Abstract :
For understanding the law that the trend of contact resistance follows the changed current, an equipment which was made up of an intelligent multi-function data acquisition, cooperated with PC programs, for measuring contact resistance was developed. The scanning electron microscopy(SEM) and Energy Dispersive Analysis System of X-ray were used to analyse the microstructure of contact. By observing the microcosmic appearance and analysing the component of contact, the failure reasons was confirmed.
