10kV sulfur hexafluoride gas pressure relief ring main unit

Abstract

The invention relates to a 10kV sulfur hexafluoride gas pressure relief ring main unit, and belongs to the technical field of power distribution equipment. Comprising a cabinet body and a U-shaped cover, a cabinet door is arranged on the cabinet body, pressure relief openings are formed in the two sides of the cabinet body respectively, pressure relief windows are fixedly installed outside the pressure relief openings, the U-shaped cover is arranged outside the cabinet body and fixedly connected with the cabinet body, a through hole is formed in the top of the U-shaped cover, a second pressure relief assembly is arranged above the through hole, and the second pressure relief assembly is fixedly connected with the cabinet body. The second pressure relief assembly comprises a mounting frame and a top cover, square air outlets are formed in the periphery of the mounting frame, the bottom end of the mounting frame is fixedly connected with the U-shaped cover, side cover plates are arranged on the outer sides of the square air outlets, the top ends of the side cover plates are rotationally connected with the mounting frame, and the top cover is connected to the top ends of the mounting frame and the side cover plates in a sleeving mode. A reset assembly used for resetting the top cover is further arranged in the mounting frame. The ring main unit solves the problems of poor safety during pressure relief and the like of the ring main unit in the prior art.

Description

technical field [0001] The invention relates to a 10kV sulfur hexafluoride gas pressure relief ring network cabinet, which belongs to the technical field of power distribution equipment. Background technique [0002] At present, the insulation of 10kV ring main unit is mainly based on gas insulation, return body insulation and environment-friendly gas insulation. Gas insulation is currently mainly SF6 gas. SF6 gas has very stable chemical properties and has excellent insulation and arc extinguishing properties. SF6 gas-insulated ring network cabinets are small in size, compact in structure, and extremely adaptable. [0003] For traditional gas ring network cabinets, for the 10kV power distribution project indoor sulfur hexafluoride gas ring network cabinet, the pressure relief port of the switch is located in the middle and lower parts and the middle and upper parts. Then the pressure is released from the pressure relief port; when the pressure relief port releases the pres...

AI Technical Summary

Problems solved by technology

[0006] In order to overcome the shortcomings of existing ring network cabinets such as poor safety during pressure relief, the present invention designs a 10kV sulfur hexafluoride gas pressure relief ring network cabinet. When a fault occurs in the present invention, the SF6 gas in the cabinet can pass through the Specific pressure relief channels will not endanger the safety of on-site staff, and at the same time ensure that adjacent equipment will not be affected by faulty equipment
