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 michina interlock inofanirawo kushandiswa munzvimbo dzakaomarara zvinodiwa. reserves kupinda mumwe kudzora loop uye kukiya mumwe nomumwe, kuitira kuti vaviri vanobatana havagoni kubatanidzwa panguva imwe chete. Ichi loop iri nyore, mukuru musimboti ndeyekuvimbisa kuti motokari iri reverse haigoni kuva pa, uye reverse haisi nyore. pa, zvikasadaro kuyamwa kubata kuchaita matatu nhanho ac pasi peiyo contactor fomu pfupi dunhu, saka kukiya muchiuno, pane kana reverse kana kutendeuka zvinodiwa zvinogona kumisa mota kushanda chero nguva, saka mira bhatani kune akateedzana, tanga kuve mukati. parallel.

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 mameta eKM2 akabatana muKM coil loop. Kana KM iri kushandura magetsi, KM2 haigone kuwana magetsi, kudzivirira njodzi dzenguva pfupi.
