Kev teeb tsa ntawm tam sim no transformers (CT) nyob rau hauv substations nws txawv nyob ntawm seb qhov voltage, qhov system layout thiab functionality yuav tsum tau. Cov nram qab no yog cov configurations thiab lawv cov yam ntxwv:
1. Kev teeb tsa los ntawm lub hom phiaj
(1) Kev ntsuas transformer
Configuration qhov chaw: Feem ntau ntsia ntawm qhov hluav taws xob ntawm lub tsheb npav lossis lub voj, siv los sau cov ntaub ntawv tam sim no.
Muaj nuj nqi: Muab cov cim qhia tseeb tam sim no rau cov cuab yeej ntsuas hluav taws xob thiab cov cuab yeej saib xyuas.
(2) Kev tiv thaiv transformer
Configuration qhov chaw: Feem ntau nyob rau ntawm ob sab ntawm lub Circuit Court breaker los pab txhawb cov cuab yeej tiv thaiv kom pom qhov txhaum tam sim no.
Muaj nuj nqi: Muab cov teeb liab raug tam sim no rau cov khoom siv tiv thaiv relay rau kev kuaj pom thiab kev cais tawm.
2. Kev faib tawm los ntawm cov khoom siv hluav taws xob teeb tsa qhov chaw
(1) Bus side configuration
Qhov chaw: Lub transformer yog ntsia rau ntawm high voltage sab los yog tsawg voltage sab ntawm lub ntsiab transformer thiab lub tsheb npav.
Qhov zoo: Nws tuaj yeem saib xyuas cov xwm txheej ntawm lub ntsiab transformer thiab tsheb npav, uas yooj yim rau kev ntsuas thiab kev tiv thaiv.
(2) Circuit Court breaker sab configuration
Qhov chaw: Nruab rau ntawm ob sab ntawm lub Circuit Court breaker los xyuas qhov tam sim no ntawm cov kab lossis cov khoom siv.
Qhov zoo: Txhim kho qhov rhiab heev thiab kev ntseeg tau ntawm kev tiv thaiv kab.
(3) Configuration ntawm ib sab ntawm seem hloov
Qhov chaw: Nruab ntawm qhov chaw tsheb npav txuas lossis ib sab ntawm txoj hlua khi.
Qhov zoo: Yooj yim rau kev tiv thaiv cov tsheb npav thiab kev sib npaug ntawm qhov system.
3. Kev teeb tsa rau lub hom phiaj tshwj xeeb
(1) Zero-sequence tam sim no transformer
Muaj nuj nqi: Siv los xyuas peb-theem tam sim no qhov tsis txaus ntseeg kom ua tiav kev tiv thaiv hauv av.
Txoj kev teeb tsa: ntsia ntawm qhov nruab nrab ntawm qhov hloov pauv lossis ntawm qhov hluav taws xob cable.
(2) Sib txawv tiv thaiv transformer
Muaj nuj nqi: Muab kev tiv thaiv sib txawv rau cov cheeb tsam tshwj xeeb thiab cais cov kev ua txhaum sai sai.
Configuration method: Nruab rau ntawm high-voltage, nruab nrab-voltage, thiab tsawg-voltage sab ntawm lub ntsiab transformer los tsim ib tug tiv thaiv ntau yam.
(3) Theem-splitting tam sim no transformer
Muaj nuj nqi: Muaj kev ywj pheej txheeb xyuas txhua theem tam sim no, tsim nyog rau cov xwm txheej uas yuav tsum tau saib xyuas txhua theem load.
Configuration method: Npaj nyob rau hauv high-voltage system los yog tseem ceeb load Circuit Court.
4. Kev rov ua dua thiab kev teeb tsa ua pab pawg
Rov qab configuration
Txhawm rau txhim kho kev ntseeg tau, qhov tseem ceeb tam sim no transformers feem ntau yog teeb tsa redundantly. Piv txwv li:
Ob lub transformers yog configured tib lub sij hawm rau kev ntsuas thiab kev tiv thaiv raws.
Configure backup transformers los daws cov cuab yeej tsis ua hauj lwm.
Pab pawg configuration
Pab pawg los ntawm kev ua haujlwm, xws li pab pawg tiv thaiv thiab pab pawg ntsuas, kom tsis txhob muaj ib qho txhaum rau tag nrho cov kab ke.
5. Kev teeb tsa hauv cov khoom siv hluav taws xob ua ke
Hauv cov khoom siv hluav taws xob sib xyaw ua ke (GIS), tam sim no transformers feem ntau yog ua ke nrog cov disconnectors thiab Circuit Court breakers kom txo qhov chaw hauv pem teb thaum optimizing layout thiab tu.
