Title:
WIRELESS SENSING SYSTEM AND METHOD FOR SWITCHGEAR
Document Type and Number:
WIPO Patent Application WO/2019/157622
Kind Code:
A1
Abstract:
A wireless sensing system (150) for a switchgear (100), the system (150) comprises a set of one or more wireless sensors (202) provided in a first compartment (104) of the switchgear (100) and mounted to a fix contact (112) of a circuit breaker (110) in the switchgear (100) by a sensor holder (402), wherein the circuit breaker (110) is provided in the first compartment (104), the set of one or more wireless sensors (202) is configured to sense a temperature of the fix contact (112) to generate a sensor signal representing the temperature, and the sensor holder (402) is adapted to fix the set of one or more wireless sensors (202) between the fix contact (112) and the sensor holder (402). The system (150) comprises a further set of one or more wireless sensors (600,600',600'') provided in the first compartment (104) and configured to sense a current of the circuit breaker (110) to generate a further sensor signal representing the current. The system (150) comprises an antenna (114) provided in the first compartment (104) and configured to receive the sensor signals from the wireless sensors (202,600,600',600'').
