Comprendre <\/span>Comment raccorder des relais statiques<\/span><\/a><\/span> est important, mais il est tout aussi essentiel d'en comprendre les applications.<\/span><\/p>

En comprenant leurs applications, nous pouvons savoir dans quelles situations et comment les utiliser au mieux.<\/span><\/p>

Dans cet article de blog, nous allons \u00e9num\u00e9rer 10 domaines d'application pour <\/span>relais \u00e0 semi-conducteurs<\/span><\/a><\/span>, notamment : la r\u00e9gulation de la temp\u00e9rature, les \u00e9quipements alimentaires et d'emballage, la domotique, le d\u00e9marrage et l'arr\u00eat des moteurs, et bien d'autres encore.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

1. Syst\u00e8me de r\u00e9gulation de la temp\u00e9rature pour le chauffage industriel<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Contrairement \u00e0 la commande des compresseurs dans les syst\u00e8mes de r\u00e9frig\u00e9ration (rappelons que les d\u00e9marrages et arr\u00eats fr\u00e9quents des compresseurs r\u00e9duisent consid\u00e9rablement leur dur\u00e9e de vie car, \u00e0 l'instar des moteurs, les compresseurs ont un courant de d\u00e9marrage tr\u00e8s \u00e9lev\u00e9, et des d\u00e9marrages fr\u00e9quents provoquent une surchauffe des bobines et la destruction du compresseur), le <\/span>R\u00e9gulateur de temp\u00e9rature PID<\/span><\/a><\/span> Dans un syst\u00e8me de r\u00e9gulation pr\u00e9cise de la temp\u00e9rature de chauffage, l'\u00e9l\u00e9ment chauffant contr\u00f4l\u00e9 est fr\u00e9quemment activ\u00e9 et d\u00e9sactiv\u00e9 afin de maintenir une temp\u00e9rature pr\u00e9cise.<\/span><\/p>

Gr\u00e2ce \u00e0 leur temps de r\u00e9ponse rapide et \u00e0 leur temps de commutation court, les relais statiques constituent un choix id\u00e9al et sont donc largement utilis\u00e9s dans les syst\u00e8mes de r\u00e9gulation de temp\u00e9rature pour le chauffage industriel, tels que les installations CVC et les appareils de chauffage.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t

2. \u00c9quipements d'automatisation pour l'industrie agroalimentaire et le conditionnement<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Le maintien d'une temp\u00e9rature ad\u00e9quate est essentiel dans la production alimentaire.<\/span><\/p>

Par exemple, on utilise des temp\u00e9ratures \u00e9lev\u00e9es pour la st\u00e9rilisation afin de prolonger la dur\u00e9e de conservation ; et dans l'industrie boulang\u00e8re, un contr\u00f4le pr\u00e9cis de la temp\u00e9rature rend le pain plus savoureux.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Dans ces secteurs, les r\u00e9gulateurs de temp\u00e9rature utilisent des actionneurs, tels que des relais statiques, pour commander les \u00e9l\u00e9ments chauffants, garantissant ainsi le maintien de la temp\u00e9rature requise.<\/span><\/p>

Les relais statiques sont \u00e9galement couramment utilis\u00e9s dans les \u00e9quipements d'emballage, notamment dans les processus de thermoscellage ou d'emballage sous film r\u00e9tractable qui n\u00e9cessitent un chauffage stable et pr\u00e9cis afin de garantir la qualit\u00e9 de l'emballage.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

3. Maison connect\u00e9e<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Le bruit est un facteur important \u00e0 prendre en compte dans la conception \u00e9lectrique des maisons connect\u00e9es.<\/span><\/p>

De nombreux contacteurs \u00e9lectromagn\u00e9tiques g\u00e9n\u00e8rent un bruit consid\u00e9rable lorsqu'ils se ferment, ce qui explique pourquoi on les trouve rarement dans les maisons connect\u00e9es.<\/span><\/p>

Gr\u00e2ce \u00e0 leur absence de bruit, les relais statiques peuvent \u00eatre utilis\u00e9s dans les syst\u00e8mes d'\u00e9clairage intelligents pour la maison connect\u00e9e, le chauffage \u00e9lectrique domestique, les prises intelligentes, les armoires de d\u00e9sinfection et les chauffe-eau \u00e9lectriques.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

4. D\u00e9marrage\/arr\u00eat du moteur et d\u00e9marrage progressif<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t\t\t\t\t

Pour \u00eatre honn\u00eate, <\/span>Contacteurs CA<\/span><\/a><\/span> sont plus couramment utilis\u00e9s pour le d\u00e9marrage et l'arr\u00eat des moteurs, mais si vous souhaitez utiliser d'autres produits pour remplacer les contacteurs CA, il est recommand\u00e9 d'opter pour des relais statiques.<\/span><\/p>

Dans certaines applications sp\u00e9cifiques, telles que les stations-service o\u00f9 sont pr\u00e9sents des gaz inflammables et explosifs, il est pr\u00e9f\u00e9rable d'utiliser des relais statiques monophas\u00e9s ou triphas\u00e9s pour commander les moteurs.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t\t\t\t\t

Une autre application des r\u00e9gulateurs de tension \u00e0 semi-conducteurs (un type de relais statique) est le d\u00e9marrage progressif des moteurs asynchrones \u00e0 courant alternatif. \u00c0 mesure que le signal de commande augmente ou diminue, le r\u00e9gulateur de tension \u00e0 semi-conducteurs peut augmenter ou diminuer sa tension de sortie en cons\u00e9quence, ce qui en fait une option \u00e9conomique pour le d\u00e9marrage progressif des moteurs.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t
\n\t\t\t\t\t

5. Instruments m\u00e9dicaux et d'analyse de pr\u00e9cision<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Les relais statiques peuvent \u00eatre utilis\u00e9s pour le contr\u00f4le de la temp\u00e9rature dans les incubateurs m\u00e9dicaux, les analyseurs biochimiques, les appareils de chauffage destin\u00e9s \u00e0 la kin\u00e9sith\u00e9rapie et les instruments d'analyse de laboratoire. Leurs interf\u00e9rences \u00e9lectromagn\u00e9tiques extr\u00eamement faibles et leur fonctionnement sans contact garantissent l'absence de perturbation des signaux de d\u00e9tection de pr\u00e9cision.<\/span><\/p>

Les instruments m\u00e9dicaux et de mesure de pr\u00e9cision n\u00e9cessitent des dispositifs de commutation plus fiables afin de garantir un haut niveau de fiabilit\u00e9. Les relais statiques, gr\u00e2ce \u00e0 leur vitesse de commutation \u00e9lev\u00e9e, leur fonctionnement silencieux et leur longue dur\u00e9e de vie (de 5 \u00e0 10 ans), constituent le choix optimal.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

6. Commande de l'\u00e9clairage de sc\u00e8ne et du mat\u00e9riel audiovisuel<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Les relais statiques trouvent \u00e9galement une autre application importante dans la commande de l'\u00e9clairage de sc\u00e8ne et des \u00e9quipements audiovisuels.<\/span><\/p>

En utilisant des signaux de commande de 3 \u00e0 32 V CC provenant de <\/span>automates programmables<\/span><\/a><\/span>, des Arduinos et des processeurs Raspberry, vous pouvez allumer ou \u00e9teindre instantan\u00e9ment et silencieusement des LED de 1 000 W ou 2 000 W.<\/span><\/p>

De plus, en l'absence d'interf\u00e9rences \u00e9lectromagn\u00e9tiques, les relais statiques peuvent \u00e9galement \u00eatre utilis\u00e9s dans des \u00e9quipements audiovisuels tr\u00e8s sensibles aux interf\u00e9rences \u00e9lectromagn\u00e9tiques.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t
\n\t\t\t\t\t

7. Sc\u00e9narios d'utilisation de produits chimiques inflammables et explosifs dans des environnements antid\u00e9flagrants<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Les relais statiques sont largement utilis\u00e9s dans les environnements antid\u00e9flagrants o\u00f9 sont pr\u00e9sents des produits chimiques inflammables et explosifs, tels que les ateliers p\u00e9trochimiques, les environnements poussi\u00e9reux et les atmosph\u00e8res contenant des gaz inflammables et explosifs, pour commander des pompes, des vannes, des dispositifs de chauffage, des ventilateurs antid\u00e9flagrants, etc.<\/span><\/p>

Les relais statiques se caract\u00e9risent par une commutation enti\u00e8rement \u00e9tanche, sans contact et sans \u00e9tincelles, ce qui permet d'\u00e9liminer les sources d'inflammation \u00e0 la source.<\/span><\/p>

Gr\u00e2ce \u00e0 leurs bo\u00eetiers antid\u00e9flagrants, les relais statiques r\u00e9pondent aux exigences applicables en mati\u00e8re de protection contre les explosions, et leurs performances en mati\u00e8re de s\u00e9curit\u00e9 intrins\u00e8que sont sup\u00e9rieures \u00e0 celles des contacteurs traditionnels.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Les machines \u00e0 commande num\u00e9rique (CNC) sont largement utilis\u00e9es dans la production m\u00e9tallurgique.<\/span><\/p>

Elles se composent de six parties : le syst\u00e8me de commande, le syst\u00e8me d'entra\u00eenement, les composants structurels, les \u00e9l\u00e9ments d'usinage, le syst\u00e8me de d\u00e9tection et de r\u00e9troaction, ainsi que le syst\u00e8me de refroidissement et de lubrification.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Les relais statiques peuvent \u00eatre utilis\u00e9s dans les syst\u00e8mes de refroidissement et de lubrification des machines-outils \u00e0 commande num\u00e9rique pour commander les pompes de refroidissement, les \u00e9lectrovannes hydrauliques, les voyants lumineux des postes de travail, les v\u00e9rins de serrage, etc. ; ils peuvent \u00eatre pilot\u00e9s directement par un automate programmable (PLC) au niveau du syst\u00e8me de commande.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

9. Syst\u00e8mes photovolta\u00efques et syst\u00e8mes \u00e0 courant continu utilisant les \u00e9nergies nouvelles<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t

Dans les installations solaires autonomes, les panneaux solaires produisent du courant continu (CC), qui est ensuite stock\u00e9 dans des batteries au lithium-ion ou au plomb-acide gr\u00e2ce \u00e0 des r\u00e9gulateurs de charge solaire fonctionnant par modulation de largeur d'impulsion (PWM) ou par suivi du point de puissance maximale (MPPT).<\/span><\/p>

Dans ce syst\u00e8me d'\u00e9nergie solaire en courant continu, le syst\u00e8me de gestion de batterie (BMS) peut utiliser des relais statiques (SSR) command\u00e9s en courant continu pour contr\u00f4ler la commutation du syst\u00e8me de stockage d'\u00e9nergie en courant continu. Il est \u00e9galement possible d'utiliser des relais statiques CC\/CA dans la section onduleur pour contr\u00f4ler la commutation de l'alimentation en courant alternatif de la charge.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

10. Syst\u00e8me de commutation de signaux et d'acquisition de donn\u00e9es<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Dans certaines applications, les modules \u00e0 relais statique peuvent remplacer les modules EMR dans les syst\u00e8mes de commutation de signaux et d'acquisition de donn\u00e9es.<\/span><\/p>

Vous trouverez ci-dessous une image du module :<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Ces modules de relais statiques peuvent \u00eatre \u00e0 un canal, \u00e0 deux canaux, \u00e0 quatre canaux, \u00e0 huit canaux, etc.<\/span><\/p>

En recevant des signaux de commande provenant d'un automate programmable ou d'autres compresseurs, ils peuvent ainsi contr\u00f4ler les charges individuellement, l'une apr\u00e8s l'autre.<\/span><\/p>

Par exemple, dans une machine \u00e0 sceller automatique, le premier canal commande le d\u00e9marrage et l'arr\u00eat du moteur, le deuxi\u00e8me canal commande l'\u00e9tat activ\u00e9\/d\u00e9sactiv\u00e9 de l'\u00e9lectrovanne, le troisi\u00e8me canal commande le chauffage et le quatri\u00e8me canal commande l'action de cisaillement.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

En r\u00e9sum\u00e9, les relais statiques ne sont pas seulement utilis\u00e9s dans les 10 applications mentionn\u00e9es ci-dessus, mais \u00e9galement dans de nombreuses autres applications qui ne sont pas \u00e9voqu\u00e9es ici.<\/span><\/p>
