Tube bus fitting for converter station valve hall

Abstract

The invention discloses a tube bus fitting for a converter station valve hall, relating to the technical field of fittings and aiming to solve the problem that a conventional tube bus fitting can damage the equipment or disconnect from the equipment due to large stress under an earthquake working condition, and the basic electrical performance of the valve hall is lost. The tube bus fitting for the converter station valve hall comprises two first tube buses, one ends of the two first tube buses are used for being connected with two devices in a one-to-one correspondence mode, and the other ends of the two first tube buses are connected into a whole through a connecting unit, the connecting unit comprises a conductive structure, and one ends, close to the connecting unit, of the two first tube buses are connected with the conductive structure through wires, and the connecting unit is provided with a voltage equalizing piece used for a uniform electric field, and the connecting unit allows the two first tube buses to move in the height direction by deforming, so that the distance between the ends, connected with the devices, of the two first tube buses is changed. The fitting is usedfor realizing electrical connection, mechanical support and voltage-sharing shielding between the two devices in the converter station valve hall.

Description

Technical field [0001] The invention relates to the technical field of fittings, in particular to a pipe female fitting for a valve hall of a converter station. Background technique [0002] HVDC transmission has been widely used in my country because it can transmit a large amount of power energy with long distance, low loss and no drop point. As the core of the DC transmission project, the valve hall of the converter station is a place where AC and DC are mutually converted during the DC transmission process. Inside the valve hall are converter valves, wall bushings, converter valve side bushings, pillar insulators, lightning arresters, grounding switches and many other equipment. [0003] In the prior art, the electrical connection and voltage equalization shielding between the two devices are realized by the tube socket fittings, that is, the two connecting ends of the tube socket fittings in the prior art are used to connect two devices in a one-to-one correspondence.
