I-Insulation Resistance Tester ikulungele ukulinganisa iXabiso lokuchasa lezinto ezahlukeneyo zokugquma kunye nokunyathela kwiinsulation yeTransformers, Motors, iintambo kunye nezixhobo zoMbane, ukuqinisekisa ukuba ezi ziXhobo, izixhobo zoMbane kunye neeLayini zisebenza kwiimeko eziqhelekileyo ukunqanda ukothuka koMbane. Umonakalo.
Iingxaki eziqhelekileyo ze-Insulation Resistance Tester zezi zilandelayo:
1. Xa ulinganisa ukuchasana komthwalo we-Capacitive, yintoni ubudlelwane phakathi kwesiphumo esifutshane seSekethe yangoku ye-Insulation Resistance Tester kunye neDatha eLinganisiweyo, kwaye kutheni?
Ubungakanani beSiphumo seSekethe esifutshane sangoku soMvavanyi we-Insulation Resistance bungabonakalisa ubungakanani bokuchasana kwangaphakathi koMthombo weVoltge ephezulu ngaphakathi kweMegger.
Iimvavanyo ezininzi ze-Insulation zijolise kwiMilayidi eCapacitive, efana neeCables ezinde, iiMotor ezine-Windings ezininzi, kunye neTransformers.Ke ngoko, xa iThagethi eLinganisiweyo inesakhono, ekuqaleni kweNkqubo yoVavanyo, uMthombo weVoltage ephezulu kwi-Insulation Resistance Tester kufuneka ihlawulise i-Capacitor ngokuchasana kwayo kwangaphakathi, kwaye ngokuthe ngcembe ihlawulise iVoltage ukuya kwisiphumo esongezelelweyo seVoltage ephezulu. I-Insulation Resistance Tester..Ukuba i-Capacitance Value ye-Target Target inkulu, okanye i-Internal Resistance yoMthombo we-High-Voltage mkhulu, Inkqubo yokutshaja iya kuthatha ixesha elide.
Ubude bayo bunokumiselwa nguMveliso we-R Inner kunye ne-C Umthwalo (Iyunithi: Okwesibini), oko kukuthi, T = R Inner * C Umthwalo.
Ngoko ke, ngexesha loVavanyo, kuyafuneka ukuba kuhlawuliswe iCapacitive Load kuVavanyo lweVoltage, kwaye iSpeed sokuTshaja iDV/Dt silingana noRhwebo lokuTshaja ngoku mna kuMtyalo weCapacitance C. Oko kukuthi, DV/Dt= NDIYABONA.
Ke ngoko, okuncinci ukuchasana kwangaphakathi kwaye okuKhulu ukutshaja ngoku, ngokukhawuleza iziphumo zovavanyo ziya kuzinza.
2. Yintoni uMsebenzi wecala elithi “G” leNkangeleko?Kwindawo yoVavanyo lweVoltage ephezulu kunye neHigh-Resistance, Kutheni iyimfuneko ukuQhagamshela iTheminali “G” ngaphandle?
Isiphelo "G" soMphezulu siSitena esikhuselayo.Umsebenzi weSitena esikhuselayo kukususa impembelelo yokufuma kunye nokungcola kwiNdawo yoVavanyo kwiZiphumo zoMlinganiso.Itheminali "G" yangaphandle idlula ukuvuza kwangoku kweMveliso evavanyiweyo, ukuze ukuvuza kwangoku kungadluli kwiSekethe yoVavanyo lwaNgaphandle, kwaye kuphelise impazamo ebangelwe kukuvuza kwangoku.Itheminali ye-G isetyenziswa xa kuVavanywa uKuxhathisa okuPhezulu.
Ukuthetha ngokubanzi, Itheminali ye-G inokuthathelwa ingqalelo ePhakamileyo kune-10G.Nangona kunjalo, olu luhlu lokuchasa aluqinisekanga.Xa icocekile kwaye yomile kwaye iVolume yento yovavanyo incinci, inozinza ngaphandle kokulinganisa i-500G kwi-G End.Kwimekobume efumileyo nemdaka, Ixabiso elisezantsi lokuxhathisa likwafuna iG End.Ngokukodwa, ukuba ufumanisa ukuba iziphumo zinzima ukuzinzisa xa ulinganisa ukuchasana okuPhezulu, ungacinga ngokusebenzisa iG terminal.Kwakhona qaphela ukuba iSitena esiKhuselekileyo G asiQhaganiswanga noMaleko oKhuselayo, kodwa kwisiKhuseli esiPhakathi kwe-L kunye no-E okanye kwiiNcingo eziManinzi, hayi kwezinye iiNcingo eziphantsi kovavanyo.
3. Kutheni kungafuneki nje kuphela ukulinganisa iNqanaba loKuchasa xa ulinganisa i-Insulation, kodwa kunye nokulinganisa i-Absorption Ratio kunye ne-Polarization Index.Yintoni Injongo?
I-PI yi-Polarization Index, ebhekiselele ekuthelekisweni phakathi kwe-Insulation Resistance yemizuzu eyi-10 kunye nokuchasana kwe-Insulation ye-1 ngomzuzu ngexesha loVavanyo lwe-Insulation;
I-DAR yi-Dielectric Absorption Ratio, ebhekiselele ekuthelekisweni phakathi kwe-Insulation Resistance ye-1 Minute kunye ne-Insulation Resistance ye-15s ngexesha loVavanyo lwe-Insulation;
KuVavanyo lwe-Insulation, ixabiso le-Insulation Resistance Ngexesha elithile alikwazi ukubonakalisa ngokupheleleyo umsebenzi we-Insulation weSampuli yoVavanyo.Oku kungenxa yezi zizathu zimbini zilandelayo.Ngakolunye uhlangothi, ukuchasana kwe-Insulation yoMsebenzi ofanayo weMathiriyeli ye-Insulation incinci xa iVolume inkulu., I-Insulation Resistance ibonakala xa iVolume incinci.Ngakolunye uhlangothi, i-Insulating Material ineNkqubo ye-Absorption Ratio kunye neNkqubo ye-Polarization ye-Charge emva kokuba i-Voltage ephezulu isetyenzisiwe.Ke ngoko, iSistim yaMandla ifuna umlinganiselo wokufunxa-umlinganiselo wee-R60 kunye nee-R15, kunye ne-Polarization Index-Umlinganiselo we-R10min kunye ne-R1min kuVavanyo lwe-Insulation yeZiguquli ezingundoqo, iintambo, iiMoto kunye nezinye izinto ezininzi, kwaye usebenzise oku. Idatha yokumisela i-Insulation ilungile okanye imbi.
4. Kutheni i-Electronic Insulation Resistance Tester ikwazi ukuvelisa amandla ombane aphezulu e-DC xa inikwe amandla ziibhetri ezininzi?Oku kusekwe kuMgaqo woGuqulo lweDC.Umbane woBonelelo lwaMandla oMbane oPhantsi unyuselwa kwiMphumo ePhezulu yoMbane we-DC ngokuPhuculwa kweSekethe yoBoost.Umbane oPhezulu oVeliswayo uPhakamileyo kodwa amandla okuphuma aMancinci (Amandla aphantsi kwaye mancinci ngoku).
Qaphela: Nokuba Amandla Mancinci Kakhulu, Akukhuthazwa ukuba Uchukumise Uvavanyo Lovavanyo, Kuseza kubakho ukuvakala kwe-tingling.
