【摘要】：为了监测断路器操作回路中跳/合闸回路、压板和保护出口接点的状态,并对其薄弱环节故障进行预警以避免断路器误动或拒动,设计了断路器操作回路的智能化监测系统。该系统改进了现有跳/合闸回路,并给出了系统中元件的选型与参数整定依据,能够实现跳/合闸回路的全工况监视和保护。为了实时监测断路器操作回路压板和保护出口接点的状态,实现压板误操作和保护出口接点故障报警,该系统采取了配合使用电感式接近开关和霍尔电压传感器的方法,并给出了传感器的具体安装位置。该系统采用单片机处理并上传传感器采集的现场信息,利用LabVIEW编写后台软件界面,能够实现实时状态显示、人机交互、历史数据存储和故障报警等功能。
[Abstract]:In order to monitor the status of the tripping/ closing circuit, the pressure plate and the protection outlet contact in the operation circuit of the circuit breaker, the fault of the weak link of the circuit breaker is prewarning to avoid the operation or rejection of the circuit breaker, and the intelligent monitoring system of the operation loop of the circuit breaker is designed. The system improves the existing tripping/ closing circuit, and gives the selection and parameter setting of the components in the system, and can realize the full working condition monitoring and protection of the tripping/ closing circuit. In ord to monitor that state of the circuit board of the circuit breaker and protect the outlet contact of the circuit breaker in real time, the fault alarm of the press plate mis-operation and the protection of the outlet contact is realized, the system adopts a method of using the inductive proximity switch and the Hall voltage sensor, and the specific installation position of the sensor is given. The system adopts single-chip computer to process and upload the on-site information collected by the sensor, and the background software interface is written by using LabVIEW, and the functions of real-time state display, man-machine interaction, historical data storage and fault alarm can be realized.
