Description

Insulator change device}

The present invention relates to an insulator changer, and more particularly, to an insulator replacer to easily replace the first insulator and the insulator of the insulator connected between the transmission line side and the anchor tower on the steel tower side.

In general, insulators are made of porcelain, which is used to insulate and mechanically maintain or support the spiral of transmission lines or electrical equipment.

In addition, the insulator made a large number of wrinkles to increase the distance along the surface in order to have sufficient electrical insulation strength. This is effective in preventing the insulation strength from deteriorating when the surface is wet, especially when salt or dust adheres.

In addition, as the main material of the insulator, hard magnetic is used, and it has insulation strength and is capable of having a strong mechanical force even in environments such as temperature change and sunlight without altering.

The above types of insulators include power transmission lines: suspension insulators, long insulators, and home insulators (used to withstand fouling during typhoons), distribution lines: pin insulators, and indoor wirings: knobs Insulators, pipes, cleats, circuit breakers, lightning arresters: support insulators.

On the other hand, if the insulator is damaged by lightning and other impact, it is required to replace the insulator in a state in which the tension of the transmission line is applied, and the insulator is required to be complicated and simple.

1 is a view showing a typical insulator replacement device.

As shown in FIG. 1, the insulators 10 are formed at both ends of the first and second gripping members 12 for gripping a transmission line (not shown) provided with a plurality of insulators (not shown). 14, first and second bolts 16 and 18 having one end connected to both sides of the first and second gripping members 12 and 14, and having a screw formed at the other end, and the first and second holding members 12 and 14. The first and second bolts 16 and 18 are fastened to correspond to the second holding members 12 and 14, and the first and second bolts 16 and 18 are reciprocated by the user's manipulation. It is composed of a torque wrench 20 for moving and varying the first and second holding members 12, 14 close or far.

Referring to FIG. 2, the operation of the general insulator is configured as follows.

For example, when the defective insulator installed on the power transmission line is the third, the first holding member 12 of the insulator replacement device 10 is installed on one side of the first insulator 30-1, and the second holding member 14 is placed on the third side. It is installed on one side of the insulator 30-3.

Then, in order to remove the third insulator, which is a defective one, the torque wrench 20 is turned clockwise a predetermined number of times.

At this time, the second bolt 18 is variable in position to the right.

According to the variation of the second bolt 18, the second holding member 14 is pushed to the right and in close contact with the fourth insulator 30-4 to push the fourth insulator 30-4 to the right.

Accordingly, a large space is generated between the third insulator 30-3 and the fourth insulator 30-4 so that the user's hand can move freely.

Then, the third insulator 30-3, which is the defective insulator, is gripped by hand, pressurized, and then removed.

However, if the first insulator or the last insulator is defective in the current 345kV transmission equipment, there is a problem that the defective insulator should be replaced with Cam Arong and rebar blocks because it cannot be replaced with a conventional insulator.

It takes a lot of time to transport and install the defective insulators by using Cam Along and Lever block, and to transport and install them to the work point by the size and weight of the equipment. There was a problem that deterioration and equipment damage concerns remain.

Accordingly, the present invention has been proposed to solve the above problems according to the prior art, and the object of the present invention is the connection between the anchor line on the power line side and the pylon side in the case of two conductor built-in insulator of 345kV power transmission equipment. If the first and last insulators are bad, combine the shackle clamps with the existing insulators (the insulators between the first and the last insulators are installed between the insulators and insulators) to replace the insulator and the steel tower and It is designed to connect insulators to an anchor chain, which is a connection of power lines, to provide insulators that can be replaced without the need for Kam Along and Lever Block.
