I-Tester yokunyangwa i-Tester ilungele ukulinganisa ixabiso lokuxhathisa izinto ezahlukeneyo zokuthambisa kunye nokunganyangeki kombane, ukuqinisekisa ukuba ezi zixhobo zisebenza kwiimeko eziqhelekileyo zokuthintela ukothusa umbane, izixhobo kunye nezixhobo Umonakalo.
Iingxaki eziqhelekileyo zemibuzo yokunyangwa i-intersetion imi ngolu hlobo lulandelayo:
1. Xa ukulinganisa umthwalo we-IbangeIti yeCaware, buyintoni ubudlelwane phakathi kwemveliso yesekethe i-timenti yokufakelwa i-tester kunye nedatha elingayo, yaye ngoba?
Ubungakanani bemveliso yesekethe i-suble yangoku i-inshontente yokunyangwa bungabonisa ubungakanani bokuchasana kwangaphakathi kwe-voltage ephezulu ngaphakathi kwe-megger.
Uvavanyo oluninzi oluninzi lujolise kwimithwalo yeCawative, njengeentambo ezinde, iikoto ezinemimoya engaphezulu, kunye nabaguquki. Ke, xa ujoliso olulinganiswa lunezixhobo, ekuqaleni kwenkqubo yovavanyo, umthombo wamavoti oPhezulu kwi-Tester Ukulinganisa i-Dester ihlawulisa i-camocial Ukuhlawula i-camocial Ukuhlawula i-Capacial Ukuhlawula i-camocial Ukuhlawula i-Capacial Ukuhlawula i-Capacial Ukuchasana nevolthi yokukhuphela i-voltage kwi-voltage kwimveliso eyongezelelweyo yevolthi. I-Tester yokunyangeka. . Ukuba ixabiso lokuxhobisa lethagethi elilinganisiweyo likhulu, okanye ukunganyangeki kwangaphakathi komthombo wamavoti obuphezulu kuphambi, inkqubo yokubiza iya kuthatha ixesha elide.
Ubude bayo bunokugqitywa yimveliso ye-R engaphakathi kunye ne-C
Ke ngoko, ngexesha lovavanyo, kubalulekile ukuba ubize umthwalo onjalo kwi-voltage yovavanyo, kwaye isantya sesantya se-DV / DT silingana nomyinge we-Charting kwi-CHAKITE YOKWENZA INDAWO YOKUGQIBELA I-C. Yi-DV / DT = NDIYABONA.
Ke ngoko, ukuncipha okuncinci nokuxhathisa kwakhe kunye nokukhonza bukhali, ngokukhawuleza iziphumo zovavanyo ziya kuzinza.
2. Uyintoni umsebenzi we "g" yembonakalo? Kwi-voltage ephezulu kunye nendawo yovavanyo oluphezulu lokuxhathisa, kutheni kufuneka iqhagamshele "g" engapheliyo?
Isiphelo se "g" somphezulu sisiphelo esikhuselayo. Umsebenzi we-termilting themilting kukususa impembelelo yomanyano kunye nobumdaka kwindawo yovavanyo kwiziphumo zemilinganiselo. I-terminal yangaphandle "g" i-terminal ye-leakuge yangoku yemveliso evavanyiweyo, ukuze ukuvuza okwangoku kungadlulanga kwisekethe yovavanyo lwangaphandle, kwaye isuse impazamo ebangelwa kukuvuza okwangoku. I-G teminal isetyenziswa xa kuvavanywa ukumelana okuphezulu.
Ngokubanzi, i-terminal ingaqwalaselwa ngaphezulu kwe-10g. Nangona kunjalo, uluhlu lokuxhathisa aluqinisekanga. Xa icocekile kwaye yomile kwaye ivolumu yento yovavanyo incinci, inokuzinza ngaphandle kokulinganisa i-500g kwindawo ephela. Kwiimeko ezinomswakama kunye nemilambo, ixabiso elingaphantsi lokuchasana nalo lifuna ukuphela. Ngokukodwa, ukuba ufumanisa ukuba iziphumo kunzima ukuzinza xa zisithintele ukunganyangeki okuphezulu, unokujonga usebenzisa i-g terminal. Qaphela ukuba isiphelo sendlela esikhuselayo ayixhunyiwe kwi-wired therefing, kodwa kwi-imenteeter phakathi kwe-l kunye ne-e okanye kwi-wire enamagqabi amaninzi, hayi kwezinye iingcingo eziphantsi kovavanyo.
3. Kutheni kungafuneki kuphela ukulinganisa ixabiso elingachanekanga xa kumiswa, kodwa nokulinganisa umyinge we-abriting kunye nesalathiso sepoliji. Yintoni inqaku?
I-PI yisalathiso sendalo, esibhekisa kuthelekiso phakathi kokunyangwa kwemizuzu eli-10 kunye nokunyangwa komzuzu omnye ngexesha lovavanyo lokufakelwa;
I-Dar yindawo yokuthabatha i-Deelectric, eyabhekisa kuthelekiso phakathi kokunyangwa komzuzu omnye kunye nokunyangwa kwezibuko ze-15s ngexesha lovavanyo lokufakelwa;
Kuvavanyo lokufakelwa, ixabiso lokufakelwa i-intermance ngexesha elithile alinakubonakalisa ngokupheleleyo umsebenzi wokufakelwa kwesampulu yovavanyo. Oku kungenxa yezi zizathu zibini zilandelayo. Kwelinye icala, ukunyangwa kokufakwa komsebenzi omnye wezinto zokufakwa kuncinci xa ivolumu inkulu. , Ukunganyangwa kokufakelwa kuvela xa ivolumu incinci. Kwelinye icala, izinto zokuthambisa zinenkqubo yomyinge we-absit kunye nenkqubo yokulinganisa yentlawulo emva kokuba kusetyenziswa i-voltage ephezulu. Ke ngoko, inkqubo yamandla ifuna ukuba umlinganiso womlinganiso we-abssio-umyinge we-R60mis kunye ne-R15s, kunye ne-Indes ye-polarimin kunye ne-R1min, kunye ne-R1min kwi-R1min, kunye nokusebenzisa le nto Idatha yokuchonga i-fanser elungileyo okanye embi.
4. Kutheni le nto i-Tester ye-imeyile ingayivelisi i-DC ephezulu ye-DC ephezulu xa ixhaswa ziibhetri? Oku kusekwe kumgaqo wokuguqulwa kwe-DC. I-voltage ephantsi yokubonelela ngamandla iphakanyiswe kwimveliso ephezulu ye-DC voltage ngokunyanzeliswa kwesekethe. I-voltage ephezulu evelisiweyo iphezulu kodwa amandla okukhupha amancinci (amandla asezantsi kwaye amancinci okwangoku).
Qaphela: Nokuba amandla amancinci kakhulu, akukhuthazwanga ukuba achukumise uphononongo lovavanyo, kuya kubakho imvakalelo yokuthoba.
