Embodiment Construction
[0021] Examples of switchgear are Figure 1~2 As shown: the switch cabinet 1 includes a cabinet body 2 and a busbar connector 13 which is insulated from the cabinet body 2 through a disc insulator 14. The busbar connector 13 has an incoming line end and an outgoing line end. The end is connected with the busbar connector 13, and the tail end is bent to the outlet end elbow on the left side of the busbar connector 13. The outlet end elbow is composed of a folded plate fixedly connected with the busbar connector 13 by bolts. The tail end of the outlet end elbow An aluminum conductive rod 4 is fixedly connected to the bolt connection structure 3, and the end of the conductive rod 4 away from the busbar connector 13 is provided with a conductive plug for electrical connection with the conductive socket of the busbar connector of the corresponding matching cabinet 17. 5. The incoming line end of the busbar connector 13 is provided with an incoming line end elbow whose head end is ...

Description
technical field [0001] The invention relates to a gas insulated switchgear, in particular to a three-position switchgear and its bus connection structure. Background technique [0002] Existing air cabinets and inflatable cabinets are collectively referred to as switch cabinets. Both air cabinets and inflatable cabinets include a cabinet body. The cabinet is insulated and equipped with a busbar connector. The busbar connector has an incoming line end and an outgoing line end. Because of the actual needs of some power distribution schemes, sometimes the scheme of connecting the air cabinets in a group of inflatable cabinets is adopted. Because the structures of the two switch cabinets are different, it is necessary to connect the cabinets between the inflatable cabinets and the air cabinets. Consider setting up targeted linkage mechanisms. Existing connection mechanisms such as "a connection mechanism between an inflatable cabinet and an air cabinet" disclosed in Chinese pat...
