Heat exchange type cooling apparatus for a transformer |
摘要 |
Disclosed herein is a heat exchange type cooling apparatus for a transformer, including: an insulating oil circulation pipe configured in a closed circuit form so that an insulating oil filled in the transformer is discharged to the outside and then returns again to the transformer; an insulating oil pump configured to transfer the insulating oil; and an insulating oil cooling system configured to cool the insulating oil, wherein the insulating oil cooling system includes: a liquid refrigerant maintained in a liquid state during the entire circulation cycle; a refrigerant circulation pipe configured to circulate the liquid refrigerant; a refrigerant pump configured to transfer the liquid refrigerant; and a heat exchanging part configured to heat-exchange the liquid refrigerant and the insulating oil with each other to cool the insulating oil. |

1. A heat exchange type cooling apparatus for a transformer, comprising:
an insulating oil circulation pipe configured in a closed circuit form so that an insulating oil filled in the transformer is discharged to the outside and then returns again to the transformer; an insulating oil pump configured to transfer the insulating oil; and an insulating oil cooling system configured to cool the insulating oil, wherein the insulating oil cooling system includes: a liquid refrigerant maintained in a liquid state during the entire circulation cycle; a refrigerant circulation pipe configured to circulate the liquid refrigerant; a refrigerant pump configured to transfer the liquid refrigerant; and a heat exchanging part configured to heat-exchange the liquid refrigerant and the insulating oil with each other to cool the insulating oil, the heat exchanging part including: a multi-layer channel part including a plurality of layers formed so that the insulating oil flows onto the plurality of layers; an inlet part disposed at an upper portion of the multi-layer channel part; an outlet part disposed at a lower portion of the multi-layer channel part; and a refrigerant casing part configured to enclose the multi-layer channel part and configured so that the liquid refrigerant flows around multi-layer channel part. |
