Walk-in temperature environmental test device for performance testing of insulators

Abstract

Provide a walk-in temperature environment test device for insulator performance testing, so that the stretching mechanism installed on the top plate extends into the high and low temperature box and is located directly above the rotating mechanism, the axis of the stretching mechanism and the rotation center of the rotating mechanism The lines are located on the same straight line, the insulator is connected with the tensile mechanism, and the insulator is stretched by the tensile mechanism to realize the tensile test of the insulator, or the lower end of the insulator is fixed with the rotating mechanism. The end of the bending mechanism applies stress to the loading position outside the insulator to realize the insulator. bend test. The invention can realize not only the tensile test of the insulator in the high and low temperature cyclic environment of high and low temperature, but also the bending test of the insulator in the high and low temperature cyclic environment in the high and low temperature box, and the inspection of the size and shape deviation of the insulator, which meets the requirements of the insulator. In the high and low temperature environment, there are many types of testing items for insulators, and the independent module design structure has high detection accuracy.

Description

technical field [0001] The invention belongs to the technical field of insulator performance testing, in particular to a walk-in temperature environment testing device used for insulator performance testing. Background technique [0002] With the development of industry, the status of power supply system has become increasingly prominent, and the stability of power supply has become the focus of attention. Insulators are an important part of transmission lines, the only electrical insulator and an important structural support. Each insulator on the transmission line must be able to work reliably in a complex climate environment, so it is necessary to perform performance tests under various simulated working conditions for each batch of insulators before use. Essential. Since there is currently no testing equipment for the tensile load performance test of suspension insulators under high and low temperature cyclic environment, and the bending performance test of rod-type pi...
