Abstract
The invention relates to a driving energy storage detection circuit of a breaker. The driving energy storage detection circuit comprises an energy storage capacitor, two resistors, a diode and an optical coupler, wherein a first resistor and a second resistor are connected with each other in series, and then are connected in parallel with the energy storage capacitor; a contact of the first resistor and the second resistor are connected with the cathode of the diode, and the anode of the diode is connected with the anode of a luminous tube in the optical coupler; the cathode of the luminous tube in the optical coupler is connected with the cathode of the energy storage capacitor; and the emitting electrode of a photosensitive tube in the optical coupler is grounded, and the collector electrode of the photosensitive tube in the optical coupler is connected with a central controller in the breaker when the circuit is put in to use. When the circuit is put into use, when the voltage value of the energy storage capacitor reaches to a fixed value, a signal is sent to the central controller, and the central controller executes protection motion on the basis of the signal, therefore, the reliability of tripping control is guaranteed.
