Abstract

Disclosed is a lifter used in assembling and disassembling of a grounding wire. The lifter comprises an internal pressure storage steel pipe, a hydraulic rod, a first-section insulating rod, a motor and a control handle, wherein the first-section insulating rod is connected with the hydraulic rod; the hydraulic rod is connected with the internal pressure storage steel pipe; the internal pressure storage steel pipe is connected with a hydraulic pump; the hydraulic pump is connected with the motor; and the first-section insulating rod is provided with an electroscope. By adoption of the lifter, all problems existing in the onsite assembling and disassembling of the grounding wire can be solved; electricity verification can be carried out conveniently; and an operator can finish the assembling and disassembling of the grounding wire of a 500KV system, thereby improving the working efficiency and improving the reliability of safe operation.

Description

technical field [0001] The invention relates to an elevator for installing and disassembling grounding wires. Background technique [0002] The short-circuit grounding wire used in substations of 500 kV and above has a size of 25 square millimeters and a single-phase weight of 20 kilograms. The height of 500 kV equipment is about 16 meters. When installing and removing the grounding wire, it takes several people to work together to install the grounding wire successfully. It is also difficult for one person to lift the insulating rod when removing the grounding wire. If multiple people work together, it is difficult to make the force together, which makes it difficult to combine the slot at the top of the insulating rod with the bottom guide rod of the conductive end of the grounding wire to connect the ground. Line removed. Insulation rods are often broken and damaged during use. [0003] Before installing the ground wire, conduct an electric test on the equipment. Dur...
