Product Description
Main
Characteristics:
(1) In medium
frequency machines，parallel oscillating structure is
used . IGBT module power components and our fourth generation
inverting control technologies are applied.
(2) Wide frequency ranges from 1KHZ to *0KHZ, it is
easy to match the machine according to the parts and heating
desire.
(3) Due to the parallel oscillating structure, it is easy
to get the best matching of the machine to get high heating
efficiency and full power output of generator.
(4) Due to the high technologies of our fourth generation
inverting control, soft and accurate switching control is
realized to assure the high reliability and low repair of the
machine.
Advantages and
applications of models with Timer function:
1. Heating power, retaining power, heating time, retaining
time can be preset and adjusted, this makes it
possible to control the heating curve and heating time.
2. It is suitable to use in the repeated heating or high
speed heating of small parts;
3. By presetting the timer and the power of the generator,
retaining can be realized to a certain extent.
Main circuit our medium
frequency heating machine:
As said above, parallel
oscillating structure is applied in our SPZ medium frequency
heating systems. There are two kinds of combinations
usually used now according to the different
applications:
Combination 1：M.F. generator + compensating cap +
coil
This is the most popular
combination widely used now, for example, the M.F. forging
furnace and melting furnace. Machine of this kind is simple, low
cost, high efficiency.
In this combination, the
coil is large or long, usually 3 to *0 meters long copper tube is
needed to turn the coil. There is **0V high voltage directly
between the coil and is not safe. So to ensure the safety of the
operator, the coil must be insulated properly.
Combination 2：Generator +（compensating cap +
transformer） + coil
This combination is also used widely, for example, melting
furnace in vacuum and medium frequency quenching.
In this combination, Different
output current and voltage can achieved through the changing of
the ratio of the transformer to fit different applications.
In this combination, coil is
isolated from the main circuit, so the coil is safe and need low
insulation or no insulation.
Due to the adding of the
transformer, the size and the cost of the whole heating system
are raised, at the same time, transformer increases the energy
consumption. The lower the frequency, the more the
affection is.
The Control theory of
the Generator:
Inside our generators, IGBT module and our fourth generation
inverting control technology has been used, that is the soft and
dual control and inverting technology on the basis of parallel
oscillating circuit. In this technology, output power and
frequency can be controlled and adjusted separately, IGBT module
and soft switching control technology are used in the high
frequency switching circuit to control the output power. In
the inverting circuit, the IGBT and frequency tracing circuit is
applied to achieve high speed and accurate soft switching
control. The adoption of new technologies not only improves the
quality and reliability of the machine，but also solve the technology
problem on large power induction heating machine and makes it
possible to work **0% duty cycle.
