Kodi ntchito ya SWITCH YA VOLTAGE LOAD SWITCH ndi yotani?

Chosinthira champhamvu chamagetsi ndi chipangizo chamagetsi champhamvu chophatikizana, chomwe chimakhala ndi chosinthira chodzipatula, fuse, chosinthira kutentha, chotulutsa shunt ndi chipangizo chozimitsira arc.

Chosinthira champhamvu chamagetsi chili ndi chipangizo chosavuta chozimitsira magetsi, chomwe chingagwiritsidwe ntchito kokha kupanga ndikuswa mphamvu yanthawi zonse yamagetsi, ndipo sichingagwiritsidwe ntchito kuswa mphamvu yafupipafupi yamagetsi. Chifukwa chake, chosinthira champhamvu chamagetsi nthawi zambiri chimagwirizanitsidwa ndi fuse yamphamvu yamagetsi komanso kutulutsa kutentha, ndipo fuse imagwiritsidwa ntchito kudula mphamvu yafupipafupi yamagetsi panthawi yamagetsi yochepa. Ngati pali kuchuluka kwamagetsi, kutulutsa kutentha kumagwira ntchito yokha kuti kugwetse chosinthira katundu. Popeza pali kusiyana koonekeratu pamene chosinthira katundu chatsekedwa, chilinso ndi ntchito yolekanitsa magetsi kuti zitsimikizire kuti akusamalidwa bwino.

Chosinthira chamagetsi champhamvu kwambiri ndi zida zamagetsi zophatikizika ndizoyenera kugwiritsa ntchito makina amphamvu a AC 10 kV, 50 Hz, kapena kugwiritsidwa ntchito limodzi ndi zida zonse zogawa magetsi, makabati osinthira maukonde a mphete, malo osinthira magetsi ophatikizika, ndi zina zotero, ndipo zimagwiritsidwa ntchito kwambiri pa ntchito zomanga ndi kukonzanso maukonde a m'deralo, mabizinesi amafakitale ndi migodi, nyumba zazitali komanso malo ogwirira ntchito anthu onse, ndi zina zotero, chingagwiritsidwe ntchito ngati choperekera magetsi cha maukonde a mphete kapena malo olumikizira magetsi, ndipo chimagwira ntchito ngati chogawa magetsi, kuwongolera ndi kuteteza. Chili ndi ubwino wokhala ndi mphamvu yayikulu yosweka, chitetezo ndi kudalirika, moyo wautali wamagetsi, kugwira ntchito pafupipafupi, kapangidwe kakang'ono, kukula kochepa, kulemera kopepuka, komanso osakonza. Ndi mphamvu yosweka, mphamvu yowonjezera. Imatha kuswa mphamvu yamagetsi yafupikitsa ndikuletsa kuti zida zisagwire ntchito. Chosinthiracho chili ndi kusweka koonekeratu. Chili ndi njira yamagetsi yamagetsi ya chosinthira choyambira chomwe chimatha kutsekedwa, chomwe chingawongoleredwe patali.

Chosinthira mphamvu (QL) ndi chosinthira mphamvu chomwe chimapangidwa kuti chipange ndikuswa mafunde amagetsi. Chosinthira mphamvu chamagetsi champhamvu chili ndi chipangizo chozimitsira mphamvu cha arc chosavuta komanso malo odziwikiratu olumikizira magetsi, chomwe chimatha kuyatsa ndikuzimitsa mphamvu yamagetsi ndikuwonjezera mphamvu yamagetsi, ndipo chimagwira ntchito ngati chosinthira chodzipatula, koma sichingathe kulumikiza mphamvu yamagetsi yafupikitsa. Nthawi zambiri, fakitale yosinthira mphamvu imagwiritsidwa ntchito limodzi ndi ma fuse kuti idule mphamvu yamagetsi pogwiritsa ntchito ma fuse, omwe angagwiritsidwe ntchito kwambiri pakukonzanso magetsi m'mizinda ndi m'midzi. Amagwiritsidwa ntchito makamaka pa gridi yamagetsi ya 6~10kV.

Malinga ndi chipangizo chozimitsira mpweya cha arc, chosinthira champhamvu kwambiri chimagawidwa makamaka m'magulu awiri: mtundu wa mpweya wopangidwa ndi mpweya, mtundu wa mpweya wopanikizika, mtundu wa vacuum ndi mtundu wa SF6. Malinga ndi malo oyika, chimagawidwa m'magulu awiri: mtundu wamkati ndi mtundu wakunja.

Chosinthira cha load switch ndi chosavuta kupanga, chaching'ono komanso chotsika mtengo, ndipo chimagwiritsidwa ntchito nthawi zina zomwe sizifuna mafuta, zosakonzedwa, komanso zogwiritsidwa ntchito pafupipafupi. Kuphatikiza ndi ma fuse, chingagwiritsidwe ntchito ngati chosinthira chamagetsi kwa ogwiritsa ntchito omwe ali ndi mphamvu zochepa kapena zosafunikira kuti alowe m'malo mwa ma circuit breakers. Chosinthira cha load switch chimasankhidwa malinga ndi voltage yoyesedwa ndi current yoyesedwa, ndipo chimawunikidwa kuti chiwone ngati chili chokhazikika komanso kutentha. Chikakhala ndi fuse, mphamvu yosweka ya fuse iyenera kutsimikiziridwa, ndipo kukhazikika kwake kwa mphamvu ndi kutentha sikungatsimikizidwe.
