SF_(6)密度继电器实验室校验方法

Laboratory Calibration Method of SF_(6)Density Relays

SF_(6)密度继电器是SF_(6)电气设备的重要器件之一,定期对SF_(6)密度继电器进行校验是保障电力设备安全可靠运行的必要措施。随着数字式SF_(6)密度继电器的推行,现有的校验方法已无法满足其校验要求。为此,提出了SF_(6)密度继电器实验室校验方法,通过搭建高低温校验平台对SF_(6)气体密度继电器进行性能校验,结果表明该校验平台满足数字式SF_(6)密度继电器和传统机械式SF_(6)密度继电器的校验要求,弥补了传统密度继电器校验项目的不足,对支撑SF_(6)密度继电器数字化改造具有重要意义。

SF_(6)density relays are a kind of important components of SF_(6)electrical equipment,and regular calibration of SF_(6)density relay is a necessary measure to ensure safe and reliable operation of power equipment.With the implementation of digital SF_(6)density relays,the existing calibration methods have become inadequate.In this paper,the laboratory calibration method of SF_(6)density relays is proposed,and the performance calibration of SF_(6)gas density relay is performed by establishing a high and low temperature calibration platform.The calibration platform is verified competent in calibration of digital SF_(6)density relays and conventional mechanical SF_(6)density relays,and may be useful in digitalizing of SF_(6)density relays.
