Abstract

The invention provides a strain insulator string live replacing device for a high-voltage transmission line. The strain insulator string live replacing device comprises a stringing screw, an insulation pull plate, a front clamp, a rear clamp and an insulation bracket, wherein one end of the insulation pull plate is fixedly connected with the stringing screw, the other end is fixedly connected with the front clamp, the stringing screw is arranged on the rear clamp, the insulation bracket sleeves the insulation pull plate in a sliding mode, a front clamp groove is formed in the front clamp, and a rear clamp groove is formed in the rear clamp. When the strain insulator string live replacing device is applied to operation of replacing ground potential strain double-string composite insulators (one string of the ground potential strain double-string composite insulators) in a live mode, the fault strain double-string composite insulators (one string of the fault strain double-string composite insulators) of a strain pole (tower) can be successfully replaced. Furthermore, equipotential operators are prevented from entering the electric field directly, the labor intensity is reduced, and the operation safety is improved.

Description

technical field [0001] The invention belongs to the technical field of live maintenance tools for high-voltage transmission lines, and in particular relates to a live replacement device for tension insulator strings used in high-voltage transmission lines. Background technique [0002] With the progress of society and the acceleration of economic construction, power customers have higher and higher requirements for high-quality and reliable power supply provided by the power sector. Live working maintenance can not only provide users with continuous and uninterrupted power supply, but also improve the power supply reliability of the power grid. [0003] At present, in my country, the replacement of 110kV-220kV tensile double-string composite insulators (one of them) is mainly carried out by means of equipotential work. Compared with ground potential work, equipotential work has higher work intensity, and the electric field radiation and operation safety risks suffered by eq...
