摘要： A rotor shaft adapted to rotate about a rotor axis thereof. The rotor shaft includes a rotor cavity configured concentrically to the rotor axis inside the rotor shaft. The rotor shaft further includes a plurality of cooling bores extending radially outward from the rotor cavity to feed cooling air into an internal cooling system in a blade. Each cooling bore includes a bore inlet portion and a distal bore outlet portion. The respective bore inlet portion ends in a plateau, projecting above the outer circumference contour of the rotor cavity. Thus, cooling bore inlets are shifted to a low stress area and the lifetime of the rotor is improved.

摘要： A method for measuring a concentration of dibasic acid in a cleaning process substance is provided. The method includes sending a plurality of voltage pulses through the cleaning process substance by each a first electrode and a second electrode. Each the first electrode and the second electrode is in contact with the cleaning process substance containing a concentration of dibasic acid. The method also includes receiving current responses generated by the plurality of voltage pulses, and analyzing the current responses using a multivariate data analysis for calculation of the concentration of dibasic acid in the cleaning process substance. A dibasic acid sensor, a control unit, and an analyzing unit for performing the method, are also provided.

摘要： A method of recognizing partial discharges emitted inside or outside electrical equipment after at least one partial discharge activity has been detected Partial discharge patterns are recorded beforehand in a data base, each pattern being associated with the type of fault that generated it. A new partial discharge (Pd) pattern is acquired. The new partial discharge pattern is compared with discharge patterns that are already recorded in the data base The matching fault in the equipment is obtained by deduction, and the result is recorded in the data base.

摘要： The invention refers to a method for selective laser melting additive manufacturing a three-dimensional metallic or ceramic article/component entirely or partly. The method includes successively building up said article/component layer by layer directly from a powder bed of a metallic or ceramic base material by means of remelting the layers with a high energy laser beam, moving repetitively across the areas, which are to be solidified. The movement of the laser beam is made of a superposition of a continuous linear movement and at least one superimposed oscillation with a determined frequency and amplitude. The oscillation is created by a beam deflection device and the same beam deflection device is also used for linear positioning movement.

摘要： A flow control device is used to regulate fluid flow from an upstream supply source to a downstream destination within a plant. At least portions of the flow control device are fabricated from one or more thermostatic materials selected based on the specific thermostatic properties thereof. The basic arrangement of the flow control device includes at least one housing with at least one thermostatic beam and at least one wall fixed thereto to define a void interior area with opposed open ends, and a center plug member with at least one opening in at least one wall thereof arranged within the interior area for temperature dependent fluid flow therethrough.

摘要： Systems and methods according to these exemplary embodiments provide for methods and systems related to optical current sensors used to monitor standby power transformers, specifically fiber optical current and voltage sensors and, more particularly, to applications involving filters for use in such sensors, such as frequency tracking comb filters. According to one embodiment, a method for monitoring a connection condition of a stand by power transformer includes the steps of measuring a current flowing through a high voltage side of the standby power transformer using at least one optical current sensor disposed proximate to a current flow path of the high voltage side, using a comb filter to filter the measured current, determining whether the filtered, measured current is less than a predetermined threshold value; and generating an alarm indication that the high voltage side of the standby power transformer is unconnected.

摘要： Device for making and/or breaking a current including a pair of permanent contacts (3, 4), at least one of the contacts (3, 4) being movable. At least one permanent contact (3, 4) including a main portion (3.1, 4.1) having a free end and an end protection portion (3.2, 4.2) secured to the free end of the main portion (3.1, 4.1), designed to be in mechanical and electrical contact with the other permanent contact (4, 3) only during an operation for opening or closing the pair. The end protection portion (3.2, 4.2) is made of a single transition metal having a melting temperature that is strictly higher than that of the main portion (3.1, 4.1) to which it is secured, or of an oxide or carbide of such a metal, or even of zinc oxide. For application in particular to high- or medium-voltage circuit breakers.
