Description
Technical Field
The utility model relates to a line conditioning equipment field, more specifically say, relate to a line voltage automatic regulator.
Background
Because rural power grid lines are long, the line loss is large, the load distribution is wide, the branch lines are more, and the electric load changes greatly along with day, night and seasons, the voltage quality of the whole line can be ensured by installing the line voltage automatic regulator at the middle end of the line; for a line with a heavier load, the voltage drop of the line is large due to the larger load, and the voltage quality of the whole line can also be improved by additionally arranging the line voltage automatic regulator at the middle end of the line.
SUMMERY OF THE UTILITY MODEL
The utility model discloses an overcome the big problem of traditional rural electric network circuit energy consumption that exists among the prior art, provide a line voltage automatic regulating ware that has the energy-conserving advantage of loss reduction now.
The utility model discloses a line voltage automatic regulator, including common coil, series coil and measuring coil, common coil on connect current transformer, the series coil on be equipped with taking a percentage of a plurality of equipartition, every take a percentage the input respectively with on-load tap-changer electric connection, measuring coil and series coil pass through the magnetic induction and be connected.
The utility model discloses based on self coupling voltage regulating transformer, the coil of this transformer divide into the triplex, and they are public coil, series coil and measuring coil respectively, and wherein, current transformer is used for gathering and the current value in the detection circuitry. The series coil is a winding with a plurality of taps, the taps are connected in series between the input and the output of the autotransformer through different contacts of the tap changer, and the series coil is a winding used for regulating output voltage; the common coil is a common winding which can generate a magnetic field for transferring energy. The measuring coil is used for providing voltage for measurement.
The utility model has the advantages of good loss reduction and energy saving effect and simple structure.
