SF6绝缘金属外壳开关操作小电容性电流下暂态过程

Transient in a SF_6 insulated Metalenclosed Switchgear under Operation of a Small Capacitive Current

本文主要讨论SF_■绝缘金属外壳开关在操作小电容性电流下的暂态过程。从现场实测波形入手,建立等效电路,进行理论分析,确定振荡频率大小,并利用EMTP模拟计算,将其与实测结果进行比较,结果是可行的。

For accomplishing the target of this research equivalent circuits are set up according tothe measured waveforms in situ. Their theoretical analysis is conducted and the magnitude of is determined. The results of simulated calculations by the use of EMTP are compared with the pratically measured ones.
