Imigaqo yokwahlulahlula kunye nokwahlulahlula ii-contactors

Iicontactor zizinto ezibalulekileyo kwiinkqubo zombane kwaye zisetyenziselwa ukulawula ukuhamba kombane kwisekethe. Zisetyenziswa kwiindlela ezahlukeneyo zokusebenza, kubandakanya oomatshini bemizi-mveliso, iinkqubo zokufudumeza nezomoya, kunye nezixhobo zothutho. Iicontactor zahlulwe ngokohlobo lwamandla abawalawulayo. Iindidi ezimbini eziphambili zii-AC contactors kunye nee-DC contactors. Kweli nqaku, siza kuhlola imigaqo yokwahlulahlula kunye nokwahlulahlula ii-contactors, sigxile ngokukodwa kwii-AC contactors.

Izixhobo zokunxibelelana ze-ACzenzelwe ukulawula umsinga otshintshanayo (AC), ngokungafaniyo nee-contactors ze-DC, ezenzelwe ukulawula umsinga othe ngqo (DC). Umahluko phakathi kweentlobo ezimbini zee-contactors usekwe ikakhulu kwisekethe ephambili apho ziqhagamshelwe khona. Ukuba umsinga kwisekethe ephambili yi-AC, i-contactor yi-AC contactor nokuba i-voltage ye-coil yokulawula ingakanani na. Lo mgaqo wokwahlulahlula uqinisekisa ukuba ii-contactors ziyahambelana nohlobo oluthile lomsinga ezenzelwe ukuwulawula.

Kwicandelo le-AC contactor, kukho iintlobo ezimbini eziphambili: i-electromagnetic contactor kunye ne-vacuum contactor. Ii-electromagnetic AC contactors zisebenzisa iindlela ze-electromagnetic, iinkqubo zoqhagamshelwano, izixhobo zokucima i-arc kunye nezinto ezincedisayo ukulawula ukuhamba komsinga otshintshanayo kwisekethe ephambili. Umbindi we-AC contactor wenziwe ngamashiti esinyithi e-silicon alaminated, aluncedo ekunciphiseni ukulahleka komsinga we-eddy kunye ne-hysteresis okubangelwa kukutshintshana kwamasimi emagnethi. Ukongeza, kufakwa iringi yesekethe emfutshane ekupheleni kwe-iron core ukuze kupheliswe ukungcangcazela kunye nengxolo xa umsinga we-AC udlula zero, ukuqinisekisa ukusebenza okuthe tye nokusebenza kakuhle.

Ngokwahlukileyo koko, ii-vacuum contactors nazo ziwela kudidi lwe-AC contactor kwaye zenzelwe ukusetyenziswa kwamandla aphezulu. Ezi contactors zinesixhobo sokucima i-arc ye-ceramic esifakwe ngaphakathi esisebenza kakuhle kakhulu ekucimeni ii-arcs eziveliswa xa i-contactor itshintsha iisekethe ze-AC. Le teknoloji iphambili ivumela ii-vacuum contactors ukuba ziphathe imithwalo emikhulu ye-AC ngokuchanekileyo nangokuthembekileyo.

Xa ukhetha i-AC contactor yesicelo esithile, kubalulekile ukuqwalasela uhlobo kunye nomthamo womthwalo. Ukuba inkqubo yolawulo ikakhulu inemithwalo ye-AC kwaye i-DC motor okanye umthamo womthwalo we-DC mncinane, ii-AC contactors zingasetyenziselwa ulawulo. Nangona kunjalo, kubalulekile ukuqinisekisa ukuba umlinganiselo wangoku wee-contacts wanele ukuphatha umthwalo ngaphandle kweengxaki.

Ngamafutshane, imigaqo yokwahlulahlula kunye nokwahlulahlula ii-contactors idlala indima ebalulekileyo ekuqinisekiseni ukuhambelana kunye nokusebenza kakuhle kweenkqubo zolawulo lombane. Ii-contactors ze-AC zenzelwe ukulawula amandla e-AC kwaye ziyafumaneka kwiintlobo ezininzi ukuze zilungele amandla kunye nezicelo ezahlukeneyo. Ngokuqonda imigaqo yokwahlulahlula kunye nokukhetha i-contactor efanelekileyo yesicelo esithile, amashishini anokuqinisekisa ukusebenza kakuhle nangokuthembekileyo kweenkqubo zawo zombane. Nokuba ngoomatshini bemizi-mveliso, iinkqubo zokufudumeza kunye nezomoya, okanye izixhobo zothutho, ii-contactors ze-AC zizinto ezibalulekileyo zokusebenza kakuhle kunye nokhuseleko.

Iqela leMutai liqokelele amava angaphezu kweminyaka elishumi okuvelisa nokuthengisa kwi-iziphuli zesekethe, izixhobo zoqhagamshelwano, amandla amabiniiiswitshi zokudlulisela ngokuzenzekelayo (I-ATS) kunye neenkalo ezinxulumene noko. Silangazelela ithuba lokusebenza nani.
