Beschreibung
Zusammenfassung:	The utility model provides a circuit breaker control loop and a circuit breaker anti-tripping module, and belongs to the technical field of high-voltage electrical appliances. The circuit breaker anti-tripping module comprises a current type relay and two voltage type relays; a coil of the current type relay is connected in series with a first normally-closed contact of the first voltage type relay and then is connected in series with a closing loop of the circuit breaker; a branch formed by a coil of the current type relay, a first normally-closed contact of the first voltage type relay, a circuit breaker contact and a closing coil serves as a first branch; a normally open contact of the current type relay is connected in series with a coil of the second voltage type relay and then is connected in parallel with the first branch; a normally open contact of the second voltage type relay is connected in parallel with a normally open contact of the current type relay; a normally-closed contact of the current typ
