Multi-bundle conductor spacing fixing device

Abstract

The invention provides a multi-bundle conductor spacing fixing device, and the device comprises four support arms fixedly connected with each other, wherein the four support arms form a cross-shaped structure, the outer ends of the support arms are in threaded connection with screws, the screws are arranged in the length directions of the support arms connected with the screws, and the outer endsof the screws are rotatably connected with conductor hooks. And the rotating axis of the wire guide hook is the same as the axis direction of the screw rod. The device can provide stable and reliablesupport for an operator during maintenance, and dangerous situations such as rollover of the operator on an unstable wire are avoided; it can be ensured that the distance between the wires meets the design requirement, and standardized operation of spacer adding, spacer replacing and wire repairing is facilitated.

Description

technical field [0001] The invention relates to the field of tools for overhead power transmission line high-altitude power outage maintenance and live work, in particular to a multi-split wire spacing fixing device. Background technique [0002] EHV transmission lines are an important part of the modern power grid system, and are an inevitable requirement for the increase of power generation capacity and power load, and the extension of transmission distance. EHV transmission is one of the important symbols of the development level of the electric power industry. With the extensive development of electric energy utilization, many countries are building large-capacity hydropower plants, thermal power plants, nuclear power plants, and power plant groups, and the power resources are often far away from the load center. Only by using ultra-high voltage power transmission can the power transmission task be effectively and economically realized. EHV transmission can increase the...

AI Technical Summary

Problems solved by technology

[0005] After long-term operation of ultra-high voltage transmission lines, a series of defects such as "conductor damage and broken strands" will appear, requiring operators to walk along the sub-conductors to the operating point for maintenance. If trampled by the operator, it will greatly deviate from its original position, which will affect the maintenance work, and in severe cases, it will not be possible to work, and because the sub-conductor is unstable, personnel are prone to rollover, slipping, etc., which will affect the safety of the operation

For above-mentioned situation, still do not have special tool utensil or method to solve at present

[0006] In the production and maintenance work, the 500kV transmission line with four-split conductors is most likely to have this problem. On the one hand, the distance between the spacers of the 500kV transmission line can reach 60 meters, and the large span leads to large sag; on the other hand, it is Conductors with less than four splits cannot walk along sub-conductors, and conductors with more than four splits can still maintain overall stability when a single sub-conductor is damaged.
