道路照明中变压器的晶闸管调压方法的设计研究

Research on The Design of Transformer Voltage Regulating and Stabilizing System Controlled by SCR in Road Lighting

针对目前普遍采用的城市道路照明节能方案及高压钠灯的特点,将照明时间分为三时段:高峰期、正常、低峰期。每一时段对应不同工作电压,因此该文提出了基于单片机控制晶闸管,串接变压器调压稳压的实用方案,该方案调压范围宽,精度高且接线简单。将此方案用于高压钠灯的节能控制系统,通过实例分析证明其可行、有效。

A novel power-saving control system in road lighting is designed in this paper.According to the practical traffic in different period of time,the road lighting time is divided into high flow time,normal flow time and low flow time.Meanwhile each period represents different voltage.The transformer in series is used to regulate and stabilize the voltage of the high-pressure sodium lamp and is assembled by SCR that is controlled by the single chip.Finally,this method is proved feasible and effective through the experiment.
