Description

Porcelain bushing lightning arrester

Technical Field

The utility model relates to the technical field of lightning arresters, in particular to a porcelain bushing lightning arrester.

Background

Porcelain bushing arresters are a type of electrical equipment used to protect buildings, equipment and personnel. It is usually made of porcelain material, has good insulating properties and durability, and can effectively receive and disperse lightning current, and protect equipment from damage. Porcelain bushing arresters are commonly installed on roofs of buildings, overhead equipment, power lines, and the like, in locations susceptible to lightning strikes. When lightning hits a building or equipment, the porcelain bushing lightning arrester can rapidly guide current to the ground, so that damage of overvoltage to the equipment is avoided, and life safety of personnel is protected.

Porcelain bushing arresters are typically composed of one or more electroceramic shells. Under normal conditions, the porcelain bushing arrester is in a high voltage state, short-circuiting the overvoltage to ground. When the system is struck by lightning or overvoltage occurs, the porcelain bushing lightning arrester can be conducted rapidly, and the overvoltage is shorted to the ground through the shell.

However, when the existing porcelain bushing lightning arrester is installed on the roof of a building, the existing porcelain bushing lightning arrester is generally connected through screw threads, but the connecting part is always exposed to the outside and rusts after the porcelain bushing lightning arrester is blown by wind, rain and sun for a long time, so that certain trouble is brought to the subsequent overhaul and disassembly; in view of this, we propose a porcelain bushing arrester.
