摘要
针对煤矿越级跳闸事故频发给煤矿生产造成严重影响的问题,设计了一种基于C8051F020单片机的微控制器。它是采用反向闭锁式纵联差动保护原理的防越级跳闸继电保护装置,具有通信方式简单、功能齐全、性价比高等优点。该装置经调试动作灵敏、可靠性强,能有效防止煤矿越级跳闸事故的发生,可广泛适用于井下短距离的供电系统中。
The mine anti-jumping trip accident happens frequently, which seriously impacts on production. Based on C8051F020 SCM, designs one anti-jumping trip relay protection device using reverse blocking type longitudinal differential protection principle. This device has the advantages of simple communication, full function modes and better comprehensive performance. After debugging, the action is sensitive and reliable, and can prevent the occurrence of mine anti-jumping trip accidents effectively. So, it can be widely used at underground mine power supply system in short distance.
