Structural mfundo ya contactor

Contactor ali pansi athandizira chizindikiro kunja akhoza basi kuyatsa kapena kuzimitsa dera waukulu ndi katundu kulamulira zipangizo, kuwonjezera pa galimoto kulamulira, Angagwiritsidwenso ntchito kulamulira kuyatsa, Kutentha, zitsulo zowotcherera, capacitor katundu, oyenera ntchito pafupipafupi, ulamuliro kutali amphamvu. dera lamakono, ndipo ali ndi ntchito yodalirika, moyo wautali, kukula kochepa, kutsika kwapansi kwa ntchito yoteteza chitetezo, ndi chimodzi mwa zigawo zofunika kwambiri komanso zomwe zimagwiritsidwa ntchito kwambiri mu dongosolo lolamulira la relay-contactor.

Zosinthika contactor ndi mtundu wa ntchito kulamulira apamwamba mphamvu galimoto zabwino ndi n'zosiyana mawotchi chosinthika ac contactor, tichipeza contactors awiri muyezo ndi makina interlock wagawo, anaikira ubwino ac contactor ndi n'zosiyana lophimba, ntchito yosavuta, otetezeka ndi odalirika, mtengo wotsika. , yomwe imagwiritsidwa ntchito makamaka pamayendedwe abwino komanso obwerera kumbuyo, kubweza mabuleki, kugwira ntchito kosalekeza komanso kugwira ntchito kwama point.

Contactors akhoza kuyatsa ndi kusagwirizana katundu panopa, koma sangathe kudula yochepa dera panopa, choncho nthawi zambiri ntchito ndi fuses ndi matenthedwe relays.

gawa

Pali mitundu yambiri yolumikizirana, ndipo pali njira zinayi zogawa, kuphatikiza yoyamba.

① imagawidwa mu AC contactor ndi DC contactor malinga ndi mtundu waposachedwa wa dera wolumikizidwa ndi wolumikizana wamkulu.

② imagawidwa kukhala monopole, bipolar, 3,4, ndi mitengo 5 malinga ndi kuchuluka kwa mitengo ya omwe amalumikizana nawo.

③ imagawidwa m'mitundu yotseguka ndipo nthawi zambiri imatsekedwa molingana ndi koyilo yayikulu yolumikizirana.

④ imagawidwa kukhala palibe chipangizo chozimitsira arc ndipo palibe chipangizo chozimitsira arc molingana ndi njira yozimitsa ya arc.

Mfundo ya kamangidwe

Zigawo zazikulu za contactor ndi;electromagnetic system, kukhudzana, arc kuzimitsa makina, othandizira othandizira, bulaketi ndi nyumba, etc. batani likakanikizidwa, koyiloyo imakhala ndi mphamvu, tsinde lokhazikika limapangidwa ndi maginito, ndipo maziko osuntha amayamwa kuti ayendetse shaft kuti agwirizane. dongosolo kugawanika ndi kutseka ntchito, kotero kuti kulumikiza kapena kulumikiza kuzungulira.Pamene batani amamasulidwa, ndondomeko ndi zosiyana ndi pamwamba.

Main luso magawo

① oveteredwa voteji ntchito: zambiri amatanthauza voteji oveteredwa wa kukhudzana chachikulu, kuphatikizapo AC: 380V, 660V, 1140V, DC: 220V, 440V, 660V, etc.

② Ovotera ntchito panopa: zambiri amatanthauza panopa oveteredwa wa kukhudzana chachikulu, kuphatikizapo 6A, 9A, 12A, 16A, 25A, 40A, 100A, 160A, 250A, 400A, 600A, 1000A, etc.

③ kuyatsa ndi kutha mphamvu: kumatanthauza mtengo wapano womwe wolumikizira amatha kuyatsa ndikuphwanya chipangizo cholandirira magetsi.

④ anavomereza Kutentha panopa: mu mayesero pansi mikhalidwe yotchulidwa, panopa ntchito pa 8h, ndi pazipita panopa amatengedwa pamene kutentha kwa gawo lililonse si upambana malire mtengo.

⑤ pafupipafupi ntchito: amatanthauza kuchuluka kwa ntchito zomwe zimaloledwa pa ola limodzi.

⑥ Moyo wamakina ndi moyo wamagetsi: imatanthawuza kuchuluka kwa ntchito zomwe zisanachitike kulephera kwa makina a mzati waukulu popanda load.Mechanical moyo umagwirizana ndi ma frequency opareshoni.Moyo wamagetsi ndi kuchuluka kwa ntchito zonyamula pamtengo waukulu popanda kukonza. Moyo wamagetsi umayenderana ndi mtundu wa kagwiritsidwe ntchito, kuvotera komwe kumagwira ntchito, komanso mphamvu yogwiritsira ntchito.
