Kev xaim daim ntawv ntawm Fais Fab Tam Sim No Transformer
Dec 30, 2021| 1. Nws yog daim ntawv thaiv ntawm ib lub zog tam sim no Transformer.
Nws tsuas tuaj yeem cuam tshuam qhov xwm txheej ntawm ib theem tam sim no, uas tsim nyog rau qhov xwm txheej uas ib-theem tam sim no lossis peb-theem load tshuav yuav tsum tau ntsuas, thiab peb-theem tuaj yeem paub los ntawm kev ntsuas ib theem. Feem ntau ntawm lawv txuas nrog ammeters.
2. Peb-theem ua tiav lub hnub qub txuas thiab daim ntawv txuas delta.
Peb-theem Fais Fab Tam Sim No Transformer tuaj yeem ua raws sijhawm thiab raug nkag siab txog cov kev hloov pauv ntawm peb-theem load, thiab feem ntau yog siv rau hauv cov khoom siv hluav taws xob sib txawv ntawm kev tiv thaiv kab hluav taws xob. Tsuas yog siv peb-theem ua tiav lub hnub qub kev sib txuas, uas tuaj yeem siv rau tam sim no sau ntawm hluav taws xob ntsuas hluav taws xob hauv qhov nruab nrab taw tes ncaj qha hauv av. Txoj kev peb-theem peb-relay thaiv tsis tuaj yeem tsuas yog cuam tshuam ntau hom kev cuam tshuam luv luv, tab sis kuj muaj kev cuam tshuam ib-theem grounding luv circuits, yog li no txoj kev thaiv yog siv los ua interphase luv Circuit Court tiv thaiv thiab ib-theem grounding luv Circuit Court tiv thaiv hauv qhov nruab nrab point ncaj qha grounded system.
3. Ob-theem hnub qub tsis tiav daim ntawv txuas.
Nws yog feem ntau siv hauv kev ua haujlwm tiag tiag. Nws txuag hluav taws xob tam sim no Transformer thiab siv qhov sib xyaw tam sim no ntawm A thiab C los ua ib qho inverted B-theem tam sim no. Ob-theem ob-theem relay kev sib txuas hom tuaj yeem cuam tshuam qhov luv luv ntawm cov theem, tab sis tsis tuaj yeem cuam tshuam tag nrho ib-theem grounding luv Circuit Court, yog li nws tsis tuaj yeem siv rau kev tiv thaiv ib-theem grounding. Txoj kev thaiv kab no yog siv rau theem-rau-theem luv-circuit tiv thaiv nyob rau hauv nruab nrab point ungrounded system los yog arc suppression coil grounded system.
4. Ob-theem sib txawv tam sim no daim ntawv thaiv.
Nws kuj tsuas yog siv nyob rau hauv peb-theem peb-xaim circuits, qhov nruab nrab point tsis grounded, thiab tsis muaj nruab nrab hlau. Qhov kom zoo dua ntawm cov xaim no yog tias nws tsis tsuas yog txuag hluav taws xob tam sim no Transformer, tab sis kuj tuaj yeem siv cov relay los cuam tshuam ntau yam ntawm peb-theem circuits Phase-rau-theem short-circuit txhaum, uas yog, peb-theem dhau-tam sim no. kev tiv thaiv yog ua tiav nrog qhov tsawg kawg nkaus relay, txuag peev. Tab sis thaum daim ntawv txhaum yog txawv, nws rhiab heev yog txawv. Txoj kev xaim no feem ntau yog siv rau theem-rau-theem luv-circuit tiv thaiv hauv kev faib tawm ntawm 10kV thiab hauv qab no. Vim qhov tsis tshua muaj kev tiv thaiv zoo li no, nws tsis tshua muaj siv nyob rau niaj hnub no.
