摘要
为了提高井下低压电网选择性漏电保护的可靠性,通过故障参数特征及影响因素综合分析,以AVR单片机为核心进行了硬件和软件设计,克服传统设计不完整,电磁兼容性差,灵敏度低的缺陷,通过矿井低压电网选择性漏电保护运行,证明装置具有较高的可靠性,有利于提高矿井低压电网供电安全性,保证矿井安全生产。
In order to raise the reliability of selective leakage protection of low-pressure electric network, hardward and software design is carried out with AVR single-chip computer as its core through the comprehensive analysis of failure parameter characteristics and influencing factors.The design overcomes the defects of incompleteness of poor electromagnetic compatibility and low sensitivity of the traditional design. Through the operation of selective leakage protection of low-pressure electric network in the mine, it is proved that this device has high reliability, greatly raising the safety of low-pressure network electricity supply in the mine and ensuring safe production.
