Abstract

The utility model discloses a special tool for disassembling and assembling high-voltage lead wires for main transformer overhaul. The special tool for disassembling and assembling includes a cover body (1), a fixed pulley (2), a rope (3) and a screw (4). ) fixed pulley (2) is installed in the center of the bottom surface, rope (3) passes fixed pulley (2), and one end of rope (3) connects screw (4). When in use, the cover body (1) is turned upside down on the casing of the main transformer, the screw (4) is inserted into the inner thread of the terminal (5), and the other end of the rope (3) is held at the same time, you can rest assured Unscrew the fixing nut (6) on the terminal post (5) slowly; after the casing is removed, you can slowly put down the rope, and unscrew the screw (4) on the terminal post (5) at the top of the climbing seat (8). ), so that the high voltage lead (7) can be obtained. The utility model has the advantages of simple structure, low cost, convenient operation, time saving and labor saving, and avoids equipment damage.

Description

Main transformer overhaul high-voltage connection tool specially for attaching and detaching

Technical field

The utility model relates to the electric power system service kit, is specifically related to a kind of main transformer overhaul high-voltage connection tool specially for attaching and detaching.

Background technology

As everyone knows, the high-voltage connection on the main transformer is to link to each other by the binding post above the sleeve pipe, and binding post is the inside and outside screw that a tooth is all arranged, binding post fixedly be securing with a big nut.Therefore, carry out in the main transformer disassemble and assemble work at the scene, when we will remove high-voltage connection, at first be hold-down nut will be screwed down, when nut was screwed onto, binding post and high-voltage connection caused equipment may occur damaging because the effect of gravity can be fallen into the transformer body interior, perhaps be not easy again high-voltage connection to be taken out, and in the process of dress, inconvenient phenomenon can occur installing.

Summary of the invention

The purpose of this utility model is: a kind of main transformer overhaul high-voltage connection tool specially for attaching and detaching is provided, adopts the dismounting of the auxiliary high-voltage connection of this instrument, and time saving and energy saving, simple and convenient, be unlikely to damage equipment again.

Technical solution of the present utility model is: this tool specially for attaching and detaching comprises cover body, fixed pulley, rope and screw, at the center of the bottom surface of cover body fixed pulley is installed, and rope passes fixed pulley, an end connecting screw of rope.

During use, the cover body left-hand thread inserts the internal thread tooth of binding post with screw on the sleeve pipe of main transformer, and the other end with rope holds simultaneously, just can turn round down the hold-down nut on the binding post relievedly; Behind the sleeve pipe of dismantling, can put down rope at leisure, at the seat screw of backing out on the binding post suitable for reading of ascending a height, thereby can get high-voltage connection.

The utility model is simple in structure, and is with low cost, easy to operate, time saving and energy saving, avoids the device damage phenomenon.

Description of drawings

Fig. 1 is a structural representation of the present utility model

Among the figure: 1, cover body, 2, fixed pulley, 3, rope, 4, screw, 5, binding post, 6, hold-down nut, 7, high-voltage connection, 8, the seat of ascending a height.

Embodiment

As shown in Figure 1, this tool specially for attaching and detaching comprises cover body 1, fixed pulley 2, rope 3 and screw 4, at the center of the bottom surface of cover body 1 fixed pulley 2 is installed, and rope 3 passes fixed pulley 2, an end connecting screw 4 of rope 3.

During use, cover body 1 left-hand thread is on the sleeve pipe of main transformer, and with the internal thread tooth of screw 4 access binding posts 5, the other end with rope 3 holds simultaneously, just can turn round down the hold-down nut 6 on the binding post 5 relievedly; Behind the sleeve pipe of dismantling, can put down rope at leisure, at seat 8 screws of backing out on the binding post 54 suitable for reading of ascending a height, thereby can get high-voltage connection 7.

Claims
