Abstract

The invention relates to a three-phase solid insulating shell. By splitting a solid insulating ring main unit into an insulating shell and a line inlet and outlet component, detachment of conducting elements including embedded copper bars and the like in an original solid insulating shell is realized and then inserted into the insulating shell through flange connection to realize ordered control of an electric field, and the problem of local discharge is avoided. A vacuum arc-extinguishing chamber is removed out of the insulating shell and can be mounted on the insulating shell through a connection flange, and independent pouring forming of the shell is realized. High industrial yield and technical simplicity are realized, and the problem of deformation in an insulating shell shaping process due to the internal vacuum arc-extinguishing chamber is avoided. By means of flange connection, requirements on same airtightness and electrical performances of an original integral shell are met,limitation of conventional technical thinking is broken through, and problems of low size and structural precision, difficulty in processing and forming, proneness to local discharge and difficulty incontrol of the electric field in an existing solid insulating shell are solved.

Description

technical field [0001] The invention belongs to the technical field of high-voltage power distribution equipment, and in particular relates to a three-phase solid insulating shell for a solid insulating ring network cabinet. Background technique [0002] Most of the traditional ring network cabinets are gas insulated ring network cabinets. SF6 gas is used as the insulation or breaking medium of the high-voltage live part. Since SF6 gas will decompose and produce toxic gas after it is disconnected, and it is easy to leak, the sealing requirements for the box are high and the processing technology is complicated, which makes the maintenance and testing of the gas-insulated ring network cabinet more complicated, and regular leak detection and gas replenishment are required. In addition, according to the "Kyoto Protocol", as the insulation or breaking medium of the gas-insulated ring main unit, SF6 gas is clearly listed as one of the greenhouse gases, and its use is required to...
