Electromagnetic heater is now the most widely popular, it is quite possible energy saving heating equipment, high-power electromagnetic heater is then on how we ought to very good use of it, we took 80KW electromagnetic heating controller, for example for a He said. Power electromagnetic heater movement inside a large current of the main circuit will be fever, so that the main way to fight back on the screws due to hot and cold and loose, perhaps, for example, capacitors, rectifier bridge modules, and coil terminal , assuming there is not good will heat conductivity loose, there will be serious and even burned tinder appearance, so the movement should also check with something loose screw is not punctual. Electromagnetic heating load coil also through high-frequency, usually will heat more serious, usually pay attention to query coil is not damaged, particularly spent more than a year, and have been the demolition of the coil, there may have been aging, simple twist off part of the wire, so that the inductance vary but upside movement is not working in the best working condition, the movement loss of a large number also reduced the use of life short. So when loading coil also keep checking, such as the need to replace aging. You can check the movement of the panel operating parameters, usually you can check the current and the operating frequency is not suitable, the movement is not the long-term temperature at high temperatures, assuming operating parameters deviate from the best working point, the movement loss is large, the use of life Number of course shortened. So check the movement of the operating parameters can grasp the movement of work from time to time, need to check if any abnormal reason, troubleshooting.
