Uhlolojikelele

I-Drop out fuse iyidivayisi engaphandle yokuvikela amandla kagesi aphezulu.Kuyindlela evame ukusetshenziswa kakhulu yokuvikela isifunda esifushane emigqeni yegatsha yemigqa yokusabalalisa kanye nama-transformer okusabalalisa.Ngokuyinhloko isetshenziselwa ukuvikela ama-transformers noma imigqa emthelela obangelwa isifunda esifushane, ukulayisha ngokweqile nokushintsha kwamandla.Inezici zomnotho, ukusebenza okulula nokuvumelana nezimo okuqinile endaweni yangaphandle.Ngaphansi kwesimo sephutha lamanje, i-fuse izoshaya futhi yakhe i-arc.Ishubhu yokucisha i-arc iyashisisa futhi iyaqhuma, ibangele amandla kagesi aphezulu.I-fuse manje isisendaweni evulekile futhi u-opharetha udinga ukuvala i-current.Vala ngokufaka i-tape eshisayo.Othintwayo oyinhloko nomsizi kuxhunyiwe.Ifakwe entanjeni yegatsha yolayini wokusabalalisa ongu-10kV, onganciphisa ububanzi bokunqamuka kukagesi.Ngenxa yokuthi inephuzu elisobala lokunqamula, inomsebenzi wokunqamula iswishi, ukudala indawo yokusebenza ephephile yemigqa nemishini esigabeni sokulungisa, nokwandisa umuzwa wokuphepha wabasebenzi abalungisayo.

Ukuxazulula inkinga

(1) I-fuse ohlangothini oluyinhloko lwe-transformer isetshenziswa njengesivikelo esiyisipele se-transformer ngokwayo kanye nephutha lesibili lomugqa ophumayo.Ihambisana nesikhathi sesenzo sokuvikela umugqa ophumayo wokushintsha umugqa ophumayo, futhi kufanele sibe ngaphansi kwesikhathi sokuphuka sesiphazamisi sesekhethi yesiteshi esingaphansi.Kudingeka ukuthi i-fuse ihlanganiswe futhi i-breaker circuit outlet ingasebenzi.Uma umthamo we-transformer ungaphansi kuka-100kV.A, i-fuse ohlangothini oluyinhloko ingakhethwa njengezikhathi ezingu-2-3 zamanje ezilinganiselwe;Ku-transformer yokusabalalisa engu-100kV.A nangaphezulu, i-fuse ohlangothini oluyinhloko ingakhethwa njengezikhathi ezingu-1.5~2 zamanje ezilinganiselwe.

(2) I-fuse eyinhloko yomugqa wegatsha isetshenziselwa ikakhulukazi ukuvikela ukulayisha ngokweqile.Ngokuvamile, i-current elinganisiwe ye-fuse ikhethwa ngokuya ngomthwalo omkhulu wamanje womugqa wegatsha.Isikhathi sokuhlanganisa kufanele sibe ngaphansi kwesikhathi sokusetha sesiteshi esiphumayo sokushintsha idivayisi yamanje yokuvikela.

(3) I-akhawunti yokusebenza nokugcinwa kanye nohlelo lwamafuse okuyeka kuyosungulwa.Ama-fuse ayeke asebenze iminyaka engaphezu kwemi-5 azoshintshwa abe ngamaqoqo.

(4) Ukuthuthukisa ikhwalithi yobuchwepheshe kanye nenqubo yokulungisa yabasebenza ngogesi.Lapho ufaka noma ushintsha i-fuse, amandla azofaneleka ukugwema ukuxega kakhulu noma ukucinana kakhulu.

(5) Ngokulimala kokulingwa okungalingani kuzo zombili iziphetho zeshubhu ye-fuse, umkhiqizi uzophatha "i-chamfering" noma enze okunye ukuthuthukiswa.

Ukufakwa kwamafuse aphumayo

(1) Ngesikhathi sokufakwa, ukuncibilika kufanele kuqiniswe (ukuze ukuncibilika kukwazi ukumelana namandla aqinile angaba ngu-24.5N), ngaphandle kwalokho othintana naye angase ashise kakhulu.I-fuse efakwe engalweni yesiphambano (uhlaka) izoqina futhi ithembeke ngaphandle kokuzamazama noma ukunyakaziswa.

(2) Ishubhu elincibilikayo lizoba ne-engeli yokuthambekela eya phansi engu-25 °± 2 °, ukuze ishubhu elincibilikayo liwe ngokushesha ngesisindo salo lapho likhipha inyibiliko.

(3) I-fuse izofakwa engalweni yesiphambano (uhlaka).Ngenxa yezizathu zokuphepha, ibanga eliqondile ukusuka phansi akufanele libe ngaphansi kwama-4m.Uma ifakwe ngaphezu kwe-transformer yokusabalalisa, ibanga elivundlile elingaphezu kuka-0.5m lizogcinwa kusukela emngceleni wekhonta wangaphandle we-transformer yokusabalalisa.Ukuwa kwepayipi elincibilikayo kudale ezinye izingozi.

(4) Ubude be-fuse kufanele bulungiswe ngendlela efanele.Ukucatshangelwa kokuphepha kudinga ukuthi i-duckbill ingagcina ngaphezu kwezingxenye ezimbili kwezintathu zobude bokuthintwayo ngemva kokuba ivaliwe ukuze igweme ukungaziphathi kahle ngesikhathi sokusebenza.Ishubhu le-fuse akufanele lithinte i-duckbill ukuvimbela ishubhu elincibilikayo ukuba liwe ngesikhathi ngemva kokuba ukuncibilika kuqhunyiswe.

(5) Ukuncibilika okusetshenzisiwe kufanele kube umkhiqizo ojwayelekile womkhiqizi ojwayelekile futhi ube namandla athile emishini.Ukucatshangelwa kokuphepha kuvame ukudinga ukuthi ukuncibilika kungamelana namandla aqinile angaphezu kuka-147N.

(6) I-10kV drop out fuse ifakwa ngaphandle ukuze iphephe futhi ibanga liyadingeka ukuthi libe likhulu kuno-70cm.

Qaphela: Ngokuvamile, akuvunyelwe ukusebenzisa i-fuse yokukhipha ekulayisheni, kodwa kuvunyelwe kuphela ukusebenzisa imishini engalayishi (umugqa).Nokho, ngaphansi kwezimo ezithile, kuvunyelwe ukulayisha njengoba kudingeka
