Description
Technical field
The utility model relates to a kind of arc insulating apparatus, relates 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 to be " U " type structural design, all is designed with the device of arc leading and suppressing in its arc quenching system, need carry out the protection of arc erosion to " U " type part simultaneously.
But; What the arc insulating apparatus that prior art designed often adopted is that two above parts and several kinds of made parts of raw material come to realize respectively arc leading and suppressing function and defencive function in the arc quenching system; Caused number of parts more; The part manufacture process is numerous and diverse, and the part assembly process is various, and the production cost increases.
The utility model content
The purpose of the utility model is exactly the problems referred to above that exist in the prior art in order to solve, and a kind of integral type arc insulating apparatus is provided.
The purpose of the utility model realizes through following technical scheme:
The integral type arc insulating apparatus; Include arc sheet body; Wherein: described arc sheet body below is provided with integral type bending circular arc zone; Said integral type bending circular arc zone constitutes the defencive function zone with the contact-making surface of arc sheet body below, and the lower end in said integral type bending circular arc zone is provided with the contact spacer, and the outer surface in said integral type bending circular arc zone is provided with limit assembly.
Further, above-mentioned 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 constitutes the striking functional area.
Further, above-mentioned integral type arc insulating apparatus, wherein: described limit assembly is a card article.
Again further, above-mentioned integral type arc insulating apparatus, wherein: described arc sheet body upper end is distributed with reinforcement.
The advantage of the utility model technical scheme is mainly reflected in: through the design of integral type, arc sheet body has body formula bending circular arc zone, can realize arc leading and suppressing function and defencive function in the arc quenching system simultaneously thus.And, the utility model simple structure, part manufacturing and assembling process are simple and easy, are easy to promote.
Description of drawings
The purpose of the utility model, advantage and characteristics will illustrate through the non-limitative illustration of following preferred embodiment and explain.These embodiment only are the prominent examples of using the utility model technical scheme, and all technical schemes of taking to be equal to replacement or equivalent transformation and forming all drop within the scope of the utility model requirement protection.

Fig. 2 is the side surface configurations sketch map of integral type arc insulating apparatus;
Fig. 3 is the integral type arc insulating apparatus and the sketch map that combines of pedestal;
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
Integral type arc insulating apparatus shown in Fig. 1～5 includes arc sheet body 1, and its unusual part is: arc sheet body 1 below that the utility model adopts is provided with integral type bending circular arc zone 2.Specifically, can let the integral type bending circular arc zone 2 and the contact-making surface of arc sheet body 1 below constitute the defencive function zone like this.Simultaneously, the utility model is provided with contact spacer 3 at the lower end in integral type bending circular arc zone 2.Corresponding with it is that the outer surface in integral type bending circular arc zone 2 is provided with limit assembly.
With regard to the utility model one preferred implementation, combine closely with quiet busbar 7 in order to promote the pedestal 8 that this device combines with subsequent installation, the limit assembly of employing is a card article 4.Like this, can let 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, let the extension limit 5 and the side of arc sheet body 1 upper end constitute the striking functional area.
Certainly, consider that the bulk strength of the utility model is guaranteed, arc sheet body 1 upper end is distributed with reinforcement 6.
Like Fig. 2～5; Actual operating position in conjunction with the utility model; Quiet busbar 7 is a sheet metal component; Have necessary R angle at quiet busbar 7, be placed in the pedestal 8 in quiet busbar 7 structural design moulding, the R angle of quiet busbar 7 will make and produce a distance L 1 between this part horizontal plane and the vertical plane.Be to place between quiet busbar 7 and the pedestal 8 on this arc sheet body 1 assembly relation.Because the existence at distance L 1 and R angle has 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 location of product in the practical set process solve synchronously.
As shown in Figure 5, based on " integral type " design concept with and operational environment, the utility model should be designed to thermosetting part or resistant to elevated temperatures thermoplastic component.Do not possess at raw material under the prerequisite of arc extinguishing 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 the prior art become 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; When producing electric arc and magnetic fluid etc., rapidly it is introduced in the arc extinguishing grid pieces 9; Reduce the activity of separating out of unfavorable free electric arc and magnetic fluid etc., realized the required rapid arc extinguishing function of the utility model.
Can find out that through above-mentioned character express behind employing the utility model, through the design of integral type, arc sheet body has body formula bending circular arc zone, can realize arc leading and suppressing function and defencive function in the arc quenching system simultaneously thus.And, the utility model simple structure, part manufacturing and assembling process are simple and easy, are easy to promote.
