Problems solved by technology

But before the method is used, the phase conductors (that is, 6-8 conductors) must be tightened at the same time, and some specific connecting components, such as connecting plates and special matching fittings, must be used together with the second and second conductors. Cooperate with the anti-winding six pulleys set in the middle of the three-sledge and the second-sled and three-sledge, the connection between each string of tension insulators and the cross-arm needs to be separately equipped with clamps and auxiliary devices, which is inconvenient to operate

Abstract

The invention provides a whole string tension insulator exchange device of an ultra-high voltage transmission line. The whole string tension insulator exchange device of the ultra-high voltage transmission line comprises a length-adjustable pull rod and a whole string tension insulator separation and recovery device arranged at a cross arm side, wherein one end of the length-adjustable pull rod is connected with a steering connection plate and the other end is connected with the cross arm side of an iron tower; 6-8 whole-phase wires acting on an insulator can be tightened and transferred to the length-adjustable pull rod by adjusting the length of the length-adjustable pull rod and rotating a mechanical tightening device, so that the whole string tension insulator is in a relaxed and unstressed free state; and then the whole string tension insulator is exchanged by using the whole string tension insulator separation and recovery device. According to the whole string tension insulator exchange device of the ultra-high voltage transmission line, the separation weight during live exchange of a tension insulator string of the ultra-high voltage transmission line can be reduced; easy live unilateral exchange of the insulator string is facilitated; and the work efficiency is improved.

Description

technical field [0001] The invention relates to an electric power maintenance device and a method thereof, in particular to a device and a method for exchanging a whole string of tension insulators of a UHV (1000KV) transmission line. The device and method for exchanging the entire string of tension insulators for UHV transmission lines can reduce the detachment weight of the UHV strain insulator strings when they are charged, and the fixture is not easy to slip out, which reduces the difficulty of work and facilitates the easy installation of insulator strings. The unilateral exchange of the live charge improves the working efficiency. Background technique [0002] In the past, extra-high voltage transmission lines, such as 220kV transmission lines, generally used double-split conductors, and the matching insulators also used double-string types. Its live exchange transmission line and its insulator string are important items in the live work project. It is necessary to ti...
