Abstract
Disclosed is a non-contact power feeding apparatus using a conductive fluid, through which an electric railroad vehicle or a trolleybus receives required power from a contact wire in a non-contact state by using the conductive fluid. The non-contact power feeding apparatus according to the present invention includes: a fluid injection hole defined in a vehicle to inject the conductive fluid toward the contact wire; a conductive fluid container for supplying the conductive fluid that is injected through the fluid injection hole; a pressing pump for injecting the conductive fluid within the conductive fluid container through the fluid injection hole; and a current collection terminal disposed on a side of the fluid injection hole to receive the power from the contact wire in a non-contact manner by using the conductive fluid as a medium. According to the present invention, since the conductive fluid is injected toward the contact wire through the fluid injection hole to feed the power in a non-contact manner, wear-out of the power feeding apparatus and the contact wire does not occur and thus costs for maintenance and repair can be reduced.
