Dispositif de protection contre les surtensions vs. Protecteur de surtension contre. Parafoudre<\/h2>\r\n
Bien que ces trois termes visent \u00e0 fournir une protection contre les surtensions, ils pr\u00e9sentent des diff\u00e9rences subtiles mais cruciales dans les d\u00e9finitions techniques, les sc\u00e9narios d'application et les sp\u00e9cifications standard.<\/div>\r\n \r\n

Concept<\/h3>\r\n

Dispositif de protection contre les surtensions (SPD)<\/strong><\/h4>\r\n
Il s'agit d'un terme standard et professionnel, issu des normes de la Commission \u00e9lectrotechnique internationale (CEI) (telles que la CEI 61643-11). Il s'agit d'une cat\u00e9gorie compl\u00e8te de produits conformes \u00e0 des normes sp\u00e9cifiques, faisant r\u00e9f\u00e9rence aux dispositifs \u00e9lectriques utilis\u00e9s pour limiter les surtensions transitoires et les courants d'appel de d\u00e9charge, qui doivent contenir au moins un \u00e9l\u00e9ment non lin\u00e9aire.<\/div>\r\n
\"Protection<\/a><\/div>\r\n
<\/div>\r\n
Caract\u00e9ristiques : SPD est un terme d'ing\u00e9nierie mettant l'accent sur sa conformit\u00e9 aux normes internationales et ayant des param\u00e8tres de performance clairement d\u00e9finis (tels que Up, In, Iimp, etc.). C'est un terme standard utilis\u00e9 dans la conception \u00e9lectrotechnique.<\/div>\r\n \r\n

Protecteur de surtension<\/strong><\/h4>\r\n
Il s\u2019agit d\u2019un terme plus familier et commercial, particuli\u00e8rement largement utilis\u00e9 sur le march\u00e9 nord-am\u00e9ricain. Il fait g\u00e9n\u00e9ralement r\u00e9f\u00e9rence aux produits de protection au niveau des appareils finaux, le plus souvent des multiprises dot\u00e9es de prises multiprises.<\/div>\r\n
Caract\u00e9ristiques : Il appartient \u00e0 la cat\u00e9gorie SPD (Approvisionnement, Protection et Distribution), mais fait g\u00e9n\u00e9ralement r\u00e9f\u00e9rence \u00e0 des produits avec des niveaux de protection inf\u00e9rieurs (comme le type 3). Ce terme est davantage ax\u00e9 sur le march\u00e9 de consommation et la communication de masse.<\/div>\r\n \r\n

Parafoudre<\/strong><\/h4>\r\n
Il s'agit d'un terme traditionnel et sp\u00e9cifique, utilis\u00e9 \u00e0 l'origine principalement dans les syst\u00e8mes de transport et de distribution d'\u00e9lectricit\u00e9, tels que la protection des sous-stations et des lignes a\u00e9riennes contre les coups de foudre directs ou les surtensions induites par la foudre. Dans le domaine de la basse tension, il fait parfois sp\u00e9cifiquement r\u00e9f\u00e9rence aux SPD de type 1, qui sont des dispositifs de protection capables de r\u00e9sister \u00e0 une partie du courant de foudre continu avec une forte capacit\u00e9 de d\u00e9charge.<\/div>\r\n
Caract\u00e9ristiques\u00a0: Souligne sa puissante capacit\u00e9 de d\u00e9charge pour faire face aux surtensions de foudre les plus s\u00e9v\u00e8res.

Install a Type 1\/2 SPD in the main incoming line cabinet.<\/div>\r\n
Install Type 2 SPDs in front of each control cabinet, PLC cabinet, and frequency converter.<\/div>\r\n \r\n

Key Performance Parameters<\/h3>\r\n\"BR-30FU<\/a>\r\n
When selecting an SPD, be sure to pay attention to the following key parameters:<\/div>\r\n
Uc (Maximum Continuous Operating Voltage)<\/strong><\/div>\r\n
The SPD must be able to withstand the maximum AC or DC voltage for extended periods without starting. This voltage must be higher than the nominal voltage of the local power grid. For example, in a 230V area, Uc should be at least 275V or higher.<\/div>\r\n \r\n
Iimp (Impact Current)<\/strong><\/div>\r\n
For Type 1 SPDs, this indicates the maximum peak lightning current it can withstand with a 10\/350\u00b5s waveform. The higher the value, the stronger its resistance to direct lightning strikes.<\/div>\r\n \r\n
Uoc (Open Circuit Voltage)<\/strong><\/div>\r\n
Primarily used for testing and defining the performance of Type 3 SPDs, it represents the waveform of the test voltage applied to the SPD.<\/div>\r\n \r\n
Up (Voltage Protection Level)<\/strong><\/div>\r\n
This is one of the most important parameters, representing the residual voltage across the SPD after it trips. The Up value must be lower than the withstand voltage level of the protected equipment. The lower the value, the better the protection effect.<\/div>\r\n \r\n
In (Nominal Discharge Current)<\/strong><\/div>\r\n
