Uburinzi bw'ibisasu bya Wolong Nanyang: Ni iki ukwiye kwitaho mugihe ushyiramo kandi ukoresha transformers zigezweho (CT)?

Ni ngombwa kuzirikana ibintu byinshi by'ingenzi mu gushyiraho no gukoresha transformers zigezweho (CTs) kugira ngo habeho imikorere myiza n'umutekano. Aho transformer igezweho igomba gutoranywa hashingiwe ku bipimo byihariye n'ibisabwa mu kurinda. Ni ngombwa rero ko sisitemu y'amashanyarazi isuzuma neza mbere yo kuyishyiraho kugira ngo hamenyekane ahantu heza cyane kuri CT. Gushyira neza imiterere bishobora kongera cyane uburyo ibipimo bipimwe neza no kwizera uburyo bwo kuyirinda.

Uburyo bwo gufunga insinga bukoreshwa kuri transformateur y'amashanyarazi nabwo bufite akamaro kanini mu bijyanye n'imikorere yayo. Hariho uburyo butandukanye bwo gufunga insinga, harimo n'uburyo bwo gukora insinga imwe,Inyenyeri y'icyiciro cya gatatu (ihuza rya Y), naDelta y'ibice bitatu (Δ connection)Buri buryo bufite ibyiza byabwo kandi bukwiriye gukoreshwa mu buryo butandukanye. Urugero, insinga z'inyenyeri eshatu zikoreshwa mu buryo busanzwe zikwiriye imitwaro iringaniye, mu gihe insinga za delta zifitiye akamaro sisitemu zidakora neza. Ni ngombwa cyane guhitamo uburyo bukwiye bwo gukoresha insinga kugira ngo hirindwe ko insinga zifunguye, zishobora gutera imiterere idahwitse no kwangirika kwa transformateur.

Byongeye kandi, iyo ushyizeho transformateur y'amashanyarazi yaMoteri ya AC, ni ngombwa gusuzuma umutwaro uri ku ruhande rwa kabiri. Gushyiramo CT cyane bishobora gutuma habaho ubwinshi bw'umutwaro, bishobora gutuma ibipimo bihindagurika. Ni ngombwa rero kugenzura ko umutwaro uhujwe utarenga umutwaro wagenwe na transformer.

Byongeye kandi, ni ngombwa kugenzura ko ishyirwaho ryujuje amategeko n'amabwiriza yose y'amashanyarazi, kandi ko imiyoboro yose ihamye. Gufata no gusuzuma transformateur zigezweho nabyo birasabwa kugira ngo bikomeze kuba byiza kandi byizerwa.
