Description
Technical field
The utility model discloses a kind of electric auxiliaring device, refer more particularly to a kind of chopper electric auxiliaring device.
Background technology
Electric current that chopper refers to close, carry and cut-off under normal loop condition and can close, carrying and the switching device of electric current that cut-offs under abnormal loop condition within the time of regulation. Chopper is divided into primary cut-out and low-voltage circuit breaker by its use scope, and high-low pressure identification of boundaries is fuzzyyer, generally more than 3kV is called High-Voltage Electrical Appliances. Chopper can be used to distribute electric energy; infrequently start asynchronous motor; power circuit and motor etc. are carried out protection, when there is serious overloads or the fault such as short-circuit and under-voltage when them can automatic shutdown circuit, its function is equivalent to Fuse switch and crosses the combination of underheat relay etc. And after disjunction fault current, generally need not change parts. At present, obtain a wide range of applications. In the generation of electricity, conveying, use, distribution is an extremely important link. Distribution system includes transformator and various high and low voltage electrical equipment equipment, and low-voltage circuit breaker is then the electrical equipment that a kind of use has a large capacity and a wide range. Existing chopper does not have the abilities such as heat dropout, electromagnetic trip, it is easy to make electrical equipment damage.
Utility model content
The chopper electric auxiliaring device of the abilities such as the technical problems to be solved in the utility model there is provided one can make chopper have heat dropout, electromagnetic trip.
In order to solve above-mentioned technical problem, this utility model provides a kind of chopper electric auxiliaring device, it is characterised in that: include bimetal leaf, inflaming retarding shell, trip gear and electromagnetic system; Being provided with bimetal leaf in described inflaming retarding shell, bimetal leaf is connected with being connected metallic rod by connecting line, connects metallic rod and connects in chopper; Being provided with electromagnetic system in described chopper, electromagnetic system is connected with trip gear by connecting line, is provided with solenoid in electromagnetic system, and solenoid drives electromagnetic core by magnetic force, and solenoid is suitable with electromagnetic core.
As further improvement of the utility model, described chopper electric auxiliaring device is loaded on the right side of chopper.
As further improvement of the utility model, described chopper electric auxiliaring device is for using in the circuit of rated current 63A.
Adopting said structure, it has the beneficial effects that: the chopper electric auxiliaring device of the abilities such as this utility model provides one can make chopper have heat dropout, electromagnetic trip.
