Description

Accurate positioner of trouble cable Technical Field The utility model relates to the technical field of cable detection, in particular to a fault cable accurate positioning device. Background At present, in the cable production and manufacturing process, a fault cable is unavoidable. For short-circuit fault cables, positioning methods with mature technology and high precision already exist on the market. However, for the broken fault cable, the current method is to roughly locate by using a capacitance method to determine an approximate position, and then manually and slowly find the broken position. The method has the defect of poor positioning accuracy, different errors for cables of different types and specifications, and even some cables can have errors of hundreds of meters, which brings great difficulty to quickly searching fault points and maintaining. Disclosure of utility model The utility model aims to overcome the existing defects, and provides a fault cable accurate positioning device which can effectively solve the problems in the background technology. In order to achieve the aim, the utility model discloses a fault cable accurate positioning device which adopts the technical scheme that the fault cable accurate positioning device comprises a pay-off rack and a pay-off rack, wherein the pay-off rack further comprises two groups of support units, and a winding roller is arranged between the two groups of support units; A lifting frame is further arranged between the wire collecting frame and the pay-off frame, the lifting frame is arranged on one side close to the wire collecting frame, and an induction coil is arranged on the lifting frame; The utility model discloses a cable is connected with the battery through the mounting panel on the pay off rack, the battery is for waiting to detect the cable and provides the alternating current, adopts pay off rack and pay off rack, the cooperation of battery, under the prerequisite that does not influence the rolling of cable, treat the cable of detecting and lets in the alternating current, because the circuit breaking of cable, the alternating current stops in the department of breaking circuit, through induction coil, detects whether have the alternating current in the cable, can judge the position that the cable was broken circuit, can be quick, accurate find the fault position of breaking circuit trouble cable and maintain.
