Linear tower upside-down mounting line rack insulator chain geoelectricity charged replacing device

Abstract

The invention provides a linear tower upside-down mounting line rack insulator chain geoelectricity charged replacing device, relating to an insulator replacing apparatus. Central projections (6) of two connecting rods (5) connect with an end of two stay wires (4) respectively. Central parts of the two stay wires (4) are connected to grooved pulleys (3) of two support bars (1). The other ends of the two stay wires (4) are tightening ends, wherein end line rods (10) and the connecting rods (5) are high strength nylon, and the stay wires (4) are nylon material. In the invention, through tightening the stay wires by using manual traction or coiling equipment, the end line rods are driven to rise to transfer pressure of a lead, and an insulator chain can be replaced easily. According to the invention, an effect of not cutting off power supply and avoiding electric field distortion is realized, a disadvantage that cutting off the power supply is needed in a present operating mode is overcome, and a purpose of allowing a whole power transmission line to operate safely without cutting off the power supply is realized.

Description

【Technical field】 [0001] The invention relates to an insulator replacement device, in particular to a device for replacing ground live points of insulator strings of insulator strings of upside-down catenary boards on straight towers. 【Background technique】 [0002] Known high-voltage transmission line insulator strings have many adverse effects of pollution during operation, specifically manifested as: dust, saline, industrial smoke or various particles or bird droppings in the air will accumulate on the outer surface of the insulator string to form a pollution layer ;Due to the pollution layer on the surface of insulator strings of overhead transmission lines, the pollution is varied and extremely complex depending on the environment, but it can be roughly divided into two types: natural pollution and industrial pollution, but industrial pollution only appears in relatively high industrialization And places with certain pollution sources, that is to say, natural pollution ...

AI Technical Summary

Problems solved by technology

[0005] Since two pieces of angle steel are flipped into type, the space reserved in the middle is small, and when replacing the insulator string, it is necessary to lift the wire, reduce the distance between the wire and the cross arm, and transfer the load borne by the insulator string to the replacement tool, but the insulator string in the prior art The string live replacement device cannot solve the support problem of the upper space; so at present, the insulator string replacement operation can only be replaced by a power failure.
