1. Energy saving power saving
After years of comparison discovery, IGBT series resonance technology is 40% to 60% compared with the electronic pipe equipment, 20% to 30%, which is 20% to 30%, which is 10% -15% compared to the parallel IGBT equipment, and its energy saving is saved. Advantages meet the guidance of the current national energy-saving and emission reduction policy. The inductance and coil in series resonant main circuits is a series structure, and parallel resonance is inductively and coils as parallel structures. According to the derivation, the loss of the parallel resonant circuit is about 25 times that of the series resonant loop loss. At present, the national grid uses high voltage transmission mode during transmission because there is a large loss on low voltage transmission lines. The series resonance technology is similar to the principle of high voltage transmission, and the power delivery method of high voltage, small current, low loss is employed. The transmission of parallel resonance technology is equivalent to low voltage transmission.
2. High reliability
The inverter needs to currently perform current and voltage commutation in the work, convert the DC power to a high frequency AC power source. There is a phase difference between the current commutation and the voltage commutation of the ordinary inverter, the power factor is low, and the reactive power loss is large. By using the fourth-generation ZCT technology, Komantry makes the phase difference between the current commutation and the voltage commutation. The current voltage impact of the device is small, and there is a high power factor in the full power range, effectively Save energy and greatly improve equipment stability.
3. High control accuracy
Power control technology adopted by ordinary induction heating technology - thyristor rectification technology, the disadvantage of this technology is that the response is slow, and the current is easily distorted during deep control, and the network side power factor is low, and the grid is contaminated. Kongchuang adopts real full-solid IGBT transfer and variable flow control technology, using unique 1GBT soft switch high frequency chopping and amorphous filtering, and high-speed precision soft switch IGBT inverter control, realization 0.1 ~ 500kHz, 8-1000KW product application. It adopts Kibokian dual-regulatory converting control technology, the power and frequency conversion independent regulation, replacing the traditional thyristor transfer technology with high-frequency chopping techniques, realizing the control of microsecond levels, greatly achieving the rapid adjustment and stability of power output, The output ripple is very small, and the oscillation current is stable. When the grid voltage fluctuates, it is ensured that the temperature stability of the workpiece in which the workpiece in which heating is induced.
4. Load Matching
Using a resonant dielectric load matching technique, the induction heating power supply can output rated power when heating different workpieces, and achieves the purpose of rapid heating. Since the series resilience matches the transformer input voltage high, the load is more than the load matching range. Take 500kW as an example, use the same match matching transformer, which can be loaded with a single-turns inducer to reach 1200mm in 920-, and the rated power can be output in normal load.
For fixed-point heating fields, the magnetic permeability of the workpiece is different, and the load corresponding to the power supply is also different. The output power of the conventional induction heating power supply varies with the temperature of the workpiece, and the maximum power cannot be always output, the heating efficiency is low. Using the adjustable multi-ratio transformer, it can greatly improve the matching load range of the power supply, and the power supply can maintain large output power in different temperature changes, and realize rapid heating.
5. Combined design
The frequency automatic tracking circuit is used to start the success rate of 100%. Billy By modular combination of induction heating equipment, frequency, and load, becomes a single frequency, one dual frequency, one drag two single frequency, one-double frequency, etc., more different combined products, greater limit Place the equipment efficiency. The Komantui product uses a complete set of equipment modular design, such as induction heating power supply, CNC machine tool, robot, closed water cooling equipment, etc. The customer uses induction heating equipment to extend the field of sensing heating applications, saving customer financial costs and human costs. Serial resonance techniques have been widely used in heat transfer, brazing, smelting and other fields, and are also applicable to many enterprises in the induction heat treatment process. Since 1GBT series resonance techniques exhibit many advantages in applications, series resonance techniques will become the development trend of induced heat treatment applications. Advanced 1GBT series technology also has other advantages, such as the full control function, rich exterior interface, no pollution, and small footprint. Kobe Chuang 1GBT full solid state power supply has gradually matured well. Low-band replacement brake power supply, high-frequency segment replace electronic tube high frequency power supply is an inevitable trend of science and technology development. At present, my country has proposed to achieve energy saving and emission reduction, and the construction of modern enterprises, hot processing areas and even traditional military units. After the productivity is upgraded, they have gradually placed old equipment, using new GBT power supplies as the preferred induction heating equipment to achieve energy saving The purpose of emission reduction. Komang GBT induction heating equipment has been widely used in automotive parts, aerospace, aviation, new energy and other fields.
