摘　　要：单相接地故障是影响煤矿高压电网安全供电的主要因素之一,随着煤矿供电网络的增大,单相接地电容电流也会增大,因此准确地计算出电网的单相接地电容电流,为电网的安全运行提供可靠的参考数据很有必要。给出一种改进的实用计算方法,该方法简单、准确,具有较好的参考价值。A major factor of affecting the security of high voltage power supply system in coal mine is single-phase ground fault;the single-phase earth capacity current will increase with the power supply network increases,so it is necessary to accurately calculate the single-phase earth capacitive current of power network for the safe operation of power network to provide reliable reference data.An improved practical calculation method is given,it is simple,accurate,and has a good reference value.
