Transformator ya 480V ntabwo ikenera buri gihe kutabogama. Niba kutabogama bisabwa biterwa na transformateur ihinduranya, ubwoko bwimitwaro itangwa, uburyo bwo guhagarara, hamwe nuburyo bwa sisitemu y'amashanyarazi. Muri sisitemu nyinshi zinganda, ingufu za 480V zitangwa kumurongo-ku murongo nta kutabogama. Mu zindi sisitemu, cyane cyane gukwirakwiza 480Y / 277V, kutabogama birahari kandi birashobora gukenerwa kumurongo wa 277V kumurongo-utabogamye.
Niyo mpamvu igisubizo kidashobora kugabanywa kuri yego cyangwa oya. Transformator ya 480V irashobora gukora neza idafite aho ibogamiye niba itanga ibikoresho 480V gusa kumurongo. Ariko niba sisitemu igomba gutanga umurongo-utagira aho ubogamiye, kugenzura imiyoboro, gucana, cyangwa ibikoresho bivanze na voltage, transformateur irashobora gukenera ingingo idafite aho ibogamiye yagenewe guhinduranya kabiri.
Kubaguzi naba injeniyeri bahitamo a 480v icyiciro kimwe gihindura, ikibazo cyingenzi ntabwo ari igipimo cya voltage gusa. Nuburyo kandi transformateur izahuzwa, nibikoresho bizakorera, kandi niba sisitemu ya kabiri isaba umuyobozi uhagaze.
Niki Kutabogama muri sisitemu yo guhindura ibintu?
Kutabogama ni umuyoboro uhujwe na point ya neutre ya transformateur. Muri sisitemu nyinshi za AC, iyi ngingo idafite aho ibogamiye irashingwa kandi ikoreshwa nkinzira yo kugaruka kumuyoboro utaringaniye mumurongo-utabogamye.
Kutabogama ntabwo ari kimwe nuyobora ibikoresho. Ukutabogama mubisanzwe ni umutware utwara ibintu iyo umurongo-utabogamye uhujwe. Umuyoboro wibikoresho byubutaka ni umuyobozi wumutekano ugamije gutanga inzira-y-inzitizi nkeya kandi ifasha ibikoresho birinda gukora mugihe cyamakosa.
Kwitiranya kutabogama nubutaka birashobora guteza umutekano muke. Kwishyiriraho transformateur bigomba guhora byateguwe kandi bigenzurwa nabakozi bafite amashanyarazi babishoboye bakurikije code nibisabwa byaho.
Iyo Transformer ya 480V idakeneye kutabogama
Transformator ya 480V mubisanzwe ntabwo ikenera kutabogama mugihe itanga 480V gusa kumurongo-kumurongo.
Ingero zisanzwe zirimo:
- Moteri y'ibyiciro bitatu
- Imashini zinganda
- Amapompe na compressor
- Ibikoresho bya HVAC
- Ibikoresho byo gusudira
- Imirongo imwe n'imwe itanga umusaruro
- 480V igenzura ryagenewe umurongo-ku-murongo winjiza
Muri sisitemu y'ibyiciro bitatu 480V ya delta, hashobora kubaho kutabogama kuboneka. Imizigo ihujwe nuyobora icyiciro, kandi sisitemu irashobora gukora idafite umuyobozi utabogamye.
Mu buryo nk'ubwo, a 480v icyiciro kimwe gihindura irashobora guhuzwa mubice bibiri byayobora kugirango itange 480V icyiciro kimwe. Niba umutwaro usaba insinga ebyiri kuri 480V, kutabogama ntibishobora gukenerwa. Ariko, guhagarika no kurinda birenze urugero bikomeza kuba igice cyingenzi cyo kwishyiriraho umutekano.
Iyo Transformer ya 480V ikeneye kutabogama
Kutabogama birashobora gusabwa mugihe transformateur ya kabiri yashizweho kugirango itange umurongo-ku-murongo n'umurongo-utabogamye.
Urugero rusanzwe ni sisitemu ya 480Y / 277V. Muriyi miterere, voltage kumurongo-kumurongo ni 480V, mugihe umurongo-kuri-utabogamye ni 277V. Ingingo idafite aho ibogamiye ya wye ya kabiri yemerera 277V imizigo guhuzwa kuva murwego kugeza kutabogamye.
Kutabogama birashobora gukenerwa kuri:
- 277V kumurika
- Imirongo-itabogamye kugenzura imiyoboro
- Ikwirakwizwa rya voltage yo gukwirakwiza
- Sisitemu zimwe zubaka amashanyarazi
- Ibikoresho bisaba umuyobozi uhagaze
- Sisitemu ifite icyiciro kimwe cyimitwaro ihujwe kuva murwego kugeza kutabogama
Niba iyi mitwaro ihari, sisitemu yo guhindura no gukwirakwiza sisitemu igomba kuba irimo ibipimo byiza kandi byamenyekanye bitagira aho bibogamiye.
480V Delta na 480Y / 277V Wye
Imiterere ya transformateur ihinduranya ni kimwe mubintu byingenzi.
480V Delta
Impinduka ya 480V ya delta ya kabiri ifite ibyuma bitatu byayobora bihujwe na mpandeshatu ihindagurika. Sisitemu isanzwe ya delta ntabwo itanga aho ibogamiye keretse hakoreshejwe uburyo bwihariye bwo guhuza cyangwa gukoreshwa hagati.
Sisitemu ya Delta isanzwe mugukwirakwiza ingufu zinganda aho imizigo nyamukuru ari moteri nibikoresho biremereye.
480Y / 277V Wye
A 480Y / 277V wye transformateur ya kabiri ifite ibyuma bitatu bitwara kandi bitagira aho bibogamiye. Umuvuduko uri hagati yicyiciro icyo aricyo cyose ni 480V. Umuvuduko uva mu cyiciro icyo aricyo cyose uyobora utabogamye ni 277V.
Iboneza risanzwe mumazu yubucuruzi ninganda kuko irashobora gutanga ibikoresho byombi 480V hamwe na 277V kumurika cyangwa kugenzura imizigo.
A 480v icyiciro kimwe gihindura irashobora gushushanywa kubintu bitandukanye. Ibice bimwe bifite 480V yibanze na voltage yo hasi ya kabiri, nka 240V, 208V, 120V, cyangwa 24V. Abandi barashobora kugira 480V yisumbuye kubikoresho byicyiciro kimwe.
Niba ikeneye kutabogama biterwa nigishushanyo mbonera cya kabiri.
Urugero:
- 480V ya kabiri-insinga ya kabiri ntishobora gukenera kutabogama.
- Icyiciro cya 120 / 240V cyakuweho icyiciro cya kabiri kirimo kutabogama.
- Igenzura rihindura rishobora kuba rifite uruhande rumwe rushingiye ku gishushanyo cya sisitemu.
- Impinduramatwara yo kwigunga irashobora kugira icyiciro cya kabiri cyatandukanijwe kigomba kuba gishingiye kumategeko akurikizwa.
Mugihe uhitamo transformateur, abaguzi bagomba gusuzuma icyapa cyanditse, igishushanyo mbonera, ibimenyetso byanyuma, hamwe nababikoze bitonze.
Kutabogama, Impamvu, no Guhuza Biratandukanye
Isoko nyamukuru yo kwitiranya ni itandukaniro riri hagati yo kutabogama, gushingira, no guhuza.
Ukutabogama gukoreshwa muburyo busanzwe bwo kugaruka muburyo bumwe bwumuzunguruko. Grounding ihuza sisitemu cyangwa ibikoresho kwisi cyangwa sisitemu ya electrode. Guhuza bihuza ibice byayobora hamwe kuburyo ikosa rifite inzira yizewe.
Transformator ya 480V ntishobora gukenera kutabogama kubikorwa bisanzwe, ariko iracyakeneye guhagarara neza no guhuza. Inzitizi za Transformer, inzira nyabagendwa, panele, nibikoresho bihujwe bigomba guhuzwa kandi bigahinduka ukurikije ibisabwa kugirango ushyire.
Iri tandukaniro rifite akamaro kuko gukoresha imiyoboro yubutaka nkutabogamye ntabwo ari umutekano kandi mubisanzwe ntabwo byemewe muri sisitemu zisanzwe.
Ibibazo byo kubaza mbere yo guhitamo 480V Transformer
Mbere yo kugura cyangwa gushiraho transformateur, sobanura izi ngingo:
- Sisitemu ni icyiciro kimwe cyangwa ibyiciro bitatu?
- Ese transformateur yibanze ya voltage 480V?
- Ni izihe voltage ya kabiri isabwa?
- Ese imizigo umurongo-kumurongo cyangwa umurongo-utabogamye?
- Harasabwa umuzunguruko wa 277V?
- Ibikoresho bisaba umuyobozi utabogamye?
- Impinduramatwara delta, wye, cyangwa ikanda hagati?
- Transformator ni sisitemu ikomoka?
- Ni ubuhe buryo bwo gushingiraho busabwa?
- Ni ubuhe bwoko bw'amashanyarazi akoreshwa?
Kuri a 480v icyiciro kimwe gihindura, ni ngombwa cyane cyane kwemeza ibyinjijwe nibisohoka wiring. Impinduramatwara irashobora kugira igipimo cyukuri cya voltage ariko gahunda yo guhinduranya nabi kubigenewe.
Amakosa Rusange yo Kwirinda
Ikosa rimwe risanzwe ni ugutekereza ko buri 480V sisitemu ifite aho ibogamiye. Sisitemu nyinshi zinganda 480V ni sisitemu y'insinga eshatu zidafite umuyobozi utabogamye.
Irindi kosa ni ugutekereza ko ubutaka bushobora gusimbuza kutabogama. Ntishobora. Ibikoresho bifata ibyuma ntibigomba gukoreshwa nkumuyoboro usanzwe utwara ibintu.
Ikosa rya gatatu ni uguhitamo transformateur ishingiye gusa kuri voltage na kVA. Guhinduranya ibyiciro, ibyiciro byokwirinda, ubwoko bwikurikiranya, kuzamuka kwubushyuhe, inshuro, icyiciro, na gahunda ya terefone byose bishobora kugira ingaruka niba transformateur ikwiye.
Umwanzuro
Transformator ya 480V ntabwo ihita ikenera kutabogama. Niba transformateur itanga 480V gusa kumurongo-kumurongo, imitwaro ntishobora gukenerwa. Niba sisitemu itanga umurongo-utabogamye, nkumucyo wa 277V cyangwa imiyoboro runaka yo kugenzura, noneho birakenewe mubutabogamye.
Inzira yizewe yo gusubiza ikibazo nukureba kuri transformateur ihinduranya hamwe nibisabwa umutwaro. Sisitemu ya Delta ikora idafite aho ibogamiye, mugihe 480Y / 277V sisitemu ya wye irimo ingingo idafite aho ibogamiye. A. 480v icyiciro kimwe gihindura irashobora cyangwa ntishobora gusaba kutabogama bitewe nigishushanyo cyayo cya kabiri no kuyishyira mu bikorwa.
