Abstract
Disclosed in the utility model is an anti-tripping loop of a high-voltage circuit breaker. Therefore, a problem that the anti-tripping relay maintains the motion state without return after circuit breaker closing because of over low return voltage of the anti-tripping relay with the anti-tripping loop of the existing high-voltage circuit breaker and thus superposition or continuous closing can not be realized and no universality is realized can be solved. The anti-tripping loop comprises a circuit breaker operation box tripping position monitoring loop, a circuit breaker remote control closing loop, and a circuit breaker closing control loop; and a tripping position monitoring relay in the circuit breaker operation box tripping position monitoring loop is connected in series to a circuit breaker normally-closed auxiliary contact. When the circuit breaker remote control closing loop make motion, the circuit breaker normally-closed auxiliary contact changes the position; the voltage of the anti-tripping relay is reduced to be below the return voltage and then automatic return is realized; and re-motion of the closing control loop can be realized to realize next-time closing. The anti-tripping loop has the simple structure and stable functions; and universality of the operation box tripping position relay of the high-voltage circuit breaker can be improved.
