摘要
通过实测一起220 kV输电线路下方居民生活区存在感应电压,结合理论分析和实测数据,发现感应电压产生的根本原因为金属物件未接地或存在接地不良的现象。针对线路下方出现感应电的情况提出了改造措施,并对居民住户生活区存在感应电压的部位进行了改造,改造后经实测发现感应电消除,改造方案达到了预期的效果。
Through the measured with a 220 kV transmission lines in residential areas are below the induction voltage, combined with theoretical analysis and experimental data, found that the fundamental reason for the voltage induced was metal objects or ungrounded ground bad phenomenon. The line appears below the induction electric situation puts forward improvement measures, and the existence of induced voltage on residents living area for part of the transformation, after the transformation of the measured found induction elimination scheme to achieve the desired results.
