Pin-pulling pliers for replacing tensile insulators with ground potential of transmission lines and using methods thereof

Abstract

The invention discloses a pair of pin pulling pliers for replacing a tension insulator of a ground potential of a power transmission line and a use method of the pin pulling pliers. The pair of pin pulling pliers comprises a connecting base, rapid work connectors, a connecting rod, a connecting pull ring, a fan-shaped hinge transmission sheet and a pair of flat nose pliers. The pair of flat nose pliers comprises a pliers head, a pliers head connecting rod and a curved pliers head connecting rod. The fan-shaped hinge transmission sheet is fixedly connected to the connecting base. The two rapid work connectors are arranged at the two ends of the connecting base. One end of the connecting base is fixed to the fan-shaped hinge transmission sheet in a hinged mode. The other end of the connecting rod is fixedly connected to the connecting rod pull ring. The pliers head connecting rod and the connecting rod pull ring are fixedly connected with each other. The connecting base is sleeved with the curved pliers head connecting rod. According to the pair of pin pulling pliers for replacing the tension insulator of the ground potential of the power transmission line, the two rapid work connectors acting in different directions are integrated on the pair of pin pulling pliers, so that the pair of pin pulling pliers are suitable for sockets with different opening directions, the labor intensity of operation personnel is relieved to the maximum extent, and the frequency of replacement of special operation ends is reduced to the maximum extent.

Description

technical field [0001] The invention relates to a tool for live maintenance of a high-voltage transmission line, in particular to a tool for replacing a tension insulator with ground potential of a 110kV-220kV transmission line and a method for using the tool to replace a tension insulator. 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 our country, the live work of replacing 110kV-220kV tension insulator strings is mainly carried out by means of equipotential work. Compared with ground potential work, equipotential work has higher work intensity, requires more personnel, and complex procedures, and the elec...

Problems solved by technology

[0004] The purpose of the present invention is to propose a simple structure, easy to use, and can effectively reduce the work force for the technical problem that the ordinary pin puller cannot pull out and restore the spring pin during the ground potential operation when the strain insulator is replaced by the ground potential of the 100kV-220kV transmission line. The labor intensity of personnel is reduced, and the pin pulling pliers for pulling out and restoring the spring pin during the replacement of the tension insulator at the ground potential can be safely, conveniently and efficiently completed
