随着我国城市建设的快速发展,城市高压电力隧道越来越多,电力维护人员逐步从输电线路维护改为地下电缆隧道维护。然而,地下电缆隧道在长期封闭,无人值守,日积月累,隧道内部产生了许多有毒、有害气体,针对这一问题,研制了一种电缆隧道有害气体监测系统,按照分层分布式设计,并采用催化燃烧式传感器监测现场有害气体浓度,能够有效地对隧道有害气体进行在线监测,保护隧道维护人员的健康,提升电缆隧道的维护管理水平。
With the rapid development of urban construction in our country, more and more urban high-voltage power tunnels are being built. Power maintenance personnel gradually change from maintenance of transmission lines to maintenance of underground cable tunnels. However, in the long-term closed, unattended underground cable tunnels, over time, there are many toxic and harmful gases inside the tunnel. To solve this problem, a cable tunnel harmful gas monitoring system has been developed. According to the hierarchical distributed design, Catalytic combustion sensors to monitor the concentration of harmful gases in the field can effectively monitor harmful gases in tunnels on the line, protect the health of tunnel maintenance personnel and improve the maintenance and management of cable tunnels.
