摘要
为防止煤矿地面供电电网因老化导致电网安全性能降低,进一步提高地面供电系统的稳定性,保证煤矿供电安全,通过技术研究对原电网进行优化改进,决定对地面供电系统加装DZ24L型漏电断路器,对其动作电流值进行合理确定,并提出了若干项漏电断路器安装维护技术要求。通过优化改进后,大大提高了电网供电效率,降低了供电电网故障率,具有显著的推广意义。
In order to prevent the deterioration of the safety performance of the power grid caused by the aging of the ground power supply network in coal mines,further improve the stability of the ground power supply system, and ensure the safety of the power supply in coal mines, the original power grid was optimized and improved through technical research. It was decided to install dz24 l leakage circuit breaker in the ground power supply system, reasonably determine its action current value, and put forward several installation dimensions of the leakage circuit breaker Technical requirements for protection. After optimization and improvement, the power supply efficiency of the power grid is greatly improved and the failure rate of the power grid is reduced.
