Yuav ua li cas tiv thaiv cam khwb cia resin transformer?
Qhuav hom cam khwb cia resin transformer yog ib hom tshwj xeeb ntawm transformer uas tuaj yeem ua haujlwm yam tsis muaj roj transformer. Muaj ntau ntau hom qhuav-hom transformers, vim nws yog huv si, ib puag ncig tus phooj ywg, thiab tuaj yeem ua haujlwm yam tsis muaj roj transformer. Yog li ntawd, kev siv qhuav-hom cam khwb cia resin transformers Tus nqi kuj tseem loj. Common dry-type transformers xav tau kev tiv thaiv dav, kom lawv qhov kev ua tau zoo tuaj yeem ua tiav ntau dua. Dab tsi yog cov txheej txheem tiv thaiv rau cov tshuab ziab khaub ncaws qhuav?
General qhuav-hom cam khwb cia resin transformer tiv thaiv muaj xws li: ceev-so, dhau-tam sim no, xoom-sequence thiab lwm yam kev tiv thaiv.
1. Ceev ceev tiv thaiv
Kev tiv thaiv ceev ceev yog kom kov yeej lub sijhawm ua haujlwm ntev ntawm cov cuab yeej tiv thaiv ze ntawm lub zog hluav taws xob kawg ntawm kev tiv thaiv overcurrent. Nws txais cov txheej txheem ntawm kev txhim kho tus nqi thiab txwv txoj kev npaj ua los tiv thaiv kab. Muaj peb hom kev tiv thaiv kev tiv thaiv: kev tiv thaiv hluav taws xob ceev ceev, kev tiv thaiv tam sim no sai, thiab kev tiv thaiv hluav taws xob sib txawv ceev ceev.
2. Kev tiv thaiv overcurrent
Ntau cov khoom siv hluav taws xob muaj qhov ntsuas tam sim no, thiab tsis pub dhau qhov ntsuas tam sim no, txwv tsis pub lub cuab yeej yuav raug hlawv. Yog li ntawd, qee cov khoom siv tau ua ib qho kev tiv thaiv tam sim no. Thaum qhov tam sim no tshaj qhov teeb tsa tam sim no, cov cuab yeej yuav cia li kaw lub hwj chim los tiv thaiv cov khoom siv.
3. Zero sequence tiv thaiv
Kev tiv thaiv xoom-sequence txhais tau hais tias tom qab qhov kev ua txhaum hauv av tshwm sim nyob rau hauv qhov loj luv luv-circuit tam sim no hauv av, yuav muaj xoom-sequence tam sim no, xoom-sequence voltage thiab xoom-sequence zog. Cov khoom siv hluav taws xob no yog siv los ua ib lo lus dav dav rau cov khoom siv tiv thaiv relay uas tiv thaiv cov av luv luv.
Cov saum toj no yog ntau yam kev tiv thaiv kev ntsuas thiab ntau yam kev tiv thaiv ntawm hom qhuav-hom transformers. Hais txog kev tiv thaiv ntawm qhuav-hom transformers, peb yuav tsum tsis tu ncua txhim kho txoj kev tiv thaiv, thiab ua ib txoj hauj lwm zoo ntawm kev tiv thaiv ntawm qhuav-hom transformers nyob rau hauv txhua yam. Lub zog thiab kev ua haujlwm ntawm hom transformer txuas ntxiv txhim kho.
