Munzvimbo yeinjiniya yemagetsi, ma transformer anoita basa rakakosha mukufambisa nekugovera simba remagetsi. Pakati pemhando dzakasiyana-siyana dzevashanduri, vashanduri vemazuva ano (CTs) uye magetsi emagetsi (PTs) ndiwo maviri anonyanya kushandiswa. Pasinei nemazita avo akafanana, anoshumira zvinangwa zvakasiyana uye akabatanidzwa kune zvakasiyana-siyana zvemagetsi emagetsi. Ichi chinyorwa chinotarisa mune izvo zvino shandurudzo uye magetsi emagetsi anoshandiswa, uye anosimbisa chinangwa chikuru chezvino shanduko.
Chii chinonzi aCurrent Transformer?
Azvino transformer imhando yechiridzwa cheshanduko chakagadzirirwa kuyera alternating current (AC). Inoshanda nekugadzira yakaderedzwa ikozvino yakanyatsoenderana neyazvino iri mudunhu, iyo inogona kubva yakachengeteka kuongororwa uye kuyerwa neyakajairwa zviridzwa. CTs inokosha mumamiriro ezvinhu apo mazinga emazuva ano akanyanya kukwirira kuti aonekwe zvakananga nemidziyo yakajairika.
Chinangwa Chikuru cheShanduro Yazvino
Chinangwa chekutanga cheshanduko yazvino ndeyekufambisa kuyerwa kwakachengeteka uye kutariswa kwemazinga epamusoro azvino. Nekudzika pasi ikozvino kusvika kune yakaderera, inogoneka nhanho, CTs inobvumira kushandiswa kweyero yekuyera zviridzwa uye inodzivirira relays. Izvi zvakakosha kune zvikonzero zvinotevera:
Safety:Kuyera zvakananga mafungu akakwirira kunogona kuva nengozi. CTs inoderedza ikozvino kusvika kune yakachengeteka, kuderedza ngozi kune vashandi nemidziyo.
Kururama:CTs inopa zviyero zvazvino, izvo zvakakosha pakushanda kwakaringana kwekudzivirira relay uye metering zvishandiso.
Kuiswa kwemurwere kwake ega:Vanopa magetsi ega ega pakati pe-high-voltage simba redunhu uye yekuyera zviridzwa, kudzivirira iyo yekupedzisira kubva kune yakakwira-voltage surges.
Zvishandiso zvezvino Transformers
Current transformersanoshandiswa zvakanyanya mumhando dzakasiyana dzekushandisa, kusanganisira:
Simba System Dziviriro:CTs inobatanidzwa mukushanda kwekudzivirira relays, iyo inoona zvikanganiso uye inotanga mavhiriki ematunhu kuti aparadzanise zvikamu zvisina kunaka.
Metering:Iwo anoshandiswa mumamita emagetsi kuyera huwandu hwesimba remagetsi rinopedzwa.
Monitoring:CTs inobatsira mukutarisa kuyerera kwemazuva ano mumasisitimu emagetsi, zvichiita kuti kuonekwe kwekuremerwa uye kuve nechokwadi chekugovera simba kwakasimba.
Chii chinonzi aSimba Transformer?
Simba rinoshandura, kune rumwe rutivi, rakagadzirirwa kufambisa simba remagetsi pakati pemaseketi maviri kana anopfuura kuburikidza nemagetsi induction. Magetsi emagetsi anoshandiswa kukwira (kuwedzera) kana kudzika pasi (kuderera) mazinga emagetsi mumasisitimu emagetsi, kufambisa kufambiswa kwakanaka uye kugovera kwesimba remagetsi pamakiromita marefu.
Chinangwa chikuru cheSimba Transformer
Chinangwa chikuru cheshanduro yemagetsi ndechekugonesa kufambiswa kwakanaka kwemagetsi emagetsi kubva kune zviteshi zvekugadzira kusvika kune-vashandisi vekupedzisira. Izvi zvinosanganisira:
Voltage Regulation: Magetsi emagetsi anogadzirisa voltage mazinga kuti aderedze kurasikirwa kwesimba panguva yekufambisa. High voltages anoshandiswa kuendesa kure-kure kurerutsa ikozvino uye, nekudaro, kurasika kurasikirwa.
Kugovera Kwemutoro: Ivo vanobatsira mukugovera mitoro yemagetsi pamasekete akasiyana, kuve nechokwadi chepakati uye yakagadzikana magetsi ekupa.
Kuzviparadzanisa nevamwe: Magetsi emagetsi anopa kuparadzaniswa kwemagetsi pakati pezvikamu zvakasiyana zvesimba remagetsi, kuwedzera kuchengetedzeka uye kuvimbika.
Zvishandiso zveSimba Transformers
Magetsi emagetsiakakosha mumatanho akasiyana emagetsi emagetsi, kusanganisira:
Zviteshi zveGeneration: Vanokwidza voltage inogadzirwa nemagetsi emagetsi kuitira kutapurirana kureba.
Zviteshi: Magetsi emagetsi ari muzviteshi zvishoma anodzika mavhiri ekutapurirana akakwira kusvika pamazinga akakodzera kugoverwa kudzimba nemabhizinesi.
Maindasitiri Zvishandiso: Iwo anoshandiswa mumaindasitiri zvigadziriso kuti ape anodiwa voltage mazinga emuchina akasiyana nemidziyo.
Mhedziso
Muchidimbu, ma transformer azvino uye magetsi emagetsi anoshanda akasiyana asi anopindirana mabasa mumagetsi masisitimu. Vashanduri vemazuva ano vanonyanya kushandiswa kuyera uye kutarisa mazinga akakwirira emazuva ano zvakachengeteka uye zvakarurama, asi magetsi emagetsi anokosha pakufambisa uye kugovera simba remagetsi. Kunzwisisa mashandiro uye mashandisirwo eaya ma transformer kwakakosha kune chero munhu ane chekuita mumunda weinjiniya yemagetsi.
