The invention relates to a pipeline bus and a bus unit of the pipeline bus. The bus unit of the pipeline bus comprises a tube body, a conductive rod and insulators. The insulators comprise a fixed supporting insulator and a movable supporting insulator. The fixed supporting insulator is provided with a conductive insert. One side of the conductive insert is provided with a fixation structure and the other side is provided with an insert structure. The movable supporting insulator is provided with a conductive rod passing hole. The overall length of the conductive rod is smaller than the lengthof the tube body. One end, close to the fixed supporting insulator, of the conductive rod is provided with a detachable section, and the end, away from the fixed supporting insulator, of the conductive rod extends out of the bus unit. The length of the detachable section is larger than the insert fit length of the conductive rod and the conductive insert. One can detach one section of but unit from the whole pipeline bus only by detaching the detachable section, so that detaching can be realized more conveniently, detaching efficiency is greatly improved, and maintenance cost is reduced.
Description
technical field [0001] The invention relates to a pipeline busbar and a busbar unit of the pipeline busbar. Background technique [0002] Gas-insulated metal-enclosed transmission lines (GIL) have large transmission energy, low power loss, and high reliability. They are widely used in AC transmission under special circumstances and become the first choice to replace overhead transmission lines. GIL generally requires long-term operation and high safety. For high-voltage GIL, if its insulating components fail, it may cause regional power outages and cause major economic losses. Therefore, the reliability of high-voltage GIL is higher, and special equipment must be used insulating parts. [0003] At present, the insulating components for high-voltage GIL mainly include pot insulators and three-pillar insulators. The pot insulators can only be used to support high-voltage conductors, and cannot realize sliding support, that is, they cannot adapt to the length change of high-vo...
