cy3型液压操作机构常见故障的原因分析及处理方法（Cause analysis and treatment method of common faults of Cy3 hydraulic operating mechanism） Cause analysis and treatment of common faults of CY3 hydraulic pressure operation machine 2009-3-27 Abstract: through the analysis of several failure reasons of hydraulic operating mechanism for high-voltage circuit breaker is common, and puts forward some methods, the corresponding fault handling procedures. Equipment management, equipment maintenance, detection and diagnosis of 24Z China equipment management network jFa Keywords: fault treatment of hydraulic operating mechanism for high-voltage circuit breaker reasons Equipment management, equipment maintenance, detection and diagnosis of 24Z China equipment management network jFa Equipment management, equipment maintenance, detection and diagnosis of 24Z China equipment management network jFa At present, Binhai County, Binhai Power Company substation 110, 35kV switch operating mechanism with hydraulic operating mechanism of CY3. CY3 hydraulic mechanism has the advantages of small size, big power, but because the running time of the circuit breaker is longer, mostly for more than 10 years, some parts of the hydraulic operating mechanism of aging, the failure rate was significantly higher than that in spring and electromagnetic operating mechanism. Some problems are still quite prominent and frequent, serious impact on the reliability of the product. Switch operating mechanism and often sudden failure. Only 110kV Binhai Fault substation, operating mechanism of various types of switches up to 18 times it happened in 2006. Sometimes the same operating mechanism in a few days or even on the same day for failure. As the processing method to help the operator to control the faults of CY3 hydraulic system, the following will analyze cause of this type of operating mechanism often appear in what I use, and discusses the processing method. Equipment management, equipment maintenance, detection and diagnosis o
