Isakhiwo, imigaqo-siseko kunye nokukhethwa kwe-fuse

I-fuse, idla ngokuhlala njenge-inshurensi, yenye yezona zixhobo zilula zombane. Xa izixhobo zombane kwigridi yamandla okanye ngaphezulu kwesekethe okanye isekethe emfutshane, inokunyibilika kwaye inqande isiphatho se-grid kunye negunya lombane, kwaye lithintele ukusasazeka kwengozi.

Enye, imodeli yefuse

Ileta yokuqala imele i-fuse.

Ileta yesibini m ayithethi ukuba akukho kupakisha uhlobo lwetyhubhu evaliweyo;

T kuthetha ukupakisha ityhubhu evaliweyo;

L kuthetha ukuba spiral;

S imele ifomu ekhawulezileyo;

C imele i-porcelain faka;

Z imele ukuzithemba.

Okwesithathu yikhowudi yoyilo ye-fuse.

Okwesine imele i-fuse.

Ezimbini, ukwahlulahlula

Ngokwendlela, i-fus inokwahlulwa yangamacandelo amathathu: Uhlobo oluvulekileyo, uhlobo oluvaliweyo oluvaliweyo kunye nohlobo oluvaliweyo.

1. Uhlobo lokuvula

Xa inyibilikisi ayiyithinteli idangatye le-ARC kwaye inyibilike inyibilikisi, ilungele kuphela isisikizi esifutshane okwangoku ayisiyonto isetyenziswayo, le fuse ihlala isetyenziswa ngokudibeneyo.

I-2. I-fuse efakwe kuyo

I-fuse ifakwe kwityhubhu, kwaye enye okanye zombini iziphelo zetyhubhu zivuliwe. Xa i-fuse inyibilikisiwe, idangatye le-Arc kunye nentsimbi inyibilikisa amasuntswana athatyathwa kwindawo ethile, enciphisa ukulimala kwabasebenzi, kodwa ayikhuselekanga ngokwaneleyo.

3. I-fuse efakwe

I-fuse ifakwe ngokupheleleyo kwiqokobhe, ngaphandle kwe-arc ekrwada, kwaye ayiyi kubangela ingozi kwinxalenye ephilayo edlalayo i-Arc kunye nabasebenzi abakufuphi.

Isithathu, isakhiwo seFuse

I-fuse iqokelelwe ikakhulu ngokunyibilikisi kunye ne-fuse tube okanye i-fuse umniniyo olwenziwe kuyo.

I-1.melt yinxalenye ebalulekileyo ye-fuse, idla ngokuba yi-silk okanye iphepha. Zimbini iintlobo zezixhobo ezinyibilikayo, enye iphantsi kwezinto eziphantsi zokunyibilika, ezinjengokukhokela, i-zinc, itin kunye ne-tin-khonkco; Olunye luphantsi lwamanqanaba aphezulu, njengesilivere nobhedu.

2.I-tube enyibilikayo yiqokobhe elikhuselayo le-iltivel, kwaye inefuthe lokucima i-ARC xa inyibilikisiwe.

Ezine, i-fuse parameters

Iiparamitha zefuse zibhekisa kwiiparameter ze-fuse okanye umnini we-fuse, hayi iiparameter zelitye.

I-1. Ndinyibilike iiparamitha

I-MALT ineeparamitha ezimbini, i-rating yangoku kunye nokuntywila okwangoku. I-RAUTE YONYAKA KUPHELA UKUBA IXABISO LWEZIXOKI NGOKUQINISEKILEYO NGEXESHA LOKUGQIBELA ixesha elide ngaphandle kokophula. I-fuse yangoku ihlala iphindwe kabini, ngokubanzi ngokunyibilikisa i-1.3 amaxesha okuqhutywa kwangoku, kufuneka ityhutywe ngaphezulu kweyure enye; 1.6 amaxesha, kufuneka ifudukele kwiyure enye; Xa i-fuse yangoku ifikile, i-fuse yaphukile emva kwe-30 ~ 40 imizuzwana; Xa i-9 ~ Izihlandlo ezili-10 ezilinganisiweyo kufikelelwe okwangoku, ukunyibilika kufuneka kwaphule kwangoko. I-MALT inomzimba wokukhusela ixesha elininzi, okhukuliseko lwangoku lokuhambahamba ngokunyibilika, elifutshane ixesha elinqabileyo.

I-2. Imibhobho ye-welding

I-fuse ineeparamitha ezintathu, ezizezinye i-voltage, ikaliwe zangoku nezika amanzi.

1) I-Voltage eDityanisiweyo iphakanyisiwe kwi-angle ye-ARC egxothiweyo. Xa i-voltage yokusebenza ye-fuse inkulu kune-voltage enqwenelekayo, kunokubakho ingozi yokuba i-ARC ayinakucinywa xa inyibilikisiwe.

2) Ityhubhu yangoku yetyhubhu ye-molten lixabiso langoku elimiselwe liqondo elivumelekileyo letyhubhu ye-molten ixesha elide, kodwa ityhubhu ye-molten inokuthi ingabi ngaphezu kwetyhubhu ye-molten tube.

3) Umthamo osikiweyo yelona xabiso liphezulu elinokunqunyulwa xa i-fuse ikhutshiwe kwityala lesekethe kwi-voltage engaphakathi.

Isihlanu, imigaqo yokusebenza ye-fuse

Inkqubo ye-fuse ye-fuse iqulathe yahlulahlulwe yaba ngamanqanaba amane:

1. I-MART i-MART ikwisekethe, kwaye umthwalo ohamba ngokuhamba ngokunyibilika. Ngenxa yefuthe le-shirmal yangoku liya kwenza ukuba iqondo lokushisa linyibilike, xa kusenzeka isiphaluka okanye isiphaluka esifutshane, isekethe elifutshane elifutshane liya kwenza ukunyibilika kobushushu obugqithisileyo kunye nokufikelela kubushushu obugqithisileyo. Ukuphakama kwangoku, ngokukhawuleza amaqondo obushushu anyuka.

2. Ukunyibilikisa kuya kunyibilika kwaye kukhutshelo kwi-vapor yentsimbi emva kokufikelela kubushushu bokunyibilika. Ukuphakama kwangoku, ixesha elifutshane ixesha lokunyibilika.

3. Umzuzu unyibilike, kukho isithuba esincinci esincinci kwisekethe, kwaye okwangoku ukuphazamiseka ngequbuliso. Kodwa esi sithuba sincinci siqhekezwe ngokukhawuleza yi-voltage yesekethe, kwaye i-ARC yombane ivelisiwe, ethi idibanise isekethe.

4. Emva kokuba i-ARC yenzeka, ukuba amandla ayancipha, uya kuyiphakamisa ngokwandiswa komsantsa we-fuse, kodwa kufuneka ixhomekeke kumanyathelo afundelayo efundela xa amandla amakhulu. Ukwenzela ukunciphisa ixesha lokucima i-ARC kwaye kwandise amandla okuqhekeza, amandla amakhulu amasu axhotyiswe ngamanyathelo afanelekileyo e-ArC. Ukukhululeka komthamo wokupheliswa kwe-Arc, okhawulezayo ukuba i-ARC icinyiwe, kwaye ukukhulu kwesekethe emfutshane kunokwaphuka yi-fuse.

Isithandathu, ukhetho lwe-fuse

1. Khetha i-fus ngamanqanaba evolthi ehambelanayo ngokwe-voltage yegridi yamandla;

2. Khetha i-fus enezakhono zokuqhekeza ezihambelanayo ngokweyona nto iphezulu

3, i-fuse kwisekethe yemoto yokuKhuselo kwisekethe, ukwenzela ukuthintela imoto kwinkqubo yokuqalisa i-fuse, kwimoto enye, imali enqwenelekayo ayithintelwanga kwi-1.5 ~ Ngeemotor ezininzi, i-melt inyibilikisiwe yangoku ayisayi kuba ngaphantsi kwe-1.5 ~ 2.5 amaxesha okhangelwe umthwalo ophezulu wemoto eninzi yeMotolo.

I-4. Ukukhusela isekethe okanye ukutya kombane kunye neminye imithwalo, imali eqingqiweyo ye-melt kufuneka ilingane okanye ibe mkhulu kancinci kunexesha lomthwalo.

5. Xa usebenzisa i-fuse ukukhusela imigca, i-fuse kufuneka ifakwe kumgca wesigaba ngasinye. Akuvumelekanga ukufaka i-fuse kumgca ongathathi hlangothi kwiSigaba seSigaba seSibini seSigaba seSigaba seSigaba seSigaba seZibini okanye isigaba seSithathu se-Wire, kuba ikhefu le-hlangone liza kubangela ukungalingani kwe-voltage, enokutshisa izixhobo zombane. Kwimigca yesigaba esinye ebonelelweyo yigridi yoluntu, i-fuse kufuneka ifakwe kwimigca engathathi hlangothi, ngaphandle kwe-gud iyonke yegridi.

6. Onke amanqanaba ee-fuse kufuneka asebenzisane xa esebenzisa, kwaye ukhawulelwe okwangoku kufuneka kube mncinci kunelo kwinqanaba eliphezulu.
