Definitions

  • the invention relates to a method of assembling an electric transformer. More particularly, the invention relates to a method where coils of the transformer are compressed during the assembly.
  • Electric transformers usually comprise at least two coils, namely at least one primary coil for inputting electrical energy and at least one secondary coil for outputting electrical energy.
  • the relation between the number of windings of the primary coil and the number of windings of the secondary coil determines the electric characteristics of the transformer.
  • transformers may be immersed in transformer oil that both cools and insulates the windings of the coils.
  • transformer oil that both cools and insulates the windings of the coils.
  • such oil-filled transformers undergo prolonged drying processes to ensure that the transformer is completely free of water vapor before the cooling oil is introduced.
  • a method for drying the active part of a transformer is described in German Patent Application DE 195 01 323 A1 .
  • the transformer is coupled to a vacuum pump, and the windings are supplied with a low frequency heating current that causes the solid insulation within the transformer to have gas or water content removed.
  • Document KR100699542B discloses a method of forming a transformer wherein coils and core are assembled together and then put in a drying oven.
  • the coils are usually compressed in order to avoid that the coils might change their size and position under the exposure of high electrical currents.
  • An embodiment of the invention relates to a method of assembling an electric transformer, comprising the steps of:
  • An advantage of this embodiment is that both drying and compressing may be carried out simultaneously. Therefore the assembling may be carried out very time efficient and cost-saving.
  • the exposure of the dried and compressed coil to the ambient atmosphere may be substantially shortened compared to prior art assembly.
  • the electromagnetic component may immediately be inserted into a transformer vessel which may be filled with oil or evacuated after the insertion of the electromagnetic component. There is no need to compress the coils outside the oven under ambient atmosphere because the coils have already been compressed during the drying and are ready for final assembly in the transformer vessel.
  • the step of combining the electric coil and the transformer core to form the electromagnetic component may comprise the step of mounting the coil on the transformer core or the step of mounting the transformer core on the coil.
  • the coil may slightly change its size. This effect may be addressed by using a tunable press.
  • the tunable press allows generating a defined mechanical pressure over time even if the coil changes its size over time during the drying process.
  • a hydraulic press is used to apply the mechanical pressure.
  • the hydraulic press may comprise a pressure cylinder and a control unit that controls the pressure applied to the coil whilst the coil is dried.
  • the press is controlled to apply a constant mechanical pressure over time during the step of drying the coil.
  • the press is controlled to modify the mechanical pressure over time during the step of drying the coil.
  • a predefined pressure profile may be applied during the drying step.
  • the predefined pressure profile may address an anticipated change of size of the coil during the drying step.
  • the pressure that is applied by the press is preferably monitored. This allows controlling the press to maintain the pressure on a predefined level or to provide a given pressure profile over time.
  • the size of the coil may be measured whilst the mechanical pressure is applied by the press and the coil is dried. This allows adapting the pressure on the coil to achieve a predefined coil size after completing the drying step.
  • the step of drying the electromagnetic component may be - at least temporarily - carried out in a kerosene containing gas or in vacuum.
  • at least those parts of the press, which are in contact with the coil, are preferably kerosene-resistant and/or vacuum-resistant.
  • the mechanical elements for ensuring that the mechanical pressure previously provided by the press is steadily maintained may comprise pull rods and/or wedges.
  • the step of forming the electromagnetic component preferably includes providing a closed magnetic circuit in the electromagnetic component before the drying in the drying oven is started.
  • Figure 1 shows in an exemplary fashion an E-shaped transformer core 10.
  • the shape of the transformer core may vary in a wide range .
  • the shape shown in Figure 1 has been chosen for illustrating purposes, only, and may be replaced by any other core shape.
  • the core shape might be chosen differently to accommodate the required number of coils.
  • a coil 20 is mounted such that the middle section 11 of the transformer core penetrates the coil 20 (see Figure 2 ).
  • the coil 20 may comprise primary and secondary windings which are not shown in further detail.
  • the E-shaped transformer core 10 is provided with an I-shaped core element 30 which is placed on top of the E-shaped transformer core 10 (see Figure 3 ) . If electric current flows through the windings of coil 20, a magnetic flux will be generated as schematically indicated by reference sign 40.
  • the original size of the coil 20 before the compressing is indicated by reference sign H.
  • the resulting electromagnetic component 50 which comprises the E-shaped transformer core 10, the I-shaped transformer element 30, and the coil 20, is then subjected to a drying step.
  • the drying step is preferably combined with a step of compressing the coil 20 such that both steps are carried out simultaneously.
  • a tunable press 60 is attached to the coil 20.
  • the press 60 is preferably a hydraulic press which comprises a pressure cylinder 61 and a control unit 62.
  • the control unit 62 controls the pressure applied by the pressure cylinder 61 and therefore regulates the extent to which the coil 20 is compressed.
  • the size of the compressed coil 20 is designated by reference sign h (h ⁇ H) in Figure 4 .
  • the electromagnetic component 50 is moved into a drying oven 70 as shown in Figure 5 .
  • the entire press 60 may be moved into the drying oven 70 as shown in Figure 5 .
  • the sequence of the above discussed steps of attaching the hydraulic press 60 and moving the electromagnetic component 50 into the drying oven 70 may be opposite.
  • the electromagnetic component 50 may be moved into the drying oven 70 before the hydraulic press 60 in its entirety or parts thereof (for instance the pressure rods 63 and/or the pressure cylinder 61), are mounted on the coil 20.
  • mechanical elements 80 are attached to the coil 20. These mechanical elements 80 prevent the coil 20 from increasing its size if and when the hydraulic press 20 is detached from the coil 20. In other words, the mechanical elements 80 ensure that the mechanical pressure previously provided by the hydraulic press 60 is maintained without interruption.
  • the mechanical elements 80 is attached in the drying oven 70.
  • Figures6 and 7 illustrate the removal of the 60 or its parts outside the drying oven 70.
  • the assembled transformer is designated by reference numeral 100.
  • FIGS 10 and 11 illustrate the removal of the press 60 or its parts inside the drying oven 70.
  • the mechanical elements 80 are attached to the electromagnetic component 50 before the press is detached.
