堆场和道路智能照明的节能与推广

阐述高压钠灯功率、亮度和寿命与电压的关系,分析能对电网电压波动快速响应,闭环自动稳压、可控平缓调压的智能装置的工作原理和节能模式,应用它在软启动和运行时,灯具电流几乎恒等于额定电流,因而,不仅可以大量节约电能,还可以延长灯具的使用寿命,并探讨它在集装箱堆场应用集中远程控制的方案。

Energy-saving of Intelligent Lighting for Yard and Road

The relation among the power efficiency,brightness,life service and the pressure of the high voltage sodium lamp are expounded.The analyses on the working principle and energy-saving mode of intelligent device such as the rapid response of energy to the voltage fluctuation of electric net,automatic stabilization of voltage of closed loop,controllable smooth slow adjustment of voltage.The current of intelligent lighting is almost equal to the rated one during the soft starting and operation.Thus it can not only save a large amount of energy,but also prolong the service life of the lamp.The centralized and remote control scheme for the container yard are also discussed.
