Abstract
The present invention relates to an integrated interlock device of an air circuit breaker, and more particularly, to an integrated interlock device of an air circuit breaker capable of using different types of interlock devices in an integrated manner in case of using two or more air circuit breakers connected to each other, and a method of using the same.
Claims16
An integrated interlock device of an air circuit breaker, comprising:
- a mounting plate installed at part of a cradle or a switchboard;
- a bi-directional lever rotatably installed at the mounting plate, having a first arm and a second arm which are toward different directions on the basis of a first rotation shaft, and moved in a connected state to a main shaft of a circuit breaker body;
- a uni-directional lever rotatably installed at the mounting plate in a spaced state from the bi-directional lever, having a third arm which is toward one direction on the basis of a second rotation shaft, and moved in a connected state to an off lever of the circuit breaker body;
- and
- first to third cables configured to transmit a power in a connected state to the first to third arms, respectively,
- wherein each of the first to third cables includes a sheath and a core member, and
- wherein each of the first to third arms is provided with a pair of core holders for fixing a pair of core members of each of the first to third cables.

- and
- first to third cables configured to transmit a power in a connected state to the first to third arms, respectively,
- wherein a locking lever, rotated in a connected state to a shaft lever of the circuit breaker body, is provided on a rear surface of the bi-directional lever, and
- wherein a transmission lever, rotated in a connected state to the off lever of the circuit breaker body, is provided on a rear surface of the uni-directional lever.
4 more elements
A method of using an integrated interlock device of an air circuit breaker, comprising:
- connecting a first arm of a first circuit breaker with a third arm of a second circuit breaker by a first cable, connecting a second arm of the first circuit breaker with a door lever of the first circuit breaker by a second cable, connecting a third arm of the first circuit breaker with a first arm of the second circuit breaker by a third cable, connecting the second arm of the first circuit breaker with a switch lever of an MOC switch of the first circuit breaker by a fourth cable, connecting the third arm of the first circuit breaker with an opening lever of the first circuit breaker by a fifth cable, connecting a second arm of the second circuit breaker with a door lever of the second circuit breaker by a sixth cable, connecting the second arm of the second circuit breaker with a switch lever of an MOC switch of the second circuit breaker by a seventh cable, and connecting the third arm of the second circuit breaker with an opening lever of the second circuit breaker by an eighth cable;
- and
- turning on the second circuit breaker to rotate a bi-directional lever of the second circuit breaker, pulling the third cable by downward-moving the first arm of the second circuit breaker, and turning off the first circuit breaker by downward-moving the third arm of the first circuit breaker.
