Pua pua ntawm amperes mus rau ntau tshaj 1000 amperes ntawm load range, yuav ua li cas xaiv lub Circuit Court breaker

Moulded case Circuit Breakersyog ntsuas los ntawm 10A txog 1600A, thiabFrame Circuit Breakers (ACB)yog ntsuas los ntawm 630A txog 6300A.Saib molded case Circuit Court breaker thiabcua Circuit Court breakerrated tam sim no overlap cheeb tsam, tej zaum tsis paub yuav ua li cas xaiv.

Muaj ob peb lub hauv paus ntsiab lus ntawm no.

Ib qho kev faib khoom tseem ceeb hauv kev faib khoom, uas muaj ob lub voj pub noj thiab lub voj voog lub cev muaj zog.

Cov khoom tiv thaiv ntawm cov khoom noj khoom noj hluav taws xob yog lub cable.Nyob rau tib lub sijhawm, pubCircuit Court breakeryuav tsum paub txog kev tiv thaiv kev sib raug zoo nrog lub ntsiab tuajCircuit Court breakerntawm theem nrab faib system, yog li pubCircuit Court breakeryuav tsum muaj luv luv Circuit Court ncua S tiv thaiv.

Thermomagneticmolded rooj plaub Circuit Court breakermuaj tsuas yog ob ntu ntawm kev tiv thaiv, uas yog, overload ntev ncua L parameter thiab luv luv Circuit Court instantaneous I parameter, tsis haum rau lub voj ntawm cov kab noj ntev, thiab siv covhluav taws xob molded rooj plaub Circuit Court breakernrog peb ntu ntawm kev tiv thaiv.

Rau lub cev muaj zog circuits, siv ib qho sib nqus Circuit Court breaker, uas yog, tsuas yog luv luv Circuit Court tiv thaiv, tsis muaj overload tiv thaiv Circuit Court breaker.Pom tau, qhov no kuj txawv ntawm cov payas rooj plaub Circuit Court breaker.

Tsis tas li ntawd, yog hais tias muaj ib qho kev sib cais transformer ntawm qhov hluav taws xob ntawm lub qhov hluav taws xob, vim hais tias lub transformer inrush tam sim no yog kwv yees li sib npaug zos rau luv luv tam sim no, qhov ntsuas tam sim no ntawm Circuit Court breaker tuaj yeem xaiv raws li 1.6 npaug ntawm qhov ntsuas tam sim no. lub transformer thaum xam.Yog hais tias qhov kev rho tawm transformer muaj peev xwm loj,cua Circuit Court breakerszoo li yuav siv tau.

Piv txwv li, 250kVA 0.4kV rau 0.4kV rho tawm transformer, impedance voltage yog 6%, nws ntsuas tam sim no yog:

Short-circuit tam sim no yog:

Peb faib qhov luv-circuit tam sim no los ntawm 10 kom tau 600A, yog li peb siv lub Circuit Court breaker nrog cov ntsuas tam sim no ntawm 630A li niaj zaus.

Txawm li cas los xij, peb xav txog qhov cuam tshuam lub sijhawm ntev ntawm qhov excitation inrush tam sim no, peb xav siv luv luv Circuit Court ncua S parameter kom ncua, ces 630A molded case Circuit breaker tsis zoo, siv 800A thav duab Circuit Court breaker, thav duab Circuit Court breaker luv luv Circuit Court ncua sij hawm. ntev dua.

Tsis tas li ntawd, thaum xav txog cov kab hluav taws xob sab nraud, nws yog ib qho tsim nyog los xyuas qhov thermal stability ntawm lub cable, uas yuav ua rau kom tus nqi tam sim no ntawm lub Circuit Court breaker.

Pom tau, peb yuav tsum xav txog yam khoom siv hluav taws xob twg los xaiv.
