Pronostic et stratégie de maintenance sur l'électronique de puissance

Abstract : This report presents the work carried out from March to July 2014 in the company Delipapier, located in Frouard, France. Delipapier produce toilet paper, paper towels and handkerchiefs to all sanitary and hygienic purposes. Their production combines mechanical and electronic equipments. The maintenance department has been recently facing a significant failure rate on a specific electronic power board used to control the motor shaft. They have set up a study in order to reach a normal failure rate, similar to the rest of electronic equipments. They want to develop a method of prognosis to supervise power boards. To reach this target, the current situation was formalized and analyzed. Critical components were identified and a prototype of prognosis program has been made to more accurately understand the wear of these components. In parallel, the study has shown the main cause of premature wear of power cards: heat. Changes in the cooling system control cabinets were performed; air conditioners have replaced the fans that equipped cabinets. Finally, a maintenance strategy has been developed to improve the maintenance of power electronic equipments and serves as a starting point for the development of a predictive maintenance method.
