Description

Aerodynamic Disc Suspension Glass Insulator Replacement Fixture

technical field

The invention relates to an insulator replacement tool, in particular to an aerodynamic disk-type suspended glass insulator replacement jig, which is suitable for live replacement and addition of large-edge glass insulators in the field of power transmission.

Background technique

At present, most of the insulation combinations of 220kV lines are straight line series. The cross-arm end is a large-edge glass insulator, and the lower end is a composite insulator. Because the line is struck by lightning, the insulation value of the large-edge glass insulator is low, and there are flashover marks on the surface, so it is not suitable for further operation. And find the fault point of the next lightning strike. In addition, in order to improve the insulation level of the line, some of them were only synthetic insulators, and the large edge glass insulators are also gradually added at present, but most of them can only be replaced or added after power failure in the prior art.

Contents of the invention

Aiming at the problems in the above-mentioned prior art, the present invention provides an aerodynamic disc-type suspension glass insulator replacement jig, which solves the problem in the prior art that operators must directly lift the wires to transfer the load.

Technical scheme of the present invention is as follows:

Fixed beams are arranged between the leading screws, fasteners are arranged on the fixed beams, and bowl head clamps are connected to the lower part of the leading screws.

The fasteners are fixing pins or protective splints.

The fixed pin is fixed on the angle iron by the ingot screw.

The protective splints are four V-shaped plates.

The bowl head fixture is fastened with a card slot and ingot screws.

The bowl head fixture is matched with the insulator bowl head.

A lead screw wrench is provided on the lead screw.

The advantages and effects of the present invention are as follows:

It is very easy to replace the large edge glass insulator. The fixture is installed on the angle iron above the hanging point. The operator works at the ground potential and operates away from the strong electric field, which greatly improves the safety of live work, reduces the labor intensity of the operator, and reduces the operating cost. , to provide favorable conditions for carrying out live-line work, it can timely eliminate the lack of ground potential work, ensure the safe and stable operation of the power grid, effectively improve the reliability of power supply of transmission lines, and be easy to promote and use in power transmission production.

Detailed ways

The present invention will be described in detail below in conjunction with specific embodiments with reference to the accompanying drawings.

Example 1

As shown in Figures 1 and 3, for the replacement and addition of large edge glass insulators when the hanging point angle iron does not drink water, a screw wrench is provided on the screw 1, and a fixed beam 8 is installed between the screw 1, and the fixed beam 8 There is a fixed pin 2 on the top, and the fixed pin 2 is fixed on the cross-arm angle iron 3 through the ingot screw. The lower part of the lead screw 1 is connected with the bowl head fixture 6 matching the insulator bowl head. The bowl head fixture 6 adopts a card slot Fasten with ingot screws.

Example 2

As shown in Figure 2, when drinking water for the hanging point angle iron, replace and increase the large edge glass insulator operation, the fixed beam is fixed by the protective splint 7, and the protective splint 7 is 4 V-shaped plates. Other structures are with embodiment 1.

The working process of the present invention is as follows.

The operator places the fixture fixing beam directly above the hanging point of the cross-arm. If the work is live, it needs to wear a qualified pressure equalizing suit, move the fixing pin to the cross-arm angle iron, and tighten the ingot screw. If the cross-arm angle iron is installed in place When the water is in the water, use the protective splint to fix the fixture to fix the beam, adjust the screw wrench, adjust the insulator bowl fixture to the position where it can be stuck on the insulator bowl, clamp the bowl fixture and the bowl firmly, and tighten the screws. Check the connection of each part, hang the wire protection rope well, and choose to hang the insulating rope for live work. After the inspection is correct, move the lead screw, lift the whole fixture, and drive the insulator to lift. When the insulator is lifted to the point where the ball head can come out of the bowl head , stop the lifting, check again that the connection of each part is correct, pull out the bowl head spring pin, that is, the pin, pull out the pin of the big edge glass insulator, take out the big edge glass insulator, and install and remove the fixture in reverse order.

The scope of protection of the present invention is based on the claims, and is not limited by specific embodiments.
