Kusankhidwa kwa Low Voltage AC Contactor mu Electrical Design

Low-voltage AC contactors amagwiritsidwa ntchito kwambiri kuyatsa ndi kuzimitsa magetsi amagetsi, omwe amatha kuwongolera zida zamagetsi kuchokera patali, ndikupewa kuvulaza munthu poyatsa ndi kuzimitsa magetsi a zida. Kusankhidwa kwa AC contactor n'kofunika kwambiri kwa ntchito yachibadwa ya zida mphamvu ndi mizere mphamvu.
1. Kapangidwe ndi magawo a AC contactor
Nthawi zambiri, chipangizo cha AC cholumikizira chimafunikira kuti chikhale ndi mawonekedwe ophatikizika, osavuta kugwiritsa ntchito, chida chabwino chowombera maginito cholumikizirana choyenda komanso chokhazikika, chozimitsa bwino cha arc, ziro flashover, ndi kukwera pang'ono kwa kutentha. Malinga ndi njira yozimitsira arc, imagawidwa kukhala mtundu wa mpweya ndi mtundu wa vacuum, ndipo malinga ndi njira yogwirira ntchito, imagawidwa mumtundu wa electromagnetic, mtundu wa pneumatic ndi electromagnetic pneumatic type.
The oveteredwa voteji magawo a contactor anawagawa voteji mkulu ndi otsika voteji, ndi otsika voteji zambiri 380V, 500V, 660V, 1140V, etc.
Mphamvu yamagetsi imagawidwa m'magulu osinthika komanso olunjika malinga ndi mtundu wake. magawo panopa monga oveteredwa ntchito panopa, anavomereza Kutentha panopa, kupanga panopa ndi kuswa panopa, anagwirizana Kutentha panopa wa kukhudzana wothandiza ndi nthawi yochepa kupirira panopa contactor, etc. General contactor chitsanzo magawo kupereka anagwirizana Kutentha panopa, ndipo pali angapo oveteredwa. mafunde oyendera ogwirizana ndi kutenthetsa komwe kwagwirizana. Mwachitsanzo, kwa CJ20-63, mawonekedwe ogwiritsira ntchito omwe amalumikizana nawo amagawidwa kukhala 63A ndi 40A. 63 mu chitsanzo chizindikiro amatanthauza anagwirizana Kutentha panopa, amene akugwirizana ndi kamangidwe kutchinjiriza wa contactor a chipolopolo, ndi oveteredwa ntchito panopa zikugwirizana ndi anasankha katundu panopa, zokhudzana ndi mlingo voteji.
AC contactor coils anawagawa 36, ​​127, 220, 380V ndi zina zotero malinga ndi voteji. Chiwerengero cha mizati ya contactor lagawidwa 2, 3, 4, 5 mitengo ndi zina zotero. Pali awiriawiri angapo othandizira omwe amalumikizana ndi omwe amatseguka komanso otsekedwa, ndipo amasankhidwa malinga ndi zosowa zawo.
Magawo ena akuphatikizapo kugwirizana, kuswa nthawi, moyo wamakina, moyo wamagetsi, maulendo ovomerezeka ovomerezeka, mawaya ovomerezeka kwambiri, miyeso yakunja ndi miyeso ya unsembe, etc.
Mitundu Yambiri Yolumikizirana
Gwiritsani ntchito ma code a gulu kuti mukhale chitsanzo cha katundu wamba
AC-1 non-inductive kapena yaying'ono-inductive katundu, resistive katundu kukana ng'anjo, chotenthetsera, etc.
Kuyamba ndi kusweka kwa AC-2 mabala olowetsa ma cranes, ma compressor, hoist, ndi zina zambiri.
AC-3 khola induction motor kuyambira, kuswa mafani, mapampu, etc.
AC-4 cage induction motor yoyambira, kubweza braking kapena kutseka kwamoto fan, mpope, chida cha makina, ndi zina zambiri.
AC-5a kutulutsa nyali pa-ozimitsa mpweya wothamanga kwambiri nyali monga mercury nyali, halogen nyali, etc.
Nyali zozimitsa za nyali za AC-5b za incandescent
AC-6a thiransifoma on-off kuwotcherera makina
Ozimitsa capacitor wa AC-6b capacitor
Zida zapakhomo za AC-7a ndi mavuvuni a microwave, zowumitsira manja, ndi zina zotero.
Firiji yanyumba ya AC-7b, makina ochapira ndi mphamvu zina zoyatsa ndi kuzimitsa
AC-8a mota kompresa yokhala ndi hermetic firiji kompresa yokhala ndi kutulutsidwa kwapamanja kwapang'onopang'ono
AC-8b mota kompresa yokhala ndi hermetic firiji kompresa yokhala ndi kutulutsidwa kwapamanja kowonjezera
