Title:
MAGNETIC CORE HOLDER OF POWER DISTRIBUTION APPARATUS
Document Type and Number:
Japanese Patent JP2016011873
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a ground connection structure of a magnetic core that inexpensively allows connection of the magnetic core to the ground without increasing connection man-hour, does not adversely affect performance of a power distribution apparatus, and has a shortened lead time.SOLUTION: Current lines 36, 36 are inserted into cylindrical parts 31a, 31a, magnetic cores 32, 32 are stored in magnetic core storage parts 31b, 31b, and thus the magnetic cores 32, 32 surround the current lines 36, 36 and are held by a magnetic core holder 31 while being insulated and separated from the current lines 36, 36. A connection conductor 33 is stored in a connection conductor storage part 31d, a voltage line 39 of a ground phase is inserted into an insertion hole 31c, and thus the connection conductor 33 contacts the magnetic cores 32, 32 through first gap parts 31d1, 31d1, and contacts the voltage line 39 through a second gap part 31d2. The magnetic cores 32, 32 are electrically connected to the voltage line 39 through the connection conductor 33, accordingly.
