Description

Trans Assembly

The present invention relates to a transformer assembly, and more particularly, to a transformer assembly in which a diode block enables electrical connection without wiring.

In general, a transformer (or transformer) is a device that converts the magnitude of an alternating voltage using an electromagnetic induction phenomenon. In this case, an induced electromotive force is generated due to the electromagnetic induction phenomenon, and an induced current flows so that an alternating current can be induced.

In addition, a plurality of diodes are connected as a rectifier to a conventional transformer using AC power.

However, the connection of a plurality of diode blocks to a conventional transformer is made through wiring, and the wiring connection is complicated. There was a problem to reduce the efficiency of the.

In addition, the conventional transformer generates a lot of heat. A separate water-cooled passage through which cooling water continuously flows is formed inside the transformer to dissipate the heat. However, if the water-cooled passage is formed as described above, the volume of the transformer increases. There is a problem in that the insulation resistance of the transformer is reduced by the cooling water continuously flowing along the water-cooling passage when a water-cooling passage through which the cooling water flows continuously is formed in the transformer.
