Ukukhetha iiTransformers zeZiko leDatha

Ngexesha lotshintsho lwedijithali, amaziko edatha abe yintliziyo yamashishini, kwaye iitransformer zizixhobo ezibalulekileyo ezigcina le ntliziyo ibetha. Ukukhetha itransformer efanelekileyo akupheleli nje ekusetyenzisweni kwamandla kunye neendleko zokusebenza kweziko ledatha kodwa kukwachaphazela ngokuthe ngqo ukuqhubeka kweshishini kunye nokhuseleko lwedatha.

Ukukhetha ii-transformers zamaziko amakhulu edatha kufuna ukuqwalaselwa kwemigaqo emininzi equka umthamo womthwalo, ukusebenza kakuhle kunye nokusetyenziswa kwamandla, uzinzo, ukuthembeka, kunye nokuzivumelanisa nezimo. Njengezixhobo eziphambili zenkqubo yamandla, ukukhethwa kunye nokuseta ii-transformers kuchaphazela ngokuthe ngqo ukusebenza okuzinzileyo kweziko ledatha liphela.

Eli nqaku liza kuchaza izinto ezibalulekileyo ekufuneka uziqwalasele xa ukhetha ii-transformers ezifanelekileyo kwiziko ledatha ukuze zikuncede wenze izigqibo ezinolwazi.

1. Iimfuno ezikhethekileyo zeeTransformers zeZiko leDatha

Amaziko edatha aneemfuno eziphezulu kakhulu zobonelelo lwamandla. Umthwalo ngokuyintloko uquka izixhobo zolwazi lwe-elektroniki ezifana neeseva, izixhobo zokugcina, kunye nezixhobo ezincedisayo ezifana neenkqubo zomoya opholileyo kunye neenkqubo zokupholisa. Ukuze kuthintelwe ukuphazamiseka kwezixhobo zomoya opholileyo kunye nezokupholisa kwizixhobo ze-elektroniki, ii-transformers zihlala zisetwa ngokwahlukeneyo ngokweendidi ezahlukeneyo zomthwalo ngexesha loqwalaselo lwenkqubo.

Iitransformer zesikhungo sedatha ezizinikeleyo kufuneka zibe nezi mpawu zilandelayo:

Iimfuneko zokuthembeka okuphezulu: Udidi lomthwalo (udidi) kwiziko ledatha lungaphezulu kakhulu kwiNqanaba loku-1, nto leyo efuna ukuthembeka okuphezulu kakhulu kombane.

Iimfuneko Zokusebenza Kakuhle Okuphezulu: Kufuneka zihlangabezane okanye zidlule imigangatho yokusetyenziswa kakuhle kwamandla yeKlasi yoku-1.

Amandla Okuthwala Umthwalo Ogqithisileyo: Uyakwazi ukujongana nokunyuka komthwalo ngequbuliso.

Iimfuneko zoKhuseleko oluPhezulu loMlilo: Qinisekisa ukusebenza ngokukhuselekileyo kweziko ledatha.

2. Izinto ezibalulekileyo zokukhetha

2.1 Umthamo woMthwalo kunye neNqanaba loMthwalo

Ukukhetha i-transformer enomthamo owaneleyo womthwalo kubaluleke kakhulu kuba umthwalo weendawo ezinkulu zedatha udla ngokwanda xa ishishini liphuhla.

Izinga lomthwalo elifanelekileyo (umthwalo wokwenyani / umthamo olinganisiweyo) kwi-transformer yi-70%-85%, olu luluhlu lwegolide oluqatshelwayo kushishino. Izinga lomthwalo elingaphantsi kwe-70% libangela ukuba i-transformer isebenze phantsi komthwalo olula ixesha elide, kunye nokulahlekelwa ngumthwalo ongaphezulu kwe-85% okubangela ukuba i-transformer isebenze phantsi komthwalo ophantsi ixesha elide, kwaye ilahleko ezingenamthwalo zibangela inani eliphezulu kakhulu. Ngokwahlukileyo koko, izinga lomthwalo elingaphezulu kwe-85% lityhala i-transformer kufutshane nomthwalo opheleleyo, nto leyo eqinisa ukufudumeza kwe-coil kwaye inyusa kakhulu umngcipheko wokungaphumeleli.

2.2 Ukusebenza kakuhle kunye nokusetyenziswa kwamandla

Amaziko edatha amakhulu adla ngokufuna ukusebenza ixesha elide, ngoko ke ukusebenza kakuhle kweetransformer kunye nokusetyenziswa kwamandla zizinto ezibalulekileyo ekufuneka ziqwalaselwe. Iitransformer ezisebenzayo kakhulu zinokunciphisa ukusetyenziswa kwamandla kwaye ziphucule ukusetyenziswa kwamandla, zigcine iindleko zokusebenza kweziko ledatha.

Xa ukhetha i-transformer, kubalulekile ukuthelekisa kungekuphela nje ixabiso lokuthenga kodwa kunye "nokulahlekelwa ngumthwalo + ukulahlekelwa ngumthwalo." Ezi lahleko zibulala amatyala ombane angabonakaliyo kwaye, ekuhambeni kwexesha, zinokudlula kakhulu umahluko wexabiso lokuqala.

2.3 Uzinzo kunye nokuthembeka

Uzinzo lubaluleke kakhulu ngexesha lokusebenza kweziko ledatha. Ukukhetha i-transformer ezinzileyo kakhulu kunokuqinisekisa ukusebenza okuqhelekileyo kweziko ledatha, kuthintelwe ukulahleka kwedatha okanye ezinye iingxaki ezibangelwa ziingxaki ze-voltage.

Ukuthembeka ngomnye wemigangatho ebalulekileyo yokulinganisa umgangatho wezixhobo. I-transformer ethembekileyo inokuphepha ukuphazamiseka kwedatha kunye nokulahleka okubangelwa kukusilela kwezixhobo. Ukusebenza rhoqo kweziko ledatha kubalulekile kumashishini, ngoko ke ukukhetha ii-transformer ezithembekileyo nezizinzileyo kubaluleke kakhulu.

2.4 Uzinzo lweVolthi kunye nokuCinywa kweHarmonic

Iitransformer kufuneka zibe nozinzo oluphezulu lwevolthi ukuqinisekisa ukuba izixhobo zeziko ledatha zinokusebenza ngokuqhubekekayo kwaye ziphephe umonakalo ovela kutshintsho lwevolthi. Kwiziko ledatha, izixhobo ezifana neeseva kunye ne-UPS zinobuthathaka kwi-harmonics (ii-harmonics ezigqithisileyo zinokubangela ukungasebenzi kakuhle kwezixhobo). Kubalulekile ukukhetha iitransformer ezinezinga eliphantsi lokuphazamiseka kwe-harmonic (≤3%) kunye nomsebenzi wokunciphisa i-harmonic.

2.5 Ukusebenza kokusasazwa kobushushu

Njengoko izixhobo ezikwiziko ledatha elikhulu zivelisa ubushushu obuninzi ngexesha lokusebenza, ii-transformers kufuneka zibe nokusebenza kakuhle kokusasaza ubushushu ukuthintela ukungaphumeleli okubangelwa kukushisa kakhulu. Ukusasaza ubushushu kwii-transformers zeziko ledatha kusebenzisa ikakhulu indlela ye-AN/AF, oko kukuthi, ukupholisa kwendalo okuncediswa kukupholisa umoya ngokunyanzelwa.

2.6 Ukhuseleko kunye noKhuseleko lweNdalo

Amaziko edatha anamhlanje aya egxila ngakumbi kukhuseleko lokusingqongileyo kunye nokusebenza ngokukhuselekileyo. Izixhobo zokukhusela irabha ye-silicone ezisebenza kakuhle zineempawu zokutsha ze-V0-azitshi kwaye azivelisi msi unetyhefu- nto leyo eyenza ukuba zifaneleke kakhulu kwiimfuno zokhuseleko lomlilo zamaziko edatha. Ngaphezu koko, izinto eziphambili zezinto zokukhusela irabha ye-silicone yi-dimethylsiloxane kunye nezizalisi eziqhuba ubushushu, ezingenabungozi. Azinabungozi kwimpilo yabantu ngexesha leenkqubo zokuvelisa, ukusebenza, kunye nokurisayikilisha ii-transformer windings, azibandakanyi igesi yokukhupha okanye ukukhutshwa kolwelo olungcolileyo, kwaye izixhobo zinokurisayikilishwa ekupheleni komjikelo wazo wobomi.
