A contactor ndi chipangizo chamagetsi chimene chimagwiritsidwa ntchito posintha mabwalo ndi kuzimitsa. Mwakutero, zolumikizira zamagetsi zimapanga gulu laling'ono la ma switch ma electromagnetic omwe amadziwika kuti ma relay.
Relay ndi chipangizo chosinthira magetsi chomwe chimagwiritsa ntchito koyilo yamagetsi kuti atsegule ndi kutseka gulu la zolumikizirana Izi zimapangitsa kuti dera liyambe kuyatsa kapena kuyimitsa kapena kusokoneza dera). A contactor ndi mtundu wapadera wa kupatsirana, ngakhale pali kusiyana zofunika pakati pa wolandirana ndi contactor.
Othandizira amapangidwa kuti azigwiritsidwa ntchito m'mapulogalamu omwe kuchuluka kwamakono kumafunika kusinthidwa. Ngati mukuyang'ana tanthauzo lachidule la contactor lamagetsi, munganene zinthu monga izi:
Cholumikizira ndi chipangizo chosinthira magetsi choyendetsedwa ndi magetsi, chopangidwa kuti chitsegulidwe mobwerezabwereza ndi kutseka dera, Contactors amakonda kugwiritsidwa ntchito pamapulogalamu apamwamba kwambiri kuposa ma relay wamba, omwe amagwira ntchito yofananira ndikusintha kwakanthawi kochepa.
Tsitsani Catalog PDFAn magetsi contactor ntchito zosiyanasiyana zinthu pamene pakufunika kusinthana mphamvu dera mobwerezabwereza. Monga ma switch a relay, adapangidwa ndikupangidwira kuti agwire ntchitoyi mozungulira masauzande ambiri.
Othandizira amasankhidwa makamaka kuti agwiritse ntchito mphamvu zambiri kuposa ma relay. Izi ndichifukwa choti amatha kuloleza ma voltages otsika komanso mafunde kuti asinthe. kapena kuzungulira kwamagetsi, ma voliyumu apamwamba kwambiri/ozungulira pano akuyatsa ndi kuzimitsa.
Childs, ndi contactor adzakhala ntchito zinthu pamene katundu mphamvu ayenera kuyatsa ndi kuzimitsa pafupipafupi kapena mofulumira. Komabe, amathanso kukhazikitsidwa kuti aziyendetsa dera akatsegulidwa (nthawi zambiri amatsegula, kapena NO contacts), kapena kutseka mphamvu kudera ikayatsidwa (nthawi zambiri imatsekedwa, kapena ma NC contacts).
Mapulogalamu awiri apamwamba a cholumikizira ali ngati choyambira chamagetsi - monga omwe amagwiritsa ntchito zolumikizira zothandizira ndi zolumikizira kuti azigwiritsa ntchito pamagalimoto amagetsi - komanso pamakina owongolera zowunikira zamphamvu kwambiri.
Pamene contactor ntchito ngati maginito sitata kwa galimoto yamagetsi, izo kawirikawiri amaperekanso osiyanasiyana mbali zina chitetezo monga mphamvu-cutoff, chitetezo dera lalifupi, chitetezo mochulukira, ndi chitetezo pansi-voltage.
Ma contactor omwe amagwiritsidwa ntchito kuwongolera kuyimitsidwa kowunikira kwamphamvu kwambiri nthawi zambiri amakonzedwa mokhazikika, kuti achepetse kugwiritsa ntchito mphamvu zonse. Dongosololi limaphatikizapo ma coil awiri a electromagnetic omwe amagwira ntchito limodzi. Koyilo imodzi imatseka zolumikizana ndi dera zikapatsidwa mphamvu pang'ono ndikuzitseka mwamphamvu. Koyilo yachiwiri idzatsegulanso ikayatsidwa. Kukhazikitsa kotereku kumakhala kofala makamaka pakukhazikitsa ma ofesi akuluakulu, ogulitsa ndi mafakitale. Mfundoyi ili ngati momwe chingwe cholumikizira chimagwirira ntchito, ngakhale chotsiriziracho chimagwiritsidwa ntchito pafupipafupi m'mabwalo ang'onoang'ono okhala ndi katundu wocheperako.
Monga ma contactor amapangidwira makamaka mitundu iyi yamagetsi apamwamba kwambiri, amakhala okulirapo komanso olimba kuposa zida zosinthira. Komabe, ma contactors ambiri amagetsi amapangidwabe kuti azikhala osavuta kunyamula komanso okwera ndipo nthawi zambiri amatengedwa kuti ndi oyenera kugwiritsidwa ntchito m'munda.
Tumizani Mafunso LeroPali zifukwa zingapo zomwe contactor magetsi akhoza kuvutika ndi kulephera ndi zofunika kukonza kapena m'malo. Chofala kwambiri ndi kuwotcherera kapena kulumikizana kumamatira, pomwe zolumikizira za chipangizocho zimakakamira kapena kusakanikirana pamalo amodzi.
Izi zimachitika chifukwa cha mafunde othamanga kwambiri, ma voltages osakhazikika, nthawi zotsika kwambiri zosinthira pakati pa nsonga zaposachedwa chifukwa cha kuwonongeka kwanthawi zonse. Zotsirizirazi nthawi zambiri zimawoneka ngati kuyaka kwapang'onopang'ono kwa ma alloys omwe amakutira zolumikizira, zomwe zimapangitsa kuti mkuwa womwe uli pansiwo ugwirizane.
Chifukwa chinanso chomwe chimalepheretsa contactor ndikuwotcha kwa koyilo, komwe nthawi zambiri kumayamba chifukwa cha kuchuluka kapena kusakwanira) voteji kumapeto kwa ma electromagnetic col. Dothi, fumbi, kapena chinyontho cholowera mumpata wa mpweya wozungulira koyilo zitha kukhalanso chinthu chothandizira.
Kusiyana kwakukulu pakati pa AC contactor ndi DC contactor lagona mapangidwe awo ndi zomangamanga. Zolumikizira za AC zimakongoletsedwa ndi voteji ya AC ndi mawonekedwe apano, pomwe zolumikizira za DC zidapangidwa makamaka kuti zigwirizane ndi voteji ya DC komanso yapano. Zolumikizira za AC nthawi zambiri zimakhala zazikulu ndipo zimakhala ndi magawo osiyanasiyana amkati kuti athe kuthana ndi zovuta zakusintha kwapano.
Posankha AC contactor, muyenera kuganizira zinthu monga voteji ndi mlingo panopa dongosolo AC wanu, zofunika mphamvu ya katundu, mkombero ntchito, ndi aliyense wapadera ntchito-enieni zofunika. Ndibwino kuti mufunsane ndi zomwe wopanga amapanga ndikukambirana ndi katswiri wamagetsi kapena injiniya wodziwa bwino kusankha bwino.
Momwe Othandizira Amagwirira Ntchito?
Kuti mumvetse bwino mmene contactor ntchito, ndi zothandiza kudziwa za zigawo zitatu pachimake cha contactor aliyense magetsischipangizo pamene asonkhanitsidwa. Izi nthawi zambiri zimakhala zozungulira, zolumikizirana, ndi mpanda wa chipangizocho.
The koyilo, kapena electromagnet, ndi chigawo chachikulu cha contactor. Kutengera ndi momwe chipangizocho chikukhazikitsira, chidzachitapo kanthu pakusinthana (kutsegula kapena kutseka) chikalandira mphamvu.
Zolumikizana ndi zigawo za chipangizo chomwe chimanyamula mphamvu kuzungulira dera lomwe likusinthidwa. Pali mitundu yosiyanasiyana ya kukhudzana opezeka contactors kwambiri, kuphatikizapo akasupe ndi kulankhula mphamvu. Mtundu uliwonse umagwira ntchito yapadera pakusamutsa zamakono ndi magetsi
The contactor mpanda ndi mbali ina yofunika ya chipangizo. Izi ndi nyumba wazungulira koyilo ndi kulankhula, kuthandiza insulate zigawo zikuluzikulu contactor a. Chotsekeracho chimateteza ogwiritsa ntchito kuti asagwire mwangozi mbali zilizonse zosinthira, komanso kupereka chitetezo champhamvu ku zoopsa monga kutenthedwa, kuphulika, ndi zoopsa zachilengedwe monga dothi ndi kulowetsa chinyezi.
Mfundo ntchito ya contactor magetsi ndi molunjika. Pamene koyilo yamagetsi imakhala ndi mphamvu yodutsamo mphamvu ya maginito imapangidwa. Izi zimapangitsa armature mkati contactor kusuntha m'njira inayake zokhudza kukhudzana magetsi
Kutengera ndi momwe chipangizocho chinapangidwira komanso momwe chimapangidwira kuti chikhale chotsegula kapena kutseka zolumikizira.
Ngati contactor lakonzedwa monga mwachizolowezi lotseguka (NO), zosangalatsa koyilo ndi voteji kukankhira kulankhula pamodzi, kukhazikitsa dera, ndi kulola mphamvu kuyenda mozungulira dera, Pamene koyilo ndi de-energized, kulankhula adzakhala lotseguka, ndi dera adzakhala kuzimitsa. Umu ndi momwe ma contactors ambiri amapangidwira
A kawirikawiri anatseka (NC) contactor ntchito mosiyana. Dera latha (malumikizidwe atsekedwa) pomwe cholumikizira chimachotsedwa koma chimasokonekera (malumikizidwe otseguka) nthawi iliyonse ikaperekedwa kwa maginito amagetsi, uku ndi kasinthidwe kocheperako kwa olumikizirana, ngakhale ndi njira yodziwika bwino yosinthira masiwichi olandila.
Othandizira amatha kugwira ntchitoyi mwachangu, pamizere yozungulira masauzande (kapena mamiliyoni) pa moyo wawo wonse wogwira ntchito.
