Embodiment Construction
[0010] According to the accompanying drawings, the present invention is a DC cable terminal oil-gas interface lifting device, which is applied to DC cable terminals and can also be applied to UHV AC cable terminals, including cable 1, cable core 2, outlet rod 3, top cover 6, rain cover 4. Insulating bushing 12, insulating oil 13, bushing flange 11 and prefabricated oil tank 8. The prefabricated oil tank 8 has no bottom and no cover, one end of which is connected to the sleeve flange 11 by the second tightening bolt 10, and the other end is connected to the top cover 6 by the first tightening bolt 7, and is connected to the DC cable terminal through the insulating sleeve 12 Insulating oil 13 is poured into the cavity to lift the insulating oil interface upward until the interface height of the insulating oil 13 is raised to more than half of the height of the prefabricated oil tank 8, and the interface height of the insulating oil 13 exceeds the horizontal plane of the casing fl...
