Further, described ventilating duct (2) generally Long Circle, wraps up transformator (1) three-phase coil A phase, B phase, C phase Including.This structure can make intake reach optimal, and wind speed is maximum, so that heat dispersion reaches optimal.
Further, described folder (6) is divided into upper clamping piece (11) and lower clamping piece (12), containing insulated support on folder And cross-over block (7) (5).
Further, described upper clamping piece (11), lower clamping piece (12), insulated support (5) and cross-over block (7) are used for fixing Ventilating duct (2).
Further, before and after cabinet (3), side lower part all has air inlet (13).Air inlet guarantees that its ventilation and heat is musted The air quantity of palpus.
Beneficial effect: compared with prior art, a kind of transformator air channel structure of the present invention has the advantage that the present invention There is provided a kind of transformator air channel structure, by transformator, ventilating duct, the outside cabinet of transformator and the centrifugal fan structure at cabinet top Become the cooling system of transformator;Between ventilating duct and low-voltage coil, between high-tension coil and low-voltage coil, high-tension coil and ferrum Three ducting systems are formed respectively so that this transformator air channel structure send wind concentration, and air quantity is powerful, its radiating effect between the heart Improve 1.5~2 times than original structure, substantially increase the heat dispersion of product, improve the service life of product;And this Bright simple in construction, easy to assembly, preferably fixed ventilating duct by folder, make ventilating duct ventilate more stable, more smooth and easy, enhance The competitiveness of product in market.
Operation principle: transformator runs, the top centrifugal fan starting operation of cabinet, forms air-flow, produces blast, makes Air outside cabinet is entered cabinet endlessly by the air inlet of cabinet front/rear door bottom, at the work of ventilating duct (Long Circle) Under with, air quantity compare concentration by coil bottom, air flue, low-voltage coil (outside) and the ventilating duct between high-voltage coil and low-voltage coil Between air flue and high-tension coil and iron core between air flue, in transformator running produce substantial amounts of heat by cabinet Top centrifugal fan air inlet release, in the way of 90 ° of angles, hot-air is thrown away outside cabinet.
