I-Insulation Resistance Tester (ekwabizwa ngokuba yi-Insulation Dual Display Resistance Tester) Ineendidi ezintathu zovavanyo olusetyenziselwa ukulinganisa ukuchasana kwe-Insulation.Uvavanyo ngalunye lusebenzisa iNdlela yalo, lujolise kwiiMpawu eziKhethekileyo ze-Insulation zeDivaysi phantsi kovavanyo.Umsebenzisi kufuneka akhethe eyona ilunge kakhulu kwiiMfuno zoVavanyo.
Uvavanyo lweNqanaba: Olu vavanyo lufanelekile kwiZixhobo ezineempembelelo zeCapacitance ezincinci okanye eziNcinci, ezinje ngocingo olufutshane.
I-Voltage yoVavanyo isetyenziswe kwixesha elifutshane, kude kube kuFundiweyo okuZinzileyo kufikeleleke, kwaye iVoltage yoVavanyo ingasetyenziswa kwixesha elimiselweyo (ngokuqhelekileyo i-60 Seconds okanye ngaphantsi).Qokelela ufundo ekupheleni kovavanyo.Ngokumalunga neeRekhodi zeMbali, iiGrafu ziya kuzotywa ngokusekwe kwiiRekhodi zeMbali zokuFunda.Ukujongwa kweTrendi kuqhutywa kwithuba lexesha, ngokwesiqhelo iminyaka emininzi okanye iinyanga.
Le Quiz yenzelwe iiQuiz okanye iiRekhodi zeMbali.Utshintsho kubushushu kunye nokufuma kunokuchaphazela ufundo, kwaye imbuyekezo iyafuneka xa iyimfuneko.
Uvavanyo lokunyamezela: Olu vavanyo lufanelekile ukuqikelela kunye noKhuseleko loKhuseleko loomatshini abajikelezayo.
Thatha ufundo oluPhumelelekayo ngexesha elithile (ngokuqhelekileyo yonke iMizuzu embalwa) kwaye uthelekise umahluko ekufundweni.I-Insulation eNgqwesileyo iya kubonisa ukonyuka okuQhubekayo kwexabiso lokuchasa.Ukuba ufundo luyama kwaye ufundo alunyuki njengoko kulindelekile, i-Insulation inokuba buthathaka kwaye inokufuna ukuqwalaselwa.I-Insulators ezimanzi kunye nezingcolisekileyo zinokunciphisa ufundo lokuchasa kuba zongeza ukuvuza kwangoku ngexesha lovavanyo.Logama nje kungekho tshintsho lubalulekileyo lobushushu kwisixhobo phantsi kovavanyo, impembelelo yobushushu kuvavanyo inokungahoywa.
Isalathiso sePolarization (PI) kunye neDielectric Absorption Ratio (DAR) Ngokuqhelekileyo isetyenziselwa ukulinganisa iziphumo zeemvavanyo zexesha.
Isalathiso sePolarization (PI)
Isalathiso sePolarization sichazwa njengeRetiyo yexabiso lokuchasa kwiMizuzu eyi-10 ukuya kwixabiso lokuchasa kwiMizuzu eyi-1.Kuyacetyiswa ukuba uSete elona xabiso liphantsi le-PI ye-AC kunye ne-DC yoomatshini abajikelezayo kumaqondo obushushu beKlasi B, F kunye ne-H ukuya ku-2.0, kunye nexabiso eliphantsi le-PI kwiKlasi yeSixhobo kufuneka ibe yi-2.0.
Qaphela: Ezinye iiNkqubo ze-Insulation eziNtsha ziphendula ngokukhawuleza kwiimvavanyo ze-Insulation.Ngokuqhelekileyo baqala kwiziphumo zoVavanyo kuLuhlu lwe-GΩ, kwaye i-PI iphakathi kwe-1 kunye ne-2. Kwezi meko, ukubalwa kwe-PI kunokungahoywa.Ukuba i-Insulation Resistance iPhakamileyo kune-5GΩ kwi-1 ngomzuzu, i-PI eBaliweyo isenokungabi nantsingiselo.
Inyathelo loVavanyo lweVoltage: Olu vavanyo luluncedo ngakumbi xa iVoltage eyongezelelweyo yesiXhobo iphezulu kunoVavanyo olukhoyo loVavanyo lweVoltage oluveliswe yi-Insulation Resistance Tester.
Faka ngokuthe ngcembe amaNqanaba oMbane ahlukeneyo kwisixhobo esiphantsi kovavanyo.UVavanyo olucetyiswayo lweRatiyo yeVoltage ngu-1:5.Ixesha loVavanyo kwiNyathelo ngalinye liyafana, Ngokuqhelekileyo imizuzwana engama-60, ukusuka ezantsi ukuya phezulu.Olu vavanyo luqhele ukusetyenziswa kuVavanyo lweVoltage ePhantsi kuneVoltage eyongezelelweyo yesixhobo.Ukongezwa okuKhawulezayo kwamaNqanaba oMbane woVavanyo kunokubangela uxinzelelo olongezelelweyo kwi-Insulation kunye nokungasebenzi kakuhle kweentsilelo, okukhokelela kumaxabiso aphantsi okuchasa.
Uvavanyo loKhetho lweVoltage
Ekubeni uvavanyo lokumelana ne-Insulation Resistance Test lubandakanya i-Voltage ye-DC ephezulu, kuyafuneka ukuba ukhethe i-Voltage efanelekileyo yoVavanyo ukunqanda uxinzelelo olugqithisileyo kwi-Insulation, enokuthi ibangele ukusilela kwe-Insulation.IVoltage yoVavanyo inokuphinda itshintshe ngokweMigangatho yeHlabathi.
