Abstract: The present disclosure provides a grounding structure, a method for assembling the same and a gas-insulated transmission line. The grounding structure includes a grounding guide defining a guiding hole and a grounding support fixed on the grounding guide and defining a cavity for accommodating a grounding contact. The grounding contact is arranged in the cavity and protrudes through the guiding hole on the grounding guide. The grounding contact is moveable along the wall of the cavity by a grounding spring accommodated in the cavity to realize the adaptive adjustment of the installation position. The grounding structure can be pre-assembled in an accurate and efficient way to avoid the components therein damaging, thereby improving the reliability and safety of the grounding structure and the gas-insulated equipment in which the grounding structure is used.

Abstract: Embodiments of the present disclosure provide an insulation supporting assembly. The insulation supporting assembly includes an insulator and at least one connecting plate. The insulator includes a central portion and at least one supporting leg. The central portion includes a through hole extending along a central axis and adapted to receive an inner conductor of a gas-insulated transmission line. The supporting leg extends outwardly from the central portion in a radial direction normal to the central axis. Each of the connecting plates is arranged at an end of a respective supporting leg and includes at least one first hole for mounting the respective connecting plate to an outer enclosure of the gas-insulated transmission line by a first threaded fastener. Embodiments of the present disclosure provide a gas-insulated transmission line including the above-mentioned insulation supporting assembly as well.
