矿用低压电器通断试验对电力系统的影响分析

Mine Low Voltage Apparatus Making and Breaking Test Impact Analysis of Power System

阐述了煤矿用低压电器在发生短路时不能正常分断电路,对安全生产造成的危害。利用计算和软件仿真的方法对通断试验过程中系统母线电压波形的变化情况进行了影响分析。根据分析结果得到,在矿用低压电器通断试验正常运行时,对电力系统的影响符合国家标准相关要求。

Expounds the mine low voltage apparatus in short circuit can not be normal breaking circuit,the hazards caused by the production safety. Using the method of calculation and simulation software for making and breaking test system bus voltage waveform changes in the process of the impact analysis. According to analysis results, the making and breaking test run normally, the impact on power system conforms to the national standard requirements.
