The invention discloses a
transformer with good dustproof and heat dissipation effects, and the
transformer comprises a supporting mechanism, a
protection mechanism, a heat dissipation mechanism, a controller and a temperature sensor; the supporting mechanism comprises a base, universal self-locking wheels, a
drying box, a
drying agent, through holes and limiting grooves, the limiting grooves aresymmetrically formed in the upper portion of the base, the
drying agent is arranged in the drying box, and the drying agent is arranged in the limiting grooves; the
protection mechanism is arranged above the supporting mechanism, and a sound insulation plate is connected to the inner side wall of the dustproof shell. According to the
transformer with the good dustproof and heat dissipation effects, the temperature sensor is arranged, when the temperature sensor detects that the temperature in the dustproof shell exceeds a set value, the temperature sensor can transmit detected information to the controller, and the controller starts the draught fan and the refrigerating device to
discharge cold air into the dustproof shell through the air exhaust head; therefore, the transformer body in the dustproof shell can be quickly cooled, and the transformer body can be effectively prevented from being damaged due to over-high temperature of the transformer body.
