ABSTRACT:
An object of this invention is to provide a system for utilizing exhaust heat of a stationary induction apparatus in which highly-useful hot water, for example, of about 70.degree. C. can be provided without increasing an operating temperature of the stationary induction apparatus (e.g. a transformer) to such an extent as to adversely affect the lifetime of the stationary induction apparatus. The system of the present invention includes a heat pump 17 which uses, as a high-temperature heat source, a first stationary induction apparatus cooling system which includes a first water-cooled stationary induction apparatus 1, and a first cooling water circulation system 7, and exhaust heat utilization means 8. This heat pump also uses, as a low-temperature heat source, a second stationary induction apparatus cooling system which includes a second stationary induction apparatus 10, and a second cooling water circulation system 16. There is further provided a refrigerator 26 which uses the second stationary induction apparatus cooling system as a high-temperature heat source, and also uses warm water 22 in a cable-cooling cold/warm water tank 21 as a low-temperature heat source.
