A rapid performance inspection device for high-voltage insulating parts

Abstract

The invention discloses a fast performance test device for high-voltage insulation members. The device comprises a rack, a first inflation compartment formed in the rack through a first rotating device, a second inflation compartment formed in a second rotating device which is slidably mounted on the rack, and a second inflation compartment driving mechanism mounted on the rack. The second inflation compartment driving mechanism drives the second rotating device to reciprocate linearly on the rack and correspondingly drives the second inflation compartment to reciprocate linearly on the rack so as to realize splicing and separation between the first inflation compartment and the second inflation compartment. According to the device, by arranging multiple groups of busbar casing pipe assemblies consisting of insulating casing pipes, casing pipe conductive sleeves and busbars in the two inflation compartments, performance acceptance work of multiple groups of busbar connecting apparatuses can be carried out at the same time; by inserting gas high-voltage components such as voltage adapters and silicone rubber casing pipes to the busbar casing pipe assemblies, tests of the componentscan be carried out at the same time. The work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of switchgear inspection, in particular to a rapid performance inspection device for high-voltage insulating parts. Background technique [0002] The silicone rubber bushing used for busbar connection is used as a key high-voltage component to ensure insulation performance after the electrical connection between gas-insulated switchgear cabinets. Its quality and reliability directly affect the overall performance of the switchgear. The silicone rubber sleeve is generally cast from silicone rubber, and the middle section is poured with semiconductor paint, and the grounding spring is used to achieve reliable grounding. The inner wall of the product is sprayed with a semi-conductive paint layer, which plays the role of electric field shielding. According to the different voltage and current of switchgear, silicone rubber bushings are available in various sizes and specifications. [0003] As a device for hig...

Problems solved by technology

[0005] The performance testing device for insulation parts cannot carry out the performance acceptance of the busbar silicone rubber bushing and voltage adaptation at the same time. The high-voltage adapters for testing the inner and outer cones need to be disassembled and replaced with corresponding specifications of the inner and outer cone bushings, which requires a lot of work.

[0006] The splicing between the existing devices for testing the performance of the silicone rubber bushing of the busbar needs to be completed manually, the centering degree between the inner cone bushings is poor, and the installation position of the silicone rubber bushing is not correct, resulting in creepage breakdown of the product along the surface during the test.
