As mentioned above, in the conventional substation where the transformer 1 and the reactor 2 are installed, the heat exchangers 1a to 2b, which are installed exclusively for the transformer 1 and the reactor 2, respectively, handle the maximum heat generated by each equipment. Although a capacity to cool the heat loss is required, the reactor 2 is operated only when the load factor of the transformer 1 is very low and the generated heat loss is very small compared to when the transformer 1 is fully loaded. Nevertheless, the cooling tower 3, which commonly cools the losses generated by both, has a capacity to cool the sum of the maximum heat losses generated by both, and the equipment is not equipped with the actual cooling capacity required. This method has disadvantages such as being unnecessarily large and requiring high equipment costs.

This invention was made in order to eliminate the drawbacks of the above-mentioned conventional equipment, and it is used as a control tower to generate heat generated by both the oil-filled transformer and the oil-filled reactor under load conditions that require operation of the oil-filled reactor. It is possible to downsize the cooling tower by using a cooling tower that has enough cooling capacity to cool either the sum of the losses or the heat loss that would occur if each of the above devices were operated independently, whichever is greater. The purpose of this invention is to provide a cooling device for substation equipment with low equipment cost.
