Abanye abathengi, xa betyelela umzi-mveliso, baphakamisa umbuzo wokuba ingaba iimveliso zeemoto zinokuphinda zivavanywe ngoxinzelelo lwe-dielectric standing voltage. Lo mbuzo ubuye wabuzwa ngabasebenzisi abaninzi beemoto. Uvavanyo lwe-dielectric standing voltage luvavanyo lokufumanisa ukusebenza kwe-insulation ye-motor windings ngexesha lokucubungula imveliso, kunye novavanyo lwemveliso yomatshini wonke. Ikhrayitheriya yokugweba isiqinisekiso kukuba i-insulation ayiphulwanga phantsi kweemeko ezithile.
Ukuqinisekisa ukuba ukusebenza kokugquma injini kuyahlangabezana neemfuno, ukongeza ekukhetheni ucingo olufanelekileyo lwe-electromagnetic kunye nezixhobo zokugquma, iziqinisekiso zenkqubo ezinokuthenjwa nazo ziyafuneka. Umzekelo, ukhuseleko ngexesha lokucubungula, izixhobo ezifanelekileyo, izixhobo ezifanelekileyo zokugquma, kunye neeparamitha zenkqubo ezifanelekileyo.
Xa sithatha ii-windings zeemoto ezine-high-voltage njengomzekelo, uninzi lwabavelisi beemoto baya kwenza uvavanyo lwe-turn-to-turn kunye ne-dielectric standing voltage kwi-coil nganye. Ngaphambi kokufakelwa, i-core ene-windings kunye nomatshini wonke ngexesha lovavanyo lokuhlolwa ziya kuphononongwa nge-dielectric standing voltage. Oku kusibuyisela kumathandabuzo abathengi abanawo malunga nomba we-dielectric standing.
Ngokwenyani, uvavanyo lwe-dielectric standing voltage luvavanyo olutshabalalisayo olungenakuguqulwa. Nokuba kukwi-windings okanye kwi-coil nganye, akukhuthazwa ukwenza uvavanyo oluphindaphindwayo, kunye nesidingo sokufumana iingxaki njengesiseko. Kwiimeko ezikhethekileyo apho kufuneka uvavanyo oluphindaphindwayo, i-voltage yovavanyo kufuneka incitshiswe ngokweemfuno ezifanelekileyo zomgangatho ukuze kuncitshiswe umonakalo kwi-insulation kangangoko kunokwenzeka.
Ngokuphathelele iDielectric Withstand Voltage Tester
Isixhobo sokuvavanya i-dielectric standing voltage sisixhobo sokulinganisa amandla e-dielectric standing voltage. Sinokuvavanya ngokuchanekileyo, ngokukhawuleza, nangokuthembekileyo izalathisi ezahlukeneyo zokusebenza kokhuseleko lombane ezifana ne-standing voltage, i-breakdown voltage, kunye ne-leaking current yezinto ezivavanyiweyo. Ngesixhobo sokuvavanya i-dielectric standing voltage, iingxaki zinokufunyanwa kwaye ukuthotyelwa kokusebenza kwe-insulation kunokufunyanwa.
● Fumana amandla okukhusela ubushushu okumelana ne-voltage esebenzayo okanye i-overvoltage.
● Jonga umgangatho wokwenziwa kwe-insulation okanye ukugcinwa kwezixhobo zombane.
● Susa umonakalo kwi-insulation obangelwa zizinto ezikrwada, ukucutshungulwa, okanye ukuthuthwa, kwaye unciphise izinga lokungaphumeleli kweemveliso kwangethuba.
● Hlola ukuba umbane uvumelekile na kwaye umgama wokufakwa kwe-insulation uyahambelana na.
Imigaqo yokukhetha i-Dielectric Stain Voltage Test Voltage
Eyona ndlela ilungileyo yokufumanisa i-voltage yovavanyo kukuyibeka ngokweemfuno ezifunekayo kuvavanyo. Ngokubanzi, i-voltage yovavanyo ibekwe ngokuphindwe kabini kune-voltage elinganisiweyo kunye ne-1000V. Umzekelo, ukuba imveliso ine-voltage elinganisiweyo ye-380V, i-voltage yovavanyo iya kuba yi-2 x 380 + 1000 = 1760V. Kakade ke, i-voltage yovavanyo inokwahluka ngokuxhomekeke kudidi lwe-insulation kwaye iintlobo ezahlukeneyo zemveliso zineemfuno ezahlukeneyo ze-voltage.
Kutheni kubalulekile ukujonga rhoqo ukuthembeka kwesekethe yovavanyo?
Abavavanyi be-Dielectric standing voltage kumgca wemveliso basetyenziswa rhoqo, ingakumbi iilead zovavanyo kunye nezixhobo zovavanyo ezihlala zihamba, nto leyo eyenza ukuba ziqhelane nokuqhekeka kwentambo yangaphakathi kunye neesekethe ezivulekileyo, eziqhele ukuba nzima ukuzibona. Ukuba kukho isetyhula evulekileyo nangaliphi na ixesha kwi-loop, i-voltage output ephezulu yi-dielectric standing voltage tester ayinakusetyenziswa ngokwenene kwinto evavanyiweyo. Ezi zizathu zinokubangela ukuba i-voltage ephezulu ebekweyo ingasetyenziswa ngokwenene kwinto evavanyiweyo ngexesha lovavanyo lwamandla e-dielectric standing, kwaye ngokwemvelo, umbane ohamba ngento evavanyiweyo uya kuba phantse yi-zero. Ekubeni ungadluli umda ophezulu obekwe yi-dielectric standing voltage tester, isixhobo siya kunika isaziso sokuba uvavanyo lufanelekile, kuthathelwa ingqalelo ukuba i-insulation ifanelekile. Nangona kunjalo, idatha yovavanyo kweli tyala ayiyonyani. Ukuba into evavanyiweyo ineziphene ze-insulation ngeli xesha, iya kukhokelela ekugwebeni okungalunganga okukhulu.
