摘要
煤矿井下供电系统历来比较重视短路保护、漏电保护和接地保护,并制订了相应的规程或细则,这对保证安全供电是必不可少的。但在研制千伏级供电系统和电气设备时。
In this paper operated overvoltage of power supply system in underground coal mine and its isolation coordination are described theore- tically. The specification of overvoltage and its classification are put forward. Detail analysis has been given to operated overvoltage in 6kV system and low-voltage system and measures to be taken.
