Reasons for High Voltage Alarm Failure of 400kw Diesel Generator Set

Sep. 02, 2021

The 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. In use, when the 400kw diesel generator set has an alarm due to excessive voltage, the following four possible causes should be checked and adjusted.

 

Diesel generator set is a kind of large-scale precision mechanical equipment. Most users are not experts in this area. Therefore, it is inevitable that they will encounter various problems during use. For example, the high voltage alarm failure of 400kw diesel generator set is the comparison among users. Frequently encountered problems, then this article, generator manufacturer Dingbo Power, will specifically talk about the causes and treatment methods of high-voltage alarm failures of 400kw diesel generator sets.

 

Reasons for High Voltage Alarm Failure of 400kw Diesel Generator Set


We all know that a high-quality diesel generator set can bring stable output power. Excessive or low voltage may affect the use of diesel generator set. When a 400kw diesel generator set has an alarm due to excessive voltage, the following should be taken Check and adjust for possible reasons:

 

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 iron core gasket.

 

2. The speed of the unit is too high. Faced with the problem of excessively high speed of the unit, the operator only needs to reduce the opening of the hydroturbine guide vane.

 

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

 

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

 

The high-voltage alarm failure of 400kw diesel generator set is mainly caused by the above four reasons. When encountering such problems, users can operate according to the above methods. Top Power Warmly reminds that when the diesel generator set fails, if you cannot correctly identify the fault The reason, if you don’t know how to solve it by yourself, you must find professional maintenance personnel to deal with it in time, do not operate without authorization, so as not to cause greater failure, if you need help, welcome to contact Dingbo Power by dingbo@dieselgeneratortech.com.
