摘要
电网继电保护中一个重要的组成部分便是变电站220 kV线路保护,其是输电线路能够安全稳定运行的保障,直接影响着线路故障的切除效果与供电质量,而且由于常年暴露在空气中,很容易受到外界因素的侵害,所以很容易出现各种输电事故,出现事故时可能会对电网造成很大损害,因此有必要进行合理的运行维护.
An important component of power grid relay protection is 220 kV line protection in substation.It is the guarantee of safe and stable operation of transmission lines.It directly affects the removal effect of line faults and the quality of power supply.Moreover,it is vulnerable to external factors because it is exposed to air all the year round.It is easy to cause various transmission accidents,which may cause great harm to the power grid,so it is necessary to carry out reasonable timing operation and maintenance.
