Intshayelelo yeMveliso

I-RDB8A-63 miniature circuit breaker (ebizwa ngokuba yi-circuit breaker), esetyenziswa kakhulu kwimigca yokusasazwa kokhuseleko ene-AC 50Hz, i-voltage yokusebenza elinganisiweyo engadluli kwi-400V, i-current rated engadluli kwi-63A, kunye ne-short-circuit breaker capacity engadluli kwi-6000A; ingasetyenziswa nakwi-DC voltage unipolar engadluli kwi-110V, iipali ezimbini ezingadluli kwi-220V, i-DC current engadluli kwi-63A, i-DC short-circuit breaker capacity engadluli kwi-6000A kwimigca yokusasazwa yokukhusela; isetyenziselwa uqhagamshelo olungaqhelekanga, ukwaphuka nokutshintsha imigca, kunye nokugqithisa, umsebenzi wokukhusela i-short circuit. Kwangaxeshanye, ineemodyuli zomsebenzi ezinamandla zokuncedisa, ezifana noqhagamshelwano oluncedisayo, unxibelelwano olune-alamu, ukukhululwa kwe-shunt, ukukhululwa kwe-undervoltage, ulawulo lokuhamba olukude kunye nezinye iimodyuli.

Iimbonakalo

1. Inkqubo yokusebenza eqinisekisiweyo

2.Umthamo omncinci, umthamo omkhulu

3. Umthamo wocingo onamandla kakhulu

4.Ubushushu obuhle phakathi kwezigaba

5. Ukuqhuba okunamandla kakhulu

6. Ukunyuka kobushushu obuphantsi kunye nokusetyenziswa kwamandla

Idatha yobugcisa ephambili

Iimpawu zokukhubeka komsinga ogqithisileyo: Phantsi kweemeko eziqhelekileyo zokufakelwa kunye nobushushu obuqhelekileyo (30-35)°C

iimpawu zokukhubeka ngokugqithisileyo kwe-circuit breaker ziyahlangabezana neemfuno ezikwiTheyibhile 1.

Umthamo wokuqhekeka kwesekethe emfutshane olinganisiweyo we-circuit breaker uboniswe kwiTheyibhile 2.

I-lfe yoomatshini kunye nombane: Phantsi kwe-voltage echaziweyo, i-circuit breaker yenza kwaye iphule i-current elinganisiweyo, i-power factor yi-0.85-0.9, kwaye ivavanywa kwi-frequency ye-120 (>32A) okanye i-240 (>32A) yemijikelo yokusebenza ngeyure. Ubomi boomatshini kunye nombane buphindwe ka-4000.
