Abstract:
A drive rod for a switch (11) for high-voltage or medium-voltage installations, having a drive mechanism (16) for opening or closing the switch. The drive rod (10) comprises a first, electrically insulating material and in operation is connected to a moving contact (14) of a vacuum circuit (11) at one end and to the drive mechanism (16) at an opposite end. One end of the drive rod (10) can be coupled to the drive mechanism (16) by means of a securing body (20), the securing body (20) comprising at least one region which is provided with a plurality of projections (23), which projections (23), in operation, engage in the end of the drive rod (10).
Abstract:
Disconnector for switchgear, having a first contact position, in which an electrical contact is provided between a main terminal and a first terminal, and a second contact position, in which an electrical contact is provided between the main terminal and a second terminal, the disconnector comprising a connector body which is moveable in a first direction between the first and second position and provided with an end portion which is extendable in a direction substantially perpendicular to the first direction for providing a contact force between the end portion and the first, second or main terminal, a first operating mechanism which is arranged to move the connector body between the first and second position, and a second operating mechanism which is arranged to extend the end portion of the connector body when the disconnector is in either the first or second contact position, in which the end portion of the connector body is provided with a conical inside surface and the second operating mechanism comprises a first shaft provided with a first conically shaped end body positioned inside the conical inside surface of the end portion of the connector body.
Abstract:
Drive mechanism for the synchronous operation of a plurality of vacuum circuit breakers (35). It comprises energy storage means (6), conversion means (37) for converting energy stored in the energy storage means (6) into an operation of switching off the vacuum circuit breakers (35) and for switching on the vacuum circuit breakers (35), in which latter process energy is simultaneously stored in the energy storage means (6). The conversion means (37) comprise first transfer means which can move substantially in a first direction and second transfer means which can move substantially in a second direction. The conversion means also comprise at least one connecting rod (4, 4'), which on one side (23, 23') is rotatably secured to the first transfer means and on a second side (22, 22') is rotatably secured to the second transfer means. The drive mechanism also comprises a trip mechanism which interacts with the drive mechanism and a disconnector drive mechanism (70) for the simultaneous operation of disconnectors (73).
