Moisture prevention is an important measure to ensure stable operation and extend the service life of large generator set. Here are several key points to pay attention to when preventing moisture:
1. Selection and Construction of Large Generator Set Environment
Site selection: Diesel generator sets should be installed in areas with relatively high terrain, low water accumulation, and good ventilation to reduce the risk of moisture.
Drainage system: a complete drainage system shall be established around the equipment, such as drainage ditches, collecting wells and drainage pumps, to ensure the rapid drainage of accumulated water in severe weather such as rainstorm.
2. Large generator set protection
Waterproof measures: Apply waterproof coating or install waterproof cover on the surface of the large generator set to reduce direct erosion of the equipment by rainwater.
Ventilation and drying: Maintain good ventilation conditions around the computer room or equipment, use dehumidifiers or air conditioners to control indoor humidity, and ensure a dry environment.
3. Regular inspection and maintenance of large generator sets
Insulation resistance testing: Regularly check the insulation resistance of the generator set, and promptly deal with any decrease in insulation resistance to avoid electrical faults caused by moisture.
Sealing inspection: Check the sealing of the equipment to ensure that there is no water leakage or seepage. At the same time, check the operation status of the fan and whether the radiator is blocked to improve the heat dissipation effect.
4. Large generator set emergency response
Develop emergency measures: During the rainy or humid season, develop emergency response measures. Once the generator set is found to be damp or malfunctioning, it should be immediately stopped and inspected.
Drying treatment: If there is moisture inside the large generator set, hot air method can be used for drying. The specific method is to remove all cover plates of the generator set, use a hair dryer to blow air from the air inlet inward, pay attention to controlling the surface temperature of the winding, and avoid insulation damage caused by overheating.
5. Storage and Preservation of Large Generator Sets
Spare parts and tools: When storing cables, tools, spare parts, and other items in the computer room, make sure they are dry to avoid equipment failure caused by moisture.
Long term idle: For generator sets that have been idle for a long time, regular start-up and operation checks should be conducted to maintain their performance and condition.
Moisture prevention for large generator sets requires comprehensive consideration and implementation from multiple aspects, including environmental selection, equipment protection, regular inspection and maintenance, emergency response, and storage and preservation.
Through these measures, the risk of moisture damage to the generator set can be effectively reduced, ensuring its stable operation and extending its service life.
