Tau 380V thiab 220V nruab nrab ntawm cov xaim hluav taws xob sib txawv tuaj yeem hloov pauv tau
Cov cai tswj kev nyab xeeb rau kev teeb tsa hluav taws xob tsawg; Txhawm rau tiv thaiv cov khoom siv hluav taws xob los ntawm ob lub zog sib txawv los ntawm kev ua kom muaj hluav taws xob thiab kev sib tsoo, cov neeg siv uas siv ob lub zog hluav taws xob (xws li cov khoom siv hluav taws xob sab nraud thiab sab hauv) rau kev faib hluav taws xob yuav tsum teeb tsa plaub tus ncej dual pov hloov pauv hloov hluav taws xob.
Ob qhov sib txawv transformer low-voltage fais fab mov tshuab (piv txwv li A transformer low-voltage fais fab mov system thiab B transformer low-voltage fais fab mov system). Piav tias yog vim li cas txoj kab xoom tsis tuaj yeem siv tau.
Qhov qis-voltage winding coils ntawm transformers yog tag nrho txuas nrog Y-puab, thiab cov hlau tsis zoo ua haujlwm yog cov hlau hu ua N xaim uas txuas los ntawm qhov nruab nrab ntawm qhov chaw O ntawm lub hnub qub zoo li Y-point. Nws lub luag haujlwm tseem ceeb yog muab 220V voltage rau theem kab L1 → N, L2 → N, thiab L3 → N, ntsig txog, siv los ntawm kev thauj khoom ib zaug.
Cias muab, thaum ib qho kev thauj khoom ib zaug ua haujlwm, cov kab theem thiab cov kab nruab nrab yuav tsum tsim lub voj kom ua haujlwm zoo.
Tej zaum qee tus neeg txawj ntse thiab siab tawv tau hais tias kuv ib zaug sim cov kab theem ntawm ib lub tshuab hloov pauv nrog xoom kab ntawm lwm lub tshuab hloov pauv, siv lub teeb 220V 💡 Nws nyuam qhuav teeb. Ntawm no kuv yuav qhia rau koj tias nws yog qhov ua tau tiag tiag los teeb lub teeb pom kev zoo, uas yog ib qho kev ua haujlwm uas tsim los ntawm kev tiv thaiv hauv av thiab rov ua dua thiab kev tiv thaiv hauv av PE ntawm lwm lub transformer.
Rau cov transformers ntsia nyob rau hauv ntau qhov chaw, cov kev tiv thaiv grounding nteg nruab nrab ntawm lawv yog haum rau hauv zos tej yam kev mob thiab txuas nrog rau hauv av. Qhov kev tiv thaiv hauv av tshwj xeeb yog cuam tshuam los ntawm kev ncua deb thiab av av. Txawm hais tias tus nqi hauv av ntawm txhua qhov khoom siv hauv av yog nyob rau hauv ib txwm muaj R Tsawg dua lossis sib npaug rau 4 Ω, yuav muaj 4 Ω +4 Ω + lub ntiaj teb kev ua txhaum R ntawm lawv. Cov txiaj ntsig zoo li no tsis paub meej thiab tsis haum rau kev ua haujlwm tam sim no, thiab qhov hluav taws xob nyob rau hauv qhov kev ua haujlwm ib txwm muaj ntawm cov khoom thauj tsis tuaj yeem lav.
Txhawm rau muab nws bluntly, txoj hauv kev no tshwj xeeb tsis muaj kev nyab xeeb. Cov cai tswj kev nyab xeeb rau cov khoom siv hluav taws xob yog qhov tsis txaus ntseeg kiag li. Rau cov khoom siv hluav taws xob uas muaj cov khoom tiv thaiv tam sim no tau teeb tsa hauv cov khoom siv hluav taws xob tsawg, lawv yuav tawm mus tam sim thiab nres lub zog hluav taws xob.
