<p>The invention provides a cooling device of a transformer, and the cooling device can effectively cool the transformer with simple structure. The cooling device of the transformer comprises a frame body (1) for storing the transformer (2); a first separating plate (6) which divides the periphery of the transformer into a front part and a rear part inside the frame body, and forms a first air channel (7) at the back side of the transformer; top fans for venting (8a, 8b) opposite to the first air channel (7) and arranged above the frame body; cooling air intake ports (4a, 4b) formed at a position which is at the front of the frame body and opposite to a base part (2a) of the transformer; and a second separating plate (10) which divides the cooling air intake ports up and down and separates the periphery of the transformer at the base side of the transformer. The following air channels are formed: a second air channel passing through the lower part of the second separating plate via the cooling air intake ports; a cooling air channel passing through a winding part of the transformer and then through the first air channel to arrive the top fans for venting; and a cooling air channel passing through intervals among the winding parts of the transformer via the cooling air intake ports to arrive the first air channel.</p> |
