The fault test of the buried cable fault detector uses the buried cable fault detector manufacturer The buried cable fault detector adopts a variety of detection methods and applies contemporary advanced electronic technology achievements. Using computer technology and microelectronics technology, the fault test of the buried cable fault detector with an intelligent degree uses the buried cable fault detector manufacturer. The buried cable fault detector adopts a variety of detection methods and applies contemporary advanced electronic technology achievements. Using computer technology and microelectronic technology, it has the characteristics of high intelligence, complete functions, wide application range, accurate testing and convenient use.
Buried cable fault detector is composed of transmitter and receiver, inductive probe, potential difference detection frame, etc. The instrument uses electromagnetic induction method to conduct routing tracing and buried depth test on optical cable and cable, and uses potential difference method to conduct fault location test on optical cable and cable. It is suitable for all kinds of optical cables with metal conductors (pairs, sheaths, shielding layers), routing of cables, buried depth and location testing of poor insulation points to the ground.
It is a special tester for line faults in post and telecommunications systems, railways, mines, oil fields, airports, shipping and other units. The whole set of buried cable fault detectors can be used together to quickly determine the nature of the fault, the distance from the fault point to the test end, locate the fault point, search for the path and depth of the buried cable, and detect the transmission speed of the unknown medium cable. The full length of the entire cable and the position of the joints, identify the faulty cable among several cables. One set of instruments for many purposes.
Buried cable fault detector fault test: The basic steps of fault test: measure the insulation resistance of the faulty cable with a shaker or a multimeter, judge the nature of the fault, and determine the test method; test the fault distance; detect the path of the cable buried near the fault point; fix the point. The fault test of this test system has three basic methods: low-voltage pulse, direct flash, and rush flash. Combined with different sampling methods, there are a total of eight test methods. Disconnect all wires from the cable terminations before testing.
The panel of the test system has“input amplitude”and“displacement”Two knobs are used to adjust the signal amplitude and the upper and lower positions of the next sampling respectively. The buried cable fault detector makes it integrate the essence of various detection instruments at home and abroad. It has the characteristics of low price and is loved by the majority of agricultural line maintenance workers. It is an essential maintenance instrument tool for every agricultural power department, geographic line users and rural electricians. Shenzhen Noyafa Electronic Technology Co., Ltd.
