Cos'è il relè di commutazione?

Un interruttore relè è un dispositivo di commutazione azionato elettricamente che apre e chiude i circuiti dopo aver ricevuto un segnale elettrico dall'esterno. Ci sono molti tipi di interruttori relè, e sono disponibili in diverse forme, dimensioni e disegni in vari stili.


Come funziona un relè di commutazione


I "relè" incorporati nei prodotti elettrici funzionano in modo simile; ricevono un segnale elettrico e lo inviano ad altre apparecchiature. Ad esempio, quando vogliamo accendere il televisore con un telecomando, invia un segnale elettrico al "relè" all'interno del televisore e accende l'alimentazione
principale. Può essere utilizzato per controllare riscaldatori, motori, carichi di corrente, lampade o circuiti AC in modo che possano attirare tensioni
elettriche, correnti e potenza molto più elevate. Inoltre, il relè può essere utilizzato per valvole a gas, illuminazione, fari, e sistemi di allarme. In realtà, ci sono alcuni dispositivi elettronici che non possono
funzionare efficacemente senza l'uso di relè.

Perché un relè si surriscalda?


Ci possono essere molte ragioni per cui un relè si surriscaldi. Tuttavia, burn out non significa che i relè si surriscaldino con il fuoco, in quanto per i componenti relè viene utilizzato materiale resistente alla fiamma. Ecco alcuni motivi comuni per
cui i relè si surriscaldano, o le bobine mostrano segni di calore anormale:

•Superamento del valore massimo corrente
•Se la tensione di contatto supera il valore massimo
•Vibrazione di contatto
•Cortocircuito
•Per contatti corrosi o polvere di carbonio

Chi può implementare un relè di commutazione?


Il relè di commutazione è ampiamente utilizzato in diversi contesti grazie alla sua versatilità. Ecco alcuni dei luoghi e delle applicazioni in cui viene utilizzato:

Automazione industriale: nei sistemi di automazione industriale, gli interruttori relè vengono utilizzati per controllare motori, valvole, pompe e altri dispositivi elettrici. Ad esempio, possono avviare o arrestare una catena di produzione o attivare un sistema di allarme.
Elettronica: viene utilizzato anche nei circuiti elettronici per cambiare il segnale o l'alimentazione.
•Energia: nei quadri elettrici e nei pannelli di controllo, i relè sono utilizzati per la distribuzione di energia. Possono proteggere i circuiti da sovraccarichi o cortocircuiti, garantendo il funzionamento sicuro dei sistemi.
•Domotica: nei sistemi di domotica, viene utilizzato per controllare luci, tende, serrature e altri dispositivi domestici. Consentono l'automazione e la gestione intelligente dell'ambiente.
•Sistemi di sicurezza: i relè sono utilizzati anche nei sistemi di sicurezza, come i rilevatori di gas, gli allarmi antincendio e i sistemi di controllo degli accessi. Possono attivare avvisi o interrompere l'alimentazione in caso di emergenza.
