摘　　要：针对目前低压中性点不接地系统漏电保护装置存在的缺陷,提出了一种集中控制模式与零序电流相对比幅法、零序电流方向法和零序电流群体比幅比相法相结合的漏电判断方法;通过改进传统的漏电保护算法,提高了漏电判断的准确性;设计了基于ARM处理器STM32F103ZET6为核心的新型低压选择性漏电保护装置。实验表明,该新型漏电保护装置能够可靠、快速地实现漏电保护,提高了电网的稳定性。Aiming at the problems exiting in protection system of low-voltage distribution network in coalmine,a centralized control method and several leakage judge algorithms were put forward.Upon improving the traditional leakage protection algorithms,the accuracy of leakage judging was improved.Based on the ARM core of STM32 processor,a new selective leakage protective device was studied and designed.It had been demonstrated the device responded fast and reliably which improved the stability of the power network.
