1. Chidule chachidule cha ma relay
A kutumizandi achipangizo chowongolera magetsizomwe zimapanga kusintha kokonzedweratu kwa kuchuluka komwe kumayendetsedwa mugawo lamagetsi amagetsi pomwe kuchuluka kwa zolowetsa (kuchuluka kwachisangalalo) kumasinthidwa kuti zikwaniritse zofunikira.Ili ndi mgwirizano wolumikizana pakati pa dongosolo lowongolera (lomwe limatchedwanso gawo lolowera) ndi dongosolo loyendetsedwa (lomwe limatchedwanso gawo lotulutsa).Kaŵirikaŵiri amagwiritsidwa ntchito m'mabwalo odziwongolera okha, kwenikweni ndi "kusintha kwadzidzidzi" komwe kumagwiritsa ntchito kamphindi kakang'ono kuti azitha kuyendetsa magetsi akuluakulu.Choncho, amasewera udindo wa malamulo basi, chitetezo chitetezo ndi kutembenuka dera mu dera.
2. Udindo waukulu wa ma relay
Relay ndi chinthu chosinthira chokha chokhala ndi ntchito yodzipatula, pamene kusintha kwachisangalalo mu gawo lothandizira kufika pamtengo wotchulidwa, kungapangitse kuti dera lozungulira la mphamvu yolamulidwa likhale lokonzekeratu kusintha kwa chipangizo chowongolera dera.Lili ndi makina omveka kuti ayankhe ku chisangalalo chakunja (chamagetsi kapena osakhala amagetsi), actuator kuti azilamulira "pa" ndi "kuchoka" kwa dera loyendetsedwa, ndi njira yofananira yapakatikati kuti ifananize, kuweruza ndi kutembenuza kukula kwa magetsi. chisangalalo.Ma relay amagwiritsidwa ntchito kwambiri poyang'anira, kuteteza, kuwongolera, ndi kutumiza zidziwitso.
Ma relay nthawi zambiri amakhala ndi makina olowetsa (gawo lolowetsa) lomwe limawonetsa zosintha zina (monga zapano, voteji, mphamvu, zolepheretsa, ma frequency, kutentha, kuthamanga, liwiro, kuwala, ndi zina);actuator (gawo lotulutsa) lomwe limayendetsa dera loyendetsedwa "pa" ndi "kuzimitsa";ndi makina apakatikati (gawo loyendetsa) lomwe limagwirizanitsa ndikulekanitsa kuchuluka kwa zomwe zalowetsedwa, zimayendetsa ntchitoyo ndikuyendetsa gawo lotulutsa pakati pa zolowetsa ndi zotulutsa.Pakati pa zolowetsa ndi zotulutsa za relay, pali njira yapakatikati (gawo loyendetsa) lomwe limagwirizanitsa ndikulekanitsa zolowa, zimayendetsa ntchitoyo ndikuyendetsa zotuluka.
Monga chinthu chowongolera, relay ili ndi maudindo angapo.
(1) Kukulitsa mtundu wowongolera: Mwachitsanzo, chizindikiro chowongolera ma relay angapo mpaka pamtengo wina ukhoza kusinthidwa, kutsegulidwa ndikuyatsa mabwalo angapo nthawi imodzi molingana ndi mitundu yosiyanasiyana yamagulu olumikizana.
(2) Kukulitsa: Mwachitsanzo, ma relay omvera, ma relay apakatikati, ndi zina zambiri, ndi kuwongolera kochepa kwambiri, mutha kuwongolera dera lamphamvu kwambiri.
(3) Zizindikiro zophatikizika: Mwachitsanzo, zizindikiro zowongolera zambiri zikadyetsedwa munjira yolumikizirana mosiyanasiyana, zimafaniziridwa ndikuphatikizidwa kuti zikwaniritse zomwe zidakonzedweratu.
(4) Automatic, remote control, monitoring: Mwachitsanzo, ma relay pazida zodziwikiratu, pamodzi ndi zida zina zamagetsi, zimatha kupanga mizere yowongolera, motero kupangitsa kuti zizigwira ntchito zokha.
