呼和浩特铁路局在包头西等站,推广应用金属卤化物新光源新灯具,及光电控制电灯开关。由于新型开关的采用,避免了早开晚关及长明灯而造成的浪费。其原理:光线照射光导管,亮度强到一定值,产生电流,使控制器工作而断电,照明灯即熄灭;光线照射光导管,亮度弱到一定值,光电控制器停止工作而继
Hohhot Railway Bureau promotes the use of new metal halide source lamps and photoelectric control of light switches at Baotou West Station. Due to the adoption of the new switch, the waste caused by early opening, late closing, and long lighting is avoided. Its principle: light irradiates the light pipe, the brightness is strong to a certain value, produces the electric current, causes the controller to work and turns off, the illumination lamp extinguishes; The light irradiates the light guide tube, the brightness is weak to a certain value, the photoelectric controller stops working and continues
