THREE PHASE GROUNDING TRANSFORMER
Product Introduction
This type of transformer adopts Z-type wiring (or zigzag wiring). The difference between this type of transformer and ordinary transformer is that each phase coil is divided into two groups and wound reversely on the magnetic column of this phase. The advantage of this connection is that the zero sequence magnetic flux can flow along the magnetic column, while the zero sequence magnetic flux of ordinary transformer flows along the magnetic leakage circuit. Therefore, the zero sequence impedance of Z-type grounding transformer is very small (about 10Q), while that of ordinary transformer is much larger. According to the regulations, the capacity of ordinary transformer with arc suppression coil shall not exceed 20% of the transformer capacity. Type z transformer can be equipped with arc suppression coil with capacity of 90%~100%. In addition to arc suppression coil, A grounding transformer can also be equipped with a secondary load, which can replace station transformer, thus saving investment cost.
