Kev nyab xeeb kev npaj:
Thaum rub tawm qhov fuse hom poob, tus neeg teb xov tooj yuav tsum siv cov hlua rwb thaiv tsev nrog qhov ntsuas hluav taws xob tsim nyog thiab dhau qhov kev xeem, hnav khau rwb thaiv tsev, hnab looj tes rwb thaiv tsev, lub hau thaiv thiab tsom iav, lossis sawv ntsug ntawm lub platform ntoo qhuav, thiab raug saib xyuas los tiv thaiv tus kheej kev nyab xeeb
Sau ntawv:
Thaum tus neeg teb xov tooj pib lossis xaus qhov rub lossis kaw qhov fuse, yuav tsum tsis muaj kev cuam tshuam.Qhov kev cuam tshuam yuav ua rau lub fuse puas tsuaj, xws li rub thiab tsoo lub insulator, deflecting tus nqi os, rub thiab rhuav lub nplhaib ua haujlwm, thiab lwm yam. yuav tsum tsis txhob siv lub zog ntau dhau thaum lub sijhawm ua haujlwm ntawm hom poob fuse, yog li txhawm rau zam kev puas tsuaj rau lub fuse, thiab kev sib cais thiab kaw yuav tsum nyob hauv qhov chaw.
Cov txheej txheem quab yuam ntawm lub fuse qeeb (pib)- nrawm (thaum txav kev sib cuag nyob ze ntawm qhov sib tiv tauj zoo li qub)- qeeb (thaum kev sib chwv txav mus ze qhov kawg ntawm kev kaw) .Qhov txheej txheem rub lub fuse qeeb (pib) - nrawm (thaum kev txav mus los ze rau qhov sib tiv tauj zoo li qub)- qeeb (thaum qhov sib chwv txav mus ze qhov kawg ntawm qhov rub) .Fast yog txhawm rau tiv thaiv hluav taws xob luv Circuit Court thiab hlawv kev sib cuag los ntawm arc, qeeb yog txhawm rau tiv thaiv kev ua haujlwm ntawm cuam tshuam lub zog, ua rau cov khoom puas rau lub fuse.
Xa qhov kev txiav txim
Qhov ua ntu zus ntawm kev ua haujlwm txhawm rau nres lub zog hluav taws xob ntawm lub tshuab hluav taws xob xa hluav taws xob yog raws li hauv qab no: Raws li qhov xwm txheej ib txwm muaj, qhov hloov hluav taws xob qis ntawm sab nraub qaum yuav tsum tau rub ua ntej, thiab tom qab ntawd qhov hluav taws xob poob qis fuse ntawm lub zog sab yuav tsum tau rub.
Yog tias muaj ntau lub zog siv, raws li cov lus qhia saum toj no ntawm lub zog hluav taws xob, tuaj yeem tiv thaiv kev hloov pauv rov qab, thaum ua tsis tiav, kev tiv thaiv yuav tsis kam txav mus, ncua lub sijhawm tshem tawm qhov ua txhaum, ua kom nthuav dav. Los ntawm lub zog hluav taws xob tuaj yeem txo qhov cuam tshuam pib tam sim no (thauj khoom), txo qhov hloov pauv ntawm qhov hluav taws xob, thiab xyuas kom muaj kev nyab xeeb ntawm cov cuab yeej siv. mus rau lub zog ntau hauv Hauv qhov xwm txheej ntawm lub zog tsis ua haujlwm, nres lub nra ua ntej. Hauv kev ua haujlwm ntawm lub zog tsis ua tiav ib qib zuj zus los ntawm qhov hluav taws xob qis rau qhov hluav taws xob siab, qhov hloov pauv tuaj yeem zam kev txiav tawm cov dej ntws loj tam sim no thiab txo qis thiab qhov ntau ntawm kev ua haujlwm dhau qhov hluav taws xob.
Hauv kev ua haujlwm, sim kom tsis txhob rub thiab poob fuses nrog thauj khoom. Yog tias pom tias cov fuses nrog thauj khoom tau ua haujlwm tsis raug thaum lub sijhawm ua haujlwm, txawm tias cov fuses raug teeb tsa tsis raug lossis txawm tias muaj qhov tshwm sim tshwm sim, nws tsis raug tso cai qhib lub fuse dua.Yog qhov rub tsis raug fuse nrog thauj khoom tshwm sim, thaum txav mus tawm qhov kev sib cuag ruaj khov, ib qho arc yuav tshwm sim. Lub sijhawm no, nws yuav tsum raug kaw tam sim kom tshem tawm cov arc thiab zam kev nthuav dav ntawm qhov kev huam yuaj. ntawm 200 kva lossis tsawg dua, cov fuses ntawm sab qhov hluav taws xob siab tau tso cai cais thiab sib xyaw ua ke tam sim no.
Kev ua haujlwm ib ntu
Peb theem ua haujlwm ib theem zuj zus ntawm qhov hluav taws xob poob qis.
Lub zog tsis ua haujlwm, yuav tsum xub rub theem nrab, tom qab rub ob sab ntawm theem.
Qhov laj thawj tseem ceeb rau kev rub nruab nrab theem ua ntej yog xav txog tias tam sim no thaum theem nruab nrab raug txiav tawm tsawg dua theem sab (ib feem ntawm kev thauj khoom hauv Circuit yog nqa los ntawm ob theem), yog li cov arc me me, thiab tsis muaj kev phom sij rau ob sab ntawm theem.Thaum theem thib ob (theem theem) poob hom fuse tau ua haujlwm, tam sim no loj dua, thaum theem nruab nrab tau rub qhib, thiab lwm ob qhov poob hom fuse yog nyob deb los ntawm ib leeg, uas tuaj yeem tiv thaiv qhov luv Circuit Court ntawm cov theem tshwm sim los ntawm qhov ntev arc. Thaum muaj cua daj cua dub, peb yuav tsum xub rub theem nruab nrab, tom qab rub lub lee theem, thiab thaum kawg rub theem cua hauv qhov kev txiav txim ntawm lub zog tsis ua hauj lwm.
Thaum xa hluav taws xob, ob sab ntawm thawj theem, tom qab theem nruab nrab.
Thaum lub zog xa mus, thawj cua theem, tom qab ntawd rov mus rau theem phoenix, thiab thaum kawg theem nruab nrab, txhawm rau txhawm rau tiv thaiv luv Circuit Court los ntawm cua arc.
Daim ntawv ceeb toom teeb tsa
Ceev faj rau kev teeb tsa hluav taws xob poob qis
1, kev teeb tsa yuav tsum yog qhov nrawm nrawm (yaj los ntawm kwv yees li 24.5N nro), txwv tsis pub yooj yim ua rau kov cov plaub hau kub.
2, lub fuse teeb tsa ntawm tus ntoo khaub lig (thav duab) yuav tsum ruaj khov thiab txhim khu kev qha, tsis tuaj yeem muaj qhov tshee lossis tshee tshwm sim.
3. Cov yeeb yaj kiab yaj yuav tsum muaj lub Dip Angle ntawm 25 ° ± 2 °, yog li cov yeeb yaj kiab yaj tuaj yeem ntog sai los ntawm nws tus kheej qhov hnyav thaum qhov sib tov yaj.
4. Lub fuse yuav tsum tau teeb tsa rau ntawm caj npab hla (thav duab) nrog ntsug nrug tsis pub tsawg dua 4m ntawm hauv av. Yog tias nws tau teeb tsa saum toj no lub tshuab hluav taws xob faib khoom, nws yuav tsum ua kom muaj kab rov tav nrug ntau dua 0.5m los ntawm sab nrauv sab nrauv ntawm tus xa hluav taws xob xa hluav taws xob, yog tias muaj lwm yam xwm txheej tshwm sim los ntawm cov kav dej poob.
5. Qhov ntev ntawm cov yeeb yaj kiab yaj yuav tsum tau kho kom haum. Nws yog qhov yuav tsum tau hais tias tus nplaig lub qhov ncauj tuaj yeem khawm ntau dua ob feem peb ntawm qhov ntev ntawm kev sib cuag tom qab kaw, yog li txhawm rau zam kev ua tsis raug ntawm kev poob ntawm nws tus kheej thaum ua haujlwm.
6. Cov yaj siv yuav tsum yog cov khoom lag luam ntawm cov chaw tsim khoom tsis tu ncua, thiab muaj qee yam khoom siv dag zog. Feem ntau, cov yaj tuaj yeem tiv taus lub zog tensile ntau dua 147N yam tsawg.
7. 10kV poob hom fuse raug teeb tsa sab nraum zoov, thiab qhov nrug nruab nrab ntawm theem yog ntau dua 70cm.
