Alternating-current low-voltage power distribution cabinet

Abstract

The invention provides an alternating-current low-voltage power distribution cabinet which comprises a power supply box and a power distribution box. The lower surface of the power distribution box is fixedly connected with the left end of the upper surface of a heat conduction plate, a temperature sensor is arranged in the middle of the upper surface of the heat conduction plate, and a fire extinguishing box is arranged at the right end of the upper surface of the heat conduction plate. A direct-current storage battery is arranged on the upper portion of the left side face in the power supply box, a positive electrode end and a negative electrode end are arranged on the right side face of the direct-current storage battery, and a first fixed resistor and a second fixed resistor are connected between the right side face of the positive electrode end and the right side face of the negative electrode end in series. A third fixed resistor is connected in series between the lower side surface of the first fixed resistor and the lower side surface of the large induction coil through a wire; and the upper side surface of the large induction coil is electrically connected with the upper side surface of the second electricity leading sheet through a wire. According to the technical scheme, the technical problems that in the prior art, the direct current-to-alternating current conversion capacity is not achieved, and automatic power-on, automatic fire extinguishing and the like cannot be achieved are effectively solved, and application and popularization are facilitated.
