前后导标系采用1000瓦和500瓦白炽灯泡,闪光是利用同步电机带动凸轮,常常因为火花太大烧坏接点而发生故障,同时火花造成对电网冲击,使同电网收音机产生干扰噪音,政治影响很大。为此,航标队首次用交流可控硅元件实行无接点控制,克服了缺点,防止了干扰,同时设计试验成功自动焕灯泡装置,确保导标的安全导航。

Front and rear guide system with 1000-watt and 500-watt incandescent bulbs, flash is the use of synchronous motor-driven cam, often because the spark is too large and burned contacts, and sparks caused by the impact on the grid, the same network radio interfere with the noise, political influence Great. To this end, the AAC team for the first time with the exchange of SCR components without contact control, to overcome the shortcomings, to prevent interference, while design and test the success of automatic Huan bulb device to ensure the guidance of the safe navigation.
