Problems solved by technology

[0003] At present, there is a lack of test devices for torsional and bending tests of insulators. Most of the testing equipment for insulators only has a single function, which can only be used to test the torque or bending moment performance of insulators, and cannot restore the actual environment. The insulator is subjected to the limit working state of bending moment and torque at the same time

Description

technical field [0001] The invention relates to the field of insulator testing equipment, in particular to a testing device for testing the torsion and bending performance of insulators. Background technique [0002] Insulators are special insulation controls that can play an important role in overhead transmission lines. In the early years, insulators were mostly used on utility poles, and gradually developed into a high-voltage wire connection tower with many disc-shaped insulators hanging on one end. It is used to increase the creepage distance, usually made of glass or ceramics, and is called an insulator. [0003] At present, there is a lack of test devices for torsional and bending tests of insulators. Most of the testing equipment for insulators only has a single function, which can only be used to test the torque or bending moment performance of insulators, and cannot restore the actual environment. The insulator is subjected to the ultimate working state of bending...
