Isitolo esidayisa yonke impahla 12KV Zw32-12F uchungechunge ongaphandle AC high vacuum ohlakaniphile wesifunda full VCB umphakeli

Isifinyezo

hw32-12F uchungechunge ongaphandle AC high vacuum ohlakaniphile wesifunda breaker (ngemuva kwalokhu obizwa ngokuthi wesifunda full) kufanelekile 12kV nangaphansi, AC 50H2 idolobha inethiwekhi futhi emaphandleni uhlelo amandla ukusatshalaliswa. Inomsebenzi wokuthola iphutha, umsebenzi wokulawula ukuvikela nomsebenzi wokuxhumana. Ifakwe endaweni yokuklama isibopho somugqa ongaphezulu kwe-12kV, engabona ukusika okuzenzakalelayo, isisekelo esisodwa sokugxila kanye ne-othomathikhi yokuhlukaniswa okuzenzakalelayo kwephutha lesifunda. Ilungele ukuguqulwa kwamandla kagesi okusatshalaliswa nokwakhiwa kwenethiwekhi okuzenzakalelayo. umkhiqizo

Isiphuli sesekethe singasebenza ngesandla, siqhutshwe ngogesi, siqhutshwe kude futhi siqhutshwe kude. Ikhefu lesifunda lakhiwa izingxenye ezintathu: umzimba, indlela yokusebenza kanye ne-controler. Iswishi yokuzihlukanisa ifakwa ngumsebenzisi. Isiphuli sesekethe singalungiswa nge-CT protection transformer yamanje) iZCT (Zero-sequence current transformer) ne-PT (Voltage Transformer) njengomtshina wesilawuli.
