How to solve the problem of excessive voltage for Diesel Generator

How to solve the problem of excessive voltage for Diesel Generator

1. The engine speed of the diesel engine unit is too high.

Treatment method: reduce the turbine guide opening and reduce the speed.

2. The air gap of the shunt reactor is too large.

Treatment method: change the thickness of the reactor core gasket and adjust the air gap.

3. The magnetic field varistor is short-circuited; the voltage regulation fails.

Treatment method: Find the short circuit point and eliminate it.

4, Chengdu Generator accident speed.

Treatment method: Emergency shutdown for accident handling.

5. Check if the load carried by the unit is a capacitive load (power factor ahead).
