Preferably, the insulator string 6 is a composite insulator string. The suspension device 5 suspends the analog conducting wire 3 so as to make the analog conducting wire 3 have a preset distance from the ground, and in the specific implementation, the preset distance can be determined according to the actual situation, and the embodiment does not limit the distance. In a specific implementation, the suspension device 5 may be a traveling crane, and of course, may be another suspension device as long as it can suspend the analog conductor 3, and this embodiment does not limit this. The simulation lead 3 is an eight-split or six-split simulation test lead special for extra-high voltage, and the simulation lead 3 is an eight-split or six-split simulation lead manufactured according to the split radius size of an actual extra-high voltage line.
The voltage generator 4 is connected to the analog conductor 3, and the voltage generator 4 is configured to apply a predetermined voltage to the analog conductor 3. Specifically, the voltage generator 4 is connected to the analog conductor 3 through a metal lead 12, and the voltage generator 4 may output an ac 1000kV or a dc ± 800kV voltage to charge the analog conductor 3. In specific implementation, the preset voltage may be a voltage applied to a wire of the power transmission line in an actual situation, and may be determined according to the actual situation, which is not limited in this embodiment. The voltage generator 4 may be an extra-high voltage ac test transformer, an extra-high voltage dc voltage generator, or another voltage generator, which is not limited in this embodiment.
The dummy wire 3 and the supporting platform 110 have a predetermined distance in the horizontal direction (a direction shown in fig. 1), and specifically, the dummy wire 3 and the edge of the supporting platform 110 facing the dummy wire 3 (right side shown in fig. 1) have a predetermined distance in the horizontal direction, and the predetermined distance is used for preventing the arc discharge between the live dummy wire 3 and the insulating support device 1, so as to avoid the risk of the arc discharge to the trainee standing on the supporting platform 110 before the potential transfer operation is started. In specific implementation, the preset distance may be determined according to actual conditions, as long as the trainee can avoid being influenced by the discharge of the charged simulation lead 3, which is not limited in this embodiment.
The supporting platform 110 is provided with a supporting body, the potential transfer rod 2 is movably arranged on the supporting body, and the potential transfer rod 2 is used for contacting with the analog lead 3. Specifically, a support is disposed at a position of the carrying platform 110 close to the simulation lead 3, the potential transfer rod 2 is disposed on the support, and the potential transfer rod 2 can move along a preset path toward the simulation lead 3 on the support under the pushing action of the trainee. In specific implementation, the preset path may be a linear motion of the potential transfer rod 2, and of course, other paths may also be used, which is not limited in this embodiment. The top surface of simulation wire 3 and supporter is located the coplanar, like this, just can contact with electrified simulation wire 3 when the electric potential shifts stick 2 to simulation wire 3 rectilinear movement for thereby the student equals with electrified simulation wire 3's electric potential and accomplishes the electric potential and shifts.

In specific implementation, in order to make the electric potential transfer rod contact with the analog conducting wire 3 along the linear motion, the preset distance between the analog conducting wire 3 and the ground corresponds to the height of the supporting body on the bearing platform 110.
If the student stands on the bearing platform 110, the student directly holds the potential transfer stick 2 to contact with the electrified simulation lead 3, and because the habits of the students are different, the path and angle of the contact between the potential transfer stick 2 held by the student and the electrified simulation lead 3 are not easy to control, so that the electrified simulation lead 3 is easy to discharge to the hands of the student, and the danger is easily caused to the student. Therefore, the potential transfer rod 2 moves towards the analog lead 3 along the preset path, so that the moving paths of the potential transfer rod 2 are uniform, and the danger of the charged analog lead 3 discharging to students is avoided.
In a specific implementation, the length of the potential transfer rod 2 is preset, for example, the length of the potential transfer rod 2 is 0.8 m to 1.2 m, which can be selected according to actual situations, and the present embodiment does not limit this. In specific implementation, the preset distance between the analog conductor 3 and the edge of the supporting platform 110 facing to one side (the right side shown in fig. 1) of the analog conductor 3 is matched with the preset length of the potential transfer rod 2, so that the potential transfer rod 2 can be contacted with the analog conductor 3 after moving towards the analog conductor 3. If the preset distance between the simulation lead 3 and the edge of the bearing platform 110 facing to the simulation lead 3 is far longer than the preset length of the potential transfer rod 2, the insulation support device 1 needs to slide to the simulation lead 3 to a distance matched with the preset length of the potential transfer rod 2, so that the danger of the arc discharge generated by the simulation lead 3 to the trainee can be prevented, and the potential transfer rod 2 can be in contact with the simulation lead 3.
During practical training, the simulation lead 3 is hung on the hanging device 5 through the insulator string 6, and the distance between the insulation supporting device 1 and the simulation lead 3 in the horizontal direction is adjusted. The students wear a whole set of extra-high voltage live working shielding clothes and climb to the bearing platform 110 along the insulation steps on the insulation supporting device 1. Because the student is not convenient for the student to hand the electric potential transfer stick 2 when climbing insulating support device 1, so, after the student climbed to load-bearing platform 110, subaerial staff can transmit electric potential transfer stick 2 for the student. The ground worker starts the voltage generator 4, and the voltage generator 4 outputs a preset voltage, so that the analog lead 3 is electrified. The student places the potential transfer stick 2 on the support body, pushes the potential transfer stick 2, and then the potential transfer stick 2 can move linearly towards the direction of the analog lead 3 until the potential transfer stick 2 contacts with the analog lead 3, and the potential transfer is completed. Then, the trainee gives an instruction of success of the potential transition to the worker, and the worker controls the insulation support device 1 to slide to the analog lead 3 (to the right as shown in fig. 1) according to the instruction until the trainee can directly contact the charged analog lead 3 with a hand, so that the trainee performs the subsequent training project.
