Uhlobo lwe-cuout fuse:
I-fuse yohlobo lwe-drop-type iyiswishi evame ukusetshenziswa kakhulu yokuvikela isifunda esifushane emigqeni yegatsha yemigqa yokusabalalisa engu-10kV kanye nama-transformer okusabalalisa.Inezici zomnotho, ukusebenza okulula, ukuguquguquka okunamandla endaweni yangaphandle nokunye.Isetshenziswa kakhulu ohlangothini oluyinhloko lwemigqa yokusabalalisa engu-10kV kanye nama-transformer okusabalalisa ukuze kuvikelwe futhi kushintshwe imishini nokusebenza kokusika.
Ifakwe kulayini wegatsha womugqa wokusabalalisa ongu-10kV, onganciphisa ububanzi bokuhluleka kwamandla.Ngenxa yephoyinti layo elisobala lokunqamula le-fuse yohlobo lwe-drop-voltage ephezulu, inomsebenzi wokuhlukanisa iswishi, edala indawo yokusebenza ephephile yolayini wokulungisa nezinto zokusebenza, futhi ikhulise umuzwa wokuphepha wabasebenzi abalungisayo.Kufakwe ku- i-transformer yokusabalalisa, ingasetshenziswa njengesivikelo esiyinhloko se-transformer yokusabalalisa, ngakho-ke iye yadumala kulayini wokusabalalisa we-10kV kanye ne-transformer yokusabalalisa.
Ukufakwa kwe-drop-type fuse:
(1) ngesikhathi sokufakwa, ukuncibilika kufanele kuqiniswe (ukuze ukuncibilika kube yi-tension ye-24.5N), ngaphandle kwalokho kulula ukubangela ukushisa kwezinwele.
(2) i-fuse izofakwa ngokuqinile nangokuthembekile ku-crossarm (uhlaka) ngaphandle kokuzamazama noma ukunyakaziswa.
(3) ipayipi elincibilikisiwe kufanele libe ne-Engeli eya phansi engu-25°±2°, ukuze ipayipi elincibilikisiwe liwe ngokushesha ngesisindo salo lapho incibilika ihlanganiswa.
(4) i-fuse izofakwa engalweni ephambene (uhlaka) ngebanga eliqondile elingekho ngaphansi kwama-4m ukusuka phansi.Uma ifakwe ngaphezu kwe-transformer yokusabalalisa, ibanga elivundlile phakathi kwe-fuse kanye nomngcele we-contour wangaphandle we-transformer uzogcinwa ebangeni elingaphezu kuka-0.5m, uma kwenzeka ezinye izingozi ezibangelwa ukwehla kwe-fuse.
(5) ubude be-fuse buzolungiswa bube sezingeni elimaphakathi.Kudingeka ukuthi ulimi loqhwaku lwedada lukwazi ukubamba ngaphezu kwezingxenye ezimbili kwezintathu zobude bokuthintwa ngemva kokuvala, ukuze kugwenywe isenzo esingalungile sokuziwisa ngokusebenza.
(6) ukuncibilika okusetshenzisiwe kufanele kube yimikhiqizo ejwayelekile yabakhiqizi abajwayelekile, futhi kube namandla athile emishini, izidingo ezijwayelekile zokuncibilika zingamelana okungenani no-147N ngaphezu kokushuba.
(7) ifyuzi yohlobo lokudonsa eyi-10kV izofakwa ngaphandle futhi ibanga le-interphase lizoba likhulu kuno-70cm.
Ukusebenza kwe-drop-type fuse:
Ngaphansi kwezimo ezijwayelekile, akuvunyelwe ukusebenzisa i-drop fuse enomthwalo, ukuyivumela kuphela ukuthi isebenzise imishini engalayishi (umugqa). Nokho, ama-transformer okusabalalisa anomthamo olinganiselwe ongaphansi kuka-200kVA kanye nemigqa yegatsha yezintambo zokusabalalisa ezingu-10kV kumanethiwekhi ezolimo. bavunyelwe ukusebenza ngaphansi komthwalo ngokwezidingo ezilandelayo:
(1) ukuhlinzwa kuzokwenziwa abantu ababili (umuntu oyedwa ozogada nomuntu oyedwa ozosebenza), inqobo nje uma bezogqoka amagilavu avikelayo afanelekile, amabhuzu avikelayo kanye nezibuko, futhi basebenze ngezinti ezifanelekayo ezifaka amazinga kagesi ahambisanayo.Ukusebenza akuvunyelwe esimweni sezulu sombani noma imvula enkulu.
(2) lapho udonsa umsebenzi wamabhuleki, ngokuvamile kushiwo ukudonsa isigaba esimaphakathi kuqala, bese kuba yisigaba se-leeward, bese ekugcineni kube nesohlangothini olubheke ngasemoyeni. Lokhu kungenxa yokuthi isiguquli sokusabalalisa sisuka ekusebenzeni kwesigaba sesithathu ukuya kokusebenza kwesigaba sesibili, donsa isigaba esiphakathi esikhiqizwe ubuncane be-arc spark, ngeke kubangele ukujikeleza okufushane phakathi. ngisho noma kukhona i-overvoltage, okuholela ekujikelezeni okufushane phakathi kokungenzeka kube kuncane kakhulu.Ekugcineni, lapho isigaba se-upwind sidonswa, i-capacitive current kuphela emhlabathini, inhlansi ebangelwayo ibe yincane kakhulu.
(3) lapho iswishi ivaliwe, ukulandelana kokusebenza kuyahlehliswa lapho iswishi idonswa.Okokuqala, isigaba se-upwind side sivaliwe, bese isigaba se-leeward side sivaliwe, futhi ekugcineni isigaba esimaphakathi siyavalwa.
(4) ukusebenza kweshubhu elincibilikisiwe kuwumsebenzi ovamile.Uma ungayinaki, izobangela ukuthi othintana naye ashise futhi kuholele ekuthinteni okubi.Othintana naye uzoshiswa ngokweqile futhi intwasahlobo izokhishwa.Ngakho-ke, donsa, vala ithubhu elincibilikayo ukuze uphoqelele ukulinganisa, ukuvala okuhle, ukuhlola ngokucophelela ulimi lungakwazi ukubopha ulimi ngokuqinile izingxenye ezimbili kwezintathu zobude obungenhla, ungadonsa. ihhuku yebhuleki emlonyeni wedada ukuze ucindezele phansi izikhathi ezimbalwa, bese uzama ukudonsa ngobumnene, uhlole ukuthi ingabe ilungile yini. anele, kulula ukubangela ukushiswa kokuxhumana noma ukuwa kweshubhu elincibilikayo
