When closing the working voltage of power capacitor unit outside the system voltage threshold interval, then cut-out is passed under the central processing unit
Information to Intelligent projection switch power capacitor unit Intelligent projection switch.Such as：System voltage threshold interval is system volume
Constant voltage ± 15% is regarded as under-voltage if less than -15%；If high pressure+15% regards as overvoltage.Therefore, of the invention
It transfinites protection with overvoltage, under-voltage protection and harmonic voltage/electric current, when Intelligent projection switch power capacitor comes into operation,
When Intelligent projection switch power capacitor overcompensation or very few compensation, the radio communication type Intelligent Reactive Compensating Controller
It will be controlled.
When the current information of Intelligent projection switch power capacitor unit is less than the load low current threshold value, then in described
Central processor no longer passes down the switching control information.It is small ought to detect that the actual current in load system is less than the load
When current threshold, such as national standard limit is 150mA, may be configured as 50mA in the present invention, is higher than 3 times of national standard, is protected into low current
Shield stage, controller will be defaulted as detection inaccuracy, and at this moment load system is also not need reactive-load compensation, in order to avoid going out
Now control malfunction, controller just no longer sends out input and instructs, still, if there is the capacitor branches in operation at this time, it will
Automatic sequence exits.It may also be said that when in electricity system without load or relatively light load, controller is idle.Therefore,
The present invention has low current blocking function.
After the Intelligent projection switch power capacitor unit of cut-out waits for the delay threshold, under the central processing unit
Input information is passed to the Intelligent projection switch of Intelligent projection switch power capacitor unit, controls the Intelligent projection switch electric power
Capacitor unit puts into three phase network again.Therefore, input makes again immediately after the present invention can effectively avoid capacitor from cutting off
Influence of the residual voltage of used time to electrical equipment.
The central processing unit read and record automatically each Intelligent projection switch power capacitor unit operating time,
History working condition, when the operating time of Intelligent projection switch power capacitor unit is more than the operating time threshold value, then institute
It states central processing unit and passes cut-out information down to the Intelligent projection switch of Intelligent projection switch power capacitor unit, the centre
The history working condition that device refers to each Intelligent projection switch power capacitor unit is managed, lower biography input information is identical to another
The Intelligent projection switch power capacitor unit of capacity.There is the service life of the total switching frequency of regulation capacitor in national standard, and common
Controller exists preferentially allows former group capacitors to be devoted oneself to work repeatedly every time, and remaining capacitor group is always at not later
The problem of putting into or being rarely employed.The purpose that the operating time threshold value is arranged is when group capacitor work to certain time length
When, force disconnect simultaneously controls another group capacitor and comes into operation, therefore, the present invention can ensure every capacitor in turn, it is balanced
Work extends the longest service life of compensation equipment.
When the power factor of Intelligent projection switch power capacitor unit is less than the power factor threshold, then in described
Central processor passes down cut-out information to the Intelligent projection switch of Intelligent projection switch power capacitor unit.Be arranged the power because
Number threshold value is relatively low because of load system average power factor, it is meant that this compensation device of capacitor unit, which does not play, answers
There is (such as capacitor damage, cisco unity malfunction), power factor (PF) is relatively low to make three phase network electric energy loss increase, and give
Country and enterprise cause prodigious waste.
