Cob phum magnet lub cev muaj zog thiab nws daim ntawv thov

Cob phum magnet lub cev muaj zog - yog ib tug los kom txo qhov nyhav thiab qhov ntev ntawm qhov hluav taws xob siv lub tshuab, mus piv rau nws cov qauv, txhim kho kev ntseeg thiab kev tsis siv. Xws li ib tug lub cev muaj zog tso cai considerably rau kom efficiency (lub efficiency). Qhov loj muab faib rau nws tau txais raws li ib tug synchronous tshuab. Nyob rau hauv no apparatus, mus tas li hlau nplaum yog tsim thiab siv los mus tsim ib yam magnetic teb.

Tam sim no siv lub neej coj variant: tas mus li hlau nplaum nrog lub electromagnet, lub kauj uas ntws ib qhov hluav taws xob tam sim no. Qhov no ua ke excitation muaj ntau yam zoo nta: muab yuav tsum tau hloov li cas lawm voltage yam ntxwv thiab ceev thaum uas txo lub tsav tsheb hwj chim, txo qhov ntim ntawm lub magnetic system (thiab, thiaj li, tus nqi ntawm xws li ib tug ntaus ntawv, raws li ib tug ua ke tas mus li magnet lub cev muaj zog) raws li muab piv nrog rau cov classical electromagnetic excitation ntawm ib tug synchronous system tshuab.

Rau hnub tim, cov kev siv ntawm mus tas li cov hlau nplaum yog tau nyob rau hauv lub hwj chim ntawm tus dais no yog tsuas ib ob peb kilovolt-amperes. Tam sim no, txawm li cas los, tsim tas mus li hlau nplaum nrog zoo tuaj kawm, thiab siv tshuab los hwj chim maj tsub kom.

Synchronous lub cev muaj zog raws li ib tug mus tas magnet lub cev muaj zog yog siv raws li ib tug lub cev muaj zog los yog generator ncaj qha drives ib tug txawv lub hwj chim. Xws li tau pom daim ntawv thov thiab muab faib rau cov mines, smelting nroj tsuag, thermal fais fab nroj tsuag. Txij li thaum lub synchronous lub cev muaj zog ua hauj lwm nrog cov sib txawv reactive lub hwj chim, nws yog siv nyob rau hauv tub yees, cov twj thiab lwm yam mechanisms nrog ib tug tsis tu ncua ceev. Cov hluav taws xob lub cev muaj zog nrog tas cov hlau nplaum siv nyob rau hauv lub pab kiag li lawm thiab muaj hwj huam pab kiag li lawm, uas yuav tsum tau nruj thiab leej ceev constancy. Qhov no tsis siv neeg cov ntaubntawv povthawj siv seev, elektrochasy, software ntawm lwm yam uas, thiab tshaj. Thaum noj thiab substations yog tshwj xeeb synchronous generators uas tsim idling tsuas reactive lub hwj chim. Lub hwj chim no yog siv rau asynchronous motors thiab synchronous machines ntawm no hom yuav hu ua "compensators".

Cov kev khiav hauj lwm hauv paus ntsiab lus ntawm xws li ib tug tshuab raws li ib tug lub cev muaj zog nrog tas cov hlau nplaum, thiab nyob rau hauv particular, tus synchronous lub cev muaj zog raws li cov kev sis raug zoo ntawm cov sib nqus teb ntawm lub rotor (rooj noj ib feem) thiab ib tug stator (tsau ib feem).

Vim qhov nthuav thiab tseem tsis tau tag nrho to taub cov hlau nplaum zog thiab muaj feem ntau nyob invention raws li nyob rau hauv lawv. Piv txwv li, ib qho ntawm feem ntau cov tswv yim yog los tsim ib tug ntaus ntawv xws li ib tug perpetual tsab ntawv tsa suab tshuab tsis roj rau tas mus li hlau nplaum. Ntawm tus taw tes ntawm view ntawm niaj hnub science thiab physics perpetual tsab ntawv tsa suab tshuab yog tsis yooj yim sua (nws yuav tsum muaj lub efficiency yog ntau tshaj ib tug, thiab yog hais tias yuav tsis txaus ntseeg), tab sis lub inventors nyob rau hauv lub teb ntawm lwm lub zog tsis txhob poob vam cia rau lub creation thiab kev loj hlob ntawm xws li ib tug discovery.
