Makala ya mfululizo wa tanuru ya mzunguko wa kati:

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

The series intermediate frequency furnace can realize the arbitrary adjustment and distribution of output power only by rotating the power potentiometer button on the inverter power supply panel. Two furnaces can be smelted at the same time or one furnace body can be smelted and the other furnace body can be kept warm. It is also possible to smelt one intermediate frequency furnace and stop the other for standby. For single smelting, the use is very flexible. The operation is very convenient, and it can keep warm, heat up, and temper at the accurate temperature, and maximize the water output to meet the casting of different workpiece weights.

2. Mfululizo wa tanuru ya mzunguko wa kati daima imekuwa na sifa za uendeshaji wa kipengele cha juu cha nguvu, na kipengele cha nguvu ni cha juu kuliko 0.95.

3. Tanuru ya mzunguko wa kati ya mfululizo haina harmonics ya 5 na 7

Tanuru ya masafa ya kati-moja-hadi-mbili katika mfululizo wa tanuru ya masafa ya kati inachukua mzunguko wa kirekebishaji kinachodhibitiwa kikamilifu na 12-pulse thyristor. Udhibiti wa voltage na udhibiti wa nguvu ni tofauti na ugavi wa umeme wa kati-frequency ya tanuru moja ya umeme ya tanuru ya kati-frequency. Ni faida yake kulinda inverter na kukata nguvu haraka. Ugavi wa umeme wa mzunguko wa kati wa 12-pulse thyristor hauna vipengele vya 5 na 7 vya harmonic. Kulingana na uchanganuzi wa sauti, athari ya usawa ya usambazaji wa umeme uliorekebishwa wa mipigo 12 ni ndogo sana kuliko ile ya usambazaji wa umeme wa masafa ya kati ya kawaida ya KGPS.

4. Mfumo wa udhibiti wa nguvu wa mzunguko wa kati wa mfululizo wa tanuru ya mzunguko wa kati umeunganishwa kikamilifu na 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%.

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. Kwa hali yoyote, kibadilishaji cha nguvu cha masafa ya kati cha safu ya tanuru ya masafa ya kati kinaweza kufikia operesheni kamili ya mzigo.

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

Bodi ya udhibiti wa tanuru ya mzunguko wa kati ya mfululizo ina kazi ya kujitambulisha kwa mlolongo wa awamu. Joto la kazi la inverter ya mfululizo na capacitor ya chujio inafuatiliwa na meza ya kubadili joto. Mara tu halijoto ya maji ya kupoa inapozidi thamani iliyowekwa au kuna hitilafu ya maji, kengele itatolewa na mzunguko wa kurekebisha mara mbili wa 12-pulse itakatwa. . Pembejeo ya maji ya baridi ya usambazaji wa umeme wa mzunguko wa kati hudhibitiwa na relay ya shinikizo la maji, na pato la maji ya baridi hufuatiliwa na mita ya kubadili joto ili kufuatilia upungufu. Juu ya halijoto itatoa kengele na kukata mzunguko wa kurekebisha mipigo 12. Baraza la mawaziri la udhibiti lina vifaa vya voltmeter ya pato, mita ya nguvu ya pato, mita ya mzunguko wa kufanya kazi, ammeter ya pembejeo, voltmeter ya pembejeo, voltmeter ya DC, ammeter ya DC, na bodi ya udhibiti wa 12-pulse ina vifaa vya kuonyesha hasara ya awamu na maonyesho ya kazi ya inverter. Tanuri mbili za masafa ya kati zinaweza kuonyesha voltage ya masafa ya kati, nguvu na masafa ya uendeshaji mtawalia. Kivunja mzunguko kimewekwa kwenye baraza la mawaziri la udhibiti wa kurekebisha mipigo 12, ambayo ni sehemu ya kukatiwa inayoonekana kwa swichi ya kutengwa ya umeme inayoingia ya masafa ya kati na swichi ya kisu, yenye ulinzi wa mzunguko mfupi, ulinzi wa safari ya ardhini na ulinzi wa upotevu wa awamu, fusi, nk Sehemu za awali za umeme zimeundwa kwa busara, na kutokwa ni nadhifu. Matengenezo na uingizwaji wa sehemu ni rahisi na haraka. Vipengele vyote vikuu vya kupokanzwa na baa za shaba vina vifaa vya baridi vya maji kulingana na mahitaji.
