Abstract
The invention belongs to the field of low-voltage apparatuses, and particularly relates to an arc extinguishing chamber. Aiming at the problem that a traditional arc extinguishing chamber is finite in capacity in an arc drawing process, the invention provides an arc extinguishing chamber. The arc extinguishing chamber comprises arc extinguishing grid plates, side plates and gas production plates, wherein the arc extinguishing grid plates are rectangular sheet bodies; a splayed opening and an inverted U-shaped opening on the splayed upper part are formed in the opening part of the lower end of each arc extinguishing grid plate; clamping grooves for clamping the gas production plates are arranged on the side surfaces of the splayed openings; and the sides of the arc extinguishing grid plates are provided with tenon structures matched with slots in the side plates. The side plates are provided with a series of slots for insertion of tenons of the arc extinguishing grid plates; and the gas production plates are the rectangular sheet bodies and can be inserted into the clamping grooves in the arc extinguishing grid plates. Therefore, quick arc drawing and extinguishing can be achieved through a convenient and detachable gas production plate structure.
Description
Technical field
The invention belongs to Low Voltage Electrical Apparatus, be specifically related to a kind of arc-extinguish chamber, particularly a kind of arc-extinguish chamber with replaceable aerogenesis plate.
Technical background
Produce that contain in the medium that the basic reason of electric arc is around device for switching contact itself and contact in a large number can by the electronics dissociated, enough large applied voltage is there is when between the contact of disjunction, and circuital current is when also reaching most your pupil's arc current, will strongly dissociates and form electric arc.Electric arc is the free gas of high temperature high connductivity, and it not only has very large destruction to contact, and makes the time lengthening of open circuit.Therefore, in order to prevent the generation of electric arc, the electric devices such as contactor all arrange arc-extinguish chamber.
Arc-extinguish chamber allows electric arc contact with solid dielectric, reduces arc temperature, thus accelerate the relatively more conventional device of arc extinction.Existing grid arc-extinguish chamber, its arc extinguishing is limited in one's ability.
Summary of the invention
Technical problem to be solved by this invention is: for the problem that existing grid arc-extinguish chamber arc extinction performance is limited, the invention provides a kind of new structure arc-extinguish chamber, can strengthen the arc extinguishing ability of arc-extinguish chamber.
The technical solution used in the present invention:
A kind of arc-extinguish chamber, comprises arc extinguishing grid pieces, side plate and aerogenesis plate; Described arc extinguishing grid pieces is rectangle lamellar body, lower ending opening position is the "eight" shape opening of bottom and the inverted U-shaped opening on "eight" shape top, the side of "eight" shape opening arranges the draw-in groove of card aerogenesis version, arc extinguishing grid pieces side is arranged the tenon structure matched with slot on side plate.Side plate arranges a series of slot for the grafting of arc extinguishing grid pieces tenon; Aerogenesis version is rectangle lamellar body, can insert in the draw-in groove of arc extinguishing grid pieces.
Further, described aerogenesis version arranges air dispelling hole.
Further, described aerogenesis version being arranged air dispelling hole is slit shape, matches with the gap that arc extinguishing grid pieces is formed between any two.
The invention has the beneficial effects as follows: a kind of arc-extinguish chamber of the present invention, by arranging aerogenesis plate, make arc-extinguish chamber when producing electric arc, aerogenesis plate produces gas under arcing, increases internal mask pressure, strengthens arc extinguishing ability.Adopt structure of the present invention, closely, area is large, and aerogenesis is excellent for its aerogenesis plate and contactor distance simultaneously; Aerogenesis plate is detachable simultaneously, can change; Aerogenesis plate can also arrange air dispelling hole, the elongation of electric arc can be conducive to.

Fig. 2 is the front view of described a kind of arc-extinguish chamber;
The arc extinguishing grid pieces schematic diagram of a kind of arc-extinguish chamber described in Fig. 3;
Fig. 4 is the schematic diagram of described side plate;
In figure, 1-arc extinguishing grid pieces, 2-side plate, 3-aerogenesis plate, 11-"eight" shape opening, the inverted U-shaped opening of 12-, 13-draw-in groove, 14-tenon, 21-groove, 31-air dispelling hole.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.
A kind of arc-extinguish chamber as shown in Figure 1, Figure 2, Figure 3, Figure 4, is characterized in that: comprise arc extinguishing grid pieces 1, side plate 2 and aerogenesis plate 3; Described arc extinguishing grid pieces 1 is rectangle lamellar body, lower ending opening position is the "eight" shape opening 11 of bottom and the inverted U-shaped opening 12 on "eight" shape top, the side of "eight" shape opening 11 arranges the draw-in groove 13 of card aerogenesis version 3, arc extinguishing grid pieces 1 side is arranged tenon 14 structure matched with slot 21 on side plate 2.Side plate 2 arranges a series of slot 21 for the grafting of arc extinguishing grid pieces 1 tenon 14; Aerogenesis version 3 is rectangle lamellar body, can insert in the draw-in groove 13 of arc extinguishing grid pieces 1.
Described aerogenesis version 3 arranges air dispelling hole 31.
Described aerogenesis version 3 is arranged air dispelling hole 31 for slit shape, the gap formed between any two with arc extinguishing grid pieces 1 matches.
A kind of arc-extinguish chamber of the present invention, in use, arcing aerogenesis sheet 3 produces gas, electric arc can be made to lower the temperature and promote that electric arc elongates, thus fast arc extinction; Use middle aerogenesis buttress according to Expenditure Levels, can change; Aerogenesis plate is just to electric arc, and projected area is large, can produce certain gas fast.
More than show and describe general principle of the present invention, principal character and advantage of the present invention.The present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in claimed scope of the present invention.Application claims protection range is defined by appending claims and equivalent thereof.
