Guia prático de inspeção, manutenção e ensaios em disjuntores de alta tensão

Abstract

This work presents the main elements that make up the high voltage circuit breakers, their electrical characteristics, and the main inspections and tests performed during preventive maintenance. Thus, a procedure in the form of a work instruction that follows the standards and recommendations according to national and international standards with a detailed description regarding these tests is formed. The applications of these tests are also described, as well as the evaluation of the results obtained and consequences for the proper operation of the equipment. The concepts and foundations corresponding to high voltage circuit breakers were used, based on current national standards, in order to guarantee the necessary basis for the development of this work. In the context of the reasoning, the main characteristics and specifications applied to high voltage circuit breakers are included, which are indispensable for the completion of the tests. Finally, the practical performance of the maintenance tests discussed throughout the work is presented, with the objective of verifying the execution of the procedures, evaluating the appropriate operating conditions of the equipment. The results were analyzed and interpreted according to the requirements of standards and manufacturers
