Abstract

The invention discloses a wall-through sleeve for high-voltage power switch equipment. The wall-through sleeve comprises a wall-through sleeve body, wherein an installation flange is arranged at a middle part of the wall-through sleeve body, brass embedment pieces embedded to the circumference of the installation flange, threaded holes are formed in the brass embedment pieces, umbrella skits are uniformly arranged on an outer wall of the wall-through sleeve body along an axial direction of the wall-through sleeve body, the tops of the umbrella skits are arc, two abutting parts are arranged onan inner wall of the wall-through sleeve body and are symmetrically arranged, installation holes are formed in the abutting parts, and opening directions of the installation holes are parallel to theaxial directions of the wall-through sleeve body. In the wall-through sleeve, the abutting parts are arranged on inner walls of the wall-through sleeve body, a conductive piece support plate can be connected to the abutting parts via a bolt, a middle part of the conductive piece support plate can be made according to the shape and the size of a conductive piece of the high-voltage switch equipmentin a special model, installation demand can be achieved only by replacing the conductive piece support plate during application, and the production and management cost is reduced.

Description

Technical field [0001] The invention relates to the technical field of power switch equipment, in particular to a wall bushing for high-voltage power switch equipment. Background technique [0002] Wall-through casing is also called wall-through pipe, waterproof casing, wall pre-embedded pipe, and waterproof casing is divided into rigid waterproof casing and flexible waterproof casing. The two are mainly used in different places. Flexible waterproof casing is mainly used in places with high requirements such as air defense walls and pools. Rigid waterproof casing is generally used in basements and other places where pipes need to pass through. [0003] The high-voltage wall bushing is suitable for power distribution devices and high-voltage electrical appliances in power plants and substations with a power frequency AC voltage of 35kV and below. It is used as insulation and support for conducting parts through walls or other grounding objects. The casing is suitable for the ambien...
