Product Description
For different types of transformer has the corresponding technical requirements, available corresponding technical parameters. Power transformer main technical parameters such as: rated power, rated voltage and the voltage, rated frequency, temperature level, temperature, voltage adjustment rate, insulation and moisture-proof performance, for frequency transformer of the main technical parameters is: voltage ratio, frequency characteristics of the nonlinear distortion, magnetic shielding and electrostatic shielding efficiency.

Two groups of coil windings, respectively, the number of N1 and N2, N1 is primary, N2 is the secondary. The primary coil and an AC voltage, induction electromotive force generated in the secondary coil ends will. When N2>N1, the induction electromotive force to even higher than primary and voltage, the transformer known as step-up transformer: when N2<N1, the induced electromotive force below the primary voltage. The transformer is said to reduce transformer. Primary secondary voltage and the coil number has the following relationship:
The n is called the voltage ratio (the ratio of the n<1), the N1>N2, the V1>V2, the transformer is the buck transformer, the other is the boost transformer.
Efficiency of B. transformer:
At the rated power, the transformer's output power and the ratio of the input power, called the transformer's efficiency
Feature
In 7 / as the efficiency of the transformer; P1 power input, P2 output power.
When the transformer output power of P2 is equal to the input power P1 and efficiency ETA equal to 100%, transformer, will not generate any loss. But in fact, the transformer is not. When the total transmission power transformer to generate losses, such losses mainly copper loss and iron loss.
Power of C transformer
The transformer core flux and the applied voltage. The excitation current in the current will not increase with the increase of the load.. Although the increase in the core is not saturated load will make the resistance loss of the coil increased more than nominal capacity due to coil to generate heat can not be timely shed, the coil can damage, if you use the coil is formed by a superconducting materials, current increases will not cause fever, but inside the transformer and magnetic flux leakage caused by impedance, but current increases, the output voltage will drop and current increases, the output voltage lower, so the transformer output impossible is infinite. If you say no, transformer impedance, then when the current flowing through the transformer will have a particularly large electric power, it is easy to damage the transformer coil, although you have a power transformer but not. It can be said that with the development of superconducting material and core material, the output power of the transformer with the same volume or weight will increase, but not infinite!
