Abstract

The invention discloses a device and a method for detecting the position of a cable intermediate joint. The device comprises an acquisition unit for acquiring current position information of the cable intermediate joint carrying electronic mark information through a positioning signal of a satellite, a judgment unit for judging whether the cable intermediate joint is moved or not according to the current position information, a generation unit for generating trigger information, a transmitting unit for transmitting the trigger information and the electronic mark information and a mobile detector for receiving the trigger information and the electronic mark information. The trigger information is generated by acquiring the current position information of the cable intermediate joint carrying the electronic mark information after movement, and the trigger information and the electronic mark information are transmitted to the mobile detector so as to quickly and accurately position the position of the cable intermediate joint, simultaneously reduce the time for searching the cable intermediate joint, reduce the supervision difficulty of maintenance staff, save municipal cost and further ensure the normal operation of a cable line.

Description

technical field [0001] The invention relates to the field of power cables, in particular to a device for detecting the position of an intermediate joint of a cable and an implementation method thereof. Background technique [0002] With the transformation of urban and rural power grids, overhead power distribution lines are gradually replaced by cable lines. As we all know, compared with overhead power distribution lines, cable lines have the advantages of being less affected by the external environment, safe, reliable, concealed, and durable. Therefore, cable lines Widely used in industrial and mining enterprises, urban landscape streets and high-rise buildings and so on. [0003] In the cable line, due to the limited length of a single cable and the presence of distributed capacitance when the cable is long, the induced voltage at both ends of the cable is likely to be too large. When the distance of power supply is long, the middle joint of the cable will inevitably appea...
