应用光电自动替续器不但可以减少人们的劳动,而且还能很准确地完成记录和警报的工作,因此在机床使用、轧钢机的保安、仓库的防盗警卫、产品计数、消防、灯塔信号灯开闭以及其他各种机器的控制等方面都能应用光电自动替续来管理。光电自动替续器在装配方法和线路上虽然各有不同,但其主要原理则一,不外是利用光电池、光电管、或光敏电阻来产生微弱的光电流(几十微安),再经过电子管放大后,将较强的电流通到电磁替续器上来完成替续的作用。我们为了丰富物理课的教学内容也试制了一个光电自动替续器。为了得到更稳定的效果起见,器内工作电流用的是直流电。虽然在按装上稍繁杂了一些,但可避免使用电池作电源的不便。经过多次试验和使用,效果很好,现在介绍出来供大家参考。
The use of photoelectric auto-renewal not only reduces people’s labor, but also records and alarms can be accurately completed, so the use of machine tools, rolling mill security, anti-theft security warehouses, product counting, fire, beacon beacon open As well as other kinds of machine control, etc. can be applied automatically to manage photovoltaic. Although there are differences in the assembly method and the circuit, the main principle of photoelectric auto-alternator is only that it uses the photocell, photocell or photo-resistor to generate weak photocurrent (dozens of microamps) Tube amplification, the stronger the current through the solenoid to continue to replace the role. In order to enrich the teaching contents of physics class, we also made a photoelectric auto-replacement device. In order to get a more stable effect, the working current within the device is DC. Although a little more complicated in the press, but to avoid the inconvenience of using batteries for power. After many tests and use, the effect is very good, now introduced for your reference.
