6kV高压开关柜通信线路的改进

摘要

Aimed at improving stability and anti-jamming capability of 6kV high voltage switchchgear communication systems, 485 special cable is used, hand in hand topological structure is selected as bus network, communication cables are taken single-point grounding, wiring is avoided power lines in parallel. After the implementation of the program the reliability and real time of communication are advanced.%为了提高变电站6kV高压开关柜通信系统的稳定性和抗干扰能力,选用485通信专用线缆,总线网络选择手牵手拓扑结构,通信线缆采用单点接地方式,布线避免与大功率电力线平行。该方案实施后通信系统的可靠性、实时性得到了有效改善。
