Lub luag hauj lwm ntawm xob laim tiv thaiv ntawm CRT qhuav hom Transformers
Txhim kho xob laim ntes tiv thaiv kom tsis txhob xob laim overvoltage. Rau kev tiv thaiv xob laim ntawm qhuav-hom transformers, seamless hlau oxide ntes tau teeb tsa los tiv thaiv overvoltage los tiv thaiv lub mains transformers los ntawm intruding rau hauv high-voltage thiab low-voltage kab intruding rau high-voltage xob laim thiab ua rau cov rwb thaiv tsev puas. Tus ntes yog siv los tiv thaiv cov tshuab ziab khaub ncaws qhuav. Ua ntej, yuav cov khoom tsim nyog los ntawm txoj hauv kev ib txwm, pib ua haujlwm tom qab kev sim nruj, thiab nruab thiab ua haujlwm tom qab ua tau raws li qhov yuav tsum tau ua. Qhov ob yog ua kom muaj kev tiv thaiv kev ntsuas ntawm cov cuab yeej siv hauv kev ua haujlwm tsis tu ncua, thiab pauv cov khoom tsis tsim nyog uas nws cov khoom xau tam sim no tshaj tus nqi siv hauv lub sijhawm. Rau kev sim siab tshaj 100 kVA, cov av tiv thaiv yuav tsum tsis pub dhau 4Ω. Kev faib khoom qhuav-hom transformer qis dua 100 kVA hais txog cov av tiv thaiv hauv 10Ω. Yog tias qhov ntsuas tus nqi tsis nyob hauv qhov kev teev tseg, txuas ntxiv cov xaim hauv av kom nce lub cev hauv av, thiab siv lub cev thiab tshuaj ntsuas kom ncav cuag tus nqi teev. Qhov kev tiv thaiv ntawm lub pob tw yog ntsuas ob zaug hauv lub Plaub Hlis thiab Lub Xya Hli txhua xyoo. Kev tiv thaiv hauv av tsis dhau tus qauv vim qhov poob ntawm qhov vuam taw tes thiab ib puag ncig.
Yog hais tias lub grounding kuj ntawm qhuav-hom transformer tshaj qhov siv, lub xob laim tam sim no tsis tuaj yeem ntws mus rau hauv av thaum lub caij xob laim. Txawm li cas los xij, yog tias qhov hluav taws xob hluav taws xob tau siv rau sab qis-voltage ntawm kev faib khoom qhuav-hom transformer los ntawm cov xaim hauv av, qhov thim rov qab boost voltage yuav siab. Plaub, qhov chaw teeb tsa yog tsim nyog, thiab lub high-voltage arrester yog teem rau ntawm cov hlau nyob ze ntawm lub tes tsho high-voltage ntawm qhuav-hom transformer. Yog li kom ntseeg tau tias xob laim ncaj qha nkag mus rau hauv lub tes tsho transformer. Xyuas kom muaj kev khiav hauj lwm kom raug ua ntej xob laim tsis nkag mus rau qhuav hom transformers. Raws li kev teeb tsa tshwj xeeb thiab cov qauv kev cai ntawm cov khoom siv hluav taws xob, tiv thaiv qhov muag tsis pom kev poob lawv lub ntsiab lus tiv thaiv.
