Description
Technical field
The utility model belongs to commutation control technology field, and in particular to a kind of intelligent three-phase adjuster.
Background technology
Currently, in state's grid company low-voltage network system, there is a large amount of single-phase, asymmetric, non-linear, impacts
Property load.Three-phase load system changes at random, these loads can make distribution system generate three-phase imbalance, and three-phase load is not
Balance can lead to the imbalance of power supply system three-phase voltage, electric current, cause electrical network negative phase-sequence voltage and negative-sequence current, influence matter of powering
Amount, and then increase line loss, reduce power supply reliability.
Invention content
The purpose of this utility model is that it is a kind of simple in structure for problems of the prior art offer, it is easy to operate
Intelligent three-phase adjuster.
The technical solution of the utility model is：
A kind of intelligent three-phase adjuster, including change controller, if the change controller is wirelessly connected by GPRS
Dry phase-change switch, each phase-change switch are connected on the three-phase circuit of user.
Specifically, the change controller includes dsp controller, silicon-controlled and relay, it is described silicon-controlled and after
Electric appliance is connected in parallel.
Specifically, the phase-change switch include it is several by two-phase thyristor and contactor be connected in parallel the unit formed and
Trigger board.
The utility model has the beneficial effects that：The change controller of the utility model will be silicon-controlled in parallel with relay, adopts
It is controlled with DSP, (is i.e. put into when voltage zero-cross, when current over-zero by the silicon-controlled operating passing zero that undertakes in the moment for putting into and cutting off
Excision), to which guard relay connects operation.Due to silicon control zero-cross switching, has the characteristics that no-flashy-flow, and turn-on time pole
It is short, it will not cause to generate heat, magnetic latching relay is in actuation and disconnection moment does not all shove and spark is to power grid without impact
Ideal three-phase imbalance administers switch.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of phase change switch.
1 change controller, 2 phase-change switches, 3 bidirectional thyristors, 4 contactors, 5 trigger boards.
Specific implementation mode
It is a kind of structural schematic diagram of intelligent three-phase adjuster, including change controller 1, the commutation as shown in Figure 1
Controller 1 is wirelessly connected several phase-change switches 2 by GPRS, and each phase-change switch 2 is connected on the three-phase circuit of user.It is described
Change controller 1 include dsp controller, silicon-controlled and relay, the silicon-controlled and relay is connected in parallel.Described
Phase-change switch 2 is connected in parallel the unit formed and trigger board 5 including several by two-phase thyristor 3 and contactor 4, as shown in Figure 2.
Change controller 1 provided by the utility model is according to each mutually electricity of 2 size of current smart allocation of each group phase-change switch
Stream, it is ensured that three-phrase burden balance.Phase-change switch 2 using 3 parallel contactor 4 of two-phase thyristor structure, commutation process do not have a power failure,
It is fast without impact, switch speed, by GPRS wireless telecommunications between phase-change switch 2 and change controller 1, it is easy to extend non-maintaining.
Change controller 1 provided by the utility model is the control terminal of whole device, and per covering device, only there are one change
Phase control device 1.Change controller 1 is responsible for the various status informations and data of acquisition whole device, is sent out respectively by logical operation
The manipulation of whole device is completed in kind instruction, it detects voltage signal with network bus；Receive the load current that phase-change switch 2 uploads
Data, the computational load degree of balance and distribution situation send out commutation order by analyzing to calculate to each phase-change switch 2；Reception is changed
Then the operating status and fault message that mutually switch 2 uploads make corresponding control operation.
Phase-change switch 2 is the branch and executing agency of intelligent three-phase adjuster described in the utility model, according to distribution transforming
Capacity and the distribution situation difference of load can flexibly select the capacity and quantity of phase-change switch 2.It is responsible for acquiring load current number
According to being uploaded to change controller 1 by GPRS wireless telecommunications together with the status information of itself and receive changing for change controller 1
Phase command carries out commutation operation；The error protection order for receiving change controller 1 is operated accordingly；Show the operation of itself
Status information.
Often covering intelligent three-phase adjuster device provided by the utility model, only there are one change controllers 1, but commutation is opened
The quantity for closing 2 is indefinite, according to the difference of field application situation, is equipped with phase-change switch 2 in varying numbers.Phase-change switch 2 with
Realize that information exchange, such field application are flexible for installation between change controller 1 by way of GPRS wireless telecommunications.Because adopting
GPRS communication modes, can be periodically to control terminal (such as mobile phone) distributing device operation information of user per covering device.
Finally it should be noted that:Above example is only to illustrate the technical solution of the utility model rather than limits it
System；Although the utility model is described in detail with reference to preferred embodiment, those of ordinary skill in the art should
Understand：It can still modify to specific embodiment of the present utility model or some technical characteristics are equally replaced
It changes；Without departing from the spirit of technical solutions of the utility model, should all cover in the claimed technical solution of the utility model
In range.
