Energy-saving! Air cooling power supply for billet induction heating furnace
Specializes in producing air cooling energy-saving billet induction heating furnace, Forever power supply cabinet can save 30% power than other power supply. Having more than 14 years experience, Forever has designed more than 10,000 sets of billet induction heater for users at home and abroad.
The advantages of Forever air cooling billet induction heating furnace
1.Using all-digital constant power IGBT series air-cooled IF power supply, the core technology is the intelligent microcomputer IF control board. Standard series plug-in circuit boards makes maintenance extremely convenient. The control part is mainly composed of regulator, phase-shift controller, protection circuit, start-up circuit, frequency tracking, inverter pulse, pulse amplification and power drive.
2.Power input section contains a set of automatic tracking rectifier device, the signal tracking and sampling parts are from the inductor and DC filter device. The input control signal is designed to standard voltage and current signals control mode. Using double closed-loop PI regulator which take voltage regulation for the outside loop and current regulation as inside loop.The output current fluctuations is small. Constant power output can ensure the maximum efficiency of the furnace while operation.
3. Rectification control circuit and all digital trigger minimize the non-characteristic harmonics, reducing grid pollution.
4. Power inverter part uses voltage feedback mode, and the power regulation uses voltage regulator, which is adjust through the voltage of 0 ~ 10V to power. After comparing the output power and setting power, the result will be fed back to power automatic control system. It has a strong ability of anti-interference.
5.Make full use of the intelligent function of the single chip computer, and make up the protective measures with complete functions.
6.It has perfect multi-stage protection: cooling water pressure loss; three-phase loss, undervoltage; overcurrent protection; overvoltage protection;
7.Intelligent program control, such as operation interlocking, self excitation / self excitation switching, automatic / manual switching, heating start / stop detection, main road electrical detection, failure reset state detection, etc.
8.These functional states are displayed by digital display, so that the operation management is simple and clear.
9. The start-up mode is advanced sweep frequency zero voltage start, reliable start-up (no matter no load or full load), so the operator can achieve 100% successful start without starting voltage and frequency.
10.The control circuit has the function of soft start and soft stop to avoid too rise in current and voltage in the process of start/stop machine, which will cause overvoltage and overcurrent.
11.Cabinet structure enables the thyristor power to work normally in a highly polluted environment. It makes debug or maintenance become more convenient.
12. The remote control of the control room can be realized through the local control / remote control switch and the interface.
13. The power supply cabinet has the function of automatic adaption when replacing different induction heaters. No need to adjust the generator parameters.
