当前,我国煤矿井下安装使用煤矿安全检测及监控系统逐渐增多。煤矿安全检测及监控设备的安装使用,保证了安全生产,促进了煤炭工业现代化的发展。为了使煤矿安全检测监控设备正常运转,充分发挥效益,必须避免在安装中出现故障。对系统中甲烷的测量、报警,特别是断电控制中被控机构是馈电开关 DW 系列的,更应注意防止供电
At present, China’s coal mine safety monitoring and installation of coal mine monitoring system is gradually increasing. Coal mine safety testing and monitoring equipment installation and use, to ensure safety in production, and promote the development of coal industry modernization. In order to ensure the normal operation of coal mine safety monitoring equipment, give full play to the benefits, we must avoid failure in the installation. The measurement of methane in the system, the police, especially in the power-off control of the controlled agency is the feed switch DW series, but should pay attention to prevent power supply
