Operação e manutenção de equipamentos elétricos em subestações distribuidoras

Abstract

This work presents the operation of the main equipments installed in distributing substations and how the concessionaires of distribution of energy work to maintain these equipments in the electrical system providing the necessary maintenance to avoid failures. The equipment to be in continuous operation must be kept in operating conditions defined by the manufacturer, but to the detriment of time actions, functional wear and tear, the equipment needs to be assisted under maintenance procedures in order to avoid defects that remove it of the electrical system. On the other hand, the study and the collection of information about these equipments developed in the work the most important aspects realized by the maintenance departments of the distribution concessionaires. In the work, a qualitative approach is taken on how inspections thermographic, visual and ultrasonic take place in order to bring the work closer to the practical experience of substation maintenance. Then, a grouping of the tests carried out to verify the operation of the equipment was carried out, tests that follow the minimum periodicity of the maintenance planprovided and directed by ANEEL.
