Ungayibona kanjani ilahleko ye-dielectric yama-motor windings?

Ukuthola ukulahleka kwe-dielectric kuinjini yesigaba ezintathuukugoqa kubalulekile ekuqinisekiseni ukuthembeka nokuphila kwesikhathiAma-motor ane-AC ephezuluIndlela ephumelelayo yalokhu kulinganisa ukusebenzisa ibhuloho le-Xilin, ithuluzi elikhethekile elenzelwe ukuhlola izakhiwo ze-dielectric. Inani le-dielectric loss tangent, elivame ukubizwa ngokuthi i-loss tangent, linikeza ukuqonda ngekhwalithi yokufakwa kwe-motor coil.

Ukuze kuqalwe inqubo yokulinganisa, i-aluminium foil ivame ukusetshenziswa njenge-electrode yokulinganisa. Lokhu kukhetha kwakungenxa yokuqhuba kahle kukagesi kwe-aluminium kanye nokulula kokusetshenziswa. Kodwa-ke, ukusebenza kahle kokulinganisa kuncike ekuboshweni okuqinile kwe-aluminium foil ekufakweni kwekhoyili. Ukubopha okuqinile phakathi kwe-foil kanye ne-insulator kunciphisa izikhala zomoya futhi kwandisa ukunemba kwedatha eqoqwe. Noma yikuphi ukuhlukaniswa kungaholela ekufundweni okunephutha, okubeka engcupheni ubuqotho bemiphumela.

Uma i-foil ye-aluminium isinamathele ngokuqinile, i-tangent yokulahlekelwa yi-dielectric ingalinganiswa kusetshenziswa ibhuloho le-Xilin. Ibhuloho lisebenzisa i-voltage yamanje eshintshanayo (AC) kuma-windings emoto ukuze kuhlolwe izakhiwo ze-dielectric ze-insulator. Idatha ekhiqizwayo inganikeza inkomba yesimo se-insulation, iveze noma yikuphi ukuwohloka noma amaphuzu angaba khona okwehluleka.

Ukuqapha njalo i-tangent yokulahlekelwa yi-dielectric kubalulekile ekunakekelweni okubikezelayo. Ngokubona izinguquko ezimpahleni ze-dielectric ngokuhamba kwesikhathi, amaqembu okulungisa angathatha izinyathelo zokuxazulula izinkinga zokufakelwa ngaphambi kokuba ziholele ekulimaleni kwenjini. Lokhu akugcini nje ngokuthuthukisa ukusebenza kahle kwenjini kodwa futhi kwandisa isikhathi sayo sokusebenza.

Ngamafuphi, ukusebenzisa i-Xilin bridge kanye ne-aluminium foil electrodes ukuthola ukulahleka kwe-dielectric kweimoto yokungenisa yesigaba ezintathuAma-windings ayindlela ethembekile yokuhlola ikhwalithi yokufakwa kwe-insulation. Ukuqinisekisa ukubopha okuqinile phakathi kwe-foil kanye ne-insulator kuyisihluthulelo sokuthola idatha yokulinganisa enembile nengakhethi, ekugcineni okunegalelo ekugcinweni kahle kwama-motor e-AC high voltage.
