Common current transformer principle structure: The structure is relatively simple current transformer high-voltage transformer Nanning, insulated from each other by a primary winding, a secondary winding, the core and the frame, housing, terminals, etc. Its working principle is basically the same transformer, the number of turns of the primary winding (N1) is less, the power supply line directly connected in series, a load current (I1) through the primary winding, the resulting alternating magnetic flux is induced decrease proportionally secondary current (I2); number of turns of the secondary winding (N2) of more transformers, and the secondary load (Z) meters, relays, transmitters and other current coil in series to form a closed loop, since the primary winding and the secondary windings have equal ampere turns Guangzhou high voltage transformers, I1N1 = I2N2 Dongguan high-voltage transformers, current transformers rated load impedance is small than the actual operation of the current transformer secondary winding is close to a short, running the equivalent of a short circuit transformer. In AC circuits, commonly used high-voltage transformer to convert low voltage, high current into a small current, after which for measurement, control and protection. This will not only increase the measuring instrument from the process, to facilitate standardized instrument to reduce control, protection of voltage and current of the device, and the instrument and equipment or high voltage circuits are separated to ensure the safety instruments, equipment and staff.
