电气继电保护的常见故障及维修技术

Common Faults and Maintenance Techniques of Electrical Relay Protection

继电保护装置可以保障电气系统正常工作。一旦电气系统发生故障,继电保护装置就能在第一时间锁定故障位置,及时排除故障,避免故障范围进一步扩大。如果继电保护装置出现问题,就会对电气系统造成不利影响,因此,本文仔细分析电气继电保护中存在的故障,并提出有效的维修技术。

Relay protection device can ensure the normal operation of electrical system.Once the system fails,the relay protection device can lock the fault location at the first time,remove the fault in time,and avoid further expansion of the fault scope.If there is a problem of relay protection device,it will have a negative impact on the electrical system.Therefore,this paper carefully analyzed the faults in electrical relay protection,and put forward effective maintenance technology.
