Description

A tension insulator replacement device

technical field

The present application relates to the technical field of electric equipment, in particular to a tension insulator replacement device.

Background technique

Insulators are special insulation controls that can play an important role in overhead transmission lines. It is used to support and fix wires and live conductors, and to provide sufficient distance and insulation between live conductors or between conductors and the earth. If the insulator is used for too long, due to environmental pollution, the insulation level of the internal medium is reduced, or the insulation of the wire to the pole and tower is reduced due to the breakdown of the lightning strike insulator, which may cause a 10kV line ground fault, causing a power outage on the line and affecting the reliability of the power supply. Therefore, The 10kV tension insulator needs to be replaced irregularly.

At present, the replacement of strain insulators requires operators to reach the designated position after climbing the pole. The tools used include wire tensioners, wire clamps, wire ropes, U-shaped rings, etc. In order to prevent the wires from falling off in subsequent wire tightening operations, wire ropes must be used first. , The U-shaped ring locks the wedge-shaped wire clamp, so that the wire is fixed on the cross arm to prevent falling off. Then the staff fixes one end of the connecting body of the wire tensioner and the wire clamp on the cross arm, and the wire clamp at the other end clamps the wire to carry out the wire tightening work. After the wire is tightened to a certain extent, the tension insulator is removed. Homework done.

However, in the actual replacement operation, it is necessary to connect the wire tensioner, the wire clamp, and the wire rope as a whole on the ground. On the shoulder, as a fixed point, the size of the hook at the front end of the wire tensioner is too small to be reliably hooked on the cross arm. Therefore, in this link, the steel wire rope needs to be wound around the double cross arms and then fixed with the wire tensioner. The working mode has high requirements on the operator's working position and height, otherwise it will be very difficult to wind the wire rope; Insulators, and different operators have different arm lengths. In order to facilitate the tightening of the wires, the length of this set of tools (wire tensioners, wire clamps, and wire ropes) must be adjusted on the ground every time. The weight of the tensioner is heavy, and the adjustment of the internal twisted wires is also very inconvenient, which brings great changes to the workers working at heights, and the tensioner will reserve a long redundant twisted wire, which increases the number of workers who work at heights. The weight of the appliance increases the load of the operator on the pole; after the set of tools and appliances are connected and fixed, in the link of wire tightening, in principle, the wire tensioner is not allowed to collide with the tension insulator, but in practice The tensioner used is an all-metal structure, and there is a risk of damaging the tension porcelain insulator after a collision.
