Ziva Overhead Lines uye Electrical Towers

Mitsetse yepamusoro inotsigirwa nezvikamu zveshongwe dzekutumira.

Mapiloni emagetsi anoshandiswa kune akakwira tension tambo.

Uye mapango emapuranga kana kongiri anowanzo shandiswa kune yakaderera tension mitsetse.

Izvi zvinodaro nekuti mitsetse yepamusoro yekumanikidzana (high tension line) inofanira kuiswa panzvimbo yakakwirira, sezvo vachida kuchengetedzwa kwakanyanya.

Mapiloni emagetsi chete anokwanisa kutakura mitsetse yemakumi ematani.

Zvaunoona munzira pamusha pemasabhubhu kazhinji shongwe dzekutumira.

Kana dziri mhando dzeshongwe, kune katsi-musoro shongwe, waini-girazi shongwe, shongwe dzakaita semagedhi, shongwe dzakaita seV, etc.

Voltage pamitsetse yekufambisa pamusoro

Rated voltage inoreva voltage pakati pezvipi zviviri zvezvikamu zvitatu zveABC.

Muyero wemagetsi wepamba we 220 volts ndiyo voltage iri pakati peimwe yezvikamu zvitatu kusvika pasi.

Muchokwadi, mutsetse unoendesa magetsi kumba ndiwo 380 volts.

Uye zvikamu zvitatu zvinoparadzaniswa vasati vapinda mumba.

Semuyenzaniso, chimwe nechimwe chezvikamu zvitatu zveABC chakabatana kune chimwe nechimwe chezvikamu muchivakwa.

Musoro wepasi mitsetse

Mitsetse yekutumira yakakamurwa kuita yakananga ikozvino uye inochinjika ikozvino (DC uye AC).

An AC inotenderera inoumbwa nezvikamu A, B uye C.

Pamusoro peiyo transmission tower ndiyo mutsara wemheni, inonziwo overhead ground wire.

Mitsetse iri munzvimbo dzine madutu akawanda kana high voltage ine mitsara miviri yemheni.

Mitsetse ine dutu shoma kana kuti low voltage inogona kushandisa tambo imwe chete yemheni.

Mitsara yemheni yakabatana nematanda kuti itungamire mheni pasi.

Mitsetse yekutakura pamusoro

Pazasi pemitsara yemheni pane tambo dzekutumira.

Nhamba yewaya dzese dzakapetwa ka 3. Mutsara mumwe chete wedunhu une 3 waya, mutsara wedunhu-mbiri une 6 waya, uye mutsetse wechina wedunhu une 12 waya.

Mudunhu rega rega mune waya nhatu kune chimwe nechimwe chezvikamu zvitatu A, B uye C.

Chikonzero nei paine akati wandei matunhu mushongwe zvinonyanya kukonzerwa nekufunga kwekutapurirana simba uye tsoka. This is why the concepts of “line length” and “circuit length” have also been developed.

Yemitsetse miviri-yedunhu, kureba kwedunhu kaviri kureba kwemutsara zvichingodaro.

Panyaya yemhando dzakasiyana dzemagetsi, iyo voltage ye conductor yepamusoro yakakwirira kudarika iyo yepasi conductor.

Izvi zvinodaro nekuti iyo yakakwira voltage, chikuru chinodiwa chekuchengetedza chinhambwe kusvika pasi.

Tambo dzemheni dzakanyatsosiyaniswa kubva kune tambo dzekutumira.

Iyo yekutanga yakananga pamusoro peshongwe, nepo iyo yekupedzisira inofanirwa kumiswa kubva pashongwe nema insulators.

Kana pasina insulators, conductor inopfupikiswa yakananga kushongwe.

Iyo insulator chinhu chinowanikwa kune waya dziri pamusoro (waya dzepamusoro) inoshandiswa kutsigira uye kuchengetedza conductor.

Inogona kuve nechokwadi chinhambwe chakakodzera uye kuvharirwa pakati pemakondakita kana pakati pemakondakita uye pasi.

MaInsulators anofanirwa kunge aine simba rekudzivirira remagetsi rakakwana uye kudzivirira hunyoro.

Tinovimba kuti chinyorwa ichi chichakubatsira iwe kuti unzwisise mutsara wepamusoro uye shongwe yemagetsi nemazvo.

Isu tinopa mhando yepamusoro uye yakaderera mutengo wezvakasiyana mitsara yepamusoro uye zvishongedzo zvavo.

Ndapota taura nesu kana uchivada.
