摘要(Abstract):

对一起40.5 kV开关柜放电的原因进行了分析,对2种不同结构套管的电场分布进行了仿真,证明不带屏蔽套管周围空气中,电场强度大,均匀性差,更易发生局部放电。对导致开关柜放电的其他因素也进行了总结,提出切实可行的防范措施。
This paper analyzes the reason of discharging in 40.5 kV switch cabinet and simulates the electric field distribution of two bushing with different structures. It is proved that the screen-free bushing has strong electric field strength and poor uniformity in the air, and hence partial discharge can easily happen. The paper also summarizes other factors causing discharge of switch cabinet and summarizes practical and feasible preventive measures.
