为了提高我国客车设备自动化水平,我们试制了两套铁路客车用无触点电扇自动控制装置,分别以客车的运行、停止或温度控制电扇的转与停。经过在西安—北京79/80次快车上的试验,动作可靠,既节约了用电,又免于人工操纵,受到广大旅客及乘务人员的欢迎。现将其原理分述于下。 In order to improve the automation level of passenger car equipment in our country, we have trial-produced two sets of automatic control devices for non-contact fans for railway passenger cars, respectively controlling the rotation and stopping of the fans by running, stopping or temperature controlling the passenger cars. After the Xi’an - Beijing 79/80 fast train test, reliable action, which not only saves electricity, but also from manual manipulation, by the majority of passengers and crew welcome. Now the principle is divided below.
