Abstract
An interlock structure of a bypass transfer switching device is proposed. When supply power is bypassed through a bypass switch, the interlock structure may prevent manual switching on an automatic transfer switch, and allow the automatic transfer switch to be input into a switchboard when power input directions of the bypass switch and the automatic transfer switch match with each other. The interlock structure includes: the automatic transfer switch having a lever input portion for 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; and an interlock device configured to automatically close the lever input portion when the bypass lever is operated.
