Abstract
The invention relates to an integrated arc isolating device which comprises an arc isolating piece body. The integrated arc isolating device is characterized in that an integrated buckling circular-arc area is arranged on the lower portion of the arc isolating piece body, and the integrated buckling circular-arc area and a contact surface below the arc isolating piece body form a protection function area. Meanwhile, a contact positioning piece is arranged at the lower end of the integrated buckling circular-arc area, and a limiting assembly is arranged on the outer surface of the integrated buckling circular-arc area. Thus, by the adoption of the integrated design, the arc isolating piece body is provided with the integrated buckling circular-arc area, and the functions of arc striking and arc extinguishing and the protection function in an arc extinction system can be achieved at the same time. In addition, the integrated arc isolating device is simple in structure, simple and convenient in part manufacturing and assembling process, and easy to popularize.
Description
Technical field
The present invention relates to a kind of arc insulating apparatus, relate in particular to a kind of integral type arc insulating apparatus.
Background technology
In the low-voltage circuit breaker major loop, quiet busbar is common is " U " type structural design, all is designed with the device of arc leading and suppressing in its arc quenching system, needs simultaneously " U " type part is carried out the protection of arc erosion.
But; what the designed arc insulating apparatus of prior art often adopted is that two above parts and the made part of several raw material are realized respectively arc leading and suppressing function and defencive function in arc quenching system; caused number of spare parts more; the part manufacture process is numerous and diverse; the Assembly of the parts operation is various, and the production cost increases.
Summary of the invention
Purpose of the present invention is exactly in order to solve the above-mentioned problems in the prior art, and a kind of integral type arc insulating apparatus is provided.
Purpose of the present invention is achieved through the following technical solutions:
A kind of integral type arc insulating apparatus; include arc sheet body; wherein: be provided with integral type bending circular arc below described arc sheet body regional; contact-making surface formation defencive function zone below described integral type bending circular arc zone and arc sheet body; the lower end in described integral type bending circular arc zone is provided with the contact spacer, and the outer surface in described integral type bending circular arc zone is provided with limit assembly.
Further, above-mentioned a kind of integral type arc insulating apparatus, wherein: described arc sheet body upper end is distributed with the extension limit, and the side of described extension limit and arc sheet body upper end consists of the striking functional area.
Further, above-mentioned a kind of integral type arc insulating apparatus, wherein: described limit assembly is card article.
Again further, above-mentioned a kind of integral type arc insulating apparatus, wherein: described arc sheet body upper end is distributed with reinforcement.
The advantage of technical solution of the present invention is mainly reflected in: by the design of integral type, arc sheet body can be realized arc leading and suppressing function and defencive function in arc quenching system thus simultaneously with body formula bending circular arc zone.And, simple structure of the present invention, part manufacturing and assembling process are simple and easy, are easy to promote.
Description of drawings
Purpose of the present invention, advantage and disadvantage will be for illustration and explanation by the non-limitative illustration of following preferred embodiment.These embodiment are only the prominent examples of using technical solution of the present invention, and all technical schemes of taking to be equal to replacement or equivalent transformation and forming are within all dropping on the scope of protection of present invention.

Fig. 2 is the side surface configurations schematic diagram of this integral type arc insulating apparatus;
Fig. 3 be this integral type arc insulating apparatus and pedestal in conjunction with schematic diagram;
Fig. 4 is the local enlarged diagram of Fig. 3;
Fig. 5 is that the arc leading and suppressing defencive function is realized organigram.
Embodiment
A kind of integral type arc insulating apparatus as shown in Fig. 1～5 includes arc sheet body 1, and its unusual part is: the present invention adopts arc sheet body 1 below is provided with integral type bending circular arc zone 2.Specifically, can allow like this contact-making surface of integral type bending circular arc zone 2 and arc sheet body 1 below consist of the defencive function zone.Simultaneously, 2 lower end is provided with contact spacer 3 in integral type bending circular arc zone in the present invention.Correspondingly with it is that the outer surface in integral type bending circular arc zone 2 is provided with limit assembly.
With regard to the better execution mode of the present invention one, in order to promote pedestal 8 that this device is combined with subsequent installation and quiet busbar 7 in conjunction with closely, the limit assembly of employing is card article 4.Like this, can allow the jut in integral type bending circular arc zone 2 and the sidewall of pedestal 8 carry out certain clearance space.
Further, in order to promote the effect of striking, arc sheet body 1 upper end is distributed with extension limit 5.Thus, allow extension limit 5 and the side of arc sheet body 1 upper end consist of the striking functional area.
Certainly, consider that bulk strength of the present invention is guaranteed, arc sheet body 1 upper end is distributed with reinforcement 6.
As Fig. 2～5, in conjunction with actual operating position of the present invention, quiet busbar 7 is sheet metal component, have necessary R angle at quiet busbar 7, in quiet busbar 7 structural design moulding were placed on pedestal 8, the R angle of quiet busbar 7 will make and produce a distance L 1 between this part horizontal plane and vertical plane.To be placed between quiet busbar 7 and pedestal 8 on this arc sheet body 1 assembly relation.Due to the existence of distance L 1 with the R angle, realized the structure of arc sheet body 1 in this cooperation place.Specifically, and as shown in Figure 4, make distance L 1〉distance L 2〉distance L 3, so in the location that theoretical fit on has solved arc sheet body 1, make the part positioning synchronous of product in the practical set process solve.
As shown in Figure 5, based on " integral type " design concept with and operational environment, the present invention should be designed to thermosetting part or resistant to elevated temperatures thermoplastic component.Do not possess at raw material under the prerequisite of arc-suppression function, integrate its structure, make it to have more powerful striking function.Make the zone of action of L4*L5 electric arc and magnetic fluid etc. under prior art become the L5 ' for L4 ' *, make it with arc extinguishing grid pieces 9 between be the minimum space that is connected.Thus, scope of activities to disordered motion electric arc and magnetic fluid is carried out certain restriction and regular, rapidly it is introduced in arc extinguishing grid pieces 9 when producing electric arc and magnetic fluid etc., reduced the activity of separating out of unfavorable free electric arc and magnetic fluid etc., realize rapid arc-suppression function required for the present invention.
Can find out by above-mentioned character express, after adopting the present invention, by the design of integral type, arc sheet body can be realized arc leading and suppressing function and defencive function in arc quenching system thus simultaneously with body formula bending circular arc zone.And, simple structure of the present invention, part manufacturing and assembling process are simple and easy, are easy to promote.
