Standard guide for measuring voltage drop on closed arcing contacts
Electrical arc contact
Electrical arc contact
At present , the arc contacts in sfe switches is formed by the excellent property of electrical arc resistance of cu w alloy and the eminent conductivity together with high elasticity of crcu alloy , so - called cuw / crcu integrated contact
Switches play transmitting and cutting electrical current role during the working electrical net as a hinge , the important role will be brought into effect by the key part in switches - arc contact . if the contacts have invalidated and could not accomplished the important role during the working electrical net , switches would detonate , which result in the paralysis of whole net linked by the switches , the higher the transmitting voltage of net is , the bigger the affected area is , therefore , in order to decrease or avoid the arc eroding and invalidation during the net working , it is necessary to study the arc eroding and invalidation mechanism of contacts , sequentially make the whole net stable
