Ib puag ncig ntawm daim ntawv thov

• Kub ib puag ncig: -35 ~ 70 ° C
• Qhov siab ntawm qhov chaw teeb tsa: ≤2500m.
• Qhov av noo: tsis pub tshaj 50% ntawm qhov kub siab tshaj plaws ntawm +40 ° C Yog tias qhov kub qis dua, qhov av noo siab dua yuav raug tso cai. Piv txwv li thaum qhov av noo yog 90% ntawm qhov kub ntawm 20 ° C, yuav tsum muaj kev ntsuas tshwj xeeb los daws cov dej noo ntawm qhov chaw, uas yuav tshwm sim vim qhov kub hloov pauv.
• Kev tiv thaiv kev ua qias tuaj: qib 3.
• Txhim kho pawg: llI rau cov breakers 'lub voj voog tseem ceeb.
• Lub teb sib nqus sab nraud ntawm qhov chaw teeb tsa ntawm lub tshuab hluav taws xob yuav tsum tsis pub tshaj 5 npaug ntawm lub teb geomagnetic hauv txhua qhov kev taw qhia.
• Cov khoom tawg yuav tsum tau teeb tsa rau hauv qhov chaw uas tsis muaj cov khoom tawg, cov hmoov av conductive thiab tsis tuaj yeem corrode hlau thiab rhuav tshem cov rwb thaiv tsev.
• Tag nrho cov koob ntawm cov hluav taws xob Circuit Court tuaj yeem ntsia tau kab rov tav (transverse) lossis ntsug (upright).

Cov qauv ntawm daim ntawv thov

• Cov breakers ua raws li cov kev xav tau ntawm cov qauv hauv qab no:
• IEC 60947-1 GB/T14048.1 Cov cai dav dav
• IEC 60947-2 GB/T14048.2 Cov cuab yeej hluav taws xob

Siv thiab txij nkawm

• Tsis txhob siv tes ntub dej ua haujlwm lub tshuab hluav taws xob, txwv tsis pub yuav muaj xwm txheej hluav taws xob poob siab.
• Cov cuab yeej hluav taws xob yuav tsum tsis txhob ua haujlwm ntau zaus, txwv tsis pub nws yuav ua rau lub neej ua haujlwm ntawm lub cuab yeej hluav taws xob luv dua.
• Xyuas kom tseeb tias cov kev sib txuas ntawm lub davhlau ya nyob twg thiab cov ntsia hlau txuas tau raug khi kom ruaj khov yam tsis muaj kev xoob.
• Xyuas seb cov xov hlau puas yog.
• Siv lub megohmmeter los ntsuas qhov tsis kam ntawm cov rwb thaiv tsev ntawm cov theem thiab ntawm cov theem thiab hauv av.
• Paub tseeb tias qhov faib theem ntawm lub voj voog hluav taws xob puas tau teeb tsa kom raug.
• Thaum txhim kho lub circuit breaker nrog lub undervoltage release, lub undervoltage release yuav tsum txuas nrog lub rated voltage ua ntej kaw lub circuit breaker, Lub circuit breaker nyob rau hauv lub xeev kaw.
• Nruab cov circuit breakers nrog cov auxiliary thiab alarm contacts. Thaum kaw lossis qhib lub circuit breaker, lub auxiliary contact signal yuav tsum tau hloov pauv li qub, nias lub khawm emergencytrip, thiab lub alarm contact signal yuav tsum tau hloov pauv li qub.
• Yog tias lub tshuab hluav taws xob muaj lub tshuab hluav taws xob lossis tes ua haujlwm, siv lub tshuab ua haujlwm kom qhib thiab kaw 3-5 zaug, xyuas kom meej tias kev ua haujlwm txhim khu kev qha thiab ib txwm muaj.
• Cov yam ntxwv thiab cov khoom siv ntawm lub circuit breaker yog teem los ntawm lawv tus tsim khoom thiab tsis tuaj yeem hloov kho tau raws li qhov xwm txheej thaum siv. Nyob rau hauv qhov xwm txheej uas tus neeg siv ua raws li cov xwm txheej khaws cia thiab siv, lub foob ntawm lub circuit breaker yuav tsum nyob ruaj khov hauv 24 lub hlis txij li hnub xa khoom los ntawm tus tsim khoom. Yog tias cov khoom puas tsuaj lossis siv tsis tau raws li qhov xwm txheej zoo ntawm kev tsim khoom, tus tsim khoom muaj lub luag haujlwm hloov thiab kho dawb.
