Shigar da Motors - Haša "star" da "Delta"

Uku-lokaci motor - lantarki inji aka tsara aiki a uku-lokaci alternating halin yanzu. Irin wannan engine aka hada da wani stator da kuma na'ura mai juyi. A stator yana da uku windings canja da mutum ɗari da ashirin digiri. Lokacin da uku-lokaci ƙarfin lantarki a kewaye da windings a zura sandunan samar da Magnetic fluxes auku na'ura mai juyi juyawa. Electric Motors ne synchronous da asynchronous. Uku-lokaci shigar da Motors suna yadu amfani da masana'antu da kuma rayuwar yau da kullum. Irin wannan Motors ne guda gudun, wanda idan da mota Winding an haɗa a kan wani "star" ko "alwatika" da Multi-gudun. A karshe raka'a switchable a cikin irin wannan yanayin, akwai wani mulki daga connection zuwa wani kewaye.

Uku lokaci Motors rabu da Tuddan dangane makirci. Akwai biyu wayoyi zane - Haša "star" da "Delta". Connection na mota windings na da irin "star" ne fili na ƙyallen maƙalawa a motor windings a daya aya (sifili aya): samu ƙarin fil - sifili. The free iyakar an haɗa ka da bulan na cibiyar sadarwa na lantarki 380 V. External connection ne reminiscent na uku-nuna star. A hoto ya nuna da wadannan makirci: Connect wani "star" da "Delta". Haxawa da mota windings na "alwatika" wakiltar irin serial dangane da windings: a farko karshen alaka zuwa farkon na biyu Tuddan karshen na biyu - farkon na uku, da kuma kawo karshen farkon uku na farko. A Tuddan dangane nodes na uku-lokaci ƙarfin lantarki yana amfani. Wannan dangane ne ba sifili fitarwa windings. Outwardly, yake kama da alwatika.

Fili a "star" da "alwatika" ne daidai da na kowa, su ba su da mahimmin bambance-bambance. Don haɗa da windings na da irin "Star" (lokacin da engine ne a rated gudun), da layin ƙarfin lantarki dole ne mafi girma daga a dangane da irin "alwatika". Saboda haka, cikin halaye na uku-lokaci motor nuna maras muhimmanci irin ƙarfin lantarki kamar haka: 220/380 ko 127/220 V. Idan zama dole, gama da mota zuwa 380 cibiyar sadarwa a wani maras muhimmanci irin ƙarfin lantarki na 220/380 V windings bukatar da za a haɗa da wani "star" type, da kuma kimanta motor ƙarfin lantarki ne 380/660 V ( "alwatika" type).

Ya kamata a lura da cewa shi ne sau da yawa amfani hade a wata "star" da "Delta". Wannan ne yake aikata domin mafi m fara da mota. A farkon-amfani dangane da irin "star," sa'an nan ta amfani da musamman canji da aka sauya zuwa "alwatika", game da shi, rage inrush halin yanzu. Irin wannan makircinsu suna shawarar for fara manyan da wutar lantarki bukata a manyan farawa halin yanzu. Yana da muhimmanci a tuna cewa yayin da inrush halin yanzu ya wuce da maras muhimmanci sau bakwai.

Akwai sauran haduwa a lokacin da aka haɗa Motors, misali da fili "star" da "alwatika" iya maye gurbinsu da biyu, sau uku, "star", kazalika da sauran embodiments na connection. Irin wannan hanyoyin da ake amfani da Multi-rate (biyu, hudu, da sauransu. D.) Motors.
