The switchgear is a sealed metal container (shell) that contains circuit breakers, grounding switches, busbar switches, mutual inductors, lightning rods, disconnectors, connecting elements and other main components. It is designed and optimized to form a whole, and is filled with SF6 gas for insulation. Therefore, it has many advantages such as compact structure, small size, light weight, small footprint, easy installation, high safety, strong environmental adaptability, diversified configuration, simple maintenance, and long service life. Therefore, it is welcomed by the domestic and foreign power industry and has developed rapidly;

[0003] The existing Chinese patent document CN202022105161.0 discloses an ultra-high voltage GIS disconnector housing, including a main body of the GIS disconnector housing, an end plate of the GIS disconnector housing, a protective structure of the GIS disconnector housing, an auxiliary support abutment structure for cooperating with the protective structure to improve its protective effect, and a reinforced reinforcement interception structure for further improving the compressive protection performance of the disconnector housing, wherein two end plates are provided, both of which are annular, and the two end plates are fixedly installed at the two ends of the main body, respectively, the main body is an annular housing, the protective structure is installed between the two end plates, and a plurality of supporting legs are provided at the bottom of the protective structure, the auxiliary support abutment structure is installed between the protective structure and the main body, and the reinforced reinforcement interception structure is installed on the outside of the protective structure.
