Indlela Yokukhetha I-Fuse

1. Ugesi Ojwayelekile: Okokuqala kumele sazi usayizi wamandla ojwayelekile ogeleza nge-fuse esesekethe esetshenziswayo.

Ngokuvamile kufanele simise ukwehla kusenesikhathi, bese sikhetha ngokuvumelana nomgomo olandelayo: okungukuthi, ugesi ojwayelekile kumele ube ngaphansi komkhiqizo wamandla alinganiselwe kanye ne-coefficient yokunciphisa.

2. I-Fuse Current: Ngokuhambisana nezincazelo ze-UL, i-fuse kufanele ihlanganiswe ngokushesha ku-current elinganisiwe kabili. Nokho, ezimweni eziningi, ukuze kuqinisekiswe i-fuse ethembekile, sincoma ukuthi i-fuse current ibe ngaphezu kwe-current elinganisiwe izikhathi ezingu-2.5.

Ngaphezu kwalokho, isikhathi se-fuse sibalulekile, kodwa futhi kumele sibheke umdwebo wesici se-fuse onikezwe umenzi ukuze enze isinqumo.

3. I-Open Circuit Voltage: i-open circuit voltage ngokuvamile kufanele ikhethwe ibe ngaphansi kwe-voltage ekaliwe.

Isibonelo, uma kusetshenziswa i-fuse ene-voltage elinganisiwe ye-dc24v kusekethe ye-ac100v, kungenzeka ukuthi ivuthe noma iphule i-fuse.

4. Ugesi we-short-circuit: Inani lamanje eliphakeme kakhulu esilihambayo lapho isekethe i-short-circuit libizwa ngokuthi ugesi we-short-circuit. Kuma-fuse ahlukahlukene, umthamo we-rating break ucacisiwe, futhi kumelwe siqaphele ukuthi singawenzi ugesi we-short-circuit udlule umthamo wesekethe olinganiselwe lapho sikhetha i-fuse.

Uma kukhethwa i-fuse enekhono elincane lesekethe eliphukile, ingase iphule i-fuse noma ibangele umlilo.

5. Ugesi Womthelela: I-waveform (i-pulse current waveform) yokubuka ugesi womthelela isetshenziselwa ukubala amandla ayo kusetshenziswa inani le-I2T (inani elihlanganisiwe le-Joule). Ugesi womthelela uhlukile ngobukhulu kanye nemvamisa, futhi umphumela ku-fuse uhlukile. Isilinganiso senani le-i2t lamandla omthelela nenani le-fuse i2t le-pulse eyodwa sinquma inani lezikhathi lapho i-fuse imelana khona nogesi womthelela.
