摘要
针对煤矿井下127V低压照明电路环境复杂、故障频发等特点,研究其各种数字化保护电路,以增加保护系统的可靠性,并通过PLC控制,克服了单片机系统和普通显示器抗干扰性能差的缺点。
In the light of the features of underground coal mine such as the environmental complexi 127 V low-voltage illuminating protection system equipper in ty, frequent occurrence of faults, etc., this paper researches various digital protective circuits for increasing the reliability of the protective system and overcoming the disadvantages of the poor antijamming performance of the monolithic system and common monitor through PLC.
