Yuav ua li cas txiav txim siab qhov voltage ntawm U-shaped tubular rhaub?
Yog tias U-hloov hluav taws xob tubular rhaub tsis muaj daim ntawv lo, nws nyuaj rau kev txiav txim siab qhov voltage. Qhov kev tawm tsam tsuas yog ntsuas nrog multimeter, thiab ntsuas qhov ntsuas tsis tau. Lub raj xa cua sov tsis tuaj yeem txuas nrog cov qhov hluav taws xob sib txawv ntawm yuav. Yog hais tias lub mas voltage ntawm cov yeeb nkab cua sov yog 220V, nws yuav tsum siv zog los ntawm 220V, tsis yog 380V, lossis nws yuav kub sai sai; yog tias qhov ntsuas hluav taws xob tsis zoo ntawm U-puab hluav taws xob tubular rhaub yog 380V, nws tuaj yeem siv los ntawm 380V lossis 220V, qhov qub yog qhov ntsuas lub zog ua haujlwm, tom kawg yog 1/3 ntawm kev ntsuas hluav taws xob ua haujlwm.
Yog lawm, cov khoom siv rwb thaiv tsev nruab nrab ntawm cov cua sov hlau yuav tsum raug txiav txim siab hauv kev ua haujlwm tiag tiag. Feem ntau, cov khoom siv insulating sau nrog magnesia sab hauv cov cua sov muaj qhov ua tau zoo rwb thaiv tsev, thiab qhov hluav taws xob ntau ntawm ntau pua volts yuav tsis cuam tshuam rau nws txhua lub sijhawm.
