Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
As shown in Figure 1, the utility model is to implement like this:
In the drawings, the benchmark input end 28 of numerical control voltage-stabilizing system delivered to voltage reference by digital to analog converter DAC by microprocessor 11 in the node control system 10, microprocessor 11 is connected in series with LCD display 12 and keyboard 13, operates by LCD display 12 video datas with by 13 pairs of electricity-saving control systems 10 of keyboard.Microprocessor 11 also is connected to PC or GSM/GPRS module 161 etc. by the RS232/RS485 serial ports in addition.Wherein the numerical control voltage-stabilizing system is a three-phase numerical control voltage-stabilizing system; A phase numerical control voltage-stabilizing system 21 in the drawings is made of compensator transformer 24, many tap transformers 25, solid-state switch array 26, MCU, mistake/under-voltage protecting circuit 27, analog to digital converter ADC and AC/DC converter etc.; wherein MCU and mistake/under-voltage protecting circuit 27 are electrically connected; gather current voltage and current value by the sample circuit that AC/DC converter, ADC converter are formed, and then with data be sent to MCU again after voltage reference is compared and calculate.
Shown in figure, starting-up signal 16, by-passing signal 17 and fault-signal 18 all close through the photoelectricity corner and are input to microprocessor 11 after device 15 photoelectricity are isolated, and microprocessor 11 is handled (comprise deliver to that LCD shows and as the judgement symbol of next step action of electricity-saving appliance) to these signals.Microprocessor 11 can be connected with PC by RS232/RS485 serial ports or GSM/GPRS module.Microprocessor 11 also can close by the photoelectricity corner and output a control signal to long-range bypass control loop 171 after device 15 photoelectricity are isolated or remote on-off control loop 181 carries out Long-distance Control.A phase numerical control voltage-stabilizing system output 211, the output 221 of B phase numerical control voltage-stabilizing system and the C digital processes formed via voltage transformer (VT) 14, AC/DC converter and ADC converter of numerical control voltage-stabilizing system output 231 mutually are distributed to microprocessor 11.
Principle of work of the present utility model is: the microprocessor 11 in the electricity-saving control system 10 (is the speed of slope lifting according to the slope that the user sets, unit is S/DAC, its implication is needed second number of the least significant bit (LSB) of the every rising or the magnitude of voltage that descends), by the DAC digital to analog converter, progressively increase or reduce voltage reference in the numerical control voltage-stabilizing system, and the numerical control voltage-stabilizing system is adjusted voltage according to this voltage reference that constantly changes, when output voltage values reaches target voltage values, microprocessor just stops voltage reference and changes, and numerical control this moment voltage-stabilizing system just is stabilized in magnitude of voltage the target voltage values place.So voltage can not rise sharply or be plummeted to target voltage values, but progressively change to target voltage, prolong the serviceable life of various kinds of equipment by the slope of the slope of setting.
