随着有线电视网络的不断发展,有线电视设备无论是干线还是支线,其使用量不断地增加,而其对雷电的防护设施不相适应,况且夏天将至,本市县雷雨天频发,有线电视设备又要经历一次严峻的考验,所以有线电视设备的防雷刻不容缓。本文针对避雷这一问题,通过接地线的改造,以及对防雷设备的改造,提出了一些独创性设计思路并实践应用于有线电视网络系统。
With the continuous development of cable television networks, cable television equipment, whether it is trunk or branch line, its use continues to increase, and its lightning protection facilities do not meet, and the summer is approaching, the county thunderstorm sky frequent, wired TV equipment has to undergo a severe test, so cable TV equipment lightning protection without delay. In this paper, aiming at the problem of lightning protection, this paper puts forward some original design ideas and applies it to the CATV network system through the modification of the grounding line and the transformation of the lightning protection equipment.
