I-contactor iyisisetshenziswa sikagesi esisetshenziswa kabanzi ukushintsha nokuvala amasekhethi. Kanjalo, abathintwayo bakagesi bakha isigaba esingaphansi sokushintshwa kwe-electromagnetic eyaziwa ngokuthi ama-relay.
I-relay iyithuluzi elishintshayo elisebenza ngogesi elisebenzisa ikhoyili kazibuthe ukuvula nokuvala isethi yoxhumana nabo Lesi senzo siholela ekuvuleni noma ukuvala isekethe ukusungula noma ukuphazamisa isekhethi). I-contactor uhlobo oluthile lwe-relay, nakuba kukhona umehluko obalulekile phakathi kwe-relay kanye ne-contactor.
Othintana nabo ngokuyinhloko bakhelwe ukusetshenziswa ezinhlelweni lapho inani elikhulu lamanje lidinga ukushintshwa. Uma ufuna incazelo emfushane ye-contactor kagesi, ungasho into efana nalena elandelayo:
I-contactor iyidivayisi yokushintsha elawulwa ngogesi, eklanyelwe ukuvula nokuvala isekethe ngokuphindaphindiwe, Abathintwayo bavame ukusetshenziselwa izinhlelo zokusebenza eziphethe amandla aphezulu kunokudlulisa okujwayelekile, okwenza umsebenzi ofanayo ngokushintsha okuphansi kwamanje.
Landa i-PDF yekhathalogiI-contactor kagesi isetshenziswa ezimweni eziningi lapho kunesidingo sokushintsha amandla kumjikelezo ngokuphindaphindiwe. Njengamaswishi e-relay, aklanywe futhi akhelwe ukwenza lo msebenzi ezinkulungwaneni eziningi zemijikelezo.
Oxhumana nabo bakhethelwa izinhlelo zokusebenza zamandla aphezulu kunokudlulisa. Lokhu kungenxa yekhono labo lokuvumela ama-voltage aphansi nama-currents ukuthi ashintshe. noma umjikelezo wamandla, i-voltage ephezulu kakhulu/isekethe yamanje ivuliwe noma ivaliwe.
Ngokuvamile, i-contactor izosetshenziswa ezimweni lapho imithwalo yamandla idinga ukuvulwa futhi icishwe njalo noma ngokushesha. Kodwa-ke, zingase futhi zilungiselelwe ukuthi zibe namandla kusekethe uma zenziwe zisebenze (ngokuvamile zivuliwe, noma AKUKHO abathintwayo), noma ukuvala amandla kusekethe uma kucushwe (ngokuvamile kuvalwe, noma abathintwayo be-NC).
Izinhlelo zokusebenza ezimbili zakudala ze-contactor zinjengesiqalisi semoto kagesi - njengalezo ezisebenzisa izixhumi ezisizayo nezixhumi ukuze zisetshenziswe ezimotweni zikagesi - kanye nasezinhlelweni zokulawula izibani ezinamandla amakhulu.
Uma i-contactor isetshenziswa njengesiqalisi kazibuthe senjini kagesi, ngokuvamile izohlinzeka ngohlu lwezinye izici zokuphepha ezifana nokunqanyulwa kukagesi, ukuvikelwa kwesekethe emfushane, ukuvikela ukugcwala kakhulu, nokuvikelwa kwe-voltage engaphansi.
Othintana nabo abasetshenziselwa ukulawula ukufakwa kwezibani zamandla aphezulu ngokuvamile bazohlelwa ngokucushwa kwe-latching, ukwehlisa ukusetshenziswa kwamandla sekukonke. Lolu hlelo lubandakanya amakhoyili amabili kagesi asebenza ndawonye. Ikhoyili eyodwa izovala izixhumi zesekhethi uma inikwe amandla kafushane futhi izivale ngozibuthe. Ikhoyili yesibili izowavula futhi uma isifakwe amandla. Lolu hlobo lokusetha luvame kakhulu ekuzishintsheni kwamahhovisi amakhulu, ukusetha izibani zezentengiselwano nezimboni. Umgomo ufana nendlela i-latching relay esebenza ngayo, nakuba yokugcina isetshenziswa kaningi kumasekhethi amancane anemithwalo encishisiwe.
Njengoba othintana nabo behloselwe ngokukhethekile lezi zinhlobo zezinhlelo zokusebenza zamandla kagesi aphezulu, bavame ukuba bakhudlwana ngokomzimba futhi babe namandla kakhulu kunamadivayisi ajwayelekile okushintsha i-relay. Kodwa-ke, izixhumi eziningi zikagesi zisaklanyelwe ukuthi zithwaleke kalula futhi zikhweleke futhi ngokuvamile zibhekwa njengezifaneleke kakhulu ukusetshenziswa ensimini.
Thumela Uphenyo NamuhlaKunezizathu eziningana zokuthi kungani i-contactor kagesi ingase ihluleke futhi idinge ukulungiswa noma ukushintshwa. Okuvame kakhulu ukushisela othintana naye noma ukunamathisela othintana naye, lapho abathintwayo bedivayisi babhajwe noma bahlanganiswe endaweni eyodwa.
Lokhu ngokuvamile kuwumphumela wamaza okugudluza ngokweqile, amandla okulawula angazinzile, izikhathi zoshintsho eziphansi kakhulu phakathi kwamandla aphezulu ngenxa nje yokuguga okuvamile. Lokhu kwakamuva kuvame ukubonakala njengokushiswa kancane kancane kwama-alloys amboza ama-contactterminals, okubangela ukuthi ithusi eliveziwe elingaphansi lishisene.
Esinye isizathu esivamile sokuxhumana okuhlulekayo ukushiswa kwekhoyili, okuvame ukubangelwa amandla kagesi amaningi noma anganele) kunoma yikuphi ukuphela kwekholomu kagesi. Ukungcola, uthuli, noma umswakama ongena esikhaleni somoya ozungeze ikhoyili nakho kungaba nomthelela.
Umehluko omkhulu phakathi kwe-AC contactor kanye ne-DC contactor ilele ekwakhiweni kwayo nasekwakheni. Izixhumi ze-AC zenzelwe amandla kagesi e-AC nezici zamanje, kuyilapho izixhumi ze-DC ziklanyelwe ngokuqondile amandla kagesi e-DC kanye nezamanje. Izixhumi ze-AC zivame ukuba zinkulu ngosayizi futhi zinezingxenye zangaphakathi ezihlukile zokusingatha izinselele zamanje ezishintshanayo.
Lapho ukhetha isixhumi se-AC, udinga ukucabangela izici ezifana ne-voltage nesilinganiso samanje sesistimu yakho ye-AC, izidingo zamandla omthwalo, umjikelezo womsebenzi, nanoma yiziphi izidingo ezikhethekile eziqondene nohlelo lokusebenza. Kunconywa ukuthi uthintane nemininingwane yomkhiqizi futhi uxhumane nomuntu osebenza ngogesi oqeqeshiwe noma unjiniyela ukuze ukhethe okufanele.
Basebenza Kanjani Oxhumana Nabo?
Ukuze uqonde kangcono ukuthi i-contactor isebenza kanjani, kuyasiza ukwazi mayelana nezingxenye ezintathu eziyinhloko zanoma iyiphi i-contactor kagesisidivayisi uma ihlangene. Lokhu kuvamise ukuba ikhoyili, abathintwayo, nendawo evalekile yedivayisi.
Ikhoyili, noma uzibuthe we-electromagnetic, iyisici esiyinhloko se-contactor. Kuya ngokuthi idivayisi isethwe kanjani, izokwenza isenzo esithile ekushintsheni abathintwayo (ibavule noma ibavale) uma ithola amandla.
Oxhumana nabo izingxenye zedivayisi ethwala amandla kuyo yonke isekethe eshintshwayo. Kunezinhlobo ezahlukene zoxhumana nabo ezitholakala koxhumana nabo abaningi, okuhlanganisa iziphethu namandla othintana nabo. Uhlobo ngalunye lwenza umsebenzi othile ekudluliseni i-current and voltage
I-contactor ebiyelwe enye ingxenye ebalulekile yedivayisi. Lena yindlu ezungeze ikhoyili noxhumana nabo, okusiza ukuvala izingxenye ezibalulekile ze-contactor. Indawo ebiyelwe ivikela abasebenzisi ekuthinteni ngephutha noma yiziphi izingxenye zeswishi, kanye nokunikeza isivikelo esiqinile ezingozini ezinjengokushisa ngokweqile, ukuqhuma, nobungozi bemvelo njengokungcola nokungena komswakama.
Isimiso sokusebenza se-contactor kagesi siqondile. Lapho ikhoyili ye-electromagnetic ine-current edlula kuyo kwakhiwa insimu kazibuthe. Lokhu kubangela ukuthi i-armature engaphakathi kwe-contactor ihambe ngendlela ethile mayelana nokuxhumana kukagesi
Kuya ngokuthi idivayisi ethile iklanywe kanjani kanye nendima ehloselwe lokhu ngokuvamile kuzoba ukuvula noma ukuvala abathintwayo.
Uma i-contactor yakhelwe ngendlela evamile evulekile (NO), okuthakazelisayo ikhoyili ene-voltage izophusha othintana nabo ndawonye, imise i-circuit, futhi ivumele amandla ukuba ageleze azungeze isekethe, Lapho ikhoyili iphelelwa amandla, othintana nabo bazovuleka, futhi isekethe izocisha. Yile ndlela othintana nabo abaningi abaklanywe ngayo
Oxhumana naye ovamise ukuvaleka (NC) usebenza ngendlela ehlukile. Isekhethi iphelile (othintana nabo bavaliwe) kuyilapho othintana naye ephelelwa amandla kodwa aphazamiseke (oxhumana nabo bavuliwe) noma nini lapho i-current inikezwa ku-electromagnetic, Lokhu ukucushwa okungajwayelekile okungajwayelekile kwabathintana nabo, nakuba kuyindlela evamile yokusethwa ehlukile yokushintsha okujwayelekile kokudlulisa.
Othintana nabo bangenza lo msebenzi wokushintsha ngokushesha, phezu kwezinkulungwane eziningi (noma izigidi) zomjikelezo phakathi nokuphila kwabo okugcwele kokusebenza.
