Abstract

The invention relates to a method (1) for determining the operating state of a transformer (9) located in a high-voltage network, said transformer comprising: a tank (11) filled with insulating liquid; an active part that is located in the tank (11) and has windings that enclose a core and sections of the core; and a cooling unit for cooling the insulating liquid. In the method according to the invention: - measurement values are obtained from sensors which are located in or on the power transformer, wherein said measurement values are used to obtain at least one liquid temperature measurement value (?Tao,meas, Do,meas) which corresponds to a measurement temperature of the insulating liquid or is calculated from a plurality of temperature values (Tamb), and wherein at least one temperature value corresponds to a measurement temperature of the insulating liquid (Ttop, Tbot); - the measurement values and/or values derived therefrom are supplied to a thermohydraulic simulation model (4); - the thermohydraulic simulation model (4) then determines the operating state of the transformer (9) by providing, on the output side, simulated state parameters which together represent the operating state of the transformer, wherein at least one state parameter is an insulating liquid temperature state parameter which corresponds to a temperature value simulated for the insulating liquid. In such a method, it ought to become possible to take weather influences such as wind or rain into account. Therefore, according to the invention at least one controlled system (3, 4) is connected upstream of the thermohydraulic simulation model (4) on the input side, which controlled system determines a control deviation (eAO, eO) which is formed from the difference between the liquid temperature measurement value (?Ta o ,meas, Do,meas) and the corresponding simulated insulating liquid temperature state parameter (?Tao, Do).

A device for adjusting a feed water mass flow has a set point for the feed water mass flow. During the creation of the set point for the feed water mass flow, a waste-heat flow transferred to a fluid in the evaporator heating surfaces is determined, and mass storage and energy storage in the fluid in the evaporator heating surfaces is detected during non-steady- state plant operation. A behaviour over time of a mass storage in the evaporator is coupled with a behaviour over time of a mass storage in the pre-heater, wherein scaling is carried out with a ratio of the density changes in the evaporator and pre- heater.

Abstract

A glass ring for current measurements includes a glass body, which can be disposed around an electrical conductor and has a light entry surface and a light exit surface. The glass ring allows light which enters the glass body through the light entry surface to circulate completely around the conductor in the glass body by reflection on external sides or outer faces of the glass body, the light exiting from the glass body on the light exit surface. The glass ring is formed of a monolithic glass body. A method for optical current measurement includes using a current flow in an electrical conductor to generate an electromagnetic field around the conductor, by which a polarization of a light beam in the glass ring around the conductor, in particular with a plane perpendicular to the longitudinal axis of the conductor, is changed as the light beam circulates around the conductor.

Abstract

A device for reactive power compensation in a high-voltage network contains a phase conductor. A high-voltage connection is provided for each phase of the high-voltage network. Each high-voltage connection is connected to a first high-voltage winding which surrounds a first core portion and to a second high-voltage winding which surrounds the second core portion. The core portions are part of a closed magnetic circuit. The low-voltage ends of each high-voltage winding can be connected to at least one saturation switching branch configured to saturate the core portions and has actuatable power semiconductor switches controlled by a control unit. To manufacture the device inexpensively, each saturation switching branch has a two-pole submodule having a bridge circuit and a DC voltage source so that, depending on the actuation of the power semiconductor switches, the DC voltage source can either be connected in series to the high-voltage winding or can be bridged.

Abstract

In some embodiments, a connection bar is provided for connecting multiple high voltage coils of a dry-type transformer along a top or bottom of the dry-type transformer. The connection bar includes (1) an electrically insulating body having a plurality of openings, each opening sized to receive at least one of high voltage terminals of the transformer; (2) an electrical connection pathway within the electrically insulating body configured to create a predetermined electrical connection between multiple high voltage coils of the transformer; (3) external connector terminals embedded within and extending from the electrically insulating body, the external connector terminals connected to the electrical connection pathway; and (4) a ground shield embedded within the electrically insulating body and configured to shield high voltage terminals of each high voltage coil of the transformer. Numerous other aspects are provided.

Abstract

The invention relates to a core for a transformer. Said core comprises a multiplicity of bent metal sheets bonded together to form a structure surrounding a core opening and forming the core. Said metal sheets comprise sheet ends not touching one another within the core, causing the core with said metal sheets to form at least one air gap at said sheet ends within the core or at a periphery of the core. Said air gap forms magnetic resistance that increases with the width of said air gap. This causes no-load losses. An object of the invention is to minimize those no-load losses in the transformers through the lowest possible magnetic resistances. A lacquer is provided which contains magnetic particles. Said lacquer impregnates or coats the core at least at said sheet ends of said metal sheets and fills each air gap between said sheet ends of said metal sheets.
