Intermediate frequency furnace power and dc current technology, an intermediate frequency furnace with dc voltage without current answer: impossible without dc current, unless the current meter is broken, there was something wrong with furthermore voltage divider, reactor have voice: there must be an electric current passes through. To replace the SCR. Intermediate frequency furnace when up to 1300 v dc current flow through a circuit breaker is going on intermediate frequency furnace power and dc current answer: according to your description, dc voltage 500 v, intermediate frequency voltage 650 v, you this equipment should belong to medium frequency power supply of 380 v into line. As for you said the current up to 1300 v ( The actual should be 1300 a) Jump circuit breaker, the possible problems in the circuit breaker itself, attention should be paid to the same current level of circuit breaker, factory setting current may be different, according to the current 1300 a your device. What is the difference between the electric arc furnace and intermediate frequency furnace answer: 1, the electric arc furnace, big volume are generally not more than 3 tons, have a certain scale of the enterprise to use the electric arc furnace, smelting steel is more pure. Intermediate frequency furnace: relative electric arc furnace steelmaking cost lower, suitable for small and medium enterprises, refining the steel material, high carbon steel coming out is not so pure. 2, electric arc furnace with electric power frequency; Intermediate frequency electric furnace used. Low intermediate frequency furnace to midway when direct current (dc) rheological what reason be? Answer: the failure analysis and treatment: the failure phenomenon does not belong to the intermediate frequency power supply failure, but because of the load impedance is too low to cause, should readjust to load impedance. 1) In the circuit of pressure load, due to the damage to dismantle series compensation capacitor, not replace, or blindly pursue high power and increase compensation capacitor unchecked, load compensation amount. Intermediate frequency furnace induced current is about? A: 075 ~ 1 tons of intermediate frequency furnace, power in the 600 kw to 750 kw, if the line voltage is 380 v, the dc current is 800 ~ 1000 in you. How to calculate the ratio of intermediate frequency furnace of frequency voltage and dc voltage, and power of intermediate frequency furnace and direct current answer: the ratio of intermediate frequency furnace of frequency voltage and dc voltage is 1. Three times. Before the adjustment Angle of potentiometer. Intermediate frequency furnace power factor in determining a: although the power factor is lower, also be ok. Because we are now the metering electricity meter, are active power meter, the actual charge is according to the active power of electric power. Low power factor, just reactive power line loss will bring some active power consumption. Or is equal to the capacity on your lines. For example, my factory is 630. How to dc current in medium frequency furnace control board raised? Answer: generally on the right side of the circuit board and the corresponding two small fine-tuning potentiometer for current W1 W2 for voltage. After the medium frequency furnace melting materials, intermediate frequency voltage, dc voltage power and direct current answer: why the decline in intermediate frequency furnace is constant power furnace, furnace charge after the Curie point the melting temperature, hysteresis effect disappeared, temperature resistance increases, the eddy current reduced, induction coil, and the mutual inductance are also decreases, and the total impedance load increases, the dc current must be reduced, that's right. But if constant power furnace, intermediate frequency voltage should not be reduced, because have the effect of the main resistance regulator. Intermediate frequency electric furnace and intermediate frequency voltage dc voltage is how many answer: should be slot way matching unreasonable, frequency tracking does not work, the work frequency deviation slot way too far, namely frequency deviation resonance point too far, cause too much electricity. Intermediate frequency furnace power and dc current technical data of intermediate frequency furnace ac change dc to ac voltage is? A: yes. The working principle of intermediate frequency power supply for: the three-phase bridge type all control the ac rectifier for dc rectifier circuit, after the flat wave reactor, became a constant dc current source, to the single phase inverter bridge, the dc current inverter with a certain frequency ( General is 1000 - 8000Hz) The single-phase medium frequency current. Each master, could you tell me which one know power of intermediate frequency furnace size and the active power filter medium frequency furnace and direct current answer: measure. Choose active filter and harmonic relationship, which you can refer to the intermediate frequency furnace power about harmonic content size, manufacturers can recommend model according to the size of the harmonic content; Or looking for an experienced manufacturer directly, will directly have recommended. Are passive filter series circuit, the power requirement can certainly and intermediate frequency furnace power is consistent. Intermediate frequency furnace dc current is start to the 100 a dc voltage is not start because of intermediate frequency furnace power and dc current answer: look at the inverter or capacitor is short circuit. Intermediate frequency furnace current can't more than how many degrees? Intermediate frequency furnace power and dc current answer: medium frequency furnace, most current should not exceed 300 degrees. Intermediate frequency furnace of rectifier and inverter current change a: alternating current (ac) through the rectifier into direct current, dc energy is stored, direct current through the inverter into the required frequency of the alternating current. Medium frequency furnace has dc voltage no intermediate frequency voltage is what reason? Intermediate frequency furnace power and dc current answer: failure analysis and treatment: the failure phenomenon does not belong to the intermediate frequency power supply failure, but because of the load impedance is too low to cause, should readjust to load impedance. 1) In the circuit of pressure load, due to the damage to dismantle series compensation capacitor, not replace, or blindly pursue high power and increase compensation capacitor unchecked, load compensation amount.
