摘要： The invention relates to a step switch with a selector for continuous switching between different winding tappings of a tapped transformer. The entire selector is configured as a separate component group and housed in a separate housing made of an insulating material. The fixed selector contacts are configured in a circular manner and arranged around a switch stick in different planes in the interior of the insulating cylinder. They are switched by selector contact bridges which have radially elastic contact elements and are fixed to the switch stick.

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： Solid-state circuit breakers (SSCBs) have been witnessing an impressive progress with the aid of wide bandgap (WBG) devices such as silicon carbide (SiC) MOSFETs. Along with obtaining high efficiency as the result of low on-state resistance, response times have been gaining remarkable achievements in microseconds range. Not only that, the reported successes in control and gate drivers design and incorporating fault detection/location techniques in SSCBs are promising. A MOV- resistive capacitive switch (MOV-RCS) snubber for solid state circuit breakers addresses the following: 1) the MOV degradation issue in DCCBs is solved, 2) the maximum allowable DC bus voltage on DCCBs is extended. The solid state circuit breaker and an active clamping snubber includes a first circuit including a fault current bypass based solid state breaker for low voltage direct current systems.
