浅谈广电行业总前端机房动力系统

On the Power System of the Front-end Room in the Broadcasting and TV Industry

广电行业的总前端机房供电系统支撑承载数字电视业务、数字电视增值业务和互联网等业务的A级机房正常运行,该供电系统是数字电视信号能够连续、安全、平稳发出的重要保障。结合了北方广电辽宁有线总前端机房的供电系统,分析了总前端机房供电系统的结构,主要包括外部输入电源模块、高低压供配电模块、不间断电源(UPS)模块、自备电源模块、机房机柜供电模块、电力监控模块、机房接地模块等。

The power system of the frontend Room in the Broadcasting and TV Industry supportsthe normaloperation ofthe Alevel computerroom which bears the operation of the digital TV service, digital TV valueadded service and the Internet and the power supply system is an important guarantee for the continuous, safeand stable digital TV signal emitting. Combined with the power system of the frontend Room in the NorthernLiaoning Broadcasting and TV Industry, this paper analyzes the structure of the frontend computer room powersupply system including the external input power supply module, high and low voltage power supply module,uninterruptible power supply （UPS）module, selfprovided power supply module, power supply module ofcomputer room and cabinet, electric management control module andgrounding module.
