れていた。However, in recent years, the speeding up of electric vehicles has been remarkable, and along with this, the pantograph 1
Since the current collection per unit increases, the wear of the contact plate tends to increase remarkably. In addition, the number of pantographs tends to be reduced in order to prevent an increase in noise due to the increase in speed, and this also causes an increase in the abrasion of the contact plate along with an increase in the current collecting current. Furthermore, the increase of the current collection increases the Joule heat due to the contact resistance between the contact plate and the trolley wire, which may cause heating and fusing of the trolley wire.
There has been a demand for a pantograph siding plate material having wear resistance far superior to that of a conventional pantograph siding plate material and having a low resistivity.

よび表５表に示した。Next, the resistivity of these contact plates was measured (JIS E6301 pantograph contact plate resistance test method), the results are shown in Tables 4 and 5, and further accelerated wear test was conducted. In the accelerated wear test, one side of a disc with an outer diameter of 2.2 m supported upright by fixing the center to a horizontal rotating shaft of a motor was used as a simulated trolley wire, with an outer diameter of 2 m, a width of 15 mm, and a thickness of: Using a device in which a hard copper ring (JIS C1100 BB-H) having a dimension of 5 mm is eccentrically attached by 50 mm, the hard copper ring is pressed at two places on the diameter line with a pressing force of 50 N to length: 80 mm × width: 100 V between the simulated trolley wire and the grounding plate material while making surface contact with the dimension surface of 25 mm
Apply a direct current of 100A to the disk for 25 minutes in 5.5 minutes.
Increase the rotation speed to 0 km / h, hold at this speed for 5.5 minutes, then stop for 5.5 minutes, make this one cycle, and repeat this cycle three times. Also, the wear depth of the simulated trolley wire as the mating material was measured. From these measurement results, the specific wear amount and the value per 5000 times of the simulated trolley wire were calculated and shown in Tables 4 and 5.
