Then, you can want them to try the working mechanism of the pantograph on their own computers. In this step, students have already know what is ratio thus, you may ask them to find ratios. Also, you can mention a little about the construction and say EF// DH and ED//FH because it is important for the similarity.The pantograph current collector is used in the railways for collection of current from the overhead system where the operating speed of the train is as high as 100 kmph to 130 kmph and the current to be collected are as large as 2 kA to 3 kA. The pantograph is mounted on the roof of the vehicle and carry a sliding shoe for contact What is Pantograph Collector in Electric Traction?

To reduce drawing A, the pantograph is fixed at the pole P. With the adjustable bars, the given ratio is defined. With the tracer point T the outline of drawing A is traced. The drawing pen D produces a similar figure in the chosen scale. Exchanging the drawing pen and the tracer point enlarges the figure.Under different operating speeds, the air produces a certain dynamic lifting force on the pantograph, which is based on the average lifting force target curve of the pantograph mentioned in the standard TB 3271 [].The static lifting force and aerodynamic force of DSA250 pantograph are 70 N and 0.00097v 2 N, respectively..
