Description

Heating System using Waste Heat}

The present invention relates to a heating system using waste heat, and more particularly, to a heating system using waste heat capable of improving the heating efficiency of a building by supplying waste heat generated from a transformer.

In general, a transformer includes an input terminal to which a high voltage is applied and an output terminal that converts the input high voltage and outputs a low voltage. The transformer has a cooling means for cooling by dissipating heat generated during the transformation process and high heat generated at ambient temperature. Such a cooling means includes a radiator for dissipating heat and a blower for cooling the radiator. In the cooling process of the transformer, the insulating oil charged in the transformer absorbs the heat generated during the transformation process, and the insulating oil whose temperature has risen by absorbing this heat reaches the radiator through the conduit and is radiated from the radiator by the blower and the insulating oil cooled in the radiator. Flows into the transformer through a conduit and cools the transformer.

In addition, in the case of a dry transformer, there is no cooling means such as a radiator, so waste heat of about 100°C to 120°C generated during the transformation process is generated by the dry transformer itself.
