Ungayibona njani ilahleko ye-dielectric yee-motor windings?

Ukufumanisa ilahleko ze-dielectric kwiinjini yesigaba esithathuUkujijeka kubalulekile ukuqinisekisa ukuthembeka kunye nobomi bexeshaIimoto ze-AC ezine-voltage ephezuluIndlela esebenzayo yokulinganisa oku kukusebenzisa ibhulorho iXilin, isixhobo esikhethekileyo esenzelwe ukuvavanya iipropati ze-dielectric. Ixabiso le-dielectric loss tangent, elidla ngokubizwa ngokuba yi-loss tangent, linika ulwazi ngomgangatho we-insulation ye-motor coil.

Ukuqala inkqubo yokulinganisa, ifoyile ye-aluminium idla ngokusetyenziswa njenge-electrode yokulinganisa. Olu khetho lubangelwe kukuqhuba kakuhle kombane kwe-aluminium kunye nokulula kokusetyenziswa kwayo. Nangona kunjalo, ukusebenza kokulinganisa kuxhomekeke ekubambeni okuqinileyo kwefoyile ye-aluminium kwi-coil insulation. Ukubopha okuqinileyo phakathi kwefoyile kunye ne-insulator kunciphisa izikhewu zomoya kwaye kwandisa ukuchaneka kwedatha eqokelelweyo. Naluphi na ulwahlulo lunokukhokelela ekufundweni okungalunganga, okuphazamisa ukuthembeka kweziphumo.

Nje ukuba i-aluminium foil inamathele ngokuqinileyo, i-dielectric loss tangent inokulinganiswa kusetyenziswa i-Xilin bridge. I-bridge isebenzisa i-alternating current (AC) voltage kwi-motor windings ukuze kuvavanywe iipropati ze-dielectric ze-insulator. Idatha evelisiweyo inokubonelela ngesalathiso semeko ye-insulation, ityhile naluphi na ukonakala okanye iindawo ezinokubakho zokungaphumeleli.

Ukubeka esweni rhoqo i-tangent yokulahleka kwe-dielectric kubalulekile ekugcinweni kwangaphambili. Ngokuchonga utshintsho kwiimpawu ze-dielectric ngokuhamba kwexesha, amaqela olondolozo anokuthatha amanyathelo okukhawulezisa ukusombulula imiba yokufakelwa kwe-insulation ngaphambi kokuba ikhokelele ekungasebenzi kakuhle kwemoto. Oku akupheleli nje ekuphuculeni ukusebenza kakuhle kwemoto kodwa kwandisa nobomi bayo benkonzo.

Ngamafutshane, ukusebenzisa i-Xilin bridge kunye nee-electrodes zefoyile ye-aluminium ukubona ukulahleka kwe-dielectric yei-motor induction yamanqanaba amathathuIiwindings yindlela ethembekileyo yokuvavanya umgangatho we-insulation. Ukuqinisekisa unxibelelwano oluqinileyo phakathi kwe-foil kunye ne-insulator kubalulekile ekufumaneni idatha echanekileyo nengakhethi cala yokulinganisa, ekugqibeleni inegalelo ekugcinweni ngokufanelekileyo kwee-motors ze-AC high voltage.
