Description

Temporary insulation holder for live connection and drain wire

technical field

The utility model relates to an auxiliary tool for connecting a 10-kilovolt electrified drain wire, in particular to a temporary holder for a drain wire when a 10-kilovolt electrified wire is connected to the drain wire.

Background technique

When connecting the drain line from the 10 kV overhead power line to the equipment or other branch lines on the ground, use a lift to lift the workers in the insulation bucket to the vicinity of the high-altitude overhead power line. The upper end is fixed on the insulating bucket, and while the insulating bucket is lifted, the upper end of the drainage wire is simultaneously lifted to the vicinity of the high-altitude overhead power line with the operator. When connecting the drain wire with electricity, the operator first installs the parallel ditch clamp on the 10 kV overhead power line, and then connects the upper end of the drain wire to the parallel ditch clamp.

In the prior art, when fixing the upper end of the drain wire on the insulating bucket, there is no special drain wire fixing tool for connecting the drain wire at high altitude. The drain wire is fixed on the insulating bucket with an insulating lock bar or a common insulating clip. When removing the drain wire from the insulation lock bar or ordinary insulation clip, use both hands. One hand opens the insulation lock bar or ordinary insulation clip, and the other hand holds the drain wire. Pull the drain wire from the insulation lock rod or ordinary insulation out of the folder.

When connecting the drain wires, the operator first installs the parallel ditch clamp on the 10 kV overhead power line, and one hand of the operator cannot leave the parallel ditch clamp, and the other hand cannot separate the insulation from the above insulation. Take out the drain wire from the lock bar or ordinary insulating clip. In order to take out the drain wire from the above insulating lock bar or ordinary insulating clip, another person needs to stand on another insulating bucket to remove it from the insulating lock bar or ordinary insulating clip. Take out the drainage line and give it to the operator. After receiving the drainage line, the operator will connect the upper end of the drainage line to the parallel ditch clamp.

Although it is not complicated to connect the drainage wire of 10 kV high-voltage electricity at high altitude, due to the high voltage, a safe distance must be ensured during operation. The safe distance of 10 kV high-voltage electricity is 300 mm. When connecting the drainage wire at high altitude There is no applicable special drainage wire fixing tool. When connecting the drainage wire, two people and double insulating buckets are needed, which wastes equipment and labor.

Contents of the invention

The purpose of the utility model is to overcome the above-mentioned shortcomings, and propose a temporary insulation holder for live connection and drainage wire that can save equipment and labor when connecting the drainage wire.

The utility model is realized by following method.

The temporary insulating holder for live connection and drain wire has an insulating rod with a length greater than the safety distance of 100 mm to 200 mm, and the upper and lower ends of the short insulating rod are respectively connected with ground wire clamps.

When in use, before the insulation bucket is lifted, use the utility model to clamp the upper end of the drain wire on the lower ground wire clamp of the utility model, clamp the upper ground wire of the utility model on the insulation bucket, and lift the insulation bucket At the same time, the upper end of the drainage line is lifted to the vicinity of the overhead power line along with the operators. When the operator is electrified to connect the drain wire, the utility model holding the drain wire is first removed from the insulating bucket, the upper ground wire of the utility model is clamped at an appropriate position on the overhead wire, and then the utility model is clamped on the 10 kV overhead power line. Install the parallel ditch clamp on the live line, after installing the parallel ditch clamp on the 10 kV overhead power line, hold the parallel ditch clamp with one hand, and use the other hand to clamp the parallel ditch clamp on the ground wire at the lower end of the utility model. Take out the drainage wire, and then fix the drainage wire on the parallel groove clamp.

The utility model has insulating rods, and the upper and lower ends of the short insulating rods are respectively connected with ground wire clamps, which can be conveniently hung at a suitable position near the operation, and can also be conveniently clamped by one hand. The utility model relates to taking out the drain wire on the ground wire at the lower end, which is a special holder for the drain wire that can save equipment and manpower when the 10 kV overhead power line is live connected to the drain wire.

Below in conjunction with accompanying drawing, the utility model is described further.
