GIS disconnector closing operation is generally achieved through the installation in the side or middlephase of the operation mechanism driven inter phase connecting rod movement

alternating transmission mechanismonce an exception occurs

affect other apart from the switch body switching operations

and even cause GIS insula-tion fault. According to together GIS disconnector cause of insulation defects in GIS case because of the failure of thetransmission mechanism

root cause failure analysis

and puts forward the solving measures

and improve the levelof safe operation of the GIS and grid

and has good application value.
