Structure principle

The high voltage voltage of this series of products is generally 6kV, 10kV, 35kV; the low voltage voltage is generally 0.66 kV, 0.4 kV, 0.315 kV, 0.27 kV. The connection group is D, do, y11 or D, y11, do. The transformer is connected to an external rectifier to provide 12-pulse DC power supply for the equipment. This kind of transformer is required to run through or half through. In order to ensure that the short-circuit impedances of the two low-voltage coils to the high-voltage coil are approximately equal, the high-low-voltage coil adopts a shaft bidirectional split structure. )Corresponding.


In this way, the high and low voltage coils are distributed evenly along the axial magnetic potential, which can greatly reduce the electromotive force during a short circuit. Thereby improving its ability to withstand sudden short circuits.

The high voltage coil is an epoxy resin cast coil, and the low voltage is a foil coil structure. One set of low voltage leads is drawn from the upper side, and a set of leads is drawn from the lower side. This series of products has been

successfully connected to the network and is operating in good condition.
