Abstract
Circuito eléctrico de protección de sistemas
fotovoltaicos.
La presente invención tiene como objeto
proporcionar una estructura para la protección eléctrica de
instalaciones fotovoltaicas, en el caso en que al conectar el
generador fotovoltaico (G_{1}-G_{p}), se conecte
con la polaridad invertida, para lo que cuenta con una célula de
protección que comprende dos puntos de conexión (1, 2) en los que
se conecta el generador fotovoltaico
(G_{1}-G_{p}), al menos un dispositivo (D) de
reducción de la tensión del generador fotovoltaico
(G_{1}-G_{p}) en caso de inversión de polaridad,
que está conectado en paralelo entre los dos puntos de conexión
anteriormente citados, y al menos un elemento de apertura y/o
protección (M) del generador fotovoltaico
(G_{1}-G_{p}) conectado en serie con los
elementos anteriores; minimizando las solicitaciones sobre estos
elementos de apertura y/o protección.
