摘要： A disconnector for electrical disconnection or isolation is provided. The disconnector comprises a switch and an actuating mechanism. The switch comprises a first, fixed, contact terminal of a first conductor, a second, fixed, contact terminal of a second conductor, and a moveable bridge contact moveable between a first position and a second position. The actuating mechanism comprises: a cam follower comprising a following surface; an urging member comprising a cam surface, wherein the urging member is rotatable around an axial direction relative to the cam follower, and wherein at least one of the following surface and the cam surface comprises an angled portion, the angled portion angled with respect to the axial direction such that rotation of the urging member urges the cam follower in the axial direction, wherein the cam follower is configured to move the moveable bridge contact from the first position to the second position in response to the urging; and a biasing member configured to exert a force on the moveable bridge contact to oppose the movement of the moveable bridge contact in the axial direction.

摘要： A switch disconnector with current detection is provided. The disconnector comprises a switch, the switch comprising: a first, fixed, contact terminal of a first conductor, a second, fixed, contact terminal of a second conductor, and a moveable bridge contact. An actuating mechanism of the disconnector is configured to open and close the switch by actuation of the moveable bridge contact, wherein the actuating mechanism is configured to move the bridge contact in a direction from a first position to a second position, wherein in the first position the switch is closed and the bridge contact is in electrical contact with the first and second contact terminals to define a current conduction path, and wherein in the second position the switch is open and the bridge contact is electrically separate from the first and second contact terminals. The disconnector comprises a detection coil disposed around the first contact terminal or the second contact terminal of the switch, the detection coil configured to output a signal indicative of a current through the respective contact terminal. The disconnector also comprises a communication module communicatively coupled to the detection coil and configured to receive the signal indicative of a current through the respective contact terminal and provide an output signal in dependence on the received signal.
