Embodiment
In Fig. 1, steel tubulature type air heat exchanger 1 is processed by the 316L stainless steel, adapts to the FOB requirement of moist and salt fog.It is with the interval of 90o, and at tower drum outer wall, 4 (as shown in Figure 2) installed in the top of tower tube door.Current transformer and transformer are installed in the layering of tower tube inner bottom part, and transformer is placed on the ground floor platform, and current transformer is at second layer platform, and ground floor platform plane 15m off sea is high.The outlet of steel tubulature type air heat exchanger 1 cooling pipe is connected with an inlet of an electric T-shaped valve 2 in tower tube door gets into the tower tube through pipeline; The outlet of electric T-shaped valve 2 is connected with the inlet of main circulation pump 3 with spare circulating pump 4; Be provided with unidirectional valve 5 between the outlet of main circulation pump 3 and subsequent use circulation 4 and the electric heater 7; The one-way flow of unidirectional valve 5 may command cooling fluids makes cooling fluid flow along same direction.Electric heater 7 is connected with current transformer internal exchanger 9 through flow control valve 8; The pipeline that links to each other with current transformer internal exchanger 9 is divided into two-way; One the tunnel connects transformer internal exchanger 11; Another road is divided two-way through flow control valve 10 again after 11 outlets of transformer internal exchanger converge, the one tunnel is connected to tower tube outer steel tubulature type air heat exchanger 1 through tower tube door enters the mouth, and another road is connected to another inlet of electric T-shaped valve 2.Between porch, unidirectional valve 5 and the heater 7 of circulating pump 3, between current transformer 13 and the transformer 14, internal exchanger 11 exits in the transformer 14 and coolant circulation system outlet and porch be respectively arranged with some break valves 6.
Circulating pump 3 orders about cooling fluid at coolant circulation system and be used for circulation between the air radiator 1 of cooling fluid heat radiation.Cooling fluid from circulating pump 3 through electric heaters 7 (not working) at electric heater under the cooling situation after the internal exchanger 9 through current transformer 13 at first; Absorb heat the deionized water that cooling fluid circulates in current transformer 13 internal exchangers; Leave after the current transformer 13; Cooling fluid shunting two-way, one road internal exchangers 11 of flowing through in the transformer 14 are taken away the heat in the transformer internal exchanger insulating oil.Another road is converged in transformer heat exchanger 11 outlets through flow control valve 10 and last road cooling fluid, from the outside of tower tube 12, flows to 4 steel tubulature type air water heat exchangers of tower tube 12 outsides of installing.Behind tower tube extraneous air heat exchanger cold 1, can obtain the cooling fluid of temperature up to specification, flow to circulating pump 3 through electric T-shaped valve 2 at last.So circulation realizes taking the heat of current transformer and transformer to tower tube 12 outsides.When detecting current transformer 13 with transformer 14 ambient temperatures when very low; Control system will be controlled electric T-shaped valve 2 and open to transformer internal exchanger 11 Way outs; Make the cooling fluid tower tube 12 air outside heat exchangers 1 of not flowing through; And while opening electric heater 7 heated cooling fluids, realize heating to transformer and current transformer.
Above embodiment only supplies to explain the usefulness of the utility model; But not to the restriction of the utility model; The technical staff in relevant technologies field under the situation of spirit that does not break away from the utility model and scope, can also make various conversion or modification; Therefore all technical schemes that are equal to also should belong to the category of the utility model, should be limited each claim.
