Fixed connecting structure and method for conductor and insulator supporting conductor

Abstract

The invention provides a fixed connecting structure and a method for a conductor and an insulator supporting the conductor. First grooves are formed in the inner concave part of the outer wall of theconductor. The insulator is integrally formed outside a barrel body in a pouring manner, and the insulator sleeves the conductor. Second grooves and chutes connected to the second grooves are formed in the inner concave part of the inner wall of the barrel body. A first limiting key is embedded in the first groove and the second groove. A second limiting key is embedded in the chute, and the second limiting key is fixedly arranged between the first limiting key and the side wall of the chute. According to embodiments of the fixed connecting structure and method for the conductor and the insulator supporting the conductor, fixed connection between the conductor and the insulator supporting the conductor can be realized in an ultra-clean, normal temperature, light and low-cost manner.

Description

technical field [0001] The invention relates to the technical field of high-voltage electrical switchgear, in particular to a fixed connection structure and method for a conductor and an insulator supporting the conductor. Background technique [0002] The statements in this section only provide background information related to the present disclosure and may not constitute prior art. [0003] In the case of GIL or GIS busbar applications, a standard assembly unit for installation and disassembly usually includes a tubular shell container containing insulating medium gas. A metal tubular conductor is coaxially arranged in the shell container. The shell container and The conductors are provided with supporting insulators. No matter how the structural shape of the insulator changes, the supporting insulator and the conductor must achieve a fixed connection effect in the axial and circumferential directions. [0004] There are many existing technologies and embodiments for th...

Problems solved by technology

If the plastic deformation of the metal cylinder is too large, it will cause a large internal stress in the insulator, which will affect the bonding strength between the insulator and the metal cylinder

If the plastic deformation of the metal cylinder is too little, the connection strength between the metal cylinder and the conductor will be insufficient, and it will be difficult to ensure the fixed connection strength between the insulator and the conductor

[0023] In addition, during the process of wedging the metal wedge between the metal cylinder and the outer wall of the conductor, metal scraps will be generated

If these metal scraps are not cleaned thoroughly, discharge flashover may occur in the subsequent use process, which will bring hidden dangers to the quality of the product

[0024] In short, using the technical solution of the known embodiment 4, there are defects that it is difficult to grasp the strength of the fixed connection, and it is difficult to completely remove metal scraps
