Problems solved by technology
If there is a fault in the middle of the cable, it often takes a lot of time to find the line fault because it cannot be located
At present, the direction of the cable and the specific position of the middle head of the cable are often recorded manually by humans, and automatic positioning cannot be realized.
In daily operation and maintenance, the state of the cable intermediate head cannot be effectively monitored
When troubleshooting cable lines, it takes a lot of manpower to locate the fault point, which seriously affects the progress of emergency repairs

The invention relates to the technical field of cables, and particularly relates to a monitoring device for a cable intermediate joint. The monitoring device comprises a mounting ring, a photoelectricenergy converter, a pulse transmitter, a first photoelectric signal converter and a sheath, wherein the mounting ring is arranged on the periphery of the cable intermediate joint in a sleeving mode;the photoelectric energy converter receives optical energy of an optical fiber and converts the optical energy into electric energy, and the photoelectric energy converter supplies power to the pulsetransmitter and the first photoelectric signal converter; the first photoelectric signal converter receives a pulse electric signal transmitted by the pulse transmitter, converts the pulse electric signal into a pulse optical signal, and transmits the pulse optical signal to a base station connected with the optical fiber through the optical fiber. The monitoring device provided by the invention for the cable intermediate joint can effectively overcome the technical defect that it is difficult to find and monitor the cable intermediate joint at present.
Description
technical field [0001] The present application relates to the technical field of cables, in particular to a monitoring device for a cable intermediate head. Background technique [0002] At present, 10kV cables and optical fibers are buried separately underground, and base stations connected to optical fibers are installed at certain distances. The weakest part of a section of cable is the cable middle end of this section of cable, which is the joint formed after the two ends of the cable are spliced. [0003] At present, there is no more effective means to find the middle head of the cable. If there is a fault at the middle head of the cable, it often takes a lot of time because it cannot be located when performing line fault finding. Currently, the direction of the cable and the specific position of the middle head of the cable are often manually recorded by humans, and automatic positioning cannot be realized. In daily operation and maintenance, the state of the cable ...
