摘要
井下高压电网产生的电容电流,是煤矿生产中普遍存在的问题。本文叙述了电容电流产生的危害,提出了电容电流的限制方法。井下的电容电流,因考虑到安全,不能直接测试,故采用间接测试方法。对于采用附加电容的间接测试方法,推导出一个简单的计算公式,这在实际工作中是很方便的。
The capacitance current induced by underground high tension network is a common problem existing in coal mines.This paper described the risks of capacitance current and proposed a method for limiting the current. The underground capacitance current can only be measured indirectly,not directly for safety purposes.This paper derived a simple formula for indirect measurement of the capacitance current by an additional capacitance which is convenient in practical work.
