Dab tsi yog qhov txawv ntawm kev ntsuas kev nyab xeeb capacitor thiab cov capacitors li niaj zaus?

1. Kev tso tawm ntawm kev nyab xeeb-gauge capacitor tsis zoo ib yam li cov capacitors zoo tib yam

Cov khoom siv hluav taws xob zoo tib yam yuav khaws lawv cov nqi ntev ntev tom qab cov khoom siv hluav taws xob sab nraud raug txiav, thiab yog tias koj kov lawv nrog koj txhais tes, koj yuav raug hluav taws xob. Thaum lub ntsuas kev nyab xeeb capacitors tsis muaj qhov teeb meem no, kev ntsuas kev nyab xeeb capacitors tsis ua haujlwm, yuav tsis ua rau hluav taws xob poob siab, tsis ua rau muaj kev nyab xeeb ntawm tus kheej.
Kev nyab xeeb capacitor suav nrog X thiab Y capacitor.
Ntawm AC lub zog hluav taws xob, feem ntau peb yuav tsum muaj kev ruaj ntseg ntxiv rau EMI kev cuam tshuam.
Lub x- capacitor yog lub capacitor txuas hla lub hwj chim kab ntawm ob kab (L-N), feem ntau xaiv hlau zaj duab xis capacitors; Y- capacitor yog lub capacitor txuas nrog hla cov kab hluav taws xob nruab nrab ntawm ob kab thiab hauv av (L-E, N-E) feem, feem ntau tshwm sim ua khub. Raws li kev txwv tam sim no, Y capacitance tus nqi tsis tuaj yeem loj dhau, feem ntau X capacitance yog uF qib, Y capacitance yog nF qib. X capacitance suppresses txawv hom cuam tshuam, Y capacitance suppresses hom kev cuam tshuam.

Y capacitor txuas nrog lub capacitor ntawm hluav taws xob hlau (L) thiab av xaim (E) thiab nruab nrab ntawm xoom xaim (N) thiab hauv av xaim (E).Y lub capacitor kev sib txuas txoj haujlwm tseem ceeb heev, thiab yuav tsum ua raws li cov qauv kev nyab xeeb uas cuam tshuam los tiv thaiv cov khoom xau los ntawm cov khoom siv lossis cov casing raug them rau kev nyab xeeb ntawm tus kheej. Feem ntau nyob rau hauv lub subtropical tshuab yuav tsum tau rau hauv av to tam sim no tsis tau tshaj 0.7mA, nyob rau hauv lub temperate cheeb tsam ntawm lub tshuab yuav tsum tau rau hauv av to tam sim no tsis tau tshaj 0.35mA. Yog li ntawd, tag nrho lub peev xwm ntawm Y capacitor tsis tuaj yeem tshaj 4700pF (472).

2.Qhov txawv ntawm kev nyab xeeb-gauge capacitor thiab cov khoom siv hluav taws xob zoo tib yam
1.Certification txawv.
Ordinary CBB capacitors, nws tsis xav tau ntawv pov thawj, tab sis kev ruaj ntseg capacitors feem ntau yuav tsum tau mus dhau ntau daim ntawv pov thawj, xws li CQC, VDE, UL, CUL, thiab lwm yam, thiab ntau daim ntawv pov thawj zoo dua.
2, kev ruaj ntseg capacitors yog feem ntau rau X capacitor thiab Y capacitors

X capacitors rau kev tawm tsam ntawm kev sib txawv ntawm kev cuam tshuam, feem ntau hla kev sib txuas ntawm L thiab N (N sawv cev ntawm xoom kab, L sawv cev ntawm cov hluav taws xob), qhov ntau yog X1 capacitors thiab X2 capacitors. Txhua qib muaj qhov sib txawv tiv taus voltage. Kev ua tsis tiav yuav tsis muaj teeb meem.
Kev nyab xeeb Y capacitors yog subdivided rau hauv Y1 capacitors thiab Y2 capacitors, txhawm rau tiv thaiv kev cuam tshuam ntau yam, Y capacitors yog kev nyab xeeb series capacitors, capacitors txuas nrog nyob rau hauv parallel ntawm hluav taws xob xaim thiab hauv av xaim nrog rau nruab nrab ntawm xoom xaim thiab hauv av xaim raug xa mus ua Y capacitors. Feem ntau yuav muaj cov dej xau tam sim no.
Kev nyab xeeb capacitors yog siv rau hauv cov khoom siv hluav taws xob hluav taws xob thiab cov khoom siv hluav taws xob, siv rau cov keyboards, kev sib cuag thiab lwm qhov chaw ntawm lub txim hluav taws xob, tuaj yeem ua lub luag haujlwm hauv kev nqus cov mem tes cuam tshuam thiab txo cov hluav taws xob tsis zoo.
CBB capacitors yog dav siv nyob rau hauv txhua yam ntawm cov khoom siv hluav taws xob, lub cev muaj zog sib txawv, cov cuab yeej hluav taws xob, cov khoom siv teeb pom kev zoo, lub tshuab cua txias, tub yees, tshuab ntxhua khaub ncaws thiab lwm yam khoom siv hauv tsev, nrog rau cov tshuab hluav taws xob.

3, txawv qhov tsos.

Zoo li X chav kawm kev nyab xeeb capacitors, feem ntau ntsia hauv lub plhaub yas, CBB capacitors zoo tib yam, feem ntau yog epoxy resin encapsulated.

4, tus nqi sib txawv.

Tib lub peev xwm, tib lub zog, kev ruaj ntseg capacitors kuj tseem kim dua, vim tias cov capacitors no yuav tsum tau siv ntau cov ntawv pov thawj cov nqi txhua xyoo, thiab cov txheej txheem ntau lawm kuj txawv.
