Overband Magnet iron remover fuse is always burned how to solve

The circuit problem in the use of the Overband Magnet iron remover is the main source of its fault. Many users have repeatedly burned the fuse when using the Overband Magnet iron remover, but can not find an effective solution. Today, the electromagnetic separator is suspended. The troubleshooting method for the problem of burning is explained to everyone:
1. Check the power supply line of the Overband Magnet separator to measure whether the voltage is normal;
2. Check whether the replaced fuse is consistent with the fuse type of the Overband Magnet separator manual;
3. After the new fuse is connected, measure the resistance of the suspension electromagnetic separator coil by power failure, or measure the coil current through the clamp ammeter when the power is on. Compare the rated resistance or current on the manual, if the resistance is small or current. If it is too large, it should be caused by overheating of the suction coil and causing a short circuit between the turns. It is necessary to re-wrap the coil. After the repair, it is necessary to check whether the ventilation cooling of the Overband Magnet separator coil is normal, and whether there are objects blocking the cooling around.
4. If the resistance and current of the coil are the same as those indicated on the manual, consider increasing the fuse. However, this operation is risky and is not recommended.
5. It is impossible to eliminate the need to contact the supplier who hangs the Overband Magnet iron remover in time for maintenance.
