Ko contactor interlock sei?

Interlock ndeyekuti vaviri vanobatana havagone kubatikana panguva imwe chete, iyo inowanzo shandiswa mumotokari yakanaka uye reverse redunhu.Kana macontactor maviri akabatanidzwa panguva imwe chete, dunhu pfupi pakati pechikamu chemagetsi chichaitika.

Iyo yemagetsi inovharika ndeyekuti anowanzo kuvharika ma contacts eKM contacts akabatana mucoil loop yeKM contacts, uye anowanzo kuvharika ma contacts eKM contacts akabatana munhevedzano mu coil loop inodiwa paKM1 contact.Zvisinei, kana munhu wekubata ari welded, iyo yemagetsi interlock inokundikana.Naizvozvo, contactors ane michini interlock inofanirawo kushandiswa munzvimbo dzakaomarara zvinodiwa.Two contactors kupindira dzavo dzakabatana mubatsiri kazhinji akavhara kuonana reserves kupinda mumwe kudzora loop uye kukiya mumwe nomumwe, kuitira kuti vanobatana vaviri havagoni. batanidza panguva imwe chete.Ichi loop iri nyore, chirevo chikuru ndechekuona kuti mota iri reverse haigone kuve, uye reverse haisi pa, zvikasadaro kubatwa kuchaita matatu phase ac pasi peiyo contactor fomu pfupi redunhu, saka kukiya muchiuno, pane kana reverse kana kutendeuka zvinodiwa zvinogona kumisa kushanda kwemota chero nguva, saka mira bhatani kunhevedzano, tanga kuenderana.

Aya ndiwo maviri macontactor KM1, KM2 control motor positive-reversal circuit.Kana KM1 neKM2 vachiita panguva imwe chete, ivo vachanyatsopfupisa kupfupisa dunhu guru uye kukonzera tsaona.Naizvozvo, iyo inowanzovharwa ma contacts eKM1 akabatana munhevedzano. muKM2 coil loop, uye anowanzo kuvharwa macontacts eKM2 akabatanidzwa muKM coil loop. Kana KM ichishandura magetsi, KM2 haigone kuwana magetsi, kudzivirira nenzira kwayo tsaona dzenguva pfupi.
