SWITCH DEVICE AND SWITCH DEVICE OPERATION MECHANISM

摘要

A switchgear operating mechanism has: a ratchet wheel (22) that rotates together with a closing shaft (3); a stop lever (21) that enables contact between an energy storing cam (29) and a roller (28); a motor (7) that transmits power to a feed lever (20); a feed pawl (23); stop pawls (24a), (24b) that suppresses reverse rotation of the feed pawl (23); a closing lever (10) that expands/contracts a closing spring (1); a catch mechanism (11) for energy storage for the closing lever (10); a closing cam (14); a stopper unit (41) that suppresses rotation of the stop lever (21); a first sprocket (7b); second and third sprockets (7d), (7f) that are capable of rotating together with an intermediate shaft (7e); a fourth sprocket (7h) rotatably fastened to an energy storing cam shaft (29a); a first chain (7c) that engages with the first and second sprockets (7b), (7d); and a second chain (7g) that engages with the third and fourth sprockets (7f), (7h).
