Cov kab hluav taws xob tswj tau tuaj nyob rau hauv ntau qhov ntsuas qhov ntsuas hluav taws xob, nrog 450 / 750V yog qhov kev ntsuas ntau tshaj plaws.
Hauv kev siv tswv yim, qhov ntsuas hluav taws xob no ua tau raws li qhov yuav tsum tau muaj ntawm cov tshuab feem ntau cuam tshuam nrog kev tswj hwm thiab teeb liab kis. Qhov ntsuas 450/750V qhia txog theem voltage ntawm 450V thiab kab hluav taws xob ntawm 750V. Kev tswj cov kab hluav taws xob nrog qhov ntsuas no tau siv dav hauv kev lag luam xws li kev lag luam automation, theem ob hauv cov tshuab hluav taws xob, thiab hluav taws xob tswj rau cov tsev kom xa cov kev tswj thiab ntsuas cov cim.
Txawm li cas los xij, cov kab hluav taws xob tswj tau muaj nrog rau lwm qhov ntsuas hluav taws xob tshwj xeeb tshaj li 450/750V. Piv txwv li, cov ntawv tshwj xeeb tuaj yeem siv cov kab hluav taws xob tswj hwm ntawm 0.6 / 1kV; cov no tuaj yeem tiv taus cov hluav taws xob ntau dua thiab tsim nyog rau cov xwm txheej nrog cov kev xav tau nruj dua lossis cov cheeb tsam electromagnetic complex. Hloov pauv, rau cov khoom siv me me - teev tswj lossis qis- cov tshuab hluav taws xob nrog cov kev xav tau qis dua, cov kev xaiv nrog cov ntsuas qis dua muaj nyob. Thaum kawg, qhov kev xaiv ntawm qhov ntsuas hluav taws xob rau lub cable tswj yog nyob ntawm qhov kev thov tshwj xeeb thiab cov khoom siv hluav taws xob.
