The electric equipments such as lampblack absorber, computer, micro-wave oven, electromagnetic oven, electricity-saving lamp, these single-phase equipment electric power factors are relatively low, make
With a large amount of reactive powers of middle consumption, cause low-voltage network electric energy loss to increase, voltage reduction, influence power distribution network it is safe and reliable and
Economical operation.At present, power factor often is improved from the mode that reactive-load compensation capacitor is accessed in distribution transformer low-pressure side, dropped
Low electric energy loss.This compensation way, because single-phase electric devices install scattered, and actual operating mode constantly changes, and leads
Cause there are a large amount of reactive currents in low-voltage distribution system, it is impossible to effectively reduce electric energy loss.Particularly when power load distance set
Middle compensation device farther out when, reactive loss on the line also increases therewith, not only consume preciousness electric energy, and cause supply
Electric line, equipment produce heat, make equipment premature aging, and serious is likely to result in switchgear house to the circuit of the transmission line of equipment
Pressure drop increases, and equipment is chronically at under-voltage running status, and then may influence electrical equipment service life, thus drawback compared with
It is many.
The content of the invention
The purpose of this utility model is to provide a kind of single-phase load reactive automatic compensation device special, to overcome prior art
Existing above-mentioned drawback.
A kind of single-phase load reactive automatic compensation device special of the utility model, it includes voltage transformer, Current Mutual Inductance

Power load live wire is connected, and lower end is connected with star-connection capacitor bank；The lower end of the star-connection capacitor bank passes through even
Wiring is connected with single-phase power load zero line.
The single-phase combination switch has three, a phase of every connection star-connection capacitor bank；The star-connection
Capacitor bank is by the capacitor bank of three different capabilities into its condenser capacity ratio is 1:2:4, three combination switches can be passed through
Switching be combined into 1,2,3,4,5,6,7 seven kind of different compensation capacity.
The controller, according to voltage transformer summation current transformer measured value under different operating conditions, calculates single-phase negative
The power factor and no-power vacancy of lotus, according to no-power vacancy, the single-phase electricity container of selection input suitable capacity, with to greatest extent
Reduce electric energy loss.
The utility model has compared with prior art：
1st, by the three-phase compensation capacitor of existing star-connection, by changing its connected mode with combination switch, as
Three single-phase electricity containers are used, and effectively reduce making and the packaging cost of single-phase electricity container.
2nd, it is easily installed near single-phase power load, idle flowing is reduced to greatest extent, reduces electric energy loss.
3rd, device volume of the present utility model is small, safe and reliable, and is easily installed and safeguards.
