Abstract: A control unit having a connection structure for connecting components of the control unit to a base plate which eliminates the need for separate fasteners. The control unit includes circuitry mounted to a PCB, and the PCB is pre-assembled to a base plate, to form a pre-assembly. During assembly, the PCB and the base plate are aligned when placed in a tooling device which clamps and holds the pre-assembly in place during the over molding process. The circuitry is over molded with an epoxy material, such that the epoxy material flows from a top side of the PCB to underneath the base plate, and the PCB is fixed to the base plate without the use of fasteners such as screws, or adhesive materials.

Abstract: A control unit having a connection structure for connecting components of the control unit to a base plate which is cost effective, and facilitates heat transfer from a printed circuit board (PCB) to the base plate. The control unit includes circuitry mounted to a PCB, and the PCB is mounted to a base plate. The circuitry is over molded with epoxy material during manufacturing. The epoxy material flows between the PCB and the base plate, such that a layer of the epoxy is disposed between the PCB and the base plate. This layer of epoxy functions as a heat transfer layer, and a connection structure to connect the PCB to the base plate. The epoxy material transfers heat from the surface of the PCB in contact with the layer of epoxy to the surface of the base plate in contact with the layer of epoxy.

Abstract: A rotation device including first and second passages and a rotor shaft with a rotor which connects onto the first passage with a third passage which branches into rotor channels from the third to a fourth passage. The end zones of the third and fourth passages extend axially. The rotation device has a stator including a first central body with an outer surface which co-bounds a passage space with stator blades which have on one end zone forming a fifth passage a direction differing from the axial direction and on another end zone forming a sixth passage a direction differing little from the axial direction. The fifth passage connects onto the fourth passage and the sixth passage connects onto the second passage. The stator includes a second central body where between the sixth passage and the second passage extend manifold channels bounded by the second central body and the housing.

Abstract: For precise measurement of currents with high dynamic range, especially in gas-insulated voltage switchgear, a first signal of a first low-power measurement transformer and a second signal of a second nonmagnetic measurement transformer, operating, for example, according to the principle of a Rogowski coil or according to the Faraday effect, are compared. Depending on the degree of accuracy, one of the two signals is then selected and further processed. A deviation of the two signals from each other, especially their gradient, is referred to as comparison criterion. In a corresponding configuration, the two measurement transformers of different type are connected to a common processing component for signal processing.
