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，甘肅電弧光保護(hù)，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，甘肅電弧光保護(hù)，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，甘肅電弧光保護(hù)，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。

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(hào)。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(cè)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(hào)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(hào)超過光線設(shè)定值或者電流信號(hào)超過電流設(shè)定值，系統(tǒng)不會(huì)輸出跳閘信號(hào)，也不會(huì)記憶在跳閘回路中，但是在主控單元上會(huì)顯示報(bào)警信號(hào)。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(hào)，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(hào)可以非常迅速的輸出到斷路器。甘肅電弧光保護(hù)組屏弧光保護(hù)，歡迎來電咨詢。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="甘肅電弧光保護(hù),弧光保護(hù)" src="https://tyunfile.71360.com/UploadFile/keaton/637255090208730469/6645876.jpg"></div><p> 工作原理 </p> <p> 電弧光保護(hù)以電流單元為基礎(chǔ)分組，弧光探頭可以整定關(guān)聯(lián)到任意一組電流信號(hào)上。當(dāng)弧光單元把光信號(hào)從弧光傳感器傳輸?shù)交」獗Ｗo(hù)設(shè)備時(shí)，并且同時(shí)電流啟動(dòng)元件動(dòng)作和電弧光保護(hù)動(dòng)作，裝置可選擇弧光信號(hào)動(dòng)作單判據(jù)作為動(dòng)作邏輯判斷。 </p> <p> 當(dāng)檢測(cè)到本身硬件故障時(shí)，發(fā)出告警信號(hào)，同時(shí)閉鎖整套保護(hù)。硬件故障包括：采樣回路故障、RAM出錯(cuò)、定值出錯(cuò)等。 </p> <p> <br /> </p> <p> 端子圖及定義 </p> <p> 主要的端子數(shù)量有：6個(gè)弧光信號(hào)檢測(cè)接口，用于接收來自弧光傳感器的弧光故障信號(hào)。4個(gè)數(shù)據(jù)通訊接口，2路RS485，1路CAN總線，1路以太網(wǎng)。4路快速跳閘輸出接口，符合IEC255-23繼電器標(biāo)準(zhǔn)。2路報(bào)警出口，其中一路為裝置故障出口。12路電流輸入，檢測(cè)4組三相電流信號(hào)，用于判斷故障電流。 </p> <p> </p><p> <p> 電力系統(tǒng)由于各種的短路原因可引起弧光，弧光會(huì)以300m/s的速度爆發(fā)，摧毀途中的任何物質(zhì)。只要系統(tǒng)中不斷電，弧光就會(huì)一直存在。 </p> <p> 弧光保護(hù)裝置是**近幾年隨著光電技術(shù)的發(fā)展而發(fā)展起來的一種新型保護(hù)，是以電流和弧光為主要判據(jù)，與傳統(tǒng)保護(hù)相比增加了弧光（光強(qiáng)）這一判據(jù)。適用于35KV變電站、中低壓開關(guān)柜中，主要解決由于弧光短路引發(fā)的中低壓母線故障。 </p> <p> 開關(guān)柜中采用電弧光保護(hù)裝置可降低電弧光短路故障對(duì)于設(shè)備的損害，避免變壓器因近距離母線故障造成損壞，延長(zhǎng)變壓器的使用壽命，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，減少因電弧光故障造成設(shè)備停運(yùn)的時(shí)間，更快地恢復(fù)供電。 </p> </p> <p> <br />
