直流杂散电流干扰缓解方法及其适用性
Mitigation methods and their applicability for DC stray current interference
摘要
Abstract
Through indoor simulated experimental equipment, mitigation methods which contained the bond resistor method, gal-vanic anode method and metallic shield method were studied to mitigate DC stray current interference caused by the impressed current cathodic protection system on pipelines without cathodic protection at the external. The influences of bond resistance, galvanic anode location and materials, metallic shield location and connecting methods on the mitigation and regularity for different types of interfer-ence were investigated, and the applicability for different mitigation methods was also analyzed. In addition, it can also provide refer-ence for practical engineering with putting forward recommendations and application conditions for different types of interference.关键词
