石油三厂总机动师室,原有三年文化的电工曹福连,经过二年多的苦心钻研,先后试验了三十八次,战胜了种种因难,在改进电缆试验器的基础上改制成了精确的电缆探伤器。电缆探伤器,构造简单,准确性能高,造价低廉,装制一台祗需20多元钱的电器零件。用它可判断接地或相间短路,能区别故障性质,凡是有电缆设备的工业及交道运输业都能广泛应用。电缆探伤器构造共分三部分:一、震荡器,用电磁线圈串联(?)电容器,以九伏特的干电池作电源,把电源接在故障的回路上,因通过电流而产生音响;二、听音器:用电讯耳机,装上感应线圈,接在探测棒上,沿故障线探测,因震荡
After three years of painstaking research, Cao Fulian, the original three-year cultural electrician, has experimented for thirty-eight times in succession to overcome all kinds of difficulties. On the basis of improving the cable tester, the system was restructured into an accurate Cable Flaw Detector. Cable detector, simple structure, high accuracy, low cost, the installation of a just 20 yuan more than the electrical components. Use it to judge the ground or short circuit, can distinguish the nature of the fault, usually cable equipment, industrial and transportation industry can be widely used. Cable detector structure is divided into three parts: First, the oscillator, the solenoid coil in series (?) Capacitor to nine volts of dry batteries for power supply, the power supply connected to the fault circuit, due to the current generated by the sound; Second, listen MUSIC: Using telecommunications headphone, mounted on the induction coil, connected to the detection rod, along the fault line detection, due to shock
