断路器运行在线自动监测

Automated Monitoring for Circuit Breaker on Line

断路器在电力系统中非常重要,用它来切换其他设备在工作与停止两种状态。断路器的可靠运行对重新配置电力系统的能力至关重要,并且可靠性可以通过定期检查和维护来保证。现在可以采用一种自动断路器监测系统来监测断路器的控制电路。系统包括一套新的断路器监测数据采集智能电子设备,它位于断路器上,用于获得关于实时运行的详细信息。本文也论证了系统范围的数据分析的应用,它使得追踪断路器的开关序列成为可能,同时也给出了关于断路器开关序列的性能和最终结果的结论。

Circuit breakers （CBs） are very important elements in the power system. They are used to switch other equipment in and out of service. Reliable operation of circuit breakers is critical to the ability to reconfigure a power system and can be assured by regular inspection and maintenance. An automated circuit breaker monitoring system is proposed to monitor circuit breaker＇s control circuit. The system consists of a new CB monitoring data acquisition IED that is located at circuit breaker and captures detailed information about its operation in real-time, An application of system wide data analysis is demonstrated. It makes possible to track the circuit breaker switching sequences and make conclusions about their performance and final outcome.
