摘要
电缆屏蔽层接地是抑制干扰信号的重要手段，是维持系统稳定运行的重要措施。其抑制干扰的能力除与屏蔽层本身质量有关外，还与屏蔽层接地方法密切相关。良好的屏蔽需选择正确的屏蔽层接地方式、接地点数及接地位置。
The cable shield grounding is an important means in restraining signal disturbance and critical measures to sustain stable running. The ability of restraining disturbance is correlated with the method of shield grounding except the quality of cable shield. Point out that good shielding needs correct shield grounding method, grounding points and position.
