Unikezelo lombane olungaphazamisekiyo kumaziko okuthenga okanye ukuThengisa kufuneka kuQhubeke

Ngorhatya lwe-9 kaDisemba, i-2019, ivenkile yokuya kwiholide yeendwendwe kwindawo yokuthenga ye-Eaton Centre eToronto yaphazanyiswa yinto ebingalindelekanga. ubumnyama. Iigalari zokuthenga zaphoswa ebumnyameni, kwaye ekuphela komthombo wokukhanya yayingumthi weKrisimesi-abaninzi bakhawuleza ukuthumela ifoto yabo kwiinethiwekhi zentlalo njengento engaqondakaliyo ngokupheleleyo. Nangona kunjalo, phakathi kweetweets kwakukho ezo apho i-mysticism yachazwa ngokulula kwaye ngokulula: umthi wawuxhunywe kumandla angenakuphazamiseka. Namhlanje siza kuthetha malunga nokuba ngabaphi abaqeshi be-UPS abanokusebenzisa ukuququzelela umbane ongaphazamisekiyo kwiindawo zabo kumaziko okuthenga. Ngapha koko, ukuthenga kufuneka kuqhubeke, akunjalo?

Unikezelo lombane oluqinisekisiweyo nolungaphazanyiswa

Kodwa okokuqala, masithi kutheni isiganeko sokucima umbane kwindawo yokuthenga ye-Eaton Centre eToronto sibandakanyiwe kwisihloko senqaku. Sithetha ngamagama; le ndawo yokuthenga ayinanxibelelwano nenkampani eyenza i-Eaton. Simply Eaton yifani eqhelekileyo phakathi kwabafuduki abanetalente abafika eUnited States besuka kwiBritish Isles ekuqaleni kwenkulungwane ye-XNUMX neye-XNUMX. Enye yee-Eatons yaseka inkampani yokurhweba, yaze enye yaseka inkampani yobunjineli. Ngoku makhe sibuyele kwisihloko esiphambili.

Iziko lokuthenga liziko elintsonkothileyo malunga nokuqinisekisa unikezelo lombane oluqinisekisiweyo nolungaphazanyiswa. Njengoko usazi, ulawulo lwalo naliphi na iziko lokuthenga likulungele ukurenta indawo engenanto phantse kuye nawuphi na umqeshi, okoko nje ishishini labo likwinkundla yezomthetho. Inokufikelela kwinqanaba apho i-bakery ene-ovens zombane ezinamandla okanye ivenkile yeentlanzi ezineefriji zemizi-mveliso ibonakala ngokukhawuleza endaweni yevenkile yempahla evaliweyo. Ngamanye amazwi, umthwalo kwigridi yombane unokutshintsha rhoqo kwaye ngeendlela ezingalindelekanga.

Kwiimeko ezinjalo, kubalulekile ukwahlula phakathi konikezelo lwamandla oluqinisekisiweyo kunye nolungenakuphazamiseka.

Iqinisekisiwe luhlobo lonikezelo lwamandla apho, ukongeza kunikezelo lwamandla oluphakathi, umthombo ogciniweyo wonikezelo lwamandla oluzimeleyo lusetyenziswa (ngokuqhelekileyo iseti yejeneretha yedizili, iseti yejenereyitha yedizili). Iindawo ezinkulu zokuthenga zinokubonelelwa ziiseti ezininzi zejenereyitha yedizili. Ngonikezelo lwamandla oluqinisekisiweyo, ikhefu kunikezelo lwamandla kubathengi ukusuka kwigridi yamandla esembindini ivunyelwe kuphela ngexesha lokutshintsha okuzenzekelayo komthombo wamandla ogciniweyo (i-DGS, ijenereyitha yombane yegesi).

Ngaphandle kokuphazanyiswa unikezelo lwamandla luthatha ubukho bomthombo wesithathu ozimeleyo wamandla ngendlela ye-UPS, enika amandla abasebenzisi ixesha elifunekayo ukuqalisa i-generator yokuzimela kunye nokufikelela kumthwalo olinganisiweyo. Ngokwesiqhelo kuthatha ukuya kuthi ga kwimizuzu emi-3 ukuqalisa iiseti zejenereyitha zedizili ezinamandla; ebusika, isibanda esikuzo sihlala sifudunyezwa ukuze siqale ngokuzithemba.

Idayagram yonikezelo lwamandla olula kwiziko lokuthenga. Umthombo: oomakhulu

Njengomthetho, unikezelo lwamandla kwiziko lokuthenga lwakhiwe ngokweskimu seklasiki sokwahlula abaqeshi kunye neenkonzo zangaphakathi kwiziko lokuthenga kwiindidi ezahlukeneyo zabathengi.

• Abathengi II udidi, ezibandakanya uninzi lwabaqeshi abaqhelekileyo beziko lokuthenga, abanalo uxhulumaniso kumbane oqinisekisiweyo ovela kwiseti yejeneretha ye-diesel kwaye banokuthembela kuphela kwigridi yombane wesixeko kunye nezabo (indawo) zombane ezingenakuphazamiseka (UPS).
• Abathengi Udidi I tshintshela ngokuzenzekelayo kwijeneretha ye-diesel xa kwenzeka imeko engxamisekileyo kwiigridi zamandla esixeko, kodwa de kube isethi yejeneretha ye-diesel iqaliswe, baya kucinywa amandla. Kwaba baqeshisi, ukucinywa kombane kubalulekile kushishino okanye kukhuseleko loluntu. Kwindawo yeevenkile, abaqeshi abanjalo badla ngokubandakanya iikhemesti ezineefriji zamayeza, iiofisi zonyango kunye nezamazinyo, kunye neendawo zokuzonwabisa zabantwana.
• Abathengi I udidi olukhethekileyo fumana unikezelo lombane olungaphazanyiswa kwaye alunakucinywa nokuba lixeshana elifutshane. Kubasebenzisi abanjalo, kusetyenziswe imithombo emithathu yombane-isikhululo sedolophu kunye neseti yejeneretha ye-diesel, kwaye ngexesha lokuqalisa isethi ye-diesel generator banikwa amandla kwii-UPS zoshishino. Abasebenzisi abanjalo baquka i-alam yomlilo kunye neenkqubo zokucima umlilo ezizenzekelayo, ukhuseleko loluntu kunye neenkqubo zokulumkisa ngokukhawuleza, ukukhanya okungxamisekileyo, indawo kunye nezixhobo zenkonzo yokuthunyelwa kwindawo yokuthenga. Ukuba iinkampani ze-IT zirenta indawo kwindawo yokuthenga, ziphinda ziodole unikezelo lwamandla olungaphazamisekiyo kubo.

Ukusetyenziswa kwe-UPS yoshishino kumaziko okuthenga kudidi olukhethekileyo lwabathengi lwenziwa ngokweskimu esiphakathi. Kwesi sikimu, umbane unikezelwa ukusuka kwindawo enye kubo bonke abasebenzisi bolu didi ngaphakathi kwiziko lokuthenga.

Kubahlali abaqhelekileyo beziko lokuthenga - iivenkile, iikhefi, iindawo zokuzilolonga, iisaluni zobuhle, njl.njl., ukubonelela ngombane oqinisekisiweyo ophakathi okanye ongaphazamisekiyo unokubiza kakhulu ukhetho. Kwiimeko ezinjalo, kunokwenzeka ngokoqoqosho ukusebenzisa into ebizwa ngokuba yinkqubo yonikezelo lwamandla angaphazamisekiyo, eya kuxoxwa ngezantsi.

Iskimu se-UPS esinatyisiweyo - iingenelo kunye nokungeloncedo

Izikim zonikezelo lwamandla ezinatyisiweyo kunye nezibekwe kumbindi ongaphazamisekiyo azihambelani zodwa. Ezi zicwangciso zimbini zinokudityaniswa kwaye kufuneka zidityaniswe. Ngokomzekelo, abathengi ababalulekileyo (kunye nabo bahlawule ngokukodwa) ngaphakathi kwendawo yokuthenga bakhuselwe yi-UPS enkulu yemizi-mveliso, kodwa kwivenkile ethile engenawo amandla aqinisekisiweyo, i-UPS yezinga lokungena kunye ne-mid-range ye-UPS ingasetyenziselwa ekuhlaleni ukubonelela ngokhuseleko. iirejista zemali, iiseva, abashicileli, njl.

Makhe sijonge izinto ezilungileyo kunye nezibi zesikimu sonikezelo lwamandla olunatyisiweyo kwaye, okokuqala, malunga noncedo lokusebenzisa ii-UPS zasekhaya:

• akukho cingo lutsha lufunekayo, iindawo zokuphuma eludongeni ezikhoyo zisetyenzisiwe; Ii-UPS zendawo zilula ukuzisebenzisa kwaye zidibanise kwiirejista zemali, iikhompyutha, kunye nezinye izixhobo ezibalulekileyo; xa utshintsha indawo eqeshwayo, ezo UPS zithathwa kunye nazo kwaye zibekwe kwindawo entsha;
• I-UPS yendawo yokungena kunye ne-middle-class inexabiso eliphantsi - uhlahlo lwabiwo-mali oluphantse lwalo naliphi na ishishini elincinci linokukwazi ukuthenga ii-UPS ezinjalo - kunye namandla ukuya kwi-3000 VA ikuvumela ukuba udibanise iirejista zemali ezininzi okanye ii-PC kwi-UPS enye;
• umqeshi akabophelwanga kwinqanaba lomthwalo owabelweyo, utshintsho kwinani leerejista zemali okanye ezinye izixhobo ngenxa yokwandiswa kweshishini akuyi kufuna imvume entsha yekhontrakthi yokubonelela ngombane;
• ukuba umqeshi sele eneseti yee-UPS zakhe, ngoko kuyavakala ukuzisebenzisa kwiskim sonikezelo lwamandla olungenaziphazamiso.

Ngamanye amaxesha ulawulo lweziko lokuthenga - ngakumbi ukuba kukho umthamo wasimahla emva kokuba umqeshi ophambili ephumile - uqala ngokuqhubekayo ukunika abaqeshi ukuba baqhagamshele kuthungelwano lonikezelo lombane oluqinisekisiweyo okanye olungaphazamisekiyo kwimeko yokucima kombane kwisitishi esingaphantsi kwesixeko.

Apha kuxa kubhetele ukusebenzisa unikezelo lwamandla olusembindini olungaphazamisekiyo:

• Ukuqhubeka kweshishini kubalulekile kumqeshi (umzekelo, iikhemesti ezineekhabhathi ezifrijiweyo zamayeza, iiofisi zonyango kunye nezamazinyo, iikliniki zobuhle ezineenkqubo eziqhubekayo zomjikelo, abaqeshisi ababonelela ngeenkonzo ze-intanethi, njengeenkampani ze-IT): unikezelo lombane olungaphazanyiswa luyilelwe unikezelo olungenamda. abathengi bexesha (ngokuxhomekeke kunikezelo lwamafutha kwisethi ye-diesel generator), kunye ne-UPS yendawo inokuxhasa ukusebenza kwezixhobo kuphela ixesha elifutshane, ngokuqhelekileyo akukho ngaphezu kwemizuzu eyi-15-20, kwaye ukuba unikezelo lombane alubuyiselwa ngexesha. ngeli xesha, izixhobo kusafuneka zicinywe;
• ukuba inani le-UPS zasekhaya lidlula ishumi elinesibini, kwaye zezemodeli ezahlukeneyo kwaye zithengwe ngamaxesha ahlukeneyo, emva koko ukubeka esweni imeko yeebhetri kunye nokutshintshwa kwazo kuba yinto ephazamisayo ephawulekayo, kuba lula ukuba ungaqapheli ibhetri esele iphosakele, kwaye njengoko ngenxa yoko, i-UPS ayiyi kukwazi ukukhusela izixhobo xa kwenzeka ukusilela kwamandla;
• Xa kukho ukuphuma kombane, ii-alamu ezininzi ezivakalayo ezivela kwii-UPS zendawo zingabangela ukucaphuka kunye nokuxhalaba kwiindwendwe (umzekelo, abathengi kwiiklinikhi zobuhle).

Okulandelayo - malunga neentlobo kunye neemodeli ze-UPS ezifanelekileyo kakhulu kubaqeshi bamaziko okuthenga phakathi kwamashishini amancinci.

Iingcebiso kuhlobo kunye namandla e-UPS kubaqeshi beziko lokuthenga

Ibali malunga neentlobo ezintathu ze-UPS - i-UPS engaxhunyiwe kwi-intanethi, uhlobo lwe-line-interactive kunye ne-UPS ye-intanethi - inokufumaneka phantse kuwo onke amanqaku kwesi sihloko, kodwa awukwazi ukwenza ngaphandle kwayo ukuba unika iingcebiso ekukhetheni umbane ongenakuphazamiseka.

Izicwangciso zeentlobo ezintathu ze-UPS: a) ngaphandle kwe-intanethi, b) i-line-interactive, c) kwi-intanethi. Umthombo: Eaton

Eyona ilula kwaye inexabiso eliphantsi backup UPS (ngaphandle kwe-intanethi, i-back-UPS, i-stand-by) kwiimeko ezininzi azikhuthazwa ngenxa yokuba i-voltage enikezelwayo kwinethiwekhi isetyenziswe ngokuthe ngqo kumthwalo. Nangona i-voltage kwi-backup UPSs ihluzwa, ayilawulwa nangayiphi na indlela - ukuba kukho i-voltage ephantsi okanye ephezulu kwinethiwekhi, yiloo nto kanye eya kunikwa umthwalo.

Amandla ebhetri kwi-UPSs yogcino avulwa kuphela xa kukho ilahleko epheleleyo yamandla ombane kwigalelo, kwaye uqikelelo (uqikelelo) uhlobo lwe-voltage sine wave lunikezelwa kwisiphumo, esinesiphumo esibi ekusebenzeni kwesixhobo nge. izixhobo zombane ze-transformer, iimoto zombane, ukukrwitsha, i-Hi-Fi audio kunye nezixhobo zevidiyo , iibhoyila zokufudumeza ezineempompo zokujikeleza, iifriji kunye ne-air conditioners, iimpompo zamanzi. Akukhuthazwa ngokungqongqo ukusebenzisa ii-UPS ezigcinayo ukukhusela izixhobo zelabhoratri kunye nezixhobo zonyango, ezinokunikwa amandla ombane kuphela nge-sinusoid efanelekileyo.

Line-interactive UPS (umgca-interactive) - eyona nto isebenzayo ngokwexabiso / umgangatho womlinganiselo wonikezelo lwamandla. Umahluko obalulekileyo phakathi kwe-UPS ye-line-interactive kunye ne-UPS engaxhunyiwe kwi-intanethi kubukho be-voltage stabilizer (ekwabizwa ngokuba yi-autotransformer, i-AVR, i-Automatic Voltage Regulator). Ke ngoko, i-UPS esebenzisana nomgca iluncedo kakhulu xa isetyenziswa kwindawo apho i-voltage yegalelo inokwahluka kakhulu. I-voltage stabilization capabilities ze-UPS ezinjalo zibaluleke kakhulu - ukusuka kwi-150-160 V ukuya kwi-270-290 V kwigalelo, ngokuxhomekeke kwimodeli, ngelixa imveliso iya kuzinza i-230 V. Ii-UPS zanamhlanje ezisebenzisanayo, ezifana ne-Eaton 5P kunye Uchungechunge lwe-5PX, lunolawulo lwe-microprocessor kwaye lunikeze i-sine wave efanelekileyo yombane wokuphuma.

I-UPS ye-Intanethi (kwi-intanethi, ukuguqulwa kabini) - eyona nto ichaseneyo ne-UPS engaxhunyiwe kwi-intanethi ngokomgangatho wamandla: kungakhathaliseki ukuba i-voltage okanye ukuphazamiseka kunikezelo lwamandla, i-sine wave efanelekileyo iya kunikwa kumthwalo. Ukuguqulwa kabini kwenziwa ngaphakathi kwe-UPS - i-voltage yegalelo etshintshanayo iguqulwa ibe yi-voltage ethe ngqo, kwaye emva koko ibe yi-voltage etshintshanayo, eneparamitha ezifanelekileyo. Ukuphela kokungalunganga kwe-UPS ye-intanethi lixabiso eliphezulu.

I-Eaton icebisa le mifuziselo ilandelayo ye-UPS yonxibelelwano kubaqeshi bamaziko okuthenga:

• Ukuba izixhobo ezikhuselweyo zixhotyiswe ngentambo yokuqhagamshela kwisokethi ejikelezayo ye-Euro (i-DIN Socket Type-F), ngoko ungakhetha iimodeli ze-UPS ezisebenzisanayo ze-Eaton Ellipse ECO (amandla ukusuka kwi-500 VA ukuya kwi-1600 VA) okanye i-Eaton Ellipse PRO. (amandla avela kwi-650 VA ukuya kwi-1600 VA) - i-UPS nganye ineendawo ezine ukuya kwezisibhozo, i-voltage input ingaba kuluhlu lwe-161-284 V;

  
  Umthombo: Eaton

• ukuba ufuna ukudibanisa izixhobo kunye neentambo "zekhompyutheni" (uhlobo lwe-IEC320-C13), ngoko sinokucebisa ii-UPS ezisebenzisanayo zomgca we-5th series - iimodeli ze-Eaton 5E, 5S, 5SC - imodeli ene-sine wave eqikelelweyo, 5P, 5PX - iimodeli ezinombane ococekileyo we-sine wave kwimveliso (amandla asuka kwi-500 VA ukuya kwi-3000 VA). Iimodeli ziyahluka kwimisebenzi yenkonzo, ubukho bombonakaliso, uhlobo lwecala, ukufumaneka kweebhetri ezitshisayo; kubathengi abaneeplagi ze-Euro xa usebenzisa i-Eaton 5-series UPS, ungathenga iintambo zeadaptha IE-320 C14 / Socket Type-F;

  
  Eaton 5P line-interactive UPS enemveliso sine wave ecocekileyo. Umthombo: Eaton

Ukongeza kwinqanaba lokungena elikhankanyiweyo (i-Ellipse) kunye nemifuziselo ye-UPS ephakathi (Series 5), kumgca wemveliso ye-Eaton kukho uluhlu lwe-9 lwe-UPS ezenziwe ngokusebenzisa iteknoloji yokuguqula kabini, kunye noluhlu olubanzi lweemodeli zokukhusela iiseva zenkampani, kunye nokusebenza kumaziko edatha kunye nezixhobo zokuvelisa.

Ngenxa yoko,

Okukhona uvakalelo lweshishini lakho kukwehla kwexesha kunye nelahleko, kokukhona i-UPS ibaluleke kakhulu kulo. Ke ngoko, funda lo mbandela ngokwakho kwaye ubuze imibuzo kwizimvo kwiposti okanye kwiwebhusayithi yethu ukuba kukho into engacacanga.
