Abstract
The utility model relates to a breaker thermal trip system with a novel conducting sheet. The system comprises a bimetallic strip. A connecting terminal and an arc guide plate are arranged at two sides of the bimetallic strip respectively. The end part of the arc guide plate is connected with the bimetallic strip. A conducting sheet is arranged between the connecting terminal and the bimetallic strip. One end of the conducting sheet is connected with the connecting terminal, and the other end is connected with the bimetallic strip. Two ends of the conducting sheet are straight line ends. An anti-buffer part formed through continuous bending is arranged between the two straight line ends. The breaker thermal trip system is simple in structure and easy to install. The conducting sheet is connected between the connecting terminal and the bimetallic strip, thus during the wire connection of the connecting terminal, the W-shaped anti-buffer part is arranged to bear buffer effects brought by twisting force and external force, that displacement of the bimetallic strip is generated to further affect characteristics because of force application is avoided, and therefore the calibration qualified rate of a breaker is raised. When a breaker is subjected to a short circuit impact, the influence caused by electrodynamic force is reduced.
Description
Technical field
The utility model relates to circuit breaker, relates in particular to a kind of breaker thermal tripping system with novel conductive sheet.
Background technology
Circuit breaker refers to the electric current that can close, carry and cut-off under normal loop condition, and can close, in official hour, carry and cut-off the switching device of the electric current under abnormal loop condition (comprising short circuit condition).Circuit breaker can be used to distribute electric energy; do not start continually asynchronous motor; power circuit and motor etc. are carried out to protection, can automatic shutdown circuit in the time that serious overload or short circuit and the fault such as under-voltage occur for they, its function is equivalent to Fuse switch and the combination of crossing underheat relay etc.And after disjunction fault current, generally do not need to change parts.At present, the conducting strip of its hot tripping system inside of traditional circuit breaker all adopts hard connection or U-shaped to connect, this structure makes troubles not only to the assembling of circuit breaker, simultaneously in the time of binding post wiring, easily bimetal leaf is caused to displacement, affect thus its characteristic, and affect the calibration qualification rate of circuit breaker.
Utility model content
The applicant, for above-mentioned existing issue, provides a kind of breaker thermal tripping system with novel conductive sheet, has advantages of that assembling is easy, and has improved the calibration qualification rate of circuit breaker.
The technical scheme that the utility model adopts is as follows:
A kind of breaker thermal tripping system with novel conductive sheet, comprise bimetal leaf, the both sides that are positioned at described bimetal leaf arrange respectively binding post and lead arc plate, described end of leading arc plate is connected with described bimetal leaf, conducting strip is arranged between described binding post and bimetal leaf, one end of described conducting strip is connected with binding post, and the other end connects bimetal leaf; The two ends of described conducting strip are rectilinear end, are provided with the anti-slow portion that continuous bend is shaped between two rectilinear ends.
Its further technical scheme is:
Anti-slow portion is " W " shape.
The beneficial effects of the utility model are as follows:
The utility model is simple in structure, simple installation, by be connected conducting strip between binding post and bimetal leaf, make it in the time of binding post wiring, by being set, the anti-slow portion of " W " shape bears the cushioning effect that torsion and external force are brought, thereby avoid the stressed generation displacement of bimetal leaf influencing characterisitic, thereby improve the calibration qualification rate of circuit breaker, in the time that circuit breaker suffers short-circuit impact, reduced the impact that electric power causes.
Accompanying drawing explanation
Fig. 1 is with the structural representation of circuit breaker of the present utility model.
Fig. 2 is the utility model structural representation.
Wherein: 1, handle; 2, operating mechanism; 3, hot tripping system; 4, electromagnetic system; 5, arc control device; 6, conducting strip; 301, binding post; 302, bimetal leaf; 303, lead arc plate; 601, line part; 602, anti-buffer part.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As shown in Figure 1, circuit breaker is made up of handle 1, operating mechanism 2, hot tripping system 3, electromagnetic system 4, arc control device 5, a kind of breaker thermal tripping system with novel conductive sheet, as shown in Figure 2, comprise bimetal leaf 302, the both sides that are positioned at bimetal leaf 302 arrange respectively binding post 301 and lead arc plate 303, the end of leading arc plate 303 is connected with bimetal leaf 302, conducting strip 6 is arranged between described binding post 301 and bimetal leaf 302, one end of conducting strip 6 and binding post 30) be connected, the other end connects bimetal leaf 302; The two ends of conducting strip 6 are rectilinear end 601, are provided with the anti-slow portion 602 that continuous bend is shaped between two rectilinear ends 601, and anti-slow portion 602 is " W " shape.
As shown in Figure 2, in the time of binding post 301 wiring, by being set, the anti-slow portion 602 of " W " shape bears the cushioning effect that torsion and external force are brought, thereby avoid the stressed generation displacement of bimetal leaf 302 influencing characterisitic, thereby improve the calibration qualification rate of circuit breaker, in the time that circuit breaker suffers short-circuit impact, reduce the impact that electric power causes.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range, referring to claim, within protection range of the present utility model, can be done any type of modification.
