Hanyar farawa ta matsin lamba ta cikin triangle (Y-HanHanHanyarfarawa):

A triangle sauke ƙarfin lantarki farawa yana nufin a lokacin da injin ya fara, sa stator juyawa a cikin star siffar (Y), don rage farawa ƙarfin lantarki, iyakance farawa halin yanzu; Bayan injin ya fara, sa'an nan kuma canza madaidaicin madaidaicin madaidaicin madaidaicin madaidaicin madaidaicin madaidaicin madaidaicin madaidaicin madaidaicin madaidaicin madaidaicin madaidaicin madaidaicin madaidaicin madaidaicin madaidaicin madaidaicin Kawai motar asynchronous da ke zagaye da stator a cikin triangle (A) a lokacin aiki na yau da kullun za a iya amfani da wannan hanyar farawa ta ƙarancin matsin lamba. Lokacin da injin ya fara, haɗi a cikin siffar, ƙara a kan kowane mataki stator juyawa a kan farawa halin yanzu ne 1/3 na kai tsaye ta amfani da triangular junction, farawa da kuma kawai 1/30 na triangular junction kai tsaye farawa

Yana aiki ne kawai don farawa a ƙarƙashin haske ko blank load. Amfanin S-siffar triangle daya cutarwa matsin lamba farawa shine kayan aiki ne mai sauki, low farashi, don haka samun mafi fadi aikace-aikace. Rashin amfani shi ne kawai don injin lantarki da aka yi amfani da shi a lokacin aiki na yau da kullun a matsayin A, da daidaitaccen matsin lamba, wani lokacin ba zai iya saduwa da buƙatun farawa ba.

A. Inline-triangular farawa ya kamata a lura da:

1, da ƙarfin lantarki na mota ne 380V don fara tare da indoor-triangle.

2, manufa shuka gefen mota layi kula da ba gajeren haɗi, U1, V1, W1 kula da W2, U2, V2.

3, idan kariya ta dakatar da lokaci a lokacin zafi mai yawa (don Allah bincika ikon injin).

4, lokaci relay na canji lokaci daidaita daidai da injin aiki gudun.
