Description

Technical Field

[0001] The invention relates to the technical field of circuit breakers, and in particular to an intelligent test device for an anti-tripping circuit of a circuit breaker. Background Art

[0002] Circuit breaker is a switch device that can connect and disconnect circuits under normal circumstances, and quickly cut off fault current when a fault occurs, to protect the safe and stable operation of power equipment and systems. It is usually composed of contact system, arc extinguishing system, operating mechanism, release and other parts. The contact system is responsible for the connection and disconnection of the circuit; the arc extinguishing system quickly extinguishes the arc when disconnecting the circuit to prevent the arc from damaging the equipment; the operating mechanism is used to control the opening and closing action of the circuit breaker; the release triggers the circuit breaker to trip when the fault current reaches a certain value.

[0003] However, when closing the circuit manually or automatically, if the operating control switch is not reset or the control switch contacts or the automatic device contacts are stuck, a dangerous situation will occur. At this time, the protection action causes the circuit breaker to trip, but since the above problem has not been solved, the closing signal may be triggered again, causing the circuit breaker to "trip-close" multiple times, the so-called jump. This jump fault is very dangerous to the circuit breaker itself, because the frequent opening and closing actions will cause huge impact and wear on the mechanical mechanism of the circuit breaker, which is easy to cause damage to the mechanism. As time goes by and the number of jumps increases, this damage may continue to accumulate, and in severe cases it may even cause the circuit breaker to explode, causing the accident to further expand and posing a serious threat to the safe operation of the power system. Summary of the invention

[0004] The present invention provides an intelligent test device for circuit breaker anti-tripping circuit, which can test the functional integrity of anti-tripping circuits in different forms. When abnormal conditions occur during manual or automatic closing, it can effectively prevent abnormal phenomena from occurring in the circuit breaker, ensuring that the circuit breaker can operate safely and stably.
