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.
