The invention discloses a transformer with functions of shock absorption, water resistance and heat dissipation. Connection, internal thread sleeve, connecting rod, slider, side plate, glass cooling pipe, second motor, fan blade and mounting plate, the present invention is provided with a shock absorption device, which can avoid the problem of damage to internal components caused by long-term operation of the transformer , To better protect the transformer, it is equipped with a first motor, a first pulley, a second pulley, a two-way screw, an internal thread sleeve and a connecting rod, so as to adjust the height of the transformer box and the ground to avoid rainwater entering the transformer box and The ground rain erodes or submerges the bottom of the transformer box, and a second motor and fan blades are provided to uniformly dissipate the electrical components in the transformer box, speed up the air circulation rate, and improve the heat dissipation effect.
