1.根据上述故障现象可以判断:该故障是由蓄电池电压过低，从而导致UPS启动不成功而造成的。拆下蓄电池，先进行均衡充电(所有蓄电池并联进行充电)，若仍不成功，则只有更换蓄电池。

问题八：科士达UPS电源只能由市电供电而不能转为逆变供电。

故障分析:不能进行市电向逆变供电转换，说明市电向逆变供电转换部分出现故障，要重点检测:

1.蓄电池电压是否过低，蓄电池保险丝是否完好;

2.若蓄电池部分正常，检查蓄电池电压检测电路是否正常;

3.若蓄电池电压检测电路正常，再检查市电向逆变供电转换控制输出是否正常。

科士达UPS电源是针对中国电网环境和网络监控及网络系统、医疗系统等对电源的可靠性要求，克服中、大型计算机网络系统集中供电所造成的供电电网环境日益恶劣的问题，以全新的数字技术研制出的第三代工频纯在线式智能型UPS。直流电源，是维持电路中形成稳恒电流的装置。如干电池、蓄电池、直流发电机等。

一、安全第一

每次进行电源维护时，切记生命和身体安全应胜过一切。当处理电源设备时，可能哪怕一个小小的操作失误也会造成严重伤害。因此，当处理科士达UPS电源(或数据中心的任何电力系统)时，确保安全是首要考虑的问题：包括遵守设备制造商的建议，注重设施特殊的细节和标准的安全指引。如果对于UPS系统的某些方面不熟悉，或不知道如何对其进行维护，请找专业人士寻求帮助。即使了解数据中心的UPS系统，仍然有必要寻求相应的外界援助，以便在涉及到某些潜在问题时能有头脑冷静的人给予帮助，使其不会受压力困扰。

二、坚持定期维护

数据中心的预防性维修不应该成为工作人员心血来潮的事情，尤其是考虑到其潜在的停机时间成本。对于数据中心的UPS系统以及其他系统而言，应定期进行维护(以年、半年或任何时间框架为单位)，并坚持贯彻这一维护计划。这包括一份书面的(纸质或电子版)备案清单，记录好下一次维护活动和上一次维护的具体时间。

三、做好详细记录

除了安排好定期的维护计划，数据中心也应该有一份详细的维修记录(例如，清洗、修理或更换某些部件的记录)，以及在在检查过程中，发现的相关设备的具体状况。而当工作人员需要向数据中心的管理人员汇报维护成本或每次停机时间所造成的成本损失时，进行成本跟踪也是非常有益的。一份详细的任务清单，如检查电池腐蚀情况，寻找过量扭矩的连接导线等，有助于维持一个有秩序的方法。而当在进行设备更换、不定期的维修、UPS故障排除规划时，所有这些文档都可以提供帮助。除了做好记录之外，请务必确保这些文档始终放在一个方便得到且大家都知道的位置。

四、执行定期检查

上述三点建议适用于数据中心的几乎任何一部分：无论怎样的数据中心环境，加强安全、调度维护和保持良好的记录都是很好的做法。然而，对于UPS系统，需要有工作人员定期进行某些任务(这些工作人员应该熟悉UPS操作的基本知识)。这些重要的UPS维护工作包括以下几个方面：

1、围绕科士达UPS电源和电池(或其他能量存储)设备进行的障碍物和相关冷却设备方面的检查。

2、确保没有发生运行异常或UPS控制面板没有发出任何类似于过载或电池电量即将耗尽的警报。

3、注意查看电池腐蚀或其它缺陷的迹象。针对那些特定设备，咨询制造商的指导方针和建议。在某些情况下，应该严格履行设备制造商的维护建议。

五、认识到科士达UPS电源组件发生运行失败是可能的

这似乎是显而易见的：任何具有有限故障概率的设备，最终都会发生运行失败的状况。有报告指出：“关键的UPS部件，如电池和电容器不可能始终保持正常使用状态。”所以，即使供电方提供了完美的动力，UPS机房是完全干净的，并且UPS设备是在适当的温度理想情况下运行的，相关组件仍然会发生运行失败的状况。正因为如此，才需要对UPS系统进行维护。

六、确保知道当需要相关服务或不定期的维护时，向谁求助

有时，在日常检查的过程中，就会发现某些问题，而这些问题不能等到下次维护的时候才解决。在发生这些情况的时候，需要确保知道联系谁能够帮助搞定，这样可以节省大量的时间和精力。这意味着数据中心必须确定一家或几家固定的服务提供商，在需要时提供帮助。这些供应商与提供定期维护的供应商可以是同一家，也可以不是同一家。

七、进行任务分配

“你是不是应该上周就进行检查?”“不，我觉得应该是你检查的。”为了避免这种责任不明晰的混乱，请务必确保安排合适的专门人员负责UPS维护任务。哪位工作人员需要负责每周检查设备?哪位工作人员负责联系服务供应商，安排年度维护计划(或者调整维护时间表)?特定的任务可能有不同的负责人，但是要确保知道谁负责UPS系统。

许多科士达UPS电源维护事项最好留给那些熟悉UPS的人员。再次强调，安全是至关重要的：一个UPS系统中的电压的危险性可能出现人身伤亡，所以最好聘请专业人士进行，而不要冒险操作。预防性维护是数据中心的所有工作的关键，所以很多诀窍可以广泛地应用，但UPS系统需要特别关注，因为它在短期内需要稳定的电力以提供给IT设备。通过执行定期的维修计划，可以很容易地防止由于电池电量耗尽、电容器故障、或空气过滤器堵塞，甚至过时的固件焊接继电器造成的停机事件。工作人员只需要经过深思熟虑的执行上述几大步骤，采取预防性的维护程序，就可以帮助其数据中心免去许多麻烦。

Corstal UPS power supply aims at the reliability requirements of China's power grid environment, network monitoring and network system, medical system and so on. It overcomes the increasingly harsh environment of power supply network caused by centralized power supply of medium and large computer network systems, and develops the third generation of power frequency pure on-line intelligent UPS with brand-new digital technology. DC power supply is a device to maintain a steady current in the circuit. Such as dry batteries, storage batteries, DC generators, etc.
Safety First
Every time power supply is maintained, remember that life and physical safety are better than everything else. When dealing with power supply equipment, even a small misoperation may cause serious damage. Therefore, when dealing with Kosta UPS power supply (or any power system in the data center), ensuring security is a top priority: it includes following the recommendations of the equipment manufacturer and paying attention to the specific details of the facility and the safety guidelines of the standard. If you are not familiar with some aspects of UPS system, or do not know how to maintain it, please seek professional help. Even with an understanding of UPS systems in data centers, it is still necessary to seek appropriate external assistance so that cool-headed people can help to avoid stress when it comes to some potential problems.
2. Insist on regular maintenance
Preventive maintenance of data centers should not be a whim for staff, especially considering their potential downtime costs. For UPS systems and other systems in data centers, they should be maintained regularly (in terms of annual, semi-annual or any time frame) and adhere to this maintenance plan. This includes a written (paper or electronic) record list of the next maintenance activity and the specific time of the last maintenance.
3. Make detailed records
In addition to arranging regular maintenance plans, the data center should also have a detailed maintenance record (for example, records of cleaning, repairing or replacing certain components) and the specific condition of the relevant equipment found during the inspection process. When staff need to report maintenance costs or cost losses caused by each downtime to data center managers, cost tracking is also very helpful. A detailed list of tasks, such as checking battery corrosion and looking for excessive torques to connect wires, can help maintain an orderly approach. All these documents can be helpful in equipment replacement, irregular maintenance, UPS troubleshooting planning. In addition to keeping records, make sure that these documents are always in a convenient and well-known location.
IV. Implementing Periodic Inspection
These three suggestions apply to almost any part of a data center: no matter what the data center environment is, it is good practice to enhance security, schedule maintenance and maintain good records. However, for UPS systems, there is a need for staff to perform certain tasks on a regular basis (these staff should be familiar with the basic knowledge of UPS operations). These important UPS maintenance tasks include the following aspects:
1. Inspection of obstacles and related cooling equipment around Corstal UPS power supply and battery (or other energy storage) equipment.
2. Ensure that there is no abnormal operation or that the UPS control panel does not issue any alarm similar to overload or imminent battery depletion.
3. Look for signs of battery corrosion or other defects. Consult the manufacturer's guidelines and recommendations for specific equipment. In some cases, the maintenance recommendations of equipment manufacturers should be strictly implemented.
5. Recognizing that it is possible for Kosta UPS power supply components to fail in operation
It seems obvious that any equipment with limited failure probability will eventually fail. It has been reported that "critical UPS components, such as batteries and capacitors, cannot always be in normal use." Therefore, even if the power supplier provides perfect power, the UPS room is completely clean, and the UPS equipment is running at an ideal temperature, the relevant components will still fail. Because of this, UPS system needs to be maintained.
6. Make sure you know who to turn to when you need relevant services or irregular maintenance
Sometimes, in the process of routine inspection, some problems will be found, and these problems can not be solved until the next maintenance time. When these situations occur, you need to ensure that you know who you can contact to help with them, which saves a lot of time and effort. This means that the data center must identify one or more fixed service providers to help when needed. These suppliers may or may not be the same as the supplier providing regular maintenance.
VII. Task Allocation
"Should you check it last week?" "No, I think it should be you." To avoid this confusion of unclear responsibilities, it is important to ensure that appropriate specialists are assigned to the UPS maintenance tasks. Which staff member is responsible for weekly inspection of equipment? Which staff member is responsible for contacting service providers and arranging annual maintenance plans (or adjusting maintenance schedules)? There may be different leaders for specific tasks, but make sure you know who is responsible for UPS systems.
Many COSTAR UPS power maintenance matters are best left to those familiar with UPS. Again, safety is crucial: the danger of voltage in an UPS system may cause personal casualties, so it's better to hire professionals instead of risky operations.  Preventive maintenance
