感應通信式礦用饋電狀態傳感器設計

為了進一步提高煤礦井下饋電狀態傳感器的性能,通過對煤礦井下特殊情況、饋電狀態傳感器的理論探索和現有應用的研究,根據《礦井安全監控新標準、新規程匯編》的要求[1 ] ,首次提出一種感應通信式饋電狀態傳感器,它是根據電壓互感器原理和無線通信原理來實現的,從而間接檢測礦井電纜的饋電狀態,與負載是否工作,電纜有無電流流過無關,只要電纜芯線帶電,則輸出饋電狀態;反之,輸出非饋電狀態. 這種感應通信式饋電狀態傳感器具有靈敏度高、反映迅速、可靠性高以及維護量少等特點.

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.
