Power device monitoring system
The present disclosure relates to a power device monitoring system comprising: a cradle having a cradle terminal formed on the rear side thereof; a circuit breaker mechanically or electrically connected to or separated from the cradle terminal; at least one position detection means mounted inside the circuit breaker so as to detect the position of a circuit breaker body in real time; and a display unit for outputting the mobile characteristic of the circuit breaker body detected by the position detection means.
1. 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 linearly and in real time over an entirety of a movement range of the circuit breaker body; and
a display for outputting movement characteristics of the circuit breaker body detected by the position detecting means.
2. The system of claim 1 , wherein the movement characteristics of the circuit breaker body output from the display includes at least one of a movement distance of the circuit breaker body, a remaining distance thereof to a contact or disconnection position, a movement speed thereof, change in the movement speed thereof, a contact amount between the circuit breaker body and the cradle terminal, or an expected time duration for which the circuit breaker body has been inserted.
3. The system of claim 1 , 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.
4. The system of claim 1 , wherein the position detecting means includes:
a position detected area portion formed on at least one of both opposing side faces of the circuit breaker body;
a sensor module including at least one sensor facing the position detected area portion so as to detect a displaced position of the position detected area portion and thus detect a position of the circuit breaker body, based on the detect displaced position, wherein the sensor module is fixed to at least one of both opposing inner faces of the cradle; 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.
5. The system of claim 3 , wherein the controller is configured to:
when a contact amount between the circuit breaker body and the cradle terminal exceeds a preset allowable range of the contact amount while the circuit breaker body is at a contact position, generate a notification alarm, and output the generated notification alarm to the display.
6. The system of claim 3 , wherein the controller is configured to:
when at least two values of a movement characteristic of the same type of among the movement characteristics of the position detected area portion detected by the sensor module are detected, compare the at least two values with each other; and
when a difference between the at least two values exceeds a preset error tolerance, generate a notification alert, and output the generated notification alert to the display.
7. The system of claim 3 , wherein the sensor module includes at least one of a non-contact type sensor or a contact type sensor.
8. The system of claim 3 , wherein the position detected area portion includes at least one of:
a position sticker having a shade varying in a movement direction of the truck;
a plurality of position protrusions, wherein at least one of a number, a shape, or a position thereof varies in the movement direction of the truck; or
a position inclined portion having one face inclined downwardly or upwardly in the truck movement direction.
9. The system of claim 8 , wherein the sensor module further includes a contact type sensor configured to contact the position inclined portion and to detect a varying height of the position inclined portion and to detect the position of the circuit breaker body based on the detected varying height.
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.
11. 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 detected area portion formed on at least one of both opposing side faces of the circuit breaker body;
a sensor module including at least one sensor facing the position detected area portion so as to detect a displaced position of the position detected area portion and thus detect a position of the circuit breaker body, based on the detect displaced position, wherein the sensor module is fixed to at least one of both opposing inner faces of the cradle; and
