Abstract
An arc-extinguishing chamber of a universal circuit breaker mainly solves the problem that the conventional arc-extinguishing chamber of a universal circuit breaker has poor arc extinguishing effect so as to influence the breaking capability, and is characterized in that V-shaped arc striking corners are arranged at one of the two ends of arc extinguishing grid pieces (1) in the positions corresponding to movable contacts (8); the two sides of each arc striking corner take the shape of evolutes; and the arc striking corners of adjacent arc extinguishing grid pieces (1) are staggered in a concave-convex to form a labyrinth structure. The arc-extinguishing chamber of the universal circuit breaker adopts the arc extinguishing grid pieces with labyrinth structures and is additionally provided with arc baffle plates, so that arcs can be quickly elongated, cooled and extinguished, and higher breaking capability is achieved; and meanwhile, the arc cannot escape out of the arc-extinguishing chamber, so that zero flashover can be realized.
Description
Technical field
The utility model relates to a kind of omnipotent breaker, is specifically related to a kind of universal circuit breaker arc control device.
Background technology
Omnipotent breaker is used for distributing the overload, under voltage, short circuit of electric energy and protection circuit and power-supply device etc., under normal condition, can be used as the usefulness of the not frequent transitions of circuit.Withstand current Icw when the basic mechanical design feature of decision omnipotent breaker performance is specified limit short circuit breaking capacity Icu, specified operation short circuit breaking capacity Ics and specified short circuit.Icu, Ics, Icw ability are high more, and arc extinction is difficult more, the electric arc arc control device that also fly out easily, thereby the fail safe of harm electric power system.Therefore, each enterprise all researches and develops the good zero arcing arc-control device of arc extinction performance, all is very necessary from improving the effectiveness aspect, market that still improves low-voltage electrical apparatus manufacturing enterprise in the horizontal aspect of low voltage electrical apparatus technology in addition.Arc control device are installed in the omnipotent breaker, and its effect mainly is when the dynamic and static contact of disjunction produces electric arc, and it is extinguished rapidly, and realizes zero arcing.Existing arc control device mainly are made up of arc extinguishing grid pieces, arc separating wall and striking grid, and the multi-disc arc extinguishing grid pieces is installed in parallel in together, place the side of moving contact.There is following defective in existing omnipotent breaker arc control device: the striking effect is undesirable, and the electric arc arc control device of overflowing easily can't be realized zero arcing.
Summary of the invention
Influence the deficiency of breaking capacity in order to overcome existing omnipotent breaker arc control device arc quenching effect difference, the utility model provides a kind of universal circuit breaker arc control device, these universal circuit breaker arc control device adopt the arc extinguishing grid pieces of labyrinth structure and install the electric arc plate washer additional, electric arc can promptly be elongated cooling and extinguish, has higher breaking capacity, simultaneously, the electric arc arc control device of also can not overflowing have been realized zero arcing.
The technical solution of the utility model is: these universal circuit breaker arc control device comprise arc extinguishing grid pieces, arc separating wall and striking grid, corresponding 2 dividing plate inwalls are provided with parallel equidistant slot on the arc separating wall, arc extinguishing grid pieces is inserted in the described slot, the striking grid are arranged on a side of arc extinguishing grid pieces and corresponding with fixed contact, an end of corresponding moving contact is provided with the arc leading angle that is " V " type on the arc extinguishing grid pieces, the both sides of arc leading angle are the involute shape, the concavo-convex staggered formation labyrinth structure in the arc leading angle place of adjacent arc extinguishing grid pieces.
The bottom outside of described arc separating wall is provided with insulation electric arc plate washer and metal arc plate washer, and described insulation electric arc plate washer is an insulating material, and the metal arc plate washer is a metal material, is equipped with sieve aperture on insulation electric arc plate washer and the metal arc plate washer.
Described insulation electric arc plate washer and metal arc plate washer are arranged in parallel, and insulation electric arc plate washer is 2 and close arc extinguishing grid pieces, and the metal arc plate washer is 1.
The utlity model has following beneficial effect: owing to take such scheme, when the moment of moving contact and fixed contact disjunction, the concavo-convex staggered arc extinguishing grid pieces of arc leading angle elongates electric arc, electric arc can be cooled off fast extinguish, thereby improved breaking capacity.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
By Fig. 1 in conjunction with Fig. 2, shown in Figure 3, these universal circuit breaker arc control device comprise arc extinguishing grid pieces 1, arc separating wall 2 and striking grid 3, corresponding 2 dividing plate 4 inwalls are provided with parallel equidistant slot 5 on the arc separating wall 2, arc extinguishing grid pieces 1 is inserted in the described slot 5, striking grid 3 are arranged on a side of arc extinguishing grid pieces 1 and corresponding with fixed contact, an end of corresponding moving contact 8 is provided with the arc leading angle that is " V " type on the arc extinguishing grid pieces 1, the both sides of arc leading angle are the involute shape, the concavo-convex staggered formation labyrinth structure in the arc leading angle place of adjacent arc extinguishing grid pieces 1.When making arc extinguishing grid pieces 1, the arc leading angle of " V " type designs at the center of departing from arc extinguishing grid pieces 1 or arc leading angle is the non-centrosymmetry shape, during assembling the 1 upset stack of adjacent arc extinguishing grid pieces is got final product.When the moment of moving contact 8 and fixed contact disjunction, the concavo-convex staggered arc extinguishing grid pieces 1 of arc leading angle elongates electric arc, electric arc can be cooled off apace extinguish, and has higher breaking capacity.
By Fig. 1 in conjunction with Fig. 2, shown in Figure 3, the bottom outside of described arc separating wall 2 is provided with insulation electric arc plate washer 6 and metal arc plate washer 7, described insulation electric arc plate washer 6 is an insulating material, metal arc plate washer 7 is a metal material, be equipped with sieve aperture on insulation electric arc plate washer 6 and the metal arc plate washer 7, sieve aperture makes air-flow unimpeded, has guaranteed that air-flow is unimpeded, reduces arc control device pressure.Insulation electric arc plate washer 6 plays the effect that prevents that electric arc from overflowing outward, makes the electric arc arc separating wall 2 that can not fly out.
In conjunction with Fig. 2, shown in Figure 3, described insulation electric arc plate washer 6 and metal arc plate washer 7 are arranged in parallel by Fig. 1, and insulation electric arc plate washer 6 is 2 and close arc extinguishing grid pieces 1, and metal arc plate washer 7 is 1.
