dcs系統(tǒng)接地材料及要求
(1)接地體與接地網(wǎng)干線的材料要求接地體和接地網(wǎng)干線所用鋼材規(guī)格可按下表選用,若接地電阻滿足不了要求時(shí),也可選用銅材。如果接地體和接地網(wǎng)干線安裝在腐蝕性較強(qiáng)的場(chǎng)所,應(yīng)根據(jù)腐蝕的性質(zhì)采取熱鍍鋅、熱鍍錫等防腐措施或適當(dāng)加大截面。
(2)接地連線要求dcs系統(tǒng)的保護(hù)地和屏蔽地連線應(yīng)使用銅芯絕緣電線或電纜連接到電氣專用接地網(wǎng)或接地體上。當(dāng)接地連線距離較長(zhǎng)、dcs系統(tǒng)對(duì)接地電阻要求較高或接地干線分接的支線數(shù)量較多時(shí),宜選用表中截面較大的電線電纜。、、
