Abstract

The invention relates to the technical field of insulator testing, and discloses a high-voltage insulator detection device, which solves the problem that the close contact between a high-voltage contact and an insulator cannot be ensured at present, and comprises a base and three insulator bodies, and the three insulator bodies are all located above the base; according to the invention, through cooperation among the side sliding blocks, the top plate and the middle sliding block, the top plate can drive the high-voltage contact to move downwards and compress the second spring at the same time, and when the high-voltage contact moves to be in contact with the top end of the insulator body, the top plate continues to move downwards, so that the second spring continues to be compressed; and when the rotating plate rotates to be attached to the top of the sliding plate, the high-voltage contact is in full contact with the top end of the insulator body, so that subsequent detection on the electrical performance of the insulator body is facilitated, and the influence on a test circuit caused by insufficient contact between the high-voltage contact and the insulator body is prevented.

Description

technical field [0001] The invention belongs to the technical field of insulator testing, in particular to a high-voltage insulator testing device. Background technique [0002] An insulator is a device installed between conductors of different potentials or between conductors and ground potential components. It can withstand voltage and mechanical stress. It is a special insulation control that can play an important role in overhead transmission lines. The earth There is sufficient distance and insulation between them. Insulators are usually made of glass or ceramics. The insulators made of glass are glass insulators. The basic properties of insulators include electrical, mechanical and thermal properties. Among them, the test for the electrical properties of insulators is more important. , Electrical performance is a key factor affecting the quality of insulators. [0003] When the existing electrical performance testing devices for insulators are used, they are often det...
