Definitions

  • the invention relates to a medium- or high voltage pole part with at least one heat sink element, according to the preamble of claim 1.
  • the temperature rise especially in the region of the contact terminal has to be limited.
  • a pole part of a circuit breaker arrangement with a heat sink element arranged near the upper electrical contact terminals is disclosed in EP 2 720 244 A1 .
  • This heat sink element is additionally heavy and compact with a relatively high mass, in order to fulfill a double function, as a heat sink, and as a bouncing absorber for absorbing shock energy from the movement of the moving contact in the end position.
  • the function as heat sink near the upper contact terminal is advantageous, in order to dissipate away the heat, which occurs there by the effect of electrical power loss of electrical conducting part and transition resistance between electrical contacting parts.
  • the known heat sink element which is very solid and heavy has its main function, in compensation of bouncing energy. Therefore, the installion is much more complex than necessary.
  • the invention is, that the heat sink element is U-shaped in such, that it is mountable by shifting and clamping it on the pole part body, from the contact face side of the pole part.
  • heat sink is used on top of the pole part, as shown in the aforesaid EP 2 720 244 A1 .
  • heat will be dissipated in a much more effective way, by the contour structures, which are positioned closely at that point of the vacuum interrupter pole part, where heat occurs, for example by electrical transition resistance.
  • the assembly of the heat sink elements on the pole part is much easier.
  • the heat sink element can be retrofitted much easier.
  • a preferably thin U shaped heat sink is fixed to the contact arms of the terminals of the vacuum circuit breaker pole part. This heat sink will get the local power loss dissipated to the surrounding of the pole part of the vacuum circuit breaker.
  • multiple plate that means multiple layered structure can be used in order to increase the heat dissipation, like decribed in the following text.
  • U-shaped heat pipe can also be used.
  • slots, holes, ribs, cubic, cylinder, radius ribs features could be added into this U shaped part in order to enforce the heat dissipation of this part.
  • U-shaped heat sink element consist of two opposing flanks which are both fixed at a bottom element, so that the so structured heat sink element is a one piece element. So it surrounds the pole part closely for good heat transition.
  • each of the opposing flanks of the U-shaped heat sink element consist of at least two layers arranged spaced apart, and that the at least two layers per flank are fixed at the common bottom element.
  • a final advantageous embodiment is, that the bottom element is provided with a c-formed recess in such, that the c-conture of this recess is arrangend partly around the external wall of the electrical contact terminal.
  • the Invention is used in vacuum interrupter arrangements in such, that the vacuum interrupter is mounted on a frame, with medium- or high voltage pole parts according to one of the aforesaid claims, wherein the heat sink elements are U-shaped.
  • the heat sink elements are provided furthermore with a bridge element at the open side of the U-shape contour, in order to form the heat sink element finally into a O-shaped contour, surrounding the pole part around the main axis.
  • a bridge element at the open side of the U-shape contour, in order to form the heat sink element finally into a O-shaped contour, surrounding the pole part around the main axis.
  • two U- or L-shaped contour could be fixed together around the contact arm, to form this O-shaped contour.
  • the pole part is provided with such heat sink element at both contact terminals, the upper contact terminal and the lower contact terminal.
  • a three phase arrangement 1 of three pole parts on a circuit breaker are provided with an U-shaped heat sink element 2 at each electrical contact or terminal arm 3.
  • the U-shape is created as such, that the heat sink element can be inserted from the front side, that means from the contact face side of the pole parts of the circuit breaker.
  • the U-shaped heat sink element can be fixed to the contact arm of a vacuum circuit breaker pole part. This heat sink will get the local power loss dissipated to the surrounding of the pole part of the vacuum circuit breaker.
  • FIG. 2 shows a further detailed heat sink element 2, like defined by the further depending claims in a special advantageous embodiment. So the heat sink element 2 will be inserted on the terminals of the pole part in the same way, like mentioned above. Here is shown, that the flanks of the heat sink element are splitted into two layers 2' and 2" each. This multiplies the active heat emitting or dissipating surface. The fact that the layers are arranged as such, that in the mounted position, a vertically oriented slot will be between the layers, this will support cooling convection between them by normally vertically upstreaming convention of the air.
  • FIG 3 An alternative, or a combinable further embodiment of the heat sink is shown in figure 3 .
  • the flanks are provided with a number of parallel cooling slots 4, which are arrangend here in a L-shape. This also supports cooling by convenction. This slot arrangement can also be combined with the double or multilayered flanks of the heat sink element, as shown in figure 2 .
  • U-shaped heat pipe can also be used.
  • the contact surface between them should be machined properly with good mechanical fit to each other, which results in low transit thermal resistance.
  • Possible heat conductive paste could be also used to have a low thermal restistance in between.
  • the surface area should be also dimensioned so, that the heat could be transferred properly.
  • Last but not least, painting or coating with an insulating material on the surface of the heat sink elements can be also used for increase the thermal radiation and improve the dielectric performance.
  • Figure 4 shows once more in detail an embodiment of the heat sink element 2.
  • a half round or better a C-formed recess 5, which is placed over the contact arms 3, like shown in figure 1 .
