Definitions

  • the invention relates to a filled with an insulating liquid tap changer and means for receiving the thermally induced volume fluctuations of this insulating liquid.
  • the invention enables a hermetic closure of the switch vessel and thus a significant reduction in the aging of the switch oil.
  • the use of the arrangement according to the invention also makes it possible to dispense with dehumidifier, external expansion vessel and associated piping. Furthermore, the invention solves the problem of gas accumulation in the pipeline to the expansion vessel of hermetically sealed switches.
  • Tap changers of the type mentioned above are mainly used in power transformers for regulating the voltage under load. In operation, it comes through heating of the switching resistors, heat dissipation by the surrounding the switch and its vessel insulating and cooling medium of the transformer and other influences to significant temperature fluctuations. These cause significant changes in the volume of the insulating liquid of the tap changer. Furthermore, switching arcs and / or heating of the switching resistors cause the thermal decomposition of insulating liquid and resulting gas evolution. These gases rise due to their lower density and must be removed by appropriate measures.
  • the state of the art is the use of expansion vessels mounted above the transformer, which are connected to the switch via an inclined pipeline. Through this pipeline, both the flow of the insulating liquid at thermally induced volume changes, as well as the removal of the gases.
  • WO98 / 54498 is a cover for pressure relief valves known and in DE 10312177 the integration of a cover into a pressure relief valve is described. Both solutions are associated with considerable handling problems and require a large amount of space.
  • the invention described below enables a compensation of the change in the volume of the insulating liquid during operation of the switch, while avoiding the above-mentioned disadvantages.
  • the present invention uses a bellows / compensator to absorb the thermally induced volume fluctuations of the insulating liquid of the switch.
  • Such arrangements are already off GB425169 and JP03192707 known.
  • This balancing device forms a compact assembly without additional piping and is mounted directly on the switch.
  • the shape of the expansion vessel is largely adapted to the contour of the tap changer head, so that the space requirement is kept small.
  • the expansion tank thus forms a unit with the switch and remains attached during transport. The cumbersome installation of expansion vessel and pipes in the installation of the transformer omitted.
  • this pot is formed so that a cavity is created, which can be used to accommodate or accommodate the necessary protection and monitoring technology.
  • this pot is designed such that it serves as a cover and protective cover for the protection, monitoring and control devices.
  • the design of the pot is provided as a cover and splash guard for a pressure relief valve. The pot takes over the collection and the discharge of the hot oil surge in case of failure.
  • the compensation body becomes part of the switch. Additional external assemblies are eliminated and simplify the entire transformer. Problems with gas accumulation in pipelines and obstruction of the oil flow with temperature changes of the insulating liquid are excluded by the elimination of the problems associated with these assemblies. Due to the inventive design of the volume compensation device can be a complete completion of the insulating liquid of the switch from the atmosphere / ambient air reach. The absorption of moisture and oxygen by the insulating liquid is prevented. An influence of the electr. Damping strength of the insulating liquid by moisture is avoided and the aging of the insulating significantly reduced. The outer expansion tank, the dehumidifier and the associated piping can be omitted. Regular checking of the condition The drying agent in the dehumidifier can be saved and it comes to cost savings by eliminating the costly regular replacement of the drying agent. Pollution and disposal problems caused by spent desiccants are avoided.
  • the switch is equipped with a gas release valve (V3).
  • V3 gas release valve
  • This may conveniently be carried out or controlled so that it responds to a small gas pressure, but not in case of insulating liquid.
  • This is advantageously realized by the control of the gas outlet valve by means of a float (SW).
  • SW float
  • D1 large-area pressure relief valve
  • D1 the bellows enclosing the pressure relief valve.
  • this design also allows leakage monitoring.
  • a guide tube By using a guide tube, the bellows of the compensator can be protected against lateral deflection (kinking). This guide tube can also be used to accommodate the occurring during transport of the transformer lateral acceleration forces.
  • the Druckwellenleit adopted for the pressure relief valve is used as a guide tube for the bellows.
  • the Druckwellenleit adopted is designed such that a secure transmission of the pressure waves is ensured both with stretched compensator and with a compressed compensator.
  • Moving basic element of the compensator is the metal bellows, which has an axial mobility due to its annular circumferential waves, which in use used in the expansion vessel according to the invention to compensate for the thermally induced volume changes of the insulating liquid of the tap changer.
  • This bellows draws its flexibility from the flexibility of the radial standing flanks. It is preferable for the described application, the lyre-shaped shaft due to the great flexibility with sufficient compressive strength.
  • the compensating body is provided with a spring element in order to achieve a predetermined pressure play.
  • spring elements can also be formed by the body of the compensator itself.
  • the compensating device is equipped with a volume limitation in one or both directions.
  • a volume limitation in one or both directions.
  • This limitation is also possible by a stroke limitation of the compensation elements and a multi-part compensating device with chambers of different spring constant.
  • FIG. 1 shows a switch (S) with a switch head (SK), which is arranged on the cover of a transformer.
  • the space inside the switch (S) is filled with insulating liquid. Since the housing of the switch (S) hermetically seals this, it comes when heating the insulating liquid of the switch to an increase in the internal pressure in the switch. This pressure increase causes an expansion of the compensator (K). Gases forming by thermal decomposition of oil rise upward and are guided through the cylindrical pipe sections (R1) to a monitoring device (D1). One of the two pipe segments (R1) is arranged on the movable end plate of the compensator. These pieces of pipe are designed so that they ensure a safe derivation of pressure waves to the pressure relief valve (D1) at each position of the compensator.
  • the height is dimensioned such that the compensator exploits its full flexibility and a safe flow of oil between the switch and expansion tank is ensured.
  • the cross-section of the pressure wave channel formed by the pipe section (R1) to the pressure relief valve (D1) is so large that pressure waves are passed unhindered to the pressure relief valve.
  • the oil channel in the expansion vessel is formed in the embodiment by the gap between the two pipe or guide pieces (R1) is designed so that it allows for the slowly running thermally induced volume fluctuations sufficient oil flow, for the explosive volume increases in case of damage but one such damping has that the pressure wave is not transmitted to the bellows but within the pipe socket (R1) to the pressure relief valve (D1) is performed.
  • FIG. 2 shows a tap-changer (S) with expansion vessel, a usual for tap changer protective relay (D2) via the pipe (R2) with the interior of the switch (S) is connected.
  • FIG. 3 shows an inventive embodiment of the switch expansion vessel in which a bellows (K) is installed as a negative compensator in the cylindrical expansion vessel.
  • the axial movement of the bellows leads to the adaptation of the volume.
  • the movable inner cover plate of the expansion vessel and the bellows (K) form a cavity which is used to accommodate the monitoring devices of the switch.
  • the movement of the cover plate (P2) is used on a display device (AV) for indicating the oil volume or the corresponding temperature of the insulating liquid of the tap changer.
  • FIG. 4 shows an inventive embodiment of the switch expansion vessel in which a bellows (K) as a positive compensator the volume fluctuations of the insulating liquid of the tap changer compensates.
  • a bellows (K) as a positive compensator the volume fluctuations of the insulating liquid of the tap changer compensates.
  • a fixed pot-shaped inner cylinder which encloses the monitoring devices of the tap changer.
  • This cup-shaped inner cylinder is advantageously largely adapted to the shape of the bellows (K) in the compressed state.
  • this inner cylinder serves at the same time as oil collection hood and splash guard for a pressure relief valve (D1) enclosed by this cylinder.
