Brief description
Fig. 1 is the circuit structure diagram of the present invention.
Specific embodiment
With reference to the accompanying drawings and examples invention is described in detail.
As shown in figure 1, dry type wide scope manostat proposed by the present invention, including transmission line of electricity and central processing unit.
Live wire one end of transmission line of electricity is input voltage L1, and the other end is output voltage L2, and transmission line of electricity is installed successively
There is the first chopper HK1, main transformator TB1, secondary transformer TB2, the first A.C. contactor KM1, output current table and defeated
Go out voltmeter, be provided with the 3rd chopper HK3 between main transformator TB1 and secondary transformer TB2, output voltage meter is used for detecting
Voltage between output voltage meter, and the measurement circuit of voltmeter is provided with the second A.C. contactor KM2, central processing unit controls
It is connected to the first chopper, the first A.C. contactor, the 3rd chopper and the second A.C. contactor.Central processing unit is connected to
The two ends of two A.C. contactor KM2.Central processing unit adopts KWGD intelligent controller（In dashed rectangle in figure one）
Second chopper HK2 is additionally provided with transmission line of electricity, this second chopper two ends connects city's electric power system and output electricity respectively
Flow table, the second chopper controls connection by described central processing unit.Central processing unit adopts single-chip computer control system.Secondary transformation
Device is using the single-circuit transformer with the multigroup voltage of six taps.
During normal work, input voltage L1 samples voltage signal through electricity on chopper HK1 combined floodgate, output sampling transformator
Become digital signal through A/D conversion after delivering to panel rectifying and wave-filtering and deliver to central processor CPU and be analyzed comparing and send finger
Make control relay switching single-circuit transformer（Secondary change）Tap voltage makes main transformer primary obtain relevant voltage and make use of transformator sense
Voltage superposition principle is answered so that the voltage of main transformer secondary L2 is changed with main transformer primary voltage and change, so that output voltage is steady all the time
It is scheduled in range of set value；The time delay in the range of setting voltage of voltage regulation of cpu monitor output voltage sends signal for 5 seconds and controls exchange to connect
The stable voltage of tentaculum KM1 adhesive output；When output voltage because other reasons and fault make voltage exceed setting protection magnitude of voltage
