Problems solved by technology

[0004] 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

Abstract

The invention relates to a bypass leading-up cable fixing device which comprises an insulating rod (1), three vertical bidirectional clampers (2) sleeved on the insulating rod, and two angle iron clamping fixing parts (3) which are arranged at front end of the insulating rod and used for clamping two ends ofan aluminum alloy piece (4), wherein each vertical bidirectional clamper is designed by butt joint of two fasteners at 90 degrees, one portion is connected with a cover and fixed on the insulating rod, and the other portion is used for fixing a bypass leading-up cable fixing device; the angle iron clamping fixing parts are used for fixing the insulating rod on an iron tower; and the aluminum alloy piece is an assisting part for assisting the insulating rod to be fixed on the iron tower. The bypass leading-up cable fixing device has the beneficial effects that in bypass-to-load operation, a special tool is provided for fixing a bypass leading-up cable, and the tool is safe and reliable, is convenient to operate, can avoid the risks of principal line strand breakage and principal line breakage caused by relatively small diameters of principal lines, and can ensure the safety of operators and the safe operation of power grids.

Description

technical field [0001] The invention belongs to the field of electric equipment maintenance, and in particular relates to the fixing of the lead-up cable of the bypass during the load transfer operation of the bypass. Background technique [0002] 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 necessa...
