Description
Technical field
It the utility model is related to one kind, more particularly to a kind of fan of dry type transformer cooling device.
Background technology
Dry-type transformer is typically all installed in box power transformation box at present, and running environment is poor compared with severe and radiating condition, is done
Formula transformer is typically necessary installation cooling blower, and the automatic forced air cooling under setting state is realized by temperature controller,
Accelerate air circulation, to strengthen the heat dispersion of dry-type transformer and overload capability, so as to protect the safety of power transformer product
Reliability service.
Existing cross-flow fan air quantity is smaller, and in the box type transformation case, needs transformer to stop during more ventilating fan
Electricity, certain economic loss is brought to user, and due to the skyborne debris that largely suspends, time length in external environment condition be present
Cause the accumulation of debris in power transformation box, be less useful for the radiating of coil, and indoor power transformation box due to blower fan sound it is big, to outside
Environment causes certain noise pollution.
Utility model content
Technical problem to be solved in the utility model is：A kind of fan of dry type transformer cooling device is provided, solved
Existing cross-flow fan air quantity is smaller, needs transformer to have a power failure during more ventilating fan, exists in external environment condition and is largely suspended in sky
In debris, cause the accumulation of debris in power transformation box, be unfavorable for the radiating of coil, blower fan sound is big, and one is caused to external environment condition
The problem of fixed noise pollution.
The utility model is to solve the problems, such as that used technical scheme set forth above is：
A kind of fan of dry type transformer cooling device, cabinet 1 is interior to set coil 2, iron core 3, and the bottom of coil 2 sets iron core 3,
The bottom of iron core 3 sets lower clamping piece 4, including cabinet 1, vortex fan 5, ventilation duct A6, ventilation duct B9, connecting cavity 7 and Air Filter 8,
It is symmetrical arranged vortex fan 5 on the lower sides of cabinet 1, the both sides of lower clamping piece 4 are symmetrical arranged ventilation duct A6, on ventilation duct A6 lateral walls
Air vent 10 uniformly is opened up, and ventilation duct A6 outer ends are connected with the madial wall of cabinet 1, and ventilation duct B9 is also set up in ventilation duct A6, are led to
Airduct B9 outer ends are connected with the air outlet of vortex fan 5, and connecting cavity 7, connecting cavity are also set up between vortex fan 5 and ventilation duct B9
Air Filter 8 is set in 7.
The described insertion of Air Filter 8 is arranged in connecting cavity 7, and the upper end of Air Filter 8 sets drop handle 11, convenient not stop whirlpool
In the case of flow fan, dust on Air Filter or cleaning Air Filter is changed in time.
Described air vent 10 is respectively positioned on the rear portion of ventilation duct B9 gas outlets, has more preferable erasure effect.
The beneficial effects of the utility model are：1st, the transformer suitable for needing Wind Volume to be cooled down under adverse circumstances
Or require that transformer is changed in the case where not powering off to blower fan, relative to cross-flow fan, eddy current type fan delivery
Greatly, along with ventilation duct A, ventilation duct B drainage, therefore good cooling results.2nd, eddy current type fan life is grown, more suitable for disliking
Worked under bad environment, eddy current type assembling is external in transformer case, therefore does not need transformer to have a power failure during more ventilating fan, reduces
Transformer has a power failure the economic loss brought, and it is reliable to change fan safe, improves efficiency, can more intuitively to blower fan
It is monitored.3rd, the combination of Air Filter and noise elimination structure is employed, not only with dust-proof effect, and erasure effect is notable, no
Noise pollution can be caused.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein, 1- cabinets, 2- coils, 3- iron cores, 4- lower clamping pieces, 5- vortex fans, 6- ventilation duct A, 7- connecting cavity, 8- prevent
Dirt net, 9- ventilation duct B, 10- air vent, 11- drop handles.
Embodiment
Embodiment of the present utility model is further illustrated below in conjunction with the accompanying drawings.
Reference picture 1, a kind of fan of dry type transformer cooling device described in present embodiment, cabinet 1 is interior to set line
Circle 2, iron core 3, the bottom of coil 2 set iron core 3, and the bottom of iron core 3 sets lower clamping piece 4, including cabinet 1, vortex fan 5, ventilation duct
A6, ventilation duct B9, connecting cavity 7 and Air Filter 8, vortex fan 5 are symmetrical arranged on the lower sides of cabinet 1, the both sides of lower clamping piece 4 are symmetrical
Ventilation duct A6 is set, air vent 10 is uniformly opened up on ventilation duct A6 lateral walls, and ventilation duct A6 outer ends connect with the madial wall of cabinet 1
