The invention discloses a
power cable fault positioning platform, including a cable fault
detector arranged on a
power cable, a
signal back-transmission mechanism, a mobile monitoring
station and a mobile monitoring unit. The mobile monitoring unit comprises an overhead track and a mobile mechanism wherein the mobile mechanism is provided with a monitoring terminal; the
signal back-transmission mechanism comprises a communication line arranged in a cable conduit and a number of
wireless receivers; the fault
detector is provided with a first
wireless communication module; the monitoring terminal comprises a control module, a second
wireless communication module, a storage module, a sensor module, a
video monitoring module and wireless emitters arranged correspondingly to the wireless receivers; and the mobile mechanism is provided with a plurality of fault positioning mechanisms through an ejection mechanism. The platform of the invention performs comprehensive monitoring to the cable fault through the real-time acquisition of online current by the fault
detector and through the fault point positioning, allows the workmen to quickly find the specific fault position so as to realize the rapid maintenance to the fault point.
