Problems solved by technology

However, the adjustable closed clamps that adjust the position of the clamps distributed on the circumference of the clamps by screws to adapt to the change of the shape and size of the steel cap, there are multiple clamps that are adjusted separately and the operation is heavy, and the synchronization of the operation of the clamps is low, which is easy to cause The defect that the fixture is damaged due to partial load and causes a disconnection accident

Abstract

The invention relates to an insulator replacement device and method enabling chucks to be adjusted synchronously. The device comprises a rear clip, a tightener and a front clip, wherein the rear clipand the front clip are each provided with a base and an upper cover, the upper cover is hinged with one side of the base, the other side is locked, the upper cover and the base are buckled so as to form a hole fit with the shape of an insulator steel cap, a corresponding hole is provided with an adjustable, telescopic clamping apparatus in a circumferential direction, and the clamping apparatus clamps the insulator steel cap. According to the insulator replacement device and method enabling chucks to be adjusted synchronously, two clamping apparatuses are arranged on the rear clip and the front clip, so that labor intensity of workers working at high altitude is lowered, the insulator is replaced more efficiently, and the service life of the insulator clamping apparatus is prolonged.

Description

technical field [0001] The invention is used for the replacement of UHV insulators, especially an insulator replacement device and method with synchronously adjustable chucks. Background technique [0002] Replacing damaged insulators is an important task in the maintenance of UHV transmission lines. Insulators are electronic components used to support wires and to provide sufficient safety distance and insulation between the wires and the earth and towers. In the operation of transmission lines, insulators are exposed to wind, rain and lightning in the wild, and work under long-term strong electric fields and tensions, which are prone to low or zero values. Zero or low values ​​in the same string of insulators will affect the voltage distribution of the entire string of insulators and promote the deterioration of other insulators. When the number of good insulators in the string does not meet the safety regulations, it will threaten the safe operation of the transmission l...
