Embodiment 1

[0051]Seefigure 1 , The present invention provides a recoil extinguishing device, comprising an arc ignition assembly 1, a recoil assembly 2, an air-termination assembly 3 and a lightning rod 4. The arc ignition assembly 1 is arranged at one end of the recoil assembly 2 and the ignition An arc guide ring 11 is arranged between the arc assembly 1 and the recoil assembly 2, the air-termination assembly 3 is arranged at the other end of the recoil assembly 2, and one end of the lightning rod 4 is fixed on the air-termination assembly 3. The recoil arc extinguishing device can be installed on any existing lightning rod or lightning protection device to form a lightning protection device with recoil effect.

[0052]The air-termination component 3 is arranged in a conical structure, a hemispherical structure, a truncated cone structure, or a number of conical structures are fixed at the bottom of the circular plate, and the air-termination component 3 is made of conductive materials. The abo...

Embodiment 2

[0055]Such asPicture 11 As shown, the structure includes two above-mentioned recoil arc extinguishing devices and a flashback recoil assembly 5, and the lightning recoil assembly 5 is arranged between the two recoil arc extinguishing devices. This application is not limited to the two recoil extinguishing devices mentioned above. Multiple recoil extinguishing devices are also possible, and can be set as required. A flashback recoil assembly 5 is arranged between the two recoil extinguishing devices to form multiple The recoil function of the first stage makes the arc cutting effect better. Among them, the combination of the recoil extinguishing device and the flashback recoil assembly 5 is the content of the application that needs to be publicly protected, for example, two recoil extinguishing devices are directly connected, etc., or two flashback recoil devices are provided. Various structures such as the component 5 together are the protection content of the actual invention and c...

Embodiment 3

[0058]The recoil assembly 2 includes a recoil tube 21 and a plurality of arc-climbing edges 22. The recoil tube 21 has a hollow structure in the middle, and the plurality of arc-climbing edges 22 are fixedly arranged on the outside of the recoil tube 21.

[0059]The recoil tube 21 is made of high-strength, high-temperature and high-pressure resistant non-conductive materials. The high-strength, high-temperature and high-pressure resistant non-conductive materials use alloy ceramics, rare earth ceramics, graphene-ceramic composite materials, organic ceramics, synthetic silicone rubber, and organic Any one of insulating material, alloy glass, rare earth glass, graphene glass, and organic glass. The use of the above-mentioned materials has the characteristics of high arc extinguishing threshold, and is made of high-strength, high-temperature and high-pressure resistant non-conductive materials, so that the burning temperature is higher.

[0060]The radii of the several circular climbing arc ...

Abstract

The invention discloses a recoil arc extinguishing device and a lightning rod, and belongs to the technical field of lightning protection and arc extinguishing, the recoil arc extinguishing device comprises an arc striking assembly, a recoil assembly, a lightning receiving assembly and a lightning striking rod, the arc striking assembly is arranged at one end of the recoil assembly, and an arc guide ring is arranged between the arc striking assembly and the recoil assembly; and the lightning receiving assembly is arranged at the other end of the recoil assembly, and one end of the lightning leading rod is fixed to the lightning receiving assembly. According to the invention, electronic equipment and buildings of the transformer substation are effectively protected, and the safety of a power system is ensured. The device protects buildings, residential buildings and airports, reduces electromagnetic induction interference in the aspect of communication, and does not influence communication signals. The probability of occurrence of various short circuits in a power system is greatly reduced, and the probability of causing malignant accidents is greatly reduced.

Description

Technical field[0001]The invention relates to the technical field of lightning protection and arc extinguishing, in particular to a recoil arc extinguishing device and a lightning rod.Background technique[0002]Lightning is a gas discharge phenomenon in nature. It will endanger the lives of humans and animals and destroy various buildings. We need to set up protective devices to avoid or reduce the damage caused by lightning. We use lightning rods to protect buildings and tall trees from lightning strikes. The role of lightning rods is to attract lightning strikes to themselves, and the lightning current is quickly discharged into the earth through the grounding device. However, there are still some disadvantages of lightning rods.[0003]1. The discharge process of the lightning rod has a greater impact:[0004]When lightning strikes, ordinary lightning rods can to a certain extent prevent damage to buildings or transmission lines caused by lightning strikes, and protect the safety of b...
