對(duì)于中低壓開(kāi)關(guān)柜來(lái)講，以**快的速度切除故障意味著比較大限度地限制電弧燃燒釋放的能量，其益處是：1）保護(hù)附近工作人員免受電弧故障效應(yīng)的傷害；2）開(kāi)關(guān)柜內(nèi)部部件的限制到**??；3）很大減少開(kāi)關(guān)設(shè)備損壞的維修費(fèi)用；4）比較大限度地減少用戶停電時(shí)間，可盡快恢復(fù)生產(chǎn)；5）對(duì)于使用年限很長(zhǎng)需要進(jìn)行改造的開(kāi)關(guān)柜，采用電弧光保護(hù)可有效延長(zhǎng)其使用壽命，從而減少對(duì)開(kāi)關(guān)設(shè)備的投資費(fèi)用。 </p> <p> 電弧光保護(hù)作為中低壓母線保護(hù)，對(duì)配電系統(tǒng)還將提供以下益處：1）保護(hù)昂貴的主變壓器或廠用變壓器免受巨大的短路電流沖擊而損壞；2）防止波及站用直流系統(tǒng)，避免故障擴(kuò)大而造成經(jīng)濟(jì)損失。弧光保護(hù)裝置專(zhuān)業(yè)銷(xiāo)售。</p><div
