Normalmente a queda de tensão ou resistência de contato dos relés eletromagnéticos é observada apenas para identificar se os contatos estão com falha ou não nos testes de vida do fabricante. Contudo, é difícil revelar a degradação do desempenho do contato porque a variação da resistência do contato pode não ser óbvia. Neste artigo, uma nova tecnologia de teste de vida foi investigada para analisar os mecanismos de falha de contato e processos degenerativos de relés eletromagnéticos, medindo seus parâmetros de tempo, incluindo tempo de fechamento, tempo de abertura, tempo de sobrecurso, duração de rebote e tempo de intervalo durante cada operação. Além disso, com a finalidade de verificar os parâmetros de tempo, o movimento e a morfologia do contato durante o teste de vida foram registrados por meio de uma câmera de alta velocidade. Tanto as variações dos parâmetros de tempo quanto as informações obtidas nas fotos tiradas por câmeras de alta velocidade mostram que se trata de três fases degenerativas diferentes durante toda a vida de um relé. Os resultados também indicam que este método é uma tecnologia eficaz para discriminar e diagnosticar os mecanismos de falha de relés eletromagnéticos.

Abstract: Usually the contact voltage drop or contact resistance of electromagnetic relays is observed only to identify if the contacts are failure or not on the manufactures' life tests. However, it is difficult to reveal the contact performance degradation because the variation of contact resistance may not be obvious. In this paper, a new life test technology was investigated to analyze the contact failure mechanisms and degenerative processes of electromagnetic relays by measuring their time parameters including closing time, opening time, over-travel time, rebound duration and gap time during each operation. Moreover, for the purpose of verifying the time parameters, the contact motion and contact morphology during life test were record by using a high speed camera. Both the variations of time parameters and information obtained from photos taken by high speed camera show that it involves three different degenerative phases during the whole life of a relay. The results also indicate this method is an effective technology to discriminate and diagnose the failure mechanisms for electromagnetic relays.
