Kodi kusankha contactor, zinthu ziyenera kuganiziridwa posankha contactor, ndi masitepe posankha contactor

1. Posankha contactor, malo ogwira ntchito ayenera kuganiziridwa, ndipo zotsatirazi ziyenera kuganiziridwa.
①Cholumikizira cha AC chiyenera kugwiritsidwa ntchito kuwongolera katundu wa AC, ndipo cholumikizira cha DC chiyenera kugwiritsidwa ntchito ponyamula katundu wa DC.
② Mphamvu yomwe ikugwira ntchito yolumikizirana yayikulu iyenera kukhala yayikulu kuposa kapena yofanana ndi yomwe ikuyendetsedwerako.Komanso tisaiwale kuti oveteredwa ntchito panopa wa kukhudzana waukulu wa contactor ndi yachibadwa pansi pa zinthu zotchulidwa (oveteredwa ntchito voteji, gulu ntchito, pafupipafupi ntchito, etc.) The ntchito mtengo panopa, pamene zinthu zenizeni ntchito ndi osiyana, mtengo wamakono udzasinthanso moyenera.
③ Ma voliyumu ogwira ntchito omwe amalumikizana nawo ayenera kukhala akulu kuposa kapena ofanana ndi voteji ya dera la katundu.
④Voteji yovotera ya koyilo iyenera kukhala yogwirizana ndi mphamvu ya loop

2. Enieni masitepe contactor kusankha
①Sankhani mtundu wa contactor, muyenera kusankha mtundu wa contactor malinga ndi mtundu wa katundu
②Sankhani magawo ovoteledwa a cholumikizira

Malinga ndi chinthu kulamulidwa ndi magawo ntchito, monga voteji, panopa, mphamvu, pafupipafupi, etc., kudziwa magawo oveteredwa wa contactor.

(1) Mphamvu ya koyilo ya cholumikizira iyenera kukhala yotsika, kotero kuti zofunikira za kutchinjiriza kwa cholumikizira zitha kuchepetsedwa ndipo ndizotetezeka kugwiritsa ntchito.Pamene kayendetsedwe ka kayendetsedwe kake kamakhala kosavuta ndipo zipangizo zamagetsi zimakhala zochepa, magetsi a 380V kapena 220V akhoza kusankhidwa mwachindunji.Ngati dera ndizovuta.Kuchuluka kwa zida zamagetsi kupitilira 5, ma koyilo okhala ndi 36V kapena 110V voteji amatha kusankhidwa kuti atsimikizire chitetezo.Komabe, pofuna kuwongolera ndi kuchepetsa zida, nthawi zambiri zimasankhidwa molingana ndi magetsi enieni a gridi.
(2) Mafupipafupi ogwiritsira ntchito galimotoyo si apamwamba, monga ma compressor, mapampu amadzi, mafani, ma air conditioners, etc., oveteredwa panopa wa contactor ndi wamkulu kuposa panopa oveteredwa katundu.
(3) Kwa ma motors olemetsa, monga injini yayikulu ya zida zamakina, zida zonyamulira, ndi zina zambiri, mawonekedwe apano a contactor ndiakulu kuposa momwe amavotera.
(4) Zopangira ma motors apadera.Pamene nthawi zambiri amathamanga mu chikhalidwe kuyambira ndi m'mbuyo, ndi contactor akhoza pafupifupi anasankha malinga ndi moyo magetsi ndi kuyambira panopa.CJ10Z, CJ12,
(5) Mukamagwiritsa ntchito cholumikizira kuti muwongolere thiransifoma, kukula kwa inrush pano kuyenera kuganiziridwa.Mwachitsanzo, makina owotcherera magetsi, contactors akhoza zambiri kusankhidwa malinga ndi kawiri oveteredwa panopa thiransifoma, monga CJT1, CJ20, etc.
(6) Mawonekedwe apano a contactor amatanthawuza kuchuluka kovomerezeka kwa wolumikizana ndi nthawi yayitali, nthawiyo ndi ≤8H, ndipo imayikidwa pagulu lowongolera lotseguka.Ngati kuzirala kulibe, pamene contactor amasankhidwa, oveteredwa panopa wa contactor adzakhala The panopa amasankhidwa malinga 1.1-1.2 nthawi oveteredwa panopa katundu.
(7) Sankhani nambala ndi mtundu wa contactors.Nambala ndi mtundu wa ojambula ayenera kukwaniritsa zofunikira za dera lolamulira.
