Daim Ntawv Thov Khoom Siv Hluav Taws Xob 2011.2
4 Cov yam ntxwv ntawm cov hluav taws xob tsis zoo fuses
Hauv ntau qhov xwm txheej, koj tsuas siv tau cov fuses, xws li hluav taws xob semiconductors
Rau kev tiv thaiv ntawm qhov chaw, fuse ceev tseem siv tam sim no. Cov hauv qab no yog qhov feem ntau
Hom gG-hom fuses thiab lawv cov khoom siv hloov khoom siv sib txuam tau siv hauv
Cov tub txawg tswj hwm cov hluav taws xob faib me me los tshawb xyuas qhov zoo ntawm kev fuse
taw tes:
a. Muaj peev xwm tawg siab. NH hom fuse tuaj yeem ncav cuag li 500V
120kA, qhov ntsuas siab tshaj plaws ntawm txhua qhov hluav taws xob qis hluav taws xob,
Tsis muaj suab nrov thiab pom lub zog hauv cov txheej txheem, uas yog, tsis muaj qhov sib txuam;
b. Cov yam ntxwv zoo tam sim no-lim tawm: cov yam ntxwv tam sim no-lim yog cov yam ntxwv tseem ceeb tshaj plaws ntawm fuse
Ib qho ntawm cov ntsiab lus yog tias thaum luv-Circuit Court tam sim no tawg, muaj lub zog muaj zog tam sim no kom tsis txhob raug
Lub cuab yeej hluav taws xob tau txuas dawb los ntawm kev cuam tshuam thiab rhuav tshem ntawm luv luv-Circuit Court tam sim no;
c. Kev xaiv zoo. Tus qauv tsim qauv hluav taws xob tsim qauv thauj khoom tseem ceeb
Sab qaum thiab qis dua cov cuab yeej tiv thaiv yuav tsum xaiv. Thiab ntev li ntev tau tsim tawm los ntawm cov qauv
Qhov ntsuas ntawm qhov ntsuas tam sim no ntawm lub siab thiab qis fuse yog qhov ntau dua 1.6, nws suav tias yog
Txaus siab rau kev xaiv ntawm superior thiab subordinate tiv thaiv cov cuab yeej hluav taws xob, txawm tias lawv tsis yog tib lub lag luam
Cov khoom lag luam tseem tuaj yeem sib ntsib, thiab qee lub tuam txhab cov khoom lag luam muaj ntau dua xaiv
Qeb qib qis dua tuaj yeem ua tiav 1: 1.25, lwm yam khoom lag luam yog qhov nyuaj ua kom tiav.
Ntxiv mus, qhov teeb tsa tam sim no ntawm lub fuse yog txo, thiab tus neeg xyuas pib hla-ntu tuaj yeem txo kom haum raws li.
me me;
d. Kev laus zoo tiv thaiv: tom qab hloov nrog lub fuse tshiab, nws tseem tuaj yeem tuav cov qub
Cov yam ntxwv kab
e. Me me, tsis tshua muaj nqi, hloov tau yooj yim thiab muaj kev ntseeg siab;
f. Txuag peev, txo zog poob ntawm cov ua tiav cov khoom siv, thiab siv fusing
Cov naj npawb ntawm cov ua tiav ntawm cov txee tuaj yeem raug txo kom tsawg.
Coob leej xav tias cov hluav taws xob hluav taws xob qis muaj qhov tsis zoo hauv qab no:
a. Lub fuse yuav tsum tau hloov tom qab lub fuse raug tshuab vim muaj kev txhaum;
b. Txoj haujlwm tiv thaiv yog ib leeg, tsuas yog ib lub sijhawm ntawm dhau tam sim no rov qab siv lub sijhawm txwv
Qhov kev tiv thaiv no siv rau kev sib tshooj, luv Circuit Court thiab hauv av txhaum;
c. Thaum one-phase fusion tshwm sim, nws yuav ua rau kev ua haujlwm tsis zoo ntawm ob-theem
los ntawm;
d. Tsis muaj kev sib txuas lus muaj nuj nqi, tsis tuaj yeem ua tiav kev txawj ntse.
Hais txog qhov luv luv a, qhov no tsis yog qhov luv. Thaum kab yog kev saib xyuas
Tom qab cov khoom tiv thaiv tau raug txiav tawm, nws qhia tau tias muaj kev txhaum. Yog tias tsis muaj kev lees paub, koj tuaj yeem tshawb xyuas cov cuab yeej
Ua ntej Circuit Court muaj kev nyab xeeb rau kev tiv thaiv, tsis pub rov txuas rau hauv Circuit Court
Raug tsim txiaj. Txawm li cas los xij, lub sijhawm no, lub fuse tuaj yeem hloov lossis kho
Lub Circuit Court breaker recloses nyob rau hauv parallel, tab sis tus naj npawb ntawm luv Circuit Court tawg lub sij hawm ntawm Circuit Court breaker yog tsawg
, Feem ntau nws tsis tuaj yeem kuaj xyuas nws cov xwm txheej sab hauv.
Rau qhov ua tsis tiav c thiab d, yog tias fuse nrog lub suab ceeb toom raug siv,
Lossis nws daws tau los ntawm kev siv lub fuse-hom cais mus. Xob
Lub tuam txhab cov khoom lag luam nkag hauv Suav teb thaum pib xyoo 1990 tau daws teeb meem
Qhov tsis muaj sijhawm ua haujlwm ntawm lub fuse; thiab tam sim no ntau ntawm cov khoom siv muaj peev xwm ntau dua
Hloov kho qhov hloov mus rau qhov siab dua thiab siab dua" kev txawj ntse" yuav tsum, xws li
Tswj lub kaw lus lossis tshuaj xyuas cov kev sib tham. Ntxiv nrog rau qhov tam sim no transformer thiab
Ntxiv rau lub ammeter, nruab ib lub fuse nrog tus ntaus nrig thiab lub micro hloov
Tawm, nws tuaj yeem teeb pom kev tawg ntawm lub fuse. Ib yam li ntawd, nrog lub micro txav
Nws tseem tuaj yeem tso cov lus qhib thiab kaw ntawm lub fuse load cais tawm mus.
Los ntawm cov cheebtsam no,
NH fuse hloov tau yooj yim txuas nrog SPS thiab chaw tos tsheb loj
Cov cuab yeej niaj hnub no ntawm cov kab ke tau txuas rau hauv lub network. Txawm tias txoj kev luv luv b los ntawm nws
Nws ntsuas nws kuj tuaj yeem them taus.
Yog tias hluav taws xob siv hluav taws xob tsawg tsis muaj ntau yam zoo, Socomec thiab lwm lub tebchaws
Vim li cas cov tuam txhab txawv teb chaws nquag txhawb nqa kev muag khoom thiab txawm tsim cov chaw tsim khoom hauv kuv lub teb chaws? uas yog
Schneider, uas tau txhim kho feem ntau cov hluav taws xob hluav taws xob hluav taws xob hluav taws xob hauv Tuam Tshoj rau lub sijhawm ntev, kuj yog
Lub fuse cais tawm hluav taws xob tau pib thaum kawg ntawm 2007, tsis yog nws tsim nyog?
Xav? Qhov tseeb, nws tseem tsis tau nrhiav tau txhua-txhua-txhua
Txawv rau kev fuses. 5 Xaus
Ntawm no, lub fuse tsis tau qhuas thiab lub Circuit Court breaker raug cais tawm, tsis yooj yim
Nyob rau hauv lwm yam lus, fuses thiab Circuit Court tej fais fab yog tseeb txawv ntawm cov yam ntxwv khoom.
Muaj ntau qhov zoo thiab qhov tsis zoo nyob rau hauv ntau daim ntawv thov. Xaiv qhov yog
Muaj peev xwm txhim kho kev txuag hluav taws xob thiab txhim kho kev nyab xeeb ntawm cov khoom hluav taws xob.
