Problems solved by technology

[0003] The existing modular 10kV prefabricated cabin and 35kV prefabricated cabin high-voltage cabinet adopt double-row arrangement, and the busbar connection of the two rows is designed with an overhead busbar bridge. Adding 1.5 meters to the foundation of the bridge does not meet the height limit requirements of road transportation, and greatly increases the cost of the prefabricated cabin frame; in addition, in the prior art, the busbar bridge is on the top of the high-voltage cabinet, and the maintenance of the small busbar on the top of the cabinet cannot be completed

Abstract

The invention provides a novel high-voltage prefabricated cabin bus bridge and a wiring method thereof, and the novel high-voltage prefabricated cabin bus bridge comprises a side connecting frame anda bottom connecting frame, which are both of a frame structure and are in full-splicing connection; and the bottom connecting frame is located in a bottom foundation frame of the high-pressure prefabricated cabin, and the side connecting frame is located on one side edge of the high-pressure cabinet and penetrates through a bottom plate of the high-pressure prefabricated cabin to be connected withthe bottom connecting frame. The prefabricated cabin has the advantages that no bus bridge exists in the prefabricated cabin, the overall attractiveness in the cabin is improved, meanwhile, no bus bridge exists at the top of the prefabricated cabin operation channel, the height of the prefabricated cabin is reduced, the road transportation requirement is met, the prefabricated cabin cost can be reduced, and the cabinet top small bus overhaul problem is solved.

Description

technical field [0001] The invention belongs to the field of high-voltage prefabricated cabin equipment, and in particular relates to a novel high-voltage prefabricated cabin bus bridge and a wiring method thereof. Background technique [0002] In order to respond to the development needs of the State Grid intelligent substation, the new generation of intelligent substation meets the characteristics of high system integration, reasonable layout, and miniaturization, which can reduce the equipment footprint and facilitate on-site maintenance. [0003] The existing modular 10kV prefabricated cabin and 35kV prefabricated cabin high-voltage cabinet adopt double-row arrangement, and the busbar connection of the two rows is designed with an overhead busbar bridge. Adding 1.5 meters to the foundation of the bridge does not meet the height limit requirements of road transportation, and greatly increases the cost of the prefabricated cabin frame; in addition, in the prior art, the bu...
