Ezimweni zanamuhla zezimboni, imisebenzi yokulayisha engaqondile kunsimbi, i-petrochemical, i-metallurgy, amalahle, ukuphrinta nokudaya nezinye izimboni kuvame ukukhiqiza inani elikhulu lama-harmonics.Lawa ma-harmonics ahambisana nesici samandla aphansi azodala ukunukubezeka okukhulu ohlelweni lukagesi futhi ekugcineni athinte ikhwalithi yokuphakelwa kukagesi.Ukubhekana nalezi zinselelo,izihlungi ze-passive ezine-voltage ephezuluabe yisixazululo esibalulekile, esihlinzeka ngesinxephezelo esibanzi namakhono okuhlunga ukuze kuthuthukiswe ikhwalithi yamandla nokuthembeka kwesistimu.
Idivayisi ephelele yesinxephezelo sesihlungi se-voltage ephakeme kakhulu iqukethe ama-capacitor okuhlunga, ama-reactors okuhlunga kanye nezinto eziphikisana ne-high-pass resistor, ezihlangene zakha ukushuna okukodwa noma isiteshi sokuhlunga se-high-pass.Lokhu kulungiselelwa kuvumela idivayisi ukuthi inciphise ngempumelelo ama-harmonics athile nama-harmonics ngaphezu kwe-oda elithile, ngaleyo ndlela inikeze imiphumela ebalulekile yokuhlunga.Ngaphezu kwalokho, isistimu iphinde yenze isinxephezelo samandla asebenzayo, ngaleyo ndlela ithuthukise isici samandla wesistimu futhi ithuthukise ukuqina kwamandla kagesi.Le ndlela ebanzi iqinisekisa ukuphepha nokwethembeka kohlelo lokuphakelwa kukagesi, okulwenza lube yimpahla esemqoka ezimbonini ezibhekana nezindaba zekhwalithi yamandla.
Enye yezinzuzo eziyinhloko zehigh voltage passive filtersumnotho nokutholakala kwabo.Ngesakhiwo esilula, ukusebenza okuthembekile nokugcinwa kalula, kuyisinqumo sokuqala sezinhlelo zokucindezela okuphezulu.Lokhu akugcizeleli ukusebenza kwazo kuphela kodwa futhi nokufaneleka kwazo kwezinhlelo zokusebenza ezihlukene zezimboni.Ngokuxazulula izinkinga ze-harmonic kanye nesici samandla, lezi zihlungi zidlala indima ebalulekile ekuthuthukiseni ikhwalithi yamandla nokuqinisekisa ukusebenza okungaphazamiseki kwezinqubo ezibalulekile zezimboni.
Ezimbonini zensimbi, i-petrochemical, i-metallurgy, amalahle, ukuphrinta nokudaya nezinye izimboni, ukuthunyelwaizihlungi ze-passive ezine-voltage ephezuluizuze izinzuzo ezibalulekile.Ngokuhlunga ngempumelelo ama-harmonics nokuthuthukisa isici samandla, lezi zihlungi zisiza ukunciphisa kakhulu ukungcoliswa kwesistimu yamandla.Lokhu-ke kuthuthukisa ikhwalithi yokuphakelwa kukagesi, okuvumela lezi zimboni ukuthi zisebenze kahle kakhulu futhi zithembeke.Umthelela omuhle wehigh voltage passive filterskulezi zimboni zigqamisa inani lazo njengotshalomali olunesu lamabhizinisi abheke ukuthuthukisa ingqalasizinda yawo yamandla.
Ukukhipha izihlungi ze-passive ze-voltage ephezulu kuyindlela esebenzayo yokuxazulula izinselele zekhwalithi yamandla ezindaweni zezimboni.Ngokuhlanganisa amandla okuhlunga athuthukile nesinxephezelo samandla asebenzayo, lawa madivaysi ahlinzeka ngesixazululo esibanzi sokunciphisa i-harmonic nokuthuthukiswa kwesici samandla.Ukusebenza kwabo kwezomnotho, kuhambisana nempumelelo efakazelwe ezinhlelweni ezihlukene zezimboni, kubenza babe yimpahla ebalulekile yamabhizinisi abheke ukuthuthukisa ikhwalithi yokuphakelwa kukagesi nokuqinisekisa ukusebenza okungenazihibe kwezinqubo ezibalulekile.Njengoba izimboni ziqhubeka nokubeka phambili ikhwalithi yamandla nokwethembeka kwesistimu,izihlungi ze-passive ezine-voltage ephezuluzigqame njengezixazululo ezinokwethenjelwa, ezisebenza kahle ukuhlangabezana nalezi zidingo eziguqukayo.
