The input parameters are continuously adjustable. Suffered from intensive arc erosion with high frequency, the worn surface of the strip in Figure 13 b was destroyed dramatically. Large erosion pits were produced, as seen in Figure 11 d, which coincided with the 3D surface morphology in Figure 8 c. Analysis Cookies Analysis cookies help Heraeus to understand how people like to use our website, so that we can improve it. Checon's cladding capabilities are able to provide cost effective material solutions, such as precious metal alloys, by combining the unique properties of two or more materials therefore optimizing the most desirable characteristics of each material. To have better understanding of this, XPS was carried out on the worn surfaces in Figure 11 a and Figure 13 c which were produced by low arcing rate 0.
US5041702A - Contact strip for pantograph used on electric railcar - Google Patents
The effects of frequency and amplitude on arcing rate were studied firstly. Effect of the vibration on friction and wear behavior between the carbon strip and copper contact wire pair. By using these cookies, we can tailor information to your needs and display relevant information within and outside of our website. Lubrication mechanisms of a sliding contact by simultaneous action of electric current and magnetic field. These influences at high velocities became much more significant.
Strip for electrical applications Copper | Distribution and Solutions in non-Ferrous Metals
In general, the increase of amplitude from 8 N to 41 N induced the raising of the arcing rate and deterioration of the surface quality which left a number of arc erosion pits on the worn surface. The present invention proposes to simplify the number and assembly of components known ramps, as well as the realization of a rail that can easily be curved to follow large curvatures. Buttons Bi-layer or Tri-layer buttons are available with weldable backing and numerous welding patterns. The faster the train ran, the more influence the action of f and B had. The physical properties of the pure carbon strip are exhibited in Table 1. Strong erosion morphology was observed at this high arcing level. There may be a circular opening 12, 32 at the end of each plate, for receiving the end of a festoon bulb schematically in the drawing under reference
Checon's cladding capabilities are able to provide cost effective material solutions, such as precious metal alloys, by combining the unique properties of two or more materials therefore optimizing the most desirable characteristics of each material. Figure 4 is a side view of the clip of Figure 3. It simplifies manufacturing process of electrical parts with high productivity and low cost and raises the assembly precision credibility of electrical component. During assembly, the pads 31 of the lower conductive strip easily burst the adhesive layer 20 when projected in the transverse slots 13 of the upper conductive strip. Understanding pantograph arcing in electrified railways — influence of various parameters. Finally, electric current, light intensity, and dynamic contact force were sent to a PC for further study after wear tests. AT Date of ref document:
