感应通信式矿用馈电状态传感器设计为了进一步提高煤矿井下馈电状态传感器的性能,通过对煤矿井下特殊情况、馈电状态传感器的理论探索和现有应用的研究,根据《矿井安全监控新标准、新规程汇编》的要求[1 ] ,首次提出一种感应通信式馈电状态传感器,它是根据电压互感器原理和无线通信原理来实现的,从而间接检测矿井电缆的馈电状态,与负载是否工作,电缆有无电流流过无关,只要电缆芯线带电,则输出馈电状态;反之,输出非馈电状态. 这种感应通信式馈电状态传感器具有灵敏度高、反映迅速、可靠性高以及维护量少等特点.For t he sake of more enhancing capabilities of feedback elect ricity t ransducer , based on t he special instances of coal mine , t he t heory exploring and existing application researching on t he feedback elect ricity transducer developed a new type feedback elect ricity t ransducer . It works on t he power t ransformer principle and t he radio2communication p rinciple , and supervises t he feedback elect ricity states of mine well cableline indirectly. This kind of inspecting way is irrespective wit h load whet her it is working or not and cableline whet her it has elect rical current or not . If only when cable2line has elect ricity , t hen t ransducer outp utt he state of feedback elect ricity or el se t he none2state of feedback elect ricity. This t ransducer is in accordance with The Compilation of New Standards and New Regulations in Mine Security Monitoring. It s char acteristics are high2sensitivity , reflection2rapidness , high2reliability , asymaintenance , etc.
