摘要
屏蔽电缆抑制干扰的能力除与屏蔽层本身的质量有关外,还与屏蔽层接地方法密切相关。提出良好的屏蔽,仅靠电缆屏蔽层是不够的,重要的是选择正确的屏蔽层接地方式、接地点数和接地位置。正确使用屏蔽和良好的接地则是使系统稳定运行、消除干扰的重要措施。着重阐述了电缆屏蔽层接地方式及其抗干扰分析,对工程应用具有实用价值和指导意义。
The ability of restrain disturbance in shielded cable is correlated with the quality of cable shielding Line and the grounding methods. Point out that good shielding only rely on cable shield is not enough, it needs correct shield grounding methods, grounding points and grounding position. Right shielding and good grounding is important means to stabilize work of system and to obviate the disturbance. This paper describes several grounding methods and corresponding anti-in- terference analysis of cable shielding line,which has practicality and instructional significance for engineering application.
