Chiyambi cha fuse yamagetsi

Mfundo ya fuse yamagetsi

Fuse yamagetsi ndi imodzi mwa ma fuse, yomwe imatanthauza chipangizo chamagetsi chomwe chimaphatikiza kusungunuka ndi kutentha komwe kumapangidwa kokha ndikuchotsa dera pamene mphamvu yamagetsi yapitirira mtengo woikika. Fuse ndi choteteza mphamvu yamagetsi chomwe chimapangidwa pogwiritsa ntchito kutentha komwe kumapangidwa kokha kusungunula kusungunuka pambuyo poti mphamvu yamagetsi yapitirira mtengo woikika kwa nthawi inayake, motero kusokoneza dera.

Mfundo yogwirira ntchito ya fuse ndi yosavuta I2R poyerekeza ndi nthawi. Mphamvu yamagetsi ikakwera, nthawi yolumikizira kapena kutsegula imakhala yochepa. Kutaya mphamvu kwa fuse kumafanana ndi sikweya ya mphamvu yamagetsi kudzera mu fuse. Mphamvu ikagwiritsidwa ntchito kwambiri, fuse imaphulika. Izi zimagwiranso ntchito pa zingwe zotetezedwa ndi fuse. Ngati kutentha komwe kwapangidwa kupitirira kutentha komwe kwatha, kutentha kwa fuse kumawonjezeka. Kutentha kukakwera kufika pamalo osungunuka a fuse ya fuse, fuse imaphulika, ndiko kuti, dera lidzatsekedwa kuti litetezedwe.

Ma fuse amagwiritsidwa ntchito kwambiri m'makina ogawa mphamvu zamagetsi okwera komanso otsika komanso makina owongolera komanso zida zamagetsi. Monga choteteza chafupikitsa komanso overcurrent, ndi chimodzi mwa zida zodzitetezera zomwe zimagwiritsidwa ntchito kwambiri.

Kugawa ma fuse amphamvu

Ma fuse amphamvu ndi gawo la ma fuse (ma fuse), amatha kugawidwa m'ma fuse oteteza semiconductor, ma fuse a DC, ma fuse apadera, ma fuse ogwiritsidwa ntchito nthawi zonse ndi ma fuse olumikizira.

Makhalidwe a kapangidwe ka fuse yamagetsi

Kapangidwe ka fuse yamagetsi ndi kofanana ndi ka fuse. Kapangidwe kake kamakhala ndi kusungunuka, chipolopolo ndi chithandizo, zomwe kusungunuka ndiye chinthu chofunikira kwambiri chowongolera mawonekedwe a kusakanikirana. Zinthu, kukula ndi mawonekedwe a kusungunuka kumatsimikizira mawonekedwe a kusakanikirana. Zinthu zosungunuka zimagawidwa m'magulu awiri: malo otsika osungunuka ndi malo okwera osungunuka. Zinthu zochepa zosungunuka monga lead ndi lead alloys zimakhala ndi malo otsika osungunuka ndipo ndizosavuta kuphatikiza. Chifukwa cha kukana kwawo kwakukulu, kukula kwa kusungunuka kwa gawo lopingasa ndi kwakukulu, ndipo nthunzi yambiri yachitsulo imapangidwa panthawi yophatikiza. Ndi yoyenera kokha kuphatikiza ndi chipangizo chopanda mphamvu yosweka. Zipangizo zambiri zosungunuka monga mkuwa ndi siliva zimakhala ndi malo okwera osungunuka ndipo sizosavuta kuphatikiza, koma chifukwa cha kukana kwawo kochepa, zimatha kupangidwa kukhala magawo ang'onoang'ono opingasa kuposa malo otsika osungunuka osungunuka, ndikupanga nthunzi yochepa yachitsulo ikaphatikizidwa, yomwe ndi yoyenera malo okwera osweka. Mawonekedwe a kusungunuka amagawidwa m'mitundu iwiri: ulusi ndi riboni. Kusintha mawonekedwe a gawo losinthika kumatha kusintha kwambiri mawonekedwe a kusakanikirana kwa fuse.
