Asynchronous generator

Ntsib nrog cov kev xaiv ntawm cov generator, tsis muaj nrog koj yuav tuaj nyob xws li ib tug tshaj plaws li ib tug induction generator. Tsis yog txhua tus to taub nws tseem ceeb. Yog hais tias koj thov kom txhais rau dictionaries, muaj peb yuav nrhiav tau cov nram qab no txhais: asynchronous generator yog hu ua qhov hluav taws xob siv lub tshuab, uas ua hauj lwm raws li ib tug generator. Nws yog ib tug pab qhov twg los ntawm hluav taws xob tam sim no thiab tsis tshua muaj hwj chim braking ntaus ntawv. generator rotor yog tsav los ntawm ib tug tsav lub cev muaj zog. Cov kev taw qhia kev sib hloov ntawm coincides nrog lub magnetic teb, tab sis tshwm sim nyob rau hauv ib tug ceev npaum li cas. Thaum zawv zawg lub rotor tau nrhiav ib tug tsis zoo nqi tshwm rau hauv lub generator ncej braking torque thiab lub tshuab muab rau cov hluav taws xob network. Yuav kom koj khiav lag luam xws li ib tug generator yog yuav tsum tau hais tias tus network yog ib tug generator reactive lub hwj chim, uas yog haum rau synchronous tshuab.

Yog xav xaiv ib generator rau lub tsev thiab xyuas kom meej uninterrupted hluav taws xob hauv koj lub tsev, koj yuav tsum tau paub nrog nws tsis. Ua ntej ntawm tag nrho cov, koj yuav tsum nqa mus rau hauv tus account lub peev xwm ntawm tus generator thiab tag nrho cov load rau nws, yuav ua li cas muaj ntau yam pab kiag li lawm nws yuav tau muab hluav taws xob. Cov muaj xws li cov feem ntau tsim nyog cov khoom nyob rau hauv lub tsev: hluav taws xob, teeb pom kev zoo, hwj kais boiler. Tag nrho cov pab kiag li lawm tsis tas yuav tsum tau muaj nyob rau hauv lub network nyob rau tib lub sij hawm, tseem ceeb tshaj mas, mus rau lub generator hwj chim los muab lawv nrog txaus ua hauj lwm tsis tas. Thaum xaiv ib tug yuav tsum tau mus tsom rau nram qab no cov yam ntxwv: asynchronous los yog synchronous generator, ib tug diesel los yog roj av, lub hwj chim pab kiag li lawm thiab tus naj npawb ntawm theem.

generator hwj chim yuav xam raws li nram no: nws yog tsim nyog los loj cosφ, uas txhua kws yog muab faib los ntawm lub peev xwm, qhia nyob rau hauv nws cov kev yam ntxwv. Tsis tas li ntawd, lub hwj chim generator yuav xam.

Lub generators yog ob hom: ib-theem thiab peb-theem. Lawv meant rau txawv hom phiaj. Yog hais tias koj siv ib tug peb-theem generator, nws yog tsim nyog los muab ntawm cov peb theem tusyees loaded. Thaum siv ib zaug xwb-theem generator ntawm xws li ib tug teeb meem tsis tshwm sim. Generator uas sau rau roj av, ntau yooj yim rau siv nyob rau hauv lub caij ntuj no, nws muaj teeb meem-dawb lub lag luam yog sib npaug zos rau yim lub sij hawm. Rau hauv sib piv, lub diesel generator muaj ib tug ntev lub neej thiab yog tsim los rau ib tug ntev kev pab cuam lub neej.

Ua ntej koj xaiv synchronous los yog asynchronous generator, koj yuav tsum txiav txim siab dab tsi yog qhov possibilities ntawm lub generator los xyuas kom meej high-zoo ua hauj lwm nrog pab kiag li lawm uas haus reactive lub hwj chim, thiab yuav ua li cas nws tuam haujlwm txais high inrush tam sim no. Synchronous generator thiab muaj peev xwm ntawm generating active thiab reactive lub hwj chim thiab nws ua hluav taws xob ntau nraaj. Xws li ib tug generator yuav mas inrush currents tshaj ob mus rau peb lub sij hawm lub nominal. Nyob rau tib lub sij hawm, nws cov nqi yog heev siab heev.

Rau hauv sib piv, synchronous, asynchronous generator yog tsis zoo yoog mus rau pib tsaws ntxhee, tab sis yog resistant kom luv luv circuits thiab overloads. Nyob rau hauv asynchronous generator tso zis voltage yog tsawg raug rau non-linear distortions. Nws yog siv rau lub hwj chim incandescent teeb, qhov txos, irons, xov tooj cua, hluav taws xob tso cua sov, computers thiab hluav taws xob. Yog hais tias koj npaj yuav siv ib tug generator nrog reactive loads, ces yuav tsum tau mus muab hwj chim rau ob los yog peb lub sij hawm. Nws nqi qis tshaj hais tias ntawm lub synchronous generator.

Qhov zoo oscillator yam ntxwv xws li nws tsis tshua muaj klirfaktor, cim tias seb thaum tus nqi ntawm nws cov zis voltage dua harmonics. Qhov no tus nqi nws yog sib npaug zos rau ob feem pua. Yog li, lub induction lub cev muaj zog-generator muaj peev xwm ntawm ua tsuas pab tau zog. Rau asynchronous generator zoo xws li nws tsis muaj qhov chaw uas yog nkag mus rau sab nraud los uas yuav tsum tau hloov thiab kho. Vim li no, lub generator mus rau ib tug me me raws li kev kawm los hnav thiab yog tsim los rau lub lag luam nruam.

Yog hais tias koj xav tau ib tug asynchronous lub cev muaj zog, ib tug generator hauj lwm, nws yog haum rau lub hom phiaj no, lub collector electric tsav muaj ib tug mus tas magnet nyob rau hauv stator. Koj tsis txawm yuav tau ua tej yam loj alterations. Thaum lub cev muaj zog ncej rotates los ntawm nyob ze rau qhov nominal tus nqi ntawm lub zaus, lub DC voltage yuav tsum generated. Raws li ib tug asynchronous generator haum thiab Stepper motors, tab sis lawv yuav tsum tau tig nrog ib tug me me zaus.
