CJB1 18mm Ububanzi 1p+N Iplagi kwiSaphuli seSekethe i-6ka iSigaba esinye soMfanekiso oboniswayo

CJB1 18mm Ububanzi 1p+N Iplagi kwiSaphuli seSekethe 6ka iSigaba esiSinye

Inkcazelo emfutshane:

1. Isicelo:Ukukhusela iintambo kunye nezixhobo ngokuchasene nokugcwala kunye nesekethe emfutshane.

2. Imigaqo ngokubanzi yokukhetha i-MCB.

2.1 Idatha yobugcisa yothungelwano kwindawo eqwalaselweyo:

Iinkqubo zomhlaba, i-short-circuit current kwindawo yofakelo lwe-circuit breaker, ekufuneka isoloko ingaphantsi komthamo wokuqhawuka kwesi sixhobo, umbane oqhelekileyo wenethiwekhi.

2.2 Kukho iimpawu ezi-3 zegophe zemagnethi yokusebenza:

I-B curve (3-5 In) ukukhusela kunye nokulawulwa kweesekethe malunga neentambo zobude kwiinkqubo ze-TN kunye ne-IT.

I-C curve (5-10 In) ukukhuselwa kunye nokulawulwa kweesekethe ngokuchasene nokugqithisa kunye neesekethe ezimfutshane;ukukhuselwa kwemithwalo yokumelana kunye ne-inductive kunye ne-low inrush current.

D ijika (10-20 In) ukhuseleko kunye nolawulo lweesekethe ngokuchasene nomthwalo ogqithisiweyo kunye neesekethe ezimfutshane;ukukhuselwa kweesekethe ezibonelela ngemithwalo nge-inrush current ephezulu ekuvaleni kweesekethe (i-LV/LV transformers, izibane zokuqhawula).

3. I-CJB1 yeyomsebenzi onyibilikayo ophezulu wangoku ukukhawulela amandla okuthotywa ngenxa yesekethe emfutshane ngowona mlinganiselo mkhulu.
