Yiziphi izinhlobo zokuphakelwa kwamandla e-UPS ezihlukaniswa ngokwesimiso sokusebenza? Ukunikezwa kwamandla okungaphazamiseki kwe-UPS kuhlukaniswe izigaba ezintathu: ukwenza isipele, ku-inthanethi kanye ne-UPS esebenzisanayo eku-inthanethi. Ukusebenza kwamandla kagesi e-UPS ukusuka phezulu kuye phansi yilokhu: ukuguqulwa okuphindwe kabili ku-inthanethi, ukusebenzisana ku-inthanethi, uhlobo lwesipele. Inani ngokuvamile lilingana nokusebenza. Ukuqonda imodi yokusebenza yokuphakelwa kukagesi kwe-UPS kungasiza ukuvikela kangcono ukunikezwa kwamandla kwe-UPS ekunakekeleni kwansuku zonke.
Yiziphi izinhlobo zokuphakelwa kwamandla e-UPS ezihlukaniswa ngokwesimiso sokusebenza?

Ukunikezwa kwamandla kwe-UPS yilokho esivame ukukubiza ngokuthi i-UPS yamandla angaphazamiseki. Ukunikezwa kwamandla kwe-UPS kusebenza ngezindlela ezintathu ezilandelayo:

1. Umthombo wamandla we-UPS oyisipele unikezwa ngokuqondile ukusuka kumapayipi amakhulu ukuya emlayishweni lapho amapayipi amakhulu ejwayelekile. Uma amapayipi amakhulu edlula ububanzi okusebenza kwawo noma ukwehluleka kwamandla, ukunikezwa kwamandla kuguqulwa kusiguquli sebhethri ngokusebenzisa iswishi yokuguqula. Ibonakala ngesakhiwo esilula, umthamo omncane kanye nezindleko eziphansi, kodwa ububanzi bamandla kagesi okufakwayo buncane, i-voltage ephumayo izinzile futhi ukunemba akukuhle, kunesikhathi sokushintsha, futhi i-waveform yokuphumayo ngokuvamile iyigagasi lesikwele.
Isipele se-sine wave okukhipha ugesi we-UPS: ukuphuma kweyunithi kungaba ngu-0.25KW~2KW. Uma amapayipi amakhulu ashintsha phakathi kuka-170V~264V, i-UPS idlula i-170V~264V.

2. Ugesi we-UPS osebenzisanayo ku-inthanethi unikezwa ngokuqondile ukusuka kumapayipi amakhulu ukuya emlayishweni lapho ipayipi elixhumanisa livamile. Uma i-mains iphansi noma iphezulu, ulayini wokulawula ugesi wangaphakathi we-UPS uyaphuma. Uma ukunikezwa kwamandla kwe-UPS kungajwayelekile noma kucishiwe, ukunikezwa kwamandla kuguqulwa kusiguquli sebhethri ngokusebenzisa iswishi yokuguqula. Ibonakala ngebanga elibanzi lokufaka i-voltage, umsindo ophansi, ivolumu encane nezinye izici, kodwa kukhona nesikhathi sokushintsha.
Ugesi we-UPS osebenzisanayo osebenza ku-inthanethi unomsebenzi wokuhlunga, ikhono eliqinile lokugxambukela kwedolobha, isikhathi sokuguqula esingaphansi kwama-4ms, futhi ukuphuma kwe-inverter kuyi-analog sine wave, ngakho-ke ingahlonywa ngamaseva, amarutha nezinye izinto zenethiwekhi, noma isetshenziswe ezindaweni imvelo enokhahlo yamandla.

3. Ukunikezwa kwamandla kwe-UPS eku-inthanethi, lapho i-mains ijwayelekile, i-mains inikeza i-DC voltage ku-inverter kumthwalo; lapho i-mains ingavamile, i-inverter inikwa amandla yibhethri, futhi i-inverter ihlala isesimweni sokusebenza ukuze kuqinisekiswe ukuphuma okungaphazanyiswa. Ibonakala ngebanga elibanzi kakhulu lamandla kagesi, ngokuyisisekelo asikho isikhathi sokushintsha kanye nokuzinza kwe-voltage ephumayo kanye nokunemba okuphezulu, kulungele ikakhulukazi izidingo zokuphakelwa kwamandla aphezulu, kodwa izindleko ezihambisanayo ziphezulu. Njengamanje, ugesi we-UPS onamandla angaphezu kuka-3 KVA cishe wonke ugesi we-UPS eku-inthanethi.
Isakhiwo samandla e-UPS eku-inthanethi siyinkimbinkimbi, kodwa sisebenza kahle futhi singaxazulula zonke izinkinga zokuphakelwa kwamandla, njengochungechunge lwe-PS olunezindlela ezine, olukwazi ukukhipha i-sine wave AC ehlanzekile ngokuqhubekayo ngaphandle kokuphazamiseka, futhi lungaxazulula zonke izinkinga zamandla njenge-spike. , ukukhuphuka, ukukhukhuleka kaningi; edinga ukutshalwa kwezimali okukhulu, imvamisa isetshenziswa endaweni edinga amandla emishini ebalulekile kanye nesikhungo senethiwekhi.

Izindlela ezine zokusebenza kwe-UPS UPS
Ngokuya ngesimo sokusetshenziswa, ukunikezwa kwamandla okungaphazamiseki kwe-UPS kungashintshwa kube izindlela ezine ezihlukene zokusebenza: imodi yokusebenza evamile, imodi yokusebenza kwebhethri, imodi yokusebenza yokudlula kanye nemodi yokulungisa yokudlula.

1. ukusebenza okuvamile
Ngaphansi kwezimo ezijwayelekile, umgomo wokuphakelwa kwamandla wesistimu yokuphakelwa kwamandla kagesi engaphazamiseki ye-UPS ukuguqula amandla okokufaka we-AC ukuze aqondise amandla amanje lapho idolobha livamile, bese ushaja ibhethri ukuze kusetshenziswe ukuphazamiseka kwamandla; kufanele kugcizelelwe ukuthi uhlelo lokuphakela amandla e-UPS alusebenzi lapho amandla ehluleka, uma i-voltage iphansi kakhulu noma iphezulu kakhulu, iqhuma ngokushesha ukuze kuthinte izinga lamandla okusebenza okujwayelekile kwemishini, uhlelo lwe-UPS luyasebenza. umbuso ukuhlinzeka ngogesi ozinzile futhi ohlanzekile wempahla yokulayisha.

2. Ukusebenza kwe-Bypass
Lapho i-mains ijwayelekile, lapho amandla e-UPS ebonakala egcwele ngokweqile, umyalo we-bypass (i-manual noma othomathikhi), ukushisa kwe-inverter noma ukwehluleka komshini, amandla e-UPS ngokuvamile aguqula okukhiphayo kwe-inverter ukuze kudlule okukhiphayo, okungukuthi, okuhlinzekwa ngokuqondile ngamapayipi. Njengoba isigaba sokuvama kokuphuma kwe-UPS kufanele sifane nefrikhwensi ye-mains ngesikhathi sokudlula, ubuchwepheshe bokuvumelanisa besigaba buyamukelwa ukuze kuqinisekiswe ukuthi ukuphuma kwamandla e-UPS kuvumelaniswa nefrikhwensi yamapayipi.

3. Ukulungiswa kwe-Bypass
Lapho ukunikezwa kwamandla ezimo eziphuthumayo kwe-UPS kulungiswa, ukusetha i-bypass mathupha kuqinisekisa ukunikezwa kwamandla okuvamile kwempahla yokulayisha. Lapho umsebenzi wokulungisa usuqediwe, ukunikezwa kwamandla kwe-UPS kuyaqalwa kabusha, futhi ukunikezwa kwamandla kwe-UPS kuphendukela ekusebenzeni okujwayelekile.

4. sekela ibhethri
Uma amapayipi amakhulu engajwayelekile, i-UPS izoguqula amandla akhona aqondile agcinwe kubhethri abe awamanje ashintshanayo. Ngalesi sikhathi, okokufaka kwe-inverter kuzonikezwa iphakethe lebhethri, futhi i-inverter izoqhubeka nokunikeza amandla futhi inikeze umthwalo ukuze uqhubeke nokusebenzisa ukufeza umsebenzi wokunikezwa kwamandla okuqhubekayo.
Ngenhla ukuhlukaniswa kwamandla kagesi angaphazamiseki e-UPS, ugesi we-UPS empeleni uyithuluzi elikhethekile lokuphakelwa kwamandla elisetshenziselwa ukuqinisekisa ukuphepha kwezinto zikagesi. Lapho amapayipi amakhulu esebenza ngokujwayelekile, angadlala indima yokusimamisa ingcindezi, ukuze kuqinisekiswe ukuphepha kukagesi, uma amapayipi amakhulu enqanyulwa, kuba nengozi yokuhluleka kwamandla, angaguqula amandla kagesi okuqala abe yi-voltage evamile. inani lamapayipi amakhulu okuhlinzeka ngogesi ophuthumayo.
