Abstract
A power supply device comprises a capacitance (Ca) consisting of an overhead power line (100) and an electrode (20) extending in the longitudinal direction of the overhead power line (100) via an insulator (30), an inductance (La) connected in parallel with the capacitance (Ca), and an output portion (50) led out from both ends of a parallel circuit including the capacitance (Ca) and the inductance (La). The parallel circuit is operated as a parallel resonant circuit and power is supplied from the output portion (50), thereby obtaining a compact and simple structure and improving power supply efficiency to a load as compared with a conventional power supply device.
Claims15
An electric power supply apparatus attached to an overhead line to supply an electric power to a load, comprising:
- an electrode extending along said overhead line in a longitudinal direction thereof, with a dielectric being intervened therebetween;
- a capacitor defined by said overhead Line said dielectric and said electrode;
- an operation capacitance existing between said electrode and the ground so as to be in series to said capacitor;
- an inductor that is connected at one end to said electrode and at the other end to said overhead line so as to be in parallel to said capacitor;
- and
- an output section drawn from both ends of a parallel circuit including said capacitor and said inductor,
- wherein said parallel circuit is formed as a parallel resonance circuit, so that an electric power is output from said output section.
