| titleOfInvention | Overcurrent sectional type voltage protector protection circuit for vacuum circuit breaker |
| abstract | The invention discloses an overcurrent sectional type voltage protector protection circuit for a vacuum circuit breaker, and belongs to the technical field of electric appliance protection. The system comprises a first leakage branch circuit, a third leakage branch circuit, a second leakage branch circuit and a leakage standby circuit, wherein the first leakage branch circuit, the second leakage branch circuit and the third leakage branch circuit are connected in parallel at the output end of a power supply main circuit; the second current monitoring comparator and the nonlinear resistor are respectively arranged at the current input end and the output end of the first leakage branch circuit; the leakage standby circuit is connected with the first leakage branch in parallel, and two ends of the leakage standby circuit are respectively and electrically connected with the power supply main circuit and the grounding circuit; a first current monitoring comparator is arranged on the power supply main circuit; and a starting circuit is arranged between the third leg of the first current monitoring comparator and the grounding circuit. The invention protects each other through the discharge gap and the nonlinear resistor, and is provided with the standby circuit to dump the clockwise current generated by the instantaneous overload voltage, thereby protecting the circuit and the electric appliance. |
