电接点密度继电器存在的主要问题及改进措施
|
摘要
SF_6气体密度继电器作为监测运行设备中SF_6气体密度变化的重要元件,其性能的好坏直接影响着SF_6电气设备的安全运行。文中针对运行中的磁助式电接点的SF_6气体密度继电器接点不能可靠导通以及漏油现象进行分析,找出了原因,并提出了具体的整改措施。经过3年多的现场应用证明其整改措施是非常有效的。
SF_6 gas density monitor is an important instrument for monitoring SF_6 gas density in electrical equipment,and its performance directly affects safe operation of the SF_6 electrical equipment.In this study,the problems of unreliable conduction of magnetic snap contact and oil leakage were analyzed,the causes were found,and corresponding countermeasures were offered.Execution for three years verified the effectiveness of the countermeasures.
