COLLING SYSTEM FOR DISTRIBUTING BOARD USING GEOTHERMAL

摘要

The present invention discloses a switchgear cooling system capable of cooling heat generated in a voltage transformer and a current transformer of switchgear in a natural circulation manner by using geothermal heat. The switchgear cooling system according to the present invention comprises: a geothermal cooling and heating device which generates air cooled by heat exchange between the geothermal heat and a refrigerant; a flow pipe unit which is embedded in a flow pipe under the ground, and further cools primarily cooled air flowing from the geothermal cooling and heating device, through an underground temperature; and a blower fan unit which takes in a secondarily cooled air cooled in the flow pipe unit when the temperature in the switchgear is raised in accordance with heat generated in the voltage transformer and the current transformer for measurement, and then discharges the air into the switchgear to cool the high temperature. According to the present invention, the temperature in the switchgear is lowered to suppress overheating caused by a power supply device, and it is possible to prevent a fire by blocking the inflow of foreign substances.
