随着水电站机组容量和体积的增大,机组台数增多,大型水电厂的主厂房(主机室)愈来愈高大宽敞。解决好高厂房大面积的照明问题,不仅能够给机组安全运行、维修提供良好的工作条件,而且能够节约照明耗能,减少照明灯具的维护费用和维护工作量。所以,已逐步引起了运行单位的重视。 With the increase of unit capacity and volume of hydropower station, the number of generating units has increased, and the main plant (host room) of large hydropower plants has been getting taller and more spacious. Solve the problem of lighting a large area of ​​a large plant, not only to the unit safe operation and maintenance to provide good working conditions, but also to save lighting energy consumption and reduce lighting maintenance costs and maintenance workload. Therefore, it has gradually aroused the attention of operating units.
