摘　　要：随着中国超特高压的迅速发展,SF_(6) 气体密度继电器在各类电压等级设备中广泛应用。由于电网设备所处的电磁环境复杂,现有SF_(6) 气体密度继电器无法将各类信息准确远传,因此研究一种新型抗干扰远传式SF_(6) 气体密度继电器具有重要的意义。介绍了SF_(6) 气体密度继电器的基本原理,并以分数阶滤波系统为基础,提出了一种新型抗干扰SF_(6) 气体密度继电器,并通过现场试验验证了该设备的可靠性。With the rapid development of ultra-high voltage in China,SF_(6)gas density relay is widely used in various voltage level equipment.Due to the complex electromagnetic environment of power grid equipment,the existing SF_(6)gas density relay can not transmit all kinds of information accurately,so it is of great significance to study a new type of anti-interference remote transmission SF_(6)gas density relay.The basic principle of SF_(6)gas density relay was introduced.Based on the fractional order filtering system,a new anti-interference SF_(6)gas density relay was proposed.The reliability of the device was verified by field test.
