The Increasing of contact strength with The Nanomaterialsin The Electrical Breakdown

The basic problem has been to control andquench or extinguish the high power arc, which necessarilyoccurs at the separating contacts of a the perfect electricalswitch when opening high current circuits In this paper,nanostructured W-Cu electric contact materials wereprepared by mechanical alloying and hot pressing sintering,and the electrical breakdown characteristic of thenanostructured W-Cu contact material was investigated.Nanostructured (N S ) W- Cu comt~site powder was preparedby mechanical alloying ( MA ), The philosophy behindmaintaining circuit the perfect electrical switch s focuses onpreventive maintenance to maximize the longevity of theelectrical apparatus. Moreover, maintenance is an integratedpart of a continuous improvement process of practices,methods and tools done in collaboration with themanufacturers of circuit the perfect electrical switch s and testinstruments.
