Description
Technical field
The utility model relates to a kind of simple and easy cable fault orientator.
Background technology
At present cable fault point position measurement method is mainly contained two kinds of the process of chopping and ultrasonic methods: the process of chopping is that whether malfunction elimination is carried out in conducting through measuring it through cutting off cable; This method is bothersome, time-consuming; And when finding open circuit fault point, former cable possibly be divided into plurality of sections; Ultrasonic method is to utilize ultrasonic transmission device to fault cable emission ultrasound wave; Because ultrasound wave runs into breakpoint and can return; Thereby can calculate the cable breakpoint location through its travel-time, its accuracy of detection is high, and can not damage cable; But ultrasonic device is complicated, cost an arm and a leg, affected by environment big, uses inconvenience.
The utility model content
Goal of the invention: in order to overcome the deficiency that exists in the prior art, the simple and easy cable fault orientator that the utility model provides a kind of and manipulates simply, cable do not damaged is accurately located the breakpoint fault of cable.
Technical scheme: for solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of simple and easy cable fault orientator; Comprise cable distributed capacitance metering circuit, distributed capacitance/voltage conversion circuit, A/D change-over circuit, numerical evaluation circuit and output display circuit; The output terminal of said cable distributed capacitance metering circuit connects the input end of distributed capacitance/voltage conversion circuit; The output terminal of distributed capacitance/voltage conversion circuit connects the output terminal of A/D change-over circuit; The output terminal of A/D change-over circuit connects the input end of numerical value counting circuit, and the output terminal of numerical evaluation circuit connects the output display circuit.
Measure the distributed capacitance of cable through the cable distributed capacitance after; Can convert the voltage signal that is directly proportional with distributed capacitance to through distributed capacitance/voltage conversion circuit; Convert voltage signal to numerical signal through the A/D change-over circuit again; Can calculate by the logarithm value signal through the numerical evaluation circuit, we know that the size of distributed capacitance and the length of cable are proportional, thereby can conveniently calculate the non-fault length of cable; And, make things convenient for the staff that the cable fault point is positioned through output display circuit display result.
Beneficial effect: the simple and easy cable fault orientator that provides of the utility model, device simple, easy to use can accurately be located the cable fault point cable not being destroyed under the prerequisite.
