The voltage dividing column 9 is provided with a connecting terminal 14. The V-shaped reinforcing plate 15 is arranged on the isolation column support frame 7.

[0031] The working principle of the transformer insulation support structure: during the operation of the transformer, the current enters the insulating sleeve 4 through the first voltage transmission line 5. The insulating sleeve 4 plays a protective and insulating role to prevent current leakage. After the current passes through the insulating sleeve 4, it enters the insulating isolation column 6 connected with the insulating sleeve 4.

[0032] The isolation column support frame 7 below the insulating isolation column 6 plays a role in supporting and fixing the insulating isolation column 6, and the V-shaped reinforcing plate 15 on the isolation column support frame 7 enhances the stability of the structure.

[0033] The current is conducted from the insulating isolation column 6 to the voltage dividing column 9 through the second voltage transmission line 8. The connecting terminal 14 on the voltage dividing column 9 is used for connecting and distributing the current. The insulating conical frame 10 below the voltage dividing column 9 helps to disperse pressure and maintain the stability of the structure.

[0034] After passing through the insulating conical frame 10, the current is conducted to the insulating buffer plate 11. The insulating buffer plate 11 plays a role in buffering and shock absorption, reducing vibration and impact during current transmission.

The insulating support block 13 below the insulating space frame 12 provides a solid support for the entire structure.

[0036] Through the synergistic effect of the above components, the transformer insulation support structure can effectively realize the transmission and insulation protection of the current, ensuring the normal operation of the transformer.

After receiving the current, the lower isolation column support frame 7 provides stable support for the isolation column 6, and the V-shaped reinforcing plate 15 on the isolation column support frame 7 enhances the stability of the support. The current is conducted from the insulating isolation column 6 to the voltage dividing column 9 through the second voltage transmission line 8, and the connecting terminal 14 on the voltage dividing column 9 distributes the current.

The insulating space frame 12 prevents abnormal conduction of the current and ensures that the current is transmitted along the predetermined path. Finally, the current is conducted to the insulating support block 13 below the insulating space frame 12, which provides a solid bottom support for the entire structure.
