Abstract:
A dry-type transformer coil and a method of winding a dry-type transformer coil are disclosed. An inner coil of pancake coils is separated from an outer coil of pancake coils by a first spacer block, to form a first air passage. Respective inner coils of adjacent two layers of pancake coils are separated from each other by a second spacer block, and respective outer coils of the adjacent two layers of pancake coils are separated from each other by a third spacer block, to form a second air passage. The first air passage cooperates with the second air passage, so that heat caused by operation of pancake coils can be effectively and quickly dissipated, thereby improving operational reliability of the dry-type transformer coil and increasing service life of the dry-type transformer coil. Compared with a conventional dry-type transformer coil, the voltage between layers is greatly reduced.

Claim (Index 1):
A dry-type transformer coil, comprising an inner cylinder and at least two layers of pancake coils, wherein the at least two layers of pancake coils are wound around the inner cylinder sequentially along an axial direction of the inner cylinder, each layer of pancake coils includes an inner coil and an outer coil, the inner coil is separated from the outer coil to form a first air passage, the first air passage is provided with a first spacer block for separating the inner coil from the outer coil, adjacent two layers of pancake coils are separated from each other to form a second air passage, the second air passage is provided with a second spacer block for separating respective inner coils of the adjacent two layers of pancake coils from each other, and a third spacer block for separating respective outer coils of the adjacent two layers of pancake coils from each other, the pancake coils are wound in an order sequentially from the inner coil of the first layer of pancake coils to the inner coil of a last layer of pancake coils, and then sequentially from the outer coil of the first layer of pancake coils to an outer coil of the last layer of pancake coils, and a tail end of the inner coil of the first layer of pancake coils is connected with a head end of the outer coil of the last layer of pancake coils via a lead wire.
