Ungayehlisa kanjani impilo yebhethri yesilinganiso sokuhluleka kwamandla e-UPS

ଲେଖକ: ଆଇଫ୍ଲୋପାୱାର - Portable Power Station supplementum

Ngezibalo zamaphutha ahlukahlukene emsebenzini wokulungisa we-UPS, lesi siphetho singafinyelelwa: amandla kagesi e-UPS aqoqwe ngemuva, iphutha elibangelwa ibhethri lidlula ama-50% wephutha eliphelele. Ukunikezwa kwamandla okuku-inthanethi kwe-UPS, ngoba ukwakheka kwayo kwesekethe kunengqondo, ibhalansi ethathwe umthamo wengxenye yamandla okushayela. Ngezibalo zamaphutha ahlukahlukene emsebenzini wokulungisa we-UPS, lesi siphetho singafinyelelwa: amandla kagesi e-UPS aqoqwe ngemuva, iphutha elibangelwa ibhethri lidlula ama-50% wephutha eliphelele.

Ukunikezwa kwamandla okuku-inthanethi kwe-UPS, ngenxa yokuthi idizayini yayo yesekethe inengqondo, ibhalansi ethathwe umthamo wengxenye yamandla edrayivu, ngakho-ke izinga lokuhluleka kwesekethe yamandla liphansi kakhulu, uma liqhathaniswa nezinga lokuhluleka okubangelwa iphakethe lebhethri libe ngaphezu kuka-60% noma ngaphezulu. Kungabonakala ukuthi ukusebenzisa kahle nokunakekela ibhethri kungenye yezinto ezibalulekile ezinweba impilo yebhethri futhi zinciphise inani lokuhluleka kwesilinganiso sokuphakelwa kwamandla kwe-UPS. Ukuhlola okuvamile ngezikhathi ezithile hlola i-voltage yokugcina nokumelana kwangaphakathi kwebhethri leyunithi ngayinye.

Ngeyunithi yebhethri engu-12V, uma umehluko wevolthi yesiphetho phakathi kweyunithi yebhethri ngayinye utholakala ekuhlolweni, ibhethri yeselula kufanele ilinganiswe ukuze kubuyiselwe ukumelana kwangaphakathi kwebhethri ukuze kubuyiselwe ukumelana kwangaphakathi kwebhethri okungaphezu kuka-0.4 V noma ngaphezulu kuka-80mΩ noma ngaphezu kuka-80mΩ. Futhi susa i-voltage yokuphela phakathi kweyunithi ngayinye yeyunithi.

I-voltage yokushaja ithatha i-13.5 ~ 13.8V uma ishaja.

Iningi lamabhethri axazululwe ngokushajwa okuhle kwebhalansi angabuyisela ukumelana kwawo kwangaphakathi kokuthi 30MΩ noma ngaphansi. Ngesikhathi sokusebenza, ukunikezwa kwamandla kwe-UPS kukhishwa ukungalingani okuchazwe ngenhla kwesici seyunithi ngayinye yeyunithi ngokuhamba kwesikhathi, akunakwenzeka ukuthembela futhi ku-loop yokushaja ngaphakathi kwamandla kagesi we-UPS, ngakho-ke ibhethri eliye lahlukaniswa ngokungabekezeleleki lenzekile. Iphakheji, uma ungakukhiphi ungaxhunyiwe ku-inthanethi, lizoba bucayi kakhulu.

Ukuntanta kabusha isikhathi sokuphumula samandla e-UPS izinsuku ezingaphezu kweziyi-10, ngaphambi kokuqalisa kabusha, ukunikezwa kwamandla kwe-UPS kufanele kuqalwe ngaphansi kwezimo ezingalayishiwe ukuze kuphinde kusetshenziswe ishaja yokushajwa kokushaja emshinini ukuze intante 10 kuya ku-12h noma ngaphezulu. Ukunikezwa kwamandla kwe-UPS kusesimweni sokuntanta ngaphandle kwenqubo yokukhipha, okulingana nesimo "sokugcina".

Uma lesi simo siqhubeka, sihlulekile ukulahlwa ngenxa "yendawo yokugcina amanzi" ngenxa "yokugcina isikhathi eside", okufiswa ukwandisa ukumelana kwangaphakathi, futhi ukumelana kwangaphakathi kungafinyelela ku-Ω embalwa. Sithole ukuthi ngemva kwezinyanga ezingu-2 zegumbi lokushisa, ibhethri ingasetshenziswa cishe ngo-97% yenani layo elilinganiselwe. Uma igcinwe izinyanga eziyisi-6, umthamo wayo wokusebenzisa uba ngu-80% womthamo olinganiselwe.

Uma izinga lokushisa lokulondoloza linyuswa, amandla okusebenzisa azokwehla. Ngakho-ke, kuphakanyiswa ukuthi umsebenzisi kungcono kakhulu ukukhulula okokufaka kwamapayipi njalo ngo-20 ° C, ukuze ukunikezwa kwamandla kwe-UPS kusetshenziswe amandla okunikezwa kwebhethri ku-inverter. Kodwa-ke, lo msebenzi akufanele ube mude kakhulu, futhi cishe u-30% womthwalo ungaba ngu-30% womkhiqizo olinganiselwe, ungakhishwa.

Yehlisa impilo yesevisi yokukhishwa okujulile, okuhlobene eduze nayo kuyakhishwa. Ukukhanya komthwalo wamandla kagesi we-UPS, inani lomthamo wesitoreji sikagesi likhulu kanye nomthamo waso olinganiselwe, isilinganiso sesilinganiso sesitoreji samandla sinjalo, lapho ibhethri livaleka ngokuzenzakalelayo lapho i-voltage yebhethri iphansi kakhulu ngenxa ye-voltage yebhethri ephansi Ukujula kokukhipha kujulile uma kuqhathaniswa. Ingabe inqubo yangempela inciphisa kanjani ibhethri ibhethri elicindezelekile? Indlela ilula kakhulu: Uma amandla kagesi e-UPS eyisisekelo sokuphakelwa kwamandla, ashintshwa esuka kubhethri aye ku-inverter.

Iningi lamandla kagesi e-UPS lizokhalisa umsindo we-alamu yomjikelezo ku-gap 4s, futhi yazise ukuthi umsebenzisi unikezwa ibhethri. Lapho ezwa umsindo we-alamu uyaphuthuma, izobonisa ukuthi ukunikezwa kwamandla sekuvele kujulile, futhi kufanele kuxazulule ngokushesha ukunikezwa kwamandla kwe-UPS ngokushesha. Akuphoqiwe, ngokuvamile ungavumeli amandla e-UPS abelokhu esebenza kuze kube yilapho i-voltage yebhethri iphansi kakhulu futhi ukuvala shaqa okuzenzakalelayo kuyaphela.

Ukusebenzisa ukunikezwa kwamandla kwe-UPS kokuphakela kwamandla e-UPS isikhathi eside emakethe, ukunikezwa kwamandla kagesi aphansi noma okushintsha njalo, kufanele konakaliswe ngaphambi kwesikhathi ukushajwa kwesikhathi eside, futhi kufanele kusetshenziswe ngokugcwele ukushaja ibhethri ukuze kuqinisekiswe ibhethri. Ngesikhathi esanele sokushaja ngemva kokukhishwa ngakunye. Uma ibhethri lidangele, lingaphezu kwama-90% omthamo olinganiselwe okungenani amahora ayi-10 kuye kwayi-12.

Gcina ibhethri elivaliwe elingenaso iso lamandla akhethiwe e-UPS eshaja ayikwazi ukushajwa "ishaja esheshayo" yohlobo lwesilicon elawulwayo. Lokhu kungenxa yokuthi le shaja izobangela ibhethri ukuthi ibe sesimweni sokushaja esinzima "sokushaja okuchichima ngokushesha" kanye "nokushaja okudlula ngokushesha. Lesi simo sizokwenza ibhethri lehle kakhulu, futhi ibhethri izolahlwa uma isinzima.

Uma usebenzisa ugesi we-UPS wesekethe yokushaja enqamukile ye-voltage engaguquki, hhayi ukulungisa i-voltage yebhethri indawo yokusebenza yokuvikela ephansi kakhulu, ngaphandle kwalokho, ijwayele ukushaja ngokweqile esigabeni sokuqala sokushaja. Yiqiniso, kungcono ukusebenzisa ishaja enakho kokubili okwamanje, kanye nokucindezela okuqhubekayo. Qinisekisa ukuthi umthamo webhethri yezinga lokushisa lokunikezwa kwamandla uhlobene eduze nezinga lokushisa elizungezile.

Ngokuvamile, imingcele yokusebenza yebhethri ilinganiswa ekamelweni lokushisa lika-20 ° C, futhi lapho izinga lokushisa lingaphansi kuka-20 ° C, umthamo wokugcina amandla uzoncishiswa, kuyilapho izinga lokushisa lingaphezu kuka-20 ° C, liyatholakala Umthamo osetshenzisiwe uzokhula kancane. Amamodeli ahlukene amamodeli ahlukene amamodeli ahlukene ahluke ngezinga lokushisa. Ngokwezibalo, uma ku--20 ° C, ibhethri lingafinyelela kuphela cishe ku-60% wamandla okuzisholo.

Umthelela wezinga lokushisa elibonakalayo awunakuzitshwa. Yiqiniso, kuyadingeka ukunweba impilo yesevisi yephakethe lebhethri hhayi nje ukunaka ukulungiswa, kodwa futhi ucabange izici zomthwalo (ukumelana, inductance, amandla) kanye nosayizi lapho ukhetha. Ungalenzi ibhethri lisebenze ngokugcwala ngokweqile isikhathi eside, ukuze ungagwemi ukuphuma kwebhethri.
