摘要
通过分析高压综合保护器的选择性漏电保护中影响零序电压和零序电流相位关系的各种因素，提出了正确处理移相问题的具体方法，这对于提高煤矿综合继电保护器的性能。
Through the analysis on factors effecting phase relations of zero sequence voltage and current in selective leakage protections of high voltage composite protection device, the paper put forward the correct method solving phase shift problem.It has certain practical significance for improving performance of composite relay protection device in coal mines.
