Abstract

The application provides a wall bushing and a preparation method thereof. The wall bushing comprises a first end cover, a conducting bar, a second end cover, porcelain pieces and a flange. The wall bushing further comprises conductive coatings, buckles and conductive gaskets. The conductive coatings coat the outer surfaces of a first conductive zone and a second conductive zone, and the first conductive zone and the second conductive zone are the porcelain pieces between the flange and adjacent umbrella skirts. The conductive gaskets are attached to the outer surfaces of the conductive coatings respectively. The buckles are arranged outside the conductive gaskets respectively, and fasten the conductive gaskets outside the conductive coatings respectively. By using the wall bushing providedby the application, the problem that the existing wall bushing has a poor insulation effect can be solved.

Description

technical field [0001] The present application relates to the technical field of electricity safety in power systems, in particular to a wall-piercing bushing and a preparation method thereof. Background technique [0002] Wall bushing is an important component of high-voltage switchgear and is widely used in power systems. Wall bushings are suitable for power distribution devices and high-voltage electrical appliances in substations, and are used as insulation and support for conductive parts to pass through walls or other grounding objects. [0003] In recent years, a large number of faults of wall bushings have occurred in various power grid companies. Among them, the insulation faults of wall bushings with discharge as the main form account for the vast majority of wall bushing faults, and the consequences of insulation failures are often More serious. It can be seen that avoiding the occurrence of insulation faults is the key to ensuring the stable operation of wall b...
