This work is a feasibility study for the development of an innovative Medium Voltage panel for secondary distribution. The innovations which are introduced are: 1. Using a vacuum circuit breaker to protect distribution transformers. 2. Integrating current and voltage sensors inside the bushings of the multifunction apparatus which includes the mentioned vacuum circuit breaker. 3. Using shielded insulated deadbreak connectors for the outgoing cables of the multifunction apparatus. Benefits of the proposed design include effectiveness of transformer protection, short breaking time in case of faults, compactness, ease of installation and robustness towards environmental conditions and pollution.
Questo lavoro di tesi riguarda lo sviluppo di un modello innovativo di pannello per quadri in media tensione di distribuzione secondaria. Le innovazioni introdotte sono: 1. L’utilizzo di un interruttore in vuoto come dispositivo di protezione per trasformatori MT/BT. 2. L’integrazione di sensori di misura di corrente e tensione all’interno degli isolatori passanti dell’apparato multifunzione contenente il suddetto interruttore in vuoto. 3. L’utilizzo di terminali isolati e schermati per l’attacco dei cavi di media tensione all’apparato multifunzione. Questa configurazione garantisce una protezione trasformatore compatta ed efficace, capace di intervenire in tempi rapidi, caratterizzata da un’installazione semplice e resistente a condizioni ambientali avverse e inquinamento.
