摘要
高压钠灯广泛应用于各种公共场所的照明,其受电压暂降影响会闪烁或熄灭,旨在对高压钠灯的工作原理和特性进行系统分析,并深入探讨其在工作状态下受到电压暂降时电参数的变化。利用自开发的电压暂降发生器建立相关测试平台,重点对高压钠灯在最敏感相角下的不同暂降幅值和不同暂降持续时间的特性表现进行研究;基于试验数据绘制出钠灯电压敏感度曲线,能更直观地表现出钠灯的正常工作范围。
High pressure sodium lamp is widely used in various public lighting, it affected by voltage sag will blink or extinguished, the working principle and characteristics of high pressure sodium lamp(HPSL) are analyzed systematically, and the changes of the HPSL's electrical parameters which are affected by voltage sag when it is working are discussed. Using the voltage sag generator developed by ourselves to establish a test platform to focus on the characteristics and performance of the HPSL under different voltage sag amplitude value and duration at the most sensitive phase angle. Based on the test data, the voltage sensitivity curve of the sodium lamp is produced, which demonstrates more directly the normal operating range of the sodium lamp.
