Title:
短絡に際して離脱可能のロックシステムを有する回路遮断器の作動機構
Document Type and Number:
Japanese Patent JP4237832
Kind Code:
B2
Abstract:
The mechanism for a multi-polar circuit breaker comprises a pivoting lever system (14) associated with a release hook (44) and a switching bar (22). An opening pawl (50) co-operates with the hook to ensure the arming and release of the mechanism (10) in the locked and released positions of the pawl respectively. The opening pawl (50) comprises a releasable operating device, provoking the automatic unlocking of the bolt (60) in the presence of a short-circuit current exceeding a calibrated threshold. The threshold is defines by a spring mechanism (74,76). The automatic unlocking is controlled by the mechanical reaction generated by the electrodynamic compensation effect. This provokes an ultra-rapid rotation of the bolt to release the opening pawl (50) before the intervention of the release device (70).
