Tips: Coil overheating or burning, how to solve?
Possible Causes:
- The power supply voltage is too high or too low.
- Line technical parameters (such as rated voltage, frequency, load factor and applicable working system, etc.) do not match the actual use.
- Operating frequency is too high.
- Insulation damage due to poor coil manufacturing or mechanical damage.
- The moving part is stuck.
- The AC core is uneven or the magnetic air gap is too large.
- AC contactor derives the double coil of DC operation, because the normally closed interlocking contact welding does not release, and the coil is overheated.
Processing method:
- Adjust the power supply voltage.
- Exchange coils or contactors.
- Select other suitable contactors.
- Replace the coil to remove the obstacle that causes mechanical damage to the coil.
- Specially designed coils.
- Eliminate jamming.
- Clear the pole face or change the core.
- Adjust the interlocking contact parameters and replace the burnt coil.
