Indlela yoKhetho yeFuse

1.Normal yangoku: Kuqala kufuneka sazi ubungakanani obuqhelekileyo ngoku obuhamba ngefuse kwisekethe esetyenzisiweyo.

Ngokwesiqhelo kufuneka sibeke ukuncitshiswa kwangaphambili, emva koko sikhethe ngokwalo mgaqo ulandelayo: Oko kukuthi, imeko yesiqhelo yangoku kufuneka ibe ngaphantsi kwemveliso yexabiso langoku kunye nomlinganiso wokunciphisa.

2.Fuse yangoku: Ngokuhambelana neenkcukacha ze-UL, i-fuse kufuneka ifakwe ngokukhawuleza kwinqanaba elilinganisiweyo eliphindwe kabini. Kwiimeko ezininzi, nangona kunjalo, ukuze kuqinisekiswe i-fuse ethembekileyo, sicebisa ukuba i-fuse yangoku kufanele ukuba ibe ngaphezulu kwamaxesha ama-2,5 amaxesha akhoyo ngoku.

Ukongeza, ixesha le fuse libalulekile, kodwa kufuneka libhekise kumzobo wefusethi enikezwe ngumenzi ukwenza isigwebo.

3.Vula i-Voltage yeSekethe: ivolthi yesekethe evulekileyo kufuneka ikhethwe ngokubanzi ukuba ibe ngaphantsi kwamandla ombane alinganisiweyo.

Umzekelo, xa i-fuse enevolthi ekaliwe ye-dc24v isetyenziswa kwisekethe ye-ac100v, kunokwenzeka ukutshaya okanye ukwaphula i-fuse.

I-4.Short-circuit current: Elona xabiso liphezulu langoku sihamba ngalo xa isekethe lifutshane-libizwa ngokuba kukufutshane-kwisekethe yangoku. Kwiifyuzi ezahlukileyo, amandla okuphumla amiselweyo achaziwe, kwaye kufuneka silumke singenzi isiphaluka esikhoyo ngoku sidlule kumandla wesekethe alinganisiweyo xa ukhetha i-fuse.

Ukuba kukhethwa i-fuse enamandla amancinci esekethe, inokuphula i-fuse okanye ibangele umlilo.

I-5.Impact yangoku: I-waveform (i-pulse current waveform) yokujonga ifuthe langoku isetyenziselwa ukubala amandla ayo kusetyenziswa ixabiso le-I2T (ixabiso le-Joule). Impembelelo yangoku yahlukile kubungakanani kunye nokuhamba rhoqo, kwaye umphumo kwifuse uhlukile. Umlinganiselo wexabiso le-i2t yefuthe langoku kwi-fuse i2t yexabiso le-pulse enye limisela inani lamaxesha le fuse elichasene nefuthe langoku.
