本仪器可对目前广泛使用的200芯及200芯以内的地震覆盖电缆进行自动检测。检测内容包括通断、串线、反向、插头接触不良、短路和线间绝缘漏(电)等。绝缘测试分6档,可根据需要进行选择。本仪器于1987年7月由石油物探局地调二处仪修站研制成功。它性能稳定,测试精度高,测试结果可靠,可满足目前国内地震覆盖电缆检修测试的要求。主要技术指标1.通断档(1)电缆断线及被测芯线电阻加插头接触电阻大于160Ω时,仪器自动停机,同时显示“断线”故障及有故障芯线的编号;
This instrument can automatically detect the seismic coverage cables within 200 cores and 200 cores which are widely used at present. Detection includes on-off, stringing, reverse, bad plug, short circuit and line insulation leakage (electricity) and so on. Insulation test points 6 files, according to need to choose. The instrument in July 1987 by the Geophysical Bureau Geological Survey Station II successfully developed. It has stable performance, high testing accuracy and reliable test results, which can meet the current requirements of overhauling and testing of earthquake-covered cables in China. The main technical indicators 1. On-off (1) cable break and measured core resistance plus plug contact resistance is greater than 160Ω, the instrument automatically shut down at the same time shows the “broken” fault and faulty core number;
