Ukuxhathisa ukugquma kwemoto yiparameter ephambili yokuvavanya ukusebenza kwayo kwe-insulation, ehambelana ngokuthe ngqo nokusebenza okukhuselekileyo kwemoto. Ngenxa yeentlobo ezahlukeneyo kunye namanqanaba ombane weenjini, ubuncinci bemigangatho yokumelana nokugquma kwahlukile.
Ukumelana ne-insulation yeemoto eziphantsi-voltage
Kuba injini ene-voltage ephantsis enamanqanaba ombane angama-400V nangaphantsi, eyona migangatho isezantsi yokuxhathisa ukugquma imi ngolu hlobo lulandelayo:
Imigca emitsha ebekwe ngokutsha: Ukumelana nokufakelwa kwe-insulation phakathi kwemigca naphakathi kwemigca kunye nomhlaba akufanele kube ngaphantsi kwe-0.5 megohms.
Izixhobo kunye nemigca esebenzayo: Ukuxhatshazwa kwe-insulation akufanele kube ngaphantsi kwe-1 megohm / kilovolt, okanye ukulingana ne-1 kiloohm / volt.
Ukumelana ne-insulation yeenjini ezincinci kunye neziphakathi
Kwiimoto ezincinci kunye nobukhulu obuphakathi ngokubanzi, umgangatho ophantsi wokumelana nokufakwa kwe-insulation awukho ngaphantsi kwe-0.5 megohms. Lo mgangatho usebenza kwizixhobo kunye nemigca esebenzayo, kwaye ukuchasana kwe-insulation akufanele kube ngaphantsi kwe-1MΩ/kV.
Ukumelana ne-Insulation yei-high-voltage motor yombanes
Iimfuno zokumelana nokufakwa kwe-insulation kwiimotor ezinevoltage ephezulu zingqongqo. Imigangatho ethile yile ilandelayo:
Ukumelana ne-stator insulation: Kwiqondo lokushisa lokusebenza, ukuchasana kwe-insulation akufanele kube ngaphantsi kwe-1 megohm nge-kilovolt.
Ukumelana nokugquma kwe-rotor: Ukumelana nokufakelwa kwayo akufanele kube ngaphantsi kwe-0.5 megohms ngekhilovolthi.
Umlinganiselo wokunganyangeki kwe-motor insulation
Xa eneneni ulinganisa ukuxhathisa ukugquma kwenjini, kunokubakho umahluko othile ngenxa yereferensi yemigangatho eyahlukeneyo kunye neempembelelo zezinto ezinje ngobushushu kunye nomlinganiselo wokufunxa. Ngokukodwa xa ixabiso lokumelana ne-insulation kunye ne-absorption ratio isondele kwixabiso elibalulekileyo, iziphumo zovavanyo lwabaqhubi abahlukeneyo zinokwahluka. Ngoko ke, xa ulinganisa, imimiselo echaphazelekayo kufuneka ilandelwe ngokungqongqo, isixhobo esifanelekileyo kufuneka sikhethwe, kwaye iimfuno ezihlukeneyo zomda weendawo ezibandayo kunye nezishushu kufuneka zihlulwe.
Isishwankathelo, ubuncinci bomgangatho wokuchasa ubushushu bemoto buxhomekeke kwinqanaba lombane kunye nohlobo. Ukumelana nokufakwa kwe-insulation motors low-voltage motors kunye neemotor ezincinci neziphakathi /Injini yokungenisa amandla ombane aphakathi ngokuqhelekileyo kufuneka ukuba ingabi ngaphantsi kwe-0.5 megohms, ngelixa ukuxhatshazwa kwe-insulation yeenjini eziphezulu ze-voltage akufanele kube ngaphantsi kwe-1 megohm ngekhilovolthi. Le migangatho ijoliswe ekuqinisekiseni ukuba i-motor ayiyi kubangela iingozi zokhuseleko ngenxa yokungabikho ngokwaneleyo kwe-insulation ngexesha lokusebenza.
