1. Cov ntsiab lus tseem ceeb ntawm kev tiv thaiv relay Lub ntsiab lus tseem ceeb yog tias thaum lub cuab yeej tiv thaiv txav mus, tsuas yog lub luag haujlwm raug tshem tawm ntawm lub zog hluav taws xob, txhawm rau txo qhov kev ua haujlwm ntawm lub zog tsis ua haujlwm, thiaj li ua kom muaj kev nyab xeeb ntawm kev ua haujlwm tsis zoo. -fault ib feem ntawm qhov system. Kev ua haujlwm ceev txhais tau hais tias cov khoom siv tiv thaiv relay yuav tsum tau txiav lub txim txhaum sai li sai tau. Nyob rau hauv txoj kev no, qhov kev puas tsuaj ntawm cov khoom siv tsis raug tuaj yeem raug txo, tus neeg siv lub sijhawm ua haujlwm ntawm qhov tsis tshua muaj hluav taws xob tuaj yeem raug txo, thiab kev ruaj ntseg ntawm lub zog hluav taws xob tuaj yeem txhim kho. Lub peev xwm ntawm cov cuab yeej tiv thaiv rhiab heev los teb rau qhov tsis ua haujlwm lossis kev ua haujlwm tsis zoo hauv nws qhov kev tiv thaiv yog hu ua rhiab heev (rhiab heev). rhiab heev yog feem ntau ntsuas los ntawm rhiab heev coefficient. Nws yog txiav txim siab nyob rau hauv qhov nqi ntawm kev ntsuas lub ntsiab ntawm cov cuab yeej tiv thaiv, raws li kev ua haujlwm tsis zoo tshaj plaws, hom kev ua txhaum, qhov taw tes nyob rau hauv kev tiv thaiv ntau yam los xyuas, thiab ua tau raws li cov qauv tsim. Reliability Reliability yog hais txog qhov tseeb hais tias nyob rau hauv cov cuab yeej tiv thaiv, cov cuab yeej tiv thaiv yuav tsum ua kom ntseeg tau thaum qhov txhaum nws yuav tsum tshwm sim (piv txwv li, tsis muaj kev tsis lees paub).
2. Cov khoom siv tiv thaiv relay hauv kev ua haujlwm yuav tsum raug tshuaj xyuas raws li cov khoom hauv qab no: kev tshuaj xyuas cov khoom siv hluav taws xob thiab hluav taws xob cov yam ntxwv ntawm cov relay; kev ntsuas ntawm rwb thaiv tsev tsis kam ntawm theem nrab Circuit Court; kev ntsuam xyuas hluav taws xob theem nrab; thiab tag nrho kev ua haujlwm kev sim ntawm cov cuab yeej tiv thaiv.
3. Cov txheej txheem ua haujlwm rau kev tiv thaiv relay thiab calibration. Kev ntsuas kev tiv thaiv relay yuav tsum muaj ob txoj haujlwm, ib qho kev saib xyuas thiab ib qho haujlwm. Lub relay tiv thaiv calibration ua hauj lwm yuav tsum xyuas qhov tseeb ntawm qhov ntsuas ntsuas ua ntej ua qhov kev xeem. Qhov nruab nrab voltage txee Circuit Court breaker yuav tsum nyob rau hauv txoj hauj lwm xeem.
Cov ntsiab lus ntawm kev txheeb xyuas raws sij hawm ntawm kev tiv thaiv relay
1.Abstract: Relay tiv thaiv ntaus ntawv periodic calibration system Tshooj ntawm relay kev tiv thaiv thiab kev ruaj ntseg tsis siv neeg ntaus ntawv (hu ua "relay tiv thaiv ntaus ntawv") kev soj ntsuam ua hauj lwm yog lub technical txhais tau tias thiab cov kev ntsuas zoo los xyuas kom meej qhov tseeb ntawm relay tiv thaiv.
2. Cov ntsiab lus thiab lub voj voog ntawm kev tshuaj xyuas ib ntus Kev tshuaj xyuas tsis tu ncua yuav tsum tau ua raws li lub voj voog uas tau teev tseg hauv tus qauv no, cov haujlwm thiab cov ntsiab lus ntawm cov txheej txheem ua haujlwm cov lus qhia tau pom zoo los ntawm cov neeg muaj peev xwm ntawm txhua qib. Lub formulation ntawm lub sij hawm soj ntsuam lub voj voog txoj kev npaj yuav tsum ua tib zoo xav txog cov theem voltage thiab kev ua hauj lwm ntawm cov khoom nyob rau hauv nws cov kev tswj, thiab ua raws li lub voj voog thiab qhov project xav tau los ntawm tus qauv no.
3. Txhawm rau tiv thaiv cov khoom siv tiv thaiv relay ua kom ntseeg tau, cov khoom siv tiv thaiv relay thiab cov khoom siv hluav taws xob thib ob feem ntau yuav tsum tau kuaj xyuas lossis txheeb xyuas tsis tu ncua. Kev kuaj xyuas dav dav thiab kuaj xyuas yog ib xyoos. Kev tiv thaiv relay thiab theem nrab Circuit Court Nyob rau hauv cov ntaub ntawv ntawm lub hwj chim tsis ua hauj lwm, xyuas thiab xyuas cov hluav taws xob Cheebtsam thiab lwm yam Circuit Court. Feem ntau yuav tsum ua cov ntsiab lus hauv qab no:, relay mus rau lub tshuab tsis muaj qhov sib txawv
4. Txhawm rau kom ntseeg tau tias cov khoom siv tiv thaiv relay tuaj yeem ua tau zoo nyob rau hauv cov ntaub ntawv ntawm qhov tsis ua hauj lwm ntawm lub zog, cov khoom siv tiv thaiv relay thiab cov khoom siv hluav taws xob thib ob hauv kev ua haujlwm yuav tsum tau kuaj xyuas tsis tu ncua. Feem ntau, cov khoom siv tiv thaiv relay ntawm 10 kV fais fab tuag yuav tsum tau kuaj ib zaug txhua ob xyoos;
5. Pab pawg tiv thaiv relay yuav tsum tau nruab nrog yam tsawg kawg ntawm cov cuab yeej thiab cov cuab yeej hauv qab no: DL / T 955-200 pointer voltage, ammeter, digital voltage, ammeter, clamp ammeter, theem meter, millisecond meter, choj; 500V, 1000V thiab 2500V Metameter; nco oscilloscope; siab zaus oscillator thiab zaus ntsuas qhov yuav tsum tau rau cov cab kuj channel kuaj, uas tsis yog-inductive kuj, sib txawv attenuator, thiab lwm yam .;
6. Relay tiv thaiv kev tshuaj xyuas thiab kev tswj xyuas qhov system. Kev tshuaj xyuas thiab kev tshuaj xyuas tsis tu ncua yog qhov lav kom txhim kho qhov zoo ntawm kev tiv thaiv thiab kev txheeb xyuas, thiab tso rau pem hauv ntej cov kev cai meej rau cov khoom siv tshiab thiab kev tiv thaiv kev ua haujlwm los ntawm kev soj ntsuam mus rau qhov kev tshuaj xyuas tshwj xeeb. Cov txheej txheem pov thawj yuav tsum xa mus rau Kev Tshawb Fawb Cov Cai ntawm Kev Tiv Thaiv Relay thiab Fais Fab Kev Nyab Xeeb Kev Nyab Xeeb Tsis Siv Neeg Ntaus" thiab cov txheej txheem tshuaj xyuas tshwj xeeb.
