摘要
用于广播和通信的信息车除对人身安全有要求外,对不间断供电和抗电磁干扰等都有很高的要求,为此车内通常采用IT系统或电气分隔措施配电。根据有关国际电工标准对信息车电气设计和安装作一简介。
Except for the requirements on personal safety, the communication vehicle for broadcast and communication has higher demand for the uninterruptable power supply and anti-electromagnetic interference. Therefore, IT system or electrical separation measures are used for power distribution in the vehicle. The paper introduces the electrical design and installation of communication vehicle in accordance with IEC.
