Lightning arrester assembly with corrosion-resistant structure

Abstract

The utility model relates to the technical field of high-voltage power transmission lines, specifically to a lightning arrester assembly with an anti-corrosion structure, including an insulating bracket, a metal bracket is installed on the outer side of the insulating bracket by threading, an arrester housing is arranged on the inner side of the insulating bracket, a connecting shell is arranged at the lower end of the arrester housing, and a sealing gasket is arranged between the arrester housing and the connecting shell. The improved arrester assembly is provided with a sealing gasket. Since the upper and lower ends of the arrester housing are provided with sealing gaskets, if there is extreme rainstorm weather, the sealing gasket can be used to prevent rainwater from entering. At the same time, the sealing gasket is made of polytetrafluoroethylene material, which can cope with more extreme environments. It adopts a split design. If the internal arrester core fails, it can be quickly replaced. Since the arrester is often in a high position, it is more dangerous for the staff to install it, so only the faulty parts need to be carried, and do not carry too much to protect the lives of the staff.

Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage power transmission lines, in particular to a lightning arrester component with an anti-corrosion structure. Background Art

[0002] A lightning arrester is a device used to protect power systems and electrical equipment from lightning strikes and overvoltage. It can quickly direct the current caused by lightning strikes or overvoltage to the ground or other safe paths to protect the safe operation of equipment and systems.

[0003] The arrester assembly generally refers to the parts that make up the arrester, such as (housing, connectors and insulators, etc.). The existing arrester assembly does not consider the problem of corrosion protection during installation. At the same time, the overall structure is an integrated structure. During the replacement process, the entire assembly needs to be replaced together, which has poor practicality.

[0004] In the process of realizing the utility model, the inventors found that the prior art had the following problems: 1. During the installation process of the existing lightning arrester assembly, the connection parts are not sealed. When encountering extreme rainstorm weather, rainwater will penetrate into the interior, causing the internal resistor to malfunction and the internal connection to be corroded; 2. During the maintenance process of the existing lightning arrester assembly, the entire variable resistor needs to be replaced, which takes a long time and wastes time, and has poor practicality. Utility Model Content

[0005] The purpose of the utility model is to provide an arrester assembly with an anti-corrosion structure to solve the problems raised in the above background technology. To achieve the above purpose, the utility model provides the following technical solutions: an arrester assembly with an anti-corrosion structure, comprising an insulating bracket, a metal bracket is threadedly installed on the outer side of the insulating bracket, an arrester housing is arranged on the inner side of the insulating bracket, a connecting shell is arranged at the lower end of the arrester housing, a sealing gasket 1 is arranged between the arrester housing and the connecting shell, an upper top cover is arranged at the upper end of the arrester housing, a sealing gasket 2 is arranged between the arrester housing and the upper top cover, an arrester core is arranged inside the arrester housing, a fixing nut is arranged at the upper end of the upper top cover, and a disconnector is arranged at the lower end of the insulating bracket.

[0006] Further preferably, the insulating bracket and the metal bracket together form an "L"-shaped structure, and the insulating bracket and the connecting shell are adapted to each other.

[0009] Further preferably, the threaded column 1 passes through the insulating bracket and extends to the interior of the disconnector, and the threaded column 1 is a threaded connection.

[0010] Further preferably, the second threaded column passes through the upper cover and extends to the upper end of the upper cover, and the second threaded column and the fixing nut are threadedly connected.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] In the utility model, a sealing gasket is provided. Since the sealing gaskets are provided at both the upper and lower ends of the arrester housing, if extreme rainstorm weather occurs, the sealing gaskets can prevent rainwater from entering. At the same time, the sealing gasket is made of polytetrafluoroethylene material and can cope with more extreme environments.

[0013] In the utility model, a split design is adopted. If the internal arrester core fails, it can be quickly replaced.

At the same time, the insulating bracket 1 and the connecting shell 4 are adapted to each other, and after the lightning arrester is installed, it can be more stable and not easy to fall off.

At the same time, the sealing gasket 1 5 and the sealing gasket 2 7 are made of polytetrafluoroethylene material, which is a material with excellent chemical stability and high temperature resistance, and provides corrosion protection for the internal arrester core 8.

The core 8 provides an anti-corrosion function, and the base 801 and the top cap 804 are connected by the outer glass fiber strip 806 to prevent the variable resistor 802 from falling. The base 801, the variable resistor 802 and the top cap 804 are completely pressed together. Since the threaded column 803 penetrates the insulating bracket 1 and extends to the interior of the disconnector 10, and the threaded column 803 is a threaded connection, the disconnector 10 is aligned with the threaded column 803 and screwed in, so that the threaded column 803 completely enters the interior of the disconnector 10, and the lightning arrester is fastened to the insulating bracket 1. Since the fixing nut 9 has two nuts, a gasket can be placed between the two nuts, so that the current can be transmitted to the lightning arrester core 8 through the threaded column 805.
