AI Technical Summary
The existing primary and secondary integrated pole-mounted circuit breakers lack limit components, which makes it easy for staff to accidentally touch the isolating switch or operating lever during maintenance, causing accidental closing, affecting maintenance work and personal safety, and posing risks of equipment damage and line faults.
A linkage structure comprising a polygonal limit post, a limit sleeve, a rack and pinion bearing component, and a connecting rod was designed. Combined with a power mechanism of an electromagnet and a return spring, the reliable locking and precise control of the knife switch assembly are achieved through gear and rack meshing and parallelogram linkage, thus avoiding accidental closing.
It effectively avoids accidental closing caused by accidental operation of the control lever, ensures maintenance safety, improves equipment operating efficiency and reliability, adapts to the needs of automated or manual operation in different scenarios, and extends equipment life.
