Abstract
PURPOSE:To shorten insulating size between a high-tension winding and a low-tension winding while reducing the usage of an insulating material by arranging a sheet-shaped conductor connected to a line terminal for the high-tension winding and an insulator insulating said conductor to the high and low-tension windings between at least the high-tension winding and the low-tension winding. CONSTITUTION:A sheet-shaped conductor 14 connected to a line terminal U for a high-tension winding 12 and insulators 15, 16 insulating the conductor 14 to high and low-tension windings 12, 13 are mounted between the high-tension winding 12 and the low-tension winding 13. Consequently, the potential of the conductor 14 is made the same as that of the line terminal U, and potential difference between the conductor 14 and a neutral point terminal X and between the conductor 14 and the low-tension winding 13 is brought to approximately 100%. As a result, when applied impulse voltage is brought to 150kV, each thickness size t1, t2 of the insulators 15, 16 disposed among the conductor 14 and the high and low-tension windings 12, 13 is brought respectively to approximately 20mm. Accordingly, insulating size between the high-tension winding 12 and the low-tension winding 13 is brought to approximately 40mm in total because the conductor 14 is extremely thin, thus making the insulating size shorter than conventional examples by approximately 20mm.
