工程师对值机员小张和小王讲解电视发射机的电控部分。工程师:今天讲10kW发射机的电控部分,有关内容你们理解得怎样了? 张:电控部分的说明书和图纸太多,工作原理不容易弄清楚,看了好几遍也没有理出头绪,我感到这是电视发射机中比较难懂的部分。工程师:电控系统是整个发射机的指挥机构。主要有两大部份,即逻辑控制系统与交流配电系统。正是通过它们来实现对发射管灯丝电压、栅偏压、板极电压和帘栅压的控制和对
Engineers Xiao Zhang and Xiao Wang on the value of the television transmitter to explain the electronic control part. Engineer: Today about 10kW transmitter electronic control part, the content you understand how? Zhang: Electrical control part of the manual and drawings too much, the working principle is not easy to figure out, read several times did not figure out the clue, I Feel that this is the more difficult part of the television transmitter. Engineer: Electronic control system is the transmitter of the command body. There are two major parts, namely logic control system and AC power distribution system. It is through them to achieve the control of the firing tube filament voltage, gate bias, plate voltage and screen voltage control and
