Ndeupi musiyano uripo pakati pekW nekVa?
Musiyano wekutanga pakati pekW (kilowatt) uye kVA (kilovolt-ampere) ndiyo simba chinhu.kW iyuniti yesimba chairo uye kVA iyuniti yesimba rinoonekera (kana simba chairo pamwe nere-active simba).Iyo simba chinhu, kunze kwekunge ichitsanangurwa uye ichizivikanwa, saka inofungidzirwa kukosha (kazhinji 0.8), uye iyo kVA kukosha ichagara yakakwirira kupfuura kukosha kwekW.
Zvichienderana nemajenareta emaindasitiri uye ezvokutengeserana, kW inonyanya kushandiswa kana ichitaura nezvemajenareta muUnited States, uye dzimwe nyika shoma dzinoshandisa 60 Hz, nepo ruzhinji rwepasirese ruchiwanzo shandisa kVa seyakanyanya kukosha pakurevera. jenareta seti.
Kuti uwedzere pairi zvishoma, iyo kW chiyero ndiyo inokonzeresa kuburitsa simba iro jenareta rinogona kupa zvichibva pane simba rebhiza reinjini.kW inofananidzwa nechiyero chebhiza chenguva dzeinjini .746.Somuenzaniso kana uine 500 horsepower injini ine kW rating ye 373. The kilovolt-amperes (kVa) ndiyo generator kupera simba.Maseti ejenareta anowanzo kuratidzwa neaviri ratings.Kuti uone kW uye kVa reshiyo nzira iri pazasi inoshandiswa.
0.8 (pf) x 625 (kVa) = 500 kW
Chii chinonzi simba?
Iyo simba factor (pf) inowanzotsanangurwa sereshiyo pakati pekilowatts (kW) uye kilovolt amps (kVa) inotorwa kubva pamutoro wemagetsi, sezvakakurukurwa mumubvunzo uri pamusoro zvakadzama.Inotarirwa nemajenereta akabatanidzwa mutoro.Iyo pf pazita rezita rejenareta inoenderana nekVa kune kW chiyero (ona formula pamusoro).Majenareta ane simba repamusoro zvinhu zvinonyanya kuendesa simba kune yakabatana mutoro, nepo jenareta ane yakaderera simba chinhu haashande uye anokonzera kuwedzera simba mari.Chiyero chesimba chejenareta chechikamu chetatu ndicho .8.
Ndeupi musiyano uripo pakati pekumira, inoenderera, uye yepamusoro simba ratings?
Majenareta emagetsi ekumira anowanzo shandiswa mumamiriro ekukurumidzira, senge panguva yekudzima kwemagetsi.Yakanakira maapplication ane imwe yakavimbika inoenderera sosi yemagetsi senge utility simba.Zvinokurudzirwa kushandiswa kazhinji kazhinji chete kwenguva yekudzima kwemagetsi uye kugara uchiyedzwa uye kugadzirisa.
Prime power ratings inogona kutsanangurwa sekuve ne "unlimited run time", kana chaizvo jenareta iyo ichashandiswa seyakanyanya simba sosi uye kwete yekumira kana backup simba.Yekutanga simba rejenareta rinokwanisa kupa simba mumamiriro ezvinhu pasina utility sosi, sezvinowanzoitika mumaindasitiri ekushandisa semigodhi kana oiri & gasi mashandiro ari munzvimbo dziri kure uko grid isingasvikike.
Simba rinoenderera rakafanana nereprime power asi rine base base load rating.Inogona kupa simba nguva dzose kumutoro wenguva dzose, asi haina kukwanisa kubata mamiriro ekuremedza kana kushanda pamwe chete nemitoro yakasiyana.Musiyano mukuru pakati peyekutanga uye inoenderera ratings ndewekuti ekutanga simba gensets akaiswa kuti ave nesimba rakakura rinowanikwa pamutoro unochinja kwenhamba isina muganho yemaawa, uye iwo anowanzo sanganisira gumi muzana kana kuti yakawandisa kugona kwenguva pfupi.

Kana ini ndichifarira jenareta isiri iyo voltage yandinoda, voltage inogona kuchinjwa here?
Magumo ejenareta akagadzirirwa kuti angave akabatana zvakare kana kuti asina-kubatanidzwazve.Kana jenareta yakanyorwa seinogonekazve voltage inogona kuchinjwa, nokudaro kana isiri-kubatanidzwazve voltage haichinji.12-lead reconnectable generator ends inogona kuchinjwa pakati pematatu uye single phase voltages;zvisinei, ramba uchifunga kuti kushanduka kwemagetsi kubva pachikamu chetatu kuenda kune chimwe chete kunoderedza simba rekubuda kwemuchina.10 lead reconnectable inogona kushandurwa kuita matatu phase voltages asi kwete chikamu chimwe chete.

Chii chinoitwa neAutomatic Transfer Switch?
Iyo otomatiki yekuchinjisa switch (ATS) inotamisa simba kubva kune yakajairwa sosi, senge utility, kune simba rekukurumidzira, senge jenareta, kana yakajairwa sosi yatadza.Iyo ATS inonzwa kukanganiswa kwemagetsi pamutsetse uye yobva yasaina injini kuti itange.Kana iyo yakajairwa sosi yadzoserwa kune yakajairika simba iyo ATS inotamisa simba kumashure kune yakajairwa sosi uye inovhara jenareta pasi.Automatic Transfer Swichi inowanzo shandiswa munzvimbo dzinowanikwa zvakanyanya senge data centers, zvirongwa zvekugadzira, telecommunication network zvichingodaro.

Jenareta randiri kutarisa rakafanana neranditori naro?
Majenareta seti anogona kufananidzwa kune kana redundancy kana kugona zvinodiwa.Paralleling jenareta inokutendera iwe kuti ubatanidze nemagetsi kuti ubatanidze simba ravo rekubuda.Kufanana majenareta hakuzonetse asi imwe pfungwa yakakura inofanirwa kupinda mune yakazara dhizaini zvichibva pachinangwa chekutanga chehurongwa hwako.Kana iwe uri kuyedza kuenderana kusiyana nemajenareta dhizaini uye kuisirwa kunogona kuve kwakaoma uye iwe unofanirwa kuyeuka mabatiro einjini yekumisikidza, dhizaini yejenareta, uye dhizaini yedhizaini, kungotaura zvishoma.

Unogona kushandura 60 Hz jenareta kuita 50 Hz?
Kazhinji, majenareta mazhinji ekutengesa anogona kushandurwa kubva pa60 Hz kuenda pa50 Hz.Mutemo mukuru wechigunwe ndeye 60 Hz michina inomhanya pa1800 Rpm uye 50 Hz jenareta inomhanya pa1500 Rpm.Nemajenareta mazhinji achichinja frequency inongoda kudzikisira iyo rpm's injini.Mune zvimwe zviitiko, zvikamu zvinogona kuchinjwa kana zvimwe zvigadziriso kuitwa.Michina mikuru kana michina yakatogadzikwa pazasi Rpm yakasiyana uye inofanirwa kugara ichiongororwa pane imwe nyaya nenyaya.Isu tinosarudza kuita kuti matekiniki edu ane ruzivo atarise pane yega jenareta zvakadzama kuitira kuti vaone zvinogoneka uye izvo zvese zvinozodiwa.

Ndinoziva sei saizi yeJenareta yandinoda?
Kuwana jenareta inokwanisa kubata zvese zvaunoda kugadzirwa kwemagetsi ndechimwe chezvinhu zvakakosha pasarudzo yekutenga.Kunyangwe iwe unofarira simba rekutanga kana rekumira, kana jenareta yako nyowani isingakwanisi kuzadzisa zvaunoda saka haingaite chero chero chinhu chakanaka nekuti inogona kuisa kusagadzikana kusingaite payuniti.

Ndeapi saizi yeKVA inodiwa kupihwa nhamba inozivikanwa yemabhiza emagetsi angu emagetsi?
Muzhinji, wedzera huwandu hwese hwemabhiza emagetsi ako emagetsi ne 3.78.Saka kana uine 25 horsepower three phase motor, unozoda 25 x 3.78 = 94.50 KVA kuti ukwanise kutanga mota yako yemagetsi yakananga pamutsetse.
Ndinogona kushandura jenareta yangu yezvikamu zvitatu kuita chikamu chimwe chete?
