Cov xwm txheej ntawm kev siv

Ib txwm siv tej yam kev mob thiab parameter kho

Cov fuses ua haujlwm ib txwm ua raws li cov xwm txheej hauv qab no yam tsis muaj kev kho ntxiv. Thaum nws dhau qhov kev siv ib txwm siv, qee qhov kev txwv lossis kev sib tham yuav tsum raug kho yog tias lawv nyob hauv qhov kev tso cai siv. Yog tias nws dhau ntawm qhov kev tso cai siv cov xwm txheej, koj yuav tsum sab laj nrog peb lub tuam txhab, thiab ua raws li kev ntsuas kev ua haujlwm thiab kev ntsuas ntawm cov xwm txheej.

Nws raug pom zoo tias tus nqi tam sim no ntawm lub sijhawm ntev yuav tsum tsis txhob ntau tshaj 80% ntawm qhov ntsuas tam sim no.

Ambient Cua Kub

Cov xwm txheej siv li qub:-5℃～40℃。

Tso cai tej yam kev mob: -40℃～85℃。

Ambient Air Temperature hloov parameter kho: thaum ua haujlwm hauv qab-5℃, Fuse’s Tsawg zog dhau-load, dhau-tam sim no, pre-arc lub sij hawm ntev me ntsis, ntsuas tam sim no loj me ntsis. Tshwj tsis yog - 5 ℃ tsis yog qhov ua haujlwm ntau, feem ntau yuav tsis xav txog ntxiv Fuse’s ntsuas tam sim no. Fuse ua haujlwm saum toj no40℃, ntsuas tam sim no xav tau kev kho ntxiv, kho qhov ntsuas yog-Kt.

Lus Cim 1: Kt span twb suav hais tias yog Fuse’s rated tam sim no cuam tshuam ntawm kev nyab xeeb margin nyob rau hauv ib txwm ua hauj lwm tej yam kev mob.

Lus Cim 2: ambient cua kub yuav tsum tau txuas ntxiv 1-2 teev thiab ntau dua, nws’yuav muaj teeb meem cuam tshuam.

Aqhov siab

Kev siv li qub

Qhov siab tsis tshaj 3000m.

Tso cai siv yam mob

2000m－4500m。

Altitude hloov parameter kho: siab altitude feem ntau ua rau rwb thaiv tsev deterioration, Deterioration ntawm tshav kub dissipation tej yam kev mob, Cua siab hloov.

a) Thaum qhov siab nce 100m, Fuse’s kub nce0.1-0.5k.

b) Thaum qhov siab nce 100m, Ambient kub poob ib ncig ntawm qhov nruab nrab 0.5k.

c) Cov xwm txheej zoo li qub, siv Fuse hauv qhov chaw qhib, tuaj yeem tsis saib xyuas qhov siab ntawm qhov ntsuas tam sim no, tseem siv tau raws li tus qauv. Yog nws’s dhau40℃, yuav tsum tau derating ntawm rated tam sim no. Thaum qhov siab nce 1000m, ntsuas tam sim no derate2%-5%.

Nco tseg: Nyob rau hauv tib lub dimension series, qhov siab tshaj plaws nyob rau tam sim no txais ib tug ntau dua derating piv, qis rated tam sim no siv qis derating ratio. Qhov cuam tshuam ntawm huab cua rwb thaiv tsev lub zog (lub zog tawg) ntawm qhov siab.

A) Thaum qhov siab nce siab, huab cua rwb thaiv tsev lub zog poob qis. Ntawm 2000-4500 meters, Thaum qhov siab nce 1000m, ntsuas tam sim no derate 12-15%. Siv rauGB/T16935.1, Kho qhov rwb thaiv tsev qhov sib txawv raws li.

B)Qhov kev ncua deb ntawm cov fuse terminals feem ntau yog ntau dua li GB / T16935.1, Table A1, A2 rwb thaiv tsev qhov sib txawv raws li tus qauv. Tsuas yog rau ib tus neeg fuses nrog lub ntim me me, tsis tas yuav kuaj qhov sib txawv ntawm rwb thaiv tsev.

C)Rwb thaiv tsev sib txawv ntawm txoj siv fuse thiab lwm cov qauv nyob, thiab rau hauv av, tus neeg siv yuav tsum xav txog qhov cuam tshuam ntawm qhov siab.

Atmospheric tej yam kev mob

Cov xwm txheej ua haujlwm li qub:

Cov huab cua yog huv si, nws cov txheeb ze av noo tsis ntau tshaj 50% thaum kub siab tshaj40℃.

Thaum qhov kub thiab txias, qhov txheeb ze humidity tuaj yeem siab dua me ntsis, piv txwv li, ntawm20℃, txheeb ze humidity tuaj yeem yog 90%.

Nyob rau hauv cov xwm txheej no, vim tias qhov kub thiab txias hloov, qhov nruab nrab condensation tuaj yeem tshwm sim los ntawm kev sib tsoo.

Tso cai ua hauj lwm tej yam kev mob.

Yog tsis pom tseeb condensation, tus txheeb ze humidity tuaj yeem ncav cuag 95%.

Kev vibration ib puag ncig thiab muaj peev xwm tiv taus av qeeg thiab lwm yam kev puas tsuaj

Cov fuses no muaj kev tiv thaiv zoo rau kev co thiab kev poob siab, thiab tuaj yeem tiv taus kev nrawm dua 10g.

Qhov kev tiv thaiv ntawm no series ntawm fuses rau kev vibration thiab poob siab yog nyob rau hauv txoj kab nrog rau Class II daim ntawv thov ib puag ncig ntawm kev tsheb ciav hlau.

Qhov kev tiv thaiv ntawm no series ntawm fuses rau kev co thiab kev poob siab yog haum rau cov tsheb loj.Daim ntawv thov ib puag ncig nrog kev vibration muaj zog yog feem ntau kuaj thiab txheeb xyuas.

Filthy Premium

Cov pa phem raws li qibIII.

Ib txwm ua haujlwm

A)Cov fuses tau muab cais rau hauv cov huab cua uas tsis muaj cua, ntxiv rau kev sib txuas ntawm cov xov hlau, tsis muaj lwm yam khoom siv hluav taws xob los yog cov cua kub dissipating hauv 1m.

B)Lub fuse txuas terminals yuav tsum xyuas kom ruaj khov thiab txhim khu kev qha hluav taws xob tiv tauj, tiv thaiv kev tiv thaiv yuav tsum tsis txhob cuam tshuam rau kev ua haujlwm fuse.

C) Lub fuse tuaj yeem ntsia tau vertically, horizontally lossis obliquely. Yog tias tso siab rau lub caij nplooj ntoo hlav kom ntseeg tau tias cov hluav taws xob sib txuas fuse, thaum txhim kho, qhov chaw tsim nyog yuav tsum raug xaiv kom tsis txhob muaj kev cuam tshuam tsis zoo ntawm lub ntiajteb txawj nqus thiab kev co ntawm cov hluav taws xob sib txuas.

Forced cua txias

Kev siv cov cua txias txias tuaj yeem ua kom cov cua sov dissipation ntawm lub fuse, cnce qhov ntsuas tam sim no ntawm fuse. Kho qhov tseem ceeb rau cua ceev thiab ntsuas tam sim no-Kv

A) Thaum txhim kho Fuse, qhov tsawg kawg nkaus qhov sib txawv ntawm fuses ntawm ob lub fuses uas nyob ib sab ua tau raws li qhov yuav tsum tau muaj rwb thaiv tsev, Yog tias tsim nyog, nruab qhov rwb thaiv tsev ntawm cov fuses, txhawm rau tiv thaiv luv luv ntawm cov theem thaum hloov lub fuse.

B) Ua ke nrog kev saib xyuas cov khoom siv hluav taws xob tsis tu ncua, nqa tawm kev tshuaj xyuas thiab tu, tshem tawm cov plua plav, Oxide txheej hauv kev sib cuag nrog cov khoom siv hluav taws xob, thiab lwm yam.

C) Cov fuses uas muaj kev puas tsuaj yuav tsum tau hloov.

D) Tshwj tsis yog tso cai los ntawm kev siv cov cai, yogFuse loadhauvhloov, oli ntawd, tsis txhob hloov lub

fuse nrog load.
