Mechanically operated cell switch of vacuum circuit breaker

摘要

There is provided a mechanically operated cell (MOC) switch of a vacuum circuit breaker, which is uniformly operated regardless of an insertion stroke of a push rod that operates a MOC switch of a vacuum circuit breaker. The MOC switch outputting an ON/OFF state of a vacuum circuit breaker when the vacuum circuit breaker operates includes: a main bracket (10); a rotational shaft (20)installed in the main bracket (10); a connection lever (30) rotatably coupled to the rotational shaft (20) and having one end (31) connected to an auxiliary switch (80); a roller (35) coupled to the other end (32) of the connection lever (30); and a horizontal moving unit installed in a portion of the main bracket and making a horizontal movement to rotate the roller (35) and allowing the other end of the connection lever (30) to make an ascending and descending movement.
