ZIGZAG Y TYPE THREE-PHASE FOUR-WIRE TRANSFORMER FORMED WITH DOUBLE WIRE TO REMOVE HARMONICS

摘要

PURPOSE: A zigzag Y type three-phase four-wire transformer formed with a double wire to remove harmonics is provided to form three intersection points and reduce the no-load loss by connecting two wires to each phase. CONSTITUTION: An end portion of a blue line of an R phase is connected to an end portion of a blue line of an S phase. An end portion of a black line of the S phase is connected to an end portion of a black line of a T shape. An end portion of a red line of the R phase is connected to an end portion of a red line of the T phase. Two wires of the R phase are connected to the S phase and the T phase through a steel core of a core type three-phase transformer. Two wires of the S phase are connected to the T phase and the R phase through the steel core of the core type three-phase transformer. Two wires of the T phase are connected to the R phase and the S phase through the steel core of the core type three-phase transformer.
