Njengoko siyazi, ukukhusela i-device yokukhusela iya kuhlaziywa okanye kufike ekupheleni kokuphila emva kwexesha ngenxa yokuqhuma okuncinci, ukuqhutywa komzimba oluqinileyo okanye ukuqhubela ngamandla. Yaye xa isistim sokukhusela singaphumeleli, sinokudala imeko yesigqeba esifutshane kwaye kubangele ingxaki yokukhusela kwinkqubo yamandla. Ngaloo ndlela ifowuni yokukhusela i-overcurrent ifunekayo ukuze isebenze kunye kunye nefowuni yokukhusela.
Kukho ngokuqhelekileyo iintlobo ezimbini zedivaysi yokukhusela i-overcurrent esebenzisana kunye ne-SPD yokukhusela ukukhusela: i-circuit breaker kunye nefusethi. Ngoko, yintoni i-Pros and Cons ngokulandelanayo?
Umephuli wojikelezo
eziluncedo
- Unokusetyenziswa ngokuphindaphindiweyo kwaye unciphise iindleko zokugcina.
nezingeloncedo
- Iba nokuhla okukhulu kwevolthi xa ujongene nongxamiseko lwangoku kwaye ke kuya kulithoba inqanaba lokukhusela le-SPD
Fuse
eziluncedo
- Mhlawumbi kunokwenzeka ukungasebenzi
- Umthamo ophantsi ulahla ngoku
- Imveliso ngokwayo ixabiso elibi ngakumbi ngokukodwa kwiimeko ezimfutshane zesekethe zangoku
nezingeloncedo
- Emva kokuba isebenze, i-fuse kufuneka ithathelwe endaweni kwaye yongeza ukwanda kweendleko
Ngoko ngokusebenza, zombini izixhobo zisetyenziswe kuxhomekeke kwimeko ethile.
