Definitions
- the present invention relates to an air circuit breaker with an arc extinguishing apparatus, and more particularly, to an air circuit breaker with an arc extinguishing apparatus capable of avoiding fragments generated during an arc extinguishing process from being scattered to the exterior without filtering.
- So-called circuit breaker refers to an electric protecting apparatus which is installed between power source and load equipment in order to protect the load equipment and a line from an abnormal current (a short circuit, excess current due to an earth fault, etc.) which may be generated in an electric circuit.
- the circuit breakers may be classified, according to an arc extinguishing medium, into an oil circuit breaker (OCB), an air circuit breaker (ACB), a vacuum circuit breaker (VCB), or a gas circuit breaker (GCB).
- OOB oil circuit breaker
- ACB air circuit breaker
- VOB vacuum circuit breaker
- GCB gas circuit breaker
- the air circuit breaker may comprise fixed contact and movable contact which are installed to be in contact with or separated from each other, an opening/closing unit for opening/closing the movable contact, and an extinguishing apparatus for extinguishing arcs occurred when opening/closing the movable contact.
- Fig. 1 is an exploded perspective view showing an extinguishing apparatus for a related art air circuit breaker.
- the extinguishing apparatus for the air circuit breaker may comprise a chamber member 11 having both sides open and having an insertion groove 13 therein, a plurality of grids 21 inserted into the insertion groove 13, an insulating board 31 disposed at one side of the grids 21, a cooling board 41 disposed at one side of the insulating board 31, and an exhaust cover 51 coupled to the chamber member 11 at an outer side of the insulating board 31.
- Arc runners 25 may be disposed at both sides of the grids 21 to induce arcs occurred when contacts are separated from each other toward the grids 21.
- the insulating board 31 may be formed of an insulating material.
- a plurality of through holes 32 may be formed through a planar surface of the insulating board 31 so as to segment (disperse, distribute) arcs.
- the cooling board 41 may be formed of metal, and have a plurality of through holes 42 formed through a planar surface thereof.
- the exhaust cover 51 may have a plurality of communication holes 52 to thusly be communicated with the exterior.
- the insulating board 31 is merely disposed at the side of the downstream of the grids 21 in a direction in which gases are discharged. Accordingly, gases or fragments generated when a metal is melted are scattered to the outside without passing through the through holes 32 of the insulating board 31. As a result, the gases or fragments may then be directly discharged to the outside through the communication holes 52 of the exhaust cover 51 without first passing through the through holes 42 of the cooling board 41, the communication hole having a relatively larger size than that of the through hole of the cooling board 41.
- an object of the present invention to provide an air circuit breaker with an arc extinguishing apparatus capable of avoiding fragments generated due to arcs from being excessively scattered to the exterior.
- Another object of the present invention is to provide an air circuit breaker with an arc extinguishing apparatus capable of facilitating an arc extinguishing and avoiding fragments generated due to arcs from being excessively scattered to the exterior.
- Still another object of the present invention is to provide an air circuit breaker with an arc extinguishing apparatus capable of reducing fabrication cost and avoiding fragments generated due to arcs from being excessively scattered to the exterior
