Abstract
A high-frequency transformer comprises a high-voltage winding and a rectifier bridge, wherein line terminals of the high-voltage winding are respectively connected with a connection bridge arm of the rectifier bridge in the shortest distance; the rectifier bridge is provided with a side shaft parallel to the high-voltage winding axially; the arm of the rectifier bridge bifurcates outside at a certain angle; as the high-voltage winding is wound in barrel shape and two outgoing line ends thereof are respectively at two ends of the barrel shape, the routing distance is shortened, thus reducing the heat emission of the high-voltage winding in work and the chance that a lead punctures an insulating layer; and the bifurcating structure leads to good ventilation effect of the transformer, the rectifier bridge can share one air channel for heat dissipation with an axial through hole of the high-voltage winding and the arrangement that the transformer is installed in a power box is more convenient and reasonable. Besides, a rectifying diode is distributed on the bridge arm and increases the contact area with the outside air, thus leading to good heat dissipation effect and achieving omnibearing heat dissipation. And when the transformer is installed in the power box, the transformer does not need to be attached to the wall of the power box for heat dissipation, thus avoiding the phenomenon of compared high-voltage breakdown and leading to safer work of equipment.
