Biasanya penurunan voltan sentuhan atau rintangan sentuhan geganti elektromagnet diperhatikan hanya untuk mengenal pasti sama ada sesentuh gagal atau tidak pada ujian hayat pengeluar. Walau bagaimanapun, sukar untuk mendedahkan kemerosotan prestasi sentuhan kerana variasi rintangan sentuhan mungkin tidak jelas. Dalam kertas kerja ini, teknologi ujian hayat baharu telah disiasat untuk menganalisis mekanisme kegagalan sentuhan dan proses degeneratif geganti elektromagnet dengan mengukur parameter masa mereka termasuk masa tutup, masa buka, masa lebih perjalanan, tempoh lantunan semula dan masa jurang semasa setiap operasi. Selain itu, untuk tujuan mengesahkan parameter masa, gerakan sentuhan dan morfologi sentuhan semasa ujian hayat direkodkan dengan menggunakan kamera berkelajuan tinggi. Kedua-dua variasi parameter masa dan maklumat yang diperoleh daripada foto yang diambil oleh kamera berkelajuan tinggi menunjukkan bahawa ia melibatkan tiga fasa degeneratif yang berbeza sepanjang hayat geganti. Keputusan juga menunjukkan kaedah ini adalah teknologi yang berkesan untuk mendiskriminasi dan mendiagnosis mekanisme kegagalan untuk geganti elektromagnet.

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.
