Izinkampani zokuphatha amandla azigcina kuzo nje izwe elithile noma ukugcina kwesistimu yomkhumbulo ngokwesikhathi esisodwa sasezwe zonke. Umthengisi wamazwe amaningi ungathola izinkampani e-Europe (50Hz), uqalele kumkhumbulo waseNorth America (60Hz) futhi emva kwalokho uhambe iziprodukthi zokugcina e-Asia (50Hz noma 60Hz, ngokwesifunda). Isiphumo sokuphakanyiswa kwezinto zonke zokufana ngokwesibonelo kuyisibonelo esincane kakhulu: isibalo sokuqala . Ukungakhathalisi ukubili kwe-frequency kungabangela ukungafanele kakhulu, izimoto zisebenza ngokugula okungafanele, izikhombi zokugula azisebenzi, noma izinkampani zezempilo noma zezimali ezingenakwazi ukusebenza. Kwa-WTHD, sibhala iziphumo zesithuthi sokuphatha amandla okuqondile ukuze zihambisane nezinye zonke i-borders nezinye zonke i-frequencies ezizweni. Kungani ukubili kwe-frequency kubalulekile, futhi kungani kufanele kufanywa?
Ukuqonda i-50Hz ne-60Hz Izidingo ze-UPS
I-Frequency (Hz) yindlela yokubala kweziquketho zase-AC ozizwe zonke zokuzalwa ngomzuzu. Kunezindilinga ezimbili kuphela ezizweni: 50Hz e-Europe, e-Asia, e-Africa ne-Australia; futhi 60hz e-North America (e-Japan ne-South America). Lokhu akuyi qembu lelizwe; kuyisibonelo sezinhlobo nezinhlobo zezinguquko zezigenerators zasemva. Izimplications zokubili kwezinkampani zokugxilwa kubalulekile kakhulu, noma kunjalo.
Amathilika nezinkampani zokugcina amandla ziyaphatha ngokuphatha kwe-frequency. Umoto we-60Hz osebenzisa umthombo we-50Hz uyasebenza ngokushisa kwesikhathi esingama-17%, uyasebenzisa inkulungwane yamandla angaphezulu futhi uyagcina amandla ngokuphakeme. Ngaphandle kwalokho, uma izinkampani zokugcina amandla ziyasebenza ngokuphatha kwe-50Hz kodwa umthombo uyasebenza ngokuphatha kwe-60Hz, amathilika ayakwazi ukufaka amandla angaphezulu futhi ayakwazi ukusebenza ngokuphelele futhi ayakwazi ukubona ukungafanele. Ukuphatha kwe-frequency kusetyenziswa njengesikhathi sokuziphatha, futhi ukukhangelwa kuyakubiza ukungafanele kwezindaba noma ukungafanele kwezinhlelo zokusebenza ezisemthambeni, njengezinhlelo zokubhala izithombe zezempilo, izixhobo zokuzimisa ngokuphelele, nezinhlelo zokusebenza kwezimali.
Isinyathelo sokuqala xa ushiyela i-UPS yikuthola isicelo se-frequency sesilayida kunezinkulu izinkampani ezizimele (isibonelo, 50/60Hz), kodwa amashini amaningi e-industri ayizimele kwe-freqwensi. Ngaphambi kokuthenga i-UPS, i-WTHD ithemba ukuthi uhlale ujonge amaphepha esihloko seziphakamiso noma imithombo yezinhlelo zokuphatha. Amaphetha okufunda i-freqwensi kwenkundla kungakhelwa ngabantu base-engineering bethu ukuqonda i-freqwensi yokusebenza kwesikhundla sakho, okungaba yisikhundla sokusebenza kwe-freqwensi emibili, njengalokho kwezikhundla zezindustria zezizwe eziningi lapho amalayini okuproducwa akhululwa futhi abasebenza kwe-freqwensi ezinye.
Ukubambisana kwe-freqwensi yomshinisi we-UPS ne-grid nezimali ezingcono
Umshinisi we-UPS wahlala phakathi kwe-grid yomthombo wokusebenza nezimali. I-freqwensi yokuhlanganisa kwe-UPS kufanele ibe yisibonelo sesifunda esifunekayo ngazo zimali; i-freqwensi yokungena kwe-UPS kufanele isibonelo sesifunda semkhakha yomthombo wokusebenza, kodwa akukho mhlawumbi lokhu.
Isimo sokuqala: I-grid nezimali ziyasebenza ngofreqwensi oyidinganayo (isibonelo, i-grid ye-50Hz, izimali ze-50Hz) lokhu ke isimo esincane kakhulu. I-UPS esincane, eyayisebenza ngokuthi ithakhele ifreqwensi yokuvala, umsebenzi wokufana nge-47‑53Hz, uyasebenza kahle. I-UPS yasekhaya yomlando wezibalo zika-WTHD yisigaba sesibili sokuguqula, eyayisola izinqamuzi kusukela kwe-grid yokugcina nokuhlanganisa ngokuphelele nesikhathi sokusebenza futhi iyagenerate ifreqwensi yama-50Hz.
Isimo B: Ifreqwensi yegrid iyahluka kwe-freqwensi yezinqamuzi lokhu kubhekwa kakhulu emazweni angaphandle. Umzekelo, indawo yezindaba (data center) inokunako izinkampani ezavela e-60Hz, noma umthengisi unokufaka izinkampani ezavela e-Europe emadatashentha e-USA. Uma lokhu kuyisimo, kufuneka i-UPS yokuguqula ifreqwensi eyaguqula ifreqwensi yama-60Hz yokuvala yase-AC ku-DC emva kwalokho ukuze yaguqule kuma-50Hz yase-AC (noma ngokuvuliwe). Uma ufuna i-UPS eyayinika izinkampani yakho ifreqwensi esifanayo nesifreqwensi se-grid yamanzi, noma eyayinika ifreqwensi okufunekayo ngazo izinkampani zakho, u-WTHD unakunika i-UPS eyayifanele kumlando wakho.
Isimo se-C: Amaphakathi enkulu nezinkinga zokusebenza ngemikhakha eyodwa . Izingxenye ezinye zezindawo zisebenzisa izinkampani ngemikhakha yezinkulungwane eziyodwa (50 ne-60Hz). Kumaqhezu okusuka kwezinqamuzi ezimbili noma amaqhezu amaningi we-UPS okuhlanganiswa ngemikhakha eyodwa, i-WTHD inombolo yokuphatha umthelela wokusebenza ngokuphelele ukuze iphathelwe konke. Lokhu kwenza ukuthi kubizwa ngokuthi kuyisivumelwano esihle kakhulu ngokuthi kususa imali yokuqala nokuphatha kwezinkampani zokusebenza ngokwesibini.
Ukuvikela Izinkinga Zokufanana Kwemithombo YaseNingizani
Imithombo yaseNingizani iyinika izinkinga eziningi zokusebenza ngemikhakha. Lezi zingqondi kakhulu futhi lokhu kukuthi i-WTHD isinika indlela yokuvikela kona:
Ingqondi 1: Ukuthi "yonke" ibizwa ngokuthi "ngemikhakha eyodwa." Indoda eyinkulu kakhulu yokuqeqeshwa kwisibonelo sesi-50/60Hz. Ababuyeli abaningi bakhuluma nge-UPS yabo njengeyayikwamukelwa ngokuphelele kwi-50/60Hz, kodwa lokhu kuyizinkinga zokubona ukuthi kungani, ngoba isiphumo singaba sefrequensi esithile. Sicela uvumelanise uma i-UPS ingakwazi ukuthumela amafrequensi amabili ngokwezimali zayo okanye uma kufanele ikhutshwe ukusuka kwezimali xa kushintsha ifrequensi. Amamodeli e-dual frequency kwa-WTHD ayathumela izimali zazo zonke ngokuphelele kwi-50Hz futhi kwi-60Hz, futhi azinakuhlelwa ngaphandle ngokusebenzisa isikhombi sesikhondlo, okunquma ukuzinga.
Isimo esingasemthethweni 2: Ukungakhathalisi ukuthi ubuyeli bukhathalelwe . Ngemva kokuhlukaniswa komsebenzi noma emva kokugcina, i-UPS ibuyela ku-bypass esihambisana ngokugcina nesiqu ezindaweni zomkhosi wokusebenza. Kube yisibuyeli sesandla, uma ifrequensi yomsebenzi yilu-50Hz futhi ifrequensi yomkhosi yilu-60Hz, umsebenzi wakho uzosha ngafrequensi engafanele. Sisolve lokhu ngokusebenzisa ubuyeli obangafrequensi futhi izinhlelo zethu zinakuthumela okuthunyelwa kwe-inverter ngokuhambisana, futhi ukubuyisa kungasho kusebenza kwe-grid esifanayo sesikhathi noma singathola ubukhulu besikhathi esingasemthwakweni, noma singathola izindawo ezimbili zokufaka esizokwenza ukuguqula isikhathi kuzo zombili.
Isimo esingasiza: Ukuguqula kwesikhathi sokugenera. Amadloti amaningi angahlela ukuthuthuka kwesikhathi sokugenera eminyakeni lapho amandla ayasemthwakweni, futhi amagenera angahlela ukuguqula kwesikhathi kakhulu, ikakhulu eminyakeni yezinkinga ezahlukene. I-UPS ene-window yamandla engaphezulu (49.5–50.5Hz) ingabuyela kusuka kubatteri ngokuphinda-phinda, okungahlela ukuthi ibatteri ibhaleke phambi kokuphela kwesidloti. I-UPS yethu yomnotho wezindustria yase-WTHD inenqamuzi yamandla engaqondwa (kude kuma-±10%) ukubuyeza ukuguqula kwesikhathi sokugenera futhi ukuvikela ukuthi ibatteri ibe khona kuma-‘imiphumela eminingi’. Ngaphezu kwalokho, sithunyela izinkomo zokuthuthuka kwegenera ukunciphisa ukuguqula kwesikhathi kwezinkinga futhi ukuvikela ukuguqula kwesikhathi.
Isiphetho
Ukuhambanana kwe-freqwensi akuyi mbono yezinto zokusebenza ephakeme, kodwa ngumfanekiso wokusebenza okunzima okungakhathalisi umkhakha wakho we-UPS. Konke okuthetha kuleli qembu liyaphakanyiswa ngaleli pharamitha, kusukela emizini yezinto ezinkulu njenge-50Hz noma 60Hz, ukulandela izinkinga zemvelo nezinkinga zokusebenza futhi ukuzibula izinkinga zemithambo yasezweni.
Ngoba sithu kwezindustria zokusebenza kwezindlela zokuphatha izinsiza, siyabhisela amasistimu we-UPS, amasistimu wezindlela zokubeka amandla, amasistimu we-solar inverters nezinye izinhlelo zokugcina amandla ozokufaka kulezi zinhlelo zokusebenza kwezizwe zonke. Sifaka isikhundla sokuhlinzekwa kwezizwe zonke. Umsebenzi wethu wokudesigna kuya kufika ekugcineni kuyagcinwa ukuthi ukuhambanana kwe-freqwensi kuyisibonelo esikhethekileyo, na kumaqembu ayezizwe zonke noma kumaqembu okukhethwa ngokwezindlela zokusebenza kwe-OEM/ODM. Isikhundla sakho sokubeka amandla kungahlinzeki kwezizwe, njengoba amandla ayihlinzeki. Khetha i-WTHD ukuthola ukubeka amandla okuphepha nokuthi kuyisibonelo esihlinzekileyo sokubeka amandla.
