Transformer, a kind of static electric
appliance applying electromagnetic induction principle to transform alternating
current, is primarily composed of primary winding, secondary winding and iron
core or magnetic core. Commonly, transformer can alter secondary voltage by
altering secondary winding numbers but not permitted power of load consumption.
In the real life, transformer is extensively applied in electrical system and
electronic circuit, usually Modem
Transformers. Also, it is indispensible in measuring system such as
Watt-Hour meters. From the aspect of function, it mainly includes voltage
conversion, current exchanging, impedance transformation, insulation and
voltage stability.
Firstly, voltage conversion
Transformer will be the component of
conversing voltage. In the real application, we often need to change voltage of
alternating current to cater to various various requirements. For examples,
high-rating generator generates alternating present with voltage of tens of
millions volt, and long-distance electricity transmission requires high voltage
of more than hundreds of millions volt. House appliances like bulb, electric
cooker and Computer require voltages of 220V. Tool machine lighting needs
safety voltage of 36V. As for typical electronic tube filament, it only
requirements low voltage of six.3V. So, all these require transformers provided
by Transformers
Manufacturer to get numerous proper voltages.
Secondly, impedance transformation
Transformer also has the function of
impedance transformation. By taking use of impedance transformation,
transformer enables impedance of circuit each ends to obtain a good match to
obtain the aim of transmitting signal power to the maximum limit. For 1
instance, by transforming antenna impedance, Tv antenna outputting balance
Television signal may be transformed into imbalanced signal to nicely match the
inputting impedance of high tuner after becoming inputted into Tv for
enlargement therapy. For another, impedance transformation of audio outputting
transformer lets higher outputting impedance of audio frequency amplifier well
match that of low amplifier to maximize audio amplifier outputting energy and
minimize the distortion.
Thirdly, daily application
As we know, transformer is a kind of
electric appliance for voltage transformation. It could alter alternating
current power of 1 type voltage and present into that of another kind.
Transformer can be utilized in nearly all electric products because it can
ensure electrical safty. On account of its easy principle, it has different
requirement of winding technique according to various application occasions.
Given a easy example, electric welding machines are exactly Special
Transformers which can turn high voltage into a low one. In alternating
current voltage stabilizer, it adopts the technique of immediately changing
outputting winding numbers to get the aim of adjusting outputting voltage.( Superalloy
