800 kVA thiab 6 kV Roj-Filled Transformers: Parameter Matching Guide

Core Matching Parameter 1: Voltage Ratio thiab Kais Changer Alignment

Voltage compatibility yog lub hauv paus ntawm parameter txuam. Tus qauv voltage piv yog 6 kV thawj rau 0.4 kV theem nrab, sib piv cov cuab yeej siv khoom tus qauv 400 V tawm tswv yim. Ob qho kev hloov pauv yuav tsum muaj qhov sib npaug sib npaug, feem ntau ntxiv lossis rho tawm 5 feem pua ​​​​lossis ntxiv lossis rho tawm 2 los ntawm 2.5 feem pua, tso cai rau kev hloov pauv voltage ib txhij los them rau cov kab sib chaws hloov pauv. Cov pab pawg sib txuas yuav tsum ua kom zoo ib yam, nrog Dyn11 raws li tus qauv, ua kom muaj kev sib haum xeeb ntawm theem thiab tiv thaiv cov circulating tam sim no uas ua rau overheating. Ua ntej kev sib txuas, txheeb xyuas qhov tso zis hluav taws xob thiab coj mus rhaub txoj haujlwm ntawm 6 kV transformer thiab paub meej tias 800 kVA chav tsev qhov kev ntsuam xyuas thawj zaug thiab kais ntau qhov sib npaug, tom qab ntawd ntsuas theem theem nrog rau theem ntsuas.

Core Matching Parameter 2: Luv -Circuit Impedance Consistency

Luv- Circuit Court impedance cuam tshuam ncaj qha rau kev ua haujlwm tam sim no. Qhov pom zoo impedance ntau yog 6 mus rau 8 feem pua ​​​​rau ob chav nyob, nrog qhov sib txawv siab tshaj plaws ntawm 1 feem pua. Cov impedance tsis sib haum ua rau qhov tsis sib xws tam sim no: piv txwv li, 6 kV transformer ntawm 6 feem pua ​​​​ua ke nrog 800 kVA chav tsev ntawm 9 feem pua ​​​​ yuam kom 6 kV chav tsev nqa 60 feem pua ​​​​ntawm qhov txhaum tam sim no, ua rau muaj kev pheej hmoo luv luv - Circuit Court tsis ua haujlwm. Lub 800 kVA chav tsev impedance yuav tsum tau calibrated tiv thaiv 6 kV transformer lub peev xwm, yog li 6 kV chav tsev ntawm 1000 kVA los yog ntau dua khub zoo tshaj plaws nrog rau 800 kVA chav tsev 6 mus rau 7 feem pua ​​impedance.

Core Matching Parameter 3: Txias System Synergy

Ob chav nyob cia siab rau cov roj txias, thiab lawv cov tshuab cua txias yuav tsum tau sib tw kom tsis txhob muaj cua sov ntawm qhov siab. ONAN cua txias suits lub teeb-rau- nruab nrab loads; OFAF yuam kom txias yog yuav tsum tau rau tag nrho 800 kVA nruam load nyob rau hauv hnyav industrial siv; thiab OFWF dej txias yog ib qho kev xaiv rau siab - qhov kub thiab txias ib puag ncig xws li thaj chaw kub thiab txias los yog chav fais fab. Ob chav nyob yuav tsum siv tib qhov nruab nrab insulating kom yooj yim txij nkawm, thiab cua txias kiv cua thiab twj tso kua mis voltage thiab tswj logic yuav tsum synchronized.

Core Matching Parameter 4: Load Capacity thiab Scalability

Lub peev xwm ntawm 6 kV transformer yuav tsum yog 1.2 mus rau 1.5 npaug ntawm 800 kVA chav tsev qhov peev xwm, khaws cov npoo rau qhov siab tshaj plaws thiab kev nthuav dav yav tom ntej. Yog tias ib qho 6 kV transformer pub ntau 800 kVA units, tag nrho 800 kVA muaj peev xwm yuav tsum tsis pub tshaj 80 feem pua ​​​​ntawm 6 kV chav tsev qhov ntsuas. Ob lub tshuab hloov pauv yuav tsum tswj 120 feem pua ​​​​ntawm qhov muaj peev xwm mus txog ib teev los txhawb luv luv - lub sij hawm xav tau siab xws li lub Hoobkas pib.

Core Matching Parameter 5: Kev tiv thaiv kev sib koom ua ke

Cov khoom siv tiv thaiv overload yuav tsum tau ntsuas rau txhua chav ntsuas qhov muaj peev xwm nrog synchronized thresholds, xws li lub tswb ntawm 110 feem pua ​​​​ntawm load thiab kaw ntawm 120 feem pua. Circuit Court breakers thiab fuses yuav tsum muaj qhov cuam tshuam cuam tshuam, feem ntau 25 txog 31.5 kA rau 6 kV systems. Lub siab nyem li qub tau teeb tsa rau 0.05 txog 0.1 MPa thiab roj qib saib xyuas yuav tsum ua kom muaj lub tswb sib koom ua ke, thiab ob qho tib si hloov pauv yuav tsum txuas mus rau lub hauv paus tiv thaiv relay nrog cov kev sib txuas lus sib txuas rau kev tshawb nrhiav kev txhaum ib txhij.

Cov lus nug nquag
