Inde, 30-amp ndi 50-amp transformer ntchito ndizofala. Komabe, ma transformer nthawi zambiri samasankhidwa ndi amperage okha. Amayikidwa mu volt-amperes (VA) kapena kilovolt-amperes (kVA), pamodzi ndi magetsi awo oyambira, magetsi achiwiri, gawo, ma frequency, ndi kugwiritsidwa ntchito komwe akufuna.
A 50 amp transformer kotero si chinthu chimodzi chapadziko lonse lapansi. Kukula kwake kofunikira kumasintha kwambiri kutengera mphamvu yamagetsi komanso ngati dongosololi ndi gawo limodzi kapena magawo atatu. Transformer yomwe imapereka 50 amps pa 24 volts ndi yosiyana kwambiri ndi yomwe imapereka 50 amps pa 240 volts.
Funso loyenera siliri chabe, "Kodi ndikufunika 50-amp transformer?" Ndi, "Ndi magetsi otani, gawo, mtundu wa katundu, maulendo a ntchito, ndi magetsi omwe zipangizo zanga zimafuna?"
Momwe Transformer Current Ratings Imagwirira Ntchito
Mphamvu ya Transformer imachokera ku mphamvu zowonekera.
Kwa thiransifoma ya gawo limodzi:
VA = Voltage x Panopa
Kwa transformer ya magawo atatu:
VA = Voltage x Panopa x 1.732
Chiwongolero cha kusintha kwa thiransifoma ya Schneider Electric chimagwiritsa ntchito mfundo zomwezi: gawo limodzi la VA limawerengedwa kuchokera ku ma volts ochulukitsidwa ndi ma amp, pomwe magawo atatu a VA amaphatikizanso muzu wazinthu zitatu. Fomula yaposachedwa ya Schneider Electric imafotokozanso momwe VA, voliyumu, ndi gawo zimadziwira ma transformer apano.
Izi zikutanthauza kuti mulingo womwewo wapano ungafunike ma transfoma osiyanasiyana pamagetsi osiyanasiyana.
Kodi Size Transformer Imafunika Kuti 50 Amps?
Gome ili m'munsili likuwonetsa zitsanzo za kuchuluka kwa katundu. Zitsanzozi ndi za mafanizo oyambira; Kusankhidwa kwa zida komaliza kuyenera kuganizira za inrush pano, kutsitsa kosalekeza, chitetezo, kutentha, mikhalidwe yoyika, ndi manambala amagetsi omwe amagwiritsidwa ntchito.
| Kukonzekera Kotulutsa | Kuthekera kwa Transformer |
|---|
| 12 V, gawo limodzi, 50 A | Mtengo wa 600VA |
| 24 V, gawo limodzi, 50 A | 1.2 kVA |
| 48 V, gawo limodzi, 50 A | 2.4 kVA |
| 120 V, gawo limodzi, 50 A | 6 kVA pa |
| 240 V, gawo limodzi, 50 A | 12 kVA pa |
| 480 V, magawo atatu, 50 A | Pafupifupi 41.6 kVA |
Mwachitsanzo, gawo limodzi la 240 V 50 amp transformer imafunika pafupifupi 12,000 VA, kapena 12 kVA, pamlingo wokwanira. Mosiyana ndi izi, thiransifoma ya 24 V yopereka ma amp 50 ikufunika 1,200 VA yokha, kapena 1.2 kVA.
Ichi ndichifukwa chake magetsi ayenera kufotokozedwa nthawi zonse pokambirana za transformer yamakono.
Nanga Bwanji 30-Amp Transformer?
Mfundo yomweyi imagwiranso ntchito pamapulogalamu a 30-amp.
Transformer ya 30-amp ingakhale yaying'ono kwambiri pamagetsi otsika kapena yokulirapo pamagetsi apamwamba. Mwachitsanzo:
- 24 V pa 30 A imafuna za 720 VA.
- 120 V pa 30 A imafuna pafupifupi 3.6 kVA.
- 240 V pa 30 A imafuna pafupifupi 7.2 kVA.
- 480 V magawo atatu pa 30 A amafuna pafupifupi 24.9 kVA.
Wopereka katundu atha kufotokozera zida potengera mphamvu yamagetsi inayake, koma dzinalo liyenera kuwonetsanso kuchuluka kwa VA kapena kVA, voliyumu yayikulu, magetsi achiwiri, gawo, ma frequency, komanso kuchuluka kwa kutentha.
Mapulogalamu Wamba a 30-Amp ndi 50-Amp Transformers
Transformers mumtunduwu atha kugwiritsidwa ntchito m'njira zosiyanasiyana, kuphatikiza:
- Magawo owongolera mafakitale
- Zida zamakina ndi zida zamagetsi
- Njira zowunikira zotsika kwambiri
- Mabwalo owongolera a HVAC
- Makina opangira mabatire
- Mapampu, mafani, ndi zowongolera zokhudzana ndi mota
- Zida zamalonda zokhala ndi magetsi okwera kapena otsika
- Kugawa kwanyumba komanso kugwiritsa ntchito magetsi kwapadera
Mtundu wa transformer uyenera kufanana ndi kugwiritsa ntchito. Chosinthira chaching'ono chowongolera sichimalola chosinthira chogawa, ndipo chosinthira chomwe chimapangidwira kuti chiziwongoleredwa pakanthawi kochepa sichingakhale choyenera pautumiki wopitilira apo.
Kodi Ndi Zotani Zomwe Muyenera Kupereka Pofunsira Matchulidwe?
Kuti mupeze chosinthira cholondola cha 30-amp kapena 50 amp, perekani zofunikira zonse osati mtengo wokhawokha.
Zambiri zikuphatikiza:
- Mphamvu yamagetsi yoyambira
- Secondary linanena bungwe voteji
- Kusintha kwa gawo limodzi kapena magawo atatu
- Zofunika linanena bungwe panopa
- Kufunika kwa VA kapena kVA
- pafupipafupi, monga 50 Hz kapena 60 Hz
- Mtundu wa katundu, kuphatikizapo katundu wotsutsa, wochititsa chidwi, wamagetsi, kapena wokhudzana ndi galimoto
- Malo oyika m'nyumba kapena kunja
- Kudzipatula, kukwera mmwamba, kutsika, kapena kuwongolera-transformer zofunika
- Enclosure ndi kukwera zofunika
- Miyezo yogwiritsidwa ntchito, ziphaso, ndi zofunikira zamakhodi amagetsi
Pazantchito zamafakitale, ogula akuyeneranso kutsimikizira ngati thiransifoma iyenera kunyamula ma inrush apamwamba kwambiri kuchokera ku ma contactor, solenoids, motors, kapena katundu wina wowonjezera.
Osasokoneza 50 VA Ndi 50 Amps
Mmodzi pafupipafupi gwero la chisokonezo ndi kusiyana pakati 50 VA ndi 50 ampe.
Transformer ya 50 VA ndi chosinthira chaching'ono. Pa 24 V, pafupifupi pakali pano ndi:
50 VA / 24 V = 2.08 A
Sichitha kupereka ma 50 amps pa 24 V. Kuti apereke 50 amps pa 24 V, transformer ingafunike pafupifupi 1,200 VA isanayambe kuganizira malire a mapangidwe ndi zochitika zenizeni zogwirira ntchito.
Nthawi zonse fufuzani mavoti a nameplate mosamala. Cholemberacho chizindikiritse kuchuluka kwa VA kapena kVA komanso mphamvu yamagetsi ndi mayendedwe apano a mbali zoyambira ndi zachiwiri.
Kuganizira za Chitetezo ndi Kuyika
Transformer sizing ndi gawo limodzi lokha la mapangidwe amagetsi. Makondakitala, zolumikizira, ma fuse, zowononga madera, zoyambira pansi, mtundu wa mpanda, kuchuluka kwafupipafupi, ndi chitetezo chopitilira muyeso ziyeneranso kusankhidwa moyenera.
Osasankha a 50 amp transformer kokha chifukwa dera lakumunsi lamtsinje limagwiritsa ntchito 50-amp breaker. Mphamvu ya thiransifoma ndi zofunikira zachitetezo ziyenera kuwunikiridwa ngati gawo lamagetsi athunthu ndi katswiri wamagetsi wodziwa bwino komanso molingana ndi malamulo amderalo.
Malingaliro Omaliza
Inde, mayankho a 30-amp ndi 50-amp transformer alipo, koma amperage okha samatanthawuza chosinthira cholondola. Kukula kofunikira kumadalira mphamvu yamagetsi, gawo, VA kapena kVA, mawonekedwe a katundu, malo ogwirira ntchito, ndi zofunikira zachitetezo.
Kuti musankhe molondola, yambani ndi mphamvu yamagetsi ndi zofunikira pakalipano, werengerani mphamvu yowonekera, kenako sankhani thiransifoma yomwe imakwaniritsa zofunikira zonse zamagetsi. Njirayi imathandizira kupeŵa kucheperachepera, kutenthedwa, maulendo osokonekera, komanso kusintha kokwera mtengo.
