摘　　要：随着中国智能电网的不断大力发展,远传式SF_6气体密度继电器也是核心和关键部件,针对目前使用的远传式SF_6气体密度继电器存在的缺陷,为了克服这些缺陷,提出并研制了一种高抗干扰的远传式SF_6气体密度继电器,通过试验验证和现场运行,该密度继电器能够可靠的在电磁干扰强的变电站中对SF_6气体密度实行监测和远传,从而保证供电设备的安全可靠运行。With the continuous development of smart grid in China, remote SF6 gas density monitor is also the core and key components, in view of the defects of the remote transmission SF6 gas density monitor currently used, in order to overcome these defects, a high anti-interference and remote transmission SF6 gas density monitoris proposed and developed, through the test verification and field operation, the density relay can reliably monitor and transmit the SF6 gas density in the substation with strong electromagnetic interference, so as to ensure the safe and reliable operation of power supply equipment.
