Claim 0:
1. A magnetic induction power supply device installed on a power line, comprising:
a current transformer installed on the power line and comprising a first core, a second core and two or more coils having first and second coils that are wound on at least one of the first core and the second core;
a breaking unit connected to at least one of the two or more coils;
a rectification unit configured to rectify a voltage induced from at least one of the two or more coils: and
a switching unit configured to connect at least one of the two or more coils to the rectification unit,
wherein both ends of the first coil are connected to the switching unit, and both ends of the second coil are connected to the switching unit,
wherein the breaking unit forms a closed circuit along with the at least one of the one or more coils so that a mode of the current transformer changes into a short circuit mode in which the first core and the second core are able to be separated, and
wherein the breaking unit comprises:
a first breaking unit connected to both ends of the first coil in parallel and forming a closed circuit along with the first coil so that the mode of the current transformer changes into the short circuit mode; and
a second breaking unit connected to both ends of the second coil in parallel and forming a closed circuit along with the second coil so that the mode of the current transformer changes into the short circuit mode, and
wherein the first breaking unit and the second breaking unit comprise:
a switch forming a closed circuit along with one of the first coil or the second coil, and
a damping element connected to the switch in series to consume a current flowing into the closed circuit.
