High voltage transformers are suitable for 1kv to 220kv power system will be a large voltage into a small voltage or high current in order to convert the small current measurement, protection, transformer high voltage transformer used generally divided 3kv, 6kv, 10kv , 35kv, 66kv, 110kv, 220kv, 24kv system in Jiangsu Province is now the trial. 10kv and 220kv among the most widely used. The second input of 200V or 100V or more 5A or 1A. Common current transformer principle structure: The structure is simple current transformer, a primary winding insulated from each other, the secondary winding, the core and the frame, housing, terminals, etc. It works basically the same with the transformer primary winding turns (N1) less Jiaxing high voltage transformers, power lines directly connected in series Wenzhou high voltage transformers, a load current (I1) through the primary winding inductance Hangzhou high voltage device, alternating magnetic flux induced by the secondary current (I2) reduced proportionately; secondary winding turns (N2) more, and meters, relays, transmitters and other current coil secondary load ( Z) in series to form a closed circuit, since the primary winding and the secondary winding have equal ampere turns, I1N1 = I2N2, current transformer rated current than the load impedance of the current transformer is very small in the actual operation, close to a short secondary winding, equivalent to a short circuit transformer run. Wenzhou high voltage transformer, Huayi Electric Power (certified), high voltage transformers supplied by Xian Huayi power plant.
