THREE WINDING TRANSFORMER WITH MAGNETIC SHUNT ALTERNATING CURRENT FOR NO-BREAK POWER UNIT

摘要

PURPOSE:To manufacture the three winding transformer with magnetic shunt for AC no-break power unit which has a natural cooling and a high capacity without providing a forced cooling method by dividing a coil of three winding transformer into two parts and winding them on a core type iron core. CONSTITUTION:After a core type iron core 19G of the three winding transformer with a magnetic shunt is formed into a circle, a pair of feet 19J to wind each first coil to third coil, 19A-19C, are provided. After the feet 19J are divided into three regions by a magnetic shaft 19S, the first coil to the third coil, 19A- 19C, are divided and wound around each region. By dividing and winding the first coil to the third coil, 19A-19C, divided thus, the three winding transformer with a magnetic shunt for AC no-break power unit which has a natural cooling and a high capacity is easily manufacture without providing any forced cooling method.
