Abstract

The invention discloses an SF6 gas all-insulation ring main unit with excellent heat dissipation performance, and belongs to the technical field of electrical cabinets. An SF6 gas all-insulation ring main unit with excellent heat dissipation performance comprises an upper cabinet body, a lower cabinet body installed at the bottom of the upper cabinet body and a control box installed on the side wall of the lower cabinet body, an inner cavity of the lower cabinet body is divided into a heat dissipation cavity and a wire arrangement cavity through a partition plate, and the upper cabinet body comprises a first sealing part and a second sealing part which are slidably connected to the top of the lower cabinet body; the opposite sides of the first sealing part and the second sealing part are provided with butt joint parts which are matched with each other, the back faces of the first sealing part and the second sealing part are further provided with heat dissipation windows which are evenly distributed, heat dissipation openings of the heat dissipation windows are provided with opening and closing mechanisms, and the top of the lower cabinet body is provided with an electric appliance element installation part arranged in the upper cabinet body. A butt joint control mechanism matched with the first sealing part and the second sealing part is further arranged on the back face of the lower cabinet body. Damp-proof and heat dissipation functions in a rainy day state are realized, and meanwhile, the maintenance space is increased to facilitate later detection and maintenance.

Description

technical field [0001] The invention relates to the technical field of electrical cabinets, in particular to an SF6 gas fully insulated ring network cabinet with excellent heat dissipation performance and a use method. Background technique [0002] Ring main unit (Ring Main Unit) is a group of high-voltage switchgear installed in a metal or non-metal insulated cabinet or made into an assembled spaced ring network power supply unit.
