摘要： The present invention relates to a three-position disconnector switch, comprising: a power in contact (1); a piston (2); a power out contact (4); a plurality of flexible locking elements (5); an earthing contact (6); and a threaded rod (7). A length of the piston is such that in a first switch position an outer surface of a wall of the piston makes an electrical contact between the power in contact and the power out contact. The length of the piston is such that in a second switch position the outer surface of the wall of the piston does not make an electrical contact with either the earthing contact or the power in contact, and wherein in the second switch position the outer surface of the wall of the piston makes an electrical contact with the power out contact. The length of the piston is such that in a third switch position the outer surface of wall of the piston makes an electrical contact between the earthing contact and the power out contact. The piston comprises an inner threaded section configured to engage with the threaded rod, and wherein rotation of the threaded rod is configured to engage with the inner threaded section to move the piston along an axis of the switch between the different switch positions. The piston comprises a groove extending in a direction parallel to the axis. Each of the flexible locking elements is configured such that a part of each of the flexible locking elements moves into and out of the groove as the piston is moved along the axis of the switch between the different switch positions as the piston is moved in both directions along the axis. As the piston is moved along the axis the switch is configured such that there is always a part of at least one flexible locking element in the groove. When a part of at least one flexible locking element is in the groove the piston is constrained from rotating about the axis.

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 a first infrared image of the switchgear, wherein a total number of pixels in the first infrared image is equal to a first number. The processing unit is configured to determine a pixel in the first infrared image with a maximum temperature in the first infrared image. The processing unit is configured to utilize a second number less than the first number to determine a temperature interval for the first infrared image equal to a difference between the maximum temperature in the first infrared image and a threshold temperature in the first infrared image. The processing unit is configured to determine the threshold temperature in the first infrared image as a pixel temperature in the first infrared image that results in a number of pixels in the first infrared image having a temperature between the threshold temperature in the first infrared image and the maximum temperature in the first infrared image that most closely matches the second number. The processing unit is configured to determine that a hot spot exists in the switchgear. The determination that the hot spot exists comprises utilization of the temperature interval for the first infrared image. The output unit is configured to output an indication of a fault in the switchgear when the determination has been made that a hot spot exists in the switchgear.-

摘要： The present invention relates to a three-position disconnector switch, comprising: a platform (1); a power in contact (3); a power out contact (4); an earthing contact (5); and a piston (6). In a first switch position the piston makes an electrical contact between the power out contact and the power in contact. In a second switch position the piston makes an electrical contact with the power out contact. In a third switch position the piston makes an electrical contact between the power out contact and the earthing contact. The piston is configured to move along an axis of the three-position disconnector switch to transition the three-position disconnector switch between the different switch positions. The power in contact is mounted to the platform, the power out contact is mounted to the platform, and the earthing contact is mounted to the platform.

摘要： The present invention relates to a three-position disconnector switch, comprising:an earthing contact (1); a power out contact (2); a power in contact (3); and a piston (4). The power out contact comprises a first part (2a) and a second part (2b), and wherein the first part is connected to the second part by a leg portion (2c). In a first switch position an outer surface of a wall of the piston makes a direct electrical contact with the first part of the power out contact and makes a direct electrical contact with the power in contact. In a second switch position the outer surface of the wall of the piston makes a direct electrical contact with the first part of the power out contact and makes a direct electrical contact with the second part of the power out contact. In a third switch position the outer surface of wall of the piston makes a direct electrical contact with the second part of the power out contact and makes a direct electrical contact with the earthing contact. The piston is configured to move along an axis of the three-position disconnector switch to transition the three-position disconnector switch between the different switch positions

摘要： The invention relates to a power distribution equipment personnel safety system, comprising: a power distribution equipment (1); a processing unit (3); at least one vicinity sensor (4); and at least one power distribution equipment sensor (5). The power distribution equipment comprises an outer envelope, and wherein the outer envelope comprises at least one door configured to permit access to an interior of the power distribution equipment and/or wherein the outer envelope comprises at least one cover configured to permit access to the interior of the power distribution equipment. The at least one vicinity sensor is configured to acquire vicinity sensor data in an area outside of the outer envelope of the power distribution equipment, and provide the vicinity sensor data to the processing unit. The processing unit is configured to determine a position of a person in the area outside of the outer envelope of the power distribution equipment, the determination comprising utilization of the vicinity sensor data. The at least one power distribution equipment sensor is configured to acquire status data of the outer envelope of the power distribution equipment and provide the status data to the processing unit. The processing unit is configured to utilize the status data to determine whether the power distribution equipment outer envelope is undisturbed where the at least one door and/or the at least one cover are correctly closed or whether the outer envelope is disturbed where one or more doors or one or more covers are open or not correctly closed or one or more covers are removed. The processing unit is configured to determine a personnel safety state, the determination comprising utilization of the position of the person in the area outside of the outer envelope of the power distribution equipment and whether the power distribution equipment outer envelope is undisturbed or whether the outer envelope is disturbed.
