APPARATUS AND METHOD OF DETERMINING STATUS OF CIRCUIT BREAKER IN SWITCHGEAR

Embodiments of the present disclosure provide an apparatus and a method of determining a status of a circuit breaker in a switchgear. The apparatus comprises a temperature indicator arranged on the circuit breaker and configured to change an appearance property in response to a change of a temperature of the circuit breaker; an image capturing device configured to capture images of the circuit breaker; and a processor configured to: determine a movement status of the circuit breaker at least by detecting a change of a position of an edge of the temperature indicator across the images; and determine a temperature of the circuit breaker by detecting the change of the appearance property of the temperature indicator across the images. With the above arrangements, the status of the circuit breaker including the temperature and the movement status can be determined by analyzing the images captured by the image capturing device. In this way, an operator can receive more valuable information without having to keep watching the video of the circuit breaker timely, thereby improving the control efficiency and effectiveness.
