摘要： 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.

摘要： Embodiments of present disclosure relates to an electric device for sensing temperatures of hotspots of a switchgear. The electric device comprises an energy harvester, a first interface terminal and a wireless circuit. The energy harvester is configured to harvest energy of a switchgear. The first interface terminal is configured to interface with a second interface terminal of the switchgear to receive a first temperature signal from the second interface terminal. The first temperature signal indicates a first temperature sensed by a first temperature sensor in the switchgear. The wireless circuit is coupled to the energy harvester and the first interface terminal, and configured to wirelessly transmit a first wireless signal with power supplied from the energy harvester. The first wireless signal is associated with the first temperature signal. By utilizing embodiments herein, the electric device can be replaced without de-energization of the switchgear.

摘要： An apparatus (100) for measuring temperature of a switchgear (200) comprises: at least one sensor (101) arranged at or adjacent to a predetermined portion of the switchgear (200) and configured to sense a temperature of the predetermined portion; a transmission module (102) coupled to the at least one sensor (101) via a cable (1021) and configured to wirelessly transmit data representing the temperature; and a power module (103) coupled to a busbar of the switchgear (200) and configured to draw power from the busbar by induction and to supply the power to the transmission module (102) and the at least one sensor (101). On one hand, the number of the transmission module (102) is half or less than conventional solutions, reducing costs of the apparatus (100). On the other hand, the sensor (101) without the transmission module (102) has a tiny volume, which is more convenient to be installed in an appropriate location, such as in the tube (105), to obtain more accurate temperature data. Furthermore, the reduction in the number of parts such as the transmission module (102) also facilitates the installation of the apparatus (100) in the switchgear (200).

摘要： An apparatus (100) for monitoring a temperature and a voltage of a cable joint (201) of a cable (200) connected to gas insulated switchgear (300). The apparatus (100) comprises: an adaptor (101) adapted to be coupled to a cable socket (31) of the switchgear (300), a voltage detector (104) coupled to the adaptor (101) and configured to detect a voltage of the adaptor (101); a temperature sensor (102) arranged in the adaptor (101) and configured to detect a temperature of the adaptor (101); a processing circuitry (103) configured to determine the temperature of the cable joint (201) based on the detected temperature of the adaptor (101). A ground terminal (GND2) of the temperature sensor (102) is coupled to a ground terminal (GND1) of the processing circuitry (103), so as to electrically shield the processing circuitry (103) from the voltage of the adaptor (101). The both temperature and voltage of the cable joint (201) may be determined conveniently and precisely. In addition, the impact of the voltage at the cable joint (201) on the processing circuitry (103) can be reduced.
