Basa reKuzvidzorera reFuse

Kana kukundikana kwe overcurrent overheating kwabviswa, chinhu che fuse chinogona kudzoserwa otomatiki kune low resistance state. Izvi zvinodzivirira shanduko dzekuchengetedza uye mamiriro ekuvhura nekuvhara ezvindori zvinotevedzana zvinogona kukonzera kukuvara kwecircuit. Nekuda kwekugadzirwa kwayo kwakakosha, reset fuse ine mabasa maviri ekudzivirira overcurrent ne overheating pamwe ne automatic recovery. Iyo self-recovery fuse inogadzirwa nemusanganiswa wema polymer nezvinhu zvinofambisa. Iyo polymer reset fuse ine polymer resin matrix uye conductive particle yakapararira mairi. Mumamiriro ezvinhu akajairwa, conductive particles mu resin matrix inoumba chain conductive pathway, uye polymer inogona kugadzirisa fuse kuti ipe low impedance (a). Kana magetsi akaitika mucircuit, kupisa kunogadzirwa ne high current inoyerera kuburikidza ne polymer kunogona kugadzirisa fuse kunoita kuti vhoriyamu ye polymer resin substrate ikure, ichicheka chain conductive pathway yakagadzirwa ne conductive particles, zvichikonzera kuwedzera nekukurumidza kwe impedance saka, polymer inogona kugadzirisa fuse inogona kutamba overcurrent protection effect pacircuit (b). Mushure mekunge kukundikana kwabviswa, resin inotonhorera uye inosimbisa zvakare, vhoriyamu inoderera, zvidimbu zvinofambisa mhepo zvinoumba nzira yekufambisa mhepo zvakare, uye polymer inogona kudzorera fuse ku impedance yakaderera. Kana ichienzaniswa nemafuse echinyakare, ine zvakanakira zvekudzokorora pachayo, diki uye yakasimba.
