False load and protective measures for repair of electromagnetic furnace


It can be to repair a switching power supply of the electromagnetic oven is not energized at both ends of the insurance after 100W lighting (remove insurance), repair IGBT tube breakdown can remove resonant line after hours at the two ends of the resonant capacitor and winter sun heater heating pipe 800W or 1000W, of course, IGBT and insurance has been replaced with a new, the voltage is normal, such as 18-20v 5V. In the electromagnetic furnace repair after especially burst insurance after repair, do not take 10A-12A insurance, and insurance 1a, connect the coil not to put the pot is energized, listen to the sound, whether alarm or display fault code E0 and E1 (i.e. no pot). The power line single card clamp meter to see whether there is a 0-0.1A jump back and forth. After completion of each electromagnetic oven after watching the current clamp table, fine-tuning power detection can be adjustable resistor, current than the nominal value of small 1a, reduce the risk but has little effect on the user (slower Bale)
After replacement of high power tube to wiring coil is the most simple method, but the coil panel wiring column connected to a incandescent lamp and re energized, even if the circuit and fault, it will not burn tube, if the incandescent lamp does not light or just flashing, indicating circuit is basically no problem the, can be connected to the coil energized test machine, if the incandescent lamp has been lit, circuit and problems.
Before changing the tube with a light emitting diode is connected to the base and the end of the tube. (light emitting diode plus 100 ohm resistor) even online disk boot check light emitting diode is with the alarm sound rules of flash can view check to push pipe is normal.
The electric light of the 100~200W is intended to measure the working potential of each point, in particular, 339 of the feet. If not normal, the light bulb will be very bright, but immediately power. It is the same thing that the string is connected to the fuse loop and removed the fuse. So, the end of the lamp terminal or the end of the fuse is the same as the end effect is the same.
