Description

A bypass lead cable fixing device

technical field

The utility model belongs to the field of electric equipment maintenance, and in particular relates to the fixing of the lead-up cables of the bypass during the load transfer operation of the bypass.

Background technique

During the operation of the distribution network, maintenance and project transformation are often required. In order to improve the maintenance efficiency and reduce the impact of frequent and long-term power outages, the comprehensive non-stop power supply method is usually used for load transfer. The basic method is to temporarily transfer the load side of a line to be repaired to a live line through a bypass cable, so as to disconnect the power supply of the line to be repaired for power outage maintenance. On the one hand, the maintenance work is carried out, and on the other hand, it is guaranteed The power supply on the load side improves the reliability of power supply. In the process of bypass load transfer, it is necessary to lap the three-phase bypass lead cables on the line. In order to realize the fixation of the bypass lead cables, we usually use insulating ropes to tie the wires to the wires in the previous work process. The disadvantage of the fixed method is that when the diameter of the main wire is small, it may cause the main wire to be broken or even disconnected, which endangers the safety of the operators and the safe operation of the power grid. And this inventive device solves the problem of this work.

Disadvantages of existing working tools or working methods:

Under the existing technical conditions, insulated ropes are usually used to tie the bypass lead-up cable to the main wire during the bypass load transfer operation. This method is very easy to cause the main wire to be broken when the main wire diameter is small. Units are even disconnected, which endangers the safety of operating personnel and the safe operation of the power grid.

Contents of the invention

The purpose of this utility model is to overcome the defects of the above-mentioned prior art and provide a bypass lead-up cable fixing device which is easy to operate and can effectively reduce the operation risk.

The purpose of this utility model is achieved through the following technical solutions.

A cable fixing device for bypass leads, the utility model is characterized in that it includes a vertical two-way clamper, an angle steel clamping fixture, an aluminum alloy part and is connected with the vertical two-way clamper, an angle steel clamping fixture, and an aluminum alloy part Insulation pole, wherein the vertical two-way clamp is symmetrically arranged with two fasteners in opposite directions, one of which is used to fix on the insulation pole, and the other is used to fix the bypass lead-up cable. The angle steel clamping fixture is used to fix the insulating rod on the iron tower, and the aluminum alloy part is an auxiliary part for auxiliary insulating rods to be fixed on the iron tower.

The utility model is composed of an insulating rod connecting three vertical two-way clamps, two angle steel clamping and fixing parts and an aluminum alloy part. Among them, the vertical two-way clamper is symmetrically arranged with two fasteners in opposite directions, one of which is used to fix the insulating rod, and the other is used to fix the bypass lead-up cable. The angle steel clamping fixture is used to fix the insulating rod on the iron tower, and the aluminum alloy part is an auxiliary part for auxiliary insulating rods to be fixed on the iron tower. The utility model has the advantages of convenient portability, simple operation, standardized operation, less likely to cause broken strands of wires compared with the method of fixing with insulating ropes, and safe production.

In the operation of the utility model, when the bypass load transfer operation is performed, the bypass lead cable is fixed with a special tool, the installation process is convenient and fast, and it can be quickly installed without the need for other auxiliary tools, and the bypass lead cable After fixing, the operation risk of broken strands and broken threads of the main line caused by the small diameter of the main line is avoided to a limited extent.

The remarkable beneficial effects of the utility model are: in the bypass load transfer operation, there is a special tool for fixing the cable leading up the bypass, which is safe and reliable, and easy to operate, avoiding the The risk of main line breakage and disconnection ensures the safety of operators and the safe operation of the power grid.
