AI Technical Summary

Technical Problem

The side of the inflatable cabinet is uneven due to welding, resulting in uneven splicing and assembly. In the event of arcing and other accidents, the cable door is prone to deformation, which poses safety hazards.

Method used

A well-safe inflatable cabinet is designed, which avoids the weld protrusion by providing support components and avoiding grooves at the front end of the side panel of the air box; and a barrier strip and a baffle are provided at the cable room door to form a paper-shaped structure to enhance strength and safety.

Benefits of technology

The flatness of the sides of the inflatable cabinet is improved, ensuring accurate installation dimensions and reducing cabinet assembly failures; by enhancing the strength and structure of the cable room door, avoiding arc spraying, the safety of the inflatable cabinet is significantly improved.

Abstract

The utility model provides a gas-insulated switchgear with good safety, which comprises a gas-insulated switchgear body, a switch gas box arranged at the rear part of the gas-insulated switchgear body, an operation chamber arranged at the top of the front end of the gas-insulated switchgear body, a cable chamber arranged at the bottom of the front end of the gas-insulated switchgear body, a first operation chamber door and a second operation chamber door arranged at the front end of the operation chamber, and a baffle plate arranged inwards along the edge of the operation chamber, the front end of the cable chamber is provided with a cable chamber door, the cable chamber door is provided with a barrier strip inwards along the edge, the two sides of the switch gas tank are provided with gas tank side plates, the front ends of the gas tank side plates are provided with supporting assemblies, and the side edges, close to the gas tank side plates, of the supporting assemblies are provided with avoiding grooves. The groove type supporting assembly is adopted to avoid welding seam protrusions of the side plate of the gas tank, and it is ensured that the installation size of the switchgear is accurate. Through the arrangement of the baffle plate and the barrier strip, a corridor type structure is realized, a double-layer door structure is adopted, smooth pressure relief can be ensured when major accidents such as arcing occur in the gas-insulated switchgear body, arc light injection is shielded through the corridor type structure, and protection for operators is ensured.
