Abakhiqizi bepayipi le-epoxy bethula i incazelo yezinto zokuvikela

Ngokwendinganiso kazwelonke ye-GB2900.5, incazelo yezinto zokwakha i-insulating ithi: “izinto ezisetshenziselwa ukuvikela ugesi ngogesi”. Okungukuthi, i-insulating material evimbela ukudlula kukagesi. Ukumelana kwayo kuphezulu kakhulu, ngokuvamile kububanzi obungu-10-10Ω·m. Njengasemotweni, okokuvikelayo okuzungeze amakhondatha kuhlukanisa amajika kanye nomgogodla we-stator osekelwe phansi ukuze kuqinisekiswe ukusebenza okuphephile kwenjini.

Izinto ezakhiwe ngezinto ezine-resistivity engu-109 kuya ku-1022 Ω•Cm zibizwa ngokuthi izinto ezivikelayo kubuchwepheshe bukagesi, okwaziwa nangokuthi ama-dielectrics. Kalula nje, kuyinto ehlukanisa umzimba oshajiwe kwezinye izingxenye. I-insulating material inokumelana okukhulu kakhulu ne-DC yamanje. Ngaphansi kwesenzo se-voltage ye-DC, empeleni ayisebenzi ngaphandle kwendawo encane kakhulu evuzayo yamanje. Ku-AC yamanje, kukhona i-capacitive current edlulayo, kodwa futhi ibhekwa njengengaqhubeki. I-Conductive. Ukuphakama kokumelana kwezinto zokuvikela, kuba ngcono ukusebenza kwe-insulating.

Kubuchwepheshe bukagesi, izinto zokuvikela imvelo ngokuvamile zibhekisela ezintweni ezinokumelana okukhulu kuno-10 kuya kumandla we-9th Ω.cm. Umsebenzi wezinto zokufaka i-insulating ngokuyinhloko ukuhlukanisa izingxenye ezibukhoma zamandla ahlukene emishini kagesi.

Ngakho-ke, izinto zokufaka i-insulating kumele zibe nezakhiwo ezinhle ze-dielectric, okungukuthi, kufanele zibe nokumelana okuphezulu kwe-insulation namandla okucindezela, futhi zikwazi ukugwema izingozi ezifana nokuvuza, i-creepage kanye nokuphuka; okwesibili, ukumelana nokushisa kwezinto zokufaka i-insulating kungcono, ikakhulukazi ku-Kuqinisekisiwe ukuthi ngeke kube nezinguquko zokusebenza ngenxa yokushisa isikhathi eside; ngaphezu kwalokho, ine-conductivity enhle yokushisa, ukumelana nomswakama, amandla aphezulu emishini, nokucubungula okulula.

Izinto zokuvikela i-insulation ezivame ukusetshenziswa ngogesi zingahlukaniswa zibe izinto ezingaphili kanye nezinto eziphilayo ngokuya ngezakhiwo zamakhemikhali ezahlukahlukene. Kunezinhlobo ezintathu ze-insulating materials kanye nezinto ezixubile zokuvikela.
