[0060] In one embodiment, the test mechanism 300 is in conduction with the wire 400, when the conductive part of the test mechanism 300 is in conduction with the to-be-tested piece, the conduction between the wire 400 and the to-be-tested piece is realized, so as to realize the partial discharge test through the pulse.

[0061] As shown in Figure 1 and Figure 2 , the fixing sleeve 230 is provided with a first wire clamp 231, and the first wire clamp 231 is used for clamping the electric wire 400 to avoid inconvenience caused by random winding of the electric wire 400 and the like.

[0062] Optionally, as shown in Figure 1 and Figure 2 , the first wire clamp 231 is provided in plurality, and the plurality of first wire clamps 231 are arranged at intervals on the fixing sleeve 230.

[0063] In an embodiment, referring to Figure 7 , the test mechanism 300 comprises a mounting seat 310 and a conductive assembly, the mounting seat 310 is fixed at one end of the telescopic rod 220, and the conductive assembly is arranged on the mounting seat 310, and the conductive assembly is used for conductive cooperation with the to-be-tested piece to perform the partial discharge test.

[0064] The conductive assembly is in conductive cooperation with the to-be-tested piece to perform the partial discharge test.

[0065] The mounting seat 310 is not conductive with the conductive assembly, and the mounting seat 310 is made of insulating material, such as plastic and the like.

[0066] In an embodiment, referring to Figure 1 , Figure 2 , Figure 7 and Figure 8 , the test mechanism 300 further comprises a swing seat 320, a pull rope 330 and a first reset piece, the swing seat 320 is rotatably connected with the mounting seat 310, one end of the pull rope 330 is connected with the swing seat 320, and the first reset piece is used for resetting the swing seat 320 relative to the mounting seat 310.

[0067] As shown in Figure 8 , the conductive assembly comprises a first clamping seat 340, a second clamping seat 350 and a second reset piece, the first clamping seat 340 is arranged on the mounting seat 310, the second clamping seat 350 is rotatably connected with the first clamping seat 340, and the second clamping seat 350 is further rotatably connected with the swing seat 320, and the second reset piece is used for resetting the second clamping seat 350 relative to the first clamping seat 340.

[0068] Pulling the pull rope 330 can swing the swing seat 320 relative to the mounting seat 310, and when the swing seat 320 swings relative to the mounting seat 310, the second clamping seat 350 can be swung relative to the first clamping seat 340.

[0069] As shown in Figure 7 and Figure 8As shown, the first clamping seat 340 is disposed on the mounting seat 310, the second clamping seat 350 can rotate relative to the first clamping seat 340, and the second clamping seat 350 can also swing relative to it, while the swinging seat 320 can swing relative to the mounting seat 310.

[0070] like Figure 7 and Figure 8 As shown, in the initial state, the second clamping seat 350 does not rotate relative to the first clamping seat 340, and the swing seat 320 does not rotate relative to the mounting seat 310. When the test mechanism 300 reaches the vicinity of the test piece (e.g., a transformer), the pull rope 330 is pulled. At this time, the pull rope 330 causes the swing seat 320 to rotate relative to the mounting seat 310. Since the second clamping seat 350 is provided on the swing seat 320, when the swing seat 320 rotates relative to the mounting seat 310, on the one hand, the second clamping seat 350 rotates relative to the first clamping seat 340, and on the other hand, the second clamping seat 350 also rotates relative to the swing seat 320, thereby opening the second clamping seat 350 and the first clamping seat 340 to clamp the test piece, so that the test piece can contact and conduct with the conductive component. After the clamping is completed, the pull rope 330 is released. At this time, the first reset member resets the swing seat 320, and the second reset member resets the second clamping seat 350 to maintain the reliable clamping of the test piece by the first clamping seat 340 and the second clamping seat 350.

For example, both the first clamping seat 340 and the second clamping seat 350 may be conductive to achieve continuity through clamping. In this case, at least one of the first clamping seat 340 and the second clamping seat 350 may be conductive to the wire 400. Alternatively, the first clamping seat 340 may be conductive, while the second clamping seat 350 may not be conductive, but the wire 400 may be electrically connected to the first clamping seat 340. This way, after the test piece is clamped by the first clamping seat 340 and the second clamping seat 350, the test piece will inevitably come into contact with the first clamping seat 340, thus achieving continuity. Further details are omitted.

[0072] Optionally, both the first reset element and the second reset element are torsion springs.

[0077] As shown in Figure 7 , the connecting block 360 is provided with a first matching groove 361, which is generally an L-shaped groove. The matching shaft 351 is inserted into the first matching groove 361 so that the matching shaft 351 can rotate relative to the connecting block 360. In this way, the rotation of the second clamping seat 350 relative to the first clamping seat 340, the rotation of the second clamping seat 350 relative to the connecting block 360, and the rotation of the second clamping seat 350 relative to the swing seat 320 are realized.
