"SISTEMA DI CONDIVISI ONE ENERGETICA DA DIVERSE FONTI IN CUI LA RETE PUBBLICA HA FUNZIONE PASSIVA 0 DI AUSILIO 0 DI EMERGENZA" _ SHARED POWER FROM DIFFERENT SOURCES SYSTEM IN WHICH PUBLIC MAINS HAS PASSIVE, HELP OR EMERGENCY FUNCTION- "SHARED POWER FROM DIFFERENT SOURCES SYSTEM IN WHICH PUBLIC MAINS HAS PASSIVE, HELP OR EMERGENCY FUNCTION-

TESTO DELLA DESCRIZIONE TEXT OF THE DESCRIPTION

Il presente trovato realizza 1' alimentazione autonoma di un carico elettrico, a titolo esemplificativo ma non limitativo, di una abitazione, sfruttando la fonte di energia rinnovabile o alternativa o di emergenza prima di ricorrere al prelievo della quota mancante dalla rete pubblica. The present invention provides the autonomous power supply of an electric load, by way of example but not of limitation, of a house, exploiting the renewable or alternative or emergency energy source before resorting to drawing the missing portion from the public network.

Il trovato realizza una condivisione in una forma mista di utilizzo di energia, privilegiando la fonte rinnovabile o alternativa o di emergenza. The invention realizes a sharing in a mixed form of energy use, favoring the renewable or alternative or emergency source.

Questo trovato non necessita di collegarsi in parallelo alla rete pubblica, non restituisce energia in rete che conserva la sua funzione di erogatore di energia. This invention does not need to be connected in parallel to the public network, it does not return energy to the network which retains its function as an energy supplier.

Il trovato può essere installato senza interferire con le prerogative della rete pubblica e realizzare un risparmio energetico . The invention can be installed without interfering with the prerogatives of the public network and achieve energy savings.

Viene quindi condivisa energia in modo semplice e dosata a favore di quella rinnovabile quando e nella quantità in cui è disponibile . Energy is therefore shared in a simple and measured way in favor of renewable energy when and in the quantity in which it is available.

Il trovato permette anche una semplice aggiunta di accumulatori di energia utilizzando, in forma esemplificativa ma non limitativa, batterie o condensatori. The invention also allows a simple addition of energy accumulators by using, in exemplary but not limiting form, batteries or capacitors.

Il trovato può essere dotato di un sistema, a scopo esemplificativo ma non limitativo, di commutazione elettrica che permetta il ritorno alla situazione di impianto di tipo standard o classico in uso. The invention can be equipped with an electrical switching system, by way of example but not of limitation, which allows the return to the situation of a standard or classic type of plant in use.

Ulteriori caratteristiche e vantaggi del trovato risulteranno maggiormente dalla descrizione di forma di realizzazione preferita, ma non esclusiva, del dispositivo secondo il presente trovato, illustrate a titolo indicativo e non esclusivo nel disegno di Figura 1. Further characteristics and advantages of the invention will become clearer from the description of the preferred but not exclusive embodiment of the device according to the present invention, illustrated by way of example and not exclusively in the drawing of Figure 1.

La Figura 1 illustra uno schema circuitale di una forma di realizzazione del dispositivo secondo il presente trovato. Figure 1 illustrates a circuit diagram of an embodiment of the device according to the present invention.

Al riferimento a) la fonte di energia rinnovabile (in questo caso un impianto fotovoltaico) genera una tensione e una corrente continua. At reference a) the renewable energy source (in this case a photovoltaic system) generates a voltage and a direct current.

Al riferimento d) un diodo, che impedisce il ritorno di corrente verso la a), permette alla rete pubblica, tramite il ponte e), di integrare, in caso di necessità, la quota mancante di energia. In alternativa al ponte e) è utilizzabile il diodo di) e/o il dispositivo fi). At reference d) a diode, which prevents the current from flowing back towards a), allows the public network, via bridge e), to integrate, in case of need, the missing portion of energy. As an alternative to bridge e) the diode di) and / or the device fi) can be used.

Può essere utilizzata una fonte di accumulo di energia nella forma di batterie o accumulatori o condensatori come al riferimento b) . An energy storage source in the form of batteries or accumulators or capacitors as in reference b) can be used.

Al riferimento f) un trasformatore ad alto rendimento (toroidale) isola galvanicamente e adatta la tensione di rete al minimo funzionale dell' inveter c). La medesima funzione può essere realizzata utilizzando il diodo di) e/o il dispositivo fi) . At reference f) a high-performance (toroidal) transformer galvanically isolates and adapts the mains voltage to the minimum functional value of the inverter c). The same function can be realized by using the diode di) and / or the device fi).

In breve, la fonte rinnovabile o alternativa o di emergenza fornisce tensione all' inverter c) che la trasforma in tensione alternata e alimenta il carico i). In short, the renewable or alternative or emergency source supplies voltage to the inverter c) which transforms it into alternating voltage and supplies the load i).

La tensione all' ingresso dell' inveter non potrà scendere in prossimità del suo minimo funzionale perché questo sarà impedito dalla tensione raddrizzata e di valore leggermente superiore a questo minimo funzionale proveniente dalla rete pubblica tramite g) , f) , e) oppure g) , di) , fi) o sistema con funzioni equivalenti. The voltage at the inverter input will not be able to drop near its functional minimum because this will be prevented by the rectified voltage and of a value slightly higher than this functional minimum coming from the public network through g), f), e) or g), di), fi) or system with equivalent functions.

In questo modo si ottiene un sistema bilanciato senza dover variare 1' assetto di utente della rete pubblica. In this way a balanced system is obtained without having to vary the user set-up of the public network.

Al riferimento h) la presenza di una commutazione di emergenza salvaguarda da possibili disservizi del trovato illustrato riportando 1' assetto elettrico alla forma originale (la commutazione h) può anche essere parte di c). At reference h) the presence of an emergency switching protects against possible disruptions of the illustrated invention by restoring the electrical set-up to its original form (switching h) can also be part of c).
