I. Kusanthula ndi njira yochizira ya zolakwika zomwe zimayambitsa
1. Pambuyo coil ndi mphamvu, contactor sachita kapena kuchita mwachibadwa
A. Dongosolo lowongolera koyilo lachotsedwa;onani ngati cholumikizira cholumikizira chathyoka kapena chomasuka.Ngati pali yopuma, m'malo lolingana waya.Ngati lotayirira, deftighten lolingana materminal.
b.Koyilo yawonongeka;kuyeza kukana kwa koyilo ndi multimeter.Ngati kukana kuli, m'malo mwa koyilo.
c.Relay yotenthetsera sichikubwezeretsedwanso pambuyo pakuchitapo kanthu.Gwiritsani ntchito zida za multimeter resistance kuti muyese mtengo wotsutsa pakati pa mfundo ziwiri zotsekera nthawi zonse za kutentha kwa kutentha, monga momwe zilili, kenaka dinani batani lobwezeretsanso kutentha.
d.The oveteredwa koyilo voteji ndi apamwamba kuposa mzere voltage.Sinthani koyilo ndinazolowera ulamuliro mzere voteji.
e.Lumikizanani ndi kuthamanga kwa kasupe kapena kutulutsa kuthamanga kwa masika ndikokulirapo.Sinthani kuthamanga kwa masika kapena kusintha kasupe.
Contact f, Batani lolumikizana kapena wothandizira wolumikizana nawo batani loyipa Chotsani cholumikizira kapena sinthani moyenerera.
Magulu a g ndi ma contact ndi akulu kwambiri.Sinthani mokulirapo
2. Pambuyo koyilo yazimitsidwa, cholumikizira sichidzatulutsidwa kapena kuchedwa kumasulidwa.
Yankho mogwirizana pa malekezero onse a koyilo.
b.Pamwamba pa cholumikizira cholumikizidwa ndi mafuta kapena mafuta pakatha nthawi yogwiritsira ntchito. Pukutani mafuta a dzimbiri pachimake, pachimake pamwamba payenera kukhala lathyathyathya, koma chisakhale chopepuka kwambiri, apo ayi ndizosavuta kuyambitsa kuchedwa.
c.Kulumikizana ndi anti-melting welding sikuyenda bwino.Pamene galimoto kapena mzere uli wamfupi, mphepo yamkuntho imapangitsa kuti touch.Mutu umakhala wotsekemera kwambiri ndipo sungathe kumasulidwa, ndipo kukhudzana kwasiliva koyera kumakhala kosavuta kusungunula kuwotcherera.Kulumikizana kwakukulu kwa AC contactor kuyenera kusankhidwa ndi siliva. -based alloy yokhala ndi kusungunuka kolimba komanso kukana kuwotcherera, monga siliva ndi chitsulo, siliva ndi faifi tambala, etc.
d.Konzani cholakwika cha wiring chowongolera molingana ndi chithunzi chowongolera.
Katatu, koyilo kutenthedwa, kuwotchedwa kapena kuonongeka.
A. Kuchuluka kwa mphete ndi mphamvu ya mphete zimaposa zofunikira zaumisiri za chinthucho. Bwezerani koyiloyo kuti mukhale ndi mafupipafupi ndi kupitilira mphamvu.
b.Pakatikati pake ndi wosafanana kapena kusiyana kwa mpweya ndi waukulu kwambiri. Tsukani pamtengo kapena sinthani pakati, ndikusintha koyiloyo.
The c, kuwonongeka kwa mawotchi, gawo loyenda ndilokhazikika.Konzani mbali zamakina ndikusintha koyilo.
d.Ngati malo ozungulira akutentha kwambiri, kapena kutsekereza koyilo kwawonongeka chifukwa mpweya wanyowa kapena mpweya wachita dzimbiri, m'malo mwa koyiloyo.
Chachinayi, phokoso la ma elekitiromu ndi lalikulu kwambiri.
A. Short circuit mphete imaswa ndikusintha mphete yachidule kapena pachimake
b.Kuthamanga kwa masika kukhudzana ndi kwakukulu, kapena ngati kukhudzana kumayenda kwambiri, sinthani kukhudzana kwa kasupe kapena kuchepetsa kupitirira.
c.Pini yolumikizira pakati pa zida zankhondo ndi gawo lamakina ndi lotayirira, kapena zomangira zomangira ndizomasuka.Ikani pini yolumikizira ndikumangitsa screw ya clamp.
Chachisanu, njira yayifupi yosinthira
A. The contactor amaunjikira fumbi kwambiri kapena timitengo ndi madzi ndi mpweya.Kuchuluka kwa mafuta kumapangitsa kuwonongeka kwa insulation.Cholumikizira chiyenera kutsukidwa nthawi zambiri, kusungidwa, choyera komanso chowuma.
Mu b.Ndi magetsi interlocking okha, kusintha nthawi ya chosinthika kutembenuka contactor ndi lalifupi kuposa kuyaka arc time.Add makina interlocks.
Mu c.Ngati arc hood imasweka, kapena mbali zolumikizana nazo zawonongeka ndi arc, kapena m'malo mwake zida zowonongeka.
Pamwambapa mavuto wamba mu ndondomeko kulankhulana kukhudzana ntchito, cholakwika anapanga kusanthula mwachidule, ndi kuika patsogolo yankho, mu ndondomeko yeniyeni ntchito adzakumana ndi mavuto ena, bola ngati tidziwa limagwirira kukhudzana kulankhulana, pamodzi ndi olemera zinachitikira. muzochita, mavuto ndi zolakwa adzakhala maphunziro ndi ofunika chidwi chanu!
Phokoso la cholumikizira cha AC
Kuthamanga AC contactor ndi phokoso kwambiri ndipo angathe kuchitidwa motere:
1. Ngati mphamvu yamagetsi yamagetsi ndi yosakwanira ndipo kuyamwa kwa electromagnet sikukwanira, tiyenera kuyesetsa kuwonjezera mphamvu ya dera loyendetsa ntchito.
2. Ngati mphamvu ya maginito imasonkhanitsidwa molakwika kapena kugwedezeka kapena makina opangira makinawo akugwedezeka, chitsulo chachitsulo sichikhoza kuphwanyidwa, zomwe zimapangitsa kuti phokoso likhalepo.
3. Dzimbiri pamwamba pa polar kapena thupi lachilendo (monga sikelo ya mafuta, fumbi, tsitsi, etc.) pakatikati, ndiye kuti pamwamba pake iyenera kutsukidwa.
4. Phokoso la ma elekitiroleti limapangidwa chifukwa cha kuthamanga kwambiri kwa masika, kotero nthawi zambiri sinthani kukhudzana kwa masika.
5. Pakakhala phokoso lochokera ku kuphulika kwa mphete yachidule, phokoso lapakati kapena lalifupi liyenera kusinthidwa.
6. Ngati mavalidwe apakati pamtengowo ndi ochulukirapo komanso osafanana, pachimake payenera kusinthidwa.
7. Dera lalifupi pakati pa kutembenuka, nthawi zambiri m'malo mwa koyilo.
Kuti mudziwe zambiri zaukadaulo, chonde tcherani khutu ku Jingdian Port.
