Description
Technical field
The utility model relates to Cooling Technology of Electronic Device field, refers to especially a kind of wind energy turbine set main transformer cooling system.
Background technology
At present, wind energy turbine set main transformer (main transformer) cooling system adopts fan cooled, and when fan control handgrip is got to " manually " position, two groups of fans all move; Fan handgrip is got to " automatically " when position, has two conditions to start fan loops, and one is by transformer load current start, and one is to reach 55 while spending by transformer oil surface temperature, and two groups of fans start together.This just causes wind energy turbine set field power consumption high.
As from the foregoing, two groups of fans of main transformer of at present wind energy turbine set operation are start and stop simultaneously, can not control separately according to on-site actual situations, exist that a power consumption is higher, a power consumption rate relatively also high, be unfavorable for the problems such as wind-powered electricity generation company is energy-saving and cost-reducing.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of wind energy turbine set main transformer cooling system that can avoid two groups of fans start and stop simultaneously of wind energy turbine set main transformer.
For solving the problems of the technologies described above, the utility model provides a kind of wind energy turbine set main transformer cooling system, and its technical scheme is as follows:
A kind of wind energy turbine set main transformer cooling system, comprise that first group of fan, second group of fan, first are controlled handgrip, the first intermediate repeater and at least for measuring the oil temperature of main transformer and the main transformer measure and control device of load current, wherein, also comprise: second controls handgrip, be connected with described second group of fan, for control described second group of fan with manual mode; The second intermediate repeater, is connected with described main transformer measure and control device with described second group of fan, for control described second group of fan according to the load current of main transformer; Described first controls handgrip is connected with described first group of fan, for control described first group of fan with manual mode; Described the first intermediate repeater is connected with described main transformer measure and control device with described first group of fan, for control described first group of fan according to the oil surface temperature of main transformer.
The beneficial effect of technique scheme of the present utility model is as follows:
In such scheme, two groups of fans are controlled respectively, every group of fan has " manually " and " automatically " two kinds of operational modes, wherein temperature actuated by transformer oil surface under one group of " automatically " mode, another group fan is pressed transformer load current start, so just greatly reduce an electricity consumption, and then reduce a power consumption rate.
Accompanying drawing explanation
Fig. 1 is the theory diagram of the utility model embodiment.
Embodiment
For making the technical problems to be solved in the utility model, technical scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The higher problem of field power consumption that the utility model expends for the wind energy turbine set of prior art, provides a kind of wind energy turbine set main transformer cooling system.
As shown in Figure 1, embodiment of the present utility model comprise at least for measuring the temperature of main transformer and the main transformer measure and control device of load current 1, first group of fan 41, second group of fan 42, first control handgrip 21, the first intermediate repeater 22, second is controlled handgrip 31, the second intermediate repeater 32.Wherein, first controls handgrip 21 is connected with first group of fan 41, for control first group of fan 41 with manual mode; The first intermediate repeater 22 is connected with main transformer measure and control device 1 with first group of fan 21, for control first group of fan 21 according to the oil surface temperature of main transformer.Second controls handgrip 31 is connected with second group of fan 42, for control second group of fan with manual mode.The second intermediate repeater 32 is connected with main transformer measure and control device 1 with second group of fan 42, for control second group of fan 42 according to the load current of main transformer.
Be wind-powered electricity generation generating peak period winter, and transformer load is higher, but ambient temperature is lower, as two groups of fans are all got to " automatically " position, after one group of fan of transformer load current start, can meet transformer heat radiation requirement, so another group fan row that just can not put into operation; As temperature of oil in transformer is still very high, reach after definite value, " automatically " position of another group fan is temperature actuated with regard to pressing transformer oil surface so, drops into two groups of fans.Be the low ebb phase of wind-powered electricity generation enterprise generating summer, although ambient temperature is high, transformer load is very little or substantially do not have load, so also need not start two groups of fans.Visible, embodiment of the present utility model, for the operation characteristic of wind energy turbine set, controls respectively two groups of cooling fans.
In sum, two groups of fans of the present utility model " manually " position is realized respectively and being controlled.When " automatically " position, by oil surface temperature, control first group of fan, by second group of fan of transformer load Current Control.Two groups of fans are separately controlled and are made, under different load condition, can meet the requirement of transformer temperature, have saved an electricity consumption, transformer operation is more economical, reliable, farthest saved an electricity consumption, realized cost efficiency, and transformer operation is more stable, reliable.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
