Daim Ntawv Thov: RDM1L series molded case circuit breaker, feem ntau yog siv rau lub voj voog faib khoom ntawm AC50 / 60Hz, qhov ntsuas hluav taws xob ua haujlwm yog 400V, ntsuas tam sim no txog li 800A rau kev muab kev tiv thaiv tsis ncaj qha thiab tiv thaiv hluav taws los ntawm qhov txhaum grounding tam sim no, thiab nws kuj tuaj yeem siv rau kev faib hluav taws xob thiab kev tiv thaiv circuit tiv thaiv overload thiab luv-circuit, nws kuj ua haujlwm rau kev hloov pauv circuit thiab pib lub cev muaj zog tsis tshua muaj. Cov khoom no yog siv rau tus qauv ntawm IEC 60947-2.
Kev ua haujlwm ib txwm muaj thiab kev teeb tsa ib puag ncig:
3.1 Kub: tsis pub siab tshaj +40 ° C, thiab tsis pub qis dua -5 ° C, thiab qhov nruab nrab kub tsis pub siab tshaj +35 ° C.
3.2 Qhov chaw teeb tsa tsis pub tshaj 2000m.
3.3 Cov av noo: tsis pub tshaj 50%, thaum Kub yog +40 ° C. Cov khoom tuaj yeem tiv taus cov av noo siab dua hauv qab qhov kub qis dua, piv txwv li, thaum kub ntawm +20 ° C, cov khoom tuaj yeem tiv taus 90% av noo.
Qhov dej noo uas tshwm sim vim yog qhov kub hloov pauv yuav tsum tau saib xyuas nrog kev ntsuas tshwj xeeb
3.4 Chav Kawm ntawm kev ua qias tuaj: Chav Kawm 3
3.5 Nws yuav tsum tau ntsia rau ntawm qhov chaw uas tsis muaj kev phom sij ntawm kev tawg, nws kuj tsis muaj roj thiab cov hmoov av uas yuav ua rau hlau-xeb thiab rwb thaiv tsev-kev puas tsuaj.
3.6 Lub kaum sab xis siab tshaj plaws ntawm lub installation yog 5°, nws yuav tsum tau ntsia rau ntawm qhov chaw uas tsis muaj kev cuam tshuam thiab kev cuam tshuam los ntawm huab cua.
3.7 Hom kev teeb tsa lub voj voog tseem ceeb: III, Hom kev teeb tsa lub voj voog pabcuam thiab kev tswj hwm: 11
3.8 Lub zog sib nqus sab nraud ntawm qhov chaw teeb tsa yuav tsum tsis pub tshaj 5 npaug ntawm lub zog sib nqus hauv ntiaj teb.
3.9 Kev teeb tsa ib puag ncig electromagnetic: B hom
Cov txheej txheem tseem ceeb:
