Title:
APPARATUS FOR MEASURING TEMPERATURE OF SWITCHGEAR AND SWITCHGEAR
Document Type and Number:
WIPO Patent Application WO/2022/133779
Kind Code:
A1
Abstract:
A switchgear (200) and an apparatus for measuring temperature of the switchgear (200). The switchgear (200) comprises a busbar compartment (202) and a circuit breaker compartment (203), and the apparatus comprises at least one sensor (101) arranged at a busbar (201) in the busbar compartment (202) and adapted to sense a temperature of at least one predetermined position of the busbar (201); a transmission module (102) coupled to the at least one sensor (101) and adapted to transmit data representing the temperature of the at least one predetermined position; and a power module (103) adapted to power the at least one sensor (101) and the transmission module (102), wherein at least one of the transmission module (102) and the power module (103) is detachably arranged at an interface (204) between the circuit breaker compartment (203) and the busbar compartment (202). With the transmission module (102) and/or the power module (103) detachably arranged at the interface (204) between the circuit breaker compartment (203) and the busbar compartment (202), the transmission module (102) and/or the power module (103) may be separately replaced. In this way, replacement efficiency is significantly improved and maintenance costs are reduced. Furthermore, the interface (204) where the transmission module (102) and/or the power module (103) is arranged allows the replacement of the transmission module (102) and/or the power module (103) without powering off the entire busbar (201), which improves reliability of the switchgear (200).
