Internal anti-theft fixing structure of transformer insulator

The invention discloses an internal anti-theft fixing structure of a transformer insulator in the transformer insulator anti-theft field. The internal anti-theft fixing structure comprises a top plate of a cabinet body and an insulator of which the lower end is inserted into the top plate, a plurality of jacks are formed in the top plate, and the insulator is fixed on the top plate through a fixing structure. The fixing structure comprises a clamping block which passes through the jack and is used for fixing the insulator, and an anti-falling mechanism which is arranged below the top plate and is used for fixing the clamping block. The anti-falling mechanism is located on the lower portion of the top plate, the insulator cannot be fixed from the outside of the box body, the anti-theft performance is good, and the insulator is not prone to being lost. 本发明公开了变压器绝缘子防盗领域的一种变压器绝缘子内部防盗固定结构，包括柜体的顶板和下端插在顶板内的绝缘子，顶板开设有多个插孔，绝缘子通过固定结构固定在顶板上，固定结构包括穿过插孔并用于固定绝缘子的卡块和设有顶板下方用于固定卡块的防脱机构；防脱机构位于顶板下部，从箱体外部无法解除对绝缘子的固定，防盗性较好，不易丢失。
