Description
Technical field
The utility model relates to the temperature self-compensation adjusting device of the overlond trip characteristic in breaker of plastic casing.
Background technology
In mold cased circuit breaker, when the electric current passing through in circuit breaker is greater than rated current, bimetal leaf heated bending, and amount of bow is greater than the gap between bimetal leaf and draw bar, draw bar is promoted by bimetal leaf, rotate and make circuit breaker tripping forward, thereby realize the overload protection to circuit and equipment; Therefore, the gap between bimetal leaf and draw bar has determined overlond trip characteristic and the load current value in mold cased circuit breaker.But the draw bar of traditional mold cased circuit breaker is integral type, regulate and must change by attachment device the impulse stroke of bimetallic element, the general translation mode that adopts, as shown in Figure 1, in addition, overload characteristic while dispatching from the factory is for example 20 ℃ of adjustment under fiducial temperature, and the ambient temperature of circuit breaker real work is generally at-5 ~ 40 ℃.When surpassing or during lower than fiducial temperature; because bimetal leaf is influenced by ambient temperature; can produce distortion, cause the larger error of circuit breaker overlond trip characteristic, even lose efficacy; make circuit breaker cannot realize effective overload protection; therefore,, when higher than fiducial temperature, need to fall to hold and use; and when lower than fiducial temperature, may surpass the action protection time of regulation.
Summary of the invention
The utility model overcomes the deficiency that prior art exists, a kind of tripping that can either pin in breaker mechanism is provided, can rotate by draw bar active page again, control the subtended angle of draw bar, change the impulse stroke of thrermostatic bimetal-plate, thereby realization regulates, the overload that meets different current specification regulates or temperature adjusting, the temperature self-compensation adjusting device of the main novel hinge-type breaker of plastic casing overlond trip characteristic that can also finely tune according to the variation of temperature self generation.
Realize above-mentioned purpose, the utility model adopts following technical scheme: a kind of temperature self-compensation adjusting device of hinge-type breaker of plastic casing overlond trip characteristic, it is characterized in that: include temperature control element and hinge-type draw bar, wherein hinge-type draw bar includes draw bar active page and draw bar fixed page, draw bar active page and the hinged setting of draw bar fixed page, described draw bar fixed page is connected with the snap close in circuit breaker, the whole one-tenth of described temperature control element " V " type, one side is fixed on draw bar active page, another side is fixedly installed in draw bar fixed page, its kink is corresponding with the articulated position of draw bar active page and draw bar fixed page, temperature control element varies with temperature when bending or upholding and can drive draw bar active page to rotate, change the subtended angle between draw bar active page and draw bar fixed page.
By adopting the scheme of the new construction of hinge-type, can either pin the tripping in breaker mechanism, can rotate by draw bar active page again, control the subtended angle of draw bar, change the impulse stroke of thrermostatic bimetal-plate, thereby realize the fine setting that draw bar active page and draw bar fixed page angle occur according to the variation of temperature self, very convenient.
Further setting of the present utility model is: described draw bar active page includes active page body and hinged circle, active page body and hinged circle are fixedly installed, described draw bar fixed page includes fixed page body and clamping ring, fixed page body and clamping ring are fixedly installed, the hinged circle of described draw bar active page and the clamping ring of draw bar fixed page are coaxially arranged, in the through hole of its formation, be provided with jointed shaft, described temperature control element is arranged on the side of hinge-type draw bar, certainly we also can adopt temperature control element is installed in another way, temperature control element is arranged on to side or the surface of hinge-type draw bar.
By adopting such scheme, be further optimize product structure, the convenience of performance and use, wherein to adopt above-mentioned two kinds of modes to arrange more reasonable for temperature control element, temperature control element also can be arranged between draw bar active page and draw bar fixed page certainly.
Below in conjunction with accompanying drawing, the utility model is further described.
