How to dry the damp generator set?

Heavy humidity in the air or mistakes of staff may cause the generator set to be damp. The damp generator set will lead to a decrease in its insulation resistance performance, which poses a hidden danger. How to dry the generator set is a problem that needs to be faced. Now Haixing will introduce you to the specific methods for drying the generator set:

The three-phase outlet of the generator set stator winding is shorted directly to ensure a reliable connection. Modify the maximum resistance position of the voltage regulator converter in the excitation circuit. If the resistance value is not large enough, another resistor should be connected to increase the resistance value. Then start the generator set, pay attention to slowly accelerating to the rated speed, and then slowly adjust the excitation current. The excitation current is determined based on the moisture condition of the generator set, but the short-circuit current of the stator winding shall not exceed the rated current.

In addition, the ventilation conditions of the storage environment of the generator set must be improved and good ventilation equipment must be prepared. In the cold season, heating equipment must be installed in the warehouse to ensure that the temperature in the warehouse is not lower than 5℃. It is strictly forbidden for nearby water to drip into the generator set around the generator set. For generator sets with semiconductor excitation methods, when measuring the insulation resistance of the excitation circuit, the excitation device should be disconnected, or each silicon rectifier element should be shorted with wires to prevent it from being broken down during measurement.

The above is the specific method of drying the damp-affected generator set brought by Haixing. When the plum rain weather is approaching, I hope that the drying treatment method of the generator set introduced by Haixing can help you solve the problem. At the same time, Haixing also hopes that everyone should take moisture-proof measures to ensure the normal operation of the generator set!
