Compensating electric capacity is loaded by the access of high-power contactless switch, fuse and vacuum circuit breaker between triple line, signal acquisition list
Member collection three-phase voltage and current signal access controller, the controller control output par, c pass through high power contactless respectively
The input of switch control capacitive coupling and point benefit electric capacity.
Described three-phrase burden balance reactive power compensator, controller includes central processing unit, data storage, communication unit
Member and human-computer interaction interface, signal gathering unit output three-phase voltage and current signal connection central processing unit, the data
Memory, communication unit and human-computer interaction interface and central processing unit are interconnected, described in control output par, c controlled connection
Central processing unit.
Described three-phrase burden balance reactive power compensator, including some groups of single-phase compensation capacitors and some alternate group of benefits
Capacitor is repaid, every group of compensation capacitor is respectively connected to three by high-power contactless switch, fuse and vacuum circuit breaker parallel connection
Phase line, is then accessed between triple line and zero line or between triple line, the controlled companies of fling-cut switch QP by fling-cut switch QP
It is connected to controller.
The beneficial effects of the utility model：
1st, the utility model three-phrase burden balance reactive power compensator, by signal acquisition, data storage, switch, capacitor
Deng composition, by traditional common benefit, point mend or altogether mend+point mend capacitor compensation mode, be improved to it is alternate compensation+single-phase point benefit
Capacitor compensation mode.Constitute new Reactive Compensation Mode.While reactive-load compensation is carried out, there are cause transformer three
Phase load has obtained balance adjustment, effective for industrial and civilian occasion.
2nd, the utility model three-phrase burden balance reactive power compensator, using microprocessor as core, collection in real time, dynamic point
The parameters of power network are analysed, by capacitive coupling, while carrying out reactive-load compensation to related two-phase, also between the two-phase
Active power is balanced, and point benefit electric capacity further improves power factor as the supplement of capacitive coupling device.The utility model knot

Embodiment
Below by embodiment, the technical solution of the utility model is described in further detail.
Embodiment 1, the program is with two groups of single-phase compensating electric capacities, exemplified by three groups of alternate compensating electric capacities.
Referring to Fig. 1, Fig. 2, three-phrase burden balance reactive power compensator of the present utility model, including controller, fling-cut switch,
Compensation capacitor, the compensation capacitor is included using point benefit electric capacity of star-like connected mode and using triangle connected mode
Alternate compensating electric capacity, described point mend electric capacity pass through high-power contactless switch, fuse and vacuum circuit breaker access load three
Between phase line, the alternate compensating electric capacity passes through high-power contactless switch, fuse and vacuum circuit breaker access load three-phase
Between line, signal gathering unit collection three-phase voltage and current signal access controller, the controller control output par, c point
The input of capacitive coupling and point benefit electric capacity is not controlled by high-power contactless switch.
Fling-cut switch QP controls the access threephase load of whole three-phrase burden balance reactive power compensator, vacuum circuit breaker
QF1-QF6 controls point access for mending electric capacity and alternate compensating electric capacity respectively, and controller passes through according to the load actual conditions of detection
Whether is the conducting of control section control high-power contactless switch, and the access of electric capacity and/or alternate compensating electric capacity is mended in control point, real
Reactive-load compensation now is carried out to power network, regulation can be balanced to three-phase load again.
