Title (EN) WIRELESS SYSTEM FOR MEASURING VOLTAGE DISTRIBUTION OF ARRESTER
(FR) SYSTÈME RADIO DE MESURE DE LA DISTRIBUTION DES TENSIONS D'UN PARASURTENSEUR
(ZH) 避雷器电压分布无线测量系统
Abstract: front page image
(EN)A wireless system for measuring voltage distribution of arrester acquires the voltage of each node of the arrester synchronously by a wireless transmission method. The voltage of a transformer can be measured by a host(2), and the acquisition of the voltage is only at an interval of 0.6ms with the acquisition of the voltage of the node of the arrester by each voltage measuring probe(1), so measuring accuracy cannot be influenced. A discrete Fourier transform method is applied in signal processing to analyze and calculate the acquired voltage signal. An interference harmonic wave is filtered and base wave voltage is accurately calculated to ensure the measuring accuracy.
(FR)La présente invention concerne un système radio, qui est conçu pour mesurer la distribution des tensions d'un parasurtenseur, et qui acquiert de façon synchrone, grâce à un procédé de transmission radio, la tension de chaque nœud du parasurtenseur. L'invention permet ainsi à un hôte (2) de mesurer la tension d'un transformateur, l'acquisition de la tension étant réalisée par chacune des sondes de mesure de tension (1) à un intervalle de 0,6 ms par rapport à l'acquisition de la tension du nœud du parasurtenseur, ce qui fait que rien ne peut contrarier la précision des mesures. Un procédé à transformée de Fourier discrète est appliqué au traitement du signal de façon à analyser et calculer le signal de tension acquis. On filtre une onde harmonique interférante, et on calcule avec exactitude la tension de l'onde de base de façon à garantir une mesure exacte.
