不间断电源电气性能测试技术

通信电源是整个通信系统的＂心脏＂。交流不间断电源（UPS,Uninterruptible Power Supply）能够在交流输入突然切断时,通过后备电池继续保证高质量的交流供电。为了提高供电质量,保证通信网络的良好运行,必须对UPS电源设备的各种电气参数进行定期测量,以便及时了解设备的运行状况,调整不利于设备运行的参数。文中介绍了不间断电源（UPS）的工作原理,对其主要电气性能测试方法进行了详细论述。

Measurement of Electric Performance for UPS

The power supply is the heart of the communication system.Uninterrupted Power Supply（UPS） can provide AC power of high quality through backup battery,when the power is cut off suddenly.In order to improve the quality of power,electrical parameters of UPS should be periodically measured to make sure that the communication network runs in good condition.So that we can realize the running condition of the equipment in time and regulate the disadvantage parameters of the equipment.This article introduces the working principle of UPS and states particularly the measurements of main electrical performance.
