Lub 630A High Current -Kev Ua Tau Zoo Li Cas? Qhia Yuav Ua Li Cas 25kV 25kV Load Switches Design Principles

Nyob rau hauv lub hwj chim system, load switches, raws li cov khoom tseem ceeb, yuav siv sij hawm qhov tseem ceeb ntawm kev kaw, nqa, cuam tshuam ib txwm los yog overload tam sim no. Tshwj xeeb tshaj yog nyob rau hauv high-voltage hluav taws xob teb nrog 25kV voltage voltage, tus tsim ntawm load keyboards yuav tsum tsis tsuas yog ua tau raws li qhov yuav tsum tau ntawm loj tam sim no nqa peev xwm, tab sis kuj ua kom muaj kev ruaj ntseg thiab ruaj khov ua hauj lwm nyob rau hauv complex kab sib chaws. Nyob rau hauv daim ntawv no, qhov kev siv ntawm 630A siab tam sim no - nqa lub peev xwm hloov yuav tau kawm tob, qhia txog tus qauv tsim ntawm 25kV load switches.
Ua kom tiav 630A High Current -Tsev Muaj Peev Xwm
1.Kev xaiv cov khoom siv thiab cov qauv tsim
Thawj qhov yuav tsum tau ua ua ntej kom ua tiav 630A siab tam sim no - nqa lub peev xwm yog xaiv cov khoom siv hluav taws xob zoo heev. Tooj liab muaj qhov zoo conductivity thiab txhua yam khoom thiab yog cov khoom siv zoo tshaj plaws rau kev tsim cov khoom siv hluav taws xob hloov hluav taws xob. Piv txwv li, siab - cov khoom siv tooj liab purity yog siv rau hauv kev tsim cov ntsiab lus sib txuas rau cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob, thiab cov txheej txheem tshwj xeeb xws li nyiaj plating yog siv los txhim kho hluav taws xob conductivity thiab corrosion kuj.
Nyob rau hauv cov nqe lus ntawm tus qauv tsim, load switches txais modularized tsim qauv, uas yog yooj yim rau kev sib txuas thiab nthuav flexibly raws li qhov xav tau tiag tiag. Piv txwv li, CMW series 630A siab- fais fab connectors, tsim nws tus kheej los ntawm Tengfang Zhongke, muaj ib tug compact modular installation tsim. Qhov no tsis yog tsuas yog txhim kho qhov chaw siv xwb tab sis kuj tseem txhim kho cov neeg kho tshuab lub zog, ua kom muaj kev sib txuas ruaj khov txawm tias nyob rau hauv cov xwm txheej hnyav xws li kev thauj khoom siab thiab kev co.
2.Application ntawm arc extinguishing tshuab
Ib qho arc tshwm sim thaum lub load hloov cuam tshuam rau tam sim no. Yog tias tsis tua nyob rau lub sijhawm, kev puas tsuaj loj yuav ua rau cov khoom siv. Yog li ntawd, arc extinguishing thev naus laus zis yog qhov tseem ceeb kom paub txog lub peev xwm nqa ntawm cov tam sim no loj. Cov txheej txheem arc extinguishing yog pneumatic arc extinguishing SF6 gas arc extinguishing thiab nqus arc extinguishing.
Pneumatic Arc-Kev tua: Txoj kev no siv cov pistons los compressed cua thiab dav hlau ntawm compressed cua kom tshuab tawm arc. Cov qauv yooj yim, haum rau 35 kV thiab hauv qab no.
SF6 Gas Arc-Kev tua: SF6 roj muaj qhov hluav taws xob siab thiab kev tua hluav taws, uas tuaj yeem ua tiav qhov cuam tshuam loj tam sim no. Sulfur hexafluoride gas arc extinguishing muaj qhov zoo ntawm qhov muaj peev xwm cuam tshuam tam sim no thiab kev ua haujlwm zoo, tab sis cov qauv yog qhov nyuaj thiab tsim nyog rau siab -voltage arc extinguishing.
Nqus Arc-Kev tua: Hauv lub tshuab nqus tsev, arc tuaj yeem tawg ions sai sai thiab ua rau arc tua sai. Lub tshuab nqus tsev arc extinguishing yog tus cwj pwm los ntawm lub neej hluav taws xob ntev thiab kev saib xyuas tsawg. Dav siv nyob rau hauv 220kV thiab qis dua voltage theem.
3.Heat Dissipation thiab kub tswj
Thaum cov hluav taws xob muaj zog dhau mus, lub cuab yeej tsim hluav taws xob ntau. Yog hais tias nws tsis dissipate nyob rau hauv lub sij hawm, nws muaj peev xwm ua rau kom kub heev nce thiab cuam tshuam rau kev ua tau zoo thiab kev pab cuam lub neej. Yog li ntawd, kev tsim hluav taws kub dissipation yog ib qho tseem ceeb kom paub txog kev muaj peev xwm nqa tau siab.
Load switches siv aaa ntau yam kev ntsuas kub dissipation, xws li ua kom sov lub dab dej, optimizing cua duct tsim thiab siv cov ntaub ntawv uas muaj thermal conductivity. Piv txwv li, hauv PCB tsim, ua kom cov tuab ntawm tooj liab, nthuav dav cov kab dav dav thiab ua kom sov dissipation ntawm PCB tuaj yeem txo qhov kub thiab txias thiab ua kom ruaj khov nyob rau hauv siab tam sim no.
Qhia tawm yuav ua li cas 25kV 25kV Load Switches Design Principles
1.Arc-Tswj Chamber Design
Lub arc chamber tsim yog cov tseem ceeb ntawm 25kV load hloov. Lub arc extinguishing chamber yog tsim los ntawm cov ntaub ntawv tshwj xeeb thiab muaj cov khoom zoo insulating thiab arc extinguishing muaj peev xwm. cua dav hlau los yog SF6 roj yuav siv tau los tshuab tawm lub arc extinguishing chamber thaum qhib los tiv thaiv arc reignition thiab khoom puas.
2.Kev tsim cov txheej txheem ua haujlwm
Tus tsim ntawm kev ua haujlwm mechanism ntawm kev hloov pauv ncaj qha cuam tshuam rau qhov qhib thiab kaw nrawm thiab kev ntseeg tau ntawm kev hloov. Ib qho 25kV load hloov feem ntau suav nrog lub caij nplooj ntoos hlav -loaded mechanism uas khaws lub zog los ntawm lub tshuab hluav taws xob lossis manually qhib thiab kaw sai. Lub tshuab ua haujlwm kuj tseem muaj cov cuab yeej sib cuam tshuam los tiv thaiv kev ua haujlwm tsis zoo thiab ua kom muaj kev nyab xeeb ntawm cov khoom siv.
3.Insulation thiab kev tiv thaiv tsim
Hauv qhov chaw siab -voltage, kev ua haujlwm rwb thaiv tsev yog qhov tseem ceeb tshaj plaws. Lub 25kV load hloov siv siab -cov ntaub ntawv muaj zog xws li epoxy resin thiab silicone los xyuas kom meej rwb thaiv tsev ua haujlwm nyob rau hauv ib puag ncig hnyav. Tsis tas li ntawd, cov cuab yeej tau nruab nrog cov cuab yeej tiv thaiv zoo xws li cov ntaub npog los nag thiab plua plav npog kom tsis txhob muaj kev puas tsuaj los ntawm lwm yam.
4.Kev txawj ntse thiab kev tswj chaw taws teeb
Nrog rau txoj kev loj hlob ntawm daim phiaj ntse, kev txawj ntse thiab kev tswj chaw taws teeb ntawm cov khoom siv hluav taws xob tau dhau los ua ib qho qauv. Los ntawm kev sib koom ua ke ntse sensors thiab kev sib txuas lus modules, 25kV load hloov tuaj yeem saib xyuas cov khoom siv hauv lub sijhawm tiag tiag thiab tswj tau nyob deb. Qhov no tsis tsuas yog txhim kho kev ua haujlwm ntawm cov cuab yeej siv, tab sis kuj tseem txhim kho kev nyab xeeb thiab kev ntseeg siab ntawm daim phiaj hluav taws xob.
