Embodiment 1

[0021] like figure 1 , 3 As shown, it is the operation of replacing and adding large edge glass insulators when the hanging point angle iron does not drink water. A screw wrench is provided on the screw 1, a fixed beam 8 is arranged between the screw 1, and a fixed pin is arranged on the fixed beam 8 2. 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 is fastened by the card slot and the ingot screw .

Embodiment 2

[0023] like figure 2 As shown, 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.

[0024] The working process of the present invention is as follows.

[0025] 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...

Abstract

The invention relates to an aerodynamic disc-shaped suspending type glass insulator replacing clamp which is suitable for operation of professionally replacing and adding a large-edge glass insulator under a live-working condition in the process of electricity transmission. According to the structure, the aerodynamic disc-shaped suspending type glass insulator replacing clamp is characterized in that a fixing girder is arranged between screw rods, a fastener is arranged on the fixing girder, and a socket clamp is connected with the lower portions of the screw rods. According to the aerodynamic disc-shaped suspending type glass insulator replacing clamp, the large-edge glass insulator can be replaced easily, the socket clamp is installed on angle iron arranged above a hanging point, ground electric potential operation is conducted by an operator, the operation is conducted in a position away from a strong electric field, safety of live-working is improved to a great extent, working intensity of the operator is reduced, operation cost is reduced, advantages are provided to the performance of the live-working, defect elimination can be conducted on the ground electric potential operation in time, safe and stable operation of a power network is guaranteed, reliability of power distribution of an electric transmission line is effectively improved and the aerodynamic disc-shaped suspending type glass insulator replacing clamp can be popularized and used in the professional electricity transmission and production easily.

Description

technical field [0001] 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 [0002] 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 powe...
