Hom Kev Sib Tw Circuit Court

Cov Ntsiab Lus Tseem Ceeb ntawm Circuit Court

(1) ntsuas ntsuas hluav taws xob (ue)

Qhov ntsuas cov ntsuas hluav taws xob yog cov nominal voltage ntawm uas cov Circuit Court breaker tuaj yeem ua haujlwm txuas ntxiv raws li kev siv thiab kev ua tau zoo.

Hauv Suav teb, rau cov qib voltage ntawm 220kv thiab hauv qab no, qib siab ua haujlwm siab tshaj yog 1.15 npaug ntawm cov kab hluav taws xob ntsuas; Rau 330kv thiab saum toj no, nws yog 1.1 npaug ntawm qhov ntsuas hluav taws xob. Kev sib txuas nrog lub rooj sib tsoo yuav tsum ceev rwb thaiv tsev ntawm lub kaw lus siab ua haujlwm siab tshaj plaws thiab ua haujlwm raws li cov cai tshwj xeeb.

(2) rated tam sim no (hauv)

Qhov ntsuas nyob tam sim no yog qhov tam sim no uas lub tsev mus ncig ua si tuaj yeem nqa mus txuas ntxiv ntawm qhov kub ntawm 40 ° C lossis qis dua. Rau cov kev sib txuas sib txuas nrog cov kev sib txuas nrog cov chaw taug kev kho tau, nws yog qhov siab tshaj plaws tam sim no lub chaw mus ncig tuaj yeem nqa tsis tu ncua.

Thaum siv cov huab cua kub siab tshaj 40 ° C tab sis tsis yog tshaj li 60 ° C, lub thauj khoom tuaj yeem txo qis kev ua haujlwm tas mus li.

(3) Kev mus ncig ua si dhau mus ncig ua si tam sim no chaw (IR)

Thaum qhov tam sim no tshaj lub dawm uas teev cov chaw tam sim no (IR), cov kev sib tw Circuit Court tom qab ncua sijhawm. Nws kuj tseem yog sawv cev rau qhov siab tshaj plaws tam sim no cov kev ua txhaum Circuit Court tuaj yeem tiv thaiv tsis muaj kev sib tw. Tus nqi no yuav tsum muaj ntau dua qhov siab tshaj plaws (IB) tab sis tsawg dua qhov kev tso cai tam sim no tau tso cai los ntawm Circuit Court (IZ).

Cov chav ua si thermal no feem ntau hloov kho tsis pub dhau 0.7-1.0in, thaum cov khoom siv hluav taws xob muaj cov khoom siv hluav taws xob ntau dua, feem ntau 0.4-1.0in. Rau cov tsis hloov kho cov tsev sib tw uas tau hloov pauv, ir = hauv.

(4) Lub sijhawm luv luv ntawm cov tsheb ciav hlau tam sim no chaw (IM)

Luv-Circuit Court kev mus ncig ua ke (instantaneous lossis ncua sij hawm ncua) dawm cov Circuit Court breaker sai sai thaum siab ua txhaum cov khoom tshwm sim. Lub dawm uas IM.

(5) Cov ntsuas ntsuas luv luv-sijhawm tiv thaiv tam sim no (ICW)

Qhov no yog tus nqi tam sim no tus nqi hluav taws xob tuaj yeem nqa tau lub sijhawm tshwj xeeb uas tsis muaj kev ua rau tus neeg coj ua vim muaj kev kub ntxhov.

(6) Muaj peev xwm tawg

Lub peev xwm rhuav tshem yog lub Circuit Court breaker lub peev xwm los xyuam xim cuam tshuam kev txhaum lossis tsis hais txog nws cov ntaus nqi tam sim no. Cov lus qhia tam sim no muaj 36ka, 50ka, thiab lwm yam nws feem ntau muab faib ua qhov kawg ntawm qhov muaj peev xwm luv (ICU).

Cov ntsiab cai rau kev xaiv Circuit Court

Firstly, xaiv qhov Circuit Court breaker hom thiab ncej raws li nws daim ntawv thov. Xaiv cov rated tam sim no raws li qhov siab tshaj plaws ua haujlwm tam sim no. Xaiv hom kev mus txawv tebchaws, cov khoom siv, thiab kev tshwj xeeb raws li xav tau. Cov kev txwv tshwj xeeb muaj:

1. Lub Circuit Court breaker's rated operating voltage yuav tsum ≥ Txoj kab kev siv hluav taws xob.
2. Qhov ntsuas kev ntsuas luv luv-cercuit reming muaj peev xwm yuav tsum ≥ lub ntsuas cov thauj khoom tam sim no ntawm kab.
3. Qhov ntsuas kev ntsuas luv luv-Circuit Rhuav lub peev xwm yuav tsum tau ≥ qhov ntau tshaj plaws corrmuit Court tam sim no uas yuav tshwm sim hauv kab (feem ntau tau suav ua rms).
4. Ib-theem av ua txhaum tam sim no ntawm kab kawg yuav tsum yog ≥ 1.25 lub sij hawm lub instantaneous (lossis ncua sij hawm) ncig ua si ntawm Circuit Court breaker.
5. Lub undervoltage mus txawv tebchaws chav tsev's rated voltage yuav tsum sib npaug ntawm txoj kab kev ntsuas ntsuas.
6. Lub shunt travent chav tsev cov ntsuas hluav taws xob yuav tsum sib npaug ntawm cov tswj lub zog hluav taws xob.
7. Lub cev muaj zog tsav tshuab ntsuas cov ntsuas hluav taws xob yuav tsum sib npaug ntawm kev tswj lub zog hluav taws xob.
8. Rau kev teeb pom kev zoo li cas, qhov chaw mus txawv tebchaws tam sim no yog feem ntau rau lub sijhawm thauj khoom tam sim no.
9. Rau ib lub cev muaj zog tiv thaiv kab ke luv luv, qhov chaw nyob nrawm dua tam sim no yuav tsum yog 1.35 zaug (DW series) lossis 1.7 zaug (DZ series) lub cev muaj zog.
10. Rau ntau lub motors 'luv luv-Circuit Txwv, cov kev mus txawv tebchaws tam sim no yuav tsum yog 1.3 npaug ntawm lub cev muaj zog loj tshaj plaws ntxiv rau kev ua haujlwm tam sim no ntawm lwm lub zog.
11. Thaum siv raws li qhov qis-voltage sab lub ntsiab hloov rau cov kev xa khoom tam sim no yuav tsum tsis pub tshaj lub chaw ntsuas hluav taws xob tam sim no, thiab cov chaw tsheb ciav hlau tsis muaj peev xwm tshaj tawm tam sim no Cov kev tiv thaiv kev tiv thaiv dhau los tam sim no yuav tsum sib npaug ntawm cov kev hloov pauv ntawm cov ntsuas ntsuas.
12. Tom qab pib xaiv lub Circuit Court breaker hom thiab kev ntsuam xyuas, ua kom cov yam ntxwv tiv thaiv nrog cov hloov pauv thiab dej ntws mus los tiv thaiv kev sib tsoo thiab nthuav cov txhaum.

Circuit Court Breaker Xaiv

Hauv lub tshuab faib khoom, cov foob pob hluav taws tau faib rau ntawm lawv qhov kev tiv thaiv kev ua haujlwm rau hauv hom xaiv thiab tsis xaiv. Xaiv cov neeg hluav taws xob tsawg-voltage Circuit Court cov foob pob ua txhaum muab ob-theem thiab peb-theem kev tiv thaiv. Instantaneous thiab luv luv-lub sij hawm ncua kev coj ua luv luv-Circuit Court, thaum lub sijhawm ntev ncua kev tiv thaiv kev tiv thaiv ntau dua. Tsis yog-xaiv hluav taws xob cov tog neeg feem ntau ua los ntawm kev tiv thaiv luv luv, muab qee qhov kev tiv thaiv luv luv xwb, txawm hais tias qee tus muaj kev tiv thaiv ntev ntev. Hauv cov tshuab faib khoom, yog tias txoj kev nce qib txuas ntxiv yog qhov xaiv hauv nroog yog tsis xaiv, lub sijhawm luv luv mus rau qhov kev txiav txim siab lossis ncua sijhawm ua kom muaj kev xaiv.

Thaum siv cov hluav taws xob nrog cov kev sib cav sib ceg ntxiv, xav txog:

1. Txawm hais tias cov neeg siv hluav taws xob hauv qab yog xaiv lossis tsis xaiv, cov pa hluav taws xob ntau tshaj li 1.1 npaug
2. Yog tias tus neeg tsis muaj kev tiv thaiv kab mob hauv qab, tiv thaiv cov kab ke luv luv uas muaj kev tiv thaiv nrog kev tiv thaiv qis dua thaum ua haujlwm hauv qab no vim tias tsis muaj peev xwm ua kom muaj kev tiv thaiv qis. Cov Uppeream breaker lub sijhawm luv luv-ncua sij hawm dhau mus taug kev qhov chaw tam sim no yuav tsum tsis pub tsawg tshaj li 1.2 npaug ntawm cov dej ntws hauv nroog
3. Yog tias muaj cov breaker hauv qab kuj tseem xaiv, ua kom muaj kev xaiv los ntawm kev teeb tsa lub sijhawm luv luv 0.1 ncua sijhawm ntev dua li tus neeg poob qis lub sijhawm luv. Feem ntau, kom ntseeg tau tias nce ntawm ntws los ntawm ntws los ntawm cov neeg sib tw uas ntev dua qhov kev txiav txim siab ntev dua, thiab cov kev ua haujlwm nce qib qis dua li cov dej ntws hauv chav dej tam sim no, ua kom iop.1 ≥ 1.26op.2.

Cascading kev tiv thaiv ntawm Circuit Court cov tog

Hauv kev faib cov qauv kev tsim qauv, ua kom muaj kev xaiv kom muaj kev xaiv ntawm cov kev sib koom tes thiab cov tog hluav taws xob nrog txoj kev xaiv "kev xaiv, thiab rhiab heev."

Xaiv tau cuam tshuam nrog kev sib koom tes ntawm cov kev sib koom tes thiab cov dej ntws tawm ntawm cov khoom tiv thaiv thiab cov kab kev ua haujlwm.

Cov kev ua haujlwm tsim nyog ntawm cov dej ntws nce los thiab cov dej ntws los cais cov kev ua txhaum cai Cov Hom Kev Ua Haujlwm Tsis Raug Cai Ntawm Circuit Court
