Structure principle

he high voltage of this series of products is generally 6kV, 10 kV and 35 kV; low voltage is generally 0.66 kV, 0.4 kV, 0.315 kV and 0.27kv.The low-voltage coil has two groups of outgoing lines, one group is connected into y pattern and the other group is connected into d pattern. Its connection groups are D, do, y11 or D, y11, do. The external rectifier of the transformer provides 12-pulse DC power for the equipment. This kind of transformer requires either traversing or semi-traversing operation. To ensure that the short-circuit impedance of the two low-voltage coils to the high-voltage coil is approximately equal, the high-voltage coil and the low-voltage coil adopt an axial bidirectional split structure, in which each half of the high-voltage coil corresponds to the corresponding low-voltage coil (d or y).

In this way, the magnetic potential distribution of high and low voltage coils is balanced along the axial direction, which can greatly reduce the electric power during short circuit, thus improve that capability of resisting sudden short circuit.

The high-voltage coil is an epoxy resin cast coil, and the low voltage is a foil coil structure. A group of low-voltage leads are led out from the upper side and another from the lower side. The series of products have been successfully put into operation and are in good condition.
