摘要
本文简述了地铁工程建成之后，对有害杂散电流进行及时有效防护的重要性，并着重提出一种可以对杂散电流进行自动补偿抵消的积极防护方案。该方案业已在２ｋｍ地铁供电系统的物理模型上进行了实验，结果表明，其防护原理正确，效果显著。
The importance to protect from the harmful stray current timly and efficientlyis briefly introduced in this pater,and an active protecting scheme that can cancel the straycurrent automatically is posed emphatically. Using a physical model of 2km undergroundelectical power system,An experienment is made with this scheme. The result shows thatits protecting principle is correct and the effect is obvious.
