high voltage Transformer is a type of transformer suitable for converting large voltage into small voltage or large current into small current in 1kV to 220kV power systems for measurement, protection, and use. It is generally divided into 3kV, 6kV, 10kV, 35kV, 66kV, 110kV, and 220kV. The 24kV system is currently being tested in Jiangsu region.
Among them, 10kV and 220kV are the most widely used. The secondary input is mostly 200V or 100V, 5A or 1A.
Classification:
