Accompanying drawing explanation
Fig. 1 is the circuit block diagram of power back-off Distribution Network Equipment；
Fig. 2 is the schematic diagram of ghyristor circuit.
Detailed description of the invention
As shown in Figure 1, 2, a kind of power back-off Distribution Network Equipment, including: current analog signal group, voltage analog signal
Group, processor, ghyristor circuit, pulsed triggering circuit, current analog signal group, the outfan of voltage analog signal group and process
Device is connected, and described processor is connected with ghyristor circuit by pulsed triggering circuit, the input of described processor and keyboard
Being connected, the video output terminals of described processor is connected with display screen；Described ghyristor circuit is by three groups of controllable silicons T1, T2, T3
Connect three connection end points of electric capacity C1, C2, C3 respectively with ring and be connected composition, and each controllable silicon T1, T2, T3 respectively with diode
D1, D2, D3 are connected in parallel, and its controllable silicon polarity is connected for complementation with diode polarity.
The using method of a kind of power back-off Distribution Network Equipment, the current transformer group of employing, it is mutual that setting makes often to organize electric current
The electric current of sensor output is 10:1, and specified input current is 10mA, specified is output as 1mA；By voltage transformer circuit and
Current transformer, by the three-phase A of sampling, each phase voltage of B, C, each line current are converted into the ac voltage signal of-5V+5V
Sending into A/D change-over circuit and carry out exchange conversion, no matter nominal input voltage has much voltage transformer, adjusts and makes input current
Value be 2mA, then another side also can sense output one identical electric current 2mA, send into A/D change-over circuit carry out exchange become
Change；Treated device Industrial PC process, then by pulsed triggering circuit send to ghyristor circuit three groups of controllable silicon T1,
T2, T3 conduction amount, the ring that regulation connects connects electric capacity C1, C2, C3 combined value and Distribution Network Equipment is carried out power back-off；And in display
Screen display illustrates data.
