Fig. 2 is the wiring diagram of reactive power automatic compensation control device of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail, to make those skilled in the art's referenceDescription word can be implemented according to this.
As shown in Figure 1, the invention provides a kind of reactive power automatic compensation control device, place in circuitCurrent transformer, generation current signal, this current signal transfer, to current acquisition signal, is converted into electric currentData signal, and send this signal to processor, the owe electricity of processor to received signal and settingStream blockade value compares, and undercurrent blockade value herein can be by panel design is set, withThe action effect of large this device of performance, when the current digital signal value of gained is less than set undercurrent envelopeWhen drop lock, now processor sends low capacity the control of reactive power compensating circuit working, carries out inactive power compensation,And the control of reactive power compensating circuit is in off-state; The current digital signal value obtaining when processor is greater than instituteArrange undercurrent blockade value time, processor sends control instruction, low capacity the control of reactive power compensating circuit is disconnectedOpen, the control of reactive power compensating circuit starts to carry out inactive power compensation; Like this by low capacity reactive-load compensation controlThe synergy of circuit processed and merit compensation control circuit, power ratio control factor value is more than 0.9. This deviceIn real panel show in real time power factor value, power factor value is carried out to real time record, facilitate basisActual conditions are reasonably adjusted.
By reactive power self-compensating controlling device panel, undercurrent blockade value is set, when induced-current is less thanWhen undercurrent blockade value, low capacity Reactive Power Control circuit start, adjusts available power factor value, carriesHigh power supply quality, meanwhile, the display floater in described control device shows power factor value always, doesTo the effect of monitoring in real time, this device also carries out the detection of voltage change to two other circuit, as figureSampling current on 2 and sampling voltage.
In the present invention, by increasing a low capacity Reactive Power Control circuit, guarantee when less in circuitWhen inductance current, provide higher power factor value. Meanwhile, the present invention has realized automatic switching, improvesPower supply quality, bring corresponding economic benefit to enterprise.
Although embodiment of the present invention are open as above, it is not restricted to description and enforcement sideListed utilization in formula, it can be applied to various applicable the field of the invention completely, for being familiar with abilityThe personnel in territory, can easily realize other amendment, therefore do not deviate from claim and etc. homotypeEnclose under limited universal, the present invention is also little to be limited to specific details and to illustrate here and the figure describingExample.
