1. R\u00e9acteur Imp\u00e9dance De Base: L'Approche Inductive-Nature Dominante<\/em><\/b><\/h3>\n

La fonction de base d'un r\u00e9acteur est de fournir contr\u00f4lable de l'inductance (L). Dans les basses fr\u00e9quences, son imp\u00e9dance (Z) est principalement d\u00e9termin\u00e9e par la r\u00e9actance inductive (X_L). Saisissant cette relation est la cl\u00e9 de la ma\u00eetrise d\u00e9pendant de la fr\u00e9quence du comportement.<\/p>\n

1.1 Formule De Base Et Physique De Base:<\/h4>\n

Ainsi, X_L augmente lin\u00e9airement avec la fr\u00e9quence\u2014une propri\u00e9t\u00e9 fondamentale de l'inductance.<\/p>\n

(2) le R\u00f4le de l'Inductance (L):\u00a0<\/strong><\/h6>\n

Une hausse de l'inductance (\u2191L) g\u00e9n\u00e8re fort en arri\u00e8re de la FEM pour la m\u00eame di\/dt, l'augmentation de X_L de fa\u00e7on lin\u00e9aire.<\/p>\n

1.3 Conclusion:<\/h4>\n

Id\u00e9al pour les inductances ou dans les basses fr\u00e9quences, le r\u00e9acteur imp\u00e9dance \u2248 X_L (= 2nfL), la hausse de fa\u00e7on lin\u00e9aire avec la fr\u00e9quence. C'est la base pour la compr\u00e9hension du r\u00e9acteur caract\u00e9ristiques de fr\u00e9quence.<\/p>\n

2. La puissance de la Gamme de Fr\u00e9quence (50\/60Hz): stabilit\u00e9 de l'Imp\u00e9dance pour la Compensation de puissance R\u00e9active & de Limitation de Courant<\/em><\/h3>\n

\"1\uff081\uff09\"<\/b><\/a><\/p>\n

<\/b>Harmoniques (multiples entiers de la fr\u00e9quence d'alimentation, par exemple, 3e\/150 hz, 5\/250Hz) proviennent de charges non-lin\u00e9aires (par exemple, les onduleurs, redresseurs).<\/p>\n

3.1 Changements D'Imp\u00e9dance:<\/strong><\/h4>\n
(1) X_L augmente lin\u00e9airement avec la fr\u00e9quence (par exemple, 5e harmonique X_L = 5\u00d7 fr\u00e9quence d'alimentation X_L).<\/strong><\/h6>\n
