specific Embodiment 1
[0038] The gas-insulated metal-enclosed switchgear in this embodiment includes a housing and a functional unit (not shown). The functional unit includes a circuit breaker, a disconnector, a grounding switch, a transformer, and a busbar. Each functional unit is sealed and arranged in a grounded shell. In the body (not shown), a conductive connection structure is provided between the conductively connected functional units. In other embodiments, the number of functional units can be selected according to actual needs, or according to actual needs, a conductive connection structure in the prior art can be arranged between some functional units that are conductively connected, and a conductive connection structure in the prior art can be arranged between some functional units that are conductively connected. The conductive connection structure in Embodiment 1.
[0039] In this embodiment, the housing is a metal cylindrical structure, and the axial ends of the cylindrical structure...
specific Embodiment 2
[0051] Its difference with specific embodiment 1 is:
[0052] The rod body is an integrated hollow tubular structure. The end of the rod body has an opening connecting the space inside and outside the rod body for gas circulation. The content of foreign matter and moisture in the space, it should be noted that the specific setting position of the sponge should not affect the plug-in fit between the conductive rod and the electrical connection.
specific Embodiment 3
[0054] The difference from the specific embodiment 1 is that the sponge can be directly fixed on the inner peripheral surface of the conductive joint while ensuring the weld strength and weld sealing performance at the connection position between the conductive tube and the conductive joint.
[0055] In other embodiments, the sponge can also be directly fixed on the inner peripheral surface of the conductive pipe to avoid metal particles and moisture inside the rod from escaping from the weld to the In the gas-insulated space, it helps to reduce the content of metal particles and moisture escaping from the rod body into the gas-insulated space. .
