Abavelisi bemibhobho ye-epoxy bazisa i Inkcazo yezinto zokukhusela

Ngokomgangatho wesizwe we-GB2900.5, inkcazo yezinto zokukhusela: “izinto ezisetyenziselwa ukudibanisa izixhobo zombane”. Oko kukuthi, i-insulating material ethintela ukuhamba kombane. Ukuxhathisa kwayo kuphezulu kakhulu, ngokuqhelekileyo kuluhlu lwe-10-10Ω·m. Njengoko kwi-motor, izinto ezikhuselayo ezijikeleze abaqhubi zihlukanisa ukujika kunye ukusuka kwisiseko esisezantsi se-stator ukuqinisekisa ukusebenza ngokukhuselekileyo kwemoto.

Izinto ezenziwe ngezinto ezinokumelana ne-109 ukuya kwi-1022 Ω•Cm zibizwa ngokuba yimathiriyeli yokugquma kubuchwepheshe bombane, eyaziwa ngokuba yi-dielectrics. Ngamafutshane, yimathiriyeli eyahlula umzimba ohlawulelwayo kwamanye amalungu. Izinto zokugquma zinokumelana okukhulu kakhulu ne-DC yangoku. Phantsi kwentshukumo yombane we-DC, ayisebenzi ngaphandle komphezulu omncinci wokuvuza ngoku. Kwi-AC yangoku, kukho i-capacitive current edlulayo, kodwa ikwathathwa njengento engasebenziyo. Iyaqhuba. Ukuphakama kwe-resistiveivity ye-insulating material, ngcono ukusebenza kwe-insulating.

Kwitekhnoloji yombane, izixhobo zokugquma zihlala zibhekisa kwizinto ezinokumelana ne-resistivity enkulu kune-10 ukuya kumandla we-9th Ω.cm. Umsebenzi wezinto zokugquma i-insulating ikakhulu ukwahlula iindawo eziphilayo zamandla ahlukeneyo kwizixhobo zombane.

Ngoko ke, izinto zokukhusela kufuneka zibe neempawu ezintle ze-dielectric, oko kukuthi, kufuneka zibe nokumelana okuphezulu kwe-insulation kunye namandla okunyamezela, kwaye zikwazi ukuphepha izingozi ezifana nokuvuza, i-creepage kunye nokuphuka; okwesibini, ukuxhathisa ubushushu bezinto zokugquma kubhetele, ikakhulu ku Kuqinisekisiwe ukuba akuyi kubakho utshintsho lokusebenza ngenxa yokufudumeza ixesha elide; Ukongeza, ine-conductivity elungileyo ye-thermal, ukumelana nokufuma, amandla aphezulu omatshini, kunye nokusebenza kakuhle.

Izixhobo ze-insulation eziqhelekileyo ezisetyenziswa ngombane zinokwahlulwa zibe yimathiriyeli ye-inorganic kunye ne-organic materials ngokwemichiza eyahlukeneyo. Kukho iintlobo ezintathu zezinto zokukhusela kunye nezinto ezixubeneyo zokugquma.
