Referring to fig. 1, a breaker device of intelligence combined floodgate, includes the circuit breaker body (not drawn), the circuit breaker body is equipped with live wire interface 101, zero line interface 102, controlling means 106, charges energy storage unit 105, charging circuit and current transformer 104, be connected with between live wire interface 101 and the zero line interface 102 and get electric branch 103, current transformer 104 sets up on getting electric branch 103, charging circuit includes: the charging circuit comprises a first resistor R1, a second resistor R2, a third resistor R3, a zener diode D1 and a photoelectric coupler U1, wherein a collector and an emitter of the photoelectric coupler U1 are connected in series to the power-taking branch 103, the first resistor R1 is connected in series to the power-taking branch 103, the upper end of the second resistor R2, the anode of the charging energy storage unit 105 and the anode of a power supply end of the control device 106 are respectively connected with the anode output end of the current transformer 104, the lower end of the second resistor R2 is respectively connected with the anode of the photoelectric coupler U1, the upper end of the third resistor R3 and the cathode of the zener diode D1, and the lower end of the third resistor R3, the anode of the zener diode D1, the cathode of the charging energy storage unit 105 and the cathode power supply end of the control device 106 are respectively connected with the cathode output end of the current transformer 104.
The charging energy storage unit 105 may store electrical energy, and the charging energy storage unit 105 supplies power to the control device 106. When the charge of the charge energy storage unit 105 is normal, the voltage across the charge energy storage unit 105 remains unchanged, and at this time, the reverse direction of the zener diode D1 is broken down, and the current flows from the positive electrode of the charge energy storage unit 105, and returns to the negative electrode of the charge energy storage unit 105 through the second resistor R2 and the zener diode D1.

The collecting electrode and the emitting electrode of the photoelectric coupler U1 are conducted, so that the electricity taking branch circuit 103 has current to pass through, the current transformer 104 outputs current, the current charges the charging energy storage unit 105, the voltage at two ends of the charging energy storage unit 105 is increased, when the voltage is increased to a certain degree, the voltage at two ends of the third resistor R3 is increased, the voltage stabilizing diode D1 is broken down, at the moment, the collecting electrode and the emitting electrode of the photoelectric coupler U1 are cut off, and the electricity taking branch circuit 103 is not electrified. By repeating the above steps, the charging energy storage unit 105 can maintain a certain amount of electricity, and the control module can maintain working.
The utility model discloses a setting is got electric branch 103 to utilize charging circuit to maintain the electric quantity for charging energy storage unit 105, make control module maintenance work then, solved the easy problem of lacking of electricity of control module.
