Cable open-circuit fault locating device

Abstract

The invention discloses a cable open-circuit fault locating device. The device comprises a host computer and a cable open-circuit detector. The cable open-circuit detector includes a main controller module, a cable open-circuit detection module, a GPRS location module, an alarm module and a power supply module, wherein the main controller module is connected with the cable open-circuit detection module, the GPRS location module and the alarm module respectively; the power supply module is connected with the main controller module, the cable open-circuit detection module, the GPRS location module and the alarm module respectively; and the cable open-circuit detector is connected with the host computer through the GPRS location module. By using the cable open-circuit fault locating device provided by the invention, the specific location of a cable open-circuit fault can be determined at the first time to inform the first-aid repair personnel to get to the position of the fault to perform first-aid repair, so that the work load of the working personnel is reduced, and the working efficiency of the working personnel is increased, thereby improving the service quality of power supply.

Description

technical field [0001] The invention belongs to the technical field of power electronic detection, in particular to a cable disconnection fault location device. Background technique [0002] With the shortage of social economy and urban land space, more and more cable power supply lines are replacing the original overhead power supply lines. The cable power supply line has the characteristics of not occupying the channel space and not affecting the urban environment; but at the same time, because it runs underground, once a fault occurs, it has the disadvantage of being harder to find than the fault of the overhead power supply line, and more than 95% of the cable fault types are caused by external force damage ( Such as urban construction, pipe trench excavation, etc.) caused by cable disconnection fault. [0003] After a fault trip occurs in the operation of the cable power supply line in the prior art, the monitoring personnel and emergency repair personnel can only dete...
