摘要
对电气设备表面局部放电闪络产生的紫外光辐射进行在线监测,可以有效地预防电力系统的事故发生,对电力系统、电厂以及中低压开关柜等的稳定可靠运行提供了重要保障。设计了一种微光安全监测预警系统,该系统主要包括传感器模块、信号采集模块、数据传输与存储模块、上位机软件等。在强电磁干扰环境下提取局部放电微光信号,利用光电转换信号放大模块转为电信号,通过ARM9以及GPRS模块把采集的数据上送至手机端或上位机软件,实现实时在线监测预警的功能。
On-line monitoring of the UV radiation from the partial discharge flashover of the electrical equipment in the power system can effectively prevent the accident of the power system,which provides an important guarantee for the stable and reliable operation of the power system,power plants and medium and low voltage switch cabinet. A glint security monitoring and early warning system was designed. It included sensor module,signal acquisition module,data transmission and storage module and software in PC. The optical signal in the strong electromagnetic interference environment was converted into an electrical signal via a photoelectric conversion signal amplification module. The collected data was transmitted to the mobile terminal or the software in PC through the ARM9 and GPRS,which can realize real-time online monitoring and early warning function.
