摘要
分析了浪涌能量分布特性,据此确定了浪涌辐射骚扰测量频率最高值为1MHz。采用频谱分析仪在煤矿井下中央水泵房对水泵电机启停过程中电磁噪声进行测量。测量和分析结果表明,浪涌对煤矿井下水泵房电磁环境有一定的影响,其产生电磁辐射不会影响人体健康,但会影响矿井下的监控、通信和控制系统正常工作。
Energy distribution characteristic of the surge was analyzed, and the frequency of surge under radiated dis- turbance was measured and the maximum was 1 MHz. Spectrum analyzer was used to measure electromagnetic noises in the center pump house during the motor start and stop. The results show that the surge has an influence to electro- magnetic radiation environment in mine pump house. The electromagnetic radiation has no hazardous effects to human body, but can affect the function of supervision equipments, communication and control systems.
