Monitoring system of tripping pulse of breaker

Abstract

The invention discloses a monitoring system of a tripping pulse of a breaker. The system comprises a tripping pulse monitor and a tripping signal reader. The tripping signal reader reads monitored tripping generation time and a monitored tripping pulse width from the tripping pulse monitor as well as converts the read tripping generation time and the read tripping pulse width into GPS time service time to carry out displaying; in order to solve a breaker's non-fault trip accident without a protection action signal, it can be rapidly discriminated that whether the breaker's tripping action is caused by a secondary circuit fault or by itself reason, so that a tripping reason can be determined; and thus, a corresponded measure is taken to enable the breaker to work normally again. The monitoring system has characteristics of small and exquisite appearance, low power dissipation, and maintenance-free property; besides, the monitoring system can be installed without need of power failure; and monitoring points can be arranged reasonably and a fault searching range can be rapidly and effectively reduced. Moreover, the tripping signal reader is utilized to read data related to tripping from the tripping pulse monitor in a wireless communication mode to conveniently carry out an analysis and comparison, so that the fault can be eliminated rapidly and safe operation of the system can be guaranteed.

Description

Technical field [0001] The present invention involves a tracting pulse signal monitoring system. Background technique [0002] The high -voltage circuit breaker in the power system occurs when the high -voltage circuit breaker jumps, which brings certain harm to the safe and stable operation of the system.Generally, there are two reasons for the sneaky -jump circuit breaker. First, the cardiac failure caused by the mechanical failure of the circuit breaker mechanism, and the second is the trip of the secondary circuit failure.Because the electrical circuits that may cause the trail to disconnect do not have a corresponding checkpoint monitoring equipment with a record function, it often makes the circuit breaker unreliable after the sneaky -jump of the circuit breaker is a sneak jump caused by the institution, or the secret caused by the second loop failure.Jump, timely and labor -intensive regions to identify the reasons for stealing jumps to eliminate low failure efficiency. I...

Problems solved by technology

Since there is no corresponding trip pulse monitoring device with recording function for each electrical circuit that may cause the circuit breaker to trip, it is often impossible to reliably distinguish whether the sneak trip is caused by the mechanism or the secondary circuit fault after the circuit breaker trips. Jumping, it is time-consuming and laborious to identify the reasons for stealing jumps, and the efficiency of troubleshooting is low
