(1) each fault all can cause feeder line outlet switch trip.
(2) can not dwindle power supply interrupted district, non-faulty section also can cause power failure.
(3) isolated fault need feeder line go out wiretap repeatedly separating brake, close a floodgate to cooperate, cause non-fault zone repeatedly repeat have a power failure.
(4) the isolated fault required time is long, the combined floodgate segmentation on-load switch of need delaying time piecemeal.
For to extend the overhead feeder of radial pattern naturally, have many branch lines on the backbone, branch line extends many subbranch lines again, the line construction complexity, and the permanent each time or transient fault on the branch line can cause that all full bar feeder line has a power failure, coverage is bigger, and therefore traditional voltage feeder automation pattern can not satisfy the intelligentized development need of distribution.Therefore, this class switch has wide application prospect in electric power system.The normal employing of this class switching manipulation power supply needs external power source or adopts solar energy; if adopt current transformer CT power supply, the current transformer CT of use is that CT is used in protection, has so just influenced defencive function; cause incorrect switching easily, influence the safe operation of electric power system.Traditional vacuum switch power supply is generally provided by the power-supply system or the civil power of transformer station, for some remote circuit, must install power transformer additional and obtain power supply, the part switch adopts solar cell for supplying power, but solar cell is influenced by weather and air-polluting, the as easy as rolling off a log battery supply feed that causes influences the reliability of switching manipulation.
