Umsebenzi wenqwaba yokushaja ufana nalowo we-fuel dispenser esiteshini segesi. Ingalungiswa phansi noma odongeni, ifakwe ezakhiweni zomphakathi (izakhiwo zomphakathi, izitolo ezinkulu, izindawo zokupaka zomphakathi, njll.) nasezindaweni zokupaka zokuhlala noma iziteshi zokushaja, futhi ishaje izinhlobo ezahlukene zezimoto zikagesi ngokwamazinga ahlukene kagesi. Isiphetho sokufaka senqwaba yokushaja sixhunywe ngokuqondile negridi yamandla ye-AC. Amatheminali okukhiphayo ahlukaniswe abe yi-AC ne-DC, futhi afakwe amapulagi okushaja okushaja izimoto zikagesi.
Ukuphepha nokuthembeka kufanele kubhekwe ekwakhiweni kwenqwaba yokushaja. Ngakho-ke, izisetshenziswa zokuvikela eziphephile nezithembekile kufanele zisetshenziselwe ukuvikela i-overcurrent kanye ne-overvoltage ekugcineni kokufaka, ekugcineni kokuphumayo kanye nesixhumi esibonakalayo sokuxhumana. Lapha sincoma i-voltage ephezulu kanye ne-fuse yamanje ephezulu spfj160 evela ku-Littelfuse, umholi embonini ye-fuse. Le modeli iyisixazululo esifanelekile sokuvikela isifunda sokuphuma kwe-DC kwenqwaba yokushaja futhi isetshenziswe kabanzi emkhakheni wenqwaba yokushaja.
Uchungechunge lwe-Spfj luyi-fuse yokuqala esohlwini lwekhathalogi yesitifiketi se-ul2579 embonini kagesi, esetshenziselwa ukuvikela i-1000VDC, 70-450a high voltage kanye nemishini yamanje ephezulu. Ukuklanywa nokukhiqizwa kwayo kuhlangabezana nezidingo ze-IEC standard 60269-6, futhi isiphumelele isitifiketi sesicelo se-VDE 125-450a. Lawa mazinga aqinile angaqinisekisa ukuphepha kwezinto zokusebenza nabasebenzi, okwenza uchungechunge lwe-spfj lube umkhiqizo womhlaba ngempela. Imikhiqizo ye-125-450a inikeza usayizi wezindlu ze-J-Class, ezingasindisa isikhala esiningi kubakhiqizi bemishini futhi kunciphise kakhulu izindleko. Ngasikhathi sinye, i-Littelfuse ye-ejenti ye-Shiqiang ingaphinda inikeze isibambi se-fuse esingu-1000VDC kulolu chungechunge ukuze kuhlangatshezwane nezidingo ezihlukile zohlelo lwamanye amakhasimende.
I-voltage elinganiselwe ye-spfj160 ingu-1000VDC / 600vac futhi yamanje elinganiselwe ngu-160A, engahlangabezana nezidingo ze-DC zokushaja izinqwaba zamazinga ahlukahlukene. Isilinganiso sokuphuka kufika ku-200KA@600VAC mhlawumbe 20KA@1000VDC , i-breaking current elinganiselwe phezulu isho ukuthi i-fuse mancane amathuba okuthi iqhume ngaphansi kwezimo ezilinganiselwe, ngakho iphephe kakhudlwana futhi ithembekile.
