Leakage Detecting Methods of GIS and Breaker Air-pressure System
Lei Zhang · Jiangsu Electrical Engineering · 2009
In view of current power system GIS and the defect of frequent bulge of SF6 circuit breaker caused by partly use of air-pressure system,and the blind area of how to effectively find leak point in time,the leakage detecting methods of GIS and SF6 circuit breaker air-pressure system are expounded in detail.The different methods are compared through practical operation.On this basis,a detecting method adapting to present practical operation of power system is proposed,which enables the operator to effectively find out leak point in time.
