Fuse, inowanzozivikanwa seinishuwarenzi, ndechimwe chezvinhu zviri nyore kudzivirira zvemagetsi. Kana midziyo yemagetsi iri mugetsi remagetsi kana redunhu kuwandisa kana kupfupika kwedunhu, inogona kunyunguduka nekupwanya dunhu pachayo, kudzivirira gidhi remagetsi uye kukuvara kwemidziyo yemagetsi nekuda kwekupisa kwesimba remagetsi uye simba remagetsi, uye kudzivirira kupararira kwemagetsi. tsaona.
Imwe, modhi yefuse
Vara rekutanga R rinomirira fuse.
Tsamba yechipiri M inoreva kuti hapana kurongedza yakavharwa chubhu mhando;
T zvinoreva packed closed tube type;
L zvinoreva spiral;
S inomirira chimiro chekukurumidza;
C inomirira porcelain insert;
Z inomirira self-duplex.
Yechitatu ndiyo kodhi yekugadzira yefuse.
Yechina inomiririra yakayerwa ikozvino yefuse.
Chechipiri, kupatsanurwa kwemafusi
Zvinoenderana nechimiro, fuse inogona kukamurwa muzvikamu zvitatu: yakavhurika mhando, semi-yakavharwa mhando uye yakavharwa mhando.
1. Vhura mhando fuse
Kana iyo yakanyunguduka isingadzikisire arc murazvo uye simbi inonyungudutsa zvimedu ejection mudziyo, yakakodzera chete kuburitsa pfupi dunhu ikozvino haisi nguva huru, iyi fuse inowanzoshandiswa pamwe chete nebanga switch.
2. Semi-yakavharwa fuse
Iyo fuse inoiswa muchubhu, uye imwe kana migumo miviri yechubhu inovhurwa. Kana iyo fuse yakanyungudutswa, iyo arc murazvo uye simbi yakanyunguduka zvimedu zvinoburitswa mune imwe nzira, izvo zvinoderedza kumwe kukuvadzwa kune vashandi, asi haisati yakachengeteka zvakakwana uye kushandiswa kunogumira kune imwe nhanho.
3. Fuse yakavharwa
Iyo fuse yakavharirwa zvachose mugoko, isina arc ejection, uye haizokonzerese njodzi kune iri pedyo mhenyu chikamu chinobhururuka arc nevashandi vepedyo.
Chetatu, fuse chimiro
Iyo fuse inonyanya kuumbwa nekunyunguduka uye fuse chubhu kana fuse inobata iyo inonyungudika inoisirwa.
1.Kunyunguduka chikamu chakakosha chefuse, chinowanzoitwa silika kana pepa. Kune marudzi maviri emidziyo yakanyunguduka, imwe ishoma inonyungudika zvinhu, zvakaita se lead, zingi, tin uye tin-lead alloy; Imwe yacho ndeye yakakwirira kunyungudika zvinhu, senge sirivheri nemhangura.
2.The melt tube ndiyo ganda rekudzivirira rekunyunguduka, uye rine simba rekudzima arc kana iyo yakanyungudutswa yakasanganiswa.
Zvina, fuse parameters
Maparamendi efiyuzi anoreva maparamendi efuse kana fuse holder, kwete maparamendi ekunyunguduka.
1. Sungunusa parameters
Iyo melt ine ma parameter maviri, yakayerwa ikozvino uye fusing ikozvino. Rated current inoreva kukosha kweizvino inopfuura nepafuse kwenguva refu isingatyoki. Iyo fuse ikozvino inowanzoita zvakapetwa kaviri iyo yakayerwa ikozvino, kazhinji kuburikidza nekunyunguduka ikozvino i1.3 nguva yakayerwa ikozvino, inofanira kusanganiswa muinopfuura awa imwe; 1.6 nguva, inofanira kusanganiswa mukati meawa imwe; Kana iyo fuse ikozvino yasvika, iyo fuse inoputswa mushure me30 ~ 40 masekonzi; Kana 9 ~ 10 nguva iyo yakatemerwa ikozvino yasvika, iyo inonyunguduka inofanira kubvaruka ipapo. Iyo yakanyunguduka ine hunhu hwekudzivirira hwenguva inverse, iyo yakakura ikozvino inoyerera kuburikidza nekunyunguduka, iyo ipfupi nguva yekusanganisa.
2. Welding pipe parameters
Iyo fuse ine ma parameter matatu, anoti rated voltage, rated current uye cut-off capacity.
1) Iyo yakayerwa voltage inokurudzirwa kubva kuAngle yekudzima arc. Apo simba rekushanda re fuse rakakura kudarika chiyero chemagetsi, panogona kuva nengozi yokuti arc haigoni kudzimwa kana kunyunguduka kwaputsika.
2) Iyo yakatemerwa ikozvino yechubhu yakanyungudutswa ndiyo yazvino kukosha inotarwa neinobvumidzwa tembiricha yechubhu yakanyungudutswa kwenguva yakareba, saka chubhu yakanyungudutswa inogona kutakurwa nemagiredhi akasiyana eyakayerwa ikozvino, asi yakayerwa ikozvino yechubhu yakanyungudutswa inogona kutakurwa. kwete yakakura kudarika yakayerwa ikozvino yechubhu yakanyungudutswa.
3) Kuchekwa-kurebesa simba ndiyo yakanyanya kukosha ikozvino inogona kugurwa kana fuse ichibviswa kubva pakukanganisa kwedunhu pane yakayerwa voltage.
shanu, nheyo yekushanda ye fuse
Iyo fusing process ye fuse yakakamurwa kuita nhanho ina:
1. Iyo yakanyunguduka iri munhevedzano mudunhu, uye mutoro wezvino unoyerera kuburikidza nekunyunguduka. Nekuda kwekupisa kweiyo yazvino kuchaita kuti kunyunguduka kwekushisa kusimuke, kana dunhu rakaremerwa kana dunhu diki rikaitika, iyo yakawandisa ikozvino kana pfupi yedunhu ikozvino ichaita kuti kunyungudika kwakanyanyisa kupisa uye kusvika pakunyungudika. Iyo yakakwirira ikozvino, iyo inokurumidza kuwedzera tembiricha.
2. Iyo inonyunguduka ichanyunguduka uye ichibuda mumhute yesimbi mushure mekusvika tembiricha yekunyungudika. Iyo yakakwirira ikozvino, iyo ipfupi nguva yekunyunguduka.
3. Nguva iyo inonyunguduka, pane chidimbu chekudzivirira mukati medunhu, uye ikozvino inokanganiswa kamwe kamwe. Asi iyi gaka diki rinobva raputswa nemagetsi edunhu, uye arc yemagetsi inogadzirwa, iyo inozobatanidza dunhu.
4. Mushure mokunge arc ichiitika, kana simba racho richiderera, rinozvidzima nekuwedzera kwegeji refuse, asi rinofanira kuvimba nezviyero zvekudzima zvefuse kana simba rakakura. Kuti uderedze iyo arc yekudzima nguva uye kuwedzera kugona kwekupwanya, iwo mafiyuzi makuru emagetsi akashongedzerwa akakwana arc ekudzima matanho. Iyo yakakura iyo arc yekudzima simba ndeye, nekukurumidza iyo arc inodzimwa, uye yakakura iyo pfupi yedunhu ikozvino inogona kuputswa nefuse.
Nhanhatu, kusarudzwa kwefuse
1. Sarudza mafiyuzi ane mazinga evoltage anoenderana nemagetsi grid voltage;
2. Sarudza mafizi ane anopindirana kutyora kugona zvinoenderana nehupamhi hwekutadza ikozvino hunogona kuitika muhurongwa hwekugovera;
3, iyo fuse mumotokari yedunhu rekudzivirira kupfupi kwedunhu, kuitira kudzivirira mota mukutanga fuse, kune imwe mota, iyo yakayerwa ikozvino yekunyunguduka haifanirwe kuve isingasviki 1.5 ~ 2.5 nguva yakatarwa ikozvino. yemota; Kune akawanda mota, iyo yakazara yakanyunguduka yakayerwa ikozvino haizove isingasviki 1.5 ~ 2.5 nguva yakarongerwa yazvino yeyakanyanya simba mota pamwe neyakaverengerwa mutoro wazvino weasara emota.
4. Nokuda kwekudzivirirwa kwenguva pfupi kwekuvhenekera kana moto wemagetsi nemimwe mitoro, iyo yakarongerwa ikozvino yekunyunguduka inofanira kuenzana kana kuti zvishoma kudarika yakarongwa ikozvino yemutoro.
5. Paunenge uchishandisa fuse kuchengetedza mitsetse, fuse inofanira kuiswa pamutsara wechikamu chimwe nechimwe. Zvinorambidzwa kuisa fuse pamutsara usina kwazvakarerekera mune maviri-chikamu chetatu-waya kana matatu-chikamu mana-waya redunhu, nekuti kwaakarerekera mutsara kutyora kunokonzera voltage kusaenzana, izvo zvinogona kupisa midziyo yemagetsi. Pamitsetse ye-single-phase inopihwa negridi yeruzhinji, fuse inofanirwa kuiswa pamitsetse isina kwayakarerekera, isingabatanidzi iyo yakazara fuse yegridi.
6. Mazinga ese emafusi anofanirwa kubatirana pamwe chete kana ashandiswa, uye chiyero chezvino chekunyunguduka chinofanira kunge chiri chidiki pane chepamusoro.
