摘要： A effective lower flow direction comprises power module (3) and a housing (2) that is arranged on an upper surface (9) of the power module (3) defining an upper flow section (10) for liquid cooling of the power module (3) in between. The upper flow section (10) comprises an inlet (12), an outlet (13) and a given upper flow path (15) in between defining an effective upper flow direction (11). Further, a cooling unit (5) is arranged on the lower surface (9) of the power module (3) defining a lower flow section (20) for liquid cooling of the power module (3) in between. The lower flow section (20) comprises an inlet (22), an outlet (23) and a given lower flow path (25) in between defining an effective lower flow direction (21), such that during operation a coolant flows through the upper and the lower flow section (10, 20) providing a double-sided liquid cooling of the power module (3). The effective upper flow direction (11) is different from the effective lower flow direction (21), and the inlet (12) of the upper flow section (10) and the outlet (23) of the lower flow section (20) are fluidically connected with each other.

摘要： According to an embodiment, the method for estimating an environmental impact caused by a technical process comprises a step of providing input information (Ii) which is representative for a predefined technical process (Pi), said predefined technical process comprising one or more predefined process steps (Sij). In a further step, reference information (Ir) is provided which is representative for different known process steps (Srj) and representative for the environmental impact caused by each known process step. In a further step, output information (Io) is determined depending on the input information and the reference information. The output information is representative for at least a portion of an estimated environmental impact caused by the predefined technical process

摘要： A transformer assembly (1) for electric grids comprising:
- an electric transformer (2) comprising a magnetic core (20), a first side (2A) including one or more first windings (21) enchained with said magnetic core and adapted to be electrically connected to a first grid section (50) and a second side (2B) including one or more second windings (22) enchained with said magnetic core and adapted to be electrically connected to a second grid section (60);
- a tap changer (3) operatively associated with said electric transformer (2) to vary the number of turns enchained with said magnetic core (20) for said first windings (21) or for said second windings (22).
The transformer assembly comprises a control unit (6) operatively coupled with said tap changer (3) to control the operation of said tap changer, said control unit being configured to:
- acquire input data (IN) indicative of an electrical connectivity condition of said second grid section (60) with said second windings (22);
- basing on said input signals (IN), determine whether said transformer (2) is in a load condition or in a no-load condition;
- if said transformer (2) is in a no-load condition, command said tap changer to set a maximum available number of turns for said first windings (21) or for said second windings (22).-

摘要： An aspect of the present disclosure provides a method for measuring a quantity of liquid in a liquid-insulated electrical component. The liquid-insulated electrical component includes a main tank (1) and an expansion tank (2) fluidly connected to the main tank (1). The method includes measuring a first pressure (P 1 ) at a first point in the main tank (1), measuring a second pressure (P 2 ) at a second point in the main tank (1), the second point being at a height (H) above the first point, measuring a third pressure (P 3 ) at a third point in the expansion tank (2), and determining the quantity of liquid in the liquid-insulated electrical component based on the first pressure (P 1 ), the second pressure (P 2 ) and the third pressure (P 3 ). Further aspects provide a liquid-insulated electrical component, particularly a transformer, more particularly a traction transformer (101) for a railroad vehicle (100), as well as a railroad vehicle (100) including said liquid-insulated electrical component.

摘要： According to an embodiment, the spacer element (1) for a winding (100) of an electric device comprises at least one connection member (20, 21, 22) and a plurality of ribs (3). The ribs are connected to the connection member and are spaced from each other pairwise. The spacer element is arrangeable between two successive winding units (10) of the winding during manufacturing of the winding. Each two adjacent ribs delimit a flow channel (4) for a cooling fluid, said flow channel extends between and along the two adjacent ribs.
