The invention provides a walk-in type temperature environment testing device for insulator performance testing. A stretching mechanism mounted on a top plate extends into a high-low temperature box and is arranged right above a rotating mechanism; and the axis of the stretching mechanism and the rotating center line of the rotating mechanism are located on the same straight line. An insulator is connected with the stretching mechanism and is stretched by the stretching mechanism to realize the stretching test of the insulator, or the lower end of the insulator is fixedly connected with the rotating mechanism and the end portion of a bending mechanism applies the stress to a loading position on the outer side of the insulator to realize bending test of the insulator. According to the invention, the stretching testing of the insulator in the high-low temperature box with high-low temperature circulation can be realized and bending testing of the insulator in a high-low temperature circulating environment in the high-low temperature box and the inspection of the size, form and position deviation of the insulator can also be realized, so that the detection requirements of the insulatorin the high-low temperature environment are met; many detection item types of insulators are provided; and the detection precision is improved based on the mutually independent module design structures.
Description
technical field [0001] The invention belongs to the technical field of insulator performance testing, and in particular relates to a walk-in temperature environment testing device 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 insulators and important structural supports. Each insulator on the transmission line must be able to work reliably in a complex climate environment. It is necessary to perform performance tests on various simulated working conditions for each batch of insulators before use. Among them, the test of mechanical performance strength is necessary for the safe operation of the line. indispensable. Since there is currently no testing equipment applied to the tensile load performance test of susp...
