It is ropy distribution transforming), distribution loss sharply increases, and causes resonance, produces harmonic wave, influences other electrical equipments.
(2) to the influence of electrical equipment：Overtension can significantly shorten the most electrical equipment life-span, and cause to be lost
Increase.Such as voltage rise 10%, the service life life-span of incandescent lamp reduces about 70%.
3rd, reactive-load compensation effect is poor：The long-term Smaller load operation in power distribution station, the minimum differential electric capacity 10 of conventional compensation device~
20kvar can not be put into, and compensation device utilization rate is low, and compensation effect is poor.(20kvar differential years cause active loss about
16000kW·h)。
4th, taiwan area protection is unreliable：Power distribution station routinely uses fast tripping protection of the fuse switch as taiwan area, low pressure
Side breaker of plastic casing carries out excessively stream and fast tripping protection to customer charge.It is larger that breaker of plastic casing typically configures rated current, loses
Overload protection ability, overload often result in distribution transforming and burnt；And taiwan area or low-voltage load failure are because of the unreliable Chang Yue of fast tripping protection
Level tripping operation causes whole piece circuit large-area power-cuts.
5th, installation is inconvenient：Conventional electrical distribution taiwan area is typically by transformer, transformer theft-proof terminal box, distribution box, ammeter box
Composition.Component is more, and cabling is mixed and disorderly, and installs complicated.
6th, automaticity is low：The complete manually execute-in-place of spatial load forecasting, how not wide power distribution station distributed point is, possesses and matches somebody with somebody
Electric automation basis, also lack effective management service without its running status of unified background monitoring, operation.This pair with rural power grids
The higher and higher demand of the management of power use is incompatible.
