Interlock apparatus for three circuit breakers

An interlock apparatus configured to block an operation of a third circuit breaker while a first circuit breaker and a second circuit breaker operate, the interlock apparatus comprising:

• a first connector connected to the first circuit breaker;
• a second connector connected to the second circuit breaker;
• a central part disposed between the first connector and the second connector;
• a mover configured to be rectilinearly moved along one direction in response to the operations of the first circuit breaker and the second circuit breaker;
• a first engagement part engaged with the third circuit breaker;
• a second engagement part engaged with the central part;
• a rotator configured to be rotated around a shaft passing through the first engagement part in response to a movement of the mover;
• a base attached to the third circuit breaker;
• and
• a channel part providing a movement path of the mover and passing through the base,
• wherein the mover is rectilinearly moved along the other direction to rotate the rotator in response to a stoppage of at least one of the first circuit breaker and the second circuit breaker,
• wherein the interlock apparatus further comprises a second intermediator disposed between the third circuit breaker and the first engagement part, engaged with the first engagement part, and configured to be rotated together with the rotator,
• wherein the second intermediator comprises a stopper,
• wherein the second intermediator blocks a rotation of a first intermediator of the third circuit breaker in response to the stopper being rotated along the rotator to come into contact with an accommodation part of the first intermediator, and
• wherein the second intermediator allows the rotation of the first intermediator in response to the stopper being rotated along the rotator to be separated from the accommodation part of the first intermediator.
