Substation live working wire repair system and method

Abstract

The invention discloses a wire repairing system and method for hot-line work of a transformer substation. The wire repairing system comprises a shell; a driving mechanism is arranged in the shell; thedriving mechanism is connected with a left clamping arm and a right clamping arm separately to drive the left clamping arm and the right clamping arm to realize opening and closing movement; a base used for fixing a repairing piece is arranged between the left clamping arm and the right clamping arm in a direction perpendicular to the movement direction of the clamping arms; and wire combining devices are arranged at the two ends of the base respectively. The wire repairing system has the beneficial effects that the mechanical arms are used for clamping the wire repairing devices for conducting wire repairing operation, so that characteristics of high mechanical degree, high automatic degree and the like are achieved, the requirement for crimping of wires in the transformer substation ismet, and the operation safety of an operator is guaranteed. By virtue of the device, the working intensity of manual operation can be effectively lowered, and the crimping efficiency and the automation level are improved, so that a positive change effect is generated on the wire crimping and repairing operation mode of the transformer substation in China.

Description

technical field [0001] The invention relates to the technical field of substation live maintenance operations, in particular to a system and method for repairing live wires in substations. Background technique [0002] With the continuous development of society, the development of the power grid is faced with the demand for high power supply reliability, high load density, and high power quality. Users have increasingly strict requirements for power outage time. It is difficult to arrange power outages for important key lines, and there are more and more opportunities for power outage maintenance. few. [0003] The overhead line in the substation is exposed to the outdoor environment for a long time, and the steel-cored aluminum stranded wire often breaks when it is exposed to harsh environments such as wind, sun, and the sun. When the line is running, vibration and strands will also occur due to the action of external forces. , In this case, it is necessary to repair the w...

AI Technical Summary

Problems solved by technology

The existing wire repair device cannot realize intelligent repair;

[0008] (3) In the prior art, the wire repair sheet inevitably has the problems of loose crimping and rotation during the crimping process, which cannot guarantee the repair quality of the wires

[0009] (4) The material of the wire repairing device in the prior art is metal, which cannot realize live work, and the safety is poor
