Reasons why the electromagnetic switch coil of diesel generator set is burned out

As we all know, long-term use of diesel generator sets will cause some parts to wear out, and then they are not inspected and maintained during normal use. Under such cumulative conditions, the diesel generator set cannot start, and the electromagnetic switch of the generator The coil is burned out. Next, Haixing Power will introduce to you the reasons why the electromagnetic switch coil burns out?

The diesel generator set cannot start, and then the electromagnetic switch burns out, which mostly occurs in the holding coil. The reasons are as follows:

1. The holding coil of the diesel generator set is relatively thin, and current flows through it during the entire starting process of the diesel generator set, and the working time is long; the suction coil wire diameter is relatively thick, and the working time is short, and it is only used at the end of the main circuit before it is turned on. An electric current passes through it in an instant.

2. When the diesel generator set is in poor technical condition, the starting time is too long, causing the holding coil to overheat and burn out.

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

4. The reason why the suction coil of the electromagnetic switch of the diesel generator set is burned out usually occurs when the guide plate and the fixed contact cannot connect the main circuit and the replaced fuse is too large.

It can be seen that in order to avoid the burnout of the electromagnetic switch of the diesel generator set, we usually need to check and maintain it frequently when using the diesel generator set, so that we can discover the problem in time, solve the problem in time, and avoid causing greater loss.
