I-AC contactor isetyenziswa ngokubanzi kwisekethe ye-voltage ephantsi, luhlobo losetyenziso olukhuselekileyo, ulawulo olulula, isixa esikhulu kunye noluhlu olubanzi lwezinto ezifunekayo kwimizi-mveliso. ngaphezu kwezigidi ezili-100 zeemitha, inkqubo yayo ye-electromagnetic esebenzayo ekufunxeni ukusetyenziswa kwamandla asebenzayo phakathi kwe-8w-100w.Amandla asebenzayo asetyenzisiweyo aphakathi kwamatyala amaninzi kunye namakhulu ebhilidi. Ukuhanjiswa kwamandla asebenzayo asetyenzisiweyo kuqikelelwa kwi-65% ~ 75% yentsimbi. i-core, i-short circuit ring 25% ~ 30%, 3% ~ 5% coil.Ngokujonga ingxaki yokusetyenziswa kwamandla amakhulu ekusebenzeni kwee-contactors ze-AC, ekuqaleni kwe-1981, uxwebhu lwesizwe lokukhululwa no.I-56 ibonise ukuba amanyathelo okugcina amandla oqhagamshelwano lwe-AC kufuneka aphunyezwe.Emva kophando lwexesha elide, ezinye iimpumelelo zokulondoloza amandla ziye zafezwa, kodwa isakhiwo sabafowunelwa bendabuko sihlaziywe kakhulu, inkqubo inzima, kunye neendleko zokuvelisa. ukwanda.Imveliso egqityiweyo iyabiza, okanye uluhlu lokusetyenziswa luncinci, okanye aluhambelani nemikhwa yokusetyenziswa kwabantu, kwaye ezinye zichaphazela ukuthembeka kwayo kwiidigri ezahlukeneyo, ezinokuba sesona sizathu sokuba imveliso yogcino lwamandla ingakhange ibekho. yamkelwe ngokubanzi yimarike.
1 Iindlela ezininzi eziqhelekileyo zokonga umbane zabafowunelwa be-AC kwimarike kunye nezibonelelo zabo kunye nokungalunganga:
Umgaqo osebenzayo wesixhobo esitsha sokugcina amandla soqhagamshelwano
Isixhobo sokugcina amandla sinesixhobo sokukhubeka simahla, sisebenzisa umgaqo wokutshixa ikhonkco le-crank (vula kuphela i-0.15N-0.3N amandla), isixhobo sibambekile, senze umazibuthe woqhagamshelwano unokugcina onke amaqela oqhagamshelwano ngaphandle kokusetyenziswa kwamandla, uvule injongo ukonga amandla;ngenxa yokuba i-lock mechanical lock, ubomi bayo abunakuba phezulu kakhulu, malunga namaxesha angama-35,000, ngoko isetyenziselwa kwiimeko zokusebenza eziqhubekayo, ezifana nefeni yokulawula, ipompo kunye nekhabhinethi yembuyekezo ye-capacitor.Umgaqo wokusebenza ulandelayo:
Isixhobo sokugcina amandla siqhagamshelwe kumnxibelelanisi, kubandakanywa nendlu, intonga yokuqalisa, isixhobo sokukhubeka simahla, ngokuqhelekileyo kuvalwe i-micro switch, intonga, icoil yokonga amandla kunye nendibano yebhanti ye-electromagnetic. Umgaqo wokutshixa, umatshini ubambekile ngokuqinileyo, i-micropower electromagnetic buckle component core suction extrusion micro switch, yenza unxibelelwano oluhlala luvaliwe oluncinci luhlala luvaliwe kunxibelelwano oluhlala luvulekile, ikhoyili yamandla oqhagamshelwano, i-electromagnetic buckle ngaphandle kokusetyenziswa kwamandla isenakho ukugcina konke ukusebenza. imeko yeqela loqhagamshelwano, yangoku kuphela ukusuka kwikhoyili yokonga amandla.Xa isignali yolawulo isetyenziswa ngesiquphe okanye igridi yamandla isilela ngesiquphe, i-micropower yosetyenziso lwe-electromagnetic tripping component ityhala ikhonkco ukuqhawula uqhagamshelo lwesixhobo sokukhubeka simahla, kunye nelever yokuqalisa iyabuya. ukuya kwindawo yokuqala phantsi kwe-contactor counterforce spring.Ngenxa yokuba i-micro-power consumption electromagnetic unbuckle component efunekayo ukuze uvule amandla amancinci kakhulu angenza ukuvula i-electromagnetic, ukufezekisa injongo yokonga amandla.
Umzobo 1 ngumzobo weprofayili womnxibelelanisi okanye isixhobo esikhethekileyo sokugcina amandla kunye ne-contactor okanye i-relay.
IKHIWANE.I-2 yidayagram yoxhulumaniso lwesiphaluka kwisixhobo esikhethekileyo sokugcina amandla kunye ne-contactor okanye i-relay.
3. Iimpawu zesixhobo esisanda kuphuhliswa esikhethekileyo sokugcina amandla kubafowunelwa
3.1 Akukho ukusetwa kwakhona ngesandla: igridi yamandla ivaliwe ngokukhawuleza, isekethe ephambili iya kunqunyulwa ngokuzenzekelayo, ngaphandle kokusetha kwakhona ngesandla;
3.2 Umsebenzi wokudibanisa oomatshini uqinisekisa ukhuseleko kunye nokuthembeka kweemveliso
Isixhobo sikwaxhotyiswe ngomsebenzi wokudibanisa oomatshini, ukuba isitshixo asiyigxininisi i-coil, i-coil kwi-contactor ayiyi kucinywa, ukwenzela ukuba uqhagamshelwano oluphambili luqhubeke luvaliwe, ngoko ke ukuba isixhobo asikwazi ukusetyenziswa ngokuthembekileyo. okanye yonakele, ayiyi kuchaphazela ukusetyenziswa okuqhelekileyo kwe-contactor ye-original, kodwa imveliso ayisekho ukugcina amandla.
3.3 Akukho mbane wokuncedisa ofunekayo
Njengoko kuboniswe kwi-Figure 3, isixhobo sokugcina amandla asidingi ukunikezelwa kombane oncedisayo, kunye nokunikezelwa kombane oyintloko, kwaye unokongeza iqhosha lokumisa ukulawula kude umnxibelelanisi, kungekho mngcipheko wokhuseleko.
3.4 Iplagi kwaye Dlala
Isixhobo sokugcina amandla sixhonywe ngokuthe ngqo kwiimveliso zoqhagamshelwano, i-contactor endala okanye i-relay ingasetyenziselwa ngaphandle kokuguqulwa;ukufakwa lula, uluhlu olubanzi lokusetyenziswa.
3.5 Ukusebenza okuphezulu kunye nokonga amandla ngaphezu kwe-90%
Xa isetyenziswa kunye nesixhobo, i-AC yoqhagamshelwano engundoqo ayivelisi ukuxutywa kwexesha, akukho ngcangcazelo, ngoko akukho ngxolo, inokunciphisa kakhulu ukusetyenziswa kwamandla, ukugcinwa okulula, ukunciphisa ngokufanelekileyo iindleko zokusebenza.
3.6 Ayichaphazeli i-original contactor function, kodwa kunokongezwa nabanye oonxibelelwano abancedisayo
Musa ukuhlala unxibelelwano oluncedisayo lwangaphambili, kodwa kwakhona ngokwesidingo, uyilo lokongeza uqhagamshelwano oluncedisayo, umsebenzi wokulibaziseka kunye ne-capacitor isixhobo esikhethekileyo sokugcina amandla, ukuze ube nemisebenzi eyahlukeneyo.
3.7 Inokwandisa umsebenzi wombane ochasene ne-sway
Esi sixhobo sinomsebenzi othile wokulibaziseka, ukusombulula ngempumelelo ingxaki "yokugubha umbane". Okwangoku, phantsi kweemeko ezifanayo, ubomi boqhagamshelwano lwe-AC contactor yokulondoloza amandla kunye ne-AC contactor yendabuko yanda ngamaxesha angama-3-5, ukunciphisa ukusebenza. kunye neendleko zokugcina.
3.8 Uluhlu olubanzi lwamandla ombane
Ukufunxa i-voltage ebanzi 0.8-1.1US, i-voltage yokukhulula i-20% ~ 75% yase-US, i-AC-DC yoqhagamshelwano jikelele.
