Energy is concentrated in the contact surface and in the nea
Arc discharge process, arc root produces the thermal physical process due to concentrated energy release in the contact surface and near surface layer, caused by melting and evaporation of silver contact materials, this is silver contact electric ablation. In the breaking current small and short ...Read more -
Relay contact protection and contact matters
We know that the contact relay should be more cruel than the general Mosfet, the relay load is much larger than Mosfet. Common DC load DC motor, DC clutch and DC solenoid valves, these perceptual load switch is closed, hundreds or even thousands of volts of back electromotive force caused by the ...Read more
