Description
Technical field
The present invention relates to a kind of arc insulating apparatus, particularly relate to a kind of integral type arc insulating apparatus.
Background technology
In low-voltage circuit breaker major loop, quiet busbar is common is " U " type structural design, is all designed with the device of arc leading and suppressing in its arc quenching system, needs the protection " U " type part being carried out to arc erosion simultaneously.
But; what the arc insulating apparatus designed by prior art often adopted is that two or more part and the part made by several raw material realize arc leading and suppressing function and defencive function in arc quenching system respectively; result in number of spare parts more; part manufacture process is numerous and diverse; Assembly of the parts operation is various, and production cost increases.
Summary of the invention
Object of the present invention is exactly to solve the above-mentioned problems in the prior art, provides a kind of integral type arc insulating apparatus.
Object of the present invention is achieved through the following technical solutions:
A kind of integral type arc insulating apparatus; include arc sheet body; wherein: below described arc sheet body, be provided with integral type bending circular arc sector; the contact-making surface that described integral type bends below circular arc sector and arc sheet body forms defencive function region; the lower end of described integral type bending circular arc sector is provided with contact spacer, and the outer surface of described integral type bending circular arc sector 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 extension limit, and the side of described extension limit and arc sheet body upper end forms 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, and arc sheet body, with body formula bending circular arc sector, can realize arc leading and suppressing function and defencive function in arc quenching system thus simultaneously.Further, simple structure of the present invention, part manufacture and assembling process simple and easy, be easy to promote.
Accompanying drawing explanation
Object of the present invention, advantage and disadvantage, by for illustration and explanation for the non-limitative illustration passing through preferred embodiment below.These embodiments are only the prominent examples of application technical solution of the present invention, allly take equivalent replacement or equivalent transformation and the technical scheme that formed, all drop within 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 close-up schematic view of Fig. 3;
Fig. 5 is that arc leading and suppressing defencive function realizes 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: be provided with integral type bending circular arc sector 2 below the arc sheet body 1 that the present invention adopts.Specifically, integral type can be allowed like this to bend circular arc sector 2 and to form defencive function region with the contact-making surface below arc sheet body 1.Meanwhile, the present invention is provided with contact spacer 3 at the lower end of integral type bending circular arc sector 2.Corresponding with it, the outer surface of integral type bending circular arc sector 2 is provided with limit assembly.
With regard to the present invention one preferably execution mode, the pedestal 8 be combined with subsequent installation to promote this device is combined closely with quiet busbar 7, and the limit assembly of employing is card article 4.Like this, the integral type bending jut of circular arc sector 2 and the sidewall of pedestal 8 can be allowed to 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, extension limit 5 is allowed to form striking functional area with the side of arc sheet body 1 upper end.
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 service condition of the present invention, quiet busbar 7 is sheet metal component, necessary R angle is had at quiet busbar 7, be placed in pedestal 8 quiet busbar 7 structural design is shaping, the R angle of quiet busbar 7 will make to produce a distance L1 between this part horizontal plane and vertical plane.This arc sheet body 1 assembly relation is placed between quiet busbar 7 and pedestal 8.Due to the existence at distance L1 and R angle, achieve the structure of arc sheet body 1 in this cooperation place.Specifically, and as shown in Figure 4, order distance L1> distance L2> distance L3, so solves the location of arc sheet body 1 at theoretical fit on, the part positioning synchronous of product in practical set process is solved.
As shown in Figure 5, based on " integral type " design concept and its operational environment, the present invention should be designed to thermosetting part or resistant to elevated temperatures thermoplastic component.Do not possess the prerequisite of arc-suppression function at raw material under, 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 as L4 ' * L5 ', make it between arc extinguishing grid pieces 9 as minimum is connected space.Thus, certain restriction and regular is carried out to the scope of activities of disordered motion electric arc and magnetic fluid, when generation electric arc and magnetic fluid etc. rapidly by it introducing arc extinguishing grid pieces 9, decrease the precipitation activity of unfavorable free electric arc and magnetic fluid etc., realize rapid arc-suppression function required for the present invention.
Can be found out by above-mentioned character express, after adopting the present invention, by the design of integral type, arc sheet body, with body formula bending circular arc sector, can realize arc leading and suppressing function and defencive function in arc quenching system thus simultaneously.Further, simple structure of the present invention, part manufacture and assembling process simple and easy, be easy to promote.
