Qhov tseem ceeb ntawm instantaneous overcurrent tiv thaiv
Instantaneous overcurrent tiv thaiv yog ib qho tseem ceeb tshaj plaws thiab tseem ceeb tam sim no txoj kev tiv thaiv hauv lub zog hluav taws xob. Nws cov yam ntxwv tseem ceeb yog: nrawm nrawm thiab tsis ncua sijhawm.
Kev ua haujlwm ntawm instantaneous overcurrent tiv thaiv: Nyob rau hauv cov xwm txheej ntawm ib tug luv luv Circuit Court, nws disconnects lub Circuit Court kom sai li sai tau los tiv thaiv cov khoom thiab cov neeg ua hauj lwm. Yog tsis muaj kev tiv thaiv overcurrent tam sim no, 8000A tam sim no kav ntev li 0.5 vib nas this yuav hlawv tawm ib lub cable.
Lub hauv paus ntsiab lus kev khiav hauj lwm ntawm instantaneous overcurrent tiv thaiv=Tiag - lub sij hawm tam sim no saib xyuas → Thaum lub sij hawm teem nqi tshaj → Direct tripping tsis ncua
Vim li cas thiaj xav tau kev tiv thaiv overcurrent instantaneous?
1- Tiv thaiv cov cuab yeej los ntawm burnout
Yog tias tsis txuas sai sai, cables yuav yaj nyob rau hauv vib nas this, thiab transformers / generators yuav raug txo kom seem hlau.
2- Tiv thaiv kom tsis txhob muaj xwm txheej ntau ntxiv
Yog tias qhov luv luv Circuit Court tsis raug txiav rau lub sijhawm, nws yuav cuam tshuam rau cov khoom siv hluav taws xob
Tej zaum yuav ua rau cascading tripping → Fais fab tuag ntawm tag nrho cov busbar → Loj - teev fais fab tuag
Instantaneous overcurrent tiv thaiv txwv qhov txhaum mus rau qhov tsawg kawg nkaus
3- Ua kom muaj kev nyab xeeb ntawm tus kheej
Instantaneous overcurrent tiv thaiv mus ncig ua ntej muaj kev phom sij tshwm sim, txo kev pheej hmoo ntawm kev raug mob.
Vim Li Cas Xaiv Peb
XDTZ lub tshuab nqus tsev vacuum breakers muaj lub sijhawm ua haujlwm tsawg dua 50 milliseconds, ua kom tiav cov khoom siv tiv thaiv relay kom ua tiav kev tiv thaiv overcurrent instantaneous. "Raws li ntev raws li cov cuab yeej tiv thaiv xa cov teeb liab, lub Circuit Court breaker tuaj yeem cuam tshuam qhov txhaum tam sim no."
"XDTZ lub tshuab nqus tsev vacuum breakers muaj cov lus teb ceev ceev thiab tuaj yeem koom tes nrog kev tiv thaiv relay kom ua tiav kev ua haujlwm sai sai."
Ntawm no yog peb lub tshuab nqus tsev vacuum tshwj xeeb rau kev khawb hauv av
VTZ-12GD-MTLub tshuab nqus tsev Circuit Court breaker ua ke cov khoom siv hluav taws xob yog lub tshuab nqus tsev tshwj xeeb rau kev ua haujlwm hauv av nrog cov ntsuas hluav taws xob ntawm 12kV thiab AC 50 / 60Hz.
Nws txais cov hlau nplaum ruaj khov mechanism thiab muaj cov tshuab kaw lus kaw thiab qhib lub zog.
Nws yog qhov tsim nyog rau ntau qhov chaw nrog tawg - cov ntaub ntawv pov thawj rau cov chaw siv hluav taws xob.
Chav tsev trolley yog siv ua ke nrog PJG9-10 hloov txee.
