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)的級差至少為300ms，甚至500ms ; </p> <p> ③ 過流保護(hù)的配合級差更是長達(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?？墒?，我們只要稍加注意，就會不難發(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。

的電壓。也就是說只要先接觸，之后又分開，很可能產(chǎn)生局部溫度很高的電弧而成為起火源。按電弧發(fā)生的不同部分可分為帶電導(dǎo)體間的電弧、帶電導(dǎo)體與地之間的電弧和絕緣表面的爬電。 </p> <p> 帶電導(dǎo)體間的電弧性短路起火：短路起火時(shí)有兩種可能，其一是兩導(dǎo)體（如相線與中性線）接觸時(shí)因短路電流產(chǎn)生的高溫，使接觸點(diǎn)金屬熔化，之后金屬熔化成團(tuán)收縮而脫離接觸的過程，在這種情況下可能建立電弧。“又如線路絕緣水平嚴(yán)重下降，雷電產(chǎn)生的瞬態(tài)過電壓或電網(wǎng)故障產(chǎn)生的暫態(tài)過電壓都可能擊穿劣化的線路絕緣而建立電弧?！薄半娀⌒远搪返钠鸹鹞ｋU(xiǎn)遠(yuǎn)大于上述金屬性短路的起火危險(xiǎn)?！?</p><p> 電弧光保護(hù)系統(tǒng)使用先進(jìn)的處理器技術(shù)來控制系統(tǒng)的功能。該處理器技術(shù)也使得電弧光保護(hù)系統(tǒng)功能的編程，可匹配開關(guān)柜的不同運(yùn)行方式。在跳閘回路里采用的半導(dǎo)體技術(shù)（可控硅開關(guān)）確保了開關(guān)柜里的供電開關(guān)以**小的延時(shí)得到跳閘信號。在不論是KEATON電弧光保護(hù)系統(tǒng)的主控單元，還是電弧光單元探測到電弧光，并且電流單元的整定的電流定值被超過，電弧光保護(hù)系統(tǒng)的跳閘信號將在極短時(shí)間內(nèi)到達(dá)供電開關(guān)。 </p> <p> 電流的信息也可直接取自安全電流回路，在此情況下，電弧光保護(hù)也可盡可能快的得到過流的信息。如果偶爾光線信號超過光線設(shè)定值或者電流信號超過電流設(shè)定值，系統(tǒng)不會輸出跳閘信號，也不會記憶在跳閘回路中，但是在主控單元上會顯示報(bào)警信號。在編程的時(shí)候，需要考慮系統(tǒng)按照用戶所希望的方式正常工作。采用光纖技術(shù)來向主控單元傳輸跳閘信號，確保了電弧光保護(hù)系統(tǒng)的完美功能，它的抗干擾能力強(qiáng)，跳閘信號可以非常迅速的輸出到斷路器。紫外光弧光保護(hù)，廠家直銷。</p><div
