1.Kutheni i-transformer core kufuneka isekelwe?

Xa i-transformer isebenza, umbindi wentsimbi, umbindi wentsimbi ozinzileyo, kunye nesakhiwo sesinyithi sokujika, iindawo, izinto, njl. zonke zikwintsimi yombane enamandla. Phantsi kwesenzo sombindi wombane, zinamandla aphezulu omhlaba. Ukuba umbindi wentsimbi awukagalelwanga, kuya kubakho umahluko onokubakho phakathi kwayo kunye ne-grounded clamp kunye netanki yepetroli. Phantsi kwesenzo somahluko onokubakho, ukukhutshwa okukhawulezileyo kunokwenzeka.

Ukongeza, xa i-transformer isebenza, kukho amandla amakhulu emagnethi ajikeleze i-winding. Umbindi wesinyithi, isakhiwo sesinyithi, iindawo, izinto, njl. zonke zikwintsimi yemagnethi engalinganiyo. Umgama phakathi kwazo kunye ne-winding awulingani. Ke ngoko, nganye nganye Ubukhulu bamandla e-electromotive abangelwa yintsimi yemagnethi yezakhiwo zesinyithi, iindawo, izinto, njl. nazo azilingani, kwaye kukwakho umahluko onokubakho phakathi komnye nomnye. Nangona umahluko onokubakho ungemkhulu, unokuqhekeza umsantsa omncinci wokufakelwa, onokubangela nokukhupha i-micro-discharge rhoqo.

Nokuba yinto yokukhupha umoya ngexesha elithile enokubangelwa yimpembelelo yomahluko onokubakho, okanye yinto eqhubekayo yokukhupha umoya kancinci ebangelwa kukwaphuka komsantsa omncinci wokukhusela, akuvumelekanga, kwaye kunzima kakhulu ukujonga iindawo zezi zinto zokukhupha umoya ngexesha elithile.

Isisombululo esisebenzayo kukugalela ngokuthembekileyo umbindi wesinyithi, umbindi wesinyithi ozinzileyo, kunye nezakhiwo zesinyithi ezijikelezayo, iindawo, izinto, njl.njl., ukuze zibe kwindawo efanayo yomhlaba netanki yepetroli. Umbindi wetransformer umi kwindawo enye, kwaye unokugalela kuphela kwindawo enye. Ngenxa yokuba amaphepha esinyithi esilicon ombindi wesinyithi agqunywe ngxinano, oku kukuthintela ukuveliswa kwemisinga emikhulu ye-eddy. Ke ngoko, onke amaphepha esinyithi esilicon akufuneki ami kwindawo enye okanye ami kwindawo enye. Ngaphandle koko, imisinga emikhulu ye-eddy iya kubangelwa. Umbindi ushushu kakhulu.

Umbindi wesinyithi we-transformer uphantsi komhlaba, ngesiqhelo naliphi na iqhekeza lesinyithi se-silicon kwisiseko sesinyithi liphantsi komhlaba. Nangona amaphepha esinyithi e-silicon efakwe i-insulation, amaxabiso awo okumelana nobushushu mancinci kakhulu. Intsimi yombane enamandla engalinganiyo kunye nentsimi enamandla yemagnethi zinokwenza ukuba iitshaja ze-voltage eziphezulu ezibangelwa kumaphepha esinyithi e-silicon zihambe ukusuka emhlabeni ziye emhlabeni ngokusebenzisa amaphepha esinyithi e-silicon, kodwa zinokuthintela imisinga ye-eddy. Zihamba ukusuka kwelinye iqhekeza ukuya kwelinye. Ke ngoko, lo gama nje naliphi na iqhekeza lesinyithi se-silicon kwisiseko sesinyithi liphantsi komhlaba, lilingana nokufaka isiseko sesinyithi sonke.

Kufuneka kuqatshelwe ukuba umbindi wesinyithi we-transformer kufuneka usekelwe kwindawo enye, kungekhona kwiindawo ezimbini, kodwa ngaphezulu kwiindawo ezininzi, kuba ukusekelwe kwiindawo ezininzi yenye yeempazamo eziqhelekileyo ze-transformer.2.Kutheni i-transformer core ingenakuqiniswa kwiindawo ezininzi?

Isizathu sokuba ii-laminations ze-transformer core zikwazi ukuxhonywa kwindawo enye kuphela kukuba ukuba kukho iindawo zokuxhonywa ezingaphezu kwesibini, i-loop inokwenziwa phakathi kweendawo zokuxhonywa. Xa umzila ophambili udlula kule loop ivaliweyo, kuya kuveliswa umsinga ojikelezayo kuwo, obangela ingozi ngenxa yokushisa okungaphakathi. I-iron core yendawo enyibilikisiweyo iya kwenza i-short-circuit fault phakathi kwee-iron chips, eya kwandisa ukulahleka kwe-iron, eya kuchaphazela kakhulu ukusebenza kunye nokusebenza okuqhelekileyo kwe-transformer. I-iron core steel sheet ye-silicon kuphela enokutshintshwa ukuze ilungiswe. Ke ngoko, i-transformer ayivumelekanga ukuba ixhonywe kwiindawo ezininzi. Kukho umhlaba omnye kuphela.

3. Ukusikwa kwe-multi-point kulula ukwenza umsinga ojikelezayo kwaye kulula ukuvelisa ubushushu.

Ngexesha lokusebenza kwe-transformer, iindawo zesinyithi ezifana ne-iron core kunye nee-clamps zonke zikwintsimi yombane enamandla, kuba i-electrostatic induction iya kuvelisa amandla okudada kwi-iron core kunye neendawo zesinyithi, kwaye le power iya kuphuma emhlabeni, into engamkelekanga. Ke ngoko, i-iron core kunye nee-clips zayo kufuneka zibekwe ngokuchanekileyo nangokuthembekileyo (ngaphandle kwee-core bolts kuphela). I-iron core ivunyelwe kuphela ukuba ibekwe kumgangatho omnye. Ukuba amanqaku amabini okanye ngaphezulu abekwe kumgangatho, i-iron core iya kwenza i-closed loop ene-grounding point kunye nomhlaba. Xa i-transformer isebenza, i-magnetic flux iya kudlula kule closed loop, eya kuvelisa oko kubizwa ngokuba yi-circulating current, okubangela ukugqithiswa kakhulu kwe-iron core, kunye nokutsha kweendawo zesinyithi kunye nee-insulating layers.

Ngamafutshane: umbindi wesinyithi wetransformer unokuqiniswa kwindawo enye kuphela, kwaye awunakuqiniswa kwiindawo ezimbini okanye ngaphezulu.
