Title: Transformer
Inventor: HOSHI MINORU
IPC: H01F29/02
Filed: 1978-06-28
Abstract: PURPOSE:For reducing a transformer tank in size and in oil capacity, to provide cocentrical tap windings on a iron core leg in the vicinity of the upper and lower ends of the space between the low- and high-voltage coils made by winding wire round said iron core leg. CONSTITUTION:Generally, the distance d between the high- and low-voltage coils 3 and 2 of a transformer is determined by two requirements. One of said requirements is %-impedance alphad/H wherein H is the height of coils. The other is the average field strength V/d wherein V is the maximum value obtained of the voltage differential of the portion in low- and high-voltage coils of potential distribution in coils at a high-voltage line terminal 5 in insulation test. Said distance d is required to be fixed because of the restriction of said field strength, but to be increased further due to the restriction of %-impedance. Therefore, the tap coil 4 usually provided outside said high-voltage coil 3 is placed between said low- and high-voltage coils 2 and 3, and said requirements are satisfied. At the same time, a container is reduced in size.
