摘要： 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).

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： 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： A disconnector(100) and a switchgear(200) are provided. The disconnector(100) comprises a contact assembly(107) operable to change a status of a circuit, the disconnector(100) arranged in the circuit; shafts(101,102) adapted to be driven to rotate to operate the contact assembly(107); and a transmission unit(103) arranged between the shafts(101,102) and comprising: a plurality of gears(1031,1032) coupled to the shafts(101,102) to enable the shafts(101,102) to rotate with a mutual engagement of the plurality of gears(1031,1032); and a holding assembly(1033) adapted to hold radial positions of the plurality of gears(1031,1032) to ensure the mutual engagement of the plurality of gears(1031,1032). By arranging the holding assembly(1033) to hold the radial positions of the gears(1031,1032) to ensure the mutual engagement of the plurality of gears(1031,1032), only one input shaft(101) and one transmission unit(103) are enough to transmit large torques sufficient to operate the contact assembly(107), even in a case where the input and output shafts(101,102) are not coaxial. Accordingly, one sealing means is enough to well seal the disconnector(100). In this way, the complexity of assembly and costs are reduced.

摘要： Embodiments of present disclosure relate to a switchgear. The switchgear comprises: a cable compartment enclosed by walls and a cover; a cable connector arranged in the cable compartment and configured to electrically connect a cable to a cable bushing located in the cable compartment, wherein the cable connector comprises a first portion to which the cable is connected; and a metal plate arranged inside the cable compartment and comprising a main body arranged around the first portion; wherein a shortest distance between the main body and an outer surface of the first portion is in the range of 0 to 10 mm. This helps to reduce voltage drop across the plasma, resulting in a reduced energy of the arc. In this way, it is possible to minimize the undesirable results caused by the arc.
