【摘要】：在向露天礦大型移動(dòng)用電設(shè)備遠(yuǎn)距離輸送高壓動(dòng)力電的線路中,地線的良好連接至關(guān)重要,否則會(huì)造成嚴(yán)重的安全事故。文章通過(guò)在移動(dòng)變電站中安裝主監(jiān)控裝置,在每一個(gè)移動(dòng)開(kāi)關(guān)柜中安裝檢測(cè)控制裝置,組成地線連接狀態(tài)實(shí)時(shí)監(jiān)測(cè)及故障定位系統(tǒng)。主監(jiān)控裝置和檢測(cè)控制裝置之間通過(guò)檢測(cè)控制線進(jìn)行載波通信,主監(jiān)控裝置根據(jù)檢測(cè)控制裝置上傳的信息判斷線路中地線連接狀態(tài),一旦發(fā)現(xiàn)連接故障,就顯示故障位置信息并聲光報(bào)警,提示工作人員及時(shí)進(jìn)行高壓電斷電操作,并且在提示的區(qū)域查找故障。本文設(shè)計(jì)的線路監(jiān)測(cè)及故障定位系統(tǒng)與電橋檢測(cè)方法相比,能夠減少故障的誤報(bào)率,縮短查找故障的時(shí)間。
[Abstract]:In the transmission line of high voltage power to large mobile electric equipment in open pit mine, good connection of ground wire is very important, otherwise it will cause serious safety accident. In this paper, the main monitoring device is installed in mobile substation. A detection control device is installed in each mobile switchgear to form a real-time monitoring and fault location system for the ground connection status. The carrier communication between the main monitoring device and the detection control device is carried out through the detection control line. The main monitoring device judges the connection status of the ground line in the line according to the information uploaded by the detection and control device. Once the connection failure is found, the fault location information is displayed and the acousto-optic alarm is reported, which prompts the staff to carry out the high-voltage power cut operation in time. The circuit monitoring and fault location system designed in this paper can reduce the false positive rate of fault and shorten the time of finding fault compared with the bridge detection method.
