How to solve the low voltage phenomenon of silent gas generator?

huaquan_liuming发布

Recently, Xiaobian heard that everyone had such a headache. The phenomenon of low voltage appears in silent gas generator set. How to solve this problem? Silent gas generator manufacturers have know-how. It is mainly analyzed from the following points:

1. Check whether it is caused by the uneven surface of the commutator

Silent gas generator set is due to the brush contact surface is too small, poor contact caused by the low voltage. At this time, you need to check whether it is caused by the surface of the commutator. If so, you can go at low speed. Polish the commutator surface with emery cloth. Or adjust the spring pressure.

2. Check whether the diesel engine speed is too low

Too low voltage has appeared in the generator set. The technician checked that the speed of the original power diesel engine of the generator set was too low. At this time, just adjust the speed of prime mover to the rated value.

3. Check whether the resistance of excitation circuit is too high

If the diesel generator set is in use. Because the resistance of excitation circuit is too high, the unit voltage is too low. At this time, we need to reduce the resistance of the field rheostat to increase the excitation current.

4. Whether the exciter brush is at the neutral position.

If your unit is because the exciter brush is not in the neutral position. You need to set the brush to the correct position. Or replace the brush to solve the problem of low voltage.

5. There is short circuit or ground fault in stator winding or excitation winding.

Generator set is due to short circuit or ground fault in stator winding or excitation winding. You need to check the fault and clear it in time.

The above is the knowledge that Xiaobian explained to you. HuaQuan power has a rigorous working attitude. Good working skills. Will ensure that the task is completed accurately and efficiently.
