High ceg delta, tseem hu ua wild-leg, stinger ceg, bastard ceg lossis siab ceg yog ib hom kev pabcuam hluav taws xob txuas rau peb theem hluav taws xob teeb tsaNws yog siv Thaum ob leeg ib leeg thiab peb theem fais fab xav tau los ntawm peb theem transformer.
txhais ceg siab yog dab tsi?
Nyob rau hauv qee txoj kev, cov kev pabcuam siab delta muab qhov zoo tshaj plaws ntawm ob lub ntiaj teb: kab-rau-kab hluav taws xob uas siab dua li ib txwm 208 V uas feem ntau cov kev pabcuam peb theem muaj, thiab line-rau-nruab nrab voltage (ntawm ob theem) txaus rau kev sib txuas cov khoom siv thiab teeb pom kev zoo
Yam twg yog ceg siab?
Lub siab-ceg lossis theem nrog qhov siab dua qhov ntsuas qhov nruab nrab tau ib txwm raug xaiv " Phase B". Kev hloov pauv rau xyoo 2008 NEC tam sim no tso cai rau cov ceg siab ntawm plaub-xaim peb-theem delta kev pabcuam raug sau npe tias "C" theem tsis yog theem "B ".
Dab tsi voltage muaj ceg siab?
Cov ceg siab voltage magnitude yog kwv yees li 208 voltsnrog lub kaum sab xis ntawm qhov tsis zoo 30 degrees thaum siv xoom degrees rau A Phase voltage (VAB) yog siv.
Koj paub koj txhais ceg siab npaum li cas?
Nyob rau 4-xaim, delta-txuas, 3-theem system, qhov nruab nrab ntawm ib theem winding ntawm theem nrab yog grounded (ib ceg siab), lub conductor nrog 208V rau hauv av yuav tsum tau ua kom ntev thiab cim tas mus li los ntawm ib qho kev ua tiav txiv kab ntxwv hauv cov xim lossis lwm yam txhais tau tias [110.15].
