從布線工程角度考慮,由于連接電纜存在分布電容和分布電感,使連接電纜成為儲(chǔ)能元件。它們?cè)趥鬏敳豢杀苊獾卮鎯?chǔ)能量,一旦當(dāng)線路出現(xiàn)開(kāi)路或短路時(shí),這些儲(chǔ)能就會(huì)以電火花或熱效應(yīng)的形式釋放出來(lái),影響的本安性能。因此既要保證連接傳輸電纜不會(huì)受到外界電磁場(chǎng)影響及與其他回路混觸,又要布線長(zhǎng)度和感應(yīng)電動(dòng)勢(shì)所帶來(lái)的附加非本安能量,依此來(lái)確定電纜的允許分布電容和允許分布電感,各防爆檢驗(yàn)機(jī)構(gòu)主要采取以集中參數(shù)的考慮電纜分布參數(shù)的。
