Ukuvuza kwangoku kubhekiselele koKuyilwe ngoku kuMphakathi oNgqongileyo okanye oKhuselweyo oPhakathi kwezahlulo zentsimbi ezigqunywe enye kwenye, okanye phakathi kwezahlulo eziPhilayo kunye neeNdawo eziGrounded, xa kungekho siphene ekusetyenzisweni kombane.KuMgangatho we-US we-UL, ukuvuza kwangoku kungokunje okunokuthi kuqhutywe ukusuka kwiNqanaba eliFikelelayo leZixhobo zeKhaya ezibandakanya ukuQhutywa kweCapacitive yangoku.Ukuvuza kwangoku kuqulethwe ngamacandelo amabini, enye yi-Conduction yangoku i-I1 Ngokuchasene ne-Insulation;Enye kukufuduswa ngoMbane osasaziweyo i-I2 yangoku, i-Capacitive Reactance yeyokugqibela yi-XC=1/2pfc iLungelana ngokuPhambisekayo noBuninzi boMbane, kwaye iCapacitance esasaziweyo iyanyuka ngokunyuka kwe-Frequency, ke ukuvuza kwangoku. Ukonyuka ngokunyuka koMbane waMandla.Umzekelo: Ukusebenzisa i-Thyristor ukunika amandla, i-Harmonic yayo Ubunzima be-Wave yokwandisa ukuvuza kwangoku.
Ukuba iNkqubo-eLawulwayo yokuvuza kwangoku iTester iHlola uMsebenzi we-Insulation weSekethe okanye iNkqubo, le yangoku ibandakanya yonke into edlula kwi-Insulating Material.
Ukongeza kwiNdawo yangoku eHamba eMhlabeni (okanye iNdawo yokuQhubela ngaphandle kweSekethe), kufuneka iphinde ibandakanye iNdawo yangoku eHamba eMhlabeni ngokusebenzisa iZixhobo zeCapacitive kwiSekethe okanye kwiNkqubo (iCapacitance eSasaziweyo inokuthathwa njengeZixhobo zeCapacitive).I-Wiring emide izakwenza iSahluko esikhulu ngakumbi kwaye yandise ukuvuza kwangoku.Oku kufuneka kuqwalaselwe ngakumbi kwiNkqubo engasekelwanga.
Umgaqo-siseko wokulinganisa ukuvuza kwangoku ngokusisiseko uyafana nokulinganisa ukuchasana kwe-Insulation.Ukulinganisa ukuchasana kwe-Insulation ngokwenene luhlobo lokuvuza kwangoku, kodwa lubonakaliswa ngendlela yokuchasa.Nangona kunjalo, uMlinganiselo oQhelekileyo wokuvuza kwangoku uSebenzisa iVolthage yoNxibelelwano, ngoko ke ukuvuza okukhoyo kuyalinganiswa.
Icandelo langoku liqulathe ubunzima obunamandla ngoku.
Ngexesha lokuHlolwa kweVoltage, ukuze kugcinwe izixhobo zoVavanyo kwaye ujonge iZalathi zobuGcisa ngokweMithetho, kukwayimfuneko ukuvuma ukuba amandla ombane oMbane oPhezulu angonakalisi isixhobo esiphantsi kovavanyo (i-Insulation Material) Hambisa ngesiXhobo esiphantsi koVavanyo (iMathiriyeli yokugquma)* Ixabiso elikhulu langoku, eli langoku libizwa ngokuba kukuvuza kwangoku, kodwa le ndlela isetyenziswa kuphela kwezi zihlandlo zikhethekileyo zingentla.Nceda Ulumkele Umahluko.
Inkqubo eLawulwayo yokuvuza yangoku iTester yiSekethi yoMbane okanye iSixhobo esiMpompoza ngeNqanaba le-Insulation ngaphandle kweziphene kunye nombane oFakelweyo.
Okwangoku.Ke ngoko, Yenye yeZalathi eziBalulekileyo ukulinganisa i-Insulation yezixhobo zoMbane, kwaye siSiphawuli esiPhambili soMsebenzi woKhuseleko lweMveliso.
Gcina ukuvuza kwangoku kwixabiso elincinci, elidlala indima ebalulekileyo kuMsebenzi woKhuseleko lweeMveliso eziPhambili.
I-Programmable Leakage yangoku yoMvavanyi isetyenziselwa ukulinganisa ukuvuza okukhoyo ngoku okungabalulekanga kuMsebenzi oveliswe nguMbane wokuSebenza (okanye olunye unikezelo lwaMandla) lweSixhobo soMbane ngokusebenzisa i-Insulation okanye ukusasazwa kweParameter Impedance, kunye ne-Impedance yayo yokufaka ilinganisa ukukhuselwa koMntu. Umzimba.
Ukuvuza kwangoku uMhloli wenziwa ikakhulu kuGuquko lwe-Impedance, uGuqulo loLudwe, uGuqulo lwe-AC-DC, Ukwandiswa, uKubonisa izixhobo, njl.njl. Abanye bakwanazo noLondolozo lwangoku, iSandi kunye nokuKhanya kweeSekethi zeAlarm kunye neZixhobo zoVavanyo zokuCwangciswa kombane, kunye nezixhobo zabo ezibonisa iSixhobo Kwi-Analog kunye neDijithali Iindidi ezimbini.
Into ebizwa ngokuba yi-Touch yangoku, ngokufutshane, ibhekiselele kwiNqanaba eQhubela iNgxowa-mali yeMetal yesixhobo ngoMzimba woMntu ukuya kwiNqanaba eliGrounding okanye iCandelo elichukumisayo.Kule nto, kufuneka siyisebenzise xa kujongwa iSekethe yokuLingisa uMzimba woMntu, iVoltmeter yeParallel, kunye neSekethe yoMlinganiso woMzimba woMntu uneeSekethe zoMlinganiso woMzimba woMntu owahlukileyo ngokweMimiselo yoKhuseleko lweMveliso eyahlukeneyo.
Kukho Iindidi ezine zokuvuza kwangoku: iSemiconductor Component Ukuvuza kwangoku, ukuBonelwa koMbane okuvuza ngoku, ukuvuza kweCapacitor ngoku kunye nokuvuza kwangoku.
Igama lesiTshayina: Ukuvuza kwangoku;Igama langaphandle: Ukuvuza kwangoku
Ukuvuza oku-1 kwangoku kwaMacandelo eSemiconductor
2 Ukuvuza kwamandla ngoku
I-3 ye-Capacitor Leakage yangoku
4 Ukuvuza kwangoku
1. Ukuvuza kwangoku kweeSemiconductor Components
Incinci kakhulu yangoku iqukuqela kwi-PN Junction Xa Icimile.Xa i-DS ibekwe kwi-Bias ePhambili kunye ne-GS i-Reverse Bias, emva kokuba i-Conductive Channel ivuliwe, yangoku iya kuhamba ukusuka ku-D ukuya ku-S. Kodwa enyanisweni, ngenxa yobukho bee-electron zasimahla, ii-Electron zasimahla zincanyathiselwe kwi-SIO2 kunye ne-N+, ibangela DS Ukuvuza yangoku.
2. Ukuvuza kwamandla ngoku
Ukuze kuncitshiswe ukuphazamiseka kwiSibonelelo soMbane woTshintsho, ngokweMigangatho yeSizwe, iSekethe yeFilter ye-EMI kufuneka ifakwe.Ngenxa yoQhagamshelwano lweSekethe ye-EMI, Kukho iNdawo eNcinci kuMgangatho emva kokuba uBonelelo lwaMandla oTshintsho luQhagamshelwe kuBonelelo loMbane, okuKuvuza ngoku.Ukuba ayiculwanga, iqokobhe leKhompyutha liya kuba neVoltage ye-Volts eyi-110 ukuya phantsi, kwaye liya kuziva lindindis xa liphathwa ngesandla, eliya kuchaphazela nokusebenza kweKhompyutha.
3. Ukuvuza kweCapacitor yangoku
I-Capacitor Medium ayinakugqwesa kwi-Non-Conductivity.Xa i-Capacitor isetyenziswe nge-DC Voltage, i-Capacitor iya kuba nokuvuza kwangoku.Ukuba ukuvuza kwangoku kukhulu kakhulu, i-Capacitor iya konakaliswa ngubushushu.Ukongeza kwi-Electrolytic Capacitors, Ukuvuza kwangoku kwezinye iiCapacitors kuncinci kakhulu, ngoko ke iParameter yokuLawula i-Insulation isetyenziselwa ukubonisa umsebenzi wayo wokufakela;Kwaye i-Electrolytic Capacitor inokuvuza okukhulu ngoku, ngoko ke ukuvuza kwangoku kusetyenziselwa ukubonisa umsebenzi wayo we-Insulation (ngokuhambelana nomthamo).
Ukusebenzisa i-Voltage eyongezelelweyo ye-DC kwi-Capacitor iya kuqaphela ukuba ukutshaja kwangoku kuyatshintsha kakhulu, kwaye emva koko kuncipha ngexesha.Xa ifikelela kwiXabiso elithile lokugqibela, iXabiso lokugqibela langoku elifikelela kwiMeko eZinzileyo ibizwa ngokuba yiLeakage yangoku.
Okwesine, Ukuvuza Kwesihluzi Ngoku
Inkcazo yokuvuza kwangoku kweSihluzo soBonelelo lwaMandla kukuba: Ngoku ukusuka kwiSihluzo seSihluzo ukuya kwisiphelo esingenasizathu soNxibelelwano oluNgenayo phantsi koMbane woNxibelelwano oloNgezelelweyo.
Ukuba zonke iizibuko zesihluzi zikhuselwe ngokupheleleyo kwiZindlu, iXabiso lokuvuza kwangoku lixhomekeke ngokuyintloko ekuvuzeni kwangoku kwe-Common-Mode Capacitor CY, oko kukuthi, ngokuyintloko kuxhomekeke kuMmandla weCY.
Ngenxa yokuba iSihluzo esivuzayo sangoku siNxulumene noKhuseleko loBuqu, Onke amazwe asehlabathini aneMimiselo engqongqo kuwo: Kwi-220V/50Hz yoNxibelelwano lweGridi yeSibonelelo saMandla, ukuvuza kwangoku kwesihluzo sengxolo kuyafuneka ukuba kube ngaphantsi kwe-1mA.
