Abstract
The utility model provides an arc extinguishing chamber of a vacuum alternating current contactor. The arc extinguishing chamber of the vacuum alternating current contactor comprises an arc extinguishing chamber body. The arc extinguishing chamber body is an overall cavity member. The arc extinguishing chamber body is internally provided with a plurality of baffle plates to divide the cavity of the arc extinguishing chamber body into a plurality of spaces. Since the arc extinguishing chamber body is the overall cavity member, the arc extinguishing body is internally provided with the plurality of baffle plates to divide the cavity of the arc extinguishing chamber body into the plurality of spaces, and a contact terminal can be covered to form a vacuum state, so that the vacuum can be utilized to carry out arc extinguishing on the alternating current contactor, the arc extinguishing effect is greatly improved, the drop-out current of the alternating current contactor reaches multiple times of that of the current ordinary switch, a metal arc chute is not used, and a large amount of nonferrous metal is saved for the country.
Description
Technical field
The utility model relates to a kind of arc-extinguish chamber, and particularly a kind of arc-extinguish chamber of contactor belongs to the technical field of A.C. contactor.
Background technology
Traditional arc-extinguish chamber is comprised of metal arc-chute and insulating trip, owing to be subjected to the restriction of inner space, the quantity of sheet metal not to allow to increase, therefore, has affected the arc quenching effect of arc-extinguish chamber; And wasted national a large amount of non-ferrous metal.
The utility model content
It is good that technical problem to be solved in the utility model provides a kind of arc quenching effect, and the arc-extinguish chamber of vacuum A. C. contactor simple in structure.
In order to solve the problems of the technologies described above, the arc-extinguish chamber of a kind of vacuum A. C. contactor of the utility model, comprise the arc-extinguish chamber body, described arc-extinguish chamber body is whole Cavity structural member, is provided with a plurality of dividing plates in the described arc-extinguish chamber body cavity of arc-extinguish chamber body is divided into a plurality of spaces.
The arc-extinguish chamber of above-mentioned vacuum A. C. contactor, wherein, each both sides, described space is respectively equipped with partition.
The beneficial effects of the utility model:
Because described arc-extinguish chamber body is whole Cavity structural member, be provided with a plurality of dividing plates in the described arc-extinguish chamber body cavity of arc-extinguish chamber body is divided into a plurality of spaces, contact can be covered and forms vacuum state, thereby, utilize vacuum that converter is carried out arc extinguishing, greatly improved arc quenching effect, the drop-out current of converter is reached more than the present regular tap several times, and without the metal arc-chute, for country has saved a large amount of non-ferrous metals.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
In order to solve the problems of the technologies described above, the arc-extinguish chamber of a kind of vacuum A. C. contactor of the utility model, comprise arc-extinguish chamber body 1, described arc-extinguish chamber body 1 is whole Cavity structural member, is provided with a plurality of dividing plates 2 in the described arc-extinguish chamber body 1 cavity of arc-extinguish chamber body is divided into a plurality of spaces 3; Each 3 both sides, described space is respectively equipped with partition 4, because described arc-extinguish chamber body is whole Cavity structural member, be provided with a plurality of dividing plates in the described arc-extinguish chamber body cavity of arc-extinguish chamber body is divided into a plurality of spaces, contact can be covered and forms vacuum state, thereby, utilize vacuum that converter is carried out arc extinguishing, greatly improved arc quenching effect, the drop-out current of converter is reached more than the present regular tap several times, and without the metal arc-chute, for country has saved a large amount of non-ferrous metals.
The description of above embodiment is comparatively concrete, detailed; but can not therefore be interpreted as the restriction to this patent scope; should be noted that; for the person of ordinary skill of the art; without departing from the concept of the premise utility; can also make some distortion and improvement, these all belong to protection range of the present utility model.
