Abstract

The invention discloses a multi-protection interlocking mechanism for an inflatable cabinet, which belongs to the technical field of switch cabinets and comprises a cabinet body, an operation panel, an interlocking mechanism and a cabinet door. A load switch operating shaft rotates, and the interlocking mechanism drives a grounding switch shielding plate to keep away from or shield the grounding switch operating shaft. The grounding switch operating shaft rotates, and the load switch shielding plate is driven by the interlocking mechanism to avoid or shield the load switch operating shaft; andthe operation panel is provided with a load switch operation hole and a grounding switch operation hole, and the operation panel is provided with a shielding lock catch assembly for shielding or avoiding the load switch operation hole and the grounding switch operation hole. The shielding lock catch assembly shields or avoids the load switch operation hole and the grounding switch operation hole,achieves two-layer protection, guarantees the operation reliability and safety of the gas insulated switchgear, and effectively avoids the problems of frequent faults and even personal and equipmentsafety accidents. The structure is simple, operation is convenient, and implementation is easy.

Description

technical field [0001] The invention belongs to the technical field of switch cabinets, in particular to a multi-protection interlocking mechanism for an inflatable cabinet. Background technique [0002] The SF6 inflatable cabinet is a fully sealed system, all moving parts and switches are sealed in a stainless steel casing. The entire switchgear is not affected by external conditions, and can ensure the reliability of operation and personal safety. With the rapid development of my country's urban modernization and the continuous upgrading of urban and rural power grids, SF6 inflatable tanks have a very wide range of applications. [0003] With the large number of applications of SF6 inflatable cabinets, especially the long-term operation time and the early interlocking products, there are often jamming and falling off of the interlocking shaft, and the unreliable interlocking leads to frequent failures. There are strict operating procedures for SF6 inflatable cabinets. Wh...
