AI Technical Summary
Traditional purely mechanical interlocking mechanisms in switchgear have problems such as a large number of parts, complex assembly, and easy jamming leading to incomplete action or even failure. They also cannot effectively avoid electrical safety hazards caused by misoperation.
An electromechanical interlocking scheme is adopted. Through the coordinated design of mechanical interlocking components and electrical interlocking parts, dynamic locking/releasing of the key and physical blocking/releasing of the closing operation are achieved, forming a double barrier against misoperation and ensuring precise control of equipment status and access management.
It significantly improves the safety and reliability of the switching device, avoids misoperation, simplifies the structure, eliminates the jamming risk of traditional mechanical interlocks, and achieves zero-error execution of the "three locks and two keys" logic.
