Afterwards, the four insulating pads 2 are pushed into the gaps between the four insulating support plates 6 to further support the coil 3, so that the four insulating support plates 6 support the coil 3 first, thereby reducing the difficulty of installing the four insulating pads 2 and improving the work efficiency of the staff.

[0041] A method for using a coil support device for a 10KV voltage transformer:

[0042] S1 picks up the support rod 1, aligns it with the coil 3 for the 10KV voltage transformer in the installation slot, pushes the support rod 1 between the coils 3, and after pushing it in, pulls the limit plate 20 out of the limit slot 4;

[0043] S2 uses a wrench to clamp the limit plate 20, and then rotates the limit plate 20, so that the four moving rods 5 drive the four insulating support plates 6 away from the support rod 1 to support the coil 3;

[0044] S3 aligns the limiting plate 20 with the limiting groove 4, loosens the limiting plate 20, and pushes the limiting plate 20 into the limiting groove 4 together with the spring 18 to limit and fix the limiting groove 4;

[0045] S4 pushes the four insulating spacers 2 into the gaps between the four insulating support plates 6 to provide further insulating support for the coil 3 for the 10KV voltage transformer in the mounting slot.

[0046] Furthermore, the pulled-out limit plate 20 is clamped and rotated by a wrench, which saves effort when rotating the limit plate 20. The limit plate 20 is then aligned with the limit slot 4, and the limit plate 20 is pushed into the inside of the limit slot 4 with the spring 18 to limit and fix the limit slot 4, thereby reducing the difficulty of the four insulating support plates 6 in supporting the coil 3 and improving the work efficiency of the staff.

[0047] Working principle: When using this device, push the support rod 1 into the interior of the coil 3, then pull the limit plate 20 out of the interior of the limit groove 4, the limit plate 20 drives the convex cylinder 17 fixedly connected thereto to move, so that the convex cylinder 17 drives the rectangular plate 22 fixedly connected thereto to move upward inside the rectangular groove 21, and makes the annular connecting plate 19 connected to the lower end of the convex cylinder 17 rotate upward, driving the spring 18 fixedly connected to the annular connecting plate 19 to stretch, when the limit plate 20 leaves the interior of the limit groove 4, the limit plate 20 can be rotated with a wrench, the limit The positioning plate 20 drives the convex cylinder 17 to rotate, and the rectangular plate 22 at the lower end of the convex cylinder 17 rotates synchronously with the rotation of the convex cylinder 17, so that the round rod 15 on the outer surface of the rectangular plate 22 rotates, and the two first bevel gears 11 fixedly connected to the round rod 15 rotate, and the first bevel gear 11 on the upper side drives the two second bevel gears 13 meshing with it to rotate, and the two second bevel gears 13 rotate to drive the two first connecting rods 9 fixedly connected to it to rotate, and the two first connecting rods 9 rotate to drive the two fixedly connected threaded rods 8 to rotate. When the first bevel gear 11 on the lower side rotates, it drives the second bevel gear 13 meshing with it to rotate, thereby driving the second connecting rod 12 fixedly connected to it to rotate, and the two threaded rods 8 fixedly connected at both ends of the second connecting rod 12 also rotate with the rotation of the second connecting rod 12. The two first connecting rods 9 and the second connecting rod 12 rotate to drive the four threaded rods 8 to rotate, and the four threaded rods 8 rotate to drive the four corresponding moving rods 5 to move. The four moving rods 5 move in the corresponding sliding grooves 7 in the direction away from the support rod 1, so that the four The corresponding insulating support plates 6 on the moving rods 5 are away from the support rods 1, so that the four insulating support plates 6 support the coil. After the support is completed, the limit plate 20 is made to correspond to the limit groove 4, loosened, and then the limit plate 20 is pushed back into the limit groove 4. At the same time, the spring 18 drives the annular connecting plate 19 to pull the limit plate 20 back into the limit groove 4, fix the limit plate 20, and thus fix the positions of the four insulating support plates 6. At this time, the insulating pad 2 can be pushed in along the gap between the four insulating support plates 6 to insulate the support rod 1 and the coil 3.
