Synchronous galimoto - ubwino ndi kuipa

Ambiri ntchito makina monga galimoto synchronous ndi analandira makampani ndi pamene pali magetsi wothamanga pa liwiro zonse. Mwachitsanzo, compressors ndi injini zamphamvu, mapampu actuators. Komanso, mota synchronous ndi mbali yofunika, ndi zipangizo zambiri zapakhomo, monga ndi maola.

Mfundo ntchito makina ndi wosavuta. Mogwirizana wa onsewo maginito ya armature opangidwa ndi alternating panopa minda ndi maginito pa mizati inductor kwaiye zonse panopa ndi maziko a mfundo ya ntchito chipangizo chotero monga synchronous galimoto magetsi. Childs, ndi inductor ili ozungulira, ndipo Nangula - ndi stator. injini zamphamvu ngati mizati ntchito electromagnets. Koma pali mtundu wa otsika mphamvu - mota synchronous ndi maginito okhazikika. Chachikulu kusiyana pakati synchronous ndi asynchronous makina - stator ndi ozungulira kamangidwe.

Kuti imathandizira galimoto ku mlingo oveteredwa liwiro zambiri ntchito mode asynchronous. Mu mode izi, inductor kumulowetsa lalifupi-circuited. Pambuyo injini amapita ku liwiro oveteredwa, ndi rectifier amapereka DC inductor. Only mwadzina liwiro synchronous galimoto akhoza ntchito paokha.

Chotero mota zambiri ubwino. Iye ndi dongosolo la udzakwaniritsidwa zovuta kuposa makina asynchronous, koma izi kuchepetsa ndi chiwerengero cha ubwino. Mmodzi mwa ubwino waukulu - mphamvu yake ntchito popanda kumwa mphamvu zotakasika kapena amadza. Choncho injini mphamvu Chinthu ndi wofanana ndi umodzi. Pansi pa zikhalidwe izi, ndi synchronous AC galimoto ndi oyeretsedwa yogwira katundu maukonde chigawo. A zotsatira mbali ndi kuchepetsa galimoto kukula (kwa galimoto kupatsidwa ulemu, ndi stator kumulowetsa kuchita masamu ndi achangu ndi zotakasika mafunde pa). Komabe, injini synchronous akhoza kupanga mphamvu yakuuka ndi zotakasika, kugwira ntchito mu mode overexcitation.

The galimoto synchronous zambiri saganizira kusinthasintha ndi voteji akutsikira mu maukonde. Monga magalimoto magetsi ndi kukana apamwamba kuti overloads. zotheka kuonjezera zimamuchulukira imapanga injini ndi kuwonjezeka malemeredwe panopa. Ubwino ndi makina synchronous ndi zonse wodzitcha rotational liwiro pa katundu aliyense (kupatula zimamuchulukira).

Mosakayikira, makina monga galimoto synchronous ali ndi zofooka zakenso. Iwo ali oyanjana ndi ndalama yapamwamba ndi ntchito yovuta. The vuto lalikulu ndi malemeredwe ya galimoto ndipo M'mawu ake oyamba mu synchronism. Panopa anapeza kufala thyristor exciters, omwe apamwamba dzuwa, koposa tizilombo toyambitsa matenda magetsi. Komabe, mtengo awo ndi apamwamba kwambiri. Ntchito thyristor lophimba angathetse mavuto ambiri: mulingo woyenera malemeredwe panopa lamulo, thandizani cosine Phi phindu zonse, ulamuliro voteji pa tayala, kulamulira stator mafunde ndi ozungulira mu mode mwadzidzidzi, ndipo ngati zimamuchulukira.
