摘要

混合型气体绝缘组合电器（hybrid-gas insulated switchgear

HGIS）在运行过程中

发生三相电流不平衡。为分析问题产生的原因

对HGIS进行了一系列试验

并返厂进行解体检查。结果表明:SF6气体分解物中SO2体积分数严重超标

C相回路接触电阻严重增大

C相分合闸时间测试无信号

三工位线隔离开关触头严重烧损。分析表明触头烧蚀是由设计缺陷、安装工艺不良等多个因素引起。对同类型的设备进行排查

发现多起类似问题。针对该类问题

建议厂家在设计应予以改进

并严格管制安装工艺

同时对已运行设备应加强在线监测

尽量避免使用三工位线隔离开关进行线路接地。

Abstract

Three-phase current unbalance of hybrid-gas insulated switchgear（HGIS） will occur in operation.In order to analyze the reasons for the problem

a series of tests and factory disintegration inspection for HGIS are carried out. Results shows that SO2 concentration in SF6 gas decomposition severely exceeds the specified level. C-phase loop contact resistance increases seriously

and no signal is detected in C-phase switching time test. Meanwhile

three-station line switch contact has damaged for ablation. Analysis shows that the contact erosion is caused by factors such as design defects

unqualified installation etc..Investigations for the same type of HGIS are carried out

and several similar problems are found. Aiming at these problems

it is suggested that manufacture should improve in the design and installation process.At the same time

it should strengthen the on-line monitoring of the operation HGIS

and try to avoid using three-station line switch for line grounding.
