摘要： The present invention relates a switch for a medium voltage or high voltage switchgear. The switch comprises: a first fixed contact; a second fixed contact; a moveable contact; a first gear wheel; and a second gear wheel. In an on state of the switch the moveable contact is in a position that connects the first fixed contact to the second fixed contact. In an off state of the switch the moveable contact is in a position where the first fixed contact is not connected to the second fixed contact. Rotation of the first gear wheel is configured to move the moveable contact. Rotation of the second gear wheel is configured to intermittently rotate the first gear wheel.

摘要： The present invention relates to a cooling apparatus for a medium voltage or high voltage switchgear, the cooling apparatus comprising: an evaporator section (2); a fluid conduit (3); a fluid phase separator (4); and a condenser section (5);
wherein, the evaporator section is configured to contact at least part of a current carrying contact;
wherein, the evaporator section is configured such that liquid fluid within the evaporator section can thermally contact an outer surface of the current carrying contact;
wherein, the evaporator section is fluidly connected to the fluid conduit;
wherein, the fluid conduit is fluidly connected to the condenser section;
wherein, the fluid phase separator comprises a part (4a) positioned within a portion of the fluid conduit adjoining the evaporator section;
wherein, the part of the fluid phase separator positioned within the portion of the fluid conduit adjoining the evaporator section comprises an open ended hollow tube-like shape, and wherein an outer surface of the tube-like shape is spaced from an inner surface of the fluid conduit to form a first channel and wherein the centre of the tube-like shape forms a second channel; and
wherein, the cooling apparatus is configured such that in use:
- the liquid fluid in the evaporator section is heated to a vapour state,
- the vapour is transferred from the evaporator section to the fluid conduit at least partially via the second channel,
- the vapour is transferred by the fluid conduit to the condenser section,
- the vapour in the condenser section is condensed to the liquid fluid, and
- the condensed liquid fluid is passively returned via the fluid conduit to the evaporator section at least partially via the first channel.

摘要： The invention relates to a cooling system for a medium voltage switchgear, the cooling system comprising:
- a conductor;
- a fluid conduit; and
- an insulator;
wherein, the conductor extends in a longitudinal axis; wherein, the conductor is configured to carry electrical current in the longitudinal axis direction;
wherein, a first part of the fluid conduit is located around an outer surface of the conductor and extends around the longitudinal axis;
wherein, a second part of the fluid conduit is connected to the first part of the fluid conduit and extends substantially perpendicularly to the longitudinal axis;
wherein, the insulator is located around the conductor at the position of the fluid conduit and covers the first part of the fluid conduit; and
wherein, the cooling system is configured such that a fluid can flow into the second part of the fluid conduit and from the second part of the fluid conduit into the first part of the fluid conduit.

摘要： The invention relates to a cable fixation element in low voltage compartments with an openable ring element, through which a number of cables can be aligned in parallel, wherein the cable fixation element has means, by which the cable fixation element can be fixed on a cable mounting board, according to claim 1. In order to to enhance the construction of such cable fixation element in low voltage compartments in such, that no additional space is needed to open the cable fixation elements, and that a high amount of parallel aligned cables can be fixed, the invention is, that the ring is openable in that way, that the physical opening direction is perpendicular to the long axis of the cables, which have to be placed in the fixation element.
