摘要： The object of the invention is to create a device for ramming pole foundations which limits idle times between ramming operations. Rails (2) on which a self-propelled rail-road vehicle can be driven are laid on a ballast (1). The rail-road vehicle (3) can swivel over 360 DEG with its top (4) in relation to the undercarriage (5). An operation cabin (6), the counter-weight (7) and the hoisting arm (8) are arranged on the top (4). The turning and tilting unit (9) is provided at the free end of the hoisting arm (8). The leader (11) with the rammers (12) is mounted in a guiding unit (10). In the working position, the leader (11) stands vertically and the top (4) is turned over 90 DEG with respect to the direction of the rails. When the ramming operation is finished, the leader (11) is centrally clamped by the guiding unit (10) and is turned over 90 DEG by the turning and tilting unit (9). The leader (11) with the rammers (12) is then shouldered by the hoisting arm (8) and the device can thus be driven to the next ramming position.

摘要： The object of the invention is to create an arrangement for protecting the stator winding of a synchronous machine which dispenses with the need for a three-phase transformer for protecting the stator against accidental earthing. The exciting transformer (2) which feeds the exciting arrangement (3) is connected to the terminal of the synchronous machine (1) with its exciting winding (7). The displacement voltage is taken from the secondary side of the exciting transformer (2) by a single-phase low voltage transformer (4). A resistance (5) limits the current in the event of an accidental earthing of the stator. The displacement voltage is then imparted to the star point of the exciting transformer (2) by a single-phase transformer (6). In order to detect accidental earthings, the current that flows through the single-phase transformer (6) is measured by a relay (8) which then triggers a switching-off signal (9). The potential conditions in the exciting transformer and in the exciting arrangement connected thereto are not altered by these measures in relation to the conditions that reign when a separate transformer is provided to protect the stator against accidental earthing.

摘要： A circuitry for processing analogical current and voltage signals to be further processed by microcomputers (4, 5) has at least two input modules (1) for processing voltage signals and at least two input modules (2) for processing current signals. Among these modules, at least one input module (1, 2) of each type is coupled by two constant current sources (3) to two microcomputers (4, 5). Two detachable connections (6, 7) arranged at the output of each of the other input modules (1, 2) make it possible to connect at least one input module (1, 2) to both microcomputers (4, 5), via two constant current sources (3), or to connect at least one input module (1) for voltage signals to one microcomputer (4) and at least one input module (2) for current signals to the other microcomputer (5), each time via a constant current source (3). The number of inputs of both microcomputers (4, 5) is the same and always smaller than that of the input modules (1, 2). The number of constant current sources (3) corresponds to the sum of the inputs of both microcomputers (4, 5). The advantage of this circuitry lies in the possibility to match the fixed and variable input modules (1, 2) so that the greatest possible freedom is ensured at the design stage with a minimal amount of hardware.

摘要： The object of the invention is a low-part-load and mechanically reliable fixing for a high-voltage winding which can also be easily manufactured. The winding is fixed in the region of its head with a glass-fibre tube (1) passing around each winding rod (2). The glass-fibre tube is surrounded by a woven glass or polyester structure. In order to obtain good mechanical strength the glass-fibre tubes (1) are filled with a resin. In order to prevent partial discharges in the interstices (4) formed by the glass-fibre tube (1) and the rod or winding insulation (3), the glass-fibre tube is coated with a semiconducting polymer. The purpose of the elastic polymer coating is to provide a seal when resin is injected into the woven glass tube. In addition, the entire potential distribution between the two conductors and coil or rod insulation is shifted in favour of the glass tube, thus preventing the ionisation of the interstices.

摘要： A filter arrangement is useful for filtering and damping harmonics and for shifting resonance points in electric networks. To this end, a first energy-absorbing damping element (Rp21) is connected in parallel with a series arrangement consisting of a first inductance (Lp2), a first capacitance (Cp21) and a fourth capacitance (Cp22). This parallel arrangement is connected in series with a parallel path consisting of a second inductance (Lp3) and a second capacitance (Cp3), as well as with a third capacitance (C1). In addition, a second energy-absorbing damping element (Rp41) is connected in parallel with the series arrangement consisting of the fourth capacitance (Cp22) and the second capacitance (Cp3). The use of this filter arrangement in the case of two tuning frequencies permits strong damping of harmonic currents with frequencies close to one of the two tuning frequencies, without significant losses due to currents with the operating frequency.

摘要： In a stator earth leakage detection process, clear differences in the third harmonic in the faultless and in the earth leaking state may be ascertained but the parasitic current is nevertheless shunted and the vibrations is dampened. For that purpose, a three-phase current transformer (2) is connected to the terminals of a three-phase current machine (1), for example a synchronous generator. The three-phase current transformer (2) must have a free magnetic short-circuit in order to transmit a null voltage in the event of an earth leakage of the three-phase current motor (1). The primary winding of the transformer (2) is star connected with an earthed star point. The secondary winding of the transformer (2) is connected so as to form an open triangle and is loaded with the resistance (4) which may be switched off by the switch (5) connected in series. A voltage converter (6) is connected to the earthed star point of the three-phase current machine (1). The secondary voltage of said converter (6) and the voltage at the open triangle winding are supplied to a static earth leakage relay (7) that detects an earth leakage in the generator (1) on the basis of the amplitude and phase position of the third harmonic in said voltages.

摘要： A combined gas-steam turbine power station has a gas turbine installation (1) and a steam turbine (5) connected with a generator (24). The combustion gases from the gas turbine (1) are heated in an additional firing place (2) and then flow through at least two evaporators (3, 4), the first of which has an overheater. In addition, a closed steam circuit is provided, in which the evaporator (3) with the overheater followed by the steam turbine (5) is located, as well as a heater (6) for a double-circuit heater (8) preferably provided for heating a long-distance energy medium (7). The second heater (9) of the double-circuit heater (8) is arranged in a closed heat pump circuit (10) in which the second evaporator (4), a steam compressor (12) driven by a motor (11) and a valve (13) are located. The long-distance energy medium (7) flows at first through the heater (9) in the heat pump circuit (10), then through the heater in the steam circuit. Thanks to the heating of the long-distance energy medium by the steam circuit and heat pump, more than 80 % overall efficiency is achieved. In addition, the outlet temperature of the gas turbine combustion gases is very low (90 DEG ), so that their thermal utilization coefficient is very high.

摘要： The aim of the invention is to obtain a transformer in which loosening of the winding due to dynamic short-circuit forces is prevented. The transformer has a pressure beam (1) which yokes the windings (2), which are terminated by the winding pressure ring (3). The expanding spring element (6) is arranged between the pressure beam and the winding ring (3). The spring element (6) consists of the bushing (7), the springs, in particular superimposed cup springs (8), and the plunger (9). Adjusting screws (10) which act on the plunger (9) are seated in the pressure beam (1). The necessary preliminary pressure is applied to the plunger (9) by a hydraulic cylinder (11) which is inserted through a bore (15) in the supporting surface (4) of the pressure beam (1). After the cup springs (8) are fastened by the plunger (9), which in turn is held by the adjusting screws (10), the hydraulic cylinder (11) can be removed. This invention makes it possible for the first time to maintain the winding pressing required for reliable operation of the transformer throughout the entire service life of the transformer, and this spring element (6) possesses a certain flexibility.
