Njira Yosankhira Fuse

1. Mphamvu Yamagetsi Yabwinobwino: Choyamba tiyenera kudziwa kukula kwa mphamvu yamagetsi yomwe imadutsa mu fuse mu dera lomwe likugwiritsidwa ntchito.

Kawirikawiri timayenera kukhazikitsa kuchepetsedwa pasadakhale, kenako kusankha motsatira mfundo iyi: ndiko kuti, mphamvu yamagetsi yanthawi zonse iyenera kukhala yocheperapo kuposa zomwe zapangidwa ndi mphamvu yamagetsi yoyesedwa ndi mphamvu yamagetsi yochepetsera.

2. Fuse Current: Mogwirizana ndi malangizo a UL, fuse iyenera kulumikizidwa mwachangu pa current yoyesedwa kawiri. Komabe, nthawi zambiri, kuti titsimikizire kuti fuse ndi yodalirika, tikupangira kuti fuse current ikhale yochulukirapo kuposa nthawi 2.5 kuposa current yoyesedwa.

Kuphatikiza apo, nthawi ya fuse ndi yofunika, komanso muyenera kuyang'ana chithunzi cha fuse chomwe chaperekedwa ndi wopanga kuti apereke chigamulo.

3. Volti Yotseguka ya Circuit: Volti yotseguka ya circuit nthawi zambiri iyenera kusankhidwa kuti ikhale yocheperapo kuposa voti yovoteledwa.

Mwachitsanzo, pamene fuse yokhala ndi voltage yovomerezeka ya dc24v ikugwiritsidwa ntchito mu ac100v circuit, n'zotheka kuyatsa kapena kuswa fuse.

4. Mphamvu yamagetsi yochepa: Mphamvu yayikulu yomwe timayendetsa pamene magetsi afupikitsidwa imatchedwa mphamvu yamagetsi yochepa. Pa ma fuse osiyanasiyana, mphamvu yamagetsi yochepetsedwa imatchulidwa, ndipo tiyenera kusamala kuti magetsi afupikitsidwe asapitirire mphamvu yamagetsi yocheperako posankha fuse.

Ngati fuse yokhala ndi mphamvu yochepa yosweka yasankhidwa, ikhoza kuswa fuse kapena kuyambitsa moto.

5. Mphamvu Yamphamvu: Mafunde (mafunde a pulse current waveform) owonera mphamvu yamagetsi amagwiritsidwa ntchito kuwerengera mphamvu yake pogwiritsa ntchito mtengo wa I2T (mtengo wa Joule integral). Mphamvu yamagetsi ndi yosiyana kukula ndi mafupipafupi, ndipo zotsatira pa fuse ndi zosiyana. Chiŵerengero cha mtengo wa i2t wa mphamvu yamagetsi ndi mtengo wa fuse i2t wa kugunda kamodzi chimatsimikizira kuchuluka kwa nthawi yomwe fuse imalimbana ndi mphamvu yamagetsi.
