近年来,许多矿工由于拖曳电缆漏电而死亡或受伤,而各种电缆漏电检测仪器价格昂贵,体积又大,使用起来很不方便。最近,美刊《煤时代》(CA10/81P155)报道:美国煤矿安全与保健局下属宾夕法尼亚洲普鲁士顿科研小组研制成了能检测电缆极微量漏电的电缆检测仪。这种检测仪既可检测交流电路中的漏电,也可检测直流电路中的漏电。下面介绍的是怎样只化25美元制作这种新式电缆漏电检测仪的具体方法。 In recent years, many miners have been killed or injured as a result of trawl cable leakage. Various types of cable leakage testing instruments are expensive, bulky, and inconvenient to use. Recently, the US publication Coal Times (CA10 / 81P155) reported that Prussia Scientific Research Institute, a subsidiary of the U.S. Coal Mine Safety and Health Administration, has developed a cable tester capable of detecting trace leakage of cables. This detector can detect leakage in the AC circuit can also detect leakage in the DC circuit. The following is how to make only 25 US dollars to make this new cable leak detector specific way.
