Causes of the electromagnetic switch coil burnout of diesel generator set

As we all know, diesel generator sets will cause wear and tear in certain parts during long-term use, and then they will not be inspected and maintained during normal use. With this accumulation of time, the diesel generator set cannot be started and the generator electromagnetic switch coil is burned out. Next, Haixing Power will introduce to you what are the reasons for the burnout of the electromagnetic switch coil?

This causes the diesel generator set to fail to start, and then the electromagnetic switch is burned, which often occurs in the holding coil. The reasons are as follows:

1. The holding coil of the diesel generator set is relatively thin, and current passes through the entire starting process of the diesel generator set, which is long working time; the diameter of the pull-up coil is thicker and the working time is short, and the current passes through the moment before it is turned on at the end of the main circuit.

2. When the diesel generator set is in poor technical condition, the starting time is too long, which causes the retaining coil to overheat and burn.

3. After the diesel generator set is started, the preheating start switch knob cannot automatically return to the '0' position, or the start switch copper disc is bonded, causing the start generator to run continuously.

4. The reason why the pull-up coil of the electromagnetic switch of the diesel generator set is usually caused by the fact that the fuse replaced by the deflector and the fixed contact cannot be turned on and the fuse replaced is too large.

It can be seen that in order to avoid burning out the electromagnetic switch of the diesel generator set, we usually need to check and maintain frequently when using the diesel generator set, so that the problem can be discovered in a timely manner, and the problem can be solved in a timely manner, and greater losses can be avoided. If you have knowledge about generator sets and don’t know about them, you can consult Haixing Power’s technicians.
