Generator ntaus ntawv - DC tshuab

Alternator - qhov no hluav taws xob tshuab uas converts zog txhua yam ntawm lub prime Mover kev sib hloov mus rau hauv hluav taws xob DC zog. Tom qab ntawd, generator yuav xa cov hloov siab los ntseeg lub zog neeg. generator apparatus raws li nyob rau hauv electromagnetic induction txoj cai. Ib qho ntawm feem ntau cov hom ntawm cov khoom yog cov thiaj li hu ua synchronous generator. Qhov no hluav taws xob tshuab, kev khiav hauj lwm nyob rau hauv alternating tam sim no. Synchronism yog tiav vim lub xub ntiag ntawm ib tug tej yam muaj pes tsawg tus ntawm ncej officers. Yog li, rau ib tug muab zaus cov muab ceev yog qhov.

generator ntaus ntawv yog heev yooj yim. Nws lub ntsiab qhov chaw yog electromagnets uas tsim ib yam magnetic teb, thiab ib tug armature uas winding.

Thauj tog rau nkoj - yog ib tug ntawm cov yooj yim qhov chaw uas ua tau lub fais generator. Nws muaj ib tug cylindrical zoo. Mus thauj tog rau nkoj ntawm cais los xij ntawm stamped hluav taws xob steel, lub thickness ntawm cov uas yog tsawg tshaj li ib nrab ntawm ib millimeter. Nruab nrab ntawm lub los xij yog ib tug txheej ntawm lacquer los yog daim ntawv rwb thaiv tsev. Thaum assembling depressions uas nashtampovat circumferentially rau txhua daim ntawv yog compressed tsim grooves nyob rau hauv uas insulated conductors yog stacked armature winding.

Generator ntaus ntawv muab rau ib tug collector. Nws muaj ob peb tooj liab daim hlau uas soldered nyob rau hauv ib txhia qhov chaw mus rau lub armature winding. Lawv kuj insulated los ntawm kev sib cuag nrog txhua lwm yam. Lub collector yog nyob rau hauv lub generator nyob rau hauv kev txiav txim kom rectify qhov tam sim no thiab xu nws mus rau ib tug sab nraud network ntawm lub nyob khov kho txhuam. Lub collector yog tsau nyob rau hauv armature ncej.

Raws li hais saum toj no, cov generator ntaus ntawv yog tsis tau tsis tau cov kev siv ntawm electromagnetic induction txoj cai. Uas yog vim li cas cov hluav taws xob generator muaj nyob rau hauv nws cov electromagnets ntaus ntawv, uas muaj xws li ncej hlau cores. Lub cores yog rotated los ntawm bolts rau tus ncej generator ntawm cov cam khwb cia hlau. Nyob rau hauv me me lub tsheb tej zaum nws tshwm sim hais tias ib tug ncej yog molded ncaj nraim nrog cov tub ntxhais. Nyob rau hauv feem ntau qhov cores yog twv los ntawm daim ntawv hlau. Nyob rau hnav ib tug tub ntxhais kauj ua los ntawm ib tug coiled thereon tooj liab hlau. Hlau thiab insulated. Cob phum excitation tam sim no dhau los ntawm lub kauj, tug tsim magnetic flux. Rau nws zoo tis rau huab cua ncua cov txheej txheem nrog tug ua ke los ntawm steel los xij lugs.

Thauj tog rau nkoj, spinning nyob rau hauv ib tug sib nqus teb uas induces ib tug nce mus nce los nyob rau hauv cov kev taw qhia thiab magnitude ntawm lub electromotive quab yuam (EMF) nyob rau hauv lub windings ntawm lub armature conductors. Lawm soldered mus rau lub xaus ntawm ib tug tig thiab lwm muab tus txhuam nplhaib, txuas rau lawv mus rau lub lwm network yuav tau txais apparatus muaj ib tug AC generator, txij thaum nyob rau cov ntaub ntawv no kev sib hloov ntawm lub soldered kauj tsim ib tug sib nqus teb nce mus nce los nyob rau hauv zaus thiab tam sim no cov kev taw qhia.

Synchronous generators twb dav nyob rau hauv thauj, tshwj xeeb yog kev tsheb nqaj hlau. Feem ntau, lawv yog siv nyob rau hauv locomotives, nyob rau hauv lub tub yees seem.
