摘要 煤矿是我国能源产业的重要组成部分,但由于井下环境的特殊性,导致漏电事故频发,给矿工生命财产安全带来严重威胁。因此,设计一种可靠的煤矿井下电网漏电保护系统对于提高煤矿安全生产水平具有重要意义。文章基于现场总线技术,针对煤矿井下电网漏电保护需求,设计了一种可行的系统方案,通过对煤矿井下电网的特点和漏电保护原理进行研究,确定系统的功能需求和性能指标。选取适合井下环境的传感器和执行器,设计相应的硬件电路,利用现场总线技术实现传感器和执行器间的数据通信。研究结果表明,基于现场总线的煤矿井下电网漏电保护系统具有较高的实用价值,不仅能及时检测电网漏电情况,还能通过独立控制器实时监测井下电网的运行状态。因此,在煤矿井下电网安全方面,该系统具有重要的应用前景。 Coal mines are an important component of China’s energy industry,but due to the special nature of the underground environment,power grid leakage accidents occur frequently,posing a serious threat to the safety of miners’lives and property.Therefore,designing a reliable underground power grid leakage protection system for coal mines is of great significance for improving the level of coal mine safety production.This article is based on fieldbus technology and designs a feasible system solution for the leakage protection needs of underground coal mine power grids.By studying the characteristics and leakage protection principles of underground coal mine power grids,the functional requirements and performance indicators of the system are determined.Select sensors and actuators suitable for the underground environment,design corresponding hardware circuits,and use fieldbus technology to achieve data communication between sensors and actuators.The research results of this article indicate that the leakage protection system for coal mine underground power grid based on fieldbus has high practical value.It can not only timely detect the leakage situation of the power grid,but also monitor the operation status of the underground power grid in real time through an independent controller.Therefore,this system has important application prospects in the safety of underground power grids in coal mines.
