Transformer, a type of static electric
appliance applying electromagnetic induction principle to transform alternating
current, is mainly composed of primary winding, secondary winding and iron core
or magnetic core. Generally, transformer can change secondary voltage by
altering secondary winding numbers but not permitted power of load consumption.
In the genuine life, transformer is extensively applied in electrical method
and electronic circuit, typically Modem
Transformers. Also, it's indispensible in measuring system such as
Watt-Hour meters. In the aspect of function, it mainly consists of voltage
conversion, current exchanging, impedance transformation, insulation and
voltage stability.
Firstly, voltage conversion
Transformer will be the element of
conversing voltage. In the genuine application, we often need to change voltage
of alternating current to cater to numerous different requirements. For
examples, high-rating generator generates alternating current with voltage of
tens of millions volt, and long-distance electrical energy transmission demands
higher voltage of more than hundreds of millions volt. Home appliances like
bulb, electric cooker and Pc require voltages of 220V. Tool machine lighting
needs safety voltage of 36V. As for common electronic tube filament, it only
needs low voltage of six.3V. So, all these need transformers provided by Transformers Manufacturer
to get numerous correct voltages.
Secondly, impedance transformation
Transformer also has the function of
impedance transformation. By taking use of impedance transformation,
transformer enables impedance of circuit both ends to obtain a great match to
get the aim of transmitting signal energy to the maximum limit. For one
instance, by transforming antenna impedance, Tv antenna outputting balance Tv
signal can be transformed into imbalanced signal to nicely match the inputting
impedance of higher tuner after becoming inputted into Television for
enlargement therapy. For an additional, 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 really a kind of
electric appliance for voltage transformation. It can change alternating
present energy of one type voltage and present into that of an additional kind.
Transformer may be used in almost all electric products since it could make
sure electrical safty. On account of its simple principle, it has different
requirement of winding technique based on different application occasions.
Offered a simple example, electric welding machines are exactly Special
Transformers which can turn higher voltage into a low 1. In alternating
current voltage stabilizer, it adopts the technique of instantly altering
outputting winding numbers to get the aim of adjusting outputting voltage.( Superalloy
