感應(yīng)通信式礦用饋電狀態(tài)傳感器設(shè)計(jì)

為了進(jìn)一步提高煤礦井下饋電狀態(tài)傳感器的性能,通過(guò)對(duì)煤礦井下特殊情況、饋電狀態(tài)傳感器的理論探索和現(xiàn)有應(yīng)用的研究,根據(jù)《礦井安全監(jiān)控新標(biāo)準(zhǔn)、新規(guī)程匯編》的要求[1 ] ,首次提出一種感應(yīng)通信式饋電狀態(tài)傳感器,它是根據(jù)電壓互感器原理和無(wú)線通信原理來(lái)實(shí)現(xiàn)的,從而間接檢測(cè)礦井電纜的饋電狀態(tài),與負(fù)載是否工作,電纜有無(wú)電流流過(guò)無(wú)關(guān),只要電纜芯線帶電,則輸出饋電狀態(tài);反之,輸出非饋電狀態(tài). 這種感應(yīng)通信式饋電狀態(tài)傳感器具有靈敏度高、反映迅速、可靠性高以及維護(hù)量少等特點(diǎn).

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.
