在机场助航灯光系统中,调光器是重要的设备,但是在运行过程中会产生较大的谐波,导致系统电压、电流出现畸变,整个功率因数降低,甚至产生设备损坏的情况。文章首先分析了机场助航灯光系统谐波,通过对调光器的研究分析,提出正弦波恒流调光器应用方案,能够减小谐波含量,维护机场助航灯光系统的正常运行。
Dimmer is an important equipment in the airport navigation lighting system, however, it will generate larger harmonics during operation, resulting in system voltage and current distortion, the entire power factor is reduced, and even equipment damage occurs. Firstly, the paper analyzes the harmonic of the lighting system of the airport’s aids to navigation, and proposes the application scheme of the sine wave constant current dimmer through the research and analysis of the dimmer, which can reduce the harmonic content and maintain the normal operation of the airport lighting system.
