Emergency maintenance equipment for uninterruptible power supply of middle-high voltage power grid

Abstract

The invention relates to emergency maintenance equipment for uninterruptible power supply of a middle-high voltage power grid. The emergency maintenance equipment comprises a live working shielding clothes body, a safety protection mechanism, a linkage clamping mechanism and an auxiliary standing mechanism which is convenient for maintenance personnel to stand for cable maintenance and repair operation. The safety protection mechanism is arranged on the live working shielding clothes body; the linkage clamping mechanism is arranged in the safety protection mechanism; the auxiliary standing mechanism is arranged on the outer side of the safety protection mechanism. The equipment has the beneficial effect that the dangerous situation that the two safety hooks are taken down at the same time due to carelessness or distraction of workers can be effectively prevented.

Description

technical field [0001] The invention relates to the technical field of power grid maintenance, in particular to emergency maintenance equipment for medium and high voltage power grids. Background technique [0002] Medium and high voltage power refers to the power supply with a voltage of 250 volts and above or the industrial power supply with a voltage of 3000-11000 volts, and the industrial power supply is basically unable to cut off the power when it is in use. When the staff maintains and repairs the cables, It is often operated with live electricity. At this time, it is necessary to use supporting equipment such as live work shielding clothing to ensure the safety of the staff. [0003] Shielding clothing for live work is suitable for continuous maintenance of overhead transmission lines and distribution lines. The main items of live work include: replacing line towers, replacing conductors, busbars and overhead ground wires, cleaning and replacing insulators, washing ...

AI Technical Summary

Problems solved by technology

[0004] However, the current live work shielding clothing often uses more than two safety ropes and safety hooks to fix the staff on the transmission cable as a whole to prevent the staff from accidentally falling, especially when the shielding clothing is used on high-altitude overhead transmission lines. The purpose of using more than two safety ropes and safety hooks is to always ensure that at least one safety rope and safety hook is fixed on the outer surface of the cable for safety protection when replacing the fixed power transmission cable. The safety mechanism used is not linked, that is to say, there is a possibility that the staff may make an operation error due to distraction. For example, after removing a set of safety ropes and safety hooks, there is no chance of distraction or chatting with the staff next to them. Fix this safety hook on the cable, and you can remove another set of safety hooks without hindrance, so there is a great potential safety hazard
