锅炉炉膛火焰电视系统信号传输方式浅谈

Discuss on Signal Transmission Mode of Boiler Furnace Flame Television System

锅炉炉膛火焰电视系统是电站锅炉常规配备系统,随着机组容量的增大,集控室位置离现场设备越来越远,信号传输所使用的电缆也越来越长,既增加了工程成本,也增大信号衰减和受干扰的可能性。随着光传输技术的成熟,光纤成本降低,可将信号采用光缆传输(控制信号与视频信号),既节省成本,又提高了信号传输的可靠性,电缆连接变得更简洁。

Boiler furnace flame television system is a conventional equipment system for power plant boilers.With the increase of power plant capacity,the location of the CCR is farther and farther from the field equipment,and the cable used for signal transmission is longer and longer,which not only increases the engineering cost,but also increases the possibility of signal attenuation/interference.With the maturity of optical transmission technology, the cost of optical fiber is reduced.The signal can be transmitted by optical cable(control signal and video signal),which not only saves cost,but also increases the reliability of signal transmission,and simplifies cable laying.
