Siab - ceg delta (tseem hu ua wild- ceg , lus ceg , tug ceg , siab - ceg , txiv kab ntxwv- ceg , los yog liab- ceg delta) yog ib hom hluav taws xob kev pabcuam kev sib txuas rau peb-theem hluav taws xob lub zog installation. Lub hwj chim peb-theem txuas nrog hauv delta configuration, thiab qhov chaw nruab nrab ntawm ib theem yog grounded.
Hais txog qhov no, lub hom phiaj ntawm ib ceg siab yog dab tsi?
Tus thawj lub hom phiaj ntawm "siab ceg "Kev pab cuam yog muab lub cev muaj zog thiab teeb pom kev zoo los ntawm ib qho kev pabcuam. Raws li tau tshaj tawm saum toj no, lub cev muaj zog yog ruam. Yog tias theem rau theem voltage yog nyob rau hauv lub cev muaj zog siab, lawv yuav khiav zoo. TSIS TXAUS SIAB 120 VOLT, TSIS TXAUS SIAB, LOADS RAU LUB HIGH LEG.
Kuj Paub, txhais ceg hauv hluav taws xob yog dab tsi? Kub yog tej yam conductor (hlau los yog lwm yam) txuas nrog ib tug hluav taws xob system uas muaj hluav taws xob muaj peev xwm txheeb ze rau hluav taws xob av los yog nruab nrab. Leg zoo li hauv kub ceg ” hais txog ib qho ntawm ntau yam kub conductors hauv ib qho hluav taws xob qhov system.
Kev sib raug zoo, theem twg yog tus ceg siab?
Cov Lus Qhia. Cov siab - ceg los yog theem nrog rau qhov siab dua voltage raws li ntsuas rau nruab nrab tau ib txwm raug xaiv " Theem B». Kev hloov pauv rau 2008 NEC tam sim no tso cai rau cov siab ceg ntawm plaub-xaim peb- theem delta kev pabcuam yuav tsum tau sau npe ua "C" theem es tsis txhob "B" theem.
415v txhais li cas?
Peb-theem hluav taws xob yog ib hom kev sib hloov tam sim no hluav taws xob tsim hluav taws xob, kev sib kis, thiab kev faib tawm. Nws yog ib hom polyphase system thiab yog txoj kev siv feem ntau siv los ntawm cov kab hluav taws xob thoob ntiaj teb los hloov lub zog. Nws yog kuj tseem siv tau rau lub zog loj motors thiab lwm yam hnyav loads.

Lub ntsiab txhais ntawm lo lus hluav taws xob hluav taws xob yog dab tsi?
Npe. Cov hluav taws xob hluav taws xob txhais tau tias yog hluav taws xob hluav taws xob uas tso cai rau kev ua haujlwm kom tiav. Ib qho piv txwv ntawm lub zog hluav taws xob yog lub zog los ntawm lub qhov hluav taws xob ntsaws. YourDictionary txhais thiab siv piv txwv
Dab tsi yog qhov txawv ntawm kev txuag hluav taws xob thiab lub hauv paus ntsiab lus ntawm kev txuag hluav taws xob?
Lub caloric txoj kev xav tau khaws cia tias cov cua sov tsis tuaj yeem tsim los yog rhuav tshem, qhov kev txuag ntawm lub zog ua rau lub hauv paus ntsiab lus tsis sib xws uas cov cua sov thiab cov tshuab ua haujlwm sib hloov tau
Dab tsi yog hom hluav taws xob hluav taws xob sib txawv?
Qhov sib txawv ntawm cov hluav taws xob hluav taws xob muaj nyob hauv cov hluav taws xob hluav taws xob muaj xws li xov tooj cua tsis muaj zog, microwaves, infrared tsis, pom lub teeb, ultraviolet hluav taws xob, X-rays, thiab gamma rays. Ib feem ntawm cov electromagnetic spectrum uas peb tuaj yeem pom yog qhov pom lub teeb spectrum
Dab tsi yog cov yam ntxwv ua siab hloov hluav taws xob hloov hluav taws xob LET muaj thaum piv nrog LET hluav taws xob tsawg?
Dab tsi yog cov yam ntxwv ua kom muaj hluav taws xob hloov hluav taws xob siab (LET) hluav taws xob muaj thaum piv nrog cov hluav taws xob qis-LET? Cov huab hwm coj ntau ntxiv, txo qhov nkag mus. (Vim lawv cov nqi hluav taws xob thiab cov khoom loj heev, lawv ua rau ntau ionizations hauv cov ntaub so ntswg, sai sai poob lub zog
Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms?
Tus nqi zoo attracts tus nqi tsis zoo thiab ua rau lwm tus nqi zoo. Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms? Cov nqi hluav taws xob yog cov cuab yeej ntawm tag nrho cov atoms
