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 amandla engxenye yamandla edrayivu, ngakho-ke isekethe yokuphakela amandla iphansi kakhulu, uma kuqhathaniswa 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.

1. Ukuhlola okuvamile ngezikhathi ezithile hlola i-voltage yokugcina nokumelana kwangaphakathi kwebhethri leyunithi ngayinye. Ngeyunithi yebhethri engu-12V, uma i-voltage yokugcina phakathi kweyunithi yebhethri ngayinye itholakala ekuhlolweni, ibhethri yeselula kufanele ilinganiswe ukuze kubuyiselwe ukumelana kwangaphakathi kwebhethri ngaphezu kuka-0.

4 V noma ngaphezulu kuka-80mΩ noma ngaphezulu. Futhi susa i-voltage yokuphela phakathi kweyunithi ngayinye yeyunithi. I-voltage yokushaja ithatha i-13.

5 ~ 13.8V uma ishaja. Amabhethri amaningi anenqubo yokushaja yebhalansi enhle angabuyisela ukumelana kwawo kwangaphakathi ku-30MΩ.

Ngesikhathi sokusebenza, ukunikezwa kwamandla kwe-UPS kuyaqedwa ngenxa yokungalingani okuchazwe ngenhla kwezici zebhethri zeyunithi ngayinye, okungenakwenzeka ukuthembela kumjikelezo wokushaja ngaphakathi kwamandla kagesi we-UPS, ukuze lesi sici sibe nebhethri elingabekezeleleki kakhulu. Qembu, uma okungaxhunyiwe ku-inthanethi kungakhokhiswa ngesikhathi, ukungalingani kwakho kuzoba kubi kakhulu. 2.

Ukuntanta kabusha isitobhi samandla se-UPS izinsuku ezingaphezu kweziyi-10. Ngaphambi kokuqalisa kabusha, ukunikezwa kwamandla kwe-UPS kufanele kuqalwe ngaphansi kwezimo ezingalayishiwe ukuze kuphinde kusetshenziswe iluphu yokushaja emshinini ukuntanta ibhethri 10 kuya ku-12h noma ngaphezulu. Ukunikezwa kwamandla kwe-UPS kusesimweni sokuntanta ngaphandle kwenqubo yokukhipha, okulingana nesimo "sesitoreji.

". Uma lesi simo siside kakhulu, ibhethri alikaqedwa ngenxa "yokugcina isikhathi eside", okubonakaliswa ngokuyinhloko njengokwanda kokumelana nebhethri kwangaphakathi, futhi ukumelana kwangaphakathi kungafinyelela ku-Ω embalwa. Sithole ukuthi ngemva kwezinyanga ezingu-2 zegumbi lokushisa, ibhethri ingasetshenziswa cishe ku-97% yenani layo elilinganiselwe.

Uma isitoreji siyizinyanga eziyisi-6, umthamo waso wokusebenzisa uba ngu-80% womthamo olinganiselwe. Uma izinga lokushisa lesitoreji likhuphuka, amandla ayo okusebenzisa azokwehla. Ngakho-ke kunconywa ukuthi umsebenzisi kungcono kakhulu ukuthi akhiphe okokufaka kwamapayipi njalo ngo-20 ° C, ukuze ukunikezwa kwamandla kwe-UPS kusetshenziswe ibhethri ukunikeza amandla ku-inverter.

Kodwa-ke, lo msebenzi akufanele ube mude kakhulu, futhi cishe u-30% womthwalo ungaba ngu-30% womkhiqizo olinganiselwe, ungakhishwa. 3. Ukunciphisa impilo yesevisi yokukhishwa okujulile kagesi kuhlobene eduze nokujula kwawo okukhishwayo.

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 ukunikezwa kwamandla kwe-UPS kukuphazanyiswa okuvamile, kushintshiwe kusukela kubhethri kuya ku-inverter, amandla amaningi e-UPS azokhala umsindo we-alamu yomjikelezo ku-gap 4S, ukwazisa umsebenzisi ukuthi manje ngebhethri. Lapho ezwa umsindo we-alamu uyaphuthuma, ukunikezwa kwamandla sekuvele kujulile, futhi kufanele ngokushesha enze ukwelashwa okuphuthumayo, ukuvala ukunikezwa kwamandla kwe-UPS.

Akuphoqiwe, ngokuvamile ungavumeli amandla e-UPS abelokhu esebenza kuze kube yilapho i-voltage yebhethri iphansi kakhulu futhi ukuvala shaqa okuzenzakalelayo kuyaphela. 4. Ukusebenzisa ukushajwa okuphezulu okuphezulu kokuphakelwa kwamandla kagesi ku-UPS isikhathi eside emakethe, ukunikezwa kwamandla kagesi aphansi noma amandla amiswa njalo, ukuvimbela ibhethri ukuthi lonakaliswe ukushajwa kwesikhathi eside, kufanele isetshenziswe ngokugcwele ukushaja ibhethri ebhethrini.

Qinisekisa ukuthi ibhethri linesikhathi esanele sokushaja ngemva kokuphuma ngakunye. Ngokuvamile, ngemva kokuba ibhethri selikhishiwe, lishajwa ku-90% womthamo olinganiselwe okungenani amahora angu-10 kuya kwangu-12. 5, naka ukukhethwa kweshaja yokusebenzisa ibhethri ye-UPS engenamandla yokuvala amandla engakwazi ukushajwa "ishaja esheshayo" yohlobo lwe-silicon 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 ukunikezwa kwamandla kwe-UPS yesekethe yokushaja enqamukile ye-voltage engaguquki, qaphela ukuthi ungalungisi i-voltage yebhethri izindawo zokuvikela eziphansi kakhulu, ngaphandle kwalokho, ijwayele ukushajwa ngokuchichima ekushajweni kwayo kokuqala.

Yiqiniso, kungcono ukusebenzisa ishaja enakho kokubili okwamanje, kanye nokucindezela okuqhubekayo. 6. 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, ukwandisa impilo yesevisi yephakethe lebhethri hhayi kuphela ukunaka ukulungiswa, kodwa futhi ucabange izici zomthwalo (ukumelana, inductance, capacitance) kanye nosayizi lapho ukhetha. Ungalenzi ibhethri lisebenze ngokugcwala ngokweqile isikhathi eside, ukuze ungagwemi ukuphuma kwebhethri.
