Ndi mphamvu ya magetsi chiyani?

Anthu ambiri, pamene akulankhula za chinthu chotero monga mphamvu za magetsi zikutanthauza mphamvu. Komabe, ngakhale mu njira sayansi sukulu adapatsidwa kuzindikira kuti mphamvu - izi ndi mfundo zosiyana ngakhale ofanana.

Lingaliro la "mphamvu" amatanthauza khalidwe la chochitika chinachake. N'zotheka kusonkhana mphamvu ndi chinthu. kanthu thupi angatchedwe mphamvu. ntchito wangwiro otchedwa monga anadutsa mphamvu ntchito njira. Akugwira ntchito mphamvu kwa nthawi yaitali, kodi kukhala wolingana ndi mphamvu. Choncho, mphamvu - ndi kuchuluka thupi, wofanana ndi chiŵerengero cha ntchito, anachita kwa nthawi zina mphamvu zina, nthawi ino.

Komabe, tiyenera kukumbukira kuti mphamvu umatchedwanso muyeso wa muyeso mphamvu. Choncho n'zotheka kuganizira mfundo imeneyi mawu angatchedwe ndi kusintha kwa mphamvu mu dongosolo ena (mphamvu mlingo kutembenuka).

Ngakhale mawu ndi matanthauzo anapatsidwa pamwamba ikukhudzana bwanji ndi wamkulu mphamvu mawotchi, izi zonse angapeze mfundo monga "mphamvu ya magetsi." The mankhwala a voteji panopa ndi amatchedwa mphamvu panopa. Popeza lingaliro ili zimatengera mofanana pa voteji ndipo panopa, tinganene kuti yomweyo mphamvu ya magetsi analandira pamene lalikulu panopa ndi voteji otsika ndi pa voltages mkulu ndi mafunde otsika. katundu maziko a mphamvu kufala pa maulendo ataliatali kudutsa zomera mphamvu, substations, tiransifoma (kulera ndi kutsitsa), switchgear ndi zina zamagetsi.

magetsi lagawidwa mitundu iwiri chachikulu: zotakasika ndi proactive. Yogwira mphamvu - khalidwe la kusintha magetsi ku mitundu ina ya mphamvu (kutentha, zoyenda, kuwala). magetsi amayezedwa Watts (W). Tsiku ndi tsiku, mphamvu imeneyi nthawi amayezedwa kilowatts, ndi ntchito zomera lalikulu mphamvu ndi mayunitsi zikuluzikulu - Megawatts.

Zotakasika mphamvu ya magetsi amadziwika katundu magetsi mu zipangizo zosiyanasiyana. Ndi wofanana ndi mankhwala a dontho voteji kudutsa pano opaleshoni ndi sine wa gawo kosangalatsa ngodya (gawo kusiyana) pakati panopa ndi voteji dontho. mphamvu zotakasika amayezedwa Volt-amperes zotakasika (var).

mphamvu yogwira zikhoza kugwirizana ndi mphamvu ya magetsi kudzera mwa mfundo monga "mphamvu Chinthu" - kusiyana kwa gawo panopa ndi voteji. Pakuti zipangizo zambiri banja cosine adzakhala wofanana ndi za 0,8. Zipangizo Kutentha nthawi zambiri makamaka anamuukitsa kwa mgwirizano.

Anayeza mphamvu ya magetsi ndi chipangizo wapadera - mphamvu mita. Chotero chipangizo ali windings awiri. Woyamba ndi waya wandiweyani chikugwirizana ndi ogula la mphamvu ya magetsi, ndipo detects kusintha ukulu panopa. The chachiwiri kumulowetsa imakhala ndi waya woonda ndi kulumikizana mu kufanana kuti akomere voteji. Mphamvu zomera zambiri ntchito chinthu choterocho monga "anaika mphamvu ya magetsi," yemwe ndi Uwerenge ndi ubongo oveteredwa onse makina magetsi a mtundu umodzi wokha kapena mtundu (mwachitsanzo, tiransifoma, magudumu, Motors).
