摘要
本文通过对一起典型电缆击穿事故的分析，引出单相电缆或绝缘线运行时产生的交变磁通对磁场中的铁附件产生涡流效应，事故引起铁附件发热，造成电缆或绝缘线绝缘损坏击穿的问题，并对预防涡流发热提出了预防措施。
Based on a typical cable breakdown analysis of the accident, leads to single - phase cable or insulated wire running produced alternating magnetic flux of the magnetic field produces ed- dy current effect of iron accessories, iron accessories accident caused by heat, causing the cable or insulated wire damaged insulation breakdown problems, and to prevent eddy current heating and recommending preventive measures.
