Kev sib raug zoo ntawm Cov Peev Xwm tawg thiab Rated Voltage: Interdependence
Cov lus hauv qab no qhia meej qhov kev sib raug zoo tseem ceeb no:
| Tswv yim | Txhais | Kev sib raug zoo rau kev tawg muaj peev xwm |
|---|---|---|
| Rated voltage (Ue) | Qhov kev ua haujlwm tsis tu ncua ib txwm ua haujlwm voltage uas lub Circuit Court breaker tsim, xws li 12kV, 24kV, 40.5kV. | Lub Foundation: Lub peev xwm tawg yuav tsum tau txhais thiab sim ntawm qhov ntsuas qhov tshwj xeeb no. |
| Lub peev xwm tawg (Icu / Ics) | Qhov siab tshaj yav tom ntej luv luv -circuit tam sim no (RMS tus nqi) lub breaker tuaj yeem cuam tshuam kev nyab xeeb ntawm nws qhov ntsuas hluav taws xob, qhia hauv kA (kiloamperes), piv txwv li, 25kA, 31.5kA. | Qhov Kev Ua Tau Zoo: Cov nqi no yuav tsum sib npaug los yog ntau dua li qhov siab tshaj plaws ntawm qhov kev cia siab luv luv -circuit tam sim no ntawm qhov chaw teeb tsa. |
Cov ntsiab lus tseem ceeb cuam tshuam nruab nrab ntawm lub peev xwm tawg thiab ntsuas hluav taws xob
Higher Voltage nce kev cuam tshuam nyuaj:
Rau tib lub luv luv-circuit tam sim no, qhov hluav taws xob ntau dua ua rau lub zog hluav taws xob ntev dua thiab xav tau kev rwb thaiv tsev ntau dua, ua rau muaj kev cuam tshuam ntau dua.
Breaking Capacity tau txheeb xyuas ntawm Rated Voltage:
Lub cim tawg muaj peev xwm (piv txwv li, 31.5kA) yog siv tau tshwj xeeb ntawm qhov ntsuas hluav taws xob (piv txwv li, 40.5kV).
Kev sib piv hauv kev siv tswv yim:
Breaker's Rated Voltage Ntau dua los yog sib npaug rau qhov System Operating Voltage.
Breaker's Breaking Capacity Ntau dua lossis sib npaug rau Qhov Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Tawm -Circuit Current ntawm qhov chaw teeb tsa.
Cov lus qhia tshwj xeeb rau cov teb no
Kev nkag siab txog qhov kev sib raug zoo no yuav ua rau koj muaj kev tshaj lij thaum txhawb nqa cov neeg siv hluav taws xob tauj dua tshiab (PV, Cua, Zog Cia):
| Daim ntawv thov Scenario | Qib voltage | Rhuav Txoj Kev Xav Tau | Koj Qhov Kev Sib Txuas Lus Pom Zoo |
|---|---|---|---|
| PV / Cua Farm Collector Kab | 35kV (40.5kV) | 25kA, 31.5kA | Ua kom pom tseeb cov khoom lag luam muaj kev ntseeg siab ntawm qhov system voltage, ntsib daim phiaj -sab luv- qhov yuav tsum tau muaj peev xwm ntawm Circuit Court. |
| BESS PCS (Power Conversion System) Daim phiaj kev sib txuas | 10 kV, 35 kV | Kev xav tau siab (piv txwv li, 31.5kA +) | Qhia txog qhov muaj peev xwm cuam tshuam sai los tiv thaiv cov roj teeb kim. |
| Diesel Generator Teeb Tso zis | 10.5 kV, 13.8 kV | Nyob ntawm GenSet Peev Xwm (piv txwv li, 50kA +) | Hais txog kev muaj peev xwm tawg nyob rau hauv cov xwm txheej ntawm qhov qis qis tab sis tsis tshua muaj siab luv -circuit tam sim no, uas yog qhov tseem ceeb rau kev tiv thaiv lub tshuab hluav taws xob. |
Covtawg peev xwmntawm Circuit Court breaker yog intrinsically txuas rau nwsntsuas voltage.
Ua ke, lawv txiav txim siab qhov txhaum siab tshaj plaws tam sim no lub breaker tuaj yeem cuam tshuam kev nyab xeeb.
Hauv cov ntsiab lus: qhov ntsuas hluav taws xob txhais tau hais tias "theem" uas nws ua haujlwm, thiab lub peev xwm tawg yog nws "kev ua haujlwm txwv" ntawm theem ntawd.
CovKev tawg muaj peev xwmyog lub Circuit Court breaker "qhov kawg lub zog" nyob rau theem ntawm nwsntsuas voltage.
Kev pom zoo cov khoom uas phim qhov project qhov system voltage thiab xam luv luv -circuit tam sim no yog tus nqi tseem ceeb ntawm tus kws tshaj lij.
Khoom Description
ZW32-24 sab nraum lub tshuab nqus tsev ncej-mounted Circuit Court breaker (tom qab no hu ua Circuit Court breaker) yog kev tswj thiab kev tiv thaiv cov cuab yeej siv hauv 24kV, 50Hz peb-theem AC nruab nrab-voltage tis network. Nws feem ntau yog siv rau kev hloov thiab cuam tshuam cov khoom thauj tam sim no, overload tam sim no, thiab luv-circuit tam sim no hauv cov kab xa hluav taws xob.
