摘要:
The power supply installation for a direct current railroad comprises two diode bridge-connected circuits, only two thyristor breakers each connected in parallel to each of the two diode bridge-connected circuits, four dc disconnecting switches each connected between a diode bridge-connected circuit and one of four electric car power supply lines constituting a double track, separately. Further, the two diode bridge-connected circuits are connected by a dc disconnecting switch closed only in case of an accident. In case a ground fault occurs at a power supply line, a powering current to the defective line is interrupted by one of the breakers, together with an extension power supply current supplied from an adjacent substation, without exerting an influence of accident upon the other power supply lines. Further, even if one of the breakers is broken, powering currents are kept supplied to all the power supply lines through a mutual spare bus bar.

To provide a planar light source device that can provide large-area, uniform, and high-quality planar illumination light.A planar light source device includes a main body case 4 that surrounds the periphery of a gap between a pair of optical reflection plates disposed to face each other with side plates, and a plurality of point light sources 2 arranged at predetermined intervals on at least one side plate of the main body case. The planar light source device allows light from the point light sources 2 to be transmitted through at least one of the pair of optical reflection plates 5 and emitted to the outside. At least one 5 of the pair of optical reflection plates 5 includes a light blocking region S1 that blocks light from the point light sources on the point light sources 2 side, and a light transmission region S2 that does not allow the light from the point light sources 2 to be directly transmitted but allows reflection light reflected between the optical reflection plates to be transmitted, and is aligned so that transmissivity increases as the distance from the light blocking region S1 increases, and luminance is substantially uniform on the surface of the optical reflection plate.
