When cabinet machine when work against the wind, wind energy just enters the first air compartment 7 from 2 air intake windows 1 of front lower place; Wind enters the first air compartment 7 backward upper flowing, and sees through bottom screen pack 4 and enters the second air compartment 8, under the stopping of the first deep bead 5, forces wind energy upwards to enter in the transformer coil 10 from the circular hole in the middle of the first deep bead 5; The second deep bead 6 is the same with the effect of the first deep bead 5, forces wind to flow from transformer coil, thereby takes away the heat in the coil; Last wind flows out from the transformer coil top, by cabinet against the wind machine 3 extract cabinets out, realized the heat radiation to transformer coil;

Because 7 pairs of wind that enter of the first air compartment have the effect of assembling and cushioning, and bottom screen pack 4 Area comparisons at the first air compartment 7 tops are large, thereby reduced to enter on the wind direction pressure of transformer room, the dusts of carrying secretly in the wind like this etc. are difficult for upwards seeing through bottom screen pack 4, entering top transformer room, most of dust just rests on the base plate of the first air compartment 7, dust enters transformer inside in the minimizing wind, has alleviated the impact of dust on transformer;

The effect of described adjustment window 2 is the temperature of regulating transformer coil, because wind flows into from the transformer coil bottom, flows out from top winding, so the top winding temperature can occur than the phenomenon of bottom coil temperature drift; The function of adjustment window 2 is exactly different according to transformer coil bottom and head temperature, makes a part of wind from adjustment window 2 directly enters the coil on transformer top, flow out from the blower fan of top, so directly is that top winding is dispelled the heat; The draught area of adjustment window 2 can be adjusted according to the temperature of transformer coil each several part;

Described air intake window 1 is installed on the cabinet front lower place, and bottom screen pack 4 also can by open air intake window 1, be extracted filter core out and be changed or the cleaning and filtering sponge; Adjustment window 2 also is to operate in front.Therefore, cabinet has been realized single-sided operation, and when laying the transformer cabinet, wall can be leaned in transformer cabinet back, has therefore saved the space of laying and operating.

Advantage of the present utility model and beneficial effect: the utility model is because employing is installed into the air regulator mouth at cabinet front lower place single face, reload temperature is regulated the methods such as window, so that transformer dispels the heat evenly, alleviates the dust impact, has saved installation and operating space.
