Current relays - the siyana uye mudziyo

Current ataure - zano kuti inowanzoshandiswa kuti chiratidzo kuitika kwazvo mumwe inodzorwa redunhu. Uyewo, rinoshandiswa chokukuvadza redunhu iri chiitiko pfupi matunhu kana overloads. Undercurrent relays anoshandiswa ndoda kakawanda. Kwakadaro mano zvakagadzirirwa vaibvisa zvemagetsi redunhu kana imwe ivavo kuitika ukoshi.

Kune mhando dzakawanda akasiyana nemagetsi mano akadai simba haizoshandisi. Vakasiyana rokuvaka uye uchishandisa mazano. Kana isu kutaura pamusoro inonzi dzekare Chishandiso, ndiko chinjwa chikepe pamusoro namatsime, izvo anodzora vokukurukura uye coils chinoumba (kazhinji simbi). Kana ano inopfuura nomunyika coils pave remagineti womumwe zvikuru. About chiito ichi remagineti ndiro magnetized uye coils chinoumba anotanga uwane armature. Nokudaro, neshamwari achange kukonzerwa.

The Coil of mudziyo unotora munhu windings shoma, asi ane guru dhayamita waya (kusiyana, semuenzaniso, zvakafanana voltage relays). The dhayamita of waya kunobva magetsi, kana kupfuura zvazviri, kwakakura nokukosha ano kukosha. Izvi inowana munhu voltage donhwe. Izvi zvinokosha zvikuru nokuti coils zvakabatana muna dzaitevedzana kune varikutonga remudunhu.

Vamwe DC relays vane chinjika rwendo ano. Kazhinji, izvi zvinoitwa kuchinja armature chitubu makakatanwa. Ataure AC, rinoshandiswa kudzora dzakakwirira dzenzvimbo zvinogona kuitwa kuburikidza transformers.

Anokosha chinoratidza mudziyo urwu runodzivirira ndiyo nguva mhinduro. Mano ichi mhando inogona kushandiswa kudzivirira nematunhu pfupi vane nokuchinja nguva isina kupfuura wandei makumi ezviuru milliseconds.

Solid mamiriro ataure DC mudunhu anoita kunonoka kana akochonorwa. Izvi anobvisa mukana positives zvenhema kune pfupi-nguva ano kunowedzera. zano kwakadaro kazhinji ane kudzora uchishandisa nguva.

Chimwe ndicho mhando anodzivirira mano ndiyo chafariz ataure ano. Iri bimetallic mundiro, akapa vane kudziyisa Kufananidzira wakaitwa zvinhu rurefu resistivity (semuenzaniso, nichrome). The ndiro rinoumbwa zvinhu nedzimwe coefficient pamusoro chafariz kuwedzera, izvo anokotama pamusoro kudziyisa uye anoita pamusoro chinja mashandiro. Mhinduro nguva zano yakadaro kunobva magetsi - dzakanga ndiro, zvikuru nokukurumidza kudziyirwa kumusoro mundiro, uye vashoma nguva mhinduro.

Wemagetsi overcurrent ataure kushandiswa rakada nguva imwe zadzisa igumburwe. zvemagetsi ataure redunhu anogona dzinoona anonongedzera achitevedza zvakafanorongwa parameters uye maitiro pachine. Unogona akaisa zvinobvumidzwa kunonyanyisa kuitika uye nguva kunonoka kana nokuzviparadzanisa. iyezvino relays kwakadaro kunogona kuva variables uye constants. mano aya kazhinji kuuya muchimiro yakavakwa-kuna mano mazhinji.
