AC contactor inoshandiswa zvakanyanya mu low-voltage circuit, imhando yekushandiswa kwakachengeteka, nyore kutonga, yakawanda uye yakawanda yezvigadzirwa zvemaindasitiri. anopfuura mamiriyoni zana emamita, ayo anoshanda emagetsi emagetsi system mukukweva kwesimba rinoshanda rekushandisa pakati pe8w-100w.Iyo reactive simba rinoshandiswa riri pakati pemabhiriji akawanda nemazana mabhiri.Kugoverwa kwesimba rinoshanda rinopedzwa rinenge 65% ~ 75% iron core, short circuit ring 25% ~ 30%, 3% ~ 5% coil.Mukuona dambudziko rekushandisa simba guru mukushanda kweA AC contactors, kubvira muna 1981, gwaro renyika rekuburitswa Nha. 56 yakaratidza kuti matanho ekuchengetedza simba evanoshandisa AC contactors anofanirwa kushandiswa.Mushure mekutsvakurudza kwenguva refu, mamwe mabasa ekuchengetedza simba akawanikwa, asi chimiro chevanhu vanobatana navo chakashandurwa zvikuru, maitiro akaoma, uye mutengo wekugadzira uri. yakawedzera.Chigadzirwa chakapedzwa chinodhura, kana chiyero chekushandisa idiki, kana chisingaenderane nemaitiro ekushandisa kwevanhu, uye zvimwe zvinokanganisa kuvimbika kwayo kune madhigirii akasiyana, chingava chikonzero chikuru nei contactor simba rokuponesa zvigadzirwa hazvina vakawanda kugamuchirwa pamusika.
1 Dzakawanda dzakajairwa nzira dzekuchengetedza simba dze AC contactors mumusika uye zvakanakira nekuipira kwavo:
Kushanda musimboti ichangobva kugadzirwa simba rokuponesa mudziyo kuti contactor
Chishandiso chekuchengetedza simba chine yemahara yekutsika michina, uchishandisa iyo musimboti we crank link lock (kuvhura chete 0.15N-0.3N simba), iyo michina yakanamira, ita iyo yekubata electromagnet inogona kuchengetedza mapoka ese ekusangana pasina kushandisa simba, kuvhura chinangwa kuchengetedza simba; nekuti iri mechanical lock, hupenyu hwayo hahugone kunge hwakanyanya kukwirira, dzinenge 35,000 nguva, saka inoshandiswa mukuenderera mberi kwekushanda zviitiko, senge control fan, pombi uye capacitor compensation cabinet.Nheyo yekushanda ndeyotevera:
Chishandiso chekuchengetedza simba chakabatana kune chinobata, chinosanganisira imba, tsvimbo yekutamba, yemahara yekutsika, inowanzovharwa micro switch, tsvimbo, simba rekuchengetedza coil uye electromagnetic buckle assembly.Tanga tsvimbo nekubata kweanobata, uchishandisa crank link iyo yekiyi musimboti, iyo meshini yakanyatsonamira, micropower electromagnetic buckle chikamu core suction extrusion micro switch, ita kazhinji yakavharwa micro switch yekubata inowanzovharwa kuti kazhinji yakavhurika kubata, iyo coil yesimba rekubatanidza, iyo electromagnet isina simba rekushandisa inogona kuramba ichichengetedza yese inoshanda yeboka rekusangana, iripo chete kubva kune inochengetedza simba coil kuburikidza.Kana chiratidzo chekudzora chikangoerekana chaiswa kana gidhi remagetsi rinongoerekana ratadza, iyo micropower inoshandisa electromagnetic. tripping component inosundidzira chinongedzo kuti ibvise tambo yemahara, uye chibatiso chekutanga chinodzokera kunzvimbo yekutanga pasi peiyo contactor counterforce chitubu.Nekuti micro-simba rekushandisa electromagnetic unbuckle chikamu chinodiwa kuvhura iyo simba idiki kwazvo inogona kuita iyo electromagnet kuvhura, kuzadzisa chinangwa chekuchengetedza simba.
Figure 1 iphrofayli dhayagiramu ye contactor yakakosha simba rekuchengetedza mudziyo uye contactor kana relay.
FIG. 2 dhiyabhorosi yekubatanidza dhizaini yeyakakosha simba rekuchengetedza mudziyo uye inobatika kana relay.
3. Hunhu hweiyo ichangobva kugadzirwa yakakosha simba rekuchengetedza mudziyo kune contactors
3.1 Hapana bhuku rekugadzirisa zvakare: gidhi remagetsi rinongoerekana radzima, dunhu guru rinozobviswa otomatiki, pasina gadziriso yemanyorero;
3.2 Mechanical interlocking basa inovimbisa kuchengetedzwa uye kuvimbika kwezvigadzirwa
Chishandiso chacho chakashongedzerwawo nemakina anopindirana basa, kana chivharo chikasasimbisa dhizaini, coil iri mucontator haizodzimi, kuitira kuti iyo huru yekubata irambe yakavharika, saka kana mudziyo usingakwanisi kuiswa mukushandiswa. kana kukuvadzwa, hazvizokanganisa kushandiswa kwakajairika kweiyo contactor yepakutanga, asi chigadzirwa hachisisiri kuchengetedza simba.
3.3 Hapana magetsi ekuwedzera anodiwa
Sezvinoratidzwa muMufananidzo 3, chigadziro chekuchengetedza simba hachidi simba rekubatsira, pamwe chete nemagetsi makuru, uye rinogonawo kuwedzera bhatani rekumira kuti ritonge kure kure, pasina njodzi dzekuchengetedza.
3.4 Plug uye Tamba
Simba rekuchengetedza simba rinosungirirwa zvakananga pane zvigadzirwa zve contactor, yekare contactor kana relay inogona kushandiswa pasina kuchinjwa; kuisirwa nyore, kushandiswa kwakakura siyana.
3.5 Kunyanya kushanda nesimba uye kuchengetedza simba kweanopfuura 90%
Paunenge uchishandiswa nemudziyo, iyo AC yekubatanidza musimboti haiburitse nguva nenguva, hapana vibration, saka hapana ruzha, inogona kuderedza zvakanyanya kushandiswa kwesimba, kugadzirisa kuri nyore, kudzikisa zvinobudirira mutengo wekushandisa.
3.6 Usakanganise iyo yekutanga yekubata kana basa, asi zvakare mamwe anoshanda ekubatsira ekubatsira anogona kuwedzerwa
Usatore iyo yekutanga yekubatsira kuonana, asiwo zvinoenderana nezvinodiwa, dhizaini yekuwedzera yekubatsira kuonana, kunonoka basa uye capacitor yakakosha simba rekuchengetedza mudziyo, kuitira kuti ive nemabasa akasiyana.
3.7 Inogona kuwedzera iyo anti-sway magetsi basa
Ichi chishandiso chine imwe kunonoka basa, inobudirira kugadzirisa dambudziko re "kuzunungusa magetsi" .Parizvino, pasi pemamiriro akafanana, hupenyu hwekusangana hwesimba rekuchengetedza AC contactor uye yechinyakare AC contactor inowedzerwa ne3-5 nguva, kuderedza kushanda. uye mari yekugadzirisa.
3.8 Wide voltage inoshanda renji
Wide voltage suction 0.8-1.1US, kuburitsa voltage 20% ~ 75% US, AC-DC contactor universal.
Nguva yekutumira: Kubvumbi-22-2022
