Three-phase linkage rotating bus device

Abstract

The invention discloses a three-phase linkage rotation bus apparatus. The apparatus comprises two sets of bus systems which are erected between two bus support apparatuses in parallel. The two sets of bus systems comprise a main bus and a standby bus. The three-phase linkage rotation bus apparatus also comprises at least three sets of rotation apparatuses used for realizing three-phase linkage switching of the main bus and the standby bus and a rotating shaft. Each set of the rotation apparatuses comprises three pillars located in a same rotation plane. Two ends of each pillar are connected to pillar insulators respectively. Three-phase wirings of the main bus and the standby bus are erected on terminal heads of the pillar insulators of corresponding phases in parallel respectively. The three pillars are concentric and the two of the pillars are intersected. An intersection center is located at a center of a circle of a same rotation circle. The rotating shaft passes through the intersection center of each pillar. Two ends of the rotating shaft are hinged to the bus support apparatuses of corresponding sides respectively. By using the apparatus of the invention, an erection land occupation area of a transformer substation is greatly saved.

Description

Technical field [0001] The invention relates to a substation bus erection device, in particular to a three-phase linkage rotating bus device. Background technique [0002] During the commissioning of the existing substation, when a certain section of the main bus has an operating failure, it needs to be overhauled. At this time, the conversion between the two is often achieved through two sets of isolation switches arranged between the main bus and the backup bus. [0003] However, if the three-phase busbar needs to be overhauled, the switching of each section of the main busbar needs to be realized by the switching of the respective isolation switches. Therefore, this existing switching method of the isolation switch becomes very troublesome. [0004] Moreover, since there is an isolating switch between the main bus of each phase and its backup bus, it will inevitably occupy a large area when the substation is erected during installation. [0005] Therefore, it is necessary for thos...

AI Technical Summary

Problems solved by technology

[0003] However, if the three-phase bus needs to be overhauled, since the switch of each section of the main bus needs to be realized by switching the isolating switch equipped respectively, the switching method of this existing isolating switch is very cumbersome.

[0004] Moreover, since there is an isolating switch between the main busbar of each phase and its standby busbar, the floor area of ​​the substation will be greatly occupied during installation.
