Fitur tungku frekuensi menengah seri:

1. The power of the series intermediate frequency furnace can be adjusted and distributed arbitrarily

Tungku frekuensi menengah seri dapat mewujudkan penyesuaian dan distribusi daya keluaran yang sewenang-wenang hanya dengan memutar tombol potensiometer daya pada panel catu daya inverter. Dua tungku dapat dilebur pada saat yang sama atau satu tungku tubuh dapat dilebur dan tubuh tungku lainnya dapat tetap hangat. Dimungkinkan juga untuk melebur satu tungku frekuensi menengah dan menghentikan yang lain untuk siaga. Untuk peleburan tunggal, penggunaannya sangat fleksibel. Pengoperasiannya sangat nyaman, dan dapat tetap hangat, memanas, dan marah pada suhu yang akurat, dan memaksimalkan keluaran air untuk memenuhi pengecoran bobot benda kerja yang berbeda.

2. Tungku frekuensi menengah seri selalu memiliki karakteristik operasi faktor daya tinggi, dan faktor daya lebih tinggi dari 0.95.

3. The series intermediate frequency furnace does not contain the 5th and 7th harmonics

Tungku frekuensi menengah satu-ke-dua dalam tungku frekuensi menengah seri mengadopsi rangkaian penyearah yang dikendalikan sepenuhnya oleh thyristor 12-pulsa. Pengaturan tegangan dan pengaturan daya berbeda dari catu daya frekuensi menengah dari tungku frekuensi menengah dua tungku satu-listrik. Ini adalah keuntungan untuk melindungi inverter dan memotong daya dengan cepat. Catu daya frekuensi menengah thyristor 12-pulsa tidak mengandung komponen harmonik ke-5 dan ke-7. Menurut analisis harmonik, efek harmonik dari catu daya yang diperbaiki 12-pulsa jauh lebih kecil daripada catu daya frekuensi menengah KGPS biasa.

4. Sistem kontrol daya frekuensi menengah dari tungku frekuensi menengah seri terintegrasi 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. Tingkat keberhasilan memulai tungku frekuensi menengah seri mencapai 100%.

The advantages of series resonance of series intermediate frequency furnace have good starting characteristics, and power factor. In full load and heavy load state, it can start at will, and the starting success rate reaches 100%.

6. Bagaimanapun, transformator daya frekuensi menengah dari tungku frekuensi menengah seri dapat 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.
