摘　　要：分析了零序电抗继电器的运行特性，认为用零序电流和相电流的相位来判别零序电抗继电器的同相点，优于用相电压和零序电流的相位进行判别；零序电抗继电器应用于双回线或环网时，不适宜用切换动作方程的方法提高承受过渡电阻的能力。This paper analyzes thoroughly the characteristics of zero sequence reactance relay and reaches two conclusions: firstly, the determination of the equalphase point with the phasor of zero sequence current and phase current is better than the method with the phasor voltage and the zero sequence current; secondly, the approach that switches the tripping equations to improve the tolerance of grounding resistance is not suitable when the zero sequence reactance relay is applied to double circuit lines or ring network.
