摘要
电流互感器作为电流变换设备在电力系统生产运行中起着非常重要的作用,它为测量仪表、保护装置的正常运行提供电源.但电流互感器励磁特性差和二次回路误接线、断线、分流等问题严重影响电网系统的安全稳定运行.为了解决上述问题,根据生产运行中的实际经验,对上述问题产生的原因进行了分析,并提出了预防处理措施.
The current transformer as current transformation equipment plays a very important role in the operation of power system. It provides power supply for the normal operation of protection devices and measuring meters, but some problems such as poor excitation characteristics of the current transformer, secondary loop false wiring, disconnection, shunt seriously have been affecting the safe and stable operation of power grid system, and disturbing the production, operation and maintainer. In order to avoid the above problems appearing in the future work and deal with these problems properly, the causes of these problems are analyzed and the preventive measures are put forward according to the actual experience.
