Mfundo ndi ntchito ya high-voltage soft starter

Mawu Oyamba: Choyambira chofewa chapamwamba kwambiri, chomwe chimatchedwanso sing'anga ndi high-voltage solid-state soft starter (Medium, High-voltage solid-state soft starter), ndi mtundu watsopano wa zoyambira zanzeru zamagalimoto, zomwe zimakhala ndi switch yodzipatula, fusesi. , control transformer, control module, thyristor Module, high-voltage vacuum bypass contactor, control module, thyristor module, high-voltage vacuum bypass contactor, thyristor protection component, optical fiber trigger component, kupeza chizindikiro ndi chigawo cha chitetezo, kulamulira dongosolo ndi chigawo chowonetsera. .Choyambira chofewa champhamvu kwambiri ndi chida chowongolera ma motor terminal chomwe chimaphatikiza kuyambira, kuwonetsa, chitetezo, ndi kupeza deta, ndipo imatha kuzindikira ntchito zowongolera zovuta.

Choyambira chofewa champhamvu kwambiri chimawongolera ma voliyumu olowera poyang'anira ma conduction a thyristor kuti asinthe mtengo wamagetsi a stator terminal ya mota, ndiye kuti, imatha kuwongolera ma torque oyambira ndikuyambira ma motor, kuti Kuyamba kofewa kwagalimoto kumatha kuzindikirika Tengani ulamuliro.Panthawi imodzimodziyo, imatha kufulumizitsa bwino malinga ndi magawo oyambira, potero kuchepetsa mphamvu yamagetsi pa gridi, galimoto ndi zipangizo.Pamene galimoto kufika liwiro oveteredwa, ndi kulambalala contactor basi chikugwirizana.Galimoto imatha kuyang'aniridwa pambuyo poyambira, ndipo zotetezedwa zosiyanasiyana zimaperekedwa.

Chipangizo choyambira chofewa champhamvu kwambiri chimatha kuyambitsa makinawo kwanuko, kapena kugwiritsa ntchito cholumikizira chowuma chakunja poyambira kutali.Nthawi yomweyo, PLC ndi kulumikizana (mawonekedwe a 485, Modbus) zitha kugwiritsidwanso ntchito poyambira kuyimitsa.Mukayamba chipangizo choyambira chofewa champhamvu kwambiri, mutha kusankha njira ziwiri zoyambira zofewa (zoyambira zofewa, zoyambira zofewa, zoyambira zofewa, zoyambira zofewa nthawi zonse, kuyambika kwamagetsi apawiri, ndi zina zambiri) kapena kuyambitsa mwachindunji kukumana ndi zosowa zosiyanasiyana za tsamba lofunsira.

Njira yowongolera mwanzeru ya choyambira chofewa chapamwamba kwambiri imatha kukhazikitsa magawo monga kuyambira torque, kuyambira pano, nthawi yoyambira, ndi nthawi yotseka, komanso imatha kuwongoleredwa ndikulumikizana ndi ma microcomputer ndi ma PLC.Poyerekeza ndi choyambira chachikhalidwe (choyambira chamadzimadzi champhamvu kwambiri), chimakhala ndi zabwino zake zazing'ono, kukhudzika kwakukulu, kusalumikizana, kugwiritsa ntchito mphamvu zochepa, kudalirika kwakukulu, komanso kusakonza (thyristor ndi chipangizo chamagetsi chosalumikizana) Kugwira ntchito mosalekeza kwa zaka zingapo popanda kutsika kwanthawi yokonza), kukhazikitsa kosavuta (kutha kukhazikitsidwa pambuyo polumikiza chingwe chamagetsi ndi chingwe chamoto), kulemera kwamphamvu, ntchito zonse, magwiridwe antchito, magwiridwe antchito mwachilengedwe, etc.

Choyambira chofewa champhamvu kwambiri chimatha kuwonjezera mphamvu zamagetsi, kupewa kuyambika, kupereka chitetezo pamakina opangira magetsi ndi ma mota ndi zida zina, ndikutalikitsa moyo wautumiki wa zida zamagetsi ndi mabwalo.
