Yuav ua li cas kom txo cov inrush tam sim no ntawm kev voltage qis qis dua tshiab tshaj tawm?

Raws li tus xa khoom ntawm kev siv hluav taws xob qis dua tshiab series, Kuv nkag siab qhov tseem ceeb ntawm kev txo qis hauv cov tshuab hluav taws xob. Inrush tam sim no yog thawj zaug siab tam sim no uas ntws mus rau hauv cov khoom hluav taws xob thaum nws tau qhib. Qhov kev kub siab no tuaj yeem ua rau muaj cov teeb meem ntau yam, xws li kev puas tsuaj rau lub cuab yeej, ntxaij kev sib tw, thiab cuam tshuam nrog lwm cov khoom siv hluav taws xob. Hauv no blog ncej, Kuv yuav sib tham txog ntau txoj hauv kev los txo cov inrush tam sim no ntawm kev voltage qis dua tshiab series.

Nkag siab inrush tam sim no

Ua ntej delving rau hauv cov kev daws teeb meem, nws yog qhov tseem ceeb kom nkag siab txog cov laj thawj ntawm inrush tam sim no. Nyob rau hauv lub voltage qis dua transser series, inrush tam sim no tshwm sim vim muaj kev them nyiaj ntawm capacitors thiab kev sib nqus ntawm inductive Cheebtsam. Thaum lub tshuab hloov yog kaw, capacitors kos cov nyiaj ntau ntawm cov nqi tam sim no tam sim no mus txog lub kaw lus hluav taws xob. Ib yam li ntawd, inductive Cheebtsam, xws li transformers thiab cov tshuab raj, xav tau qhov pib siab tam sim no los tsim cov tshav sib nqus.

 

 

Cov hau kev los txo cov inrush tam sim no

1. Mos-Pib Li

Mos-pib cov khoom siv yog ib txoj hauv kev zoo los txo qis hauv qhov tam sim no. Cov khoom siv no maj mam hloov cov hluav taws xob siv rau lub thauj khoom, tso cai rau cov khoom siv capacitors kom tau them qeeb thiab cov khoom siv inductive kom mus txog lawv lub xeev ua haujlwm. Los ntawm kev tswj hwm tus nqi ntawm voltage nce, cov khoom siv mos-pib tuaj yeem txo qis hauv lub plab tam sim no.

Muaj ntau hom khoom muag-pib muaj, suav nrog SCRESS-State Stanters thiab autotransformer muag muag pib. Tau-lub xeev cov khoom muag pib siv cov tub ntxhais los tswj cov hluav taws xob siv rau lub nra. Lawv muab cov kev tswj kom meej thiab tuaj yeem yooj yim sib xyaw ua ke rau hauv qhov chaw voltage qis dua tshiab tshaj tawm. Autotransformer mos pib, ntawm qhov tod tes, siv lub autotransflication kom txo qhov hluav taws xob thaum pib lub sijhawm. Lawv haum rau cov kev siv hluav taws xob siab thiab tuaj yeem muab qhov pib du.

2. Inrush cov kev txwv tam sim no

Inrush cov kev txwv tam sim no yog cov khoom ua haujlwm dhau los uas tuaj yeem siv los txwv qhov nyob hauv qhov tseem ceeb tam sim no. Cov cuab yeej siv no yog ib txwm ua los ntawm lub thermistor lossis qhov ntsuas kub thiab txias (PTC) resistor. Thaum tus hloov pauv raug kaw, lub inrush tam sim no tsis muaj lub siab tiv, uas txwv qhov pib ntws tam sim no. Raws li cov txheej txheem tam sim no los ntawm cov txwv, nws qhov kub nce, ua rau nws txoj kev tiv taus tsawg dua kom tsawg dua. Thaum cov cuab yeej mus txog nws kev ua haujlwm kub, qhov tsis kam ntawm cov inrush tam sim no unlimiter yog tsawg txaus kom cia cov ntws tam sim no.

Inrush cov kev txwv tam sim no yooj yim thiab cov kev daws teeb meem zoo rau kev txo qis hauv qhov tam sim no. Lawv tuaj yeem tau yooj yim nyob rau hauv lub voltage qis dua hloov tshiab series thiab tsis tas yuav muaj ib qho kev tswj hwm sab nraud. Txawm li cas los xij, lawv muaj qhov muaj peev xwm siv sijhawm tam sim no thiab yuav tau hloov chaw yog tias lawv raug cov khoom tsis tu ncua.

3. Ua Ntej-Them Tsheb

Ua ntej-them hluav taws xob yog lwm txoj kev los txo qhov tam sim no tam sim no. Cov kev sib tw no siv tus neeg tiv thaiv me lossis cov khoom siv tam sim no los ua ntej lub capacitors ua ntej lub tshuab hloov loj kaw. Los ntawm kev them se-them lub capacitors, lub hauv qab tam sim no tuaj yeem txo qis.

Pre-them hluav taws xob tuaj yeem ua tiav siv ntau yam ntawm cov cheebtsam, xws li resistors, diodes, thiab relays. Cov txheej txheem them ua ntej tuaj yeem tswj hwm manually los yog cia li siv lub sijhawm lossis lub ntsuas hluav taws xob. Thaum lub peev xwm puv tau raug them tag nrho, lub ntsiab hloov tuaj yeem kaw, thiab qhov kev ntws tawm tam sim no tuaj yeem rov pib dua.

4. Lub Zog Kev Kho Mob

Muaj peev xwm kho tau lub hwj chim (PFC) kuj tseem tuaj yeem pab txo kom muaj nyob rau hauv tam sim no. PFC yog cov txheej txheem siv los txhim kho lub zog siv hluav taws xob ntawm cov hluav taws xob los ntawm kev txo cov hwj huam. Los ntawm kev txo cov hwj huam ua kom muaj zog, lub zog hluav taws xob ntawm lub system yog tsawg dua, uas nyob rau hauv lem txo cov inrush tam sim no.

Muaj ob hom ntawm PFC: Passive PFC thiab Active PFC. Passive PFC siv inductors thiab capacitors los kho lub hwj chim siv lub zog. Nws yog qhov kev daws teeb meem yooj yim thiab muaj txiaj ntsig tab sis muaj kev ua tau zoo. Nquag PFC, ntawm qhov tod tes, siv hloov pauv hloov kho kom tswj tau lub hwj chim. Nws muab kev ua haujlwm siab dua thiab ua tau zoo dua tab sis yog cov nyom ntau dua thiab kim.

Daim Ntawv Thov nyob rau hauv tsis tshua muaj voltage transser series

Ntawm peb lub tuam txhab, peb muab ntau yam ntawm cov voltage qis qis dua xa tawm cov khoom lag luam, suav nrog covJXF Tsawg Voltage Txuas Lub Zog Hluav Taws Xob, tusJP Sab Nraum Ze Tawm Hluav Taws Xob Hluav Taws Xob, thiab tusGCK tsawg voltage rho tawm lub zog hloov lub thawvCov. Cov khoom no tau tsim los ua kom tau raws li cov kev xav tau ntawm peb cov neeg muas zaub thiab tau nruab nrog cov yam ntxwv siab tshaj plaws kom txo qis hauv qhov tam sim no.

Piv txwv li, peb JXF tsawg voltage sib xyaw fais fab lub thawv yog nruab nrog cov khoom siv mos-pib kom ntseeg tau tias qhov pib tam sim no. JP Sab nraum zoov Chaw Muag Hluav Taws Xob Hluav Taws Xob Siv Hluav Taws Xob siv los tiv thaiv cov khoom siv los ntawm cov hauv siab inrush. Lub GCK tsawg voltage rho tawm lub zog hloov lub thawv thiab lub zog txhim kho kev ua kom zoo rau kev ua haujlwm ntawm cov kab ke thiab txo cov inrush tam sim no.
