01 Nheyo yeKushanda kweMafusi Ekudonha
Nheyo huru yekushanda kwemafusi anodonha ndeyekushandisa overcurrent kupisa nekunyungudutsa chinhu chefuse, nokudaro zvichityora circuit uye kudzivirira michina yemagetsi kubva mukukuvadzwa.
Kana paine overload kana short circuit mucircuit, fault current inoita kuti fuse ipise nekukurumidza. Kana yasvika panzvimbo yekunyunguduka, inonyunguduka uye fuse tube inodonha yega, zvichiita kuti pave nenzvimbo yakajeka yekuputsika, iyo iri nyore kuti vashandi vekugadzirisa vaone nzvimbo yefault.
Dhizaini iyi haingopi mabasa ekudzivirira akavimbika chete, asiwo inoita kuti nzvimbo yezvikanganiso ionekwe nekukurumidza, zvichideredza zvakanyanya nguva yekugadzirisa nekugadzirisa, uye zvichiwedzera kuvimbika kwesimba remagetsi.
02 Huru Huru dzeUnyanzvi
Mafuyusi emazuva ano anodonha ane hunhu hwakawanda hwakanaka. Anoshandisa zvinhu zvefuyusi zvinofambisa simba zvakanyanya, anopindura nekukurumidza, uye anogona kunyunguduka nekukurumidza kana paine circuit pfupi kana overload.
Fuse inodonha ine hunhu hwayo hwekutyoka, inoenderana nezvinodiwa neIEC, uye inoita kuti ishande zvakanaka. Magadzirirwo ayo echimiro anoita kuti chubhu yefuse idonhe yega mushure mekutyoka, zvichiita kuti pave nenzvimbo yakajeka yekubvisa zvikanganiso kuti zvive nyore kuona nzvimbo yezvikanganiso.
Chivharo ichi chakagadzirwa nezvinhu zvinodzivirira kupisa zvine simba guru uye zvinodzivirira mamiriro ekunze akasimba, zvakakodzera nharaunda dzakaoma dzekunze. Zviri nyore kuisa, uye dhizaini yaro yehukuru hudiki inoshanda kune akasiyana-siyana mamiriro emagetsi. Chivharo chekuisa chinoenderana nacho chinoita kuti kuvaka kuve nyore uye kunoderedza mari yekugadzirisa.
03 Kushandiswa Kwetekinoroji Itsva
Mumakore achangopfuura, tekinoroji yemafusi anodonha yagara ichivandudzwa. Fusi inodonha inochinjika yemagetsi yakapihwa mvumo neHaosheng Electric Power inoita kuti chubhu yefusi itenderere uye idonhe pasina kudonha pasi nekutyoka.
Patent yefuse inodonha yakawanikwa neHebao Electric ine nzira itsva yekudhonza-ring, iyo inoderedza zvinobudirira kuoma kwevashandisi pavanoshandisa tsvimbo inodzivirirwa kudhonza chubhu yefuse, zvichiwedzera nyore uye kuchengetedzeka kwekushanda.
"Fuse yekudonhedza zvinhu zvine hungwaru" yakatangwa neZhejiang inobatanidza kuwandisa kwezvinhu, ma "short circuit", mabasa ekunyevera anodziya zvakanyanya uye kugona kutumira data risingashandise waya, zvichiita kuti mashandiro edhijitari ave epamusoro uye kupa ruzivo rwekushanda kwemidziyo panguva chaiyo ye "smart grid".
04 Maitiro Akajairika Ekushandisa
Mafuyusi anodonhedza magetsi anoita basa guru mumagridi emagetsi ekumaruwa, achishandiswa mumitsetse yekugovera ye12kV kuchengetedza michina yakaita sematransformer nematavi emagetsi.
Munzvimbo dzekugovera magetsi mumaguta, dzakakodzera mayunitsi makuru ekunze, mabhokisi emapazi nezvimwewo, zvichiwedzera kuvimbika kwemagetsi. Munzvimbo yekushandisa simba mumaindasitiri, dzinopa dziviriro yemagetsi akawandisa uye yepfupi kumafekitori, migodhi nedzimwe nzvimbo.
Kana ikashandiswa pamwe chete nechinodzivirira mheni, fuse inodonha inogona kugadzira sisitimu yekudzivirira ine mativi: panguva yekurohwa kwemheni, chinodzivirira mheni chinovhara overvoltage; kana fault current ikaramba iripo mushure mekunge chinodzivirira mheni chakundikana, fuse inoparadzanisa chikamu chakakuvara kudzivirira cascading faults.
05 Mazano Ekusarudza Nekuchengetedza
Pakusarudza fuse inodonha, tanga wasarudza voltage yakakodzera uye current zvichienderana nezvinodiwa chaizvo.
Kuchenjerera kunofanira kupihwa pakusimbiswa kwechigadzirwa kuti uve nechokwadi chekuti zvigadzirwa zvinotevedzera mitemo yenyika nemitemo yeindasitiri, zvakaita seIEC 60282-1 standard 10. Sarudza vatengesi vane vimbiso yakanaka yebasa rekutengesa mushure mekutengesa kuti uve nechokwadi chekushandiswa kwenguva refu pasina kunetseka 1.
Panyaya yekugadzirisa, dhizaini yekudonha kwemagetsi inobatsira panowanikwa zvikanganiso uye inoderedza nguva yekudzima kwemagetsi. Gara uchiongorora mamiriro efuse, kunyanya kana mamiriro ekunze akaipisisa, kuti uve nechokwadi chekuti inoshanda zvakanaka. Kune mafuse ane hungwaru ekudonha kwemagetsi, zvakakoshawo kutarisisa kana basa ravo rekutumira data rakajairika.
