Ciri-ciri relau frekuensi pertengahan siri
Ciri-ciri relau frekuensi pertengahan siri:
1. The power of the series intermediate frequency furnace can be adjusted and distributed arbitrarily
Relau frekuensi perantaraan siri boleh merealisasikan pelarasan sewenang-wenangnya dan pengagihan kuasa output hanya dengan memutarkan butang potensiometer kuasa pada panel bekalan kuasa penyongsang. Dua relau boleh dilebur pada masa yang sama atau satu badan relau boleh dilebur dan badan relau yang lain boleh disimpan hangat. Ia juga mungkin untuk mencium satu relau frekuensi perantaraan dan menghentikan yang lain untuk siap sedia. Untuk peleburan tunggal, penggunaannya sangat fleksibel. Operasi ini sangat mudah, dan ia boleh memanaskan badan, memanaskan dan marah pada suhu yang tepat, dan memaksimumkan keluaran air untuk memenuhi tuangan berat bahan kerja yang berbeza.
2. Relau frekuensi perantaraan siri sentiasa mempunyai ciri-ciri operasi faktor kuasa tinggi, dan faktor kuasa lebih tinggi daripada 0.95.
3. The series intermediate frequency furnace does not contain the 5th and 7th harmonics
The one-to-two intermediate-frequency furnace in the series intermediate-frequency furnace adopts a 12-pulse thyristor fully-controlled rectifier circuit. The voltage regulation and power regulation are different from the intermediate-frequency power supply of the one-electric two-furnace intermediate-frequency furnace. It is its advantage to protect the inverter and cut off the power quickly. The 12-pulse thyristor intermediate frequency power supply does not contain the 5th and 7th harmonic components. According to the harmonic analysis, the harmonic effect of the 12-pulse rectified power supply is much smaller than that of the ordinary KGPS intermediate frequency power supply.
4. Sistem kawalan kuasa frekuensi perantaraan bagi relau frekuensi perantaraan siri bersepadu sepenuhnya dan digital
The control system of series intermediate frequency furnace is fully digital, without relay control, dynamic voltage equalization, with phase loss, overvoltage, overcurrent, low water pressure and human error protection, current limiting, voltage limiting, balance, stable function, frequency sweep start Good performance. The structure is simple, energy-saving and power-saving, the control board is easy to debug, and there are only 5 potentiometers for adjustment. Simple operation and maintenance.
5. The success rate of starting the series intermediate frequency furnace reaches 100%.
Kelebihan resonans siri relau frekuensi pertengahan siri mempunyai ciri permulaan yang baik, dan faktor kuasa. Dalam keadaan beban penuh dan beban berat, ia boleh bermula sesuka hati, dan kadar kejayaan permulaan mencapai 100%.
6. Walau apa pun, pengubah kuasa frekuensi perantaraan bagi relau frekuensi perantaraan siri boleh mencapai operasi beban penuh
Series intermediate frequency furnaces share an intermediate frequency power transformer and a double rectifier circuit, that is, a rectifier cabinet. In any case, the intermediate frequency power transformer can reach full load operation, thereby reducing the capacity of the transformer and changing the conventional two furnaces using two transformers and two finishing cabinet.
7. The series intermediate frequency furnace is equipped with a complete monitoring and protection system
The control board of the series intermediate frequency furnace has the function of phase sequence self-identification. The working temperature of the series inverter and filter capacitor is monitored by a temperature switch table. Once the cooling water temperature exceeds the set value or there is a water failure, an alarm will be issued and the 12-pulse double rectifier circuit will be cut off. . The cooling water input of the intermediate frequency power supply is controlled by a water pressure relay, and the cooling water output is monitored by a temperature switch meter to monitor the undervoltage. Over temperature will issue an alarm and cut off the 12-pulse double rectifier circuit. The control cabinet is equipped with output voltmeter, output power meter, working frequency meter, input ammeter, input voltmeter, DC voltmeter, DC ammeter, and the 12-pulse control board is equipped with phase loss display and inverter work display. Two intermediate frequency furnaces can display intermediate frequency voltage, power and operating frequency respectively. A circuit breaker is installed in the 12-pulse double rectifier control cabinet, which is a visible disconnection point for the intermediate frequency power supply incoming line isolation switch and knife switch, with short circuit protection, ground trip protection and phase loss protection, fuses, etc. The original electrical parts are designed reasonably, and the discharge is neat. The maintenance and replacement of parts are convenient and fast. All the major heating elements and copper bars are equipped with reasonable water cooling according to the needs.
