材を提供することを目的としたものである。A train such as a Shinkansen runs by converting an AC power supply from an overhead line into a DC power supply. A device called a "main circuit smoothing reactor" mounted under the floor of a train is used to convert the AC power into DC. Leakage magnetic flux emitted from the “main circuit smoothing reactor” is considered to be the main cause of rail magnetization. On the other hand, iron powder generated by friction between train wheels and rails,
Alternatively, iron powder or other metal powder generated by the friction between the rotating disc and the brake shoe when the train applies the brakes falls on the upper surface of the rail, particularly near the insulation between the rails at the rail connection (ie, The iron powder and iron pieces that have fallen into the vicinity of the insulation surrounded by X in FIGS. 4 and 5 are attracted to the ends of the magnetized rails and accumulated, and eventually ride over the rail-type insulating plate 1 between the rails to form a bridge (short circuit). ). As a conventional countermeasure to eliminate such a problem, when insulating and connecting the rails, silicon is filled around the rail joints,
The space is filled so that iron powder and iron pieces do not enter. However, in such conventional measures, it takes time and effort to fill silicon. Although the rail insulation is dismantled and cleaned periodically, there is a problem that cleaning must be performed frequently since iron powder and iron chips are immediately deposited on the rail insulation. Was. The present invention
It is an object of the present invention to provide a rail insulating member that can solve the above-described problems.
