Description
Technical field
It is more specifically that a kind of adjacent phase conductor of 500kV transmission lines of electricity is changed the present invention relates to power system field of power transmission
Phase structure.
Background technology
ABC three-phases in transmission line of electricity are typically parallel arranged, and the transformer station at two ends is connected.But it is sometimes necessary
Phase sequence to a certain section is adjusted so that the wire positioned at middle phase transforms to side phase originally, and the wire positioned at side phase becomes originally
Middle phase or the side phase of opposite 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, is all converted three-phase conducting wire once in putting in order for space using transposition tower, eliminates 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 situations are that transmission line of electricity two ends only have two-phase phase sequence and do not corresponded at present, only carry out commutation with to two-phase, no
Need three-phase all transpositions.During transmission line of electricity " π connects " enters transformer station, it often happens that.In many " π
Connect " in engineering, often occur that transmission line of electricity phase sequence only has that two-phase is not corresponding with transformer station outlet phase sequence, former circuit connects by π
After transformation, the phase adjustment of all fronts is typically no longer carried out, many times needs to carry out commutation to adjacent phase conductor on transposition tower.
At present, 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 replaced mutually between side phase and middle phase, how to realize and replace mutually between adjacent phase, urgent need to resolve.
