Taybetmendiyên firna frekansa navîn a rêzê:

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. The series intermediate frequency furnace has always had the characteristics of high power factor operation, and the power factor is higher than 0.95.

3. Di firna frekansa navîn ya rêzê de ahengên 5-emîn û 7-an tune

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. Pergala kontrolkirina hêza frekansa navîn ya rêzika firna frekansa navîn bi tevahî yekgirtî û dîjîtal e

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%.

Feydeyên rezonansa rêzê ya firna frekansa navîn a rêzê xwedan taybetmendiyên destpêkek baş, û faktora hêzê ne. Di rewşa barkirina tevahî û bargiraniya giran de, ew dikare bi kêfa xwe dest pê bike, û rêjeya serkeftina destpêkê digihîje 100%.

6. Di her rewşê de, veguherînerê hêza frekansa navîn a firna frekansa navîn a rêzê dikare bigihîje operasyona barkirina tevahî

Firinên frekansa navîn ên rêzê veguherînerek hêza frekansa navîn û çerxek rastkerek dualî, ango kabîneyek rastker parve dikin. Di her rewşê de, veguherînerê hêza frekansa navîn dikare bigihîje operasyona barkirina tevahî, bi vî rengî kapasîteya veguherîner kêm bike û du firneyên kevneşopî bi karanîna du veguherîner û du kabîneya qedandinê biguhezîne.

7. Firina frekansa navîn a rêzê bi pergalek çavdêrî û parastinê ya bêkêmasî ve tê stend

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.
