Overlapping and separating mechanism of isolating switch, operating mechanism and isolating switch

The invention discloses a lapping and separating mechanism of an isolating switch, which at least comprises a metal elastic piece and a metal limiting piece, the metal elastic piece is a sheet-shaped curved-surface structure with a hollow middle part and is provided with an opening, the metal limiting piece is provided with a force arm, and the opening of the metal elastic piece movably enters the force arm to form lapping; when the isolating switch receives a remote control opening signal, the tripping reaction and action are quicker, a power supply can be quickly cut off, and the reliability of the isolating switch and the safety of system operation are improved. 本发明公开一种隔离开关的搭接和脱离机构，至少包括金属弹性件、金属限位件，所述金属弹性件为片状、曲面、中间呈空心状结构且设置有开口，所述金属限位件设置有力臂，所述金属弹性件的开口运动地进入所述力臂上形成搭接；所述金属限位件的力臂运动地从所述金属弹性件的开口中脱离，本发明的隔离开关在接收到远程控制分闸信号时，脱扣反应及动作更快速，能够迅速切断电源，提高了隔离开关的可靠性及系统运行的安全性。
