Through this monitoring, abnormal situations can be discovered and processed in time, the occurrence of cable faults can be avoided, and the safe, stable and reliable operation of the power system, as well as the safety of people's lives and property, can be guaranteed.

[0003] When monitoring the operation state of the cable, a monitoring device needs to be used, and the monitoring device is usually installed below the outdoor high-voltage cable. Therefore, it needs to have excellent waterproof performance. When the existing monitoring device is in use, its wire usually exits from below the electric box, and there are easily some gaps between the wire and the electric box, which will cause water vapor to enter the electric box, affecting the service life of the internal components of the electric box. For this reason, a miniaturized high-voltage cable operation state monitoring device for multimode communication is proposed. Content of the Utility Model

[0008] As a further scheme of the utility model, fireproof mud is filled in the bottom cylinder.

[0009] As a further solution of the present utility model, clamping wire assemblies are provided at the bottoms of the bottom cylinders. Each clamping wire assembly includes a continuously bent wire conduit, both sides of the wire conduit are open, a threaded rod passing through is threadedly connected to the top of the wire conduit, and a clamping piece is rotatably connected to the bottom of the threaded rod.

[0010] As a further solution of the present utility model, a rubber pad is sleeved on the circumferential outer wall of the through cylinder.

After connection, the threaded cylinder is tightened. The threaded cylinder presses down the pressing ring through the pressing ring, and the pressing ring squeezes the silica gel ring, causing the silica gel ring to deform, thereby sealing the wire and preventing water vapor or other foreign objects from entering the box body. Then the threaded rod is rotated, and the threaded rod drives the clamping piece to clamp and fix the wire, improving the stability of the wire and preventing the wire from moving. When the wire is fixed, a part of the wire under the bottom cylinder can be pulled out and reserved, keeping the wire under the bottom cylinder in a relaxed state to avoid the wire being stressed.
