Gb cable rupture can be a more common cable fault in the installation and maintenance work of the daily cable cable integrated wiring system, and many maintenance teachers are also very disgusted with this kind of cable common faults, because the breakpoint of the cable is very inconvenient to find, often in the short term can not find where the breakpoint is. In the traditional concept of dealing with the common faults of cable breakage, the maintenance personnel basically find the breakpoint according to the method of checking the breakpoint by segment, and further solve the common faults of cable breakage. In the modern cable break point common fault detection, maintenance personnel generally use what method to check where the cable break point is?

According to the detailed introduction of the integrated wiring system manufacturer Licuntong, at this stage, the common way for cable maintenance workers to find the breakpoint of the broken cable has the following categories:

1, induction test pen test search method. In this way, the switching power supply around the breakpoint cable is generally cleared first, and then connected to the neutral line of the fireline, and the test pen is vertical with the power line, and the test pen detection button is pressed, and the breakpoint of the cable can be identified when the communication and communication data signal occurs and suddenly fades.

2. Search with audio detector. It is an instrument that identifies common faults of national standard cable routes according to data signals. When it is used to track the cable route, the break point of the cable can be distinguished without peeling the cable skin.

3, use the cable fault test detector to search. According to the cable fault test and detection instrument can accurately measure the exact position of the common fault point, suitable for testing a variety of cable models and specifications.

4, the application of curve measurement search. That is, the breakpoint cable is received on the digital multimeter, and the resistor is hit on the 200Ω, if the sheet metal is bent in the area that may be disconnected, such as Wan Yongbiao indicates that the sheet metal is bent as the breakpoint of the cable line.

In the contemporary national standard cable line breakpoint common fault detection, basically all are carried out in accordance with the above four ways, but under the standard, I or propose that we rely on experimental instruments to test the breakpoint of the cable line to improve work efficiency.
