合閘同期性亦正常。3.開關(guān)動(dòng)靜觸頭在接通電路時(shí)沒有產(chǎn)生強(qiáng)烈電弧。因此，開關(guān)出現(xiàn)飛弧短路和熱擊穿短路的可能性較小。4.在動(dòng)靜觸頭前端接觸面邊沿有微小的電火花灼蝕點(diǎn)，這說明在動(dòng)靜觸頭接觸瞬間亦有微小電弧產(chǎn)生。但考慮到滿足本使用類別的接通和分?jǐn)鄺l件當(dāng)時(shí)可能已經(jīng)破壞，出現(xiàn)微小的電弧亦屬正常。二、質(zhì)量問題（一）瞬間電壓在“”弧光短路的一瞬間，SIWOH1-630開關(guān)相間絕緣承受的電壓究竟有多高呢？根據(jù)當(dāng)時(shí)開關(guān)電源側(cè)配置的電壓保護(hù)水平為，可以判定：當(dāng)時(shí)開關(guān)在ms級時(shí)限內(nèi)承受的電壓在。同時(shí)根據(jù)此電容器極間耐壓1130V（10S）和極對殼耐壓3000V（1min）的性能，可判定1200V為此電容器在ms級時(shí)限內(nèi)極間耐壓的上限。SIWOH1-630開關(guān)的額定沖擊耐受電壓雖然可達(dá)6-10kV，但它的額定絕緣電壓只有750V（在塑料外殼發(fā)熱溫度低于80℃的條件下）。因此，若當(dāng)時(shí)電路中有（～）Uj瞬間過電壓出現(xiàn)，也會(huì)對開關(guān)構(gòu)成威脅。這里所說的質(zhì)量問題，主要是看開關(guān)的額定沖擊耐受電壓、額定絕緣電壓、空氣中小電氣間隙、小爬電距離和絕緣表面溫升限值等技術(shù)指標(biāo)是否合格。（二）閃絡(luò)短路憑經(jīng)驗(yàn)。</p><p>

小爬電距離＝40mm。放電的危險(xiǎn)是存在的?！?。經(jīng)驗(yàn)證明：當(dāng)開關(guān)在較大電流沖擊下瞬間溫升是該數(shù)值的兩倍以上時(shí)，開關(guān)塑料外殼表面電阻會(huì)急劇下降，此時(shí)加上＞750V的高電壓，附著著灰塵的相間絕緣材料表面發(fā)生放電閃絡(luò)短路是完全可能的。4.根據(jù)以上非常有限技術(shù)條件下的分析，筆者認(rèn)為：開關(guān)的接觸機(jī)構(gòu)和絕緣指標(biāo)基本上沒有嚴(yán)重的問題。開關(guān)短路是由于當(dāng)時(shí)電路里出現(xiàn)了超出開關(guān)技術(shù)指標(biāo)的異常狀態(tài)。三、安裝問題本開關(guān)安裝存在明顯問題。（一）使用說明書要求本開關(guān)安裝單位是國內(nèi)某儀表廠。某日，該廠在為大廈更換新開關(guān)時(shí)隨機(jī)帶來一份《SIWOH1-63～1250系列隔離開關(guān)熔斷器組使用說明書》。說明書內(nèi)容共分八部分。其中第七部分-使用與維修-第2條要求：“開關(guān)上的接線端子和接線裸母線應(yīng)包扎絕緣物，防止開關(guān)相間短路?！保ǘ┐髲B現(xiàn)場安裝實(shí)況大廈南北變配電室18臺低壓無功補(bǔ)償柜上的18臺SIWOH1-630隔離開關(guān)熔斷器組，都沒有按照該使用說明書第七部分-使用與維修-第2條要求安裝。圖10開關(guān)上的接線端子是裸露導(dǎo)體未包扎絕緣物（三）可以說，這一條是開關(guān)制造廠家根據(jù)SIWOH1系列產(chǎn)品的技術(shù)特點(diǎn)，提出的針對性安全要求。如果按照這一條做了。各種弧光保護(hù)廠家直銷。重慶弧光保護(hù)怎么操作</p><p
