Ukuvuza kwamanje kubhekiswa kokwakheka kwamanje ngokusebenzisa indawo ezungezile ephakathi nendawo noma yokufaka inyumbana phakathi kwezingxenye zensimbi ezifakwe komunye nomunye, noma phakathi kwezingxenye ezibukhoma kanye nezingxenye ezibukhoma, lapho kungekho sici ekusetshenzisweni kwamandla kagesi. E-US Ul Standard, Ukuvuza Kwamanje kuyinto yamanje engaqhutshwa kusuka engxenyeni efinyelelekayo yemishini yasendlini kufaka phakathi ukuhlangana kwamanje. Ukuvuza kwamanje kuqukethe izingxenye ezimbili, eyodwa ingukuthi i-I1 yamanje ye-I1 ngokusebenzisa ukumelana kokufakelwa; Elinye liwukuhanjiswa nge-capacitance esatshalaliswa i-I2 yamanje, ukuphendula kwe-xc = 1 / 2PFC kulingana kakhulu kumandlandlandla amandla, kanye nokusatshalaliswa kwamakhompiyutha okukhuphuka ngokuningiliziwe kwemvamisa, ngakho-ke ukuvuza kwamanje Kukhuphuka ngokwanda imvamisa yamandla. Isibonelo: Usebenzisa i-thyristor ukuhlinzeka ngamandla, i-almonic yayo isisindo segagasi inyusa i-veage yamanje.
Uma umhloli wamanje wokuvuza olawulwa amathuba ahlola umsebenzi wokufakelwa kwesifunda noma uhlelo, lokhu kuhlanganisa konke okudlula izinto ezifaka ukufakwa.
Ngaphezu kokugeleza kwamanje emhlabathini (noma ingxenye esebenzayo ngaphandle kwesifunda), kufanele futhi ifake ukugeleza kwamanje emhlabeni ngokusebenzisa amadivaysi e-capacitive esifundeni noma esimisweni (ukusatshalaliswa kwamakhono kungabhekwa njengamadivayisi we-capacitive). I-wiring ende izokwakha inqwaba yasabalalisa umthamo futhi yandise i-verage yamanje.Lokhu kufanele ikakhulukazi ngokucophelela ohlelweni olungabi nalo.
Umgomo wokulinganisa ukuvuza kwamanje ngokuyisisekelo kuyafana nokulinganisa ukumelana kokufakelwa. Ukulinganisa ukumelana kokufakwa empeleni kuyindlela yokuvuza yamanje, kepha kuvezwa ngendlela yokumelana. Kodwa-ke, ukukalwa okujwayelekile kokuvuza kwamanje okusebenzayo kwezokuxhumana, ngakho-ke ukuvuza kwamanje kulinganiswa.
Ingxenye yamanje iqukethe isisindo se-capacive samanje.
Ngesikhathi sokuhlola ukuhlola kwe-voltage, ukuze ulondoloze imishini yokuhlola futhi uhlole izinkomba zobuchwepheshe ngokuya ngemithetho, kuyadingeka futhi ukuvuma ukuthi amandla enkambu aphezulu engalimazi imishini ngaphansi kovivinyo (impahla yokufakelwa) ivunyelwe Ukugeleza ngokusebenzisa imishini ngaphansi kovivinyo (impahla yokufakelwa) Sicela wazi umehluko.
Umhloli wamanje wokuvuza olawulwa nguhlelo empeleni ungumjikelezo kagesi noma imishini egeleza engxenyeni yokufaka ngaphandle kwamaphutha futhi isebenzise i-voltage.
Okwamamuva. Ngakho-ke, kungenye yezinkomba ezibalulekile ukukala ukufakwa kwezinto zikagesi, futhi kuyinkomba eyinhloko yomsebenzi wokuphepha womkhiqizo.
Gcina ukuvuza kwamanje ngenani elincane, elidlala indima ebalulekile emsebenzini wokuphepha wemikhiqizo yangaphambili.
Umhloli wamanje wokuvuza ohlelekile usetshenziselwa ukukala okungekho okuvuza akunakuphikwa ekusebenzeni okukhiqizwe ukuhlinzekwa kwamandla okusebenza (noma okunye amandla) okufakwayo kukagesi ngokusebenzisa ukufakwa kogesi noma ukuvinjwa kwalo, kanye nokuvinjwa kwalo kokufaka kulingisa ukungafani komuntu Umzimba.
I-Buvuage Checker yamanje yakhiwa ngokuguqulwa kwe-Imperance, ukuguqulwa kobubanzi, ukuguqulwa kwe-AC-DC, ukunwebeka, okubonisa imibuthano ye-alamu ephezulu yamanje, imishini yokuhlela i-voltage ye-arvinter, kanye nemishini yazo ekhombisa ihlukaniswe Ezinhlotsheni ze-analog kanye ne-digital.
Okubizwa ngokuthi yi-Thinta njengamanje, ngamafuphi, kubhekiswa kokwesamanje okugeleza kwengxenye yensimbi ethinta insiza yomzimba womuntu engxenyeni ephansi noma engxenyeni ethintako. Kulokhu, kufanele sikusebenzise lapho sibheka umjikelezo womzimba womuntu wokulingisa, ukufana kwe-voltmeter, kanye nomjikelezo womuntu wokulingisa umzimba banemibuthano ehlukile yomzimba womuntu ngokusho kwemithetho ephephile yomkhiqizo ngokusho kwemithetho ehlukile yokuphepha komkhiqizo ngokusho kwemithetho ehlukile yokuphepha yomkhiqizo ngokusho kwemithetho yezokuphepha yomkhiqizo.
Kunezinhlobo ezine zokuvuza okukhona manje: Ukuvuza kwe-semiconductor okuvuzayo, ukuvuza kwamandla kwamandla kwamanje, ukuvuza kwe-capacitor kwamanje nokuvuza okuvuza kwamanje.
Igama lesiShayina: ukuvuza kwamanje; Igama Langaphandle: Ukuvuza Kwamanje
1 ukuvuza kwamanje kwezakhi ze-semiconductor
2 Ukuvuza kwamandla kwamuva
3 capacitor ukuvuza kwamanje
4 Hlola ukuvuza kwamanje
1. Ukuvuza kwamanje kwezakhi ze-semiconductor
Ukugeleza okuncane kakhulu kwamanje nge-PN Junction lapho kuvaliwe. Lapho i-DS isethwe ku-snias edlulile futhi i-GS ibuyela emuva, ngemuva kokuthi isiteshi sokuqhutshwa sivuliwe, amanje azogeleza kusuka ku-d to s. DS ukuvuza kwamanje.
2. Amandla okuvuza kwamandla
Ukuze sinciphise ukuphazamiseka ekushintsheni kwamandla okushintsha, ngokuya nge-National Standard, kufanele kufakwe umjikelezo wesihlungi se-EMI. Ngenxa yokuxhumeka kwesifunda se-EMI, kukhona okuncane okukhona emhlabathini ngemuva kokushintshwa kwamandla okushintsha kuxhunywe ekunikezelweni kwamandla, okuwukuvuza kwamanje. Uma kungasisekelo, igobolondo lekhompyutha lizoba namandla kagesi ama-volts angu-110 emhlabathini, futhi lizozizwa lihlangenwe nakho lapho lithintwa ngesandla, okuzothinta nokusebenza kwekhompyutha.
3. I-capacitor ivuza okwamanje
ICapacitor Medium ayinakuba ngcono ngokungazenzisi. Lapho iCapacitor isetshenziswa nge-DC voltage, i-capacitor izoba nokuvuza kwamanje. Uma indawo yokuvuza inkulu kakhulu, i-capacitor izolimala ngokushisa. Ngaphezu kwama-capacitors we-electrolytic, ama-termage avuzayo amanye ama-capacitors amancane kakhulu, ngakho-ke i-parameter yokumelana yokufakelwa isetshenziselwa ukukhombisa umsebenzi wayo wokufakelwa; Futhi i-electrolytic casacitor ine-shizatha enkulu yamanje, ngakho-ke i-aakAge yamanje isetshenziselwa ukukhombisa umsebenzi wayo wokufakelwa (okulingana nomthamo).
Ukusebenzisa i-voltage eyengeziwe yokusebenza kwe-DC eya eCapacitor kuzobona ukuthi ukukhokhisa izinguquko zamanje, bese kuncipha ngokuhamba kwesikhathi. Lapho ifinyelela inani elithile lokugcina, inani lokugcina lentengo lamanje elifinyelela esimweni esizinzile esibizwa ngegama elithi ukuvuza kwamanje.
Okwesine, Ukuvuza Kokuhlamba Kwamanje
Ukuchazwa kokuvuza kwamanje kwesihlungi se-Power Supply: okwamanje kusuka ecaleni lokuhlunga kuya ekugcineni kokuphikisana kwezokuxhumana umugqa ongenayo ngaphansi kwe-voltage eyengeziwe yokuxhumana.
Uma wonke amachweba wesihlungi afakwa ngokuphelele ezindlini, inani lentengo yokuvuza ngokuyinhloko lincike ekuvukeni kwamanje kwe-capacitor evamile ye-copacitor Cy
Ngoba i-Filter Buvuage yamanje ihlobene nokuphepha komuntu siqu, wonke amazwe emhlabeni anemithetho eqinile kuso: Ukuhlinzekwa kwamandla kagesi okuqinile kuso: Ukuhlinzekwa kwamandla kagesi angama-2200 / 50hz
