Adjacent phase conductor commutation structure.
Background technology
ABC three-phases in transmission line of electricity are typically parallel arranged, and the substation at both ends is connected.But it is sometimes necessary
A certain section of phase sequence is adjusted so that the conducting wire for being located at middle phase originally transforms to side phase, and the conducting wire for being located at side phase originally becomes
Middle phase or the side phase of the other side are changed to, this is just referred to as transposition or commutation.Common transposition be by the position of ABC three-phases successively
Rotation, all transformation that puts in order using transposition tower by three-phase conducting wire in space are primary, eliminate unsymmetrical arrangement.This be common in because
Transmission line of electricity is long and in order to eliminate the influence of three-phase current asymmetrical voltage.
More situation is that transmission line of electricity both ends only have two-phase phase sequence and do not correspond at present, only carries out commutation with to two-phase, no
Three-phase is needed all to replace.During transmission line of electricity " π connects " enters substation, it often happens that.In many " π
Connect " in engineering, it often will appear transmission line of electricity phase sequence and only have that two-phase is not corresponding, and former circuit connects by π with substation outlet phase sequence
After transformation, the phase adjustment of all fronts is generally no longer carried out, many times needs to carry out commutation to adjacent phase conductor on transposition tower.
Currently, in engineering frequently with hanging transposition carry out in ABC three-phases while phase with while phase between commutation.But not yet
See the research report to replace mutually between side phase and middle phase, how to realize and replace mutually between adjacent phase, urgent need to resolve.
