Description

Detailed Description of the Invention

The present invention is a system of a system that eliminates various friction and adverse phenomena between an overhead wire and a pantograph contact plate that occur when a train or an electric locomotive travels by using a contact plate with a pantograph overhead wire as a rotating roller from the plate.

Conventional pantographs for electric trains and electric locomotives are made of various plate materials on the contact surface with the overhead wire. Therefore, when a train / electric locomotive travels, the following adverse effects of friction occur.
(1) The overhead wire is worn out by friction.
(2) The contact plate surface of the pantograph is worn out by friction.
(3) Sparks are generated between the overhead wire and the contact plate of the pantograph. At the same time, radio waves are generated and radio interference occurs.
{Circle around (4)} Frictional heat is generated between the overhead wire and the contact plate of the pantograph, and both are greatly frictionally consumed.

Means for solving the problem

The contact plate surface of the pantograph that collects current from the overhead wire is changed from a plate to an automatic rotating roller, eliminating the friction phenomenon and making it a simple contact phenomenon.
Therefore

The adverse effects and losses of (1) to (4) can be eliminated to the limit. Power consumption can be saved by about 20%.

The motor speed of the built-in rotating roller is set so that the traveling speed and traveling distance of the pantograph's automatic rotating roller contact surface that travels in contact with the overhead line and the traveling speed and traveling distance of the traveling wheels of trains and electric locomotives completely match. Interlocked control.

1 is a vertical / horizontal / cross-sectional system of a pantograph of an automatic rotating roller contact surface according to the present invention.

Claims (2)

Pantographs, which are current collectors for trains and electric locomotives, are made of various materials on the contact surface with the overhead wire. Naturally, when a train or electric locomotive travels, a friction phenomenon occurs between the overhead wire and the contact plate of the pantograph. The friction phenomenon causes a wide variety of adverse effects. In order to eliminate the adverse effect to the limit, the contact plate surface of the pantograph that comes into contact with the overhead wire is contacted and collected by the surface of the automatically rotating roller. As a result, the system is characterized by the fact that the current collecting system is merely contact from friction and does not cause any harmful effects. The contact surface of the pantograph that contacts the overhead wire is brought into contact with the surface of the automatic rotating roller from the plate surface. The number of rotations of the roller is controlled so as to be proportional to the travel speed and travel distance. As a result, the contact surface of the automatic rotating roller of the pantograph that comes into contact with the overhead line changes from friction to a simple contact surface, and no adverse effect of friction occurs.
