Abstract
"SISTEMA DE CONTATO SEM SOLDA PARA CONTATORES ELETROMAGNéTICOS E MéTODO PARA EVITAR SOLDA DE CONTATO SOB CONDIçõES DE FALHA EM UM CONTATOR". Um sistema e método para evitar solda de contato sob várias condições de corrente falha são divulgados. O sistema inclui um contator (10) tendo contatos estacionários e móveis (42, 50) pressionados um contra o outro e comutáveis entre uma posição aberta e uma posição fechada. A energização de uma bobina eletromagnética (82) engata os contatos (42, 50) criando uma trajetória elétrica para corrente fluir através do contator (10). Modulação de largura de pulso é usada para abaixar a energia para a bobina (82) e manter os contatos (42, 50) na posição fechada. O contator (10) está equipado com defesas para impedir soldagem de contato. Sob correntes falhas baixas, a soldagem é impedida pela composição do material do contato. Sob correntes falhas intermediárias, os contatos (42, 50) são abertos e permanecem abertos usando componentes magnéticos (62, 64) até que o arco se dissipe e os contatos (42, 50) tenham resfriado suficientemente. Sob correntes falhas altas, o arranjo (32, 62, 64) faz os contatos abrirem e separam a armadura (70) da bobina (82) impedindo o re-engate dos contatos (42, 50) até que a bobina (82) seja energizada novamente.
