廠用/配電中壓開關(guān)柜為全廠輔機(jī)/供電系統(tǒng)的供電樞紐。在發(fā)生內(nèi)部故障時(shí)，是否能迅速地切除故障，對(duì)全廠/配電系統(tǒng)的安全運(yùn)行至關(guān)重要。但是，按目前的保護(hù)方案，存在以下幾個(gè)問題： </p> <p> ① 中壓母線尚沒有配置任何專門的保護(hù); 而是由進(jìn)線開關(guān)的相關(guān)后備保護(hù)來兼顧的; </p> <p> ② 進(jìn)線開關(guān)與出線開關(guān)的保護(hù)需要相互配合:一般速斷保護(hù)延時(shí)的級(jí)差至少為300ms，甚至500ms ; </p> <p> ③ 過流保護(hù)的配合級(jí)差更是長(zhǎng)達(dá)1 – 2秒。 </p> <p> 所以，廠用/配電系統(tǒng)中壓母線上所發(fā)生的任何故障都至少要延時(shí)切除。換句話說，現(xiàn)有的廠用中壓母線能在**早時(shí)間切除故障的保護(hù)還是個(gè)空白。可是，我們只要稍加注意，就會(huì)不難發(fā)現(xiàn)不論是中壓開關(guān)母線的上游還是下游的諸多電氣設(shè)備無一沒有配有快速保護(hù)。相比之下，我們恐怕很難有充分的理由來說明，中壓母線的安全性可靠性應(yīng)該受到這樣的懈怠。鑒于中壓母線的重要地位，任何故障的延時(shí)切除，都是我們極為不愿意看到的狀況。因?yàn)殚_關(guān)柜內(nèi)的各種故障，其短路電流所產(chǎn)生的電弧及其大量的高溫，使柜內(nèi)氣體急劇膨脹，可在極短的時(shí)間內(nèi)達(dá)到頂峰，嚴(yán)重危及人身和設(shè)備安全。
