Arcing and Quenching of the Contacts Contaminated with Sea Water |
| Abstract |
The failure and erosion of relay contacts mainly depend on the presence of particles deposited on the contact surface in various contaminated atmospheres. In this paper, the effects of sea water and circuit parameters on the arcing and quenching of magnet relay contacts are studied. The sea water pollutants of relay contact surface have led to increase the arcing numbers on making contact, and the mean arc durations on breaking contacts. Moreover, the maximum surge voltage and mean arc duration between relay contacts are also varied significantly by the circuit parameters. The effects of the spark quenching circuits using condenser of diode on the arcing of contacts are also discussed. |
