Among them, the second fastener 4 is selected as a bolt, and internal threads are provided in both the first connection hole 31 and the second connection hole 11, so that the second fastener 4 can be threadedly connected to the first connection hole 31 and the second connection hole 11; when the connection cables need to be used and taken out, loosen the second fastener 4, so that the protective box 3 can slide relative to the detector body 1. By pressing the protective box 3, the protective box 3 can be made to slide, so that a plurality of cable winding assemblies 2 can pass through the through holes 32 and be exposed. Furthermore, by loosening the first fastener 243, the connection cables can be conveniently taken off from the winding column 21 for use; similarly, when the connection cables are used up and wound on the winding column 21, by sliding the protective box 3 outwards, a plurality of cable winding assemblies 2 can be shielded, and by tightening the second fastener 4, the protective box 3 can be fixed on the outer side of the detector body 1 to realize the shielding and protection of the connection cables and the cable winding assembly 2, and avoid accidentally knocking the cable winding assembly 2 during carrying and transportation.

[0026] The working principle of a substation fault testing device provided in an embodiment of the present application is as follows:

[0027] When it is necessary to carry the connecting cable, first loosen the second fastener 4 so that the protective box 3 can slide relative to the detector body 1. Then, by pressing the protective box 3, the protective box 3 can slide along the outside of the detector body 1, so that a plurality of cable winding components 2 pass through the through hole 32 and are exposed. Then, first insert one end of the connecting cable into the arc-shaped ring 241 provided on the first fixing block 22, and then fasten the first fastener 243 provided on the arc-shaped ring 241, so as to fix one end of the connecting cable in the arc-shaped ring 241. Then start to gradually wind the connecting cable around the outside of the winding column 21 until the end of the wound connecting cable reaches the position of the arc-shaped ring 241 of the second fixing block 23. Then insert the end of the wound connecting cable into the inside of the arc-shaped ring 241 on the second fixing block 23, and at the same time fasten the first fastener 243 on the arc-shaped ring 241, so as to fix the wound end of the connecting cable inside the arc-shaped ring 241 on the second fixing block 23. Among them, during the process of winding the connecting cable, if the wound end of the connecting cable just cannot reach the arc-shaped ring 241 on the second fixing block 23, the second fixing block 23 can be rotated so that the second fixing block 23 and the arc-shaped ring 241 on the second fixing block 23 rotate a certain angle relative to the winding column 21, so that the wound end of the connecting cable can reach the arc-shaped ring 241 on the second fixing block 23, so that the wound end of the connecting cable can be conveniently inserted into the arc-shaped ring 241 on the second fixing block 23, which is convenient for fixing the wound end of the connecting cable later. The remaining connecting cables are wound around the remaining winding columns 21 in the same way as above. After all the connecting cables are wound and fixed, slide the protective box 3 outwards so that all the cable winding components 2 enter the inside of the protective box 3 through the through hole 32, realizing the shielding and protection of the cable winding components 2 and the connecting cable. Finally, fasten the second fastener 4 so that the second fastener 4 passes through the first connection hole 31 and the second connection hole 11 to realize the fixation of the protective box 3.
