| 摘 要： | 目前,电力工程接地网设计中仍大量使用降阻剂作为主要的降阻措施。文章从降阻剂的降阻原理入手,分析计算降阻剂在不同大小接地网的降阻效率。通过计算分析表明,在线路杆塔接地网等小型接地网中,使用降阻剂可达较好的降阻作用;而在大中型变电站接地网中的水平接地网中敷设降阻剂则无法有效降低接地网的接地电阻,因此,不应把水平接地网敷设降阻剂作为主要降阻措施。

| Abstract: | Resistance reducer is still used in large scale as the main restistance-diminshing measure in the design of earth mat of electric projects now.Beginning with the principle of resistance reducer,the article analyzes and calculated the resistance -diminishing efficiency in earth mats of different sizes.The calculation and analysis shows that resistance reducer have a better effect in small earth mats like those of towers of transmission line.However,it can not effectively reduce the resistance of the horizontal earth mats in transmission substation of large and middle sizes.So the resistance reducer in horizontal earth mats should not be used as the main measure to reduce resistance. |
