Embodiment Construction

[0050] The specific implementation of the pipeline busbar and its busbar unit in the present invention will now be described in conjunction with the accompanying drawings.

[0051] Such as figure 1 As shown, it is an embodiment of the pipeline busbar in the present invention: the pipeline busbar is connected by a busbar unit. Rod insulators. There are two adjacent first busbar units 20 and second busbar units 10 in the pipeline busbar, and its structure includes a first cylinder body 21 and a second cylinder body 11 connected by flanges. Such as figure 2 As shown, the junction of the first cylinder 21 and the second cylinder 11, that is, between the first cylinder flange 212 and the second cylinder flange 111, is provided with a basin-type insulator 23 belonging to the first busbar unit 20, the basin One side of the type insulator 23 stops and cooperates with the flange 211 provided in the first cylinder 21, and the other side stops and cooperates with the stopper 25 sandw...

Abstract

The invention relates to the technical field of GIL and provides a bus unit and a pipeline bus. The bus unit comprises a bus cylinder and a conducting rod, wherein one end of the bus cylinder is provided with a fixed insulator which is fixedly arranged relative to the bus cylinder, two axial ends of the fixed insulator are provided with a fixed connecting seat and a plug-in connecting seat respectively, the fixed connecting seat is used for fixing and conductively connecting the corresponding conducting rod in the bus unit or in the adjacent bus unit, and the plug-in connecting seat is used for plug-in matching and conductively connecting the corresponding conducting rod in the bus unit or in the adjacent bus unit. The fixed connecting seat and the plug-in connecting seat arranged on the two sides of the insulator in the bus unit change a conductive rod in the prior art into a mode that one end is fixed and the other end is telescopic, the telescopic movement of only one end of the conductive rod is limited, and the whole conductive rod can still adapt to temperature change through self telescopic deformation; a problem that the insertion length of the conducting rod is too short and even falls off when the conducting rod expands with heat and contracts with cold can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of GIL, in particular to a busbar unit and a pipeline busbar. Background technique [0002] GIL has the advantages of high reliability, strong transmission capacity, low loss, safety and environmental protection, and convenient installation, operation and maintenance, etc., and has been widely used in power engineering. GIL is a cylinder-enclosed power transmission equipment composed of a cylinder and conductive rods. The GIL bus section generally includes multiple bus units, so the laying line is relatively long. Since the application length of GIL equipment may reach tens of kilometers, the conductive rod will generate heat to heat up the GIL due to the passage of current. When the temperature changes, the cylinder and the conductive rod will expand and contract correspondingly. Thermal expansion and contraction produce relative displacement in the axial direction, which affects the connection between the...
