4, relay tiv thaiv thiab tu cov txheej txheem.4 Yog tsis muaj loosening lossis cuav vuam ntawm vuam txoj hauj lwm ntawm cov relay lead. Kev ntxuav cov cuab yeej siv. Txhua lub relay yuav tsum ua qhov ntsuas qhov ntsuas qhov ntsuas thiab ntsuas qhov ntsuas hluav taws xob. Cov kev sib cuag dynamic thiab zoo li qub ntawm txhua qhov kev sib txuas sib txuas yuav tsum tsis muaj paj tawg thiab deformation tshwm sim, thiab qhov sib txuas sib txuas yuav tsum ua tau raws li qhov yuav tsum tau ua ntawm cov kev qhia tshwj xeeb.
5, kev tiv thaiv relay thiab cov cuab yeej tsis siv neeg ntawm qhov chaw soj ntsuam cov txheej txheem.12 tam sim no kev tiv thaiv kev sib txawv (kev tiv thaiv qhov sib txawv ntawm lub tshuab hluav taws xob thiab lub tshuab hluav taws xob) tau txais cov txheeb ze polarity thiab qhov sib txawv ntawm txhua pab pawg ntawm lub voj tam sim no hauv kev tiv thaiv lub voj. Txawm hais tias kev xaim ntawm txhua pab pawg ntawm cov transformers tam sim no muaj tseeb thiab seb cov kab hluav taws xob sab hauv puas ntseeg tau.
Kev txheeb xyuas tom qab kev tiv thaiv kev sib tsoo relay belongs rau ib qho
1. Tib cov ntaub ntawv yog input ntau zaus, thiab ces ob batch ntawm cov ntaub ntawv yog muab piv los ntawm lub system. Txoj kev pov thawj no belongs rau ().
2. Ib lub ntsiab lus xaiv. Kev txheeb xyuas tom qab kev tiv thaiv kev sib tsoo relay belongs rau (). Part A yog check. B Tshawb pom hauv kev ua haujlwm. C Ntxiv calibration. Tshawb xyuas cov lus teb.
3. Kev soj ntsuam ntawm 25 relay tiv thaiv kev sib tsoo: Case 1: Hauv 110kV substation, thaum tus neeg teb xov tooj hloov kho qhov kev tiv thaiv tus nqi ntawm lub ntsiab transformer, xoom kab sib tshooj overvoltage tiv thaiv ntawm lub ntsiab transformer yuam kev tag nrho txiav peb sab. hloov ntawm lub ntsiab transformer. Kev tsom xam: tus neeg teb xov tooj tsis tau ua tib zoo saib xyuas cov txheej txheem hauv cov txheej txheem ntawm kev hloov kho tus nqi ruaj khov nyob rau theem tom qab ntawm kev saib xyuas, thiab ua yuam kev hloov qhov kev txiav txim xoom overvoltage tsau tus nqi rau 0V.------Case 2: Hauv 35kV substation, nyob rau hauv tus txheej txheem ntawm rov pib dua lub hwj chim kis tau tus mob tom qab lub xyoo kev tiv thaiv kev soj ntsuam thiab pre-test, nws tau ua nyob rau hauv lub zos nyob rau hauv lub high voltage chamber hloov txee vim qhov ua txhaum ntawm kev saib xyuas, thiab kev tiv thaiv kev tiv thaiv ntawm lub ntsiab transformer. poob siab nyob rau hauv tag nrho cov chaw nres tsheb. Kev tsom xam: 10kV kab ntawm kab hauv av tsis raug tshem tawm, nrog rau hauv av xaim kaw kev sib tsoo. Thaum "kev ua haujlwm / kev saib xyuas" ntawm lub iav hloov pauv hloov mus rau txoj haujlwm txij nkawm, kev tiv thaiv raug txiav tawm hauv lub voj thib ob. Txawm hais tias txoj kab kev ua txhaum raug tiv thaiv kom raug, qhov kev tawm mus tsis tuaj yeem mus, ua rau muaj kev tiv thaiv kev tiv thaiv ntawm lub ntsiab transformer mus txawv tebchaws.-----
