1. Sumo pfupi yemarelay
A relayiri anmagetsi ekudzora mudziyoiyo inoita yakafanotemerwa nhanho shanduko muhuwandu hunodzorwa mumagetsi ekubuda redunhu kana huwandu hwekupinza (excitation quantity) hunoshandurwa kuti huenderane nezvinodiwa.Iyo ine hukama hwekudyidzana pakati peiyo control system (inonzi zvakare inopinza reketi) uye inodzorwa system (inonziwo inobuda dunhu).Inowanzo shandiswa mumaseketi ekudzora otomatiki, ichokwadi "automatic switch" inoshandisa diki ikozvino kudzora kushanda kweiyo hombe ikozvino.Naizvozvo, inoita basa re otomatiki mutemo, kuchengetedzwa kwekuchengetedza uye shanduko yedunhu mudunhu.
2. Basa guru rekutumira
Relay chinhu chinoshandura otomatiki chine basa rekuzviparadzanisa nevamwe, kana shanduko yekunakidzwa muchikamu chekuisa inosvika pakukosha kwakatarwa, inogona kuita inobuda dunhu resimba rinodzorwa kune yakafanotemerwa nhanho shanduko mune otomatiki redunhu control mudziyo.Iyo ine nzira yekunzwa yekupindura kune ekunze excitation (yemagetsi kana isiri-yemagetsi), actuator kudzora "pa" uye "kubvisa" yedunhu rinodzorwa, uye yepakati kuenzanisa nzira yekuenzanisa, kutonga uye kushandura ukuru hweiyo. excitation.Relays anoshandiswa zvakanyanya mukudzora kure, telemetry, kutaurirana, otomatiki kudzora, mechatronics, uye aerospace tekinoroji kudzora, kuchengetedza, kutonga, uye kufambisa ruzivo.
Relays kazhinji ane induction meshini (chikamu chekupinza) chinoratidza zvimwe zvinosiyana zvekuisa (sezvino, voltage, simba, impedance, frequency, tembiricha, kudzvanywa, kumhanya, mwenje, nezvimwewo);an actuator (chikamu chinobuda) chinodzora dunhu rinodzorwa "pa" uye "kudzima";uye imwe yepakati mechaniki (drive part) iyo inoroora uye inoparadzanisa huwandu hwekupinda, inogadzirisa basa uye inotyaira chikamu chinobuda pakati pezvinopinza uye zvinobuda zvikamu.Pakati pezvinopinza uye zvinobuda zvikamu zveiyo relay, pane yepakati meshini (drive chikamu) iyo inoroora uye inoparadzanisa iyo inopinza, inogadzirisa basa uye inotyaira zvinobuda.
Sechinhu chekutonga, relay ine mabasa akati wandei.
(1) Kuwedzera huwandu hwekutonga: Semuenzaniso, multi-contact relay control siginecha inosvika kune imwe kukosha inogona kuchinjika, kuvhurwa uye kuvhurwa akawanda maseketi panguva imwe chete zvichienderana nemhando dzakasiyana dzemapoka ekusangana.
(2) Amplification: Semuyenzaniso, inonzwisa tsitsi relay, yepakati relays, nezvimwewo, ine shoma shoma yekudzora, unogona kudzora yakanyanya-simba redunhu.
(3) Masaini akabatanidzwa: Semuyenzaniso, kana akawanda masaini ekudzora achiiswa mune akawanda-anotenderera relay mune yakatemwa fomu, anofananidzwa uye akabatanidzwa kuti awane kufanotemerwa kudzora maitiro.
(4) Automatic, remote control, monitoring: Semuenzaniso, relays pane otomatiki zvishandiso, pamwe chete nezvimwe midziyo yemagetsi, inogona kuumba yakarongwa mitsara yekudzora, nekudaro ichigonesa otomatiki kushanda.
