Relay tiv thaiv testernyob rau hauv ultra-high voltage fais fab tuaj yeem pab ntau tus neeg ua haujlwm fais fab ua ntau yam kev ntsuas hluav taws xob yooj yim dua.
Kev tiv thaiv relay yog qhov tseem ceeb heev rau kev ua haujlwm nyab xeeb thiab txhim khu kev qha ntawm cov khoom siv hluav taws xob thiab cov chaw nres tsheb. Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tsum tau ua tib zoo saib xyuas cov khoom siv relay hauv lub zog hluav taws xob kom ntseeg tau tias kev tiv thaiv kev ua haujlwm ntawm cov khoom siv tiv thaiv relay tuaj yeem siv tag nrho.
1, Lub luag haujlwm ntawm kev kuaj xyuas nyob
Kev txheeb xyuas cov khoom nyob hauv yog ib txoj haujlwm tsim nyog hauv kev tsim cov tshuab hluav taws xob. Tsuas yog los ntawm kev ua pov thawj ntawm kev thauj khoom tuaj yeem peb txiav txim siab seb qhov kev sib kis tau ua tiav thiab cov khoom siv fais fab tshiab muab tso rau hauv kev ua haujlwm li cas. Nyob rau hauv cov txheej txheem ntawm kev kuaj xyuas, kev tswj cov khoom siv relay kom ntseeg tau tias nws txhim khu kev qha thiab kev nyab xeeb yog qhov yuav tsum tau ua ua ntej kom ntseeg tau tias cov cuab yeej tseem ceeb hauv kev tsim hluav taws xob tuaj yeem muab tso rau hauv kev siv, thiab nws kuj yog ib txoj hauv kev tseem ceeb los xyuas qhov kev ua haujlwm zoo ntawm cov khoom siv thib ob. . Tsis tas li ntawd, thaum lub sij hawm tsim kho ntawm lub hwj chim infrastructure, load verification hauj lwm yuav tsum tau nqa tawm. Tsuas yog los ntawm kev txheeb xyuas cov khoom nyob tau tuaj yeem siv txoj hauv kev xaim thiab kev tiv thaiv cov txheej txheem tsim hluav taws xob hauv lub zog hluav taws xob tuaj yeem raug kuaj xyuas kom zoo, ua kom yooj yim rau kev txheeb xyuas raws sijhawm ntawm txoj kev xaim tsis raug thiab txhim kho kev tiv thaiv cov cuab yeej tsim qauv.
2, Cov kauj ruam rau kev kuaj xyuas cov khoom siv tiv thaiv relay
1) Load pov thawj ntawm busbar sib txawv tiv thaiv
Lub busbars ntawm fais fab nroj tsuag thiab substations yog cov cuab yeej tseem ceeb hauv lub zog hluav taws xob. Yog hais tias qhov kev ua txhaum ntawm busbar tsis tuaj yeem txiav tawm sai sai, nws yuav ua rau muaj kev sib tsoo kom nthuav dav, cuam tshuam rau kev ua haujlwm ruaj khov ntawm lub zog hluav taws xob, thiab ua rau lub zog tawg. Yog li ntawd, kev tiv thaiv busbar sib txawv yuav tsum tau muab tso rau hauv kev ua haujlwm ib txwm. Tab sis thaum lub tshuab hluav taws xob tshiab raug teeb tsa, lub tsheb npav sib txawv tiv thaiv yuav tsum raug kaw ua ntej them tus nqi hluav taws xob. Tom qab nqa lub load, tam sim no polarity ntawm kev tiv thaiv Circuit Court yuav tsum raug ntsuas kom raug ua ntej muab nws ntxiv. Yog li ntawd, tam sim no polarity ntawm busbar sib txawv tiv thaiv Circuit Court yuav tsum raug ua ntej ntxiv nws.
2) Load pov thawj ntawm lub ntsiab transformer sib txawv tiv thaiv
Longitudinal sib txawv tiv thaiv yog txuas cov tam sim no transformers ntawm txhua sab ntawm transformer siv txoj kev sib txawv kev twb kev txuas. Thaum lub transformer nyob rau hauv ib txwm thiab sab nraud luv luv Circuit Court, cov sum ntawm cov thawj tam sim no ntws nyob rau hauv thiab tawm ntawm txhua sab yog xoom, thiab qhov sib txawv relay tsis ua hauj lwm; Thaum muaj kev txhaum sab hauv, qhov sib npaug ntawm qhov luv-circuit tam sim no muab los ntawm txhua sab ntws mus rau hauv qhov sib txawv relay, thiab qhov sib txawv relay ua rau txiav tawm qhov txhaum.
3) Kev tiv thaiv kab kev tiv thaiv nrog kev kuaj xyuas
Txoj kab kev tiv thaiv muaj xws li kev tiv thaiv kev tiv thaiv overcurrent, xoom ib ntus kev tiv thaiv kev tiv thaiv overcurrent, kev tiv thaiv kev deb, kev tiv thaiv theem siab sib txawv, kev tiv thaiv ntau zaus, kev tiv thaiv kev tiv thaiv ntau zaus, kev tiv thaiv xoom kab, thiab lwm yam. rau kev ua haujlwm zoo ntawm lub cuab yeej. Txawm li cas los xij, thaum txhim kho cov xaim, qhov tseeb ntawm cov xaim yog qhov nyuaj rau lav, thiab nws yooj yim los txuas cov xov hlau tsis raug. Yog li ntawd, kev kuaj xyuas kev thauj khoom yuav tsum tau ua los xyuas kom meej qhov raug ntawm cov xaim.
Hauv kev ntsuam xyuas ntawm kev tiv thaiv relay thiab cov khoom siv tsis siv neeg, feem ntau ntawm cov kev ua tsis raug ntawm kev tiv thaiv relay thiab cov khoom siv tsis siv neeg yog tshwm sim los ntawm kev tiv thaiv kev taw qhia, kev tiv thaiv polarity txuas los ntawm txoj kev sib txawv ntawm kev sib txuas, los yog kev teeb tsa tsis raug. Yog li, lub hom phiaj ntawm kev ua cov ntaub ntawv pov thawj ntawm cov khoom siv tiv thaiv relay tshiab yog los xyuas kom meej tias txoj kab kev tiv thaiv raug txuas mus rau tam sim no (voltage) theem thiab polarity; Xyuas kom meej tias tus txheeb ze polarity kev sib raug zoo, kev hloov pauv, thiab kev teeb tsa ntawm txhua pab pawg ntawm circuits txuas nrog qhov sib txawv tiv thaiv Circuit Court yog raug; Xyuas kom meej tias qhov tam sim no (voltage) theem ib ntus txuas nrog kev tiv thaiv uas tsim los ntawm cov txheej txheem lim dej kom raug. Mastering cov txheej txheem ntawm kev kuaj xyuas qhov tseeb ntawm qhov ua tiav thiab kev ua haujlwm ntawm cov cuab yeej tshiab lossis cov phiaj xwm loj xa mus thiab hloov pauv tsis yog tsuas yog cuam tshuam rau kev nyab xeeb ntawm cov cuab yeej siv thawj zaug hauv kev xa hluav taws xob thiab kev hloov pauv cov haujlwm, tab sis kuj ua kom zoo ntawm cov khoom siv thib ob thiab kev teeb tsa. tsis txhob tso cov kev phom sij zais cia rau kev ua haujlwm nyab xeeb ntawm daim phiaj hluav taws xob.
