China medium frequency induction copper
melting furnace with energy saving advantage
Unique new type patent for thyristor and capacitor uniform current
Currently, thyristor serial-connected electric furnace is most widely applied in casting industry and it is also one of the lowest power consumption devices with a power factor of over 0.95. Compared with parallel-connected thyristor types , its power efficiency is much higher and power can be saved 20% higher than them.
Thyristor serial-connected equipment is durable and it has no special requirements for working environment, it can be applied under various environments with high safety performance, and it is also provided with various protective measures such as water pressure detection and temperature detection for water pipeline.
Fast smelting speed and low power consumption are also the most unique advantage of thyristor serial-connected smelting system.
4. Low failure rate
Failure rate is very low and malfunctions hardly occurs within five years, even if any minor problems occur, maintenance is very simple and convenient, so this is one of the reasons why it is widely praised in this industry.
Technical advantages:
Mature technology, no high harmonics, maximum power factor, power factor can be over 95%, power compensation devices and harmonic elimination device are not needed any more.
