| 摘 要： | 为解决高压输电线路附近民房由于工频电场而产生感应电压的现象,提出采用接地金属网来减小民房内工频电场强度以及居民房内不良接地导体的感应电压。采用高密度板制做的木盒子模拟居民房,分别在人工气候室内和湖南省内某500 kV和220 kV交流输电线路下方进行试验,并采用CDEGS电磁计算软件进行计算,试验结果与计算结果表明,接地金属网可有效减小高压输电线路周围居民房中的工频电场强度和感应电压。

| Abstract: | To mitigate the phenomena of induced voltage in residential buildings near to HV power transmission line due to power frequency electric field,it is proposed to decrease the power frequency electric filed intensity inside residential buildings as well as the induced votlage on the badly grounded conductros in residential buildings by metal ground mesh.Simulating residential buildings by the boxes made of high density wood-based panels,the experiments are performed in the phytotron and in a certain place und... |
