A contactor chinhu chemagetsi chinoshandiswa zvakanyanya pakushandura masekete nekudzima. Saka nekudaro, macontactor emagetsi anoumba chikamu chidiki chemagetsi emagetsi anozivikanwa serelays.
A relay chinhu chinoshandiswa nemagetsi chinoshandisa electromagnetic coil kuvhura nekuvhara seti yevanobatika Ichi chiito chinoguma nekuita kuti dunhu rive simba kana kudzima kumisikidza kana kukanganisa dunhu). A contactor ari chaiwo mhando relay, kunyange pane zvimwe zvakakosha misiyano pakati relay uye contactor.
Macontactor anonyanya kugadzirwa kuti ashandiswe mumashandisirwo apo huwandu hukuru hwezvino hunoda kuchinjwa. Kana iwe uchitsvaga pfupiso yemagetsi contactor tsanangudzo, unogona kutaura chimwe chinhu sechinotevera:
A contactor chinhu chemagetsi chinodzorwa switching mudziyo, yakagadzirirwa kudzokororwa kuvhura uye kuvhara dunhu, Contactors vanowanzo shandiswa kune yakakwirira ikozvino-inotakura zvikumbiro pane yakajairika relays, iyo inoita basa rakafanana ine yakaderera ikozvino switching.
Dhaunirodha Catalog PDFMutambo wemagetsi unoshandiswa munzvimbo dzakasiyana-siyana apo pane chido chekushandura simba kudunhu kakawanda. Kufanana nerelay switch, dzakagadzirwa uye dzakavakwa kuti dziite basa iri pamusoro pezviuru zvakawanda zvekutenderera.
Contactors anonyanya kusarudzirwa epamusoro masimba ekushandisa pane relay. Izvi zvinodaro nekuda kwekugona kwavo kubvumira yakaderera voltages uye mafungu kuchinja. kana kutenderera kwemagetsi, yakakwira kureba voltage/current circuit on and off.
Kazhinji, munhu contactor achashandiswa mumamiriro ezvinhu apo simba mitoro inoda kuvhurwa uye kudzima kakawanda kana nokukurumidza. Nekudaro, iwo anogona zvakare kugadziridzwa kungave kusimba padunhu kana akabatidzwa (kazhinji akavhurika, kana NO mabatiro), kana kuvhara simba kudunhu kana rakaitwa (kazhinji rakavharwa, kana NC mazita).
Iwo maviri echinyakare maapplication eanobatika akaita seyemagetsi mota inotangisa - senge ayo anoshandisa ebetsero macontacts uye majoinhi ekushandisa mumotokari dzemagetsi - uye mumagadzirirwo emagetsi ane simba guru.
Kana iyo contactor inoshandiswa semagnetic starter yemotokari yemagetsi, inowanzopawo huwandu hwezvimwe zvekuchengetedza zvakadai semagetsi-cutoff, short circuit protection, overload protection, uye under-voltage protection.
Macontactor ari kushandiswa kudzora epamusoro-simba magetsi ekuisa anowanzo kurongeka mukugadzirisa latching, kudzikisa simba rose rekushandisa. Kurongeka uku kunosanganisira maviri emagetsi coil anoshanda ari tandem. Imwe coil inovhara madhigirii edunhu kana apihwa simba muchidimbu uye ovabata akavharwa nemagineti. Koiri yechipiri inoavhura zvakare kana yaiswa magetsi. Iyi mhando yekuseta inonyanya kuwanda kune otomatiki ehombe-hombe hofisi, yekutengesa uye maindasitiri emwenje setups. Nheyo yacho yakafanana nemashandiro anoita relay relay, kunyangwe iyo yekupedzisira ichiwanzo shandiswa mumaseketi madiki ane mitoro yakaderedzwa.
Sezvo macontactor akaitirwa zvakananga kune aya marudzi eakakwira voltage maapplication, anowanzo kuve akakura mumuviri uye akasimba kupfuura akajairwa relay switching zvishandiso. Nekudaro, mazhinji emagetsi emagetsi achiri kugadzirwa kuti agone kutakurika uye anotakurika uye anowanzoonekwa akakodzera kwazvo kushandiswa mumunda.
Tumira Kubvunza NhasiPane zvikonzero zvakati kuti nei mudhuri wemagetsi angatadza kutadza uye anoda kugadziriswa kana kutsiviwa. Iyo inonyanya kuzivikanwa ndeyekubata welding kana kubata kunamatira, uko mabatiro emudziyo anonamira kana kusanganiswa mune imwe nzvimbo.
Izvi zvinowanzoitika mhedzisiro yeakawandisa inrush currents, kusagadzikana kudzora voltages, yakanyanya kuderera nguva yekuchinja pakati pepamusoro peak ikozvino nekuda kwekupfeka kwakajairwa uye kubvaruka. Iyo yekupedzisira inowanzo ratidza sekutsva zvishoma nezvishoma kubva kune alloys anovhara macontaterminals, zvichiita kuti mhangura iri pachena iri pasi ibatane.
Chimwe chikonzero chakajairika chekutadza kubata bata kupiswa kwecoil, kazhinji kunokonzerwa nekuwanda kana kusakwana) voltage kune chero kumagumo kweelectromagnetic col. Tsvina, guruva, kana hunyoro hunopinda mugomba remhepo rakatenderedza coil rinogonawo kukonzera.
Musiyano mukuru pakati pe AC contactor uye DC contactor nhema mukugadzira kwavo uye kuvaka. AC contactors akagadziridzwa AC voltage uye zvazvino maitiro, nepo DC contactors akagadzirirwa zvakanangana DC voltage uye ikozvino. AC macontactor anowanzo kukura muhukuru uye ane akasiyana emukati maficha ekugadzirisa matambudziko ekuchinjanisa ikozvino.
Paunenge uchisarudza AC contactor, unofanirwa kufunga nezvezvinhu zvakaita sevoltage uye chiyero chazvino cheiyo AC system yako, simba rinodiwa pamutoro, kutenderera kwebasa, uye chero chakakosha-chaiwo zvinodiwa. Zvinokurudzirwa kubvunza zvakatemwa nemugadziri uye kubvunza ane hunyanzvi hwemagetsi kana mainjiniya kuti asarudze zvakakodzera.
MaContactor Anoshanda Sei?
Kuti unzwisise zviri nani kuti contactor inoshanda sei, zvinobatsira kuziva pamusoro pezvikamu zvitatu zvakakosha chero ipi zvayo yemagetsismudziyo kana waunganidzwa. Aya anowanzo ari coil, vanobatika, uye mudziyo wakavharirwa.
Iyo coil, kana electromagnet, ndicho chinhu chakakosha checontator. Zvichienderana nemagadzirirwo akaitwa mudziyo, ichaita chaiyo chiitiko pane switch maconta (kuvhura kana kuvhara) kana yagamuchira simba.
Macontacts ndiwo zvikamu zvemudziyo unotakura simba padunhu riri kuchinjwa. Kune marudzi akasiyana-siyana ekubatika anowanikwa mune akawanda contactors, kusanganisira zvitubu uye simba contacts. Rudzi rwega rwega runoita basa chairo mukufambisa ikozvino uye voltage
The contactor yakavharirwa chimwe chikamu chinokosha mudziyo. Iyi ndiyo imba inotenderedza coil uye vanobatika, vachibatsira kuti insulate contactor wacho zvinokosha zvinoriumba. Iyo yakavharirwa inodzivirira vashandisi kubva pakubata netsaona chero zvikamu zvinofambisa zvekuchinja, pamwe nekupa dziviriro yakasimba panjodzi dzakadai sekupisa, kuputika, uye njodzi dzezvakatipoteredza senge tsvina uye hunyoro ingress.
Nheyo yekushandisa yemagetsi contactor yakananga. Kana iyo electromagnetic coil ine ikozvino yakapfuura nepakati payo magineti inogadzirwa. Izvi zvinoita kuti armature mukati contactor kufamba neimwe nzira maererano magetsi kuonana
Zvichienderana nemagadzirirwo akaitwa mudziyo wacho uye basa raunenge waitirwa izvi rinowanzova rekuvhura kana kuvhara vanobatika.
Kana iyo contactor yakagadzirirwa sezvinowanzoita yakazaruka (NO), inofadza iyo coil ine voltage ichasundira mazita pamwe chete, kumisa dunhu, uye kubvumira simba kuti riyerere kumativi edunhu, Kana iyo coil iri de-energized, mazita achave akazaruka, uye dunhu richave ravharwa. Aya ndiwo magadzirirwo evazhinji contactors
A inowanzovharwa (NC) contactor inoshanda zvakapesana. Dunhu racho rakazara (mabati akavharwa) nepo anobatika achibviswa-enerqised asi anovhiringwa (mabati akavhurika) pese pazvinopihwa kune electromagnet, Uku ndiko kurongeka kushoma kwevanobatika, kunyangwe iri yakajairwa kumwe kuseta kweyakajairwa relay switch.
Vanobatika vanogona kukurumidza kuita basa iri rekuchinja, pamusoro pezviuru zvakawanda (kana mamirioni) ematenderedzwa mukati mehupenyu hwavo huzere hwekushanda.
