Uhlolojikelele
Lolu chungechunge luyi-fuse yokuvikela i-capacitor, esetshenziselwa ukuvikela ngokweqile kwe-high-voltage shunt capacitor ohlelweni lwamandla, okungukuthi, ukusika i-fault capacitor ukuqinisekisa ukusebenza okuvamile kwe-capacitor engenaphutha.
Isimiso sokusebenza
I-fuse yakhiwe ngeshubhu yokucindezela i-arc yangaphandle, ishubhu yokucindezela i-arc yangaphakathi, i-fuse kanye nedivaysi yokukhipha ucingo lomsila.Ishubhu yangaphandle yokucindezela i-arc yenziwe nge-epoxy glass fibre cloth tube kanye ne-anti white steel paper tube, esetshenziselwa kakhulu ukufakwa, ukumelana nokuqhuma kanye nokuphulwa okusebenzayo kwe-capacitive current elinganiselwe;
Ishubhu yokucindezela i-arc yangaphakathi ingaqoqa ingcindezi eyanele yegesi engashi ngesikhathi sokuphuka ukuze kuthuthukiswe umthamo wokuphuka, ngakho-ke isetshenziselwa ukuphula i-capacitive current encane.Idivaysi yokukhipha ucingo lomsila ingahlukaniswa ngohlobo lwangaphandle lwentwasahlobo kanye nezakhiwo zohlobo lwe-anti swing ngokuya ngemibandela ehlukene yohlelo lokusebenza.Isakhiwo se-anti swing singahlukaniswa sibe izinhlobo ezimbili ngokuya ngezinhlobo ezihlukene zokubeka ama-capacitor afanisiwe: ukubekwa okuqondile nokubekwa okuvundlile.
Uhlobo lwentwasahlobo ye-tension yangaphandle i-tension spring isebenzisa i-stainless steel spring njengocingo lwe-fuse lwe-fuse.Uma i-fuse isebenza ngokujwayelekile, intwasahlobo isesimweni sokugcinwa kwamandla okushubile.Lapho intambo ye-fuse ihlanganiswa ngenxa yokweqisa kwamanje, isiphethu sikhipha amandla, ukuze intambo esele yomsila we-fuse idonswe ngokushesha ikhishwe kushubhu yokucindezela i-arc yangaphandle.Uma i-current ingu-zero, igesi ekhiqizwa amashubhu okucindezela i-arc yangaphakathi nangaphandle ingacisha i-arc, iqinisekise ukuthi i-fault capacitor ingahlukaniswa ngokuthembekile ohlelweni.
Lolu hlobo lwesakhiwo ngokuvamile lusetshenziswa ekuhlanganiseni uhlobo lwefreyimu ye-capacitor.Isakhiwo se-anti swing sishintsha intwasahlobo ye-tension yangaphandle ibe yi-internal tension spring structure ngeshubhu lokujikijela elivalekile, okungukuthi, isiphethu sishunyekwa eshubhuni elilwa nokushwibeka, futhi intambo ye-fuse ixhunywe netheminali ye-capacitor ngemva kokucindezela nokumiswa. nge-tension spring.
Lapho i-fuse ihlanganiswa ngenxa ye-overcurrent, amandla agciniwe we-tension spring ayakhululwa, futhi ucingo olusele ludonselwa ngokushesha eshubhuni eliphikisayo lokushwibeka.Ngesikhathi esifanayo, i-anti swing tube ihamba ngaphandle ngaphansi kwesenzo somthombo osizayo we-torsion endaweni ehleliwe, ebuye ikhuthaze ukwanda okusheshayo kokuphuka futhi iqinisekise ukunqanyulwa okuthembekile kwe-fuse.I-anti swing tube ivimbela intambo yomsila esele ukuthi ingashayisani nomnyango wesikrini se-capacitor nomnyango wekhabethe, iqeda izingozi zokuphepha ezingaba khona.
Izinyathelo zokuphepha zokusetshenziswa kwamafuse
1. Izici zokuvikela ze-fuse kufanele zihambisane nezici zokugcwala kakhulu zento evikelwe.Ngokucabangela i-current short-circuit yamanje, khetha i-fuse ehambisana namandla okuphuka;
2. I-voltage elinganiselwe ye-fuse kufanele ivumelane neleveli ye-voltage yomugqa, futhi amandla amanje alinganiselwe we-fuse kufanele abe mkhulu noma alingane namandla amanje okuncibilika;
3. Isilinganiso samanje samafuse kuwo wonke amaleveli emugqeni kufanele sifaniswe ngokufanele, futhi isilinganiso samanje sokuncibilika kwezinga langaphambilini kufanele sibe sikhulu kunomthamo wamanje olinganiselwe wokuncibilika kwezinga elilandelayo;
4. Ukuncibilika kwe-fuse kufanele kuhambisane nokuncibilika njengoba kudingeka.Akuvunyelwe ukwandisa ukuncibilika ngokuthanda kwakho noma ukufaka esikhundleni sokuncibilika nabanye abaqhubi.
