I. Uhlalutyo kunye nendlela yonyango yezizathu ze-fault phenomenon
1. Emva kokuba ikhoyili inikwe amandla, umnxibelelwano akenzi okanye enze ngokungaqhelekanga
A. I-coil control circuit iyanqanyulwa;jonga ukuba i-terminal yocingo yaphukile okanye ikhululekile.Ukuba kukho ikhefu, buyisela ucingo oluhambelanayo.
b.Ikhoyili yonakele;ukulinganisa ukuchasana kwekhoyili nge-multimeter.Ukuba ukuxhathisa, buyisela ikhoyili.
c.I-relay ye-thermal ayilungiswanga kwakhona emva kwesenzo.Sebenzisa i-multimeter yokumelana nesixhobo ukulinganisa ixabiso lokuchasana phakathi kweendawo ezimbini zokuvala rhoqo kwi-heat relay, njengokuba kunjalo, uze ucinezele iqhosha lokusetha kwakhona kwi-relay relay.
d.I-voltage ye-coil elinganisiweyo iphezulu kune-voltage yomgca.Shintsha ikhoyili eguqulelwe kwi-voltage yolawulo lomgca.
e.Qhagamshelana noxinzelelo lwentwasahlobo okanye ukukhulula uxinzelelo lwentwasahlobo lukhulu kakhulu.Lungisa uxinzelelo lwentwasahlobo okanye utshintshe intwasahlobo.
Qhagamshelana f, Iqhosha lomfowunelwa okanye umfowunelwa oncedisayo iqhosha elibi Coca umfownelwa okanye buyisela ngokufanelekileyo.
I-g kunye nabafowunelwa zikhulu kakhulu. Lungisa umphezulu we-touch
2. Emva kokuba ikhoyili ivaliwe, umnxibelelanisi akayi kukhululwa okanye alibazise ukukhululwa.
A. Ikholamu kwinkqubo yemagnethi ayinasikhewu somoya, kwaye indawo eseleyo yimagnethi inkulu kakhulu. Susa indawo yepali kumphezulu wemagnethi oseleyo ukuze umsantsa ube yi-0.1~0.3mm, okanye ube ne-0.1uF capacitor. ngokunxuseneyo kuzo zombini iziphelo zekhoyili.
b.Umphezulu we-core contact core i-oyile okanye i-greasy emva kwexesha lokusetyenziswa.Sula igrisi ye-rust kwi-core surface, i-core surface kufuneka ibe tyaba, kodwa ingabi lula kakhulu, ngaphandle koko kulula ukubangela ukukhululwa kokulibaziseka.
c.Ukusebenza kwe-welding anti-melting akubi kakuhle.Xa i-motor okanye umgca ufutshane, i-high current yenza i-touch.Intloko igxininiswe ngokuqinileyo kwaye ayikwazi ukukhutshwa, kwaye i-contact yesilivere ecocekileyo ilula ukunyibilikisa i-welding.Uqhagamshelwano oluphambili lwe-AC contactor kufuneka lukhethwe ngesilivere. -i-alloy esekelwe ngokunyibilika okunamandla kunye nokuchasana kwe-welding, njengesilivere kunye nentsimbi, isilivere kunye ne-nickel, njl.
d.Lungisa impazamo yolawulo lwe-wiring ngokomzobo wokulawula iintambo.
Isithathu, i-coil overheating, itshiswe okanye yonakele.
A. Ukuphindaphinda kunye nomlinganiselo wamandla weringi udlula iimfuno zobugcisa zemveliso.Buyisela ikhoyili ngokuphindaphindiweyo kunye nokuqhubekeka kwamandla.
b.Umphezulu ongundoqo awulingani okanye umsantsa womoya wekholomu mkhulu kakhulu.Coca umphezulu wepali okanye ulungise undoqo, kwaye ubeke indawo ikhoyili.
I-c, umonakalo womatshini, inxalenye yentshukumo ibambekile.Lungisa iinxalenye zoomatshini kwaye ubuyisele ikhoyili.
d.Ukuba ubushushu be-ambient buphezulu kakhulu, okanye ukugquma ikhoyili konakalisiwe ngenxa yokuba umoya umanzi okanye irhasi inomhlwa, buyisela ikhoyili.
Okwesine, ingxolo ye-electromagnetic inkulu kakhulu.
A. Ikhefu elifutshane lesekethe ikhefu kwaye ithathe indawo yesekethe emfutshane okanye ingundoqo
b.Uxinzelelo lwentwasahlobo yoqhagamshelwano lukhulu kakhulu, okanye ukuba umnxibelelwano uhamba kakhulu, lungisa uxinzelelo loqhagamshelwano lwasentwasahlobo okanye unciphise ukugqithisa.
c.Iphini lokuqhagamshela phakathi kwe-armature kunye nenxalenye yomatshini ikhululekile, okanye i-clamp screw ikhululekile.Faka iphini lokuqhagamshela kwaye uqinise isikrufu sokubamba.
Isihlanu, enye isekethe emfutshane
A. Umnxibelelanisi uqokelela uthuli oluninzi okanye iintonga ngamanzi kunye negesi.Isikali seoli senza umonakalo wokugquma.I-contactor kufuneka ihlanjululwe rhoqo, igcinwe, icoceke kwaye yome.
Kwi b.Ngokudibanisa kombane kuphela, ixesha lokutshintshwa kwe-contactor yokuguqula ukuguqulwa lifutshane kunexesha le-arc yokutshisa.Yongeza i-mechanical interlocks.
Kwi-c.Ukuba i-arc hood iyaphuka, okanye iindawo zokudibanisa zonakaliswe yi-arc, okanye zitshintshe iindawo ezonakalisiweyo.
Ngaphezulu kweengxaki eziqhelekileyo kwinkqubo yokusebenza koqhagamshelwano lonxibelelwano, impazamo yenza uhlalutyo olufutshane, kwaye ibeke phambili isisombululo, kwinkqubo yokusebenza yokwenene iya kuhlangabezana nezinye iingxaki, okoko sisazi kakuhle indlela yoqhagamshelwano lonxibelelwano, kudityaniswe namava azizityebi. ekusebenzeni, iingxaki kunye neempazamo ziya kuba uqeqesho lufanelekile ingqalelo yakho!
Akukho ngxolo ye-AC contactor
Ukubaleka AC contactor ingxolo kakhulu kwaye ingaphathwa ngolu hlobo lulandelayo:
1. Ukuba i-voltage yonikezelo lwamandla ayanelanga kwaye ukufunxa i-electromagnetic akwanele, kufuneka sizame ukwandisa umbane wesiphaluka sokusebenza.
2. Ukuba inkqubo yamagnetic idityaniswe ngokungafanelekanga okanye ishukunyiswa okanye umatshini womatshini unamathele, intsimbi yentsimbi ayinakunqunyulwa, ibangele ingxolo.Le nkqubo kufuneka ilungiswe ukuchonga nokuphelisa izizathu zokuguquguquka.
3. I-polar surface rust okanye umzimba wangaphandle (njenge-oyile yesikali, uthuli, iinwele, njl.) kwindawo engundoqo, ngoko umgangatho ongundoqo kufuneka ucocwe.
4. Ingxolo ye-electromagnetic yenziwa ngenxa yoxinzelelo olugqithisileyo loqhagamshelwano lwasentwasahlobo, ngoko ke ngokuqhelekileyo uhlengahlengiso loxinzelelo lwentwasahlobo yoqhagamshelwano.
5. Kwimeko yengxolo evela kwi-short circuit ring fracture, i-core okanye i-short circuit ring kufuneka itshintshwe.
6. Ukuba i-core pole surface wear igqithise kwaye ayilingani, undoqo kufuneka utshintshwe.
7. Isiphaluka esifutshane phakathi kokujika, ngokuqhelekileyo sithatha indawo yekhoyili.
Ngolunye ukhokelo lobugcisa, nceda unikele ingqalelo kwi-Jingdian Port.
