Problems solved by technology

Experience at home and abroad shows that many line accidents are caused by insulation quality problems, operating years and extreme weather conditions. The root cause is line flashover. As extreme weather around the world becomes more and more common, strengthening the inspection of insulators in extreme environments is especially Importantly, at present, the research methods of composite insulator decay and fracture tests are almost blank, and there is no device in the prior art that can carry out simulation tests of composite insulator decay defects considering moisture, electric field, and mechanical bending factors

Abstract

The invention provides bending fatigue equipment for insulators, which comprises a fog chamber, a fogging controller, a first connecting assembly, a second connecting assembly, a test composite insulator and a bending applying assembly. The fog chamber has an inner cavity. The fogging controller is arranged on the outer side of the fog chamber and is communicated with the inner cavity. The first connecting assembly and the second connecting assembly are symmetrically arranged on the two opposite side walls of the fog chamber, one end of the first connecting assembly is arranged in the fog chamber, the other end of the first connecting assembly is arranged on the outer side of the fog chamber, one end of the second connecting assembly is arranged in the fog chamber, and the other end of the second connecting assembly is connected with the corresponding side wall of the fog chamber. The test composite insulator is connected between one end of the first connecting assembly and one end of the second connecting assembly. The bending applying assembly is in driving connection with the other end of the first connecting assembly. The bending fatigue equipment has the beneficial effects that a composite insulator crisp and decay defect simulation test method considering factors of moisture, an electric field and mechanical bending is invented, and the actual operation condition of the composite insulator is effectively simulated, so that a basis is provided for model selection of the insulator.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to an insulator bending fatigue equipment. Background technique [0002] The power system is an important support for the national economy, and it is also the most complex artificial network in the world. Maintaining the stability of the power grid is an important task for the development of people's livelihood and economy, and it is also restricted by many factors. As the main carrier of connecting lines in the power grid, the insulator is an important fulcrum to support the power grid, and its importance is self-evident. Experience at home and abroad shows that many line accidents are caused by insulation quality problems, operating years and extreme weather conditions. The root cause is line flashover. As extreme weather around the world becomes more and more common, strengthening the inspection of insulators in extreme environments is especially Importantly, at present, there...
