Abstract
The invention relates to a mutual inductance device for a temperature-control-type low-voltage circuit breaker. The mutual inductance device for the temperature-control-type low-voltage circuit breaker comprises a shell. A box cover is placed on the shell. A wiring through hole is placed on the shell. A component accommodating area is placed inside the shell. The mutual inductance device for the temperature-control-type low-voltage circuit breaker is characterized in that a mutual inductor is placed inside the component accommodating area; a communication cable is placed on the mutual inductor; meanwhile the communication cable penetrates through the wiring through hole; and a communication connector component is placed on the end tip of the communication cable. Furthermore, a temperature control component is placed on the communication cable. Therefore, the communication connector component can be connected with external devices with a plurality of specifications, when the current of the mutual inductor reaches 0.4 In, output power needed by the mutual inductor is well guaranteed, and when the current of the mutual inductor reaches 1.0 In, temperature rising can also be guaranteed. Furthermore, because heat moves outwards through a heat dissipation power resistor, not only service life of the mutual inductor can be prolonged but also measurement accuracy of the mutual inductor can be improved. Meanwhile, material cost of the mutual inductor can be reduced.
