Análisis de los efectos que produce el arco eléctrico en tableros industriales mediante mediciones indirectas de ultrasonido pasivo.

Abstract

This thesis is intended to carry out the Analysis of the Effects Produced by the Electric Arc on industrial boards by means of direct measurements of passive ultrasound. In this aim, a support structure for the elements contained in the testing module was made, which consist of electric and dielectric elements intended to generate a determined failure mode from a manual regulation device with the aim to determine the probable potency outage as well as the loss and high electrical power consumption. The passive ultrasound is an analysis technique based on the condition that allows visualizing and listening the spectrum and frequency decibel as the electrical power supply is being done to the failure device. To show how the electrical arc generation occurs, energy consumption devices were used, which generate a 10-ampere load. The procedure followed for measuring the decibels generate by the electrical arc consisted of targeting the 15000- ultraprobe in the direction to the fail device so that it allows automatically observes the corresponding spectrum in the scream and, additionally three points of measures as well as the voltage and intensity values were taken in order to determine the potency and electrical power consumption and thus to compliment the study by making a comparison between the device undergone a 3,3 amperes load ( normal load) and 8,15 amperes load ( over load) and also, the relation between the electrical arc generation and the high electric power consumption. This analysis composition technique enables the decibel signal analysis, which are produced by the electrical arc in the industrial boards preventing the from fails. Therefore, to prevent a possible malfunction of the 15000-ultaraprobe, it is advisable to be familiarized with usage in advance.
