I/O System 2000仪器排列特殊故障的判断分析

Judgement and analysis of special breakdown on spread of I/O system 2000 instrument .

System 2000是目前世界上最先进的遥测地震仪。不过,在排列中,查线时经常出现交叉站的一端只能带动56个站的现象。这一特殊故障主要是外线故障和电源站故障引起的。通过分析、判断,故障若在大线,换掉故障大线后排列正常;故障若在电源站,则检查电源线的正负极连接情况,并通过改装电源线,有效地排除故障。

System 2000 is most advanced Telseis in the world up-to-now . But the phenomenon that the one end of cross station only drives 56 stations often appears during checking spread . This special breakdown mainly caused by the breakdown both in geophone cable and in power station . After analysis and judgement , if the breakdown is in geophone cable , the spread is OK after changing the damaged cable ; if the breakdown is in power station , checking the connection of positive/negative pole on power line and refitting the power line , the breakdown is effectively removed .
