一种直插机械式空开辅助接点抖动指示器
By designing a direct-insertion mechanical circuit breaker auxiliary contact jitter indicator, a magnetic coil and spring structure are used to capture and lock the instantaneous jitter of the circuit breaker auxiliary contact. This solves the problem of difficulty in capturing and locating jitter signals in existing technologies, realizes reliable fault branch location and early warning, and reduces systemic risks.

AI Technical Summary
Existing technology cannot effectively capture the instantaneous jitter signal of the auxiliary contacts of the air switch in the parallel branch, causing the abnormal information to disappear immediately after recovery. This makes it difficult to detect potential hidden dangers in the parallel system in a timely manner when a fault occurs, and there is a lack of evidence for post-incident investigation, which poses a risk of unplanned downtime.
Design a direct-plug mechanical circuit breaker auxiliary contact jitter indicator. Utilize a magnetic coil and spring structure to trigger the switching of the indicator window state at the moment of contact jitter, and maintain the abnormal state mark through the mechanical interference of the reset lever, providing continuous physical positioning basis.
It achieves reliable capture and status locking of instantaneous jitter, provides visualized fault branch location, shortens fault investigation time, blocks the accumulation path of hidden dangers, and reduces the probability of unplanned downtime.
