摘要： The present invention relates to a system for monitoring a switchgear, the system comprising:
- an infrared camera;
- a processing unit; and
- an output unit.
The infrared camera is configured to acquire an infrared image of the switchgear. The processing unit is configured to convert the infrared image into a binary image. Pixels in the infrared image having a temperature equal to or above a first threshold value are given the same first value. Pixels in the infrared image having a temperature below the first threshold value are given the same second value. The processing unit is configured to implement a Siamese neural network to determine if a hot spot exists in the infrared image. The determination by the Siamese neural network comprises analysis by the Siamese neural network of the binary image and a reference binary image. The reference binary image was generated from a reference infrared image of the switchgear or of a reference switchgear. Pixels in the reference infrared image having a temperature equal to or above a second threshold value were given the same first value. Pixels in the reference infrared image having a temperature below the second threshold value were given the same second value to generate the reference binary image. The output unit is configured to output an indication of a fault in the switchgear on the basis that a hot spot has been determined to exist in the infrared image.-

摘要： The present invention relates to a medium voltage switchgear or control gear, comprising:
- at least one first compartment (1, 2, 4);
- a cable compartment (3, 10, 20);
- a plurality of main switchgear or control gear components; and
- a plurality of auxiliary switchgear or control gear components.
The plurality of main switchgear or control gear components comprises a main busbar system, a circuit breaker, and a first connector (31). The plurality of main switchgear or control gear components are configured to be housed in at least one part of the at least one first compartment. The plurality of auxiliary switchgear or control gear components comprises a medium voltage cable, and a second connector (30). The plurality of auxiliary switchgear or control gear components are configured to be housed in the cable compartment. The second connector is configured to connect to the first connector to connect the medium voltage cable in the cable compartment to a component (12) of the plurality of main switchgear or control gear components. Tthe cable compartment is configured to be disconnected from the at least one first compartment and wherein the cable compartment is configured to be spatially separated from the at least one first compartment, and wherein the disconnection of the cable compartment from the at least one first compartment comprises a disconnection of the first connector from the second connector. -
