煤矿用低压电器设备通断试验电源需求分析

Analysis of Make-and-Break Test Power Supply of Low Voltage Electrical Apparatus for Coal Mine

从标准对通断试验容量和电源的要求入手,对额定电流630A以下电气设备通断试验所需的供电电源进行分析,进行不同形式下的电压波动计算和最大试验电流的计算,为煤矿用低压电器试验室建设中试验电源问题的解决提供参考。

Starting with the stardands to make-and-break test capacity and power supply requrements, the power supply source of the make and break test of electrical apparatus equipment under rated current of 630A is analyzed. The voltage undulation ealeulation and maximum test current calculation under different conditions are carried out. It provides referemes for the test power source problems of low voltage electrical apparatus laboratory under construction for the coal mine.
