Isolation vehicle for high-voltage switch cabinet

Abstract

The invention discloses an isolation vehicle for a high-voltage switch cabinet. The isolation vehicle for the high-voltage switch cabinet includes a heat radiation system and an isolation vehicle body, a support assembly bears the heat radiation system and the isolation vehicle body, the isolation vehicle body includes an insulating cylinder, a first contact assembly and a second contact assembly, the insulating cylinder is of a hollow structure, the first contact assembly and the second contact assembly are arranged on the insulating cylinder in sequence and are communicated with the inside of the insulating cylinder, the heat radiation system includes a radiator and a fan, the radiator and the blower fan are arranged at the top and the bottom of the insulating cylinder respectively, and an air outlet of the fan is opposite to the radiator, thereby enabling a heat radiation channel to be formed inside the insulating cylinder. The red copper tubular radiator is mounted on a first wire outlet base of the structure, cooling is realized through convection between the axial flow fan mounted under a second wire outlet base and the top of the insulating cylinder, and the top of a cabinet body is equipped with a fan used for ensuring timely emission of heat generated by 4000A current.

Description

technical field [0001] The invention relates to the technical field of isolation vehicles for switch cabinets, in particular to an isolation vehicle for high-voltage switch cabinets. Background technique [0002] With the increase of current electrical equipment, the load of electrical equipment is also developing towards high voltage and high current. At present, the KYN61 cabinet uses a 40.kV isolation handcart with a maximum current of 3150A. The original 3150A isolation vehicle adopts the following scheme: insulators are fixed to isolate the busbars, and the phase-to-phase insulation is treated with high-voltage heat-shrinkable tubes. [0003] When the current is increased to 4000A, the previous insulator fixed busbar scheme can no longer achieve the corresponding current carrying capacity and heat dissipation treatment. In order to meet the current needs of 4000A isolated handcarts for KYN61 cabinets, the problems of current carrying, heat dissipation and the strength...

Problems solved by technology

[0003] To increase the current to 4000A, the previous insulator-fixed busbar scheme could no longer achieve the corresponding current-carrying capacity and heat dissipation treatment. In order to meet the current demand for 4000A isolation handcarts for KYN61 cabinets, the problems of current-carrying, heat dissipation and the strength of corresponding parts must be solved
