10. A monitoring system of a power device comprising:
a cradle having a cradle terminal disposed on a rear side thereof;
a circuit breaker configured to mechanically and electrically contact or be disconnected from the cradle terminal;
at least one position detecting means mounted inside the circuit breaker so as to detect a position of a circuit breaker body in real time; and
a display for outputting movement characteristics of the circuit breaker body detected by the position detecting means,
wherein the position detecting means includes:
a position bar including at least one position detected area portion extending in a corresponding manner to a movement range of the circuit breaker body, wherein one end of the position bar is coupled to a girder fixedly installed on a front face of the cradle, and the other end of the position bar acts as a free end facing the rear side of the cradle;
a sensor module installed inside a truck, wherein the circuit breaker body is loaded on the truck, and the position bar is inserted into the truck, wherein the truck is configured to reciprocate from the girder to the cradle terminal and inside the cradle, wherein the sensor module includes at least one sensor facing the position detected area portion; and
a controller configured to receive movement characteristics of the position detected area portion detected by the sensor module, and to detect the movement characteristics of the circuit breaker body based on the received movement characteristics of the position detected area portion.
