Abstract
An interlock structure of a bypass transfer switching device is proposed. When supply power is bypassed through a bypass switch, a lever input portion is closed to prevent manual switching of an automatic transfer switch, and when the automatic transfer switch is drawn from a switchboard, the closed lever input portion is automatically opened. The interlock structure includes: the automatic transfer switch having the lever input portion of a through hole shape for the manual switching of a normal supply and an alternative supply; the bypass switch configured to bypass electric power of the normal supply or the alternative supply supplied to a load side through the automatic transfer switch, the bypass switch including a bypass lever capable of manually changing a bypass circuit; and an interlock device configured to automatically close the lever input portion when the bypass lever is operated.
