摘要
供配电系统是广播电视发射台可靠运行的关键支撑,必须保证其安全稳定运行,并符合供电的相关要求。基于《广播电视安全播出标准》中关于无线发射台的规范要求和广播电视发射台建设实际情况,讨论如何优化发射台供配电设计。该方案包含高低压供变电、控制方式、电源防雷、故障预防以及系统维护等内容,对完善广播电视发射台建设和确保发射台供配电系统正常运行具有重要的借鉴意义。
Power supply and distribution system is the key support for reliable operation of radio and television transmitting station,and it must ensure its safety and stability during operation and meet the relevant requirements of power supply.Based on“the standard of safe broadcasting of radio and television”,the paper discusses how to optimize the design of power supply and distribution of the transmitter.The scheme includes high and low voltage power supply and transformation,control mode,power supply lightning protection,fault prevention and system maintenance,which is of great significance for improving the construction of radio and television transmission station and ensuring the normal operation of the transmission station power supply and distribution system.
