Resistancess na Tester ya dace da aunawa darajar tsayayya da kayan haɗin, motors, nazarin lantarki, masu amfani da kayan lantarki don guje wa yanayin lantarki don guje wa mawuyacin hali, raunin da aka yi da kayan Lalacewa.
Matsaloli na gama gari na tsayayya da Tester sune kamar haka:
1. Lokacin da ake amfani da juriya mai nauyi, menene dangantakar da ke tsakanin gajeren yanayin yanayin tashin hankali mai gwaji da kuma aka auna?
Girman fitarwa na gajeren yanayin halin tsayayya da tester na iya nuna girman juriya na mai ƙarfin lantarki a cikin megger.
Yawancin rufaffiyar suna gwada rijables masu ƙarfi, irin su na biyu na fi'ido, motors tare da ƙarin iska, da masu canzawa. Sabili da haka, lokacin da aka nada wanda aka auna yana da ƙarfi, a farkon tsarin gwajin, mai ƙarfin lantarki a cikin yanayin juriya ta hanyar lalacewa, kuma sannu a hankali cajin wutar lantarki na Rufin juriya na tester. . Idan karfin karfin da aka auna yana da girma, ko juriya na babban mai ƙarfin lantarki yana da girma, tsarin caji zai ɗauki lokaci mai tsawo.
Za a iya tabbatar da tsayinsa ta samfurin r inner da C kaya (naúrar: na biyu), wannan shine, t = r come * c kaya.
Saboda haka, yayin gwajin, ya zama dole a cajin irin wannan nauyin da ke tattare da shi ga wutar lantarki, da DV / DT = I / c.
Sabili da haka, ƙananan juriya da kuma mafi girman caji, da sauri sakamakon gwajin zai zama barga.
2. Menene aikin "G" na bayyanar? A cikin babban-voltage da babban yanayin gwaji, me yasa ake buƙata don haɗa "G" tashar waje?
The "g" ƙarshen farfajiya shine tashar kariya. Aikin tashar kare kariya ita ce cire tasirin zafi da datti a yanayin gwaji akan sakamakon edime. A waje "G" tashar jiragen ruwa ta hanyar lalacewa na halin da aka gwada, saboda lalacewa a halin yanzu ba ta wuce kuskuren gwajin na waje ba, da kuma kawar da kuskuren gwajin da ke haifar da lalacewa. Ana amfani da tashar g anallan lokacin da gwaji mai tsauri.
Gabaɗaya magana, za a iya la'akari da tashar gyarawa don sama da 10g. Koyaya, wannan yanayin jure ba tabbas bane. Lokacin da yake da tsabta kuma bushe da kuma ƙarfafawar gwajin ƙarami karami ne, zai iya zama mai tsayayye ba tare da auna 500g a g ƙarshen. A cikin yanayin datti da datti, ƙimar juriya yana buƙatar ƙarshen G. Musamman, idan kun ga cewa sakamakon yana da wuya a shirya tsari lokacin da yake auna juriya, zaku iya bincika amfani da gassal. Hakanan lura cewa tashar kare kariya g ba ta haɗa da Layer Layer, amma ga insultort tsakanin l da e ko zuwa wani waya mai sassauci, ba ga sauran wayoyi a ƙarƙashin gwaji ba.
3. Me yasa ba kawai buƙatar auna darajar juriya lokacin da aka faɗi rufin ba, har ma don auna rufafar shan sha da kuma auna nauyin sha da polarization. Menene ma'anar?
Pi alama ce ta pi, wanda ke nufin kwatancen tsakanin rufin rufin minti 10 da kuma juriya na minti 1 a lokacin rufin gwajin;
Dar shi ne Ratin Kula da Ayyuka na Sheeprica sha tsakanin tudun juriya na 1 na minti 1 da rufin tsayayya da 15s a cikin rufin da aka gwada;
A cikin rufin rufin, tayin tsayar da ƙwararrun ƙimar a wani ɗan lokaci ba zai iya yin la'akari da yanayin samfurin gwaji ba. Wannan shi ne saboda dalilai biyu masu zuwa. A gefe guda, rufin lalacewa na aikin iri ɗaya na kayan rufin yana ƙarami lokacin da ya girma. , Resistance Resistance ya bayyana lokacin da ƙarawa ya karami. A gefe guda, kayan insulating yana da tsarin ɗaukar matakan sha da polarization na cajin bayan an yi amfani da babban wutar lantarki. Saboda haka, tsarin wutar yana buƙatar ma'aunin raguwar sha-r60s da r15s, da R1min a cikin rushewar manyan transformers, igiyoyi, motoci da sauran lokatai, kuma amfani da wannan Bayanai don sanin rufin mai kyau ko mara kyau.
4. Me yasa za su iya tsayayya da kayan lantarki na lantarki mai girma na lantarki mafi girma DC babban ƙarfin lantarki lokacin da batura da yawa batura suka yi? Wannan ya dogara ne da ƙa'idar rajistar DC. Ana tayar da karancin wutar lantarki na wutar lantarki zuwa mafi girman fitarwa DC voltage ta hanyar haɓaka sarrafawa. Babban wutar lantarki ya haifar da mafi girma amma fitarwa ikon ƙarami ne (ƙarancin kuzari da ƙananan halin yanzu).
SAURARA: Ko da ikon yana da ƙanƙanta, ba da shawarar taɓa binciken gwajin ba, to har yanzu zai kasance tsayayyen abin mamaki.
