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. 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) higher, and secondary load (Z) meters, relays, transmitters and other current coil in series to form a closed loop, since the primary winding and the secondary winding have equal ampere turns transformer, I1N1 = I2N2, current transformer rated current load impedance is small than the actual operation of the current transformer, the secondary winding high voltage transformer close to a short Fuzhou, the equivalent of a short circuit operation of the transformer. Multi-tap current transformers. This type of current transformer high voltage transformer Dongguan, Nanning constant high voltage transformer primary winding, the secondary winding is wound, the increased number of taps, to obtain a plurality of different ratios. It has a core and a fixed number of turns of the primary winding, its secondary winding with insulated copper wire wound around the suit on the core insulation tube, the secondary winding tap different ratios leads, terminals connected to base, Each tap set their own terminals, thus forming a plurality of variable ratio, the advantages of such a current transformer is based on the load current ratio, change the secondary wiring terminals to change ratio, without the need to replace the current transformers, to use more convenient. Zhumadian high voltage transformers, transformers, power is supplied by the Xi'an Huayi Huayi power plant. Xian Huayi power plant (www.xahy.com) strong, credible, in Xi'an high-voltage circuit breakers and other industry has accumulated a large number of loyal customers.
