Connection structure between transmission line and wall bushing

Abstract

The invention relates to the technical field of high voltage transmission, in particular provides a connection structure of a transmission line and a wall bushing, the connection structure includes alead-out wire for connection with a transmission line, The lead-out wire is connected with the wall bushing through the pipe bus, and an insulating adapter for realizing the conduction between the lead-out wire and the pipe bus is arranged between the lead-out wire and the pipe bus, and the insulating adapter is relatively fixed with the wall bushing, and the insulating adapter is provided with apipe bus end connected with the pipe bus and a lead-out wire end connected with the lead-out wire respectively. The insulation adapter is relatively fixed with the wall bushing, and the insulation adapter supports the mother pipe, so that the mother pipe is not directly connected with the lead-out wire, the external force transmitted from the lead-out wire to the mother pipe is transmitted to theinsulation adapter, and the mother pipe is not swayed by the external force because the insulation adapter supports the mother.pipe The connection structure reduces the damage of external force to themother pipe and wall bushing, and reduces the influence of external force on the wiring between the power network and the converter station.

Description

technical field [0001] The invention relates to the technical field of high-voltage power transmission, in particular to a connection structure between a power transmission line and a wall bushing. Background technique [0002] The converter station refers to the station in the UHV DC transmission system in order to complete the conversion of direct current to alternating current or convert alternating current to direct current. In the outgoing line of the pole line of the ultra-high voltage converter station, the outgoing line tower is usually used to directly connect the down wire to the However, when the wires are subjected to external forces such as wind or earthquakes, the wires will swing on the transmission line and damage the connection structure of the wires. On the one hand, it will cause flashover burns on the wires, and even lead to breakage ; On the other hand, the swing of the wire will drive the action of the wall bushing, thereby causing damage to the wall bu...
