Problems and Solutions of the GW16 Type Isolation Switch in Operation

摘要

GW16 type isolation switch of outdoor high voltage system is the commonly used power distribution equipment in 220 kV power system. And it is widely used in the substations that maintained by the EHV power transmission company of Hunan province. It is mainly composed of a static contact assembly, main switch system, the knife blade, rotation of the insulator and the support insulator, a base assembly and transmission system, operating mechanism. It has the advantages of simple structure, convenient installation and operation, but in the operation also exists some problems, this paper in view of the problems proposed feasible solutions.
