The invention discloses a cable breakage detection instrument which comprises a 6V direct-current power supply, a detection circuit, an astable multi-oscillation circuit and an audio signal output circuit, and is characterized in that the selected and used type of a time-based circuit in the astable multi-oscillation circuit is NE555. A professional cable breakage fault test positioning instrument comprises a breakpoint distance measurement part, a breakpoint accurate positioning signal source and a breakpoint accurate positioning detector, and has the characteristics of full-digital displaying, high system integration degree, small volume, low weight, portability and the like. By the cable breakage detection instrument, a subjective error of a pointer-type detection instrument due to manual scale checking is eliminated, and the position of a cable breakpoint still can be accurately found out even by working personnel without practical experience. But the professional cable breakage fault test positioning instrument has the problems of high price, difficulty in popularization within the working range of cable maintenance, electricians, and the like. The cable breakage detection instrument disclosed by the invention has the characteristics of low price, high practicality, reliable detection result and easiness of popularization.
Description
technical field [0001] The invention belongs to the field of electronic technology and cable maintenance, and relates to a cable disconnection detector. Background technique [0002] The professional cable disconnection fault test locator is composed of three parts: digital breakpoint distance measurement, breakpoint fine location signal source, and breakpoint fine location detector. The instrument has the characteristics of breakpoint distance measurement, breakpoint fine positioning signal source breakpoint fine positioning detector, full digital display, high system integration, small size, light weight, and easy to carry. It overcomes the subjective error of manual calibration of the pointer detector, and even inexperienced personnel can accurately find the location of the cable breakpoint. [0003] However, the professional cable disconnection fault test locator has problems such as high price and difficulty in popularization in the field of cable maintenance and elect...
