摘要
小电流接地系统最常见的故障是单相接地故障。选线装置的硬件电路主要有采样模块、主控制模块及人机接口模块三个部分组成,分别采用32位ARM Cortex-M3 STM32f2和8位STM8S207S8微控制器芯片作为采样模块、主控制模块、人机接口模块的核心控制单元。选线装置的软件程序主要有主控制模块程序、人机接口模块程序、定时采样子程序、故障判断子程序等。现场运行结果表明,该装置运行稳定,能够正确地快速选线。
The most common failure of non-effectively groundedsystem is the single-phase-to-ground fault. The hardware circuitof the line selection device is mainly composed of such threeparts as sampling module, main control module and hu-man-computer interface module, respectively using 32-bit ARMCortex -M3 STM32f2 and 8-bit STM8S207S8 microcontrollerchips as the core control units of the three parts. The softwareprogram of the line selection device mainly consists of main con-trol module program, human-machine interface module program,timing sampling subroutine, fault judgment subroutine and so on.Field operation results show that the device is stable and can re-alize fast and correct line selection.
