摘　　要：以某35kV专线用户为例,分析了相邻线路故障引起专线用户变频器跳闸的原因,从调整继电保护方式以减少母线电压波动和调整变频器参数以增加其对低压的耐受力两方面出发,深入探讨可能采取的措施,并详细阐述了其原理.This paper gives an example of relay protection research for 35kV special line and analyses the reason why the malfunction of vicinage line can cause the special line user＇s inverter trip. From the two aspects, changing the relay protection to improve the electric power quality and adjusting the parameter of the inverter to improve its adaptive ability to low-voltage, this paper discusses the possible measure and gives the expatiation about the principle.
