摘要
灯具是电压敏感型负载,当电网电压突然跌落或者断电后,灯可能会熄灭,而气体放电灯为冷态启动光源,灯熄灭后重启需要十几分钟,本文对典型的几种光源进行抗电压跌落实验,研究在电网电压不同跌落幅值和跌落相角时灯具是否熄灭,并针对HID灯提出抗电压跌落的补偿方法。
Lamps are sensitive to the grid voltage, it may be extinguished when the grid voltage drops or cut off. The restart for gas discharge lamps will take more than ten minutes due to their cold start features. In this paper, several typical light sources are selected for voltage drop test, to study whether the lamps are extinguished under various voltage drop amplitude and phase angle. And then we present a compensate method for HID lamps to avoid their extinguish under voltage drop.
