Acesta actioneaza simultan trei motoare asincrone. Folosim reteaua industriala trifazata de 0.4kV\/50Hz. Echipamentul este destinat actionarilor electrice cu turatie variabila. Se utilizeaza doua sau mai multe motoare asincrone. Acestea au rotorul in scurtcircuit. Produsele se aplica excelent in industrie. De asemenea, sunt perfecte in tractiunea electrica. Principalele caracteristici electrice: Tensiunea de alimentare: 3x400Vac; Convertizoare de frecventa: 2x55KW; Frecventa de iesire: 0\u00f7400 Hz; Sincronizare in frecventa sau in cuplu. Schema bloc a dispozitivului electronic Schema proiectata prin aceasta tema de cercetare este complexa. Ea contine urmatoarele blocuri functionale de baza: Circuitul de cuplare la reteaua industriala (rol de conectare si protectie); Blocul redresor cu diode si filtrul pentru circuitul intermediar; Invertorul de recuperare in retea a energiei individuale de franare; Convertizoarele de frecventa realizate in tehnologie avansata IGBT; Unitatea de comanda cu DSP care controleaza fiecare bloc functional. Invertorul inlocuieste clasicele choppere si rezistente de franare. Convertizoarele de frecventa vor functiona in regim master-slave. Ele folosesc metoda moderna de reglare vectoriala. Domenii de utilizare si avantaje majore Domenii industriale de aplicabilitate: Industria cimentului (mori si benzi transportoare); Industria de fabricare a hartiei (tamburi); Industria extractiva (excavatoare si abzetere); Tractiunea electrica urbana (tramvai, troleibuz, metrou); Tractiune feroviara (locomotive, rame electrice); Alte aplicatii multi-motor complexe. Avantajele utilizarii dispozitivului: Incarcarea optima a fiecarui motor electric; Protectia individuala si sigura a fiecarui motor; Utilizarea unui circuit unic de curent continuu; Cresterea semnificativa a eficientei energetice; Pret de cost redus fata de echipamentele clasice; Realizare modulara pentru un service mult mai usor.
