Resumen
The issue to be resolved in the current case study started from the observation of the large number of accidents involving electric services in the maintenance of medium-voltage circuit breakers. The objective of this study is to analyze the procedures, equipment and safety measures in the maintenance of circuit breakers in a pulp and paper industry based on the monitoring of the implementation of such activity in the plant chosen as an instrument of the case study. Seeking to support the analysis were presented guidelines of NR-10, beyond the guidelines about the operation, maintenance, existing types, testing and testing of circuit breakers.. For the case study was accompanied the two circuit breakers maintaining of different characteristics. A checklist with NR-10 items was designed to analyze the conformity and nonconformity. Reached a value of 91% serviced items and the main items failures was responsibility from the industry contractor of the service. From the analysis sought to propose improvements and security-related changes in the maintenance of circuit breakers.
