The utility model relates to a temperature automatic regulating apparatus with molded case circuit breaker overload release characteristics. According to the technical scheme of the utility model, the temperature automatic regulating apparatus with molded case circuit breaker overload release characteristics is characterized by comprising a temperature control element, an adjusting rod and a draw bar. The adjusting rod is arranged on the draw bar in a sliding manner. The contact position of the adjusting rod and the bimetallic strip of a circuit breaker is provided with an inclined plane or a curved plane. The adjusting rod is driven to slide on the draw bar when the temperature control element is bent or telescoped as temperature changes. By adopting the above scheme, the utility model provides the novel temperature automatic regulating apparatus with molded case circuit breaker overload release characteristics, which can be slightly adjusted according to the temperature change.

Description

A kind of automatic temperature control device of breaker of plastic casing overlond trip characteristic
Technical field
The utility model relates to the automatic temperature control 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, makes circuit breaker tripping, thereby realizes the overload protection to circuit and equipment; Therefore, the gap between bimetal leaf and draw bar has determined the overlond trip characteristic in mold cased circuit breaker.But overload characteristic when traditional mold cased circuit breaker dispatches 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 be in the action protection time that surpasses 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 drive adjusting rod slippage on draw bar by temperature control compensating element, again, change the impulse stroke of bimetal leaf, thereby realize the temperature automatic temperature control device of the novel breaker of plastic casing overlond trip characteristic of adjusting automatically.
Realize above-mentioned purpose, the utility model adopts following technical scheme: a kind of automatic temperature control device of breaker of plastic casing overlond trip characteristic, it is characterized in that: include temperature control element, adjusting rod and draw bar, adjusting rod slippage is arranged on draw bar, the contact position corresponding position of the bimetal leaf of adjusting rod and circuit breaker is provided with inclined-plane or curved surface, described temperature control element one end is directly or indirectly arranged on Shell of circuit breaker, the other end is arranged on adjusting rod, temperature control element varies with temperature and bending occurs or can drive the slippage of adjusting rod on draw bar when flexible, the slippage of adjusting rod realizes the inclined-plane of adjusting rod or curved surface with respect to the change of the contact position of bimetal leaf.
By adopting such scheme, can to Thermomagnetic type breaker of plastic casing overlond trip characteristic, carry out temperature self-regulating joint and compensation according to actual environment temperature, to guarantee that Thermomagnetic type breaker of plastic casing is in the wide temperature scope of application, can avoid pyromagnetic fixed breaker due to the distortion of temperature-sensing element, and cause the skew of overload characteristic, also can not adopt and traditional under hot environment, fall appearance simultaneously.
Further setting of the present utility model is: described draw bar is provided with chute near a side of the bimetal leaf of circuit breaker, and described adjusting rod is placed on chute, on the side of described chute, is provided with recess, and inclined-plane or the curved surface of described adjusting rod appear from recess; The link position of described temperature control element and adjusting rod is positioned at the upper side of adjusting rod, and the upper side of described adjusting rod is fixed with two spacers, and temperature control element one end is placed in and between two spacers, forms being connected of temperature control element one end and adjusting rod; Described temperature control element is hinged is arranged on the upper side of adjusting rod or the link position of described temperature control element and adjusting rod is positioned on the end face of adjusting rod, and described temperature control element becomes straight plate shape or V-arrangement.
By adopting such scheme, be further optimize product structure, the convenience of performance and use, wherein to adopt above-mentioned several modes to arrange more reasonable for temperature control element.
Below in conjunction with accompanying drawing, the utility model is further described.
