控制电缆屏蔽层接地方式探讨

Inquire into Shielded Grounding Mode of Control Cable

介绍了发电厂控制系统中,采用屏蔽型控制电缆抑制电磁干扰(EMl)的重要措施。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、接地点数和接地点位置。

It adopted important measure of using shield cable to restrain electromagnetic interference,and point out that good shielding.only rely on cable shield is not enough,it needs correct shield grounding mode grounding points and grounding position.
