Ukuvuza Kwamanje Kubhekise Kokwamanje Okwakhiwa Ngokuzungeza Okumaphakathi Noma Okuvamisile Phakathi Kwezingxenye Zensimbi Ezivaleleke Kokunye, Noma Phakathi Kwezingxenye Eziphilayo Nezingxenye Eziphansi, lapho Kungekho Isici Ekusetshenzisweni Kwe-Voltage.E-US UL Standard, Ukuvuza Kwamanje Yimanje Okungenziwa Kusuka Engxenyeni Efinyelelekayo Yempahla Yasendlini Kubandakanya Ukuhlanganisa Okunamandla Kwamanje.Ukuvuza Kwamanje Kuqukethe Izingxenye Ezimbili, Eyodwa I-Conduction Yamanje I1 Ngokuphikisana Nokufakwa Kwe-Insulation;Okunye Ukuthuthwa Ngekhono Elisatshalalisiwe I-I2 Yamanje, Ukusabela Okunamandla Kokugcina I-XC=1/2pfc Ilinganisa Ngokuphambene Nemvamisa Yamandla, Futhi Umthamo Osabalalisiwe Wamanje Ukhuphuka Ngokunyuka Kwemvamisa, Ngakho Ukuvuza Kwamanje Inyuka Ngokunyuka Kwemvamisa Yamandla.Isibonelo: Ukusebenzisa i-Thyristor Ukuze Unikeze Amandla, I-Harmonic Yayo Isisindo Segagasi Sandisa Ukuvuza Kwamanje.
Uma Umhloli Wamanje Wokuvuza Okulawulwa Ngohlelo Ehlola Umsebenzi Wokushisisa Wesekethe Noma Uhlelo, Lokhu Kwamanje Kuhlanganisa Konke Okudlula Kumpahla Yokugqumisa.
Ngaphezu kwalokho Okugeleza Kwamanje Emhlabeni (Noma Ingxenye Yeconductive Ngaphandle Komjikelezo), Kufanele Futhi Ifake Okukhona Manje Okugeleza Emhlabeni Ngamadivayisi Anamandla Kusekethe Noma Uhlelo (Amandla Asatshalalisiwe Angathathwa Njengamadivayisi Anamandla).Izintambo Ezinde Zizokwakha Ukusabalalisa Okukhudlwana Umthamo Futhi Kukhuphule Ukuvuza Kwamanje.Lokhu Kufanele Kuqaphe Kakhulu Kuhlelo Olungenasisekelo.
Umgomo Wokukala Ukuvuza Kwamanje Ngokuyisisekelo Kuyafana Nokulinganisa Ukumelana Nokufakwa Kwe-Insulation.Ukulinganisa Ukumelana Ne-Insulation Empeleni Kuwuhlobo Lokuvuza Kwamanje, Kodwa Kuvezwa Ngendlela Yokumelana.Nokho, Isilinganiso Esivamile Sokuvuza Kwamanje Sisebenza I-Voltage Yokuxhumana, Ngakho Ukuvuza Kwamanje Kuyakalwa.
Ingxenye Yamanje Iqukethe Isisindo Esinamandla Samanje.
Ngesikhathi Sokuhlolwa Kwe-Voltage, Ukuze Ugcine Izinto Zokuhlola Futhi Uhlole Izinkomba Zobuchwepheshe Ngokuvumelana Nemithetho, Kuyadingeka Futhi Ukuvuma Ukuthi Amandla Enkundla Ephakeme Kagesi Angalimazi Izinto Ezisetshenziswa Ngaphansi Kokuhlolwa (I-Insulation Material) Ivunyelwe Dlulisa Izinto Ezingaphansi Kokuhlolwa (Into Yokushisisa)* Inani Lamanje Elikhulu, Leli Lamanje Libizwa Ngokujwayelekile Libizwa Ngokuthi Ukuvuza Kwamanje, Kodwa Le Ndlela Isetshenziswa Kuphela Ezikhathini Ezicacisiwe Ezingenhla.Sicela Uqaphele Umehluko.
Umhloli Wamanje Wokuvuza Okulawulwa Ngohlelo Empeleni Umjikelezo Kagesi Noma Izisetshenziswa Ezigeleza Engxenyeni Yokushisisa Ngaphandle Kokulimala Kanye Nogesi Osetshenziswayo.
Okwamanje.Ngakho-ke, Ingenye Yezinkomba Ezibalulekile Zokukala Ukufakwa Kwezinto Ezisebenza Kagesi, Futhi Kuyinkomba Eyinhloko Yomsebenzi Wokuphepha Komkhiqizo.
Gcina Ukuvuza Kumanje Ngenani Elincane, Okudlala Indima Ebalulekile Kumsebenzi Wokuphepha Wemikhiqizo Eya Phambili.
I-Programmable Leakage Current Tester Isetshenziselwa Ukukala Ukuvuza Kwamanje Okungahambisani Nokusebenza Okukhiqizwe Ukunikezwa Amandla Okusebenza (Noma Okunye Ukunikezwa Amandla) Kwento Esebenza Kagesi Nge-Insulation Noma I-Distributed Parameter Impedance, Futhi I-Impedance Yayo Yokokufaka Ilingisa Ukuphazamiseka Komuntu. Umzimba.
Isihloli Samanje Sokuvuza Sihlanganiswe I-Impedance Conversion, Range Conversion, AC-DC Conversion, Ukunwetshwa, Ebonisa Izisetshenziswa, Njll. Okunye Futhi Banokugcinwa Okungaphezu Kwamanje, Amasekhethi E-alamu Okukhanya Kanye Nezisetshenziswa Zokuhlela Amandla Kagesi Wokuhlola, Kanye Nemishini Yazo Ebonisa I-Dividedp Ku-Analog kanye Nezinhlobo Ezimbili Zedijithali.
Okubizwa ngokuthi I-Touch Current, Ngamafuphi, Ibhekisela Kokwamanje Okugeleza Ngengxenye Yensimbi Ethintekayo Yedivayisi Ngomzimba Womuntu Kuya Engxenyeni Ephansi Noma Ingxenye Ethintekayo.Kulokhu, Kufanele Siyisebenzise Lapho Sihlola Isekethe Yokulingisa Umzimba Womuntu, I-Parallel Voltmeter, Kanye Nesekhethi Yokulingisa Umzimba Womuntu Ineziyingi Zokulingisa Umzimba Womuntu Ezihlukile Ngokuvumelana Nemithetho Ehlukile Yokuphepha Komkhiqizo.
Kunezinhlobo Ezine Zokuvuza Kwamanje: Ukuvuza Kwengxenye Yamanje Ye-Semiconductor, Ukuvuza Kwamanje Kokuhlinzekwa Kwamandla, Ukuvuza Kwe-Capacitor Okwamanje Kanye Nokuvuza Kwamanje.
Igama lesiShayina: Ukuvuza Kwamanje;Igama Langaphandle: Ukuvuza Kwamanje
1 Ukuvuza Kwamanje Kwezingxenye Ze-Semiconductor
2 Ukuvuza kwamandla kwamanje
3 I-Capacitor Ukuvuza Kwamanje
4 Hlunga Ukuvuza Kwamanje
1. Ukuvuza Kwamanje Kwezingxenye Ze-Semiconductor
Okuncane Kakhulu Kwamanje Kugeleza Ku-PN Junction Uma Ivaliwe.Lapho I-DS Isethelwe Phambili I-Bias Futhi I-GS Ihlehla Eceleni, Ngemva Kokuvulwa Kwesiteshi Esiqhutshwayo, Okwamanje Kuzogeleza Kusuka ku-D kuye ku-S. Kodwa Eqinisweni, Ngenxa Yokuba Khona Kwama-electron Amahhala, Ama-electron Amahhala Anamathiselwe Ku-SIO2 kanye No-N+, Okubangela I-DS Ukuvuza Kwamanje.
2. Ukuvuza kwamandla kwamanje
Ukuze Unciphise Ukuphazamiseka Ekunikezeni Amandla Okushintsha, Ngokusho Kwezinga Likazwelonke, Isekethe yesihlungi se-EMI Kumele Kufakwe.Ngenxa Yokuxhunywa Kwesekethe ye-EMI, Kukhona Okwamanje Kancane Phansi Ngemva Kokushintshwa Kwamandla Okuxhunywa Ekuhlinzekweni Kwamandla, Okuwukuvuza Kwamanje.Uma Ingagayiwe, I-Computer Shell izoba ne-Voltage ye-Volts engu-110 phansi, futhi Izozizwa Indikindiki Uma Ithintwa Ngesandla, Okuzophinde Kuthinte Ukusebenza Kwekhompyutha.
3. Ukuvuza Kwe-Capacitor Yamanje
I-Capacitor Medium Ayinakuba Yinhle Kakhulu Ekungaqhubini.Lapho I-Capacitor Isetshenziswa Nge-DC Voltage, I-Capacitor Izoba Nokuvuza Kwamanje.Uma Ukuvuza Kwamanje Kukhulu Kakhulu, I-Capacitor Izolinyazwa Ukushisa.Ukwengeza Kuma-Electrolytic Capacitors, Ukuvuza Kwamanje Kwamanye Ama-Capacitors Kuncane Kakhulu, Ngakho-ke Ipharamitha Yokumelana Ne-Insulation Isetshenziselwa Ukubonisa Umsebenzi Wayo Wokumisa;Futhi I-Electrolytic Capacitor Inokuvuza Okukhulu Kwamanje, Ngakho Ukuvuza Kwamanje Kusetshenziselwa Ukubonisa Umsebenzi Wayo Wokushisisa (Ngokulingana Nekhono).
Ukusebenzisa I-Voltage Eyengeziwe Yokusebenza kwe-DC Ku-Capacitor Kuzoqaphela Ukuthi Ukushaja Kwamanje Kushintsha Kakhulu, Bese Kwehla Ngokuhamba kwesikhathi.Uma Ifinyelela Inani Lokugcina Elithize, Inani Lokugcina Lamanje Elifinyelela Isimo Esizinzile Libizwa Ngokuthi Ukuvuza Kwamanje.
Okwesine, Ukuvuza Kwamanje Kwesihlungi
Incazelo Yokuvuza Kwamanje Kwesihlungi Sokuphakela Amandla Ithi: Okwamanje Kusukela Kukesi Lokuhlunga Kuya Esiphethweni Esingenamthetho Solayini Ongenayo Wokuxhumana Ngaphansi Kogesi Owengeziwe Wokuxhumana.
Uma Wonke Amachweba Esihlungi Evalekile Ngokuphelele Kusuka Endlini, Inani Lokuvuza Kwamanje Lincike Ngokuyinhloko Ekuvuzeni Kwamanje Kwe-Common-Mode Capacitor CY, Okusho ukuthi, Ngokuyinhloko Kuncike Emandleni E-CY.
Ngenxa yokuthi Ukuvuza Kwamanje Kwesihlungi Kuhlobene Nokuphepha Komuntu Siqu, Wonke Amazwe Emhlabeni Anemithetho Eqinile Kuso: Ngokunikezwa Amandla Egridi Yezokuxhumana engu-220V/50Hz, Ukuvuza Kwamanje Kwesihlungi Somsindo Ngokuvamile Kudingeka Ukuba Kube Ngaphansi Koku-1mA.
