Title:
NONCONTACT POWER SUPPLY FACILITY AND BRANCH BOX FOR USE THEREIN
Document Type and Number:
WIPO Patent Application WO/2002/037642
Kind Code:
A1
Abstract:
A noncontact power supply facility comprising a magnetic body (12) having a hole part (11) for passing a primary-side first induction line (2), a primary-side second induction line (5) for effecting a noncontact power supply to a load and passing the hole part (11) of the magnetic body (12), an additional line (17) passing the hole part (11) of the magnetic body (12), and a first a contact (19) for short-circuiting the additional line (17). According to the arrangement, power supply to the primary-side second induction line (5) can be interrupted through short circuit of the first a contact (19) and the load (secondary-side power receiving circuit) can be disconnected without switching a power supply line mechanically.
