Closed Transition Transfer Switch Without Power Failure

Abstract

The present invention relates to an uninterruptible switching device. The present invention relates to a switching device that enables switching by link linking through rotational drive so that a load terminal contacts a commercial power terminal (A1) or an emergency power terminal (B1). The device comprises: a pair of rotational drive units (200) that link the respective links through the rotational operation of each provided motor so that the commercial and emergency load terminals (A1) (B1) each undergo switching operation; a switch operating unit (300) that operates the commercial and emergency load terminals (A) (B), which are linked to the rotational drive units (200) respectively, so that they standby, trip, and switch on at close positions, thereby enabling the emergency load terminal (B) to switch contact with the emergency power terminal (B1) while the commercial load terminal (A) is in contact with the commercial power terminal (A1), thereby enabling switching in an uninterrupted state; and a control unit (400) that controls the corresponding rotational drive unit (200) according to the switching signal value of the switch operating unit (300).
