Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of solid seal pole, especially to a cladding type heat conduction assembly of solid seal pole. BACKGROUND

[0002] The gas cabinet has the advantages of space saving of the cabinet, high reliability, maintenance free, small environmental pollution, etc. and is widely used in the medium voltage power distribution system. At the same time, the gas cabinet has a closed cabinet, and it is difficult to ventilate and dissipate heat in the closed space. The solid seal pole is an important device in the gas cabinet, mainly used for breaking current within the working current range, and can be operated for opening and closing, and has high reliability and service life. In the operation process, heat is generated in the solid seal pole. It needs to be cooled in time.

[0003] The utility model patent of patent application publication number CN221977818U discloses a solid seal pole, which comprises an insulating shell, a vacuum arc chamber fixed in the insulating shell, and an upper outlet seat connected to the static contact of the vacuum arc chamber. It also includes a heat conduction assembly. The heat conduction assembly has a heat-conducting and insulating contact piece. The heat conduction assembly forms a reliable and efficient heat diffusion channel. The heat diffusion path is from the vacuum arc chamber to the upper outlet seat, then to the heat conduction assembly, and finally to the outside, thereby dissipating heat from the solid seal pole.

[0004] However, the above-mentioned device still has some shortcomings in actual use: when heat is dissipated to the outside through the heat conduction assembly, the heat is dissipated through the air outside the heat conduction assembly. This way of dissipating heat is relatively slow, affecting the efficiency of heat dissipation of the solid seal pole. Utility model content
