Abstract
The utility model discloses an auxiliary transformer cabinet for an electric locomotive. In order to solves problems that the auxiliary transformer cabinet for the electric locomotive in the prior art occupies too large area and is not beneficial for uniform radiation, the auxiliary transformer cabinet for the electric locomotive of the utility model is provided. The auxiliary transformer cabinet for the electric locomotive comprises a cabinet body. A plurality of auxiliary transformers are arranged within the cabinet body and are arranged in a staggering manner from top to bottom. A ventilator for feeding air into the plurality of auxiliary transformers is positioned on the upper part of the cabinet body. The air outlet of the ventilator communicates with the air inlet of the cabinet body. The auxiliary transformer cabinet for the electric locomotive satisfies requirements of arrangement of a high-power AC drive six-axis 7200kW electric locomotive and satisfies the radiation requirement of the auxiliary transformer.
Description
Technical field
The utility model relates to electric locomotive ventilation cooling field, is specially a kind of auxiliary transformer for electric engine cabinet, is particularly useful for six 7200kW(plateaus of high power AC transmission) electric locomotive.
Background technology
The mode of two auxiliary transformers of electric locomotive auxiliary transformer cabinet installation both at home and abroad is that horizontal Tile arranges that the locomotive overall length's director space that takies is bigger at present.The draft type of auxiliary transformer cabinet is essentially the car external air inlet simultaneously, and level enters between locomotive machinery behind the cooling auxiliary transformer, and this air flow is little to the uniformity influence of air quantity, and air quantity controller is not installed in the cabinet.Because the draft type of auxiliary transformer cabinet is the car external air inlet, vertically be discharged at the bottom of the car behind the cooling auxiliary transformer, if there is not air quantity controller, then the air quantity on cabinet top is close to nothing, is unfavorable for the heat radiation of top auxiliary transformer.According to six 7200kW(plateaus of high power AC transmission) the electric locomotive arrangement requirement, the overall width of cabinet can not surpass 1200mm, and the width dimensions of separate unit auxiliary transformer is about 886mm, arranges that according to the horizontal Tile of routine two auxiliary transformers can not satisfy space requirement so.
The utility model content
Big with auxiliary transformer cabinet floor space in order to overcome the existing power locomotive, and the deficiency that is unfavorable for Homogeneouslly-radiating, the utility model aims to provide a kind of auxiliary transformer for electric engine cabinet, many auxiliary transformer mounting meanss are vertically superposed layout in this transformer case, and the air quantity of many auxiliary transformers is kept uniformity substantially.
To achieve these goals, the technical scheme that adopts of the utility model is:
A kind of auxiliary transformer for electric engine cabinet, comprise the cabinet with air inlet and air outlet, its design feature is, be furnished with many auxiliary transformers in the described cabinet, many auxiliary transformers are vertically stacked from top to bottom, be equipped with to the ventilation blower of many auxiliary transformer air feeds on the top of described cabinet, and the air outlet of this ventilation blower is communicated with the air inlet of described cabinet.
Below be the technical scheme of further improvement of the utility model:
Before making the cooling air discharge at the bottom of the car, change the air-flow trend, the bottom of described cabinet is provided with the air quantity controller of regulating auxiliary transformer forced ventilation amount, this air quantity controller can adopt existing blast volume controller, thereby the air velocity that makes cabinet inside keeps evenly substantially, has guaranteed to keep uniformity substantially by the air quantity of auxiliary transformer.Further, described air quantity controller is the baffler that is arranged on cabinet air outlet the place ahead.
As a kind of concrete version, be furnished with the auxiliary transformer of two vertically stacked in the described cabinet, an auxiliary transformer is positioned on another auxiliary transformer, can reduce to take up an area of the space thus.
According to embodiment of the present utility model, described cabinet air outlet is arranged on the cabinet bottom; Described cabinet air inlet is arranged on the cabinet top, thus, ventilation blower is introduced wind outside the cabinet top, and the wind behind the cooling auxiliary transformer is discharged from the cabinet bottom, realize air flow path earlier vertical, after laterally, the vertical movement locus that flows again, thereby realize abundant cooling to auxiliary transformer.
Compared with prior art, the beneficial effects of the utility model are: the utility model satisfies six 7200kW(plateaus of high power AC transmission) the general layout requirement of electric locomotive, satisfy the heat radiation requirement of auxiliary transformer, particularly:
1) a plurality of auxiliary transformers of vertically superposed layout in the auxiliary transformer cabinet, compact conformation, the integrated level height has reduced installation space greatly.
2) air quantity controller novel structure, compactness in the auxiliary transformer cabinet, windage is little, has both guaranteed the uniformity of the inner air quantity of cabinet, and the power of ventilation blower need not increase too big again.
Below in conjunction with drawings and Examples the utility model is further elaborated.
Description of drawings
Fig. 1 is the structure principle chart of an embodiment of the utility model.
In the drawings
The 1-ventilation blower; The 2-cabinet; 3,4-auxiliary transformer; The 5-air quantity controller.
Embodiment
A kind of auxiliary transformer for electric engine cabinet comprises the cabinet 2 with air inlet and air outlet, two auxiliary transformers 3,4 is integrated in the cabinet 2, and it is carried out the forced ventilation cooling.The cabinet of auxiliary transformer cabinet is welded steel structure, and cabinet top arranges that 1 ventilation blower 1 is used for forced ventilation, and two auxiliary transformers are vertically superposed to be fixed as an integral arrangement in cabinet, has reduced the cabinet overall width greatly.The cooling principle of the utility model auxiliary transformer cabinet is: the car outer air enters in the cabinet after pressurizeing by auxiliary transformer cabinet ventilation blower, after air-flow transfers two auxiliary transformers of horizontal direction cooling to by vertical direction, vertically be discharged to outside at the bottom of the car from the exhaust outlet of cabinet front portion.
For satisfying the heat radiation requirement of auxiliary transformer, the cabinet indoor design a kind of air quantity controller 5, the preceding air-flow that changes moves towards at the bottom of making the cooling air discharge car, thereby the air velocity that makes cabinet inside keeps evenly substantially, has guaranteed to keep uniformity substantially by the air quantity of upper and lower two auxiliary transformers.
The content that above-described embodiment is illustrated should be understood to these embodiment and only is used for being illustrated more clearly in the utility model, and be not used in the restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims institute restricted portion to the modification of the various equivalent form of values of the present utility model.
