Description

An anti-running line protector based on speed control

technical field

The invention relates to the technical field of power grid engineering construction equipment, in particular to an anti-running line protector based on speed control.

Background technique

In the construction process of transmission lines, when tightening the wires, it is necessary to clamp the wires with a wire clamp first, and then use the wire tensioner to tighten the wires, but the existing wire clamps often encounter wires being stuck in the process of use. The phenomenon of slipping in the device and the wire falling out of the clamping device, once the wire runs during the line construction, the surface of the wire will be worn, and corona will easily be generated in the process of transmitting electric energy in the future, resulting in waste of electric energy and noise. harm. On the other hand, to continue the construction after running the line, it is necessary to re-draw the conductor, which greatly causes a waste of manpower and material resources and increases the construction period. If the wire needs to pass above the insulating net during the traction process, once the traction rope breaks at this time, the traction plate may exceed the maximum bearing capacity of the insulating net when it hits the insulating net due to its heavy weight, which will damage the line facilities and cause a short-circuit accident, which is the most serious It is possible to cause personal injury or death. Especially when there are tight lines on the lines crossing highways and rivers, pedestrians, vehicles and boats may be injured if there is a running line. After research, it is found that the occurrence of running wires is closely related to construction methods, construction tools, wire models and specifications, etc. The following are several situations that are often found:

1. The wire is over-tracted during the wire tightening process, causing the wire rope of the wire tensioner to break and run away;

2. The wire does not match the clamping part of the wire clamp, and the wire slips or runs away;

3. The staff did not completely clamp the wire into the clamping part of the clamping device, and the wire running phenomenon occurred;

4. The quality of the insulating layer of the insulated wire is poor, and the inner insulating layer of the clamping part of the clamping device is broken and then runs away.

In actual construction, simple manual pulling of wires or fixing the ends of wires on poles and cross-pieces are usually used as anti-running measures for wires, which is laborious, reduces work efficiency, and has poor effect and poor safety performance.
