Transformator ya 1250 kVA ifite imbaraga zigaragara za kilovolt-amperes 1250. Mu buryo bufatika, bivuze ko ishobora gutanga 1,250.000 volt-amperes yumutwaro wamashanyarazi munsi yumubyigano wacyo, inshuro, imiterere ikonje, hamwe nibidukikije.
Nyamara, umutwaro nyawo ushobora gukoreshwa biterwa na voltage, icyiciro, imbaraga zingufu, ubwoko bwimitwaro, ubushyuhe bwibidukikije, uburyo bwo gukonjesha, imiterere yubushakashatsi, hamwe numutekano. A. 1250 kva Irashobora gushyigikira inyubako nini yubucuruzi, amahugurwa yinganda, umurongo winganda, ibikoresho byamakuru, cyangwa sisitemu yo gukwirakwiza, ariko bigomba guhuzwa neza nibisabwa n amashanyarazi.
1250 kVA isobanura iki?
Urutonde rwa kVA rwa transformateur rusobanura ubushobozi bwimbaraga zigaragara. Ihuza voltage numuyoboro udatekereje kubintu byihariye byingufu.
Inzira y'ibanze ni:
kVA = voltage x ikigezweho x icyiciro / 1000
Kuri transformateur y'ibyiciro bitatu:
kVA = 1.732 x voltage x ikigezweho / 1000
Kuri transformateur yicyiciro kimwe:
kVA = voltage x ikigezweho / 1000
Kuberako ibice byinshi binini 1250 kVA ari ibyiciro bitatu bihindura, ubushobozi bwubu busanzwe bubarwa hamwe nibice bitatu.
Nibihe bingana iki 1250 kVA ihindura Isoko?
Ibisohoka ubu biterwa na voltage ya kabiri.
Kubice bitatu-1250 kVA ihinduranya, igereranya yuzuye-yuzuye ni:
- Kuri 400V: amps hafi 1.804
- Kuri 415V: hafi 1.739 amps
- Kuri 480V: hafi 1.504 amps
- Kuri 690V: hafi 1.046 amps
- Kuri 11kV: hafi amps 66
Indangagaciro zibarwa ukoresheje ibyiciro bitatu byubu:
Ibiriho = kVA x 1000 / (1.732 x voltage)
Kurugero, kuri 400V:
1,250 x 1000 / (1.732 x 400) = hafi 1,804A
Ibi bivuze a 1250 kva Gukora kuri 400V ibyiciro bitatu birashobora gutanga ibitekerezo hafi 1,804 amps kumurimo wuzuye, ukurikije imikorere yagenwe.
Nibangahe kW ishobora gushyigikirwa na 1250 kVA?
kVA ntabwo isa na kilo. kW ipima imbaraga zakazi zukuri, mugihe kVA ipima imbaraga zigaragara. Umubano ushingiye kubintu byingufu.
Inzira ni:
kW = kVA x ibintu byingufu
Ingero:
- Kuri 1.0 power power: 1250 kWt
- Kuri 0,95 imbaraga zingufu: 1187.5 kWt
- Kuri 0.90 power power: 1125 kWt
- Kuri 0,85 imbaraga zingufu: 1062.5 kWt
- Kuri 0.80 power power: 1000 kW
Muri sisitemu nyinshi zinganda nubucuruzi, ibintu byamashanyarazi birashobora kuva kuri 0.8 kugeza 0.95 bitewe numutwaro wa moteri, drives, amatara, capacator, nibikoresho bikosora amashanyarazi.
Noneho, transformateur ya 1250 kVA irashobora gushyigikira hafi 1000 kWt kugeza kuri 1187 kWt mubikorwa byinshi bifatika, bitewe nimbaraga.
Transformer ikwiye gupakirwa 100%?
Nubwo transformateur ishobora gupimwa kubikorwa byuzuye-byuzuye, injeniyeri benshi birinda kuyikoresha ubudahwema 100% keretse igishushanyo kibyemereye. Intego ifatika yo gupakira irashobora gushiramo intera yo kwaguka kazoza, kuzamuka kwubushyuhe, imizigo ihuza, moteri itangira, nibisabwa ibihe.
Ibitekerezo rusange byateganijwe birimo:
- Ubusanzwe umutwaro uhoraho
- Icyifuzo cyo hejuru
- Gutangira icyerekezo cya moteri nini
- Kugoreka guhuza disiki cyangwa sisitemu ya UPS
- Ubushyuhe bwibidukikije
- Uburyo bukonje
- Umwanya wo guhumeka
- Gukura umutwaro
- Amategeko y’amashanyarazi
- Guhuza ibikoresho byo kurinda
Kubwigihe kirekire cyo kwizerwa, imishinga myinshi ingana na transformateur kuburyo imitwaro isanzwe ikora iguma munsi yurwego rwuzuye. Ingamba nyazo zo gupakira zigomba kugenwa nabashakashatsi babishoboye.
Ubusanzwe Porogaramu ya 1250 kVA Guhindura
Transformator ya 1250 kVA isanzwe ikoreshwa muri sisitemu y'amashanyarazi yo hagati kugeza nini.
Porogaramu zisanzwe zirimo:
- Inganda
- Parike yinganda
- Inyubako z'ubucuruzi
- Ibitaro
- Ibigo byamakuru
- Amaduka
- Ibikoresho byo gutunganya amazi
- Ibikorwa byo gucukura amabuye y'agaciro
- Imirasire y'izuba
- Sisitemu yo gukusanya ingufu z'umuyaga
- Ibikoresho binini byashizwemo
- Ikwirakwizwa
A 1250 kva Irashobora gukora ubwoko bwinshi bwimitwaro, ariko umwirondoro wumutwaro ugomba gusubirwamo mbere yo gutoranya bwa nyuma.
Ibintu bigira ingaruka kubushobozi bwumutwaro
Ikigereranyo cya voltage
Impinduka imwe kVA igipimo kizatanga indangagaciro zitandukanye zubu kuri voltage zitandukanye. Umuvuduko wo hasi bisobanura umuyaga mwinshi kuri kVA imwe.
Imbaraga
Imbaraga nke zigabanya ubushobozi bukoreshwa bwa kilo. Gukosora ibintu bishobora gufasha kunoza imikorere ya sisitemu no kugabanya ibisabwa kuri transformateur.
Uburyo bukonje
Amavuta yibizwa hamwe nubwoko bwumye birashobora kugira ibishushanyo bitandukanye. Umwuka usanzwe, umwuka uhatirwa, amavuta yumuyaga karemano karemano, cyangwa gukonjeshwa nabafana birashobora kugira ingaruka kubushobozi bwo gupakira.
Ubushyuhe
Ubushyuhe bwo hejuru bwibidukikije burashobora kugabanya ubushobozi bwo gupakira ibintu. Niba ahantu ho kwishyiriraho hashyushye cyangwa hadahumeka neza, birashobora gukenerwa.
Harmonics
Imizigo idafite umurongo nka drives ihindagurika, ikosora, sisitemu ya UPS, hamwe na LED zimwe na zimwe zirashobora gushyushya ubushyuhe. Ibi birashobora gusaba impinduka zidasanzwe cyangwa kugabanya imizigo.
Ubwoko bw'imizigo
Imizigo ya moteri, imashini zo gusudira, compressor, nibikoresho biremereye byinganda birashobora gukora amashanyarazi menshi. Transformator igomba gukora imitwaro ikora hamwe nuburyo bwo gutangira.
Nigute wahitamo 1250 kVA Transformer
Mbere yo guhitamo transformateur, abaguzi bagomba kwemeza:
- Umuvuduko wibanze
- Umuvuduko wa kabiri
- Icyiciro ninshuro
- KVA
- Ubwoko bw'imizigo
- Impamvu zingufu
- Uburyo bukonje
- Ibidukikije
- Inzu yo hanze cyangwa hanze
- Icyiciro cyo gukumira
- Impedance
- Ibisabwa neza
- Urwego rw'urusaku
- Ibisabwa byo gukingirwa
- Ibipimo bikurikizwa
- Gahunda yo kwagura ejo hazaza
Transformator igomba kandi guhuzwa na switchgear ikwiye, insinga, ibikoresho byo gukingira, sisitemu yubutaka, hamwe nigishushanyo mbonera.
Amakosa Rusange yo Kwirinda
Ikosa rimwe risanzwe nukwitiranya kVA na kW. Transformator ya 1250 kVA ntabwo buri gihe itanga 1250 kWt keretse niba ingufu ari 1.0.
Irindi kosa ni ukwirengagiza voltage. Ubushobozi buriho burahinduka cyane hagati ya 400V, 480V, na sisitemu yo hagati ya voltage.
Ikosa rya gatatu ni ugupima transformateur gusa umutwaro wuyu munsi. Niba kwaguka ejo hazaza bishoboka, igishushanyo gishobora gukenera andi marike.
Umwanzuro
Ubushobozi bwimitwaro ya 1250 kVA ihindura ni 1,250.000 volt-amperes. Ibisohoka muri iki gihe biterwa na voltage, kandi ubushobozi bwa kwayo nyabwo biterwa ningufu zingufu. Kuri 400V ibyiciro bitatu, irashobora gutanga amps 1.804. Kuri 480V ibyiciro bitatu, irashobora gutanga amps 1.504.
Mubikorwa bifatika, a 1250 kva bigomba gutoranywa no gupakururwa ukurikije voltage, ibintu byingufu, imiterere ikonje, imiterere yumutwaro, ubushyuhe bwibidukikije, ibirimo bihuza, hamwe nibikenewe byo kwaguka. Ingano ikwiye ishyigikira imikorere itekanye, gukora neza, hamwe na serivise ndende yo guhindura ubuzima.
