Ndezvipi rwokuyera transformers

Instrument transformers zvinoshandiswa RPA ongororo mumatunhu kuti uno uye voltage tsika. Izvi zvinokosha kuti ataure kudzivirira nguva aigona kushanda maererano setpoint, magetsi injiniya panguva nokutumwa. Kazhinji, matunhu zvinoshandiswa RPA kuyera kuitika uye voltage transformers. Ngatikurukurei chimwe nechimwe mhando yoga.

Voltage transformers zvinoshandiswa kudzivirira dzidziso pamusoro kutsigirwa mhando iyi, iyo iri kuitwa panyaya Countdown danho kusuduruka pamakona uye akarongeka kudzivirira nyika mhosva achibatsirwa Coils chokuita nevanhu rakavhurika Triangle zano.

Kuyera voltage transformers yaitwa wandei Kern: mumwe kwakabatana ne "nyeredzi" muenzaniso, wechipiri - a "wakaputsika Delta". Nhasi, kugadzira miti kubereka transformers vane punchi wechitatu, iro rinoshandiswa kuti ndizvidavirire.

For RU-35-110 KV akagadza matatu -phase transformer voltage. Nokuti mumwe boka nomumwe yeimwe vakatasva michina. For RU 6-10 KV anowanzodanwa kushandiswa-danho matatu TN mune rimwe pasuru.

Kuyera ano transformers zvinoshandiswa yose Uzbekistan uye yakasimbiswa mune phased nenzira. transformers izvi zviri akagadzirwa monolithic matai, unova muchitokisi chikuru. Bus wakaiswa yechipiri ichitenderera rwendo, pangava dzakawanda, mumwe ichitenderera (hereinafter chinoumba) rakagadzirirwa boka chaicho zvakarurama uye yakananga simba.

That cores vari goho nokuda redunhu kudzivirirwa nekuyera uye metering. Zvakakosha kuti magetsi transformers haana kumbova raskorochennyh paro, zvimwe ari coils zvichatsva, uye mudonzvo mungozi yokuva akarova electrocution.

Kana kugadzwa rwokuyera ano transformers anofanira kuisa maererano dhayagiramu chiyamuro-goho voltage (L1 - chiyamuro A2 - goho). On ichi zvinoenderana kutungamirirwa vectors ari kuitika nerimwe Pasika. Maererano chaiyo, pakati vectors ose dzenzvimbo, izvo windings chokuita pamusoro "nyeredzi" dzinofanira kuva 120 inegumi. Kana kuti zvimwe chikonzero ari vectors vanosarudzirwa zvakasiyana, unofanira kuchinja kubatana makirisito TT, swapping pakutanga kusvikira pakupedzisira.

Current transformers inoshandiswa kudzivirira nematunhu pfupi uye kuti kuronga kuti differential dziviriro. Kuyera ano transformers - chinokosha chokufunga magetsi ano, ndiko Switch, makubhiti kuitika ukoshi hwayo mirayiridzo.

The zvemagetsi transformer rinoshandiswa zero kutevedzana. chaikosha ichi akakodzera kuti RU-0,4-6-10 KV, sezvo basa iri transformer (mumba doughnut) kudzivirira redunhu mukuru voltage pasi mhosva. Sero ake chikuru - pachayo ine feeder, riri vakapfuura Bagel. Sezvo yechipiri wakasuduruka ukoshi izvo dzinosiyana maererano nokuchinja remagineti yacho feeder.

Nokudaro, transformers kuti uno uye voltage chipimo - ndiyo hwaro wokudzivirira. Kuburikidza navo microprocessors ano vanogona vakazvimiririra ngaaverenge simba, kuti kurwisa ari cheni chikamu, pamakona pakati ano uye voltage. The Zvakawanikwa hazvidi kuti kuongororwa, sezvo midziyo ano rinoitwa pamwe noungwaru zvigadzirwa.

Nhasi, zvikuru nevakawanda mudziyo, inova zvakakwana mhinduro uye zvinosanganisira dunhu namapoporodzi, disconnectors, uyewo pakuvara kuitika uye voltage transformers - zviri nyore uye zvikuru zvinobatsira.
