Abstract
PURPOSE: To attain system protection by restricting short-circuit current at the time of failure of a ternary circuit wherein two transformers each having a primary, secondary and ternary windings are commonly used, by connecting in parallel the primary and the secondary windings to use it as a primary winding and using each ternary winding independently.
CONSTITUTION: When two single phase transformers Tr1 and Tr2 having primary windings P1 and P2, secondary windings S1 and S2, and ternary windings T1 and T2, respectively, are used as a single phase transformer, the primary windings P1 and P2 and the secondary windings S1 and S2 are connected in parallel to primary terminals 10, 11 and secondary terminals 12, 13, respectively, to form a primary circuit and a secondary circuit, and then the ternary windings T1 and T2 are individually connected to ternary terminals 14, 15 and 14a, 15a. A large capacity transformer is constructed by disposing the single phase transformers Tr1 and Tr2 on single phase cores such as two-leg core, three-leg core having a side leg and four-leg core or any combination thereof to reduce % impedance between the secondary and the ternary windings by half, thereby restricting the short-circuit current of the ternary circuit.
