Abstract
Provided is an arc extinguish chamber of a miniature switching device. The arc extinguish chamber comprises a flash barrier and deion plates. The deion plates are riveted on the flash barrier. The flash barrier comprises an upper side panel, a back side panel, and a lower side panel connected in an integrated manner in sequence. The upper side panel and the lower side panel are provided with a plurality of riveting holes corresponding to the deion plates. The back side panel is provided with an upper square opening and a lower square opening, thereby forming a shape of a Chinese character yue. Since the flash barrier has an integrated structure, the flash barrier is suitable to be used in automation assembly, thereby improving product assembly efficiency, and the back side panel has a structure in a shape of a Chinese character ri, so that original a plurality of segments of arcs can be cut again, beneficial for preventing short circuit caused by the arcs gathering at a gas outlet of the arc extinguish chamber. Appropriate pressure and air-blowing effect can be still kept in the arc extinguish chamber, so the arcs pass the deion plates smoothly and are cooled. Original arcs are divided to twice short arcs by a transverse bar on a middle part of the back side panel, thereby improving breaking effect.
Description
Technical field
The utility model relates to a kind of switchette electrical equipment, particularly a kind of arc control device of switchette electrical equipment.
Background technology
Common miniature circuit breaker product as the arc control device of DZ47 series and innovative product thereof by forming behind two identical parts of up/down flash barrier and the grid sheet riveted, when assembling, add in addition with the arc baffle plate of small gap and form complete arc quenching system, this baffle plate is can separate independently with arc control device, when short circuit breaking, because impacted by arc energy larger free gap is arranged, can reduce to a certain extent the generation of arc short circuit and thermal current bounce-back, but should the design because of about two flash barriers, can not automatic riveting production, can only knock by hand the assembling riveted with frock, efficient is low and progressively be tending towards superseded, and less producer adopts.Nowadays on the market more employing be up and down flash barrier and baffle plate merge make into all-in-one-piece; thereby this design solved can not automatic riveting problem greatly improved production efficiency; but because original baffle plate has become fixed; and the small gap on the baffle plate is less; electric arc usually accumulates in this baffle plate inboard when short circuit breaking; cause short circuit and scaling loss grid sheet; the arc control device internal pressure discharges not go out and causes whole arc control device to fall apart; whole arc control device arc quenching effect is reduced greatly, thereby cause product I cu or Ics short circuit breaking capacity defective.
The utility model content
Be the deficiency of the arc control device that solve above-mentioned device for switching, the utility model provides a kind of arc extinction performance good, applicable to the arc quenching chamber structure of the switchette electrical equipment of automatic assembling.
The technical solution adopted in the utility model is:
A kind of arc control device of switchette electrical equipment, comprise flash barrier and grid sheet, grid sheet riveted is on flash barrier, described flash barrier is comprised of the epipleural, back side panel and the lower side panel that link to each other successively of integral type, be equipped with a plurality of riveted holes corresponding with the grid sheet on the described upper and lower side plate, described back side panel is provided with the upper and lower interruption-forming and " says " the font back side panel.
Further, the width of the square opening on the described back side panel equals the distance between the outermost two grid sheets.
Because flash barrier is integral structure, therefore applicable to automatic assembling, thereby can improve assembling product efficient, and back side panel adopts a day character form structure, then some sections original electric arcs can be cut again, so not only being conducive to reduce electric arc is gathered in the arc control device gas outlet and causes short circuit, and still can make and keep suitable pressure and an air-blowing effect in the arc control device, make that electric arc is smooth and easy to be cooled off by the grid sheet, and former electric arc can be divided into 2 times short arc by the horizontal bar at back side panel middle part, in the situation that the limited grid sheet of arc control device volume can not increase and the gas outlet keeps the former labyrinth type design should design energy Effective Raise disjunction effect.
Description of drawings
Fig. 1 is the stereogram of the utility model embodiment.
Fig. 2 is the rearview of the utility model embodiment.
Embodiment
The invention will be further described below in conjunction with drawings and Examples:
Shown in Fig. 1,2, the arc control device of a kind of switchette electrical equipment of the utility model, comprise flash barrier 1 and grid sheet 2, grid sheet 2 riveteds are on flash barrier 1, described flash barrier 1 is comprised of the epipleural 11, back side panel 12 and the lower side panel 13 that link to each other successively of integral type, be equipped with a plurality of riveted holes corresponding with grid sheet 2 on the described upper and lower side plate 11,13, described back side panel is provided with upper and lower square opening 121,122 and forms " saying " font back side panels.Because flash barrier 1 is integral structure, therefore applicable to automatic assembling, thereby can improve assembling product efficient, and back side panel adopts a day character form structure, then some sections original electric arcs can be cut again, so not only being conducive to reduce electric arc is gathered in the arc control device gas outlet and causes short circuit, make that electric arc is smooth and easy to be cooled off by grid sheet 2, and former electric arc can be divided into 2 times short arc by the horizontal bar 123 at back side panel 12 middle parts, in the situation that the limited grid sheet of arc control device volume can not increase this design can Effective Raise disjunction effect.
Among the figure, the width w of the square opening on the best described back side panel 12 equals the distance between the outermost two grid sheets 1.Electric arc when so more being conducive to the circuit breaker short circuit disjunction passes through, and eliminates the generation of Arc Back Strike Phenomena.
Claims (2)
1. the arc control device of a switchette electrical equipment, comprise flash barrier (1) and grid sheet (2), grid sheet (2) riveted is on flash barrier (1), it is characterized in that: described flash barrier (1) is comprised of the epipleural (11), back side panel (12) and the lower side panel (13) that link to each other successively of integral type, be equipped with a plurality of riveted holes corresponding with grid sheet (2) on the described upper and lower side plate (11,13), described back side panel (12) is provided with upper and lower square opening (121,122) and forms " saying " font back side panel.
