Probing the effect of displacement on electrical contact tribological behavior at the risk frequency of nuclear safety DCS equipment
Purpose
This paper aims to study the tribological characteristics of the electrical contact system under different displacement amplitudes.
Design/methodology/approach
First, the risk frequency of real nuclear safety distributed control system (DCS) equipment is evaluated. Subsequently, a reciprocating friction test device which is characterized by a ball-on-flat configuration is established, and a series of current-carrying tribological tests are carried out at this risk frequency.
Findings
At risk frequency and larger displacement amplitude, the friction coefficient visibly rises. The reliability of the electrical contact system declines as amplitude increases. The wear morphology analysis shows that the wear rate increases significantly and the degree of interface wear intensifies at a larger amplitude. The wear area occupied by the third body layer increases sharply, and the appearance of plateaus on the surface leads to the increase of friction coefficient and contact resistance. EDS analysis suggests that oxygen elements progressively arise in the third layer as a result of increased air exposure brought on by larger displacement amplitude.
Originality/value
Results are significant for recognizing the tribological properties of electrical connectors in nuclear power control systems.
