Chii Chinonzi Current Transformer?
Atransformer yemazuva anomudziyo unoshandiswa mumagetsi kuyera kufamba kwemagetsi. Unoshanda nekudzika simba remagetsi rakakwirira kusvika padanho rakaderera uye rakachengeteka. Izvi zvinobvumira mamita nemidziyo kutarisa simba remagetsi pasina kusangana nemagetsi ane njodzi. Transformer yemagetsi ine winding yekutanga uye winding yechipiri. Kutenderera kwekutanga kunobatanidza nedunhu guru, nepo winding yechipiri ichibatanidza nemidziyo yekuyera. CT inobatsira kuchengetedza michina uye inoita kuti kuverenga kwakarurama kuve kwakarurama. Masisitimu mazhinji emagetsi anovimba ne transformer yemagetsi kuti ishande zvakachengeteka uye zvakavimbika.
Chinangwa cheCT muPower Systems
Iyo ct inoita mabasa akakosha mumagetsi emazuva ano. Yakakosha pakutarisa nekudzora network dzemagetsi. Heano mashandisirwo makuru e transformer yemagetsi:
- Kuyerwa Kwazvino: Iyo ct inobvumira vashandisi kuteedzera mashandisirwo esimba uye kutarisa mashandiro esystem.
- Dziviriro: Iyotransformer yemazuva anoinoita kuti ma "protective relay" aone zvikanganiso. Kana pakaitika dambudziko, "ct" inobatsira kutanga zviito zvinodzivirira kukuvara kwemidziyo.
- Kuzviparadzanisa: Chishandiso ichi chinodzikisa magetsi kusvika padanho rakachengeteka. Izvi zvinodzivirira vashandi uye zvinoita kuti kugadzirisa kuve nyore.
Zano: Kushandisa transformer yemagetsi yemhando yepamusoro kunovandudza kuchengetedzeka uye kururama mumasisitimu emagetsi. Midziyo yemagetsi yakavimbika inobatsira kuchengetedza kushanda kwakasimba uye kuderedza njodzi.
Chishandiso (A ct) chikamu chakakosha chemagetsi. Chinotsigira kuyerwa uye dziviriro, zvichiita kuti chive chakakosha pakushandisa simba zvakanaka.

Nheyo yekushanda yeCurrent Transformer
Transformer yemagetsi inoshanda nekushandura magetsi epamusoro kuita magetsi echipiri akaenzana. Nheyo yekushanda inoshanda kuburikidza ne electromagnetic induction. Kana magetsi achichinjana achipfuura nemu core winding, anogadzira simba remagineti mu core yesimbi ine laminated. Field iyi inokonzera voltage mu secondary winding. Secondary current inomiririra magetsi epamusoro, asi padanho rakaderera uye rakachengeteka. Zvinhu zvinodzivirira ma windings ne core, zvichiita kuti zvishande zvakanaka.
Chiyero che ct chinotsanangura hukama huripo pakati pemagetsi ekutanga neechipiri. Semuenzaniso, kana chiyero che ct chiri 100:5, 100 amperes mudunhu rekutanga ichagadzira 5 amperes mudunhu rechipiri. Kuchinja uku kweproportional kunobvumira kuyerwa kwakarurama nekuchengetedzwa mumasisitimu emagetsi.
Zvinhu zvinoshandiswa mukati mesimbi nepamawinding zvinokanganisa mashandiro. Simbi yesilicon inopa simba remagineti rakakwira uye kurasikirwa kwakaderera, zvichiita kuti ive yakakodzera kutamiswa kwesimba remagineti zvinobudirira. Ferrite ceramics inopa insulation yakanaka uye inoderedza eddy currents, yakakodzera kushandiswa kwe high-frequency. Laminated magnetic cores inoderedza eddy current effects, nepo carbonyl iron inoramba yakagadzikana pakupisa kwakasiyana-siyana.
Cherechedza: Chinoshandura magetsi cheMaliotech LMZ Series chinoshandisa zvinhu zvepamusoro uye dhizaini kuti chiwane kunyatsojeka uye kuvimbika pakuyera. Kugadzirwa kwacho kwakasimba kunovimbisa kushanda kwakasimba munzvimbo dzinoda simba.
