基于录波数据的配电网断路器状态监测的研究

Research on Status Monitoring of Distribution Network Circuit Breakers Based on Recorded Data

为进一步增强断路器状态监测的实践应用效果,本文结合配电自动化终端具备的操作录波功能,采用故障录波装置记录断路器在分/合闸过程中的电气量数据,近似测算分/合闸的时间,以标识断路器的运行状态,实现对断路器分/合闸状态的有效判断。基于录波数据的断路器状态监测方法采用电流互感器感知断路器状态,仅需在配电自动化系统中通过完成终端软件的设置实现,无需其他硬件投入,在满足配网设备状态监测可靠性要求的同时,兼具技术可行性与经济性。

To further enhance the practical application effect of circuit breaker status monitoring,this paper combines the operation recording function of the distribution automation terminal and uses a fault recording device to record the electrical data of the circuit breaker during the opening/closing process,approximately calculating the opening/closing time,in order to identify the operating status of the circuit breaker and achieve effective judgment of the opening/closing status of the circuit breaker.The circuit breaker status monitoring method based on recorded data uses current transformers to sense the circuit breaker status.It only needs to be achieved through the completion of terminal software settings in the distribution automation system,without the need for other hardware investment.While meeting the reliability requirements of distribution network equipment status monitoring,it also has technical feasibility and economic efficiency.
