摘要

GIS隔离开关在操作过程中会产生VFTO

对设备的安全稳定运行构成威胁

因此

研究隔离开关操作过程中VFTO的抑制措施具有重要意义。文中首先开展了隔离开关操作顺序对VFTO影响的理论分析

以某抽水蓄能500kVGIS由于VFTO引起的故障案例

通过仿真计算分析了优化操作顺序降低VFTO的效果。最后

对该措施的进一步推广应用进行了展望。

Abstract

The GIS disconnector will generate VFTO during operation

which poses a threat to the safe and stable op-eration of GIS equipment. Therefore

it is of great significance to study measures to suppress VFTO during the opera-tion of the disconnector. Firstly

the impact of the operation sequence of the disconnector on VFTO was analyzed theo-retically. Based on a 500 k V GIS failure case caused by VFTO

the effect of optimizing the operation sequence to sup-press VFTO was analyzed by simulation calculation. Finally

the further promotion and application of this measurewere prospected.
