I-contactor sisixhobo sombane esisetyenziswa ngokubanzi ekutshintsheni iisekethe kunye nokucima. Ngaloo ndlela, abafowunelwa bombane benza icandelo elingaphantsi lokutshintsha kwe-electromagnetic eyaziwa ngokuba zii-relays.
I-relay sisixhobo sokutshintsha esisebenza ngombane esisebenzisa icoil ye-electromagnetic coil ukuvula nokuvala iseti yabafowunelwa Esi senzo sikhokelela ekubeni amandla esekethi avule okanye avale ukuseka okanye ukuphazamisa isekethi). I-contactor luhlobo oluthile lwe-relay, nangona kukho ukungafani okubalulekileyo phakathi kwe-relay kunye ne-contactor.
Abafowunelwa ngokuyinhloko benzelwe ukusetyenziswa kwizicelo apho inani elikhulu langoku lifuna ukutshintshwa. Ukuba ujonge ingcaciso emfutshane yonxibelelwano lombane, ungathetha into efana nale ilandelayo:
I-contactor iyisixhobo sokutshintsha esilawulwa ngombane, esilungiselelwe ukuvula ngokuphindaphindiweyo kunye nokuvala isiphaluka, abaQhagamshelwano bavame ukusetyenziselwa izicelo eziphezulu zangoku ezithwalayo kunokuhanjiswa okuqhelekileyo, okwenza umsebenzi ofanayo kunye nokutshintsha okuphantsi kwangoku.
Khuphela iCatalog PDFI-contactor yombane isetyenziswe kwiimeko ezininzi apho kukho isidingo sokutshintsha amandla kwisekethe ngokuphindaphindiweyo. Njengokutshintsha kweerelay, ziyilelwe kwaye zakhelwe ukwenza lo msebenzi kumawaka amaninzi emijikelo.
Abanxibelelanisi bakhethwa ikakhulu kwizicelo zamandla aphezulu kunokuhanjiswa. Oku kungenxa yokukwazi kwabo ukuvumela amandla ombane aphantsi kunye nemisinga ukuba itshintshe. okanye umjikelo wamandla, amandla ombane aphezulu kakhulu/isekethi yangoku ivule okanye ivaliwe.
Ngokuqhelekileyo, i-contactor iya kusetyenziswa kwiimeko apho imithwalo yamandla kufuneka ivulwe kwaye ivaliwe rhoqo okanye ngokukhawuleza. Nangona kunjalo, zinokuthi ziqwalaselwe nokuba zibe namandla kwisekethe xa ivuliwe (ngokuqhelekileyo ivuliwe, okanye AKUKHO abafowunelwa), okanye ukuvala amandla kwisekethe xa ivuliwe (ngokuqhelekileyo ivaliwe, okanye abafowunelwa beNC).
Izicelo ezibini zeklasikhi ze-contactor zifana ne-motor starter yombane - njengazo zisebenzisa oonxibelelwano abancedisayo kunye nezixhumi zokusetyenziswa kwizithuthi zombane - nakwiinkqubo zokulawula izibane eziphezulu.
Xa i-contactor isetyenziswe njengesiqalo samagnetic kwi-motor yombane, ngokuqhelekileyo iya kunika uluhlu lwezinye iimpawu zokhuseleko ezifana ne-power-cutoff, ukukhusela isiphaluka esifutshane, ukukhuselwa komthwalo ogqithisiweyo, kunye nokukhusela ngaphantsi kombane.
Abafowunelwa abasetyenziselwa ukulawula ukufakwa kwezibane zombane ophezulu kuya kuhlala kucwangciswa kuqwalaselo lwelatching, ukuthoba usetyenziso lwamandla ngokubanzi. Eli lungiselelo libandakanya iikhoyili ezimbini ze-electromagnetic ezisebenza ngokudibeneyo. Ikhoyili enye iya kuvala abafowunelwa besiphaluka xa inikwe amandla ngokufutshane kwaye ibambe ivalwe ngombane. Ikhoyili yesibini iya kuzivula kwakhona xa inikwe amandla. Olu hlobo lokuseta luxhaphake ngakumbi kumatshini wokuzenzela kwiofisi enkulu, urhwebo kunye neshishini lokumisela izibane. Umgaqo ufana nendlela i-latching relay esebenza ngayo, nangona le yokugqibela isetyenziswa rhoqo kwiisekethe ezincinci ezinemithwalo encitshisiweyo.
Njengoko abafowunelwa benzelwe ngokukodwa ezi ntlobo zezicelo zombane ophezulu, zikholisa ukuba zikhulu ngokwasemzimbeni kwaye zomelele ngakumbi kunezixhobo zokutshintsha ii-relay eziqhelekileyo. Nangona kunjalo, uninzi lwabafowunelwa bombane luseyilwe ukuba luphatheke ngokulula kwaye lukhwele kwaye lubonwa lufanelekile kakhulu ukuba lusetyenziswe ebaleni.
Thumela uMbuzo namhlanjeKukho izizathu ezininzi zokuba kutheni i-contactor yombane inokusilela kwaye idinga ukulungiswa okanye ukutshintshwa. Eyona nto ixhaphakileyo kukudityaniswa kwe-welding okanye ukuncamathelisa koqhagamshelwano, apho abafowunelwa besixhobo baye baxinge okanye badityaniswe kwindawo enye.
Oku kudla ngokuba sisiphumo semisinga yokugxalathelana okugqithisileyo, amandla ombane angazinzanga, amaxesha aphantsi kakhulu otshintsho phakathi kwencopho ephezulu yangoku ngenxa yokuguga okuqhelekileyo kunye nokukrazuka. Oku kokugqibela kudla ngokubonakala njengokutsha ngokuthe ngcembe kweealloyi ezigquma izithinteli, okubangela ukuba ubhedu oluveziweyo olungaphantsi ludibane.
Esinye isizathu esiqhelekileyo sokusilela koqhagamshelwano kukutsha kweekhoyili, amaxesha amaninzi okubangelwa kumbane ogqithisileyo okanye ongonelanga) nakweliphi na isiphelo sekholi ye-electromagnetic. Ukungcola, uthuli, okanye ukungena kokufuma kwisithuba somoya esijikeleze ikhoyili nako kunokuba negalelo.
Umahluko ophambili phakathi koqhagamshelwano lwe-AC kunye ne-DC contactor ilele kuyilo nolwakhiwo lwabo. Abafowunelwa be-AC balungiselelwa amandla ombane we-AC kunye neempawu zangoku, ngelixa oonxibelelwano be-DC benzelwe ngokukodwa umbane we-DC kunye nowangoku. Abafowunelwa be-AC badla ngokuba nkulu ngokobungakanani kwaye banamacandelo ahlukeneyo angaphakathi ukujongana nemiceli mngeni yokutshintsha kwangoku.
Xa ukhetha umnxibelelanisi we-AC, kufuneka uqwalasele izinto ezinje ngevoltheji kunye nenqanaba langoku lenkqubo yakho ye-AC, iimfuno zamandla omthwalo, umjikelo womsebenzi, kunye naziphi na iimfuno ezikhethekileyo zesicelo. Kucetyiswa ukuba udibane neenkcukacha zomenzi kwaye udibane nombane oqeqeshiweyo okanye injineli yokhetho olufanelekileyo.
Basebenza njani abafowunelwa?
Ukuqonda kakuhle ukuba i-contactor isebenza njani, kuyanceda ukwazi malunga nezinto ezintathu eziphambili zaso nasiphi na isixhobo sombanesisixhobo xa sidityanisiwe. Ezi zidla ngokuba yikhoyili, abafowunelwa, kunye nendawo ebiyelweyo yesixhobo.
Ikhoyili, okanye i-electromagnetic, yinxalenye ephambili ye-contactor. Ngokuxhomekeke kwindlela isixhobo esisetwa ngayo, siya kwenza isenzo esithile kubafowunelwa bokutshintsha (ukuvula okanye ukuvala) xa sifumana amandla.
Abafowunelwa ngamacandelo esixhobo esithwala umbane kwisekethe sitshintshwa. Kukho iintlobo ezahlukeneyo zoqhagamshelwano ezifunyenwe kubafowunelwa abaninzi, kubandakanywa imithombo kunye noqhagamshelwano lwamandla. Uhlobo ngalunye lwenza umsebenzi othile ekudluliseleni i-current and voltage
I-enclosure yoqhagamshelwano yenye inxalenye ebalulekileyo yesixhobo. Le yindlu ejikeleze ikhoyili kunye nabafowunelwa, inceda ukugquma amacandelo angundoqo oqhagamshelwano. Indawo ebiyelweyo ikhusela abasebenzisi ekuchukumiseni ngempazamo naziphi na iindawo zokutshintsha, kunye nokubonelela ngokhuseleko oluluqilima kwimingcipheko enjengokushisa, ugqabhuko-dubulo, kunye nobungozi bokusingqongileyo njengobumdaka kunye nokungena kokufuma.
Umgaqo wokusebenza we-contactor yombane uqondile. Xa i-coil ye-electromagnetic ine-current edlula kuyo i-magnetic field iyadalwa. Oku kubangela ukuba i-armature ngaphakathi kwe-contactor ihambe ngendlela ethile malunga noqhagamshelwano lombane
Kuxhomekeke kwindlela isixhobo esithile senziwe ngayo kunye nendima ekujoliswe kuyo oku kuya kuba kukuvula okanye ukuvala abafowunelwa.
Ukuba i-contactor yenzelwe njengesiqhelo evulekileyo (NO), i-coil enomdla kunye ne-voltage iya kutyhala abafowunelwa kunye, iseke isiphaluka, kwaye ivumele amandla ajikeleze isiphaluka, Xa i-coil i-de-energized, abafowunelwa baya kuvulwa, kwaye isiphaluka siya kucima. Le yindlela abaninzi abafowunelwa abayilwa ngayo
Umnxibelelanisi oqhelekileyo ovaliweyo (NC) usebenza ngendlela eyahlukileyo. Isekethe igqityiwe (abafowunelwa bavaliwe) ngelixa umnxibelelanisi ecinywa amandla kodwa ephazamisekile (abafowunelwa bavulekile) nanini na xa ikhoyo inikwa i-electromagnetic, Olu luqwalaselo olungaxhaphakanga kakhulu lwabafowunelwa, nangona luseto oluqhelekileyo oluqhelekileyo lokutshintsha okusemgangathweni.
Abafowunelwa banokuwenza ngokukhawuleza lo msebenzi wokutshintsha, ngaphezulu kwamawaka amaninzi (okanye izigidi ngokwenene) zemijikelo ngexesha lokuphila kwabo ngokupheleleyo.
