Abstract
A novel arc extinguish chamber is disclosed to mainly solve the problem that arc strike of a present arc extinguish chamber is not smooth, arc strike speed is slow and arc scatters in all directions. The novel arc extinguish chamber is characterized in that an arc strike sheet is provided with several arc strike holes which are configured in a triangle array. By the adoption of the novel arc extinguish chamber, arc strike speed is fast, arc strike is smooth, arc will not scatter in all directions, and service life of the mechanism is prolonged.
Description
Technical field
The utility model relates to a kind of circuit breaker, is specifically related to a kind of novel arc control device.
Background technology
Circuit breaker is a kind of existing hand switch effect, can transship automatically again and the electrical equipment of short-circuit protection.It can be used to distribute electric energy; do not start asynchronous motor continually; power circuit and motor etc. are carried out protection, can automatic shutdown circuit when serious overload or short circuit and fault such as under-voltage take place for their, its function is equivalent to Fuse switch and the combination of crossing underheat relay etc.And behind the disjunction fault current, generally do not need to change parts, therefore obtained to use widely.
Existing miniature circuit breaker generally adopts grid sheet arc extinguishing technology.U-shaped or the V-type grid sheet that arc control device are made by ferromagnetic material and assembled by the flash barrier that insulating material is made.When miniature circuit breaker divides deenergizing to produce electric arc, because the existence of grid sheet, the magnetic flux path that arc current produces in the air around distorts, magnetized grid sheet produces electromagnetic force electric arc is pulled to arc control device, to the cutting apart and cool off of electric arc, arc resistance increases, and is that arc voltage improves by the grid sheet, when arc voltage reached certain value, electric arc was extinguished.And make a general survey of in the market circuit breaker, and all exist the smooth and slow-paced problem of striking of high-temperature electric arc striking, when dynamic and static contact disjunction short circuit current, the phenomenon that the generation high-temperature electric arc scatters and flies has seriously influenced useful life of circuit breaker.
The utility model content
In order to overcome disadvantages of background technology, the utility model provides a kind of novel arc control device, and it is not smooth mainly to have solved existing arc control device striking, and striking speed is slow, the problem that electric arc scatters and flies.
The technical scheme that the utility model adopts is: a kind of novel arc control device, comprise housing, described housing is made of flash barrier, be provided with arc extinguishing grid pieces in the described housing, be extended with the striking sheet on the described housing, described striking sheet is provided with some strikings hole, and described striking hole array-like triangular in shape is arranged.
Described flash barrier is provided with some coolings hole.
Described housing is provided with blocked hole, and described striking sheet is connected on the housing by blocked hole.
The beneficial effects of the utility model are: striking speed is fast, and the striking smoothness can not produce the phenomenon that electric arc scatters and flies, and has prolonged the useful life of mechanism.
Description of drawings
Fig. 1 is front view of the present utility model.
Fig. 2 is left view of the present utility model.
1-housing among the figure, 11-flash barrier, the 111-hole that lowers the temperature, 2-arc extinguishing grid pieces, 3-striking sheet, 31-striking hole, 4-blocked hole.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described further:
As Fig. 1 in conjunction with shown in Figure 2, a kind of novel arc control device, comprise housing 1, described housing 1 is made of flash barrier 11, be provided with arc extinguishing grid pieces 2 in the described housing 1, be extended with striking sheet 3 on the described housing 1, described striking sheet 3 is provided with some strikings hole 31, and described striking hole 31 array-likes triangular in shape are arranged.
Described flash barrier 11 is provided with some coolings hole 111.
Described housing 1 is provided with blocked hole 4, and described striking sheet 3 is connected on the housing 1 by blocked hole 4.
The concrete use of the utility model is as follows: when moving contact separates with fixed contact, produce electric arc, electric arc converges in the middle of striking sheet 3 under the effect in striking hole 31 on the striking sheet 3, fast, stably guides electric arc into arc control device, and electric arc can not scatter and fly.
The beneficial effect of utility model is: striking speed is fast, and the striking smoothness can not produce the phenomenon that electric arc scatters and flies, and has prolonged the useful life of mechanism.
