[0002] Partial discharge signals refer to weak discharge signals generated in power equipment and are one of the precursor signals of power system failure. The spectrum and amplitude of partial discharge signals contain important information about the status and health of the equipment. When a partial discharge defect exists in the cable, the high-frequency pulse current of the partial discharge will propagate along the cable core and flow into the high-voltage circuit of the switch cabinet.

The present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present invention.

[0021] Example 1

[0022] like Figures 1 to 5 As shown, a cable partial discharge signal detection device based on an enclosed distribution switch cabinet includes a reeling mechanism 1, a releasing mechanism 2, an arranging mechanism 3, a transmission mechanism 4, and a clamping mechanism 5. The releasing mechanism 2 is mounted on the reeling mechanism 1, the arranging mechanism 3 is mounted inside the reeling mechanism 1, the transmission mechanism 4 is mounted inside the reeling mechanism 1, and the clamping mechanism 5 is mounted at the rear end of the reeling mechanism 1.

[0023] The winding mechanism 1 is used for winding, the releasing mechanism 2 is used to release the winding mechanism 1, the arranging mechanism 3 is used for arranging, the transmission mechanism 4 is used for transmission, and the clamping mechanism 5 is used for clamping;

[0024] The winding mechanism 1 includes a winding bin 11, a winding roller 12 and a worm spring 13. The winding roller 12 is rotatably mounted in the winding bin 11 via the worm spring 13.

[0025] The release mechanism 2 includes a button 21, a spring 22, and two sets of ratchet rings 23. The button 21 is slidably mounted on the winding bin 11 via the spring 22. The two sets of ratchet rings 23 are mounted on the winding roller 12 and the button 21 respectively.

[0026] The arrangement mechanism 3 includes a reciprocating screw 31, a threaded block 32, and a limiting ring 33. The reciprocating screw 31 is rotatably mounted in the winding bin 11, and the threaded block 32 is slidably mounted in the winding bin 11. The threaded block 32 is threadedly engaged with the reciprocating screw 31, and the limiting ring 33 is mounted on the threaded block 32.

[0027] The transmission mechanism 4 includes a driving bevel gear 41, a driven bevel gear 42 and a bevel gear shaft 43. The driving bevel gear 41 is mounted on the winding roller 12, the driven bevel gear 42 is mounted on the reciprocating screw 31, and the bevel gear shaft 43 is rotatably mounted in the winding bin 11. The driving bevel gear 41 and the driven bevel gear 42 are both meshed with the bevel gear shaft 43.

[0028] The clamping mechanism 5 includes a limit frame 51, a clamping block 52 and a screw 53. The limit frame 51 is installed at the rear end of the winding bin 11, the clamping block 52 is slidably installed in the limit frame 51, and the screw 53 is rotatably installed on the limit frame 51, and the screw 53 and the clamping block 52 are threadedly engaged.

[0029] The clamping block 52 is moved by rotating the screw 53 and threading it with the clamping block 52. The clamping block 52 moves and cooperates with the limit frame 51 to clamp the connecting line. The two sets of ratchet rings 23 are embedded to stop the winding roller 12 from rotating freely. The ratchet ring 23 is released by pressing the button 21, and the winding roller 12 is driven by the worm spring 13 to rotate the winding roller 12, so that the winding roller 12 rewinds the connecting line. At the same time, the driving bevel gear 41 rotates by the rotation of the winding roller 12, and the driving bevel gear 41 rotates with the bevel gear 41. The engagement of the wheel axle 43 causes the bevel gear shaft 43 to rotate. While the bevel gear shaft 43 rotates, it engages with the driven bevel gear 42, causing the driven bevel gear 42 to drive the reciprocating screw 31 to rotate. The reciprocating screw 31 rotates and is threadedly matched with the threaded block 32 to cause the threaded block 32 to reciprocate.

By pressing the button 21 to release the ratchet ring 23, the winding roller 12 is driven by the worm spring 13 to rotate the winding roller 12, thereby making the winding roller 12 rotate. The winding roller 12 reels the connecting line, and the driving bevel gear 41 rotates by rotating the winding roller 12. When the driving bevel gear 41 rotates, it engages with the bevel gear shaft 43 to rotate the bevel gear shaft 43. When the bevel gear shaft 43 rotates, it engages with the driven bevel gear 42 to drive the driven bevel gear 42 to drive the reciprocating screw 31 to rotate. The reciprocating screw 31 rotates and is threadedly matched with the thread block 32 to make the thread block 32 reciprocate. At the same time, the connecting line is limited and arranged by the limiting ring 33.
