Sezvatinoziva, chigadziro chekudzivirira chinogona kuparadza kana kusvika kusvika kumagumo ehupenyu kwenguva yakawanda nekuda kwekudzokidzwa kwechidiki, kubhururuka kwakasimba kwakasimudza kana kuramba kuchiwedzera. Uye kana chipfeko chekudzivirira chinopera, chinogona kuumba mamiriro emamiriro ezvinhu epfupi uye chinokonzera dambudziko rekuchengetedza muhurumende. Nokudaro zvakakodzera kudzivirirwa kwechigadziro chidimbu chinodikanwa kushanda pamwe chete nechikwata chekudzivirira.
Kune anowanzoita nezvemarudzi maviri overcurrent kuchengetedzwa zano rinoshandiswa pamwe SPD kuti negadziriro yeparutivi kudzivirirwa: redunhu mudariki uye fiyuzi. Saka, chii chavanoshandisa uye Cons inotevera?
Circuit Breaker
Advantages
- Inogona kuwedzerwa kushandiswa uye nokudaro kuderedza mari yekuchengetedza.
payakaipira
- Iva nekudonha kwakanyanya kwemagetsi kana uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchidzikisira iro reIDD,
Fuse
Advantages
- Zvishoma zvingaita kusashanda
- Pasi pfuti inodonha pakusvika ikozvino
- Chigadzirwa chacho pachacho chinodhura zvakanyanya kunyanya nokuda kwemukati pfupi pfupi parizvino mamiriro ezvinhu zvino
payakaipira
- Mushure mokushanda, fuse inofanira kuchinjwa uye saka kuwedzera mari yekuchengetedza
Saka mukuita, zvose zvishandiso zvinoshandiswa zvichienderana nemamiriro ezvinhu chaiwo.
