因(yin)地(di)制(zhi)宜地(di)設計(ji)(ji)方(fang)案，通常(chang)防雷接(jie)(jie)(jie)地(di)的電(dian)(dian)(dian)(dian)阻(zu)(zu)要(yao)求(qiu)不(bu)超過(guo)10歐(ou)(ou)姆，有(you)些電(dian)(dian)(dian)(dian)子設備(bei)的接(jie)(jie)(jie)地(di)系統要(yao)求(qiu)達到4歐(ou)(ou)姆或1歐(ou)(ou)姆的接(jie)(jie)(jie)地(di)電(dian)(dian)(dian)(dian)阻(zu)(zu)。這里(li)常(chang)常(chang)有(you)個誤區(qu)，認為(wei)(wei)只(zhi)要(yao)有(you)了(le)10歐(ou)(ou)姆，4歐(ou)(ou)姆或1歐(ou)(ou)姆的接(jie)(jie)(jie)地(di)電(dian)(dian)(dian)(dian)阻(zu)(zu)就滿足了(le)設計(ji)(ji)要(yao)求(qiu)，而忽(hu)略了(le)季節因(yin)素對接(jie)(jie)(jie)地(di)電(dian)(dian)(dian)(dian)阻(zu)(zu)的影響。因(yin)為(wei)(wei)土壤(rang)的電(dian)(dian)(dian)(dian)阻(zu)(zu)率(lv)是(shi)隨季節而變(bian)化的，規范所要(yao)求(qiu)的接(jie)(jie)(jie)地(di)電(dian)(dian)(dian)(dian)阻(zu)(zu)實際上是(shi)接(jie)(jie)(jie)地(di)電(dian)(dian)(dian)(dian)阻(zu)(zu)的最(zui)大允許值。

貴州防雷(lei)公(gong)司提及防雷(lei)接地(di)工(gong)程本身的特(te)點(dian)決定(ding)(ding)了(le)(le)周圍環境(jing)對工(gong)程效果決定(ding)(ding)性的影響，因(yin)此，脫離了(le)(le)工(gong)程所(suo)在(zai)地(di)的具體情(qing)況(kuang)來設計(ji)接地(di)工(gong)程是(shi)不可(ke)靠的。設計(ji)的好(hao)壞(huai)取決于(yu)對當地(di)土壤(rang)環境(jing)等諸多因(yin)素的綜合考慮，土壤(rang)電阻率，涂(tu)層結構，含水情(qing)況(kuang)，季節因(yin)素，氣候及可(ke)施工(gong)面積等因(yin)素決定(ding)(ding)了(le)(le)接地(di)網的形狀，大小及工(gong)藝材料的選擇(ze)。這些是(shi)在(zai)正式進(jin)行(xing)接地(di)設計(ji)前必須首先(xian)搜集好(hao)的資料。
