Abstract
The present disclosure relates to a circuit breaker opening/closing assistance apparatus for correcting a thermal image of a circuit breaker on the basis of a visible image of the circuit breaker, and assisting an opening/closing operation of the relevant circuit breaker on the basis of a temperature identified through the corrected thermal image. Further, the present disclosure relates to a circuit breaker opening/closing assistance apparatus for identifying a temperature of a circuit breaker in which a failure has occurred, on the basis of a thermal image of the circuit breaker, and assisting an opening/closing operation of the relevant circuit breaker on the basis of the identified temperature.
Claims20
A device for assisting opening and closing of a circuit breaker connected to and disposed between a power system and a load, the device comprising:
- a material identification unit configured to acquire a visible image of the circuit breaker using a light source, and identify a material imaged on the acquired visible image;
- an image correction unit configured to acquire a thermal image of the circuit breaker, and correct the thermal image based on emissivity of the identified material;
- a diagnosis unit configured to:
- identify a normal operation state of the circuit breaker based on a temperature value detected on the corrected thermal image;
- and
- compare the identified normal operation state with a current operation state of the circuit breaker and diagnose absence or presence of failure of the circuit breaker based on the comparison result;
- and
- a controller configured to generate a control signal based on the absence or presence of the failure of the circuit breaker, and provide the generated control signal to the circuit breaker.
A device for assisting opening and closing of a circuit breaker having a plurality of temperature sensors disposed thereon, the device comprising:
- a compensation unit configured to compensate for a temperature value of a thermal image of the circuit breaker, based on a first temperature detected on the thermal image of the circuit breaker and a second temperature provided from each of the plurality of temperature sensors;
- a diagnosis unit configured to:
- identify a normal operation state of the circuit breaker based on a temperature value detected on the compensated thermal image;
- and
- compare the identified normal operation state with a current operation state of the circuit breaker and diagnose absence or presence of failure of the circuit breaker, based on the comparison result;
- and
- a controller configured to generate a control signal based on the absence or presence of the failure of the circuit breaker, and provide the generated control signal to the circuit breaker.
