Definitions
- CN201796768U discloses a wiring switch device with an arc extinguishing device, in particular to an electric wiring switch device with a casing, a terminal connecting chamber and an arc extinguishing device, including an arc extinguishing cavity, in the arc extinguishing cavity Arranging an arc extinguishing plate stack with arc extinguishing plates stacked parallel to each other, wherein the arc extinguishing plates are spaced apart from each other in the stacking direction, and the exhaust gas flow can be from the arc extinguishing chamber at the exhaust side go away.
- the split protrusion is formed on the housing of the circuit breaker, and one end of the split protrusion contacts the tail of the arc extinguishing chamber and supports the arc extinguishing chamber.
- FIG. 1 discloses a plan view of an exhaust structure of a circuit breaker in accordance with an embodiment of the present invention.
- a first base recess 501, a second base recess 502, a third base recess 502 and a base protrusion 504 are provided on the base 105, and a base contact plate 507 is further provided.
- a first cover recess 801, a second cover recess 802, a third cover recess 802 and a cover projection 804 are provided on the cover 108, and also have a cover contact plate 807.
- the spacing between the first exhaust port 101, the second exhaust port 102, and the third exhaust port 103 is substantially equal, and is substantially half the height of the arc extinguishing chamber 106.
- the openings of the first exhaust port 101, the second exhaust port 102, and the third exhaust port 103 are all between 1.8 mm and 3 mm, and the first exhaust port 101, the second exhaust port 102, and the third row
- the size of the opening of the port 103 is generally not set to be the same, but may be set to be the same, and generally only one opening range is required to be limited.
- the first exhaust port 101, the second exhaust port 102, and the third exhaust port 103 formed on the base 105 and the cover 108 increase the number of exhaust passages while also increasing the volume of the exhaust space.
- the second exhaust port 102 is located, and the second exhaust port 102 is located at a position overlapping with the wiring device of the circuit breaker.
- Fig. 4 discloses the state of use of the wiring device according to the circuit breaker having the exhaust structure. Referring to FIG. 4, two wiring devices of the circuit breaker are disclosed in FIG. 4, which are a first wiring device 401 on the left side and a second wiring device 402 on the right side, respectively.
- the purpose of the wiring device of the circuit breaker shown is to illustrate the position of the second exhaust port 102, and is not intended to impose any restrictions on the wiring device itself.
- the exhaust space 122 corresponding to the second exhaust port 102 is overlapped with the wiring device.
- the proposed exhaust structure mainly has an exhaust port which is aligned with the tail portion of the arc extinguishing chamber, the exhaust space of the exhaust port overlaps with the wiring device of the circuit breaker, and the exhaust device occupies the exhaust when not wired. Space, the wiring space is free when the wiring device is wired.
- the invention also provides a circuit breaker having the above exhaust structure, the casing of the circuit breaker is formed with at least one exhaust port, the exhaust port is aligned with the tail portion of the arc extinguishing chamber, the exhaust space of the exhaust port and the circuit breaker The wiring devices overlap, the exhaust space is occupied when the wiring device is not wired, and the exhaust space is vacated when the wiring device is wired.
- the housing of the circuit breaker is formed with at least three exhaust ports aligned with the tail of the arc extinguishing chamber of the circuit breaker, at least three of which are equally spaced.
- the housing of the circuit breaker is formed with at least one split protrusion extending in a lateral direction from a tail portion of the arc extinguishing chamber to a position of at least one exhaust port, and the split protrusion extends from an exhaust port in a longitudinal direction To another vent adjacent to it. It should be noted that those skilled in the art can also set the number and position of the exhaust ports according to actual needs, and set or cancel the split protrusions as needed.
