Document Type and Number:
Japanese Patent JP2016102626
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a transformer cooling apparatus, a transformer cooling system and a transformer cooling method for underground substation not using water but saving space as much as possible.SOLUTION: A first transformer cooling apparatus 10A is a device installed on a position spaced apart from primary cooling means for removing generated heat at a transformer and on a passage where circulating water is circulated so as to cool hot water acting as circulation water after passing through the primary cooling means. The cooling apparatus comprises: a dry-type cooler 11 not using any water for cooling at the time of high temperature and high load by supplying taken surrounding air 1 as cold heat to a heat transfer part 111 heat exchanging with the circulation water supplied into the device; an open-type cooling tower 12 for supplying cold heat by using water for cooling at the time of high temperature and high load and supplying it to a heat exchanger 13 for heat exchanging with the circulation water after passing through the dry-type cooler 11 for cooling the circulation water; and a blower 121 for generating air stream for blowing the surrounding air 1 in sequence to the dry-type cooler 11 and the open-type cooling tower 12.SELECTED DRAWING: Figure 1
