How to dry a damp generator set?

High humidity in the air or staff errors may causeGenerator setDampness will cause the insulation resistance performance of the generator set to decrease, and there are hidden dangers. How to dry the generator set is a problem that needs to be faced. Below, Haixing will introduce to you the specific methods of drying the generator set:

Directly short-circuit the three-phase terminals of the stator winding of the generator set to ensure a secure connection. Adjust the maximum resistance position of the voltage-regulating transformer in the excitation circuit. If the resistance is not large enough, connect another resistor to increase the resistance. Then start the generator set, pay attention to slowly accelerating to the rated speed, and then slowly adjust excitation current. The excitation current is determined based on the dampness of the generator set. However, the stator winding short-circuit current must not exceed the rated current.

In addition, the ventilation conditions of the generator storage environment must be improved and good ventilation equipment must be provided. In cold seasons, backup heating equipment must be installed in the warehouse to ensure that the temperature in the warehouse is not lower than 5°C. It is strictly forbidden to allow nearby water to drip into the inside of the generator set. For generator sets using 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 short-circuited with a wire to prevent breakdown during measurement.

The above are the specific methods of drying damp generator sets brought by Haixing. When the rainy weather is coming, I hope that the drying treatment method of generator sets introduced by Haixing can help you solve the problem. At the same time, Haixing also hopes that everyone will do Take good moisture-proof measures to ensure the normal operation of the generator set!
