[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] A wireless distributed waveform recording device, such as Figures 1-5 As shown, the waveform recording device is distributed on the cable and is used to monitor the current on the cable to prevent faults in the UHV project. The waveform recording device includes a first housing 1, a second housing 2 rotatably mounted on the first housing 1, a circular groove between the first housing 1 and the second housing 2, and a cable clamp 3 fixedly installed in the circular groove. The cable clamp is fitted onto the outside of the UHV cable to monitor the UHV cable.

[0027] A bearing seat 11 is fixedly provided on the first outer shell 1. The bearing seat 11 is rotatably connected to the second outer shell 2. A connecting seat 12 is fixedly provided on the first outer shell 1. The connecting seat 12 and the bearing seat 11 are located on both sides of the circular groove. The circular groove is composed of two half-grooves 16. The two half-grooves 16 are located on the first outer shell 1 and the second outer shell 2 respectively. A locking groove 17 is provided in the half-grooves 16. A slope 13 is provided on one side of the connecting seat 12 and a groove 14 is provided on the other side.

[0028] The second outer shell 2 has a cross groove 21. Two parallel limiting pins are fixed in the cross groove 21. A locking rod 15 is slidably provided on one side of the limiting pin. The limiting pin limits both ends of the locking rod 15 to prevent the locking rod 15 from sliding out of the cross groove 21. The connecting seat 12 slides into the cross groove 21 from one side of the second outer shell 2. The locking rod 15 slides against the inclined surface 13 until the connecting seat 12 enters the depth of the cross groove 21. At this time, the locking rod 15 falls above the limiting pin and is located in the groove 14. At this time, the locking rod 15 is fixed to the connecting seat 12 without external force. After the bolt passes through the locking rod 15, it is threadedly connected to the connecting seat 12, thus connecting and fixing the first outer shell 1 and the second outer shell 2.

[0029] A limiting block 31 is fixedly provided on the outer ring of the cable clamp 3. Claws 33 are fixedly provided at both ends of the cable clamp 3. The two claws 33 face each other and are staggered. A groove 32 is provided on one side of each claw 33. When the ends of the two cable clamps 3 are fitted together, the claws 33 extend into the groove 32 at the end of the other cable clamp 3 for connection. At this time, the two cable clamps 3 are horizontally staggered. Then, one cable clamp 3 is pushed, causing the claws 33 to slide horizontally into the depth of the groove 32, making the end faces of the two cable clamps 3 flush (e.g., ...). Figure 2 As shown in the figure, complete the connection and fixation of the three pairs of high-voltage cables in the cable clamp.

[0030] The limiting block 31 is connected to the locking groove 17 to fix the cable clamp 3. At this time, the cable clamp 3 is fixed to the cable. Then, the cable clamp 3 is installed between the first outer shell 1 and the second outer shell 2. When the second outer shell 2 is fastened, the locking rod 15 slides into the groove 14 to limit the first outer shell 1 and the second outer shell 2. The installer does not need to hold the outer shell. He can take the screw or bolt and thread it through the locking rod 15 and connect it to the connecting seat 12. The waveform recording device is then fixed and assembled. The current transformer in the waveform recording device is used to monitor the current of the cable, thereby monitoring the operating status of the UHV key equipment.
