RW12F 15/24KV 100/200A sab nraum zoov high voltage AC poob fuse nrog arc extinguishing ntaus ntawv
Product Description
RW12F series tso tawm fuses yog sab nraum zoov hluav taws xob tiv thaiv cov khoom siv hluav taws xob hauv kev xa hluav taws xob thiab kev faib khoom.Lawv tau nruab rau ntawm high-voltage sab ntawm faib transformers los yog nyob rau hauv ceg kab ntawm faib kab, thiab yog siv rau luv luv Circuit Court thiab overload tiv thaiv ntawm transformers thiab kab, raws li zoo raws li cais thiab ua ke load tam sim no.Lub high-voltage ceramic drop-out fuse yog tsim los ntawm ceramic insulating bracket thiab ib lub raj fuse.Qhov kev sib cuag zoo li qub yog ntsia rau ntawm ob qho kawg ntawm cov khoom siv insulating, thiab cov kev sib cuag txav tau raug ntsia ntawm ob qho kawg ntawm lub raj fuse.Lub fuse tube yog tsim los ntawm lub puab arc suppression raj thiab lub fuse raj.Cov txheej txheej txheej yog tsim los ntawm phenolic ntawv raj lossis epoxy iav daim ntaub raj.Lub load poob hom fuse txhim khu lub elastic auxiliary tiv tauj thiab arc extinguishing npog los faib thiab muab cov load tam sim no.

Fuse installation thiab ua haujlwm
1. Kev teeb tsa ntawm kev poob fuse:
(1) Lub yaj yuav tsum tau nruj me ntsis thaum lub sij hawm installation (kom cov yaj yog raug rau lub tensile quab yuam ntawm txog 24.5N), txwv tsis pub nws yog ib qho yooj yim ua rau kev sib cuag mus rau overheat.
(2) Lub fuse ntsia rau ntawm tus ntoo khaub lig caj npab (thav duab) yuav tsum ruaj khov thiab txhim khu kev qha, thiab yuav tsum tsis txhob co los yog co.
(3) Lub raj melting yuav tsum muaj lub kaum sab xis downward ntawm 25 ° ± 2 °, kom lub raj yaj tuaj yeem poob sai sai los ntawm nws tus kheej qhov hnyav thaum lub yaj yog tshuab.
(4) Lub fuse yuav tsum tau muab ntsia rau ntawm tus ntoo khaub lig caj npab (thav duab) nrog txoj kab ntsug tsis pub tsawg tshaj 4m los ntawm hauv av.Yog tias nws tau teeb tsa saum toj ntawm lub tshuab hluav taws xob faib khoom, nws yuav tsum tuav txoj kab rov tav ntawm ntau dua 0.5m los ntawm sab nrauv contour ciam teb ntawm lub transformer.Ib qho kev poob ntawm lub raj melting ua rau lwm yam xwm txheej.
(5) Qhov ntev ntawm lub raj fuse yuav tsum tau kho me ntsis.Nws yuav tsum tau hais tias tus nplaig duckbill muaj peev xwm tuav tau ntau tshaj li ob feem peb ntawm qhov ntev ntawm kev sib cuag tom qab kaw, kom tsis txhob muaj qhov yuam kev ntawm tus kheej poob thaum lub sijhawm ua haujlwm, thiab lub raj fuse yuav tsum tsis txhob ntaus lub duckbill., nyob rau hauv thiaj li yuav tiv thaiv lub melting raj los ntawm ntog nyob rau hauv lub sij hawm tom qab lub melting tshuab.
(6) Cov yaj siv yuav tsum yog cov khoom lag luam ntawm cov chaw tsim khoom ib txwm muaj, thiab muaj qee yam khoom siv zog.Feem ntau, cov yaj yuav tsum tau tiv taus lub zog tensile ntau tshaj 147N.
(7) Lub 10kV tso tawm fuse yog ntsia sab nraum zoov, thiab qhov kev ncua deb ntawm theem yuav tsum siab tshaj 70cm.
Thib ob, kev ua haujlwm ntawm qhov poob fuse:
Raws li ib txwm muaj, nws tsis raug tso cai rau kev khiav lag luam fuse nrog load, tsuas yog tso cai rau kev khiav lag luam cov khoom siv tsis muaj load (kab).Txawm li cas los xij, cov kab ntawm 10kV cov kab xa tawm hauv cov kab hluav taws xob nyob deb nroog thiab cov khoom siv hluav taws xob faib hluav taws xob uas muaj peev xwm tsawg dua 200kVA raug tso cai ua haujlwm nrog kev thauj khoom raws li cov hauv qab no:
(1) Kev ua haujlwm yuav tsum tau ua los ntawm ob tus neeg (ib tus saib xyuas thiab ib tus ua haujlwm), tab sis yuav tsum hnav cov hnab looj tes insulating, insulating boots, thiab tsom iav, thiab ua haujlwm nrog cov khoom tsim nyog insulating rods nrog cov qib sib piv.Kev ua haujlwm raug txwv thaum los nag hnyav.
(2) Thaum lub sijhawm ua haujlwm ntawm lub rooj vag, nws feem ntau txhais tau tias qhov nruab nrab theem yog rub ua ntej, tom qab ntawd lub leeward sab theem yog rub, thiab tom qab ntawd cov cua ntsawj sab yog rub.Qhov no yog vim hais tias lub transformer faib yog hloov los ntawm peb-theem kev khiav hauj lwm mus rau ob-theem kev ua hauj lwm, thiab lub arc spark generated thaum lub intermediate theem tawg yog me me, uas yuav tsis ua rau ib tug luv luv Circuit Court ntawm theem.Qhov thib ob yog txhawm rau txhawm rau theem leeward sab, vim tias theem nruab nrab tau raug rub tawm, thiab qhov kev ncua deb ntawm lub leeward sab theem thiab cua sab cua theem tau ob npaug.Txawm hais tias muaj qhov overvoltage, qhov ua tau ntawm luv luv Circuit Court ntawm theem yog tsawg heev.Thaum lub windward sab theem yog rub rov qab, tsuas muaj ib tug capacitive tam sim no rau hauv av, thiab lub txim generated yog heev me ntsis.
(3) Thaum kaw, kev ua haujlwm ua ntu zus yog thim rov qab thaum kaw, thawj zaug kaw qhov cua sab hauv theem, tom qab ntawd kaw lub leeward sab theem, thiab tom qab ntawd kaw qhov nruab nrab theem.
(4) Kev khiav hauj lwm lub raj melting yog ib yam khoom nquag.Yog tias koj tsis xyuam xim, nws yuav ua rau kev sib cuag kub hnyiab thiab ua rau kev sib cuag tsis zoo, overheat kev sib cuag, thiab anneal lub caij nplooj ntoos hlav, uas yuav ua rau kev sib cuag tsis zoo thiab tsim lub voj voog vicious.Yog li ntawd, thaum rub thiab kaw lub fusion raj, siv lub zog nruab nrab.Tom qab kaw, ua tib zoo xyuas tias tus nplaig duckbill tuaj yeem nruj nreem buckled rau ntau tshaj li ob feem peb ntawm qhov ntev ntawm tus nplaig.Koj tuaj yeem siv lub pas nrig txhawm rau txhawm rau txhawm rau lub duckbill sab saud thiab nias ob peb zaug.Sim rub dua los xyuas seb nws haum zoo.Thaum lub kaw lus kaw, nws tsis nyob hauv qhov chaw lossis tsis ruaj khov, thiab qhov kev sib cuag zoo li qub ntawm lub fuse tsis txaus, uas tuaj yeem yooj yim ua rau kev sib cuag los yog lub raj fuse poob los ntawm nws tus kheej.
