The cooling methods commonly used include air cooling, hydrogen cooling and water cooling. Although the effect of the air cooler is poor, the air cooling equipment is simple and works reliably, so that medium and small generator sets are adopted more. The air cooler cools the air discharged from the generator and having a high temperature by using the cooling water, and then sends the air to the generator. When the generator works, the generated heat is taken away by cooling water, and the air plays a role as a medium.

The upper part of most air coolers is generally provided with an exhaust valve for exhausting air in a pipeline when the air cooler operates, and the exhaust valve has two types of manual control and automatic control. Because manual exhaust valves need to be operated manually each time, most hydroelectric generating sets currently adopt automatic exhaust valves arranged on the top of an air cooler. However, in recent production operation, it is found that when a cooling water leakage problem occurs due to low reliability of an automatic exhaust valve, a generator is easy to be affected with damp to generate faults such as grounding, and the accidents such as non-stop of the generator set are more and more caused, because the installation position of the exhaust valve of the air cooler is generally very close to the outlet position of the generator or the neutral point position of the generator, once the exhaust valve falls off or water is sprayed in a blocking manner, the safe operation of the generator set is seriously affected, and the accidents such as non-stop or damage to electrical equipment are possibly caused.
