摘　　要：作为重要的气体密度监测装置,SF_(6)气体密度继电器的性能好坏直接影响电气设备的安全运行。针对SF_(6)气体密度继电器在实际应用中发现的监测数据不准确、密度继电器接点误导通、产生故障电弧和漏油等缺陷问题,可通过校验监测数据、增加接点信号的延迟传输及改进部件等方法来诊断,这对保障SF_(6)气体密度继电器稳定可靠运行有着重要的意义。As an important gas density monitoring device,SF_(6) gas density relay directly determines the safe operation of electrical equipment.Giving consideration to the defects found in the practical application of SF_(6) gas density relay,such as inaccurate monitoring data,improper conduction of density relay contact,fault arc generation,and oil leakage,this paper proposes diagnoses by means of verifying monitored data,increasing delayed transmission of contact signals,and improving components.Appropriate fault diagnosis is of great significance to ensure the stable and reliable operation of SF_(6) gas density relay.
