为了提高工作效率,定时自动开启电热蜡锅,我们自制了一台使用双向可控硅的定时开启装置。一、定时部分:焊下理疗科常用定时钟分针上的接触铜片,改焊于时针。引出闹铃时产生的交流电做为控制信号,这样就可将一小时内任意定时改为12小时内任意定时。二、双向可控硅电路部分: 由定时钟来的控制信号经Q_1整流加在继电器J_2线圈上,J_2触点吸合,6V交流电压经Q_2整流加在J_1线圈上,J_1动作,J_(1-2)接通双 In order to improve work efficiency, the timer automatically turn on the heating wax pot, we made a self-timer using the triac open device. First, the timing part: Welded under the physiotherapy department commonly used on the minute hand contact bronze, welding on the hour hand. The resulting AC out of the alarm as a control signal, so that any one hour within one hour can be changed to any timing within 12 hours. Second, the two-way thyristor circuit: the control signal from the clock to the relay J_2 by the rectification plus J_2 coil, J_2 contact pull-in, 6V AC voltage by Q_2 rectified plus J_1 coil, J_1 action, J_ (1 -2) connected to double
