直流系统高频开关电源型充电装置工作性能定期测试

Periodic test on the working performance of high frequency switching power supply type charging device in DC system

高频开关电源型充电装置被广泛应用在直流供电系统中,然而随着使用时间的推移,装置内部的电子元器件会发生老化损坏、参数变化等现象导致装置的稳压、稳流精度等特性指标的变化以及过压、过流、欠压、欠流等保护功能的失效。定期对充电装置的特性指标和保护功能进行测试变得十分重要。本文以艾默生HD22010-3型(整流模块)充电装置为例,使用GDDZ-220V/110V/50A直流电源特性综合测试系统进行测试,通过新模块与使用3年后的模块的测试数据对比,进一步说明定期对高频开关电源型充电装置进行性能参数测试的重要性。

The high frequency switch charging device is widely used in the direct current power supply system.With the passage of service time,the electronic components inside the device will be aged and damaged,and the change of parameters will affect the change of characteristic indexes such as voltage stabilization and current stabilization accuracy of the device,as well as the failure of protection functions such as over-voltage,over-current,under voltage and under current.It is very important to test and change the characteristic index and protection function of the convective electric device regularly.In this paper,Emerson HD22010-3(rectifier module)charging device is taken as an example,GDDZ-220V/110V/50A direct current power supply characteristics comprehensive test system is used to test,through the comparison of the test data of the new module and the module after three years of use,further explains the importance of regular performance parameter test of high-frequency switch type current device.
