Title:
SELF-POWER GENERATING SMART CURRENT SENSOR
Document Type and Number:
WIPO Patent Application WO/2019/045260
Kind Code:
A1
Abstract:
The present invention relates to a hardware-type self-power generating smart current sensor for allowing an existing method using an embedded battery or external commercial power for supplying power to the smart current sensor to be replaced with a self-power generating method, so as to improve operating life of the smart sensor to be semi-permanent and to unify the sensor and a power supply device, and an elliptical core in which a pair of U-shaped first and second core parts make contact with each other to be symmetrical to each other is provided, and a bobbin for winding up a secondary winding is assembled to one side of the first core part of the core, wherein an assembly of the core and the bobbin is mounted in a printed circuit board through a plurality of bobbin legs formed in the bobbin, the secondary winding and the printed circuit board are electrically connected through at least one of the plurality of bobbin legs, and an assembly of the core, the bobbin and the printed circuit board is accommodated in a case.
