Manutenção centrada em confiabilidade aplicada à gestão de linhas de transmissão localizadas em áreas de ocupação irregular de faixa de passagem.

Abstract

This work aims at applying the methodology Reliability Centered Maintenance - RCM, through a pilot project in a maintenance unit transmission lines of the Companhia Hidro Elétrica do São Francisco – Chesf. Due to the difficulties of eliminating the problems of occupation range of transmission lines, the objective of this methodology is to reduce the risk of injury to persons occupying these areas through the change process in the maintenance of transmission lines. Initially the presentation of the most critical components of the transmission lines on the viewpoint of security, and identification of their major failure modes is taken as well as the methodologies for maintenance of transmission lines used today. The deployment process is done systematically and following the classic strategy and sequenced that is the selection of the system and information collection, analysis of failure modes and effects, the selection of the significant functions and activities applicable to assessment effectiveness of activities, then the selection of effective activities is made the frequency of activities to finally be set. Verifies the effectiveness of the methodology, since after the requisite tests, it is concluded that a different methodology for the maintenance of transmission lines present in areas of irregular occupation of track is required in addition to application of Reliability Centered Maintenance brings us to our goal is the reduction of existing risks in these transmission lines.
