Hom cuout fuse:

Hom fuse yog qhov feem ntau siv luv luv-circuit tiv thaiv hloov rau cov ceg kab ntawm 10kV cov kab xa tawm thiab cov khoom xa tawm.Nws muaj cov yam ntxwv ntawm kev lag luam, kev lag luam yooj yim, muaj zog adaptability rau sab nraum zoov ib puag ncig thiab lwm yam.Nws yog dav siv nyob rau hauv thawj sab ntawm 10kV faib kab thiab faib transformers rau kev tiv thaiv thiab cov cuab yeej hloov thiab txiav ua hauj lwm.
 
Nws tau nruab rau ntawm ceg kab ntawm 10kV faib kab, uas tuaj yeem txo qhov kev ua haujlwm ntawm lub zog tsis ua haujlwm.Vim tias nws qhov pom tseeb disconnect point ntawm high-voltage drop-type fuse, nws muaj kev ua haujlwm ntawm kev sib cais hloov, uas tsim kom muaj kev nyab xeeb ua haujlwm rau cov kab thiab cov khoom siv, thiab ua kom muaj kev ruaj ntseg ntawm cov neeg ua haujlwm tu. tis transformer, nws tuaj yeem siv los ua qhov kev tiv thaiv tseem ceeb ntawm kev xa tawm transformer, yog li nws tau nrov nyob rau hauv 10kV tis kab thiab tis transformer.
 
Installation ntawm drop-type fuse:

(1) thaum lub sij hawm installation, cov yaj yuav tsum tau nruj (kom cov yaj yog hais txog 24.5N nro), txwv tsis pub nws yog ib qho yooj yim ua rau cov plaub hau kub.

(2) lub fuse yuav tsum ruaj khov thiab txhim khu kev qha rau ntawm crossarm (thav duab) yam tsis muaj kev cuam tshuam los yog co

(3) cov yeeb nkab molten yuav tsum muaj lub kaum sab xis ntawm 25 ° ± 2 °, kom cov yeeb nkab molten tuaj yeem poob sai sai los ntawm nws tus kheej qhov hnyav thaum yaj yog fused.

(4) lub fuse yuav tsum tau nruab rau ntawm lub transverse caj npab (thav duab) nrog ib tug ntsug nrug tsis pub tsawg tshaj 4m los ntawm hauv av.Yog tias ntsia saum toj ntawm lub tshuab hluav taws xob faib tawm, kab rov tav qhov nrug ntawm lub fuse thiab thaj tsam sab nraud ntawm lub tshuab hloov pauv yuav tsum khaws cia ntawm qhov deb ntawm ntau tshaj 0.5m, yog tias muaj lwm yam xwm txheej tshwm sim los ntawm kev poob ntawm lub fuse.

(5) qhov ntev ntawm lub fuse yuav tsum tau hloov mus rau theem nrab.Nws yog qhov yuav tsum tau hais tias tus nplaig ntawm duck beak tuaj yeem ntes tau ntau tshaj li ob feem peb ntawm qhov ntev ntawm kev sib cuag tom qab kaw, kom tsis txhob muaj qhov tsis ncaj ncees lawm ntawm kev ua haujlwm ntawm tus kheej.

(6) cov yaj siv yuav tsum yog cov khoom lag luam ntawm cov tuam txhab ib txwm muaj, thiab muaj qee yam kev siv lub zog, cov kev cai dav dav ntawm cov yaj tuaj yeem tiv taus tsawg kawg yog 147N ntau tshaj qhov nro.

(7) 10kV drop-type fuse yuav tsum tau muab tso rau sab nraum zoov thiab qhov kev ncua deb yuav tsum siab tshaj 70cm.
 
Kev ua haujlwm ntawm drop-type fuse:

Raws li ib txwm muaj, nws tsis raug tso cai rau kev khiav lag luam poob fuse nrog load, tsuas yog tso cai rau nws ua haujlwm tsis muaj cov khoom siv thauj khoom (kab). Txawm li cas los xij, cov khoom siv hluav taws xob faib hluav taws xob uas muaj peev xwm tsawg dua 200kVA thiab ceg kab ntawm 10kV faib kab hauv kev ua liaj ua teb. raug tso cai ua haujlwm hauv qab load raws li cov hauv qab no:

(1) kev ua haujlwm yuav tsum tau ua los ntawm ob tus neeg (ib tus neeg saib xyuas thiab ib tus neeg ua haujlwm), yog tias lawv yuav tsum hnav cov hnab looj tes insulating, insulating khau looj plab hlaub thiab tsom iav, thiab ua haujlwm nrog cov khoom tsim nyog insulating rods nrog rau cov qib voltage.Kev ua haujlwm raug txwv nyob rau hauv huab cua ntawm xob laim lossis los nag hnyav.

(2) thaum rub lub lag luam nres, nws feem ntau tau teev tseg kom rub lub nruab nrab theem ua ntej, tom qab ntawd lub leeward sab theem, thiab thaum kawg lub cua sab theem.Qhov no yog vim hais tias lub transformer faib los ntawm peb - ​​theem ua hauj lwm mus rau ob - theem ua hauj lwm, rub lub nruab nrab theem uas tsim los ntawm qhov tsawg kawg nkaus arc spark, yuav tsis ua rau ib tug luv luv Circuit Court ntawm.Qhov thib ob yog ua txhaum lub leeward sab theem, vim hais tias lub intermediate theem tau raug rub tawm, lub leeward sab theem thiab lub windward sab theem nrug ob npaug, txawm tias muaj ib qho overvoltage, uas ua rau luv luv Circuit Court ntawm qhov ua tau yog me me heev.Thaum kawg, thaum lub sij hawm upwind yog rub, tsuas yog lub capacitive tam sim no mus rau hauv av, lub txim tshwm sim tau me ntsis.

(3) Thaum lub kaw lus kaw, kev ua haujlwm ua ntu zus yog thim rov qab thaum lub hloov pauv tau rub.Ua ntej, lub upwind side theem kaw, ces lub leeward sab theem yog kaw, thiab thaum kawg lub intermediate theem yog kaw.

(4) kev ua haujlwm ntawm lub raj molten yog ib qhov project nquag.Yog tias koj tsis xyuam xim rau nws, nws yuav ua rau kev sib cuag kub hnyiab thiab ua rau kev sib cuag tsis zoo.Kev sib cuag yuav overheated thiab lub caij nplooj ntoos hlav yuav tsum annealed.Yog li ntawd, rub, kaw lub melting tube kom muaj zog nruab nrab, kaw zoo, ua tib zoo xyuas tus nplaig tuaj yeem nruj buckle tus nplaig tus nplaig ob feem peb ntawm qhov ntev ntawm qhov saum toj no, koj tuaj yeem rub. tus nres bar nuv ntawm lub qhov ncauj ntawm tus os kom nias down ob peb zaug, thiab maj mam sim rub, xyuas seb nws puas zoo. Tsis txhob kaw qhov hloov ntawm qhov chaw los yog tsis kaw ruaj khov, qhov sib cuag zoo li qub ntawm lub fuse siab yog tsis txaus, nws yog ib qho yooj yim ua rau kev sib cuag kub hnyiab los yog lub raj melting poob
