摘　　要：处于复杂电磁环境下的电网设备,其SF6数据信息在远传过程中会受到一定程度的干扰,因此研究一种抗干扰远传式SF6气体密度继电器非常重要。介绍了SF6气体密度继电器的基本原理,并以RS-485通信技术为基础,探讨了基于RS-485的远传式SF6气体密度继电器。In the complex electromagnetic environment, the SF6 data information of power grid equipment will be disturbed to a certain extent in the process of remote transmission. Therefore, it is very important to study an anti-interference remote SF6 gas density relay. The principle of RS-485 gas relay based on RS-485 is introduced. Based on RS-485 communication technology, the remote transmission SF6 gas density relay based on RS-485 is discussed.
