Chiyambi cha inductance

1. Mawonekedwe a koyilo ya DC relay ndi yayikulu ndipo pano ndi yaying'ono. Zikanenedwa kuti sizidzawonongeka zikalumikizidwa ndi makina osinthira, zimatulutsidwa nthawi yake. Komabe, kachitidwe ka koyilo ya AC relay ndi yaying'ono, ndipo pano ndi yayikulu. Kulumikiza DC kudzawononga koyilo.

2. Padzakhala lalifupi dera mphete pa chitsulo pakati pa AC contactor, koma osati DC contactor. Waya awiri a koyilo ya DC ndi yopyapyala, chifukwa pano ndi yofanana ndi U/R, ndipo sikusintha. Waya awiri a koyilo ya AC ndi wandiweyani, chifukwa koyiloyo imakhala ndi inductance, ndipo zomwe zikuchitika zikusintha kwambiri zisanachitike komanso pambuyo pake zida zimakopeka. Ngati chombocho chikakamira ndipo sichikukopa, chimawotcha koyilo. Pakatikati pachitsulo cha AC koyilo iyenera kugwiritsa ntchito chitsulo cha silicon, ndipo pachimake chitsulo cha DC koyilo chitha kugwiritsa ntchito chipika chonse chachitsulo.

3. Zokopa ndi zamakono za AC electromagnet zikusintha, zonse zomwe zimakhala zazikulu kumayambiriro kwa kukopa, koma zing'onozing'ono pambuyo pa kukopa. Komabe, kukopa ndi maginito amagetsi a DC kumakhalabe kosasinthika panthawi yonse yokopa ndikugwira.

4. Ma coil a AC samasinthidwa, pomwe ma coil a DC amakhala ndi polarized. Mfundo zawo zogwirira ntchito ndizofanana. Onse amapanga mphamvu ya maginito mu koyilo kuti achitepo kanthu. Kusiyana kwake ndikuti ma coil a AC amapanga maginito osinthasintha, omwe amakhudzidwa kwambiri ndi magetsi komanso apano, pomwe ma coil a DC amakhala okhazikika komanso amakhala ndi chitetezo chapamwamba, chomwe chili choyenera kwambiri pakugwira ntchito nthawi yomweyo.

M'malo mwake, koyilo yojambulira opanda zingwe imakhala ndi inductance yayikulu komanso yocheperako yotayikira, ndipo moyo wake wautumiki ndi wautali kuposa inductance wamba. Ndikukhulupirira kuti aliyense akudziwa kuti miyezi isanu ndi umodzi ndi nthawi ya inductance, koma cholumikizira chopanda zingwe chopanda zingwe chimadalira momwe amapangira komanso malo osungira. Koyilo yojambulira opanda zingwe yadutsa mayeso othana ndi oxidation ndi kupopera mchere musanachoke kufakitale kuti muwonetsetse kuti chinthucho chikuwotcherera kwambiri. Chikwama chilichonse chaching'ono cholongedza ndi bokosi lamkati limasindikizidwa ndikuyikidwa ndi desiccant, kotero nthawi yosungiramo imatha kupitilira miyezi isanu ndi itatu. Komanso, ferrite zakuthupi wakhala sintered pa kutentha madigiri oposa 1000, choncho ali ndi mphamvu mkulu ndipo akhoza kutsimikizika kwamuyaya.
