Features of series intermediate frequency furnace:

1. The power of the series mellemfrekvensovn 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. 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. The intermediate frequency power control system of the series intermediate frequency furnace is fully integrated and digital

Kontrolsystemet for seriemellemfrekvensovne er fuldt digitalt, uden relæstyring, dynamisk spændingsudligning, med fasetab, overspænding, overstrøm, lavt vandtryk og menneskelig fejlbeskyttelse, strømbegrænsning, spændingsbegrænsning, balance, stabil funktion, frekvenssweep-start God præstation. Strukturen er enkel, energibesparende og strømbesparende, styrekortet er let at fejlsøge, og der er kun 5 potentiometre til justering. Enkel betjening og vedligeholdelse.

5. Succesraten for at starte serie-mellemfrekvensovnen når 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. In any case, the intermediate frequency power transformer of the series intermediate frequency furnace can reach full load operation

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. Seriens mellemfrekvensovn er udstyret med et komplet overvågnings- og beskyttelsessystem

Kontrolkortet i seriemellemfrekvensovnen har funktionen af ​​fasesekvens-selvidentifikation. Arbejdstemperaturen for serieinverteren og filterkondensatoren overvåges af en temperaturafbrydertabel. Når kølevandstemperaturen overstiger den indstillede værdi, eller der er et vandsvigt, udsendes en alarm, og 12-puls dobbeltensretterkredsløbet afbrydes. . Kølevandstilførslen af ​​mellemfrekvensstrømforsyningen styres af et vandtryksrelæ, og kølevandsoutputtet overvåges af en temperaturafbrydermåler for at overvåge underspændingen. Overtemperatur vil afgive en alarm og afbryde det 12-puls dobbelt ensretterkredsløb. Styreskabet er udstyret med udgangsvoltmeter, udgangseffektmåler, arbejdsfrekvensmåler, inputamperemeter, inputvoltmeter, DC voltmeter, DC amperemeter, og 12-puls styrekortet er udstyret med fasetabsdisplay og inverter arbejdsdisplay. To mellemfrekvensovne kan vise henholdsvis mellemfrekvensspænding, effekt og driftsfrekvens. Der er installeret en afbryder i det 12-puls dobbelt ensretter styreskab, som er et synligt afbrydelsespunkt for mellemfrekvensstrømforsyningens indgående ledningsafbryder og knivafbryder, med kortslutningsbeskyttelse, jordudløsningsbeskyttelse og fasetabsbeskyttelse, sikringer, osv. De originale elektriske dele er designet fornuftigt, og afladningen er pæn. Vedligeholdelse og udskiftning af dele er praktisk og hurtig. Alle de store varmeelementer og kobberstænger er udstyret med rimelig vandkøling efter behov.
