How many square cables do you need for a 750kw intermediate frequency melting furnace ?
0.75kw intermediate frequency melting furnace , secondary power supply with 2*yjv240 copper wire cable, running at full load. The transformer should be 1000KVA. Use at least 4*300. Or 100*10 box bus.
Medium frequency melting furnace : It is a power supply device that converts power frequency 50HZ alternating current into intermediate frequency (300HZ to 1000HZ). The three-phase power frequency alternating current is rectified and turned into direct current, and then the direct current is converted into adjustable intermediate frequency current. The intermediate frequency alternating current flowing through the capacitor and the induction coil generates a high-density magnetic line in the induction coil, and cuts the metal material contained in the induction coil to generate a large eddy current in the metal material.
Medium frequency melting furnace features
A The melting speed is fast, the power saving effect is good, the burning loss is small, and the energy consumption is low.
B Self-mixing function, melting temperature and uniform metal composition.
C Electric heating work environment is good.
D start performance is good, empty furnace, full furnace can reach 100% start
How high is the transformer voltage? If it is 380 volts, then use three copper wires of BV240 as one. Each can pass 600 amps of current, and three are one thousand eight hundred amps. You can drive the furnace power to one thousand without problems. However, there is a defect in the combination of three, that is, due to the action of the magnetic field, the three parallel wires have a bias current phenomenon, but it does not affect the use. It is enough to use a copper row to reach a section area of 750 square millimeters. Your stove is said to be 750kw, it may be necessary to increase the power when it is used. If you want to melt it fast, the 720 copper row has a margin, no problem.
