Iitransformer ezifakelwe kwi-pad zezo bhokisi zentsimbi eluhlaza kwindawo ohlala kuyo eziguqula umbane we-voltage ephezulu ube yi-voltage ephantsi efanelekileyo kumakhaya nakumashishini. Ezi zinto zibalulekileyo ziqinisekisa ukuba une-voltage efanelekileyo yombane.

Yintoni i-Transformer efakwe kwi-Pad

I-transformer efakwe kwi-pad sisixhobo sombane esibalulekileyo esifakelwe kumgangatho womhlaba, esihlala sibekwe kwi-concrete pad. Ezi ndawo zifumaneka rhoqo kwiindawo zokuhlala nakwiindawo zorhwebo, ezi ndawo ziluhlaza zentsimbi zisebenza ekunciphiseni umbane osebenzisa umbane ophezulu ukusuka kwiintambo zombane ukuya kwi-voltage ephantsi efanelekileyo ukusetyenziswa ekhaya nakwezorhwebo.

Ezifakwe ngaphakathi kwikhabhathi yesinyithi ekhuselayo, ii-transformers ezifakwe kwi-pad zibonelela ngokhuseleko oluphuculweyo kunye nobuhle obuhle xa kuthelekiswa nezinye izinto ezifakwe kwi-pole. Le ndawo ikhusela iyunithi kwimpembelelo yemozulu kwaye inciphisa umngcipheko wokuphazamiseka okanye ukudibana ngengozi nezinto eziphilayo.

Indlela i-Transformer efakwe kwiPad esebenza ngayo

Iitransformer ezifakwe kwi-pad ziguqula umbane we-high-voltage ukusuka kwimigca yokusasaza yokuqala ukuya kwii-voltage eziphantsi ezifanelekileyo ukusetyenziswa kwiindawo zokuhlala nakwiindawo zorhwebo. Ezi transformers zehlisa ii-voltage ukusuka kwi-4,160 ukuya kwi-34,500 volts ukuya kumanqanaba alawulekayo, njenge-120/240 volts emakhaya kunye ne-480 volts kumashishini.

Embindini wetransformer efakwe kwi-pad kukho itransformer ngokwayo, equlathe izinto ezimbini eziphambili: ii-windings eziphambili nezesibini. I-primary winding ifumana igalelo le-voltage ephezulu, edla ngokuba phakathi kwe-4,160 ukuya kwi-34,500 volts. Le winding iqhagamshelwe kuthotho lwee-coils zobhedu okanye ze-aluminium ezijikelezileyo kwi-iron core. I-magnetic field eveliswa yi-current ehamba kwi-primary winding ibangela i-voltage kwi-secondary winding.

I-secondary winding, nayo eyenziwe ngee-coils ze-copper okanye ze-aluminium, yenzelwe inani elithile lee-turns ukuvelisa i-output voltage efunekayo, ngesiqhelo i-120/240 volts kwizicelo zokuhlala okanye i-277/480 volts yokusetyenziswa kwezorhwebo.
