Ucweyo lwangaphambili
Asinalo kuphela inani loomatshini bemveliso abazenzekelayo kunye noomatshini bovavanyo oluzenzekelayo kodwa sinelabhoratri yethu yokuvavanya ukusebenza kunye nokuthembeka kweemveliso zethu.
1. Uthini umahluko phakathi kwee-capacitors zokhuseleko kunye nee-capacitors eziqhelekileyo?
Ukukhutshwa kwee-capacitors zokhuseleko kuyahluke kwi-capacitors eqhelekileyo.Ii-capacitors eziqhelekileyo ziya kugcina umrhumo ixesha elide emva kokuba umbane wangaphandle unqanyuliwe.Ukothuka kombane kunokwenzeka ukuba umntu ubambe i-capacitor eqhelekileyo ngesandla, ngelixa kungekho ngxaki malunga neecapacitors zokhuseleko.
Ukhuseleko kunye ne-Electro Magnetic Compatibility (ingqwalasela ye-EMC), ngokuqhelekileyo kucetyiswa ukuba ungeze i-capacitors yokhuseleko kwi-inlet yamandla.Ekupheleni kokufakwa kombane we-AC, ngokuqhelekileyo kuyimfuneko yokongeza i-3 capacitors yokhuseleko ukucinezela ukuphazamiseka kwe-EMI.Zisetyenziswa kwisihluzo sonikezelo lwamandla ukuhluza unikezelo lwamandla.
2. Yintoni i-capacitor yokhuseleko?
I-capacitors yokhuseleko isetyenziswe kwiimeko ezinjalo emva kokuba i-capacitor ingaphumeleli: ayiyi kubangela ukutshitshiswa kombane kwaye ayiyi kubeka engozini ukhuseleko lomntu.Iquka i-X capacitors kunye ne-Y capacitors.I-x capacitor yi-capacitor edityaniswe phakathi kwemigca emibini yombane wamandla (LN), kunye ne-metal film capacitors zisetyenziswa ngokubanzi;i-Y capacitor yi-capacitor edibeneyo phakathi kwemigca emibini yomgca wamandla kunye nomhlaba (LE, NE), kwaye ngokuqhelekileyo ibonakala ngababini.Ngenxa yokunciphisa ukuvuza kwangoku, ixabiso le-Y capacitor alikwazi ukuba likhulu kakhulu.Ngokubanzi, i-X capacitor yi-uF kunye ne-Y capacitor yi-nF.I-X capacitor icinezela ukuphazamiseka kwemodi yokwahlukana, kwaye i-Y capacitor icinezela ukuphazamiseka kwemowudi eqhelekileyo.
3. Kutheni ezinye ii-capacitors zibizwa ngokuba zii-safety capacitors?
"Ukhuseleko" kwii-capacitors zokhuseleko alubhekiseli kwizinto ze-capacitor, kodwa ukuba i-capacitor iphumelele isatifikethi sokhuseleko;ngokubhekiselele kwizinto eziphathekayo, i-capacitors yokhuseleko ikakhulu i-CBB capacitors kunye ne-ceramic capacitors.
4. Zingaphi iindidi zee-capacitors zokhuseleko ezikhoyo?
Ii-capacitors zokhuseleko zahlulwe ngohlobo lwe-X kunye nohlobo lwe-Y.
Ii-X capacitors zisebenzisa ii-polyester film capacitors ezinemisinga emikhulu.Olu hlobo lwe-capacitor lunomthamo omkhulu, kodwa ukutshaja okuvumelekileyo kwangoko kunye nokukhupha okwangoku kukhulu, kwaye ukuchasana kwayo kwangaphakathi kuncinci ngokuhambelanayo.
I-capacitance ye-Y capacitor kufuneka ilinganiselwe, ukwenzela ukuba kufezekiswe injongo yokulawula ukuvuza kwangoku okuhamba kuyo kunye nefuthe ekusebenzeni kwe-EMC kwenkqubo phantsi kwe-frequency elinganisiweyo kunye ne-voltage elinganisiweyo.I-GJB151 imisela ukuba amandla e-Y capacitor akufanele abe mkhulu kuno-0.1uF.
