A High-Voltage Direct Current (HVDC) disconnector comprising:
- a fixed contact comprising a guide and at least a first and second conducting member positioned in the guide wherein the first and second conducting members are both tulip contacts;
- a movable contact comprising a first mobile arm and a second mobile arm having a conducting element, wherein the second mobile arm is movable from an open position to a closed position to close a connection between the fixed contact and the second contact;
- and
- a slider movably supported on the second mobile arm, the slider being movable between a first position wherein a contact surface of the conducting element is covered and a second position wherein the contact surface is exposed for contact with the first and second conducting members.
A method of closing a connection in a HVDC disconnector, the method comprising:
- actuating a movable contact having a first mobile arm and a second mobile arm having a conducting element so as to move the second mobile arm from an open position to a closed position in a fixed contact comprising a guide and at least a first and second conducting member disposed in the guide wherein the first and second conducting members are both tulip contacts;
- and
- moving a slider movably supported on the second mobile arm from a first position wherein a contact surface of the conducting element is covered to a second position wherein the contact surface is exposed for contact with the first and second conducting members.
