Osintha ma tap ndi zida zomwe zimatha kuwonjezera kapena kutsitsa ma voliyumu achiwiri posintha chiwongolero cha mafunde a pulayimale kapena yachiwiri. Chosinthira chapampopi nthawi zambiri chimayikidwa pagawo lamphamvu lamagetsi lamagetsi opindika awiri, chifukwa cha kutsika kwamagetsi m'derali. Osinthawo amaperekedwanso pa ma windings apamwamba a thiransifoma yamagetsi ngati pali mphamvu yokwanira yamagetsi. Kusintha kwamagetsi kumakhudzidwa mukasintha kuchuluka kwa matembenuzidwe a transformer operekedwa ndi matepi.
Pali mitundu iwiri ya Tap Changers:
1. Pa-Katundu Tap Changer
Chinthu chake chachikulu ndi chakuti panthawi yogwira ntchito, dera lalikulu la kusintha sikuyenera kutsegulidwa. Izi zikutanthauza kuti palibe gawo la chosinthira liyenera kupeza dera lalifupi. Chifukwa chakukula komanso kulumikizidwa kwamagetsi, zimakhala zofunikira kusintha matepi osinthira kangapo tsiku lililonse kuti akwaniritse ma voliyumu ofunikira malinga ndi kuchuluka kwa katundu.
Kufunika kopereka mosalekeza sikukulolani kuti mutsegule chosinthira kuchokera pakompyuta kuti musinthe ma tap otsitsa. Chifukwa chake, osintha ma tap onyamula amawakonda kwambiri pamagetsi ambiri.
Zinthu ziwiri ziyenera kukwaniritsidwa pogogoda:
· Dongosolo lonyamula katundu liyenera kukhala losasunthika kuti zisawonongeke komanso kupewa kuwonongeka kwa kulumikizana
·Mukamakonza mpopi, palibe mbali iliyonse ya ma windings yomwe iyenera kukhala yofupikitsa
Pachithunzi pamwambapa, S ndiye chosinthira chosinthira, ndipo 1, 2 ndi 3 ndi masiwichi osankha. Kusintha kwapampopi kumagwiritsa ntchito riyakitala yokhomedwa pakati R monga momwe zikuwonekera pachithunzichi. Transformer imagwira ntchito pomwe masiwichi 1 ndi S atsekedwa.
Kuti musinthe ku tap 2, switch S iyenera kutsegulidwa ndikusintha 2 iyenera kutsekedwa. Kuti mumalize kusintha kwapampopi, sinthani 1 imagwira ntchito ndipo switch S imatsekedwa. Kumbukirani kuti diverter switch imagwira ntchito pakudzaza ndipo palibe kuyenderera kwaposachedwa pamasinthidwe osankha panthawi yosintha kampopi. Mukadina kusintha, theka lokha la zomwe zimalepheretsa zomwe zilipo zimalumikizidwa kuzungulira.
2.Off-Load/No-load Tap Changer
Muyenera kukhazikitsa chosinthira chotsitsa pa thiransifoma ngati kusintha kofunikira kwamagetsi sikuchitika pafupipafupi. Ma tapi amatha kusinthidwa mutasiyaniratu chosinthira kudera. Kusintha kwamtunduwu nthawi zambiri kumayikidwa pa transformer yogawa.
Kusintha kwapampopi kumatha kuchitika pomwe thiransifoma ili mu Off-Load kapena No-Load. Mu chowotcha chowuma chowuma, chozizira chozizira chimachitika makamaka ndi mpweya wachilengedwe. Mosiyana ndi kusintha kwapampopi wapa-load komwe kuzimitsa kwa arc kumakhala kochepa ndi mafuta pomwe thiransifoma ili yodzaza, kugogoda ndi chosinthira chapampopi chotsitsa kumangochitika pomwe thiransifoma ili mu OFF-Switch.
Amagwiritsidwa ntchito nthawi zambiri pomwe kutembenuka sikufunikira kusinthidwa kwambiri, ndipo kuchotsera mphamvu kumaloledwa mumagetsi otsika komanso otsika ma voltages. Mwa zina, kusintha kwapampopi kumatha kuchitidwa ndi rotary kapena slider switch. Zitha kuwoneka makamaka m'mapulojekiti amagetsi a dzuwa.
Zosintha zama tap-off-load zimagwiritsidwanso ntchito pamagetsi apamwamba kwambiri. Dongosolo la thiransifoma yotere limaphatikizapo kusintha kwapampopi kopanda katundu pamayendedwe oyambira. Kusintha uku kumathandizira kutengera kusiyanasiyana mkati mwa bandi yopapatiza mozungulira mavoti mwadzina. M'makina otere, kusintha kwapampopi nthawi zambiri kumachitika kamodzi kokha, panthawi yoyika. Komabe, itha kusinthidwanso panthawi yomwe yazimitsidwa kuti ithetse kusintha kulikonse kwanthawi yayitali pamawonekedwe amagetsi amagetsi.
Ndikofunikira kuti musankhe mtundu woyenera wa chosinthira chotengera kutengera zomwe mukufuna.
