This study analyzed a frequent failure of the hydraulic mechanism of the 800 kV tank circuit breaker in Pingliang transformer substation, examined the pressure control, safety valve, and voltage limiting resistance, and checked the pressure parameter setting of the hydraulic mechanism. Consequently, the cause of the failure was discovered, and a countermeasure was taken to completely eliminate this failure. Source

Lanzhoudong substation 750 kV change a selection of GIS equipment, products, currently the I paragraph 750 kV busbar for domestic GIS devices to run up the closed bus, install a number of bus after the end of tube connection, such as surface leakage fault. Based on an analysis of anchors and bellows displacement, the main reason for the defects found anchors design and bellows adjustment problems. Finally, there is a corresponding transformation put forward proposals. Source
