Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, specifically to an insulator power frequency arc ignition test mounting bracket. Background Technology

[0002] When conducting AC power frequency arc tests on insulator strings and insulator string assemblies, the insulator strings need to be mounted on a test bracket and fixed with a tension force before the corresponding tests and inspections can be carried out. Existing test equipment and methods have the following problems: 1. The installation process is too cumbersome, requiring a large number of personnel to work together for extended periods, resulting in wasted manpower and severely slowing down test efficiency and progress; 2. The test has certain safety height requirements for the insulator strings, making personnel prone to injury during installation; 3. As this test involves high voltage and high current, there is a possibility of insulator fragmentation and splashing that could damage other equipment. Therefore, a power frequency arc-ignition test mounting bracket for insulators is needed that can improve the efficiency of insulator string testing and provide protection for equipment behind the bracket.
