[0002] As a device for determining the location of underground cable faults, the precise locator plays a key role in the daily emergency repair construction of power companies. Its appearance has greatly improved the work efficiency of operation and maintenance personnel. In the power industry, using a precise locator to preliminarily determine the fault location is a simple means to avoid the need to repeatedly excavate the construction site, thereby damaging the cable line or even other pipelines.

[0003] At present, the precise locating instrument widely used in various power companies is a handheld device set, which consists of a height-adjustable telescopic handle, a detector, headphones, a receiver, and a detector connecting cable. In actual operation, the operation and maintenance personnel hold the receiver and repeatedly move the instrument according to the indication of the cable position and the fault position on the LCD screen, and finally locate the cable fault. In this process, not only do the operation and maintenance personnel need to continuously operate the precise locating instrument for detection, but they also need to continuously listen to the sound from the headphones to assist in judging different fault types and fault locations, which is time-consuming and labor-intensive. Not only is the work efficiency low, the labor intensity is high, and the detection results will be affected by the subjective judgment of the operation and maintenance personnel. If the operation and maintenance personnel are negligent or lack experience during the operation, the positioning results will be greatly deviated from the actual fault location. Therefore, a new type of automatic precise locating device for cable faults is urgently needed to solve the above problems. Summary of the invention
