CJB1 18mm Ububanzi 1P 2P 3P 4P Iplagi yeSekethe i-6ka Single Phase Umfanekiso obonisiweyo

CJB1 18mm Ububanzi 1P 2P 3P 4P Iplagi yoMphuhlisi weSekethe 6ka Isigaba esinye

Inkcazo emfutshane:

1. Isicelo: Ukukhusela iintambo kunye nezixhobo ngokuchasene nokugqithisa kunye nokujikeleza okufutshane.

2. Imithetho ngokubanzi yokukhetha i-MCB.

2.1 Idatha yobugcisa yenethiwekhi kwindawo eqwalaselweyo:

Iinkqubo zokugquma umhlaba, umsinga we-short-circuit kwindawo yokufakela i-circuit breaker, ekufuneka ihlale ingaphantsi komthamo wokuqhekeza wesi sixhobo, inethiwekhi ye-voltage eqhelekileyo.

2.2 Kukho iimpawu ezi-3 zegophe lokusebenza kwemagnethi:

Ukhuselo kunye nolawulo lwe-B curve (3-5 In) lweesekethe ngokuchasene neentambo zobude kwiinkqubo ze-TN kunye ne-IT.

Ukhuselo kunye nolawulo lwe-C curve (5-10 In) lweesekethe ngokuchasene nokugqithisa kunye neesekethe ezimfutshane; ukhuseleko kwimithwalo ekhuselayo kunye neyokungenisa ene-inrush ephantsi.

Ukhuselo kunye nolawulo lwe-D curve (10-20 In) lweesekethe ngokuchasene nokugqithisa kunye neesekethe ezimfutshane; ukhuseleko lweesekethe ezibonelela ngemithwalo ene-inrush current ephezulu xa kuvalwa isekethe (ii-transformers ze-LV/LV, izibane ze-breakdown).

3. I-CJB1 inamandla aphezulu okunciphisa amandla okuchithwa ngenxa ye-short circuit ngokubanzi.
