摘　　要：有效监测气体绝缘组合电器变电站的SF6气体泄漏,对于保证变电站工作人员和环境安全至关重要。目前的SF6泄漏报警装置传感器模块均需要接电源线和通讯线,通过有线方式将传感器模块监测的数据传输至大门外主机,分布的监测模块采用有线方式,存在不美观、装好后移动困难及维修不易等问题。因此,提出基于Lo Ra的SF6泄漏报警监测技术,研制出基于Lo Ra技术的SF6泄漏报警监测装置,并进行了相关测试,测试结果表明,研制的装置参数符合该领域检测要求。Effectively monitoring the sulfur hexafluoride(SF6) gas leakage of a gas-insulated switchgear is important to ensure the safety of substation staff and the environment.At present,a SF6 leak alarm device needs to connect the power and communication lines to transmit the monitoring data of sensor module to the host.However,some drawbacks,such as difficulty in installing the monitoring module using wired mode,there are aesthetic defects,immovability,and difficulty in maintenance,are encountered in this process.In this study,a SF6 leak alarm monitoring device based on LoRa technology is proposed and developed,and relevant tests are conducted.Test results show that the test parameters of the proposed device meet the test requirements in this field.
