AI Technical Summary
The existing vacuum interrupter support structure of environmentally friendly gas ring main units has problems such as poor insulation performance, uneven electric field distribution and difficulty in miniaturization. In addition, traditional casting and clamp fixing schemes have defects such as large weight, easy damage and difficulty in repair.
The design employs an assembly of insulating cylinders and insulating beams, with movable fixing achieved through connectors. Combined with the cooperation of heat dissipation channels and limit nuts, it ensures stable installation and insulation performance of the vacuum interrupter, and optimizes the electric field distribution.
It improves insulation performance and the uniformity of electric field distribution, making it suitable for use in environmentally friendly gas cabinets. It enables a compact design, reduces costs, and increases production efficiency.

Abstract
Claims
1. An assembled vacuum interrupter mounting support module, characterized by: Includes insulating cylinders and insulating beams; There are three insulating cylinders in total, arranged in a straight line on the insulating beam, and the insulating cylinders are movably fixed to the insulating beam through the cooperation of connectors; An insert is provided at the bottom of the insulating cylinder, and a vacuum interrupter is installed inside the insulating cylinder. The vacuum interrupter is fixed to the insert by a limiting nut. A flexible connector and a flexible connector gasket are provided at the top of the insulating cylinder, and the flexible connector and the flexible connector gasket are fixed to the top of the vacuum interrupter by a fastening bolt.
2. The assembled vacuum interrupter mounting support module of claim 1, wherein: The insulating cylinder, insulating beam, and connector are configured as follows: The insulating beam has a through hole for the insulating cylinder to pass through vertically. This through hole is a stepped through hole, consisting of an upper stepped hole and a lower stepped hole, with the upper stepped hole being larger than the lower stepped hole. The outer wall of the insulating cylinder fits against the inner wall of the lower stepped hole. A ring-shaped fixing ring is integrally formed on the outer wall of the insulating cylinder, with its outer wall fitting against the inner wall of the upper stepped hole. The connector is a connecting bolt, which passes through the fixing ring and is threaded onto the insulating beam, thus achieving the fixation between the insulating cylinder and the insulating beam.
3. The assembled vacuum interrupter mounting support module of claim 1, wherein: The insulating cylinder is also provided with heat dissipation channels. There are several heat dissipation channels, which are vertically distributed along the circumference of the insulating cylinder and run through the entire insulating cylinder from top to bottom. Each heat dissipation channel is located on the outside of the vacuum interrupter.
