摘要
讨论了电力线载波设备与高频通道配合时需注意的事项，通过计算推导出来电力载波设备在接入通道或负载两种状态下电平差值的计算公式，并提出了在电力线载波设备接入高频通道时需注意的问题，为实际工程中电力线载波使用提供帮助。
The paper discusses the issues for attention by a combination of power line carrier wave and high frequency channel and derives level difference calculation equation by calculating in two conditions from power line carrier equipment access to the channel to loading. It is proposed that concerned problems as power line carrier wave accessing to high frequency channel, which may provide help for using high frequency channel.
