Dustproof box type high-cold high-voltage transformer

The invention discloses a dustproof box-type high-cold high-voltage transformer, and relates to the technical field of box-type transformers. The box-type transformer solves the problem that an existing box-type transformer cannot normally operate in an alpine region. The device comprises a box body, the box body is of a structure with an opening in one side, a box door is hinged to the opening of the box body, ventilation openings are oppositely formed in the side wall perpendicular to the box door, and dustproof mechanisms are installed on the ventilation openings; a transformer, a heater and a temperature detector are installed in the box body, the temperature detector is used for detecting a temperature signal in the box body and sending the detection signal to a single-chip microcomputer controller, and the single-chip microcomputer controller is arranged in the box body and controls the heater to conduct heating or not according to the received temperature signal. The method is suitable for alpine regio
