The paper gave the installation and operation conditions of 7.2~550 kV high voltage switchgear in SGCC system in 2004, which was analyzed according to the type, voltage grade and the responsibility of fault and obstacle condition in operation. The reasons for resisting to move, miss operation and different types of fault caused by insulation, carried current and outside force were statistical to analyze. It is pointed out the existent problems in professional management, and the technical countermeasures are put forward, which can be as reference for power system operation department and high voltage switchgear manufacturer.
