The relay of the cylinder valve at the Ahai hydropower station has the disadvantage of leakage,which can easily cause the relay to be unable to synchronize and cause abnormal cylinder valves.This paper provides a detailed analysis of the causes of leakage in the relay,and conducts a comprehensive disassembly inspection of the relay during unit maintenance to determine the final cause of the malfunction.By implementing a series of targeted maintenance measures,the leakage rate is successfully reduced and the reliability of the cylinder valve operation is improved.
