Na nso nso a, Navitas webatara CRPS 185 4.5kW AI data center ọkọnọ ike, nke na-eji.YMIN's CW3 1200uF, 450Vcapacitors. Nhọrọ nke capacitor a na-enye ohere ka ọkụ eletrik nweta ihe ike 97% na ọkara ibu. Ọganihu teknụzụ a abụghị naanị na-ebuli arụmọrụ ọkụ ọkụ mana ọ na-emekwa ka ike dị mma dịkwuo mma, ọkachasị na ibu dị ala. Mmepe a dị oke mkpa maka njikwa ike data center na nchekwa ike, n'ihi na ịrụ ọrụ nke ọma ọ bụghị naanị na-ebelata oriri ume kamakwa na-ebelata ụgwọ ọrụ.
Na usoro eletriki nke oge a, a na-eji capacitors eme ihe ọ bụghị naanị makanchekwa ikena nzacha mana na-ekerekwa òkè dị mkpa n'ịkwalite ihe ike. Ihe ike bụ ihe dị mkpa na-egosi arụmọrụ sistemu eletriki, na capacitors, dị ka ngwaọrụ dị irè maka imeziwanye ihe ike, na-enwe mmetụta dị ukwuu n'ịkwalite arụmọrụ nke sistemu eletrik. Isiokwu a ga-enyocha otú capacitors si emetụta ike ihe na-atụle ọrụ ha na ngwa ngwa.
1. Basic ụkpụrụ nke Capacitors
Capacitor bụ akụrụngwa eletrọnịkị nke nwere ndị nduzi abụọ (electrodes) na ihe mkpuchi (dielectric). Ọrụ ya bụ isi bụ ịchekwa ma hapụ ike eletrik na sekit nke dị ugbu a (AC). Mgbe AC ugbu a na-agafe na capacitor, a na-emepụta oghere eletrik n'ime capacitor, na-echekwa ike. Dị ka nke ugbu a na-agbanwe, nacapacitorna-ahapụ ike a echekwara. Ikike a ịchekwa na ịhapụ ike na-eme ka ndị na-emepụta ihe dị irè n'ịgbanwe mmekọrịta nke dị n'etiti ugbu a na voltaji, nke dị mkpa karịsịa na ijikwa akara AC.
Njirimara a nke capacitors pụtara ìhè na ngwa bara uru. Dịka ọmụmaatụ, na sekit nzacha, capacitors nwere ike igbochi Direct current (DC) ebe ha na-ahapụ akara AC ka ọ gafee, si otú a na-ebelata mkpọtụ na mgbama. Na sistemu ike, capacitors nwere ike idozi mgbanwe voltaji na sekit, na-eme ka nkwụsi ike na ntụkwasị obi nke sistemu ike.
2. Echiche nke ike ihe
Na sekit AC, ihe na-akpata ike bụ oke nke ike n'ezie (ezigbo ike) na ike pụtara ìhè. Ike n'ezie bụ ike gbanwere n'ime ọrụ bara uru na sekit, ebe ike pụtara ìhè bụ ike zuru ezu na sekit, gụnyere ma ezigbo ike na ike reactive. Enyere ihe ikike ike (PF) site na:
ebe P bụ ezigbo ike na S bụ ike pụtara ìhè. Ihe na-akpata ike sitere na 0 ruo 1, yana ụkpụrụ dị nso na 1 na-egosi arụmọrụ dị elu na ntinye ike. Ihe na-akpata ike dị elu pụtara na ọtụtụ n'ime ike na-agbanwe nke ọma ka ọ bụrụ ọrụ bara uru, ebe obere ike na-egosi na nnukwu ike na-efunahụ ike dị ka ike ọrụ.
3. Reactive Ike na ike ihe
Na sekit AC, ike reactive na-ezo aka na ike kpatara ọdịiche nke oge dị n'etiti ugbu a na voltaji. Ike a anaghị agbanwe ka ọ bụrụ ọrụ n'ezie mana ọ dị n'ihi mmetụta nchekwa ike nke inductors na capacitors. Inductor na-ewebata ike mmeghachi omume dị mma, ebe capacitors na-ewebata ike mmeghachi omume na-adịghị mma. Ọnụnọ nke ike na-emeghachi omume na-eme ka arụ ọrụ nke ọma belata na usoro ike, ebe ọ na-abawanye ibu n'ozuzu ya n'emeghị ka ọ rụọ ọrụ bara uru.
Mbelata nke ike ihe n'ozuzu na-egosi ọkwa dị elu nke ike reactive na sekit, na-eduga na mbelata n'ozuzu arụmọrụ nke usoro ike. Otu ụzọ dị irè isi belata ike na-arụ ọrụ bụ site n'ịgbakwunye capacitors, nke nwere ike inye aka melite ihe ike na, n'aka nke ya, welie arụmọrụ zuru oke nke usoro ike.
4. Mmetụta nke Capacitors na Ike Factor
Capacitors nwere ike imeziwanye ihe ike site na ibelata ike mmeghari. Mgbe a na-eji capacitors na sekit, ha nwere ike imebi ụfọdụ ike na-emeghachi omume nke ndị inductor webatara, si otú ahụ belata mkpokọta mmeghachi omume na sekit. Mmetụta a nwere ike ịba ụba nke ukwuu, na-ebute ya nso na 1, nke pụtara na arụmọrụ nke iji ike eme ihe na-eme ka ọ dịkwuo mma.
Dịka ọmụmaatụ, n'ime sistemu ike ụlọ ọrụ mmepụta ihe, enwere ike iji capacitors kwụọ ụgwọ ike na-emeghachi omume site na ibu inductive dị ka moto na transformers. Site n'ịgbakwunye capacitors kwesịrị ekwesị na usoro ahụ, enwere ike imeziwanye ihe ike ike, na-ebelata mfu ọkụ na ịba ụba nke ojiji ike.
5. Nhazi Capacitor na Ngwa bara uru
Na ngwa ndị bara uru, nhazi nke capacitors na-ejikọta ya na ọdịdị nke ibu ahụ. Maka ibu inductive (dị ka moto na transformers), enwere ike iji capacitors kwụọ ụgwọ ike arụ ọrụ ewepụtara, si otú a na-emeziwanye ihe ike. Dịka ọmụmaatụ, na sistemu ike ụlọ ọrụ mmepụta ihe, iji ụlọ akụ capacitor nwere ike ibelata ibu ọrụ ike na-arụ ọrụ na transformers na cables, na-emeziwanye arụmọrụ nnyefe ike yana ibelata mfu ọkụ.
Na gburugburu ibu dị elu dị ka ebe data data, nhazi capacitor dị mkpa karịsịa. Navitas CRPS 185 4.5kW AI data center ọkọnọ ike, dịka ọmụmaatụ, na-eji YMIN.CW31200uF, 450Vcapacitors iji nweta ihe ike 97% na ọkara ibu. Nhazi a ọ bụghị nanị na-eme ka arụmọrụ nke ike ọkụ dịkwuo elu ma na-eme ka njikwa ike zuru ezu nke etiti data. Ọganihu teknụzụ dị otú ahụ na-enyere ụlọ ọrụ data aka ibelata ụgwọ ọrụ ike nke ukwuu ma kwalite nkwado ọrụ.
6. Ọkara Ibu Ike na Capacitors
Ọkara ibu ike na-ezo aka na 50% nke ike akwadoro. N'ime ngwa bara uru, nhazi nke capacitor kwesịrị ekwesị nwere ike ịkwalite ihe ike nke ibu ahụ, si otú ahụ na-emeziwanye arụmọrụ ike na-arụ ọrụ na ọkara ibu. Dịka ọmụmaatụ, moto nwere ikike nke 1000W, ma ọ bụrụ na ejiri ya na capacitors kwesịrị ekwesị, nwere ike ịnọgide na-enwe ike dị elu ọbụna na ibu 500W, na-eme ka ike dị irè. Nke a dị mkpa karịsịa maka ngwa nwere ibu na-agbanwe agbanwe, ebe ọ na-eme ka nkwụsi ike nke ọrụ usoro ahụ dịkwuo elu.
Mmechi
Ngwa nke capacitors na sistemu eletriki abụghị naanị maka nchekwa ike na nzacha kamakwa maka imeziwanye ihe ike na ịbawanye arụmọrụ nke sistemu ike. Site n'ịhazi capacitors nke ọma, ike na-emeghachi omume nwere ike ibelata nke ukwuu, enwere ike ịkwalite ihe ike ike, yana arụmọrụ na ọnụ ahịa nke sistemụ ike nwere ike ịkwalite. Ịghọta ọrụ nke capacitors na ịhazi ha dabere na ọnọdụ ibu n'ezie bụ isi ihe na-eme ka arụmọrụ nke usoro eletrik dịkwuo mma. Ọganihu nke Navitas CRPS 185 4.5kW AI data center ọkọnọ na-egosi nnukwu ike na uru nke teknụzụ capacitor dị elu na ngwa bara uru, na-enye nghọta bara uru maka ịkwalite sistemu ike.
