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 10):
A method of winding a dry-type transformer coil, comprising following steps:\n (1) winding an inner coil of a first layer of pancake coils around an inner cylinder, providing a second spacer block at an end of the inner coil of the first layer of pancake coils for separating the inner coil of the first layer of pancake coils from an inner coil of a second layer of pancake coils, and winding the inner coil of the second layer of pancake coils around the inner cylinder; (2) winding an inner coil of a further layer of pancake coils in a similar manner as the previous step until an inner coil of a last layer of pancake coils has been wound; (3) providing a first spacer block at a side of the inner coil of each layer of pancake coils for separating the inner coil from an outer coil; (4) winding an outer coil of the first layer of pancake coils around the first spacer block, forming a first air passage between the inner coil of the first layer of pancake coils and the outer coil of the first layer of pancake coils, providing a third spacer block at an end of the outer coil of the first layer of pancake coils for separating the outer coil of the first layer of pancake coils from an outer coil of the second layer of pancake coils, winding the outer coil of the second layer of pancake coils around a further first spacer block, forming a further air passage between the inner coil of the second layer of pancake coils and the outer coil of the second layer of pancake coils, and forming a second air passage between the inner coil of the first layer of pancake coils and the inner coil of the second layer of pancake coils, and between the outer coil of the first layer of pancake coils and the outer coil of the second layer of pancake coils; (5) winding an outer coil of a further layer of pancake coils in a similar manner as the previous step until an outer coil of the last layer of pancake coils has been wound; and (6) connecting a tail end of the inner coil of the first layer of pancake coils with a head end of the outer coil of the last layer of pancake coils via a lead.
