Transformer Introduction:
This batch of small substation transformer oil is available in four different capacities. They are 200kVA, 315kVA, 500kVA and 830kVA respectively. Among them, there are 5 units of 200kVA, 3 units of 315kVA, 2 units of 500kVA, and 5 units of 830kVA. The voltage is 11/0.415kv, the cooling method is ONAN, no-load tap changer, and the voltage adjustment range is ±2 * 2.5%. The connection group is Dyn11. The primary side bushing uses a plug-in bushing, and the secondary side uses an epoxy cast bushing. The impedance of these transformers is 4.5%. The transformer of this small substation can be dry type or oil type.
