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。 </p><p> 電弧光保護(hù)裝置的主要作用 </p> <p> 1、減專少或降低電弧光對(duì)于人體的傷害。 </p> <p> 2、減少或降低電弧光短路故障對(duì)于設(shè)備的損害。 </p> <p> 3、避免變壓器因近距離母線故障造成動(dòng)穩(wěn)定破壞，延長(zhǎng)變壓器的使用壽命。 </p> <p> 4、縮短電弧光故障切除時(shí)間，避免波及站內(nèi)直流系統(tǒng)造成重大損失。 </p> <p> 5、減少因電弧光故障造成設(shè)備停運(yùn)的時(shí)屬間，更快地恢復(fù)供電。 </p> <p> 主要應(yīng)用于以下場(chǎng)合 </p> <p> 1、電力變電站。 </p> <p> 2、火電廠電氣段開(kāi)關(guān)柜母線室及饋線柜。 </p> <p> 3、風(fēng)電場(chǎng)升壓站集電線路開(kāi)關(guān)柜。 </p> <p>
