描述
凡與大地有可靠接觸的金屬導(dǎo)體,除另有規(guī)定外均可作為自然接地體。如埋設(shè)在地下的金屬水管、井管等等。人工接地體通常采用直徑40~50mm的鋼管或40mm×40mm×4mm~50mm×50mm×5mm的角鋼垂直埋設(shè)。為兼顧成本與性能,長(zhǎng)度一般以2.5m左右為宜,數(shù)量不少于兩根。它們可以成排布置,也可作環(huán)形或射線形分布。無(wú)論是自然接地體還是人工接地體,安裝完后都需對(duì)接地電阻進(jìn)行測(cè)量,達(dá)標(biāo)方可投入使用。把自來(lái)水管作接地體或“插根鐵絲當(dāng)?shù)鼐€”是不符合要求的,也是很危險(xiǎn)的。
