How to repair the fault of water cooling cable of induction heating equipment
Induction heating equipment water-cooled cable is made of stranded copper wires with a diameter of Φ0.6–Ф0.8, a conductive carrier with sufficient current carrying capacity, and cable joints, anti-corrosion, high-quality rubber tube with good flame retardancy made.
The outer rubber tube of the water-cooled cable of the induction heating equipment adopts a pressure rubber tube with a pressure resistance of 5 kg, and the cooling water is passed through it. It is a part of the load circuit. It is subjected to tension and torsion during operation, and it tilts together with the intermediate frequency furnace body and twists and turns, so the time It is easy to break at the flexible connection after being long.
In the process of breaking the water-cooled cable of induction heating equipment, it is generally first to cut off most of it, and then quickly burn off the unbroken part during high-power operation. At this time, the intermediate frequency power supply will generate a high overvoltage. If the overvoltage protection is not Reliable, it will burn out the inverter thyristor. After the water cooling cable is disconnected, the intermediate frequency power supply cannot start to work. If you do not check the cause and start repeatedly, it is likely to burn out the intermediate frequency voltage transformer. When checking the fault, first disconnect the water-cooled cable from the output copper bar of the electric heating capacitor, and measure the resistance value of the cable with a multimeter electric block (200Ω block). When measuring with a multimeter, the furnace body should be turned over to the dumping position, so that the water-cooled cable will fall off, so that the broken part can be completely separated, so as to correctly judge whether the core is broken or not.
