Product DescriptionFor 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.A. voltage

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 N2V2, 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 efficiencyFeatureIn 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 transformerThe
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!Changzhou
