Um modelo fuzzy para estimar a durabilidade dos transformadores de alta tensão dos energizadores de cerca.

Abstract

Electric fences to deter animals from crossing a boundary are widely used in the modern farming. The fence charger, device that releases an electrical pulse along a connected bare wire, it’s the main component of an electric fence. In this work an statistic model was developed to estimate the durability of a fence chargers high voltage transformer, considering the conditions of the use and the physical characteristics of the installation place. fuzzy logic was used to modeling the electric fence system. In this work was used the MAMDANI’s inference model and in the defuzzification module was used the center-of-gravity method. The fuzzy model was implemented in a simulator to be used in the quality control process by an electric fence energizer manufacturer. The simulator presents an estimate value for the durability of the fence chargers high voltage transformer for the company’s interest regions, why each region has its soil electrical resistivity’s characteristics, what influences directly the grounding quality, that’s a basic component for the correct working of an electric fence system.
