摘要
本文文绍了刘家峡水电站电机通风系统的改造情况。通过改用无风扇端部回风通风结构等措施解决了老式电机风量大、损耗高、安全差和检修不便等问题.给老电机的通风改造提供了成功经验。
Here is deseribed the ventilation system modification for hydrogenerator in Liujiaxia power station by the use of construction of getting rid of fans and letting the cooling air go back through the end parts. Some old problems were getting solved such as excessive air, high losses, less safety and unconvenient maintenance. It presented a successful and available modification experience for old hydrogenerators.
