摘要
在行业标准CJJ49—92《地铁杂散电流腐蚀防护技术规程》中,地铁杂散电流的计算公式是在钢轨对地绝缘介质均匀条件下得出的,并且没有考虑结构钢和排流网等实际情况。对这些情况下的杂散电流分布进行分析,并考虑钢轨绝缘扣件的局部绝缘损坏情况。
In the professional standard CJJ 49--92 Code for Anti-corrosion of Stray Currents in Subways, the formula for stray current calculation was deducted under the condition of uniform medium of rail to earth insulation, without considering structure steel and current drainage net. The article analyzed the distribution of stray current under these conditions, taking into account the local insulation defect of rail fastenings.
