Emkhakheni wezinhlelo zikagesi, ukubaluleka kokukhetha umugqa wephutha osebenzayo akunakubukelwa phansi.Yilapho i-ukuhlelwa kwe-resistor efanayokungene ukudlala.Idivayisi yokukhetha imigqa ebanzi ifakwe ngokuhambisana nendawo yokungathathi hlangothi yesistimu futhi ixhunywe kukhoyili yokucindezela i-arc, engakhetha imigqa enephutha ngokunembe nangempumelelo.Ukuthi asetshenziswa ezinhlelweni zamakhoyili wokucindezela i-arc noma amakhabethe amelana nomhlabathi, izisetshenziswa ze-shunt resistor zidlala indima ebalulekile ekuqinisekiseni ukuvikeleka nokusebenza kahle kwezinhlelo zikagesi.
I-parallel resistor device iwukuqalwa kabusha kwesisekelo kubunjiniyela bakagesi.Ngokuhlanganiswa nephoyinti lokungathathi hlangothi kwesistimu kanye nekhoyili yokucindezela i-arc, ukunemba kokukhethwa komugqa wephutha kuyathuthukiswa.Lokhu kubaluleke kakhulu kumasistimu lapho ukunemba nokuthembeka kubaluleke kakhulu.Eqinisweni, ezinhlelweni zamakhoyili wokucindezela i-arc, idivaysi yokukhetha umugqa ehlanganisiwe yokumelana ne-parallel ingafinyelela ukunemba okumangazayo kokukhetha imigqa engu-100%, iqinisekise ukuthi amaphutha abonakala ngokushesha nangokunembile futhi axazululwa ngesikhathi.
Amayunithi we-shunt resistor, aziwa nangokuthi amakhabethe we-shunt resistor, aklanyelwe ukuhlinzeka ngokuvikeleka okuqinile kwezinhlelo zikagesi.Lolu cingo luqukethe izinto ezivikela umhlabathi nezinye izinto ezibalulekile futhi luklanyelwe ukumelana nobunzima bezinhlelo zikagesi zesimanje.Ikhono layo lokusebenza ngokuhambisana namaphoyinti angathathi hlangothi namakhoyili okucindezela i-arc kuyenza ibe yimpahla ebaluleke kakhulu ekuqinisekiseni ukuphepha nobuqotho bezinhlelo zikagesi.Ngokusebenzisa amadivaysi e-shunt resistor, opharetha nonjiniyela bangaqiniseka ukuthi amasistimu abo azomelana nokwehluleka okungase kube khona kanye nokucisha.
Enye yezinzuzo eziyinhloko zedivayisi yokumelana ne-parallel ikhono layo lokwenza lula ukukhetha komugqa wamaphutha.Ngokusebenzisa ubuchwepheshe obuthuthukisiwe nobunjiniyela obunembayo, le divayisi yenza amasistimu kagesi akwazi ukuhlonza ngokushesha nangokunembile futhi ahlukanise amaphutha.Lokhu akuthuthukisi nje kuphela ukwethembeka okuphelele kwesistimu kodwa futhi kunciphisa isikhathi sokuphumula kanye nomonakalo ongase ube khona ngenxa yokuhluleka kukagesi.Ngenxa yalokho, amabhizinisi nezimboni zingasebenza ngokuzethemba zazi ukuthi amakhono athuthukile wamadivayisi okumelana ne-shunt athuthukisa ingqalasizinda yawo kagesi.
Kafushane, amadivayisi we-shunt resistor angushintsho lomdlalo emkhakheni wokuvikela isistimu kagesi.Ukuhlanganiswa kwayo namakhoyili angathathi hlangothi kanye namakhoyili okucindezela i-arc kuthuthukisa ukunemba nokusebenza kahle komzila onephutha, kuyenze ibe yingxenye ebalulekile ekusetshenzisweni kukagesi kwesimanje.Ngokuklama kwazo okuqinile nekhono lokuthola ukunemba okungu-100% kokukhetha izintambo ezinhlelweni zekhoyili yokucindezela i-arc, amadivaysi e-shunt resistor afakazele ukuthi angamandla aqhuba ukuqamba okusha okuqhubekayo kwezobunjiniyela bakagesi.Njengoba amabhizinisi nezimboni ziqhubeka nokuthembela ezinhlelweni zamandla ukuze zisebenze, izisetshenziswa ze-shunt resistor zisebenza njengezibani zokuthembeka nokuvikela, ziqinisekisa ukuthi ingqalasizinda yamandla isebenza ngokusemandleni azo.
