Kuj hu ua tooj liab busbars lossis tooj liab busbars, lawv yog ua los ntawm tooj liab.

 Lawv lub luag haujlwm tseem ceeb yog nqa tam sim no hauv Circuit Court thiab txuas ntau yam khoom siv hluav taws xob.

 Xav txog tej yam, tsis muaj tooj liab busbars, tam sim no yuav ya ncig aimlessly, thiab cov khoom siv hluav taws xob yuav tsis ua haujlwm zoo.

 Copper busbars tiag tiag ci hauv cov khoom siv hluav taws xob, tshwj xeeb tshaj yog nyob rau hauv cov khoom siv hluav taws xob ua tiav.

 Txawm hais tias nyob rau hauv cov khoom lag luam loj lossis hluav taws xob hauv tsev, tooj liab busbars ua lub luag haujlwm tseem ceeb.

 Lawv zoo li "txoj kev loj" hauv Circuit Court, tso cai rau tam sim no ntws zoo thiab tsis muaj kev cuam tshuam.

 Yog vim li cas tooj liab busbars siv es tsis txhob tooj liab rods nyob rau hauv qis -voltage switchgear yog hais tias, nyob rau hauv tib tus ntoo khaub lig-sectional cheeb tsam thiab saum npoo kub, lub peev xwm nqa tam sim no ntawm ib lub kaum sab xis tooj liab busbar yog ntau dua li ntawm tus pas nrig tooj liab.

 Thib ob, rau 50 Hz AC, daim tawv nqaij qhov tob tob ntawm tooj liab yog kwv yees li 9.3 hli, yog li txoj kab uas hla ntawm tus pas nrig tooj liab yuav tsum tsis pub tshaj 20 hli, yog li txwv lub busbar lub peev xwm nqa tam sim no.

 Hauv kev siv tswv yim, tooj liab conduits feem ntau yog siv los ua busbars hauv switchgear, es tsis yog tooj liab rods.

 Tsawg-voltage switchgear muaj tsawg voltage tab sis siab lub ntsiab busbar tam sim no, yog li qhov yuav tsum tau rau hluav taws xob clearance tsis siab, tab sis kub nce tswj yog qhov tseem ceeb tshaj rau nruab nrab - thiab siab -voltage switchgear.

 Qhov kub nce ntawm lub ntsiab busbar yog qhov tseem ceeb tshwj xeeb. Yog li ntawd, tooj liab busbars feem ntau yog siv nyob rau hauv qis -voltage switchgear, es tsis yog tooj liab rods.
