Title:
Leak sensing device
Document Type and Number:
Japanese Patent JP5911065
Kind Code:
B2
Abstract:
There is a limit on the miniaturization of electric leakage detecting apparatuses including a ring-shaped magnetic material. Any thicker electric wires increase the size of the ring-shaped magnetic material. Additionally, it is difficult to place the ring-shaped magnetic material around the electric wires that have already been placed. In light of the foregoing, an electric leakage apparatus is provided. The electric leakage detecting apparatus is to be installed on a pair of power source lines connecting a power source and a load, and includes: a pair of holders configured to hold the power source lines, respectively; a fixing means configured to fix the holders at a predetermined interval; a pair of magnetic elements each placed on each of the holders while being parallel to the power source lines; a detecting means configured to detect a difference between magneto-resistance effects of the magnetic elements; and a driving means configured to feed a drive current to the magnetic elements.
