Description

Technical Field

[0001] The present invention relates to the technical field of high-voltage equipment, and in particular to a structure for realizing installation and release of a (10KV) lightning protection core by using a magnet. Background Art

[0002] High-voltage fuses and high-voltage lightning arresters have always been important protective devices for protecting electrical equipment in transmission lines from lightning strikes and overvoltage damage.

[0003] High-voltage lightning arresters are limited by existing installation and tripping technologies, and can only be installed separately from the arrester and the fuse. According to this installation method, each installation location needs to be equipped with 3 sets of lightning arrester insulators, 3 sets of fuse insulators and 2 cross arms, and the cost of the required installation materials is very high. In addition, the 3 sets of lightning arresters and 3 sets of fuses must be connected separately, and finally the ground wires must be connected to the 3 sets of lightning arresters, making the installation process cumbersome. Summary of the invention

[0004] In order to solve the above technical problems, the purpose of the present invention is to provide a structure for installing and releasing a lightning protection core using magnets, thereby reducing installation costs and simplifying the installation process.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A structure for installing and releasing a lightning protection core by using a magnet is invented, comprising a solid glass fiber rod, an intermediate fixing part, a lightning protection core, a bell mouth, a lower fixing part, a magnet adsorption block, a hollow glass fiber tube and an upper fixing part;

[0007] The upper end of the lightning protection core is equipped with a demagnetization module, the top of the demagnetization module is equipped with a magnet, and the lower end of the lightning protection core is equipped with a metal conductive part;

[0008] One end of the intermediate fixing piece is inserted into the hollow glass fiber tube near the middle position along the radial direction of the hollow glass fiber tube and fixedly connected to the magnet adsorption block located in the hollow glass fiber tube, and the other end of the intermediate fixing piece is used to be fixed to the cross arm;

[0009] The upper end of the lightning protection core extends from the lower end of the hollow glass fiber tube into the interior of the hollow glass fiber tube and is magnetically connected to the magnet adsorption block through the magnet at the top thereof to complete the grounding connection, and the metal conductive part at the lower end of the lightning protection core is connected to the bell mouth to complete the high-voltage incoming line connection, and the bell mouth and the lower end fixing piece are both installed at the lower end of the hollow glass fiber tube;

[0010] The solid glass fiber rod is filled in the upper space of the hollow glass fiber tube, and the upper end of the hollow glass fiber tube is fixedly connected to the upper end fixing piece.

[0011] Furthermore, one end of the intermediate fixing piece is fixedly connected to the magnet adsorption block by means of screws.

[0012] Furthermore, the hollow glass fiber tube is provided with a reducing structure near the lower end, the outer peripheral side of the reducing structure is threaded, one end of the lower end fixing piece is sleeved on the reducing structure, and the bell mouth thread is fixed on the reducing structure and clamps the lower end fixing piece at the same time.

[0013] Furthermore, the upper end fixing piece is threadedly fixed to the upper end of the hollow glass fiber tube.

[0014] Furthermore, the upper end fixing piece is fixed to the upper end of the hollow glass fiber tube by means of screws.

[0015] Furthermore, the bell mouth is made of aluminum, and the outer surface is plated with a conductive layer.

[0016] Compared with the prior art, the beneficial technical effects of the present invention are:

[0017] The insulator that fixes the fuse is a hollow cavity inside, and the lightning core can be installed inside the cavity. A magnet is installed at the tail of the lightning core, and the attraction of the magnet can connect the entire lightning protection to the arrester system line. The lightning core is inverted inside the insulator and fixed by the magnetic force of the magnet. The upper end (magnet end) is the grounding end, and the lower end is the high-voltage incoming line end. This installation structure is used to achieve the purpose of the lightning arrester and the fuse sharing one insulator. The lightning arrester and the fuse share one insulator. The overall installation only requires 3 sets of insulators and 1 crossarm, which greatly reduces material costs. At the same time, the lightning core can complete the installation of the lightning core only by the adsorption of the magnet, so that the normal operation of the entire equipment can be achieved, and there is no need to connect other wires, simplifying the installation process.
