Interlock module, circuit breaker movement unit and switchboard comprising same
The present disclosure relates to an interlock module, a circuit breaker movement unit and a switchboard comprising same. Provided is the interlock module comprising: an outer case in which an interlock guide pin is moveable along the top surface thereof and a plurality of grooves are formed on the top surface to enable insertion of the interlock guide pin; a guide plate which is arranged inside the outer case, and which moves to the rear surface of the outer case if a handle is inserted into a handle insertion hole; and a link plate which is connected to the guide plate, and which moves toward the top surface of the outer case when the guide plate moves to the rear surface of the outer case, wherein the link plate enables the interlock guide pin to move at a height greater than or equal to that of the top surface of the outer case when moving toward the top surface of the outer case.
1 . An interlock module comprising:
an outer case having an upper surface on which an interlock guide pin is movable, and including a plurality of grooves formed in the upper surface such that the interlock guide pin is inserted;
a guide plate disposed inside the outer case and moved toward a rear surface of the outer case when a handle is inserted into a handle insertion opening; and
a link plate connected to the guide plate and moved toward the upper surface of the outer case when the guide plate is moved toward the rear surface of the outer case,
wherein the interlock guide pin is movable at a height equal to or higher than that of the upper surface of the outer case when the link plate is moved toward the upper surface of the outer case.
2 . The interlock module of claim 1 , wherein the link plate presses the interlock guide pin upward such that the interlock guide pin is adjacent to the height of the upper surface of the outer case upon the insertion of the handle in a case where the interlock guide pin is inserted into one of the plurality of grooves of the outer case.
3 . The interlock module of claim 2 , further comprising a link member connected to each of the guide plate and the link plate to allow conversion between forward and backward movement of the guide plate and vertical movement of the link plate.
4 . The interlock module of claim 3 , wherein the link member comprises:
a first portion connected to the guide plate; and
a second portion bent and extending from the first portion and connected to the link plate.
5 . The interlock module of claim 4 , wherein the first portion and the second portion of the link member are disposed to form an angle of 60 degrees to 120 degrees with each other.
6 . The interlock module of claim 5 , wherein the outer case has a guide hole into which a coupling member coupled to the link member is inserted,
the link member further comprises a coupling member disposed inside the outer case to fix the link member to the link member guide hole, and
the link member is moved along the link member guide hole.
7 . The interlock module of claim 6 , wherein the outer case comprises a guide plate guide hole into which a coupling member coupled to the guide plate is inserted, and
the guide plate is disposed inside the outer case to be moved along the guide plate guide hole.
8 . The interlock module of claim 7 , wherein the link member guide hole has a shape of at least a portion of a circumference, and the guide plate guide hole has a linear shape.
9 . The interlock module of claim 3 , wherein the outer case further comprises a stopper protruding inward to lock the guide plate in a moving direction of the guide plate when the guide plate moves in a back-and-forth direction.
10 . The interlock module of claim 9 , wherein the guide plate is formed along a longitudinal direction of the outer case, and
the guide plate further comprises a guide part disposed on one end thereof opposite to the handle insertion opening into which the handle is inserted, and covering at least one of the plurality of grooves of the outer case.
11 . A circuit breaker movement unit comprising:
a cradle on which a circuit breaker is mounted;
an interlock module disposed on a front surface of the cradle to allow movement of the circuit breaker after a handle is inserted; and
an interlock guide pin pressing an outer case of the interlock module downward,
wherein the interlock module comprises:
the outer case having an upper surface on which the interlock guide pin is movable and including a plurality of grooves formed in the upper surface such that the interlock guide pin is inserted;
a guide plate disposed inside the outer case and moved toward a rear surface of the outer case when the handle is inserted into a handle insertion opening; and
a link plate connected to the guide plate and moved toward the upper surface of the outer case when the guide plate is moved toward the rear surface of the outer case, and
wherein the interlock guide pin is moved by the link plate to be movable at a height equal to or higher than that of the upper surface of the outer case.
12 . A switchboard comprising:
a switchboard case having an inner space;
a circuit breaker drawn into the switchboard case; and
a circuit breaker movement unit configured to move the circuit breaker to a closing position, a test position, and a run position inside the switchboard case,
wherein the circuit breaker movement unit comprises:
a cradle on which the circuit breaker is mounted;
an interlock module disposed on a front surface of the cradle to allow movement of the circuit breaker after a handle is inserted; and
an interlock guide pin pressing an outer case of the interlock module downward,
wherein the interlock module comprises:
the outer case having an upper surface on which the interlock guide pin is movable and including a plurality of grooves formed in the upper surface such that the interlock guide pin is inserted;
a guide plate disposed inside the outer case and moved toward a rear surface of the outer case when the handle is inserted into a handle insertion opening; and
a link plate connected to the guide plate and moved toward the upper surface of the outer case when the guide plate is moved toward the rear surface of the outer case,
wherein the interlock guide pin is moved by the link plate to be movable at a height equal to or higher than that of the upper surface of the outer case.
