Silicone contamination is one of well-known reasons of contact failures. It has been reported that siloxane component emitted from silicone-including polymeric materials is dissolved and converted into SiO2 due to arc discharges upon relay operations, deposited onto contact surfaces, resulting in a significant increase in contact resistance.
In this paper, a new acryl-based polymeric material (containing no silicone components) was evaluated with respect to its effects on contact resistance characteristics of relay contacts at ambient temperature of 120ºC. More specifically, a commercially-available mechanical relay (AgSnIn contacts) was sealed into a can with the material, and placed in a heating chamber to operate 40,000 break operations of an inductive DC14V-0.4A current and a resistive DC14V-1A current. The same experiments were also conducted with two types (a normal grade and a countermeasure grade against contact failures) of silicone-containing polymeric materials. As a result, in both load conditions, relays sealed with the acryl-based polymeric material showed no deterioration in contact resistances, while relays sealed with the normal-grade silicone-containing polymeric materials showed deteriorated contact resistances. In the inductive DC14V-0.4A load circuit, the silicone-containing material of the counter-measure type also induced significant fluctuations in the contact resistances. |
