Problems solved by technology

[0002] In the existing switchgear system, when the busbar passes through the high-voltage metal-enclosed switchgear, the busbar insulating bushing must be used. Although the existing busbar insulating bushing can play a certain role in isolation, in the bushing, The local electric field intensity is very uneven, which is easy to cause local air gap discharge. Long-term discharge will reduce the insulation performance of the bushing, and there are certain safety hazards

Abstract

The invention discloses an insulating sleeve for a busbar. The insulating sleeve of the busbar comprises a sleeve body, wherein a plurality of insulating partition plates are arranged in an inner cavity of the sleeve body, and an insulating protective sleeve clings to the inner wall of the sleeve body; and a shield grounding protective layer clings to the outer wall of the sleeve body. According to the insulating sleeve for the busbar, the insulating partition plates are arranged in the inner cavity of the sleeve body to be used for supporting the busbar in the sleeve, the insulating protective sleeve clings to the inner wall of the sleeve body to greatly enhance the insulating property of the insulating sleeve, and meanwhile, the shielding grounding protective layer clings to the outer wall of the sleeve body to allow the electric field intensity in the sleeve to be uniformly distributed, and thereby the problem that the reduction in the insulating property of the sleeve caused by partial air gap discharge is effectively solved, and the service life of the insulating sleeve for the busbar is prolonged.

Description

technical field [0001] The invention relates to a busbar insulating bushing. Background technique [0002] In the existing switchgear system, when the busbar passes through the high-voltage metal-enclosed switchgear, the busbar insulating bushing must be used. Although the existing busbar insulating bushing can play a certain role in isolation, in the bushing, The local electric field intensity is very uneven, and it is easy to cause local air gap discharge. Long-term discharge will reduce the insulation performance of the bushing, and there are certain safety hazards. Contents of the invention [0003] The technical problem mainly solved by the invention is to provide a busbar insulating bushing with simple structure, good insulation effect, safety and reliability, and long practical life. [0004] In order to solve the above technical problems, a technical solution adopted by the present invention is to provide a busbar insulating bushing, including a bushing body, the ...
