Operation principle: this fling-cut switch can divide the apotype capacitance compensation switch to use as three-phase, a phase that on the copper first brace 2-7 of each silicon controlled module 2, connects three-phase alternating-current supply during use, make the copper second brace 2-8 and be accordingly on the corresponding contact of capacitor group that star meets (Y), on the power supply input wires piece 3-3 of DC power supply access continuous-current plant 3 that again will be external.After the energized, the output of continuous-current plant 3 is transported to 12V or 5V power supply (present embodiment adopts the 12V power supply) on the first external link s1 and the second external link s2 of control circuit 2-11 of each silicon controlled module 2 by 3 groups 6 DC power supply output lead 3-4, direct current is behind the positive pole of continuous-current plant 3, successively by indicator light HL, 1 pin of the second photoelectrical coupler U2 and 3 pin, diode D1,1 pin of the first photoelectrical coupler U1 and 3 pin, get back to the negative pole of continuous-current plant 3 after the resistance R 4, when direct current during through 1 pin of 1 pin of the second photoelectrical coupler U2 and 3 pin and the first photoelectrical coupler U1 and 3 pin, lumination of light emitting diode in the corresponding photoelectrical coupler, thereby make the light-receiving device of this photoelectrical coupler be switched on, and make the state that is in conducting between 2 pins of output of each photoelectrical coupler.
When being in the state of conducting between 2 pins of the output of 2 photoelectrical couplers, the copper first brace 2-7 for some silicon controlled modules 2, the voltage of certain alternating current A that is imported in a flash on the occasion of the time, should after the diode D3 step-down of electric current elder generation by the second current-limiting circuit 2-11-2 of control circuit 2-11 of voltage, transport to the control utmost point of second largest power scr VT2 and 6 pin of the second photoelectrical coupler U2; Because the described function of current on the occasion of voltage has had a pressure drop at the voltage of the control utmost point of second largest power scr VT2 with the voltage that acts on the negative electrode of second largest power scr VT2, so second largest power scr VT2 continues the state of remain off; Transport to the second photoelectrical coupler U2 6 pin on the occasion of the electric current of voltage successively through the second photoelectrical coupler U2, resistance R 1 back 6 pin by the first photoelectrical coupler U1 flow into the first photoelectrical coupler U1 and flow out the first photoelectrical coupler U1 by 4 pin of the first photoelectrical coupler U1 again, the electric current on the occasion of voltage that flows out the first photoelectrical coupler U1 is divided into 2 the tunnel, one the tunnel transports to the control utmost point of first power scr VT1, transport to the negative pole of first power scr VT1 after resistance R 2 step-downs of another road through the first current-limiting circuit 2-11-1 of control circuit 2-11, because the described function of current on the occasion of voltage is higher than voltage on the negative pole that acts on first power scr VT1 at the voltage of the control utmost point of first power scr VT1, and make first power scr VT1 conducting, thereby being in after the alternating current A of voltage flows through the copper first brace 2-7 of copper first brace 2-7 place input, anode by first power scr VT1 flows into first power scr VT1, negative electrode by first power scr VT1 flows out again, flow through successively again behind the first bridge joint copper coin 2-6-1 and the copper second brace 2-8 and flow out this fling-cut switch, realized that silicon controlled module 2 is in the conducting on the occasion of voltage time of the alternating current of input.
The copper first brace 2-7 for above-mentioned silicon controlled module 2, when the alternating current A that is imported by on the occasion of voltage vanishing voltage the time, second largest power scr VT2 continues the state of remain off, and first power scr VT1 is then become by state by conducting state.Immediately, the alternating current A that is imported is then become the electric current of negative voltage by no-voltage, at this moment, the electric current of this negative value voltage elder generation transports to the control utmost point of second largest power scr VT2 and 6 pin of the second photoelectrical coupler U2 after being boosted by the resistance R 3 of the second current-limiting circuit 2-11-2 of control circuit 2-11; Because the function of current of described negative value voltage has had one to boost at the voltage of the control utmost point of second largest power scr VT2 with the voltage that acts on the negative electrode of second largest power scr VT2, and make second largest power scr VT2 conducting, thereby after the alternating current A that is in negative value voltage of copper first brace 2-7 place input flows through the copper first brace 2-7 and the second bridge joint copper coin 2-6-2 successively, negative electrode by second largest power scr VT2 flows into second largest power scr VT2, anode by second largest power scr VT2 flows out again, flow through again behind the copper second brace 2-8 and flow out this fling-cut switch, realized the conducting of silicon controlled module 2 when the alternating current of input is negative value voltage.The electric current of the negative value voltage of above-mentioned 6 pin of transporting to the second photoelectrical coupler U2 is successively through the second photoelectrical coupler U2, resistance R 1 back 6 pin by the first photoelectrical coupler U1 flow into the first photoelectrical coupler U1 and flow out the first photoelectrical coupler U1 by 4 pin of the first photoelectrical coupler U1 again, the electric current that flows out the negative value voltage of the first photoelectrical coupler U1 is divided into 2 the tunnel, one the tunnel transports to the control utmost point of first power scr VT1, after boosting, the diode D2 of the first current-limiting circuit 2-11-1 of another road process control circuit 2-11 transports to the negative pole of first power scr VT1, because the function of current of described negative value voltage is higher than the voltage that the control that acts on first power scr VT1 is extremely gone up at the voltage of the negative pole of first power scr VT1, and make that first power scr VT1 can not conducting, still be in by state, thereby the alternating current A that is in negative value voltage of input can not pass through first power scr VT1, can only flow through from above-mentioned second largest power scr VT2.
