Kev xaiv ntawm DC Circuit Court breaker

Feem ntau hais lus, thaum xaiv DC Circuit Court breaker, cov ntsiab lus tseem ceeb yuav tsum tau xav txog yog cov yam ntxwv tseem ceeb xws li ntsuas ua haujlwm voltage, ntsuas tam sim no, tripping teeb tam sim no thiab voltage thiab tam sim no ntawm shunt thiab undervoltage mus txawv tebchaws.

l. Raws li qhov ib txwm muaj tam sim no ntawm DC Circuit Court, pib xaiv lub Circuit Court breaker ntawm cov lus qhia thiab cov qauv.

2. Raws li qhov ntsuas hluav taws xob ntawm DC fais fab mov, txoj hauv kev hauv av (Hom A, B, C) thiab suav luv luv - tus nqi hluav taws xob tam sim no, thaum kawg txiav txim siab tus naj npawb ntawm cov theem thiab txoj kev xaim ntawm lub voj voog. breaker. Txoj kev txiav txim tshwj xeeb yog raws li hauv qab no:

Rau hom A (tsis zoo hauv av) qhov system: Txiav txim seb tus naj npawb ntawm cov ncej hauv series rau tus ncej zoo raws li lub zog hluav taws xob thiab qhov ntsuas luv luv -circuit tam sim no uas yuav tsum tau tawg. Xav txog qhov kev sib cais ntawm cov rwb thaiv tsev ntawm cov ncej tsis zoo, ib tus ncej ntxiv yuav tsum tau txuas nrog tus ncej tsis zoo ntawm lub Circuit Court breaker.

Rau hom B (center point grounding) system: muab lub zog hluav taws xob sib txuas los ntawm ib qho -ib nrab kom tau txais qhov hluav taws xob siv rau qhov zoo thiab qhov tsis zoo, thiab siv qhov voltage thiab luv luv - tam sim no rau yuav tsum tau tawg los txiav txim qhov Circuit Court breaker uas nws tus ncej zoo thiab tsis zoo yuav tsum tau txuas nrog hauv series Number of poles.

Rau hom C (ob qho tib si zoo thiab tsis zoo ncej yog tsis grounded) system: txiav txim seb yuav tsum tau tus naj npawb ntawm Circuit Court breaker ncej raws li lub hwj chim mov voltage thiab luv luv -circuit tam sim no uas yuav tsum tau tawg. , tusyees faib tus naj npawb ntawm cov ncej tau txais nyob rau hauv qhov zoo thiab tsis zoo ncej raws li nyob rau hauv series.

3. Qhov ntsuas ua haujlwm voltage Ue thiab ntsuas tam sim no Ie ntawm DC Circuit Court breaker. Nws yuav tsum tsis txhob qis dua qhov kev ntsuas ua haujlwm voltage thiab ua haujlwm tam sim no lossis suav tam sim no ntawm cov kab thiab cov khoom siv feem. Qhov ntsuas hluav taws xob ua haujlwm ntawm lub tshuab hluav taws xob muaj feem cuam tshuam nrog kev tsim thiab tawg peev xwm thiab kev siv qeb. Cov khoom siv hluav taws xob tib yam tuaj yeem muaj ob peb qhov ntsuas ua haujlwm voltages thiab sib xyaw ua ke thiab rhuav tshem cov peev txheej thiab pab pawg.
