Abstract

The invention relates to an inlet wire sleeve; an inlet wire casing is provided with a connecting flange, and fixed on a solid insulation casing via a flange connecting mode; a vacuum explosion chamber is arranged in the inlet wire casing of the inlet wire sleeve, and fixed on the solid insulation casing in order via the inlet wire sleeve, thus solving the problems that an existing split type partconnecting process cannot ensure the vacuum explosion chamber electrical performance requirements, i.e., splitting the vacuum explosion chamber in an original solid insulation casing, realizing ordered control of an electric field, and preventing partial discharge problems.

Description

technical field [0001] The invention belongs to the technical field of high-voltage power distribution equipment, and in particular relates to a split-type incoming line bushing for a solid-insulated 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 be...
