The cause of high voltage alarm failure in 400kw diesel generator set

High voltage alarm failure of 400kw diesel generator set is one of the most common problems encountered by users. We all know that a high-quality diesel generator set can bring stable output power. Too high or too low voltage may affect the diesel generator set. Use, when the 400kw diesel generator set has high voltage and alarms, it should be checked and adjusted from the following four possible reasons.

 

       Diesel generator set is a large-scale precision mechanical equipment, most users are not experts in this field, so it is inevitable to encounter various problems in the process of use, such as high voltage alarm failure of 400kw diesel generator set is one of the user comparison Frequently encountered problems, then this article, generator manufacturer Dingbo Power, will specifically talk about the causes and solutions of high-voltage alarm failures in 400kw diesel generator sets.

 

       We all know that a high-quality diesel generator set can bring stable output power. Too high or too low voltage may affect the use of the diesel generator set. When the 400kw diesel generator set has too high voltage and an alarm occurs, it should be Check the possible reasons for adjustment:

 

       1. The core gap of the shunt reactor is too large. This problem is relatively simple to deal with, and the operator only needs to adjust the thickness of the core gasket.

       Second, the unit speed is too high. Faced with the problem of high unit speed, the operator only needs to reduce the opening of the hydro-turbine hydrofoil.

       3. The magnetic field rheostat is short-circuited. The accurate identification is that when the voltage caused by the short circuit of the magnetic field varistor is too high, there may be a problem of voltage regulation failure at the same time. The operator only needs to directly eliminate the short circuit point.

       4. The crew has a speeding failure. Speeding is a relatively common problem. When the diesel generator set has a speeding problem during use, the operator must stop it urgently and then handle the accident.

 

       The high voltage alarm failure of 400kw diesel generator set is mainly caused by the above four reasons. When users encounter such problems, they can operate according to the above methods. Dingbo Electric Co., Ltd. warmly reminds that when the diesel generator set fails, if you cannot correctly identify the fault If you do not know how to solve the problem by yourself, you must seek professional maintenance personnel in time to deal with it.
