Wire crimping repair device and method of substation

Abstract

The invention provides a wire crimping repair device and method of a substation. The wire crimping repair device of the substation comprises a wire repair tube, hydraulic crimping pliers, a clamping execution unit and a mechanical arm, wherein the hydraulic crimping pliers comprise a handle of a crimping switch and a crimping part, the clamping execution unit comprises a clamping shaft, a left clamping support arm and a right clamping support arm, the clamping shaft penetrates through the handle and is fixed at two sides of the handle, one end of the left clamping support arm and one end of the right clamping support arm are connected by a support arm connection shaft, the other ends of the left clamping support arm and the right clamping support arm are connected with a clamping adjustment shaft arranged in a groove, and the mechanical arm is used for moving the hydraulic crimping pliers to a wire position to be repaired and controlling the clamping adjustment shaft to move in the groove so that the support arm connection shaft is driven to move towards the crimping switch and trigger the crimping switch. By the wire crimping repair device, the requirement of wire crimping in the substation is met, the operation safety of an operator is ensured, the working strength of manual operation can be effectively reduced, the crimping efficiency and the automatic level are improved, and a positive change effect is generated for a wire crimping repair operation mode of the substation in China.

Description

technical field [0001] The invention relates to the technical field of special tools for substations, in particular to a device and method for crimping and repairing wires in a substation. Background technique [0002] The overhead line in the substation has been exposed to the outdoor environment for a long time. In the harsh environment such as wind, sun and sun, the steel core aluminum stranded wire often has the phenomenon of wire breakage. In this case, it is necessary to repair the wires to prevent the further expansion of the loose strands of the steel-cored aluminum stranded wires, resulting in a reduction in the mechanical strength of the lines and causing safety accidents. It can be seen from the relevant regulations that when the strength loss of the damaged wire at the same place exceeds 5% but less than 17% of the total breaking force, and the damage to the cross-sectional area does not exceed 25% of the total cross-sectional area of ​​the conductive part at the...
