In the substation maintenance operation, the indoor equipment often faces the situation of replacing the conductive aluminum bar or copper bar in the installation cabinet.When the outdoor equipment is technically upgraded or overhauled, it will also encounter the situation of replacing and installing new wires and clips, and the precise positioning of the hole spacing in the process of making equipment such as conductive bars and wiring clips is particularly important. However, in the past, the determination of the hole distance mainly relied on the manual marking of the operator, and there was no special tool for fast and accurate positioning of the hole distance.This paper proposes an adjustable fast hole spacing positioning device suitable for substation maintenance operations, which can be positioned in both horizontal and vertical directions at the same time. It greatly shortens the operation time, provides favorable conditions for quantitative positioning work, and effectively guarantees the safe and stable operation of the power grid.
In the process of overhead transmission line work, we usually use the manual transmission method to transfer the working tools from the upper tower to the lower tower, this will increase the work of the rope-pulling personnel, and the rope-pulling personnel also do not have sufficient working space, which is easy to produce dangerous. The invention relates to a rope fixture for an electric power system, which is a high-altitude anti-fall steering device. The utility model comprises a cylinder body, a pulley is arranged at the bottom of the cylinder body, a rope passage is arranged in the cylinder body, and a swinging locking tongue is arranged in the rope passage. The utility model adopts a locking tongue pawl structure to control the rope passing in one direction to prevent the rope from going backwards. The pulley guide (steering) is used to make the rope slide smoothly, and the direction of pulling rope is changed from vertical direction to horizontal direction so as to increase the space of pulling rope and reduce the hidden danger of high-altitude work.
