Abstract

The invention provides a small low-voltage on-load automatic voltage regulation single-phase power distribution device, and relates to the field of power distribution devices. The small low-voltage on-load automatic voltage regulation single-phase power distribution device comprises a shell, a transformer body is fixedly connected to the middle in the shell, pore plates are fixedly connected to the left side and the right side of the transformer body, the upper ends and the lower ends of the pore plates are slidably connected into fixing grooves, and the fixing grooves are formed in the middles of the ends, close to the pore plates, of fixing blocks. Vent holes which are uniformly distributed are formed in the pore plates in a penetrating manner. The motor can drive the driving gear to rotate, and the driven gear and the driving gear can drive the rotating shaft to rotate, so that when the motor works, the rotating shaft can drive the cooling fan to rotate synchronously, and wind generated by the cooling fan can penetrate through the pore plate to blow the internal structure of the shell; therefore, heat in the shell can be taken away, and heat dissipation of the internal structure of the shell can be achieved.

Description

technical field [0001] The invention relates to the technical field of power distribution devices, in particular to a small low-voltage on-load automatic voltage regulation single-phase power distribution device. Background technique [0002] The transformer is a device that uses the principle of electromagnetic induction to change the AC voltage.
