Izisifundo Esikhulu Sokulinganisa Uma Kufundiswa Amasistimu Ama-UPS Esebenza Emithambo

Izidinga ezibhekene ne-UPS kumlinganiselo wokusebenza kubizwa ngaphezu kwazo zezidinga zokusebenza kumlinganiselo wokuthengisa, njengekhemikhali, isithuthi sokuhlanza amanzi esigodlo, umgqa wokwenza izinkampani zokuphatha izinsiza, noma isistimu yokulinda ukuvula. Iziphumo zokukhetha i-UPS engafanele ayikho kuphela ukungabi nesiphumo, kodwa futhi ukungabi nokusebenza, ukwakhiwa kwamathilasi, nokuthi abantu bakhwelelwe ngokwesikhathi esihle, ubucibi, izimali ezingaphansi, noma izinkinga zokuphatha izinto ngokuphelele. Kwa-WTHD, sizobala izinkampani zokusebenza ezihle, zonke-ku-nye, okuzokufunda lezi zinkinga ezihle. Loku nguqo lomlando olunye olufanele ukubhekana nalo xa uthenga i-UPS yomlinganiselo wokusebenza.

Ukukhala kwe-UPS , I-Faktor Yekhile, Nokufaneleka Kwesilinganiso

Amandla kungabhalwa ngama-kilovolt-ampere (kVA) futhi yindlela eyokuqala yokubheka xa uyakubheka ukukhetha i-UPS, kodwa abasebenzi bemilinganiselo wokusebenza akakwazi ukuzinikela ngokwamanje ama-kilovolt-ampere. Ukukhala kubhalwa ngama-kVA futhi ngama-kilowatt (kW) futhi isilinganiso phakathi kwezi zimbili zokukhala kubizwa ngokuthi isiphakathi sesikhundla (PF) . Kungakanani okukhulu kwe-kVA, uma imotora yamandulo, izinhlangano zokuhambisa noma izinkampani zokufaka izinkampani ziyadinga i-90 kW, i-UPS izoba yisikhundla ngokuthumela umthelela.

Izinhlangano zasezindustri zanamuhla zihlukahlukene. Umthelela wokuphuma kwe-VFDs, amapampu nama-compressors ungahlinzeka, okongena kwezilingo zokubonakala kwesiphakathi se-UPS. I-WTHD isho ukusebenzisa izinhlangano ze-UPS ezinayo isiphakathi sesikhundla sokuphepha (1.0 PF) noma isiphakathi esikhulu sesikhundla sokulungisa ukuze uthole umthelela wokuphepha we-UPS yakho. Funa futhi isiphakathi sesikhundla esibhekise kumthelela wokuphuma okuphakathi kwe-RMS. Izisiphakathi zesikhundla zokulingana ne-3:1 noma kude kakhulu kuzodingeka kwezinhlangano zasezindustri ozinazo umthelela omkhulu wokuphuma (njengoko kunezimotora ezingaphezulu ekususwini). Lezi zilungile kakhulu kuma-UPS athisha ngoba zinayo iziphakathi zokuphuma zokulungisa ukuthi akhange kubekwa phansi ngokuphatha kwezinhlangano eziningi, njengoko kunezinhlangano zokuvula noma izinhlangano zokugcina umthelela.

Ukufanana kwezinhlangano kufaka phakathi kwezinye izinkundla zokusebenza ngokuthi zihambisane nezinkinga zokusebenza ngokuphambuka noma ngokuhlala emuva kwezinkinga zokusebenza ngaphandle kokuthi kubekwe isikhundla sokusebenza kwe-UPS. Abaningi abasika amakhompyutha bakhuluma ngokusebenza kahle kuphela ngokuphambuka kwezinkinga zokusebenza, kodwa izilwanyana ezisebenzisa kwi-industri ziyasebenza ngokuphambuka kwezinkinga zokusebenza ngokushesha kakhulu. Amasayensi ase-WTHD ayahlola iprofile yakho yezilwanyana—njengoko kuyisibonelo, ukusukela kwamandla, ukusebenza kwezilwanyana ngokuphambuka kwezinkinga zokusebenza, nokuhambisana kwezinkinga zokusebenza—ukuzodetermine isikhundla esizosiza ukusebenza ngokuphelele (ngokujwayelekile 125% – 150% yezilwanyana ezenzekayo) ngaphandle kokuthi kubekwe isikhundla esikhulu kakhulu futhi sithintwe isikhundla esisodwa.

Isikhundla sokusebenza kwebhatari, Isifunda Sokusebenza, Nokuphelele Kwamandla

Isikhundla sokusebenza kwebhatari yisibonelo esibonakalayo kakhulu, kodwa isebenza ngokungafanele kakhulu. Isikhundla sokusebenza asikho ngokuphelele futhi sivumela ukuthi kubhekwe ngokuphambuka kwezilwanyana, ibhatari, isikhathi, nokwengeza. Ukusebenza kahle kwezikhundla eziningi kuyadingeka kakhulu kwi-industri: iminithi eyisi-15 ukugcina ngokuphambuka kwezilwanyana, iminithi eyisi-30 ukususa izimboni zokusebenza kahle, futhi iminithi eyi-2+ ngokuphambuka kwezilwanyana eziningi ezisemthwakathini okungakwazi ukuthi kubhekwe ngokuphambuka kwezilwanyana.

Uma kubhekana izisitemu zesithuthi sezimfundo, bheka uhlobo lwe- ukwakheka Kwekhemikhali bathumela. Izibhateri zase-Valve-regulated lead-acid (VRLA) ziyasebenza kakhulu kuzimfundo ezincane, izibhateri zase-lithium ion zinika umkhawulo wemandla omkhulu, ubude bekhaya lokusebenza nokusebenza okuhle kumahlaya apho amaphuzu ayakhala, kuyasebenzela kwezindawo zokusebenza ezingakwazi ukususa amaphuzu. I-WTHD inikeza izicabhu zebhateri ezinokugcinwa ngokwezinye nezinkambo zebhateri zase-lithium-ion ezinokufakwa, okunika umbono wokuphatha ubude bekhaya ngaphandle kokuphatha isithuthi sezimfundo.

Isimo yisho indlela esithuthi sezimfundo sibhakha kumthombo wamandla. Kunezinhlobo ezintathu eziphambili:

Offline/Standby – ukulungisa amaphuzu angempela, kubhakisha amasethingi angakwazi ukuthi aqondile.

Line-interactive – ukulungisa amaphuzu nesikhundla sokulungisa, kufound kwezindawo zokusebenza ezincane.

Online double-conversion – isilungise amaphuzu ngokuphansi kwe-AC ngokuphansi kwe-AC, inika ukukhathazeka kakhulu ngokuphansi kwe-grid noise. Kuyinto eyodwa eyodwa yezindawo zokusebenza apho ukuthi ukuthinteka kwe-millisecond akukho kubalulekile.

Izisolution zezindustria zomkhosi we-UPS ezinikwa ngu-WTHD ziyasebenzisa i-online double-conversion ne-technology yama-IGBT eziyenzelwe ngokusebenzisa i-DSP, okunika umphumo wokuphakama kwe-sine wave futhi ukuthintana okungaphezu kwe-zero.

Ukungena Okuphakade kuyisisekelo esikhulu, ikakhulu kubabili abaningi bezindustria abasebenza ngamahora asezansi. Izisystem ze-UPS zezindustria zisebenza ngokusebenza kwe-92–94% futhi izilipha zokusebenza kwe-6–8% kwezindlela zokufaka njengokuphakama kwezinto kuzokubiza izindlela zokuvula. Izifunda zokungafakwa kwemithambo futhi ukusebenza kwe-Eco-mode okuhle ngu-WTHD kusinika ukusebenza kwe-97% kumazindlela amaningi. Lokho okukhulu kwe-3–5% okungabizwa ngokuthintana kwezindlela kusinika imali engaphezu kwezinkulungwane zemalithu ngonyaka kumfundo wokusebenza kwe-500 kW futhi kunciphisa isibonelo se-carbon sesikhulu, okuyisisekelo esikhulu kubabili abasha bokusebenza kwezimali.

Amathuba okufaka nokuthola kwezindustria

Izisystem ze-UPS zezindustria kufanele zisebenze emizimba engabi ngezinye zokusebenza kwezindawo zokufaka futhi isibonelo sokufaka siyisisekelo esikhulu. Amapharamitha amakhulu ahlukene:

Isilawu Sesihlangene – Isibonelo sokufana kakhulu (njengoko kungaba yini ±20% noma kude kahle) sivumela ukuthi ubhathari liyakhaqa futhi liyaphambana lapho umkhosi wokusebenza uyaphakama kakhulu, okubhekwa ngokuvamile ezingxenye eziqondile noma ezingxenye eziphezulu kwezindustria.

Isilinganiso sesikhathi sokufaka – Amageneretha wezindustria ayisemthwakisi kakhulu ngokufana kwezikhathi; i-UPS enesilinganiso esikhulu sesikhathi (njengoko kungaba yini 40 ku-70 Hz) ayizange ibe yinkululeko yokukhala ubhathari ngokungafanele.

Isilinganiso sesikhathi sokufaka nokuthwasa kwe-THD – I-THD encane (THD < 5%) nokuthwasa okuphezulu (kufana ne-1.0) kusivumela ukuthi i-UPS ayikwazi ukuthwasa umkhosi wokusebenza ophambili, kuyafana nezindlela zesi-IEEE 519.

Kwisebenzi isandla sokuphuma , bheka ngokuthi:

Ukuthwasa kwesikhathi sokuphuma – Izinhlangano zezindustria mhlawumbi kufune isilinganiso esiphezulu (kufana ne-±1% noma ngapansi kwalokho) ukuze ukuthintana okungafanele kanye nokusebenza okungafanele kuzokhala.

I-THD yokuphuma - Kusetyenziswa kwezinkambo ezingenakwazi ukuthi zihlukane kanye ne-PLCs, i-THD yokuphuma, amandla amhle (THD < 3% kumalungu okuphambili) ayikho konke. Ukufiltara okuhle kuka-WTHD kuyavumela ukuthi amandla akhululekile kwezinhloko, izinsiza, kanye nezinhloko zokudirekta ngaphandle kokuhlukana.

Ukuqhubeka kwezinkinga – Uma kusetshenziswa embonini yezindustria, i-UPS kufanele ibe nemiphumela yokuzimisa kwezinkinga ezinye (njengokuzimisa kwezinhloko). Qiniseka ukuthi ubheke izidingo njenge-125% yezinkinga ngemizuzu eyishumi noma 150% yezinkinga ngemzuzu oyodwa. Kwenziwe kakhulu ngokubusa kwezinkinga zokuchitha ukuze zibhekisele lezi zinkinga eziningi.

Ukubuyela kanye nokuhlela – Ukubuyela kwesikhathi esifanayo kanye nokubuyela okufanayo kwezinkambo zokuhlela kuvumela ukuguqula ngokushesha kwezinkambo zokusebenza ngokugcina isikhathi sokungasebenzi – okuyisisekelo sokusebenza kwezindustria ngokuphambili.

Futhi, izidingo zokugcina umhlaba kubalula. i-WTHD inakho amaphetha okungahleli ekhaya okunokwenzela ukuthi abe nesibonelo se-IP20 kuya ku-IP54, isilinganiso sesikhathi sokusebenza esihle esiphakathi kwe-10℃ kuya ku-50℃, i-PCBs eziyisilungu zokufaka izinto ezinamandla zokuphatha izithuthi nezilwane zokukhanya, okuyakusiza ukuthi ibe yinkimbinkimbi yokusebenza emaphakathini amahle okanye emaphakathini amahle asekhaya.

Isiphetho

I-UPS yasezindustria ayiyi into yokuthenga kuphela, kodwa ngumqondo wokwenza izinqumo zokusebenza okunokubangela iziphumo eziningi zokusebenza nezokufinyelela kwezimali. Konke okuthi kubhalwe kubhekwa ngokuchaza ngokuphelele kwezidingo zakho zokusebenza, kusukela kwezinhloko zokusebenza nezinhloko zokusebenza kuya kuzinhloko zokusebenza, isimo sokusebenza, nokuthi kuyisiphi isikhundla sokusebenza nezinhloko zokusebenza.

Ku-WTHD, siyisebenzisa izindlela zethu zokuthuthukisa ubunzima bezintshukumo ezintsha ngokusebenzisa iqembu elithile lokusebenza ngokugcina isikhathi eside. Uma ungenwe kubhidi yokuthuthukisa imithombo yezinsizakwane emazweni amaningi, noma udinga ukuthuthukisa kwe-OEM/ODM kwezinhlelo zokuzisa izibhambo zokuphatha amandla nezinkampani zokugcina amandla, isikhundla sokuthuthukisa kuze kube yisiphelo sokuthuthukisa kusiza ukuthi isikhundla sakho sokuthuthukisa amandla se-industri sibe senzakwane esingapheliyo, esihle kakhulu, nokwakha kakhulu. Yilapho uWTHD futhi uyisebenzise indistri yakho ngokushesha.
