因工作繁忙,我们使用的“TUR”D350型双台面 X 线机,透视后常忘关闭。使之长时间处于空负荷状态,影响 X 线机各部件的使用寿命。为此我们设计安装了 X 线机透视台空载延时自动断电装置.经两年多的使用效果较好,现介绍如下。工作原理:当 X 线机控制台技术选择开关位于“Ⅰ”台(透视台)位置时,“Ⅱ”台的中间继电器(SJ)不工作,其静接点常闭。按下“K_1”,QJ 得电接通 SJ_(11)线路。使 M 启动延时开始。假如开机后透视一直不进行,待达到延时限定时间后,由 M 断开
Due to busy work, we use the “TUR” D350 double table X-ray machine, often forget to turn off after the perspective. So that for a long time in the state of empty load, affecting the life of X-ray machine components. To this end, we designed and installed the X-ray machine X-ray transmission delay automatic power-off device. After two years of better results, are presented below. How it works: When the X-ray machine console technology selector switch is located in the “I” station (fluoroscopy station) position, “Ⅱ” station relay (SJ) does not work, the static contact normally closed. Press “K_1” and QJ will power on the SJ_ (11) line. M start delay to start. If the boot has not been conducted after the start, to be delayed after the time limit, by the M off
