Fiyuzi inodonhedza rabha yesilicone-27KV

Semhando yefuse inodonha (inozivikanwawo sefuse switch), mafuse edu ekudzivirira transformer akagadzirirwa zviitiko zvekushandiswa zvinosanganisira matransformer ari pamusoro pemagetsi ekuparadzira magetsi uye nzvimbo dzemagetsi. Mafuse aya anonyanya kuve nefuse link uye fuse holder, iyo inoshanda pamwe chete kudzima circuit yega kana magetsi adarika muganho wakachengeteka. Nekukanganisa magetsi asina kunaka nekukurumidza, anodzivirira matransformer kuti asanyanya kupisa uye kukuvara, nokudaro achidzivirira kugadzikana kwese kwesystem yekugovera magetsi. Achishandiswa zvakanyanya pamwe chete nematransformer, mafuse aya akakosha pakuchengetedza kushanda kwakachengeteka kwemidziyo yemagetsi mune ese manetwork ekugovera magetsi uye nzvimbo dzemagetsi.

Mafuyusi edu ekudzivirira matransformer akagadzirwa kuti asvike padanho repamusoro-soro reindasitiri, zvichivimbisa kushanda zvakanaka uye kuvimbika. Anowanikwa mumhando dzakasiyana dzemagetsi nema current ratings, izvo zvinogona kusarudzwa nemazvo zvichienderana ne voltage yakatarwa, rated current, uye breaking capacity zvinodiwa zve transformer nema circuits ayo. Akagadzirirwa kuiswa nyore, ma fuyusi aya anoderedza kuoma kwebasa rekuunganidza panzvimbo. Pamusoro pezvo, ane zvinodiwa zvishoma zvekugadzirisa uye kuvimbika kwenguva refu, anokwanisa kutsungirira mamiriro akaoma ekushanda mumasisitimu ekuparadzira magetsi uye ma utility substations. Kushanda kukuru kwe automatic over current disconnection kunoita kuti fuyusi ikwanise kupindura nekukurumidza kuma fault currents, ichipa dziviriro panguva yakakodzera kuma transformers asati akuvadzwa.

Kuchengetedzeka ndiyo musimboti mukuru wekugadzira mafusi edu ekudzivirira ma transformer. Pakushandisa, ma fusi aya anobvisa otomatiki dunhu kana transformer ikaita zvikanganiso zve overcurrent kana short-circuit, zvichidzivirira njodzi dzakadai sekupisa kwe transformer uye moto unokonzerwa ne overcurrent. Kuti uve nechokwadi chekuchengetedzeka kwakanyanya, zvakakosha kusarudza fuse model yakakodzera zvichienderana ne parameters chaiyo ye transformer (kusanganisira rated voltage, rated current) uye mamiriro ekushanda kwedunhu. Kana yaiswa uye ikashandiswa zvichienderana nemaitiro ekushanda akajairwa, ma fusi edu anoumba chipingamupinyi chekuchengetedza chakavimbika kune ma transformer, zvichideredza njodzi dzetsaona dzemagetsi uye kuchengetedza kuchengetedzeka kwevashandi nemidziyo mu system yekugovera magetsi. Uyezve, dhizaini yechigadzirwa inoenderana nezvinodiwa zvekuchengetedza mumaindasitiri, zvichiwedzera kuchengetedzeka nekugadzikana mukati menguva yayo yebasa.
