摘要
为实现对开关柜内部局部放电的带电检测并保证其检测结果准确,提出了一种将超声波法(AE)与暂态对地电压法(TEV)相结合的同步联合检测方法,并研制了检测装置。该装置前端采用12位的ADS805模数转换器,主控部分采取FPGA+ARM的结构来实现,数据处理部分采用i MX257为核心,不但提高了检测系统的可靠性,并且具有丰富的人机交互界面。
To achieve the conduct live detection of partial discharge in power distribution cabinet and guarantee the detection result correct, the paper provides a method combining AE with TEV and develops the detection device. The device adopts 12 bit ADS805 converter module, the main control part adopts the structure of FPGA＋ARM implementation, and the data processing part uses iMX257. All of these increase reliability of the detection system and realize rich HMI.
