Thaum xaiv lub fuse tso tawm, xa mus rau cov ntsiab lus hauv qab no:
Rated voltage: yuav tsum ntau dua lossis sib npaug rau qhov ua haujlwm siab tshaj plaws. Piv txwv li, 10kV faib network tuaj yeem siv 10kV tso tawm fuse (xws li RW10-10F/100A, RW11-10F/200A, thiab lwm yam).
Rated tam sim no: Qhov ntsuas tam sim no ntawm lub fuse yuav tsum siab dua lossis sib npaug rau qhov ntsuas tam sim no ntawm lub fuse. Qhov ntsuas tam sim no ntawm lub fuse raug xaiv raws li hauv qab no:
-100kVA lossis saum toj no faib transformer high-voltage sab, xaiv 1.5 mus rau 2 npaug ntawm qhov ntsuas tam sim no ntawm cov khoom faib hluav taws xob siab-voltage sab.
-100kVA thiab hauv qab tis transformer high-voltage sab, xaiv 2 mus rau 3 npaug ntawm qhov ntsuas tam sim no ntawm cov khoom siv hluav taws xob faib hluav taws xob sab.
Distribution transformer low-voltage side, xaiv 1 mus rau 1.2 npaug ntawm qhov ntsuas tam sim no ntawm cov khoom siv hluav taws xob tsawg-voltage sab.
Ib puag ncig tej yam kev mob: Haum rau cov chaw sab nraum zoov uas tsis muaj hmoov av conductive, tsis muaj corrosive gas, thiab tsis muaj nplaim taws, tawg thiab lwm yam txaus ntshai ib puag ncig nyob rau hauv cov huab cua puag ncig, thiab txhua xyoo kub sib txawv piv nyob rau hauv ± 40 degree.
(Tshwj xeeb ib puag ncig tej yam kev mob thiab tsis tuaj yeem kho nrog peb lub tuam txhab Yueyang Electric Power)
Cov khoom zoo: Txhua qhov chaw yuav tsum ua kom tiav, lub ncej yuav tsum du thiab hloov tau, lub casting yuav tsum tsis muaj kab nrib pleb, xuab zeb qhov thiab xeb, lub porcelain lub cev yuav tsum zoo, thiab lub fuse tube yuav tsum tsis txhob muaj noo noo nqus, expansion los yog dabtsi yog khoov. .
Tshawb xyuas lub peev xwm luv luv: xyuas kom meej tias peb-theem luv luv-circuit muaj peev xwm ntawm qhov kev tiv thaiv yog tsawg tshaj li qhov txwv siab tshaj ntawm qhov ntsuas kev sib txuas ntawm lub fuse, tab sis yuav tsum muaj ntau dua qhov qis dua ntawm qhov ntsuas qhov kev sib txuas. Yog tias qhov ntsuas qhov kev sib txuas ntawm lub fuse loj dhau lawm, peb-theem luv-circuit muaj peev xwm ntawm lub kaw lus tiv thaiv yuav tsawg dua li nws qhov kev txwv qis, ua rau muaj teeb meem hauv kev tua cov arc thaum lub fuse yog yaj, ua rau muaj xwm txheej xws li hlawv. thiab tawg ntawm lub fuse raj.
Installation xav tau:
-Lub fuse yuav tsum tau nruj me ntsis thaum lub sij hawm installation (kom lub fuse raug rau lub tensile quab yuam ntawm txog 24.5N), txwv tsis pub nws yog ib qho yooj yim mus ua rau hu rau cua sov.
-Lub fuse yuav tsum tau muab ntsia ruaj khov thiab ntseeg tau ntawm tus ntoo khaub lig caj npab (thav duab) yam tsis muaj kev co lossis swaying.
Lub fuse raj yuav tsum muaj ib tug downward inclination ntawm 25 degree ± 2 degree, uas yog conducive rau lub fuse raj poob sai sai los ntawm nws tus kheej qhov hnyav thaum lub fuse yog yaj.
-Lub fuse yuav tsum tau muab ntsia rau ntawm ib tug ntoo khaub lig caj npab (thav duab) nrog ib tug ntsug nrug tsis tsawg tshaj li 4m los ntawm hauv av; Yog hais tias ntsia saum toj no lub transformer tis, nws yuav tsum tuav ib tug kab rov tav nyob deb ntawm ntau tshaj 0.5m los ntawm lub outermost contour ciam teb ntawm lub tis transformer.
-Qhov ntev ntawm lub fuse raj yuav tsum tau kho kom haum, thiab tus nplaig duckbill tuaj yeem buckle ntau tshaj li ob feem peb ntawm qhov ntev ntawm kev sib cuag tom qab kaw, thiab lub raj fuse tsis tuaj yeem thaiv cov duckbill.
-Thaum lub 10kV tso tawm fuse raug teeb tsa sab nraum zoov, qhov kev ncua deb ntawm theem mus rau theem yuav tsum siab dua 0.7m.
Kev ceev faj txog kev ua haujlwm: Feem ntau, kev ua haujlwm thauj khoom tsis raug tso cai, thiab tsuas yog cov khoom siv thauj khoom tsis raug cai (kab) raug tso cai ua haujlwm. Txawm li cas los xij, nyob rau hauv ceg kab ntawm 10kV tis kab ntawm cov kab hluav taws xob nyob deb nroog thiab cov khoom siv hluav taws xob faib hluav taws xob nrog lub peev xwm tsawg dua 200kVA, nws tuaj yeem ua haujlwm nrog kev thauj khoom raws li cov kev xav tau tshwj xeeb. Kev ua haujlwm yuav tsum tau ua los ntawm ob tus neeg (ib tus neeg saib xyuas thiab ib tus neeg ua haujlwm), hnav cov hnab looj tes insulating uas tau dhau qhov kev xeem, hnav cov khau khiab insulating thiab tsom iav, siv cov khoom tsim nyog insulating rods uas haum rau qib voltage, thiab nws yog txwv tsis pub. ua hauj lwm nyob rau hauv thunderstorms los yog los nag hnyav. Thaum qhib qhov hloov, thawj zaug tawg rau theem nruab nrab, tom qab ntawd lub leeward sab theem, thiab thaum kawg lub cua sab theem; qhov kev txiav txim yog qhov rov qab thaum kaw qhov hloov. Lub zog yuav tsum nyob nruab nrab thaum ua haujlwm. Tom qab kaw qhov hloov pauv, ua tib zoo xyuas tus nplaig duckbill buckling kev sib cuag kom ntseeg tau tias muaj kev sib cuag zoo.
Kev xaiv piv txwv: Yog tias lub tshuab hluav taws xob faib hluav taws xob qis dua 100kVA muaj qhov ntsuas tam sim no ntawm I ntawm qhov siab-voltage sab, qhov ntsuas tam sim no ntawm fuse tuaj yeem xaiv tau raws li (2 ~ 3) I; Yog hais tias nws yog ib tug transformer ntawm 100kVA thiab saum toj no, qhov ntsuas tam sim no ntawm high-voltage sab yog kuv, thiab cov ntsuas tam sim no ntawm lub fuse tuaj yeem xaiv raws li (1.5 ~ 2) I. Piv txwv li, rau 30kVA transformer, lub high-voltage sab voltage yog 10kV, thiab tam sim no yog hais txog 1.7A los ntawm kev suav, yog li qhov ntsuas tam sim no ntawm lub fuse tuaj yeem xaiv tau raws li 4-5A.
Nyob rau tib lub sijhawm, nws tseem yuav tsum tau them sai sai rau qhov tshwj xeeb tsis sib txawv ntawm cov qauv sib txawv, xws li RW series, HRW series, thiab lwm yam. Thaum xaiv qhov tseeb, cov ntsiab lus saum toj no yuav tsum tau txiav txim siab ua tiav raws li qhov xwm txheej tshwj xeeb kom ntseeg tau. uas tsim nyog tso tawm fuse raug xaiv. Tsis tas li ntawd, xaiv cov khoom tsim nyog thiab nruj me ntsis raws li kev teeb tsa thiab kev ua haujlwm.
