Ukuthetha malunga nokuvuza okuvunyiweyo

Nangona zombini kuvavanyo lwe-voltagend kunye novavanyo lwangoku olungeyovuza kusetyenziselwa ukuvavanya amandla okuvavanywa kwethagethi ekuvavanyiweyo, kukho umahluko ophambili kwinkqubo yovavanyo kunye neziphumo. Uvavanyo lwe-voltand ye-voltage lwenziwa phantsi kwe-voltage ephezulu emva kokufakelwa kwenkqubo yokufakelwa kwayo yonke indawo ephethe ngayo ivavanyiweyo isondele. Uvavanyo lokuvuza ngokuvuza (Ukuchukumisa okwangoku) kwenziwa phantsi kweemeko zombane usebenzisa izixhobo zokuvavanya ukuxelisa umzimba.

Nangona ezi mvavanyo zimbini zahlukile, ziluncedo kakhulu ekuqinisekiseni ukhuseleko lwemveliso. Uvavanyo lwe-voltand ye-voltage yi-100% yovavanyo lwe-100% (oqhelekileyo), kwaye uvavanyo lwangoku lujongwa njengovavanyo lohlobo.

Ngokwamkelwa ngokubanzi komzali we-voltage yanamhlanje ye-voltage (LVD), kuhlolwe uvavanyo lwe-voltage kunye nokuvuya ngoku

Iimveliso zombane ezikumgangatho ophezulu kufuneka zidlulise uvavanyo lwemigangatho yokhuseleko kwiinkalo ezininzi, kubandakanya uvavanyo lokulinganisa i-voltage, uvavanyo lwe-inshonter, i-Exper. Uvavanyo lwangoku (uhlolo lwangoku). Le mveliso inokulinganisa ukuvuza okungaqhelekanga ngoku kuvavanyo lwangoku. Ukuvuza i-tester yangoku sisixhobo sovavanyo oluqhelekileyo lovavanyo lwangoku.

Ukusebenza okuvuza ivuza (Chukumisa okwangoku)
Kwiminyaka yakutshanje, Imigaqo emininzi yoKhuseleko lweMveliso ifuna ukuba iimveliso zivavanywe ngokuvuza okwangoku, nokuba kuvavanyo lwe-ID okanye uvavanyo lwemveliso, ngakumbi kwinqanaba loyilo. Emva kwezi mvavanyo, iinjineli zoyilo zemveliso zinokufumana ulwazi oluninzi olubalulekileyo malunga nemveliso yemveliso, ukwenza ukuba imveliso ihambelane nemigaqo yokhuseleko. Xa ithagethi evavanyiweyo ivavanywa phantsi kwe-voltage eyongeziweyo okanye i-1.1 amaxesha okukhupha i-voltage eqhelekileyo, oko kukuthi, xa imveliso ivavanywa ngokufanelekileyo, kucingo oluzinzileyo lovavanyo oluvavanyiweyo Ukulinganiswa ukuqinisekisa ukuhamba kokuhamba kwe-okwangoku kumda wenkqubo. Kuvavanyo lweeKhabhinethi ezivuzayo ngoku, okwangoku ukusuka kwiindawo ezahlukeneyo kwiKhabhinethi kwindawo engathathi cala kwinkqubo ilinganiswe.

I-Intertand ye-voltage (i-insulliser) kukuxelisa inkqubo yokufakelwa kwethagethi evavanyiweyo kufuneka ikwazi ukumelana ne-voltage ephezulu kangangexesha elingaphaya kokusetyenziswa kwesiqhelo. Imveliso yemveliso yemveliso ye-voltage kuthetha ukuba inokusebenza ngokukhuselekileyo kwindawo eqhelekileyo kwaye inokumelana notshintsho oluqhelekileyo lokutshintsha. Olu luvavanyo oluluncedo ngokubanzi, kunye nabavelisi beemveliso banokuyisebenzisa ukuqinisekisa uphawu lwemveliso yomsebenzisi.

In A Simple Test Combination, The Connection Between The Withstand Voltage Tester And The Tested Target Can Pass Through The Socket Box Or The Test Lead, And Then The Withstand Voltage Tester Applies Voltage To The Tested Target. Ukuba ukuvuza okudlulayo kuphakathi kukhulu kakhulu, i-test ye-voltage iya kubonisa iziphoso, ebonisa ukuba ithagethi ekuvavanyiweyo ayiphunguli. Ukuba akukho kuvavanywa okugqithisileyo ngokugqithisileyo, i-test ye-teststage iya kubonisa ukuba ngoku idlulile, ebonisa ukuba ithagethi ekuvavanyiweyo sele ihambile uvavanyo. Ixabiso lemivumo egqithisileyo igqitywe lixabiso lemigangatho yenqanaba elivumelekileyo langoku, elinokuhlengahlengiswa kwi-Intertand ye-voltage ukuqinisekisa ukuba kudlule khona uvavanyo. I-test ye-voltage ye-voltage igxile kwimigangatho yokufakelwa phakathi kwabaqhubi abaphetheyo kwangoku kwaye bangathathi ntweni aboni, njengokuthwaza izinyithi ezingekho mthethweni. Le yeyona ndlela ilungileyo yokufumana iingxaki zoyilo zemveliso, njengokubeka abaqhubi kufutshane kakhulu.

Iimeko zokusebenza zomsebenzi ze-voltage voltage yovavanyo lwe-leakie
I-Leagege-ilawulwa nge-leakuge evunyiweyo ngokugqibeleleyo, imigaqo yokhuseleko kunye nemibutho elawulayo ayinalo ixabiso lokuvavanywa rhoqo, kodwa igqitywe ngumenzi wemveliso evavanyiweyo. Ukuba ubuninzi be-voltage ye-voltage leakagey ixabiso elingachazwanga, Phantsi kovavanyo.

I-Intertand ye-voltage ukuvuza okwangoku * Ukucaciswa ngokubanzi ngokhuseleko kunye neenkcazo zinokubhekisa kwiNkcazo ye-UL ye-UL, ngokubanzi "njengereferensi. Oku kuchazwa kuseta ukumelana okusisigxina, ngokuqinisekileyo okuya kukhokelela kwisalathiso sempazamo kuvavanyo lwe-voltage. Kwinqanaba lokuqala, i-1000 volts vols kunye ne-voltage eyongezelelweyo yezixhobo ecaleni kwe-quldil. Esi sisicwangciso esiqhelekileyo sokuvavanywa kwe-voltage. Ukususela kwi-voltage eyongezelelweyo yeethagethi zovavanyo ezininzi ezisetyenziswa eUnited States yi-120

Kuvavanyo lokuvuza ngokuvuza, ukulinganiswa okwangoku kunokusetyenziselwa ukubala ixabiso elifanelekileyo lohambo lwangoku lokugcina uvavanyo lwe-voltage. Eli lixesha elifanelekileyo, ngenxa yokuphambuka kwezinto zezixhobo kunokubangela umahluko omncinci ukufundwa kwangoku zeethagethi zovavanyo ezahlukeneyo. Xa kubalwa ukubala usetyenziso lwangoku, kubaluleke kakhulu ukuqonda umahluko osisiseko phakathi kovavanyo lwe-voltage kunye novavanyo lwangoku. Nangona uninzi lwe-testers ezivuzayo lubonelela nge-intanethi (L / n) iguqule i-swings, ilinganisa kuphela ukuvuza okwangoku ukusuka kwicandelo lentembelo langoku kwimeko yesixhobo esiphantsi kovavanyo kunye. I-netrestage voltage yovavanyo lokuvuza ngokuvuza kwezinto ezimbini ezithe tyaba ngokudibeneyo, ngaloo ndlela zibonisa ukufundwa okuphezulu. Umgaqo oluncedo wesithupha kukuseta uhambo lwe-voltage ye-voltage ngoku ukuya kuthi ga kwi-20% ukuya kwi-25% ye-25% yeziphumo zobalo lwefomula:
