Kusankha mfundo ya AC contactor

The contactor ntchito ngati chipangizo kwa kusinthana pa katundu magetsi. Kusankhidwa kwa contactor kuyenera kukwaniritsa zofunikira za zida zoyendetsedwa. Pokhapokha kuti oveteredwa voteji ntchito ndi chimodzimodzi ndi oveteredwa ntchito voteji wa zida ankalamulira, mphamvu katundu, gulu ntchito, kulamulira Mode, pafupipafupi ntchito, moyo ntchito, njira unsembe, unsembe kukula ndi chuma ndi maziko kusankha. Mfundo zosankhidwa ndi izi:
(1) Mulingo wamagetsi a AC contactor uyenera kukhala wofanana ndi wa katundu, ndipo mtundu wa contactor uyenera kukhala woyenera katunduyo.
(2) Kuwerengetsera panopa katundu ayenera kugwirizana ndi mphamvu mlingo wa contactor, ndiko kuti, mawerengedwe panopa ndi zosakwana kapena wofanana ndi oveteredwa ntchito panopa contactor. The kusintha panopa contactor ndi wamkulu kuposa poyambira panopa katundu, ndi kusweka panopa kuposa kuswa panopa pamene katundu ikuyenda. Mawerengedwe amakono a katundu ayenera kuganizira malo enieni ogwira ntchito ndi momwe amagwirira ntchito. Kwa katundu wokhala ndi nthawi yayitali yoyambira, chiwongolero cha theka la ola sichingathe kupitilira kutentha komwe kwagwirizana.
(3) Sanjani molingana ndi kukhazikika kwakanthawi kochepa komanso kutentha kwamafuta. Gawo laling'ono lachidule la magawo atatu la mzere sayenera kupitirira mphamvu yotentha komanso yotentha yomwe imaloledwa ndi contactor. Pamene ntchito contactor kuswa yochepa dera panopa, mphamvu kuswa contactor ayeneranso kufufuzidwa.
(4) The voliyumu voteji ndi panopa wa contactor kukopa koyilo ndi chiwerengero ndi mphamvu panopa wa kukhudzana wothandiza adzakwaniritsa mawaya zofunika dera ulamuliro. Kuganizira kutalika kwa mzere wolumikizidwa ndi dera control contactor, ambiri analimbikitsa ntchito voteji mtengo, contactor ayenera kugwira ntchito pa 85 kuti 110% ya voteji oveteredwa. Ngati mzerewo ndi wautali kwambiri, koyilo ya contactor sangayankhe lamulo lotseka chifukwa cha dontho lalikulu lamagetsi; chifukwa cha kuchuluka kwa mzerewu, sizingagwire ntchito pa lamulo loyenda.
(5) Chongani kololeka ntchito pafupipafupi wa contactor malinga ndi kuchuluka kwa ntchito. Ngati ma frequency ogwiritsira ntchito akupitilira mtengo womwe watchulidwa, zomwe zidavoteredwa ziyenera kuwirikiza kawiri.
(6) Magawo a magawo achitetezo afupikitsa ayenera kusankhidwa molumikizana ndi magawo a contactor. Posankha, chonde onani bukhu la catalog, lomwe nthawi zambiri limapereka tebulo lofananira la olumikizirana ndi ma fuse.
Mgwirizano wapakati pa cholumikizira ndi chowotcha mpweya uyenera kutsimikiziridwa molingana ndi kuchuluka kwazomwe zimachulukira komanso chitetezo chanthawi yayitali cha wowononga mpweya. Kutentha komwe kwagwirizana kwa cholumikizira kuyenera kukhala kocheperako kuposa kuchulukira kwamagetsi kwa cholumikizira mpweya, ndipo kuyatsa ndi kuyimitsa kwa cholumikizira kuyenera kukhala kotsika pang'ono kuposa kutetezedwa kwanthawi yayitali kwa wowononga dera, kuti wophwanya dera athe kuteteza. cholumikizira. Pochita, contactor amavomereza kuti chiŵerengero cha Kutentha panopa kwa oveteredwa ntchito panopa ndi pakati pa 1 ndi 1.38 pa mlingo voteji, pamene wosweka dera ali ambiri inverse nthawi zimamuchulukira magawo coefficient, amene ali osiyana mitundu yosiyanasiyana ya ophwanya dera, kotero izo ndizovuta kugwirizana pakati pa awiriwa Pali muyezo, womwe sungathe kupanga tebulo lofananira, ndipo umafuna kuwerengera kwenikweni.
(7) Mtunda wa unsembe wa contactors ndi zigawo zina ziyenera kutsata miyezo yoyenera ya dziko ndi ndondomeko, ndi kukonza ndi maulendo a waya ayenera kuganiziridwa.
3. Kusankhidwa kwa AC contactors pansi katundu osiyana
Pofuna kupewa kukhudzana kudzimatira ndi ablation wa contactor ndi kutalikitsa moyo utumiki wa contactor, contactor ayenera kupewa pazipita panopa katundu kuyambira, komanso kuganizira zinthu zoipa monga kutalika kwa nthawi yoyambira, choncho m'pofunika kulamulira katundu wa contactor pa ndi kuzimitsa. Malinga ndi mawonekedwe amagetsi a katunduyo komanso momwe zinthu zilili pamagetsi, mphamvu yoyambira ya katundu wosiyanasiyana imawerengedwa ndikusinthidwa.
