Definitions

  • the invention relates to an electrical connector comprising a tulip-type electrical contact.
  • Such electrical connectors are typically used in medium or high voltage electrical equipment, for example equipment configured to operate with voltages higher than 72.5 kV or even above 550 kV.
  • Such equipment may comprise circuit breakers, disconnectors or grounding devices.
  • Fig. 1 represents a tulip-type female electrical contact 10 having a known structure.
  • This electrical contact 10 includes a ring 11 of conducting fingers 13, as well as a base 12 carrying the fingers 13.
  • the conducting fingers 13 comprise a plurality of adjacent metal blades 15 with slots 19 therebetween substantially in the form of a cylinder with a central longitudinal axis 14.
  • the distal ends 16 of the fingers 16 form contact pads designed to engage a male electrical contact 20.
  • the male mechanical contact 20 is provided to make electrical contact with the conducting fingers 13.
  • a plurality of holes 17 are provided at the bottom of the slots 19 separating the fingers 13, in order to decrease the intensity of the mechanical and electrodynamic stresses exerted at the junctions between the base 12 and the fingers 13.
  • these holes 17 must be small to limit dielectric gas leaks and to ensure a satisfactory mechanical strength of the tulip 10.
  • DE 27 39 032 A1 discloses a gas blast circuit breaker whose switching system has one contact which consists of spring loaded segments surrounding the other contact. There is further a sliding contact ring. This ring is designed as the arcing electrode and is provided before the contact segments of the second contact assembly. It initiates the separation of contacts and arc pulling during the contact opening process. The sliding contact ring rests with a radial clearance on the second contact, and is pressed by a spring to an eccentric position.
  • DE 3 624 636 A1 discloses a contact system for an electrical gas-blast circuit breaker.
  • DE 198 16 508 A1 discloses a burn-off contact arrangement in which contact fingers are connected to a first electric terminal by flexible ribbons consisting of superposed strips of e.g., copper in order to create a large burn-off reserve.
  • the invention seeks to provide a solution to problems described.
  • the object of the invention is to provide a female electrical connector for a medium or high voltage electric line.
  • a female electrical connector according to the invention is disclosed in claim 1. It comprises a tulip-type female electrical contact for electrically contacting a male electrical contact, by surrounding the male electrical 10 contact.
  • the female electrical contact comprises a ring of conducting fingers and a base portion carrying the fingers.
  • the female electrical contact comprises a pressing element configured to exert a force on the fingers when the female electrical contact is in a rest position wherein the female electrical contact is free of electrical contact with the male electrical contact.
  • the female electrical connector also includes a support for the pressing element, arranged around the ring, the pressing element projecting from within the support. The pressing element reduces the intensity of the mechanical stresses exerted at the junction region of the fingers.
  • the pressing force of the fingers about the male contact tends to increase, with an identical maximal deflection of the fingers.
  • the mechanical stresses exerted on the fingers are higher at the point of contact of the pressing element on the fingers than at the junction region between the fingers and the base.
  • the electrical connector is relatively cheap to manufacture and compact.
  • the invention can optionally include one or more of the following characteristics.
  • the pressing element is configured to exert a radial pre-stress on the fingers, when the female electrical contact is in the rest position.
  • the pressing element ensures that the diameter of the tulip remains substantially constant : diameter over time, despite wear of the tulip.
  • the pressing element promotes better electrical connection between the male contact and the female contact for the lifetime of the female electrical contact.
  • the position of the pressing element along a length of the conducting fingers is adjustable.
  • the pressing element has the shape of an annulus centred on a centre axis of the ring, the annulus having a constant width.
  • the annulus is preferably a circlip, having a substantially constant width.
  • the pressing element and the support are fabricated as an integral component.
  • Each of the conducting fingers extend from the base to a distal end opposite to the base and according to the invention, the pressing element is positioned closer to the base than the distal end of the conducting fingers so as to exert a force on the fingers away from the base.
  • the location of the pressing element thereby allows a sufficient gap of the fingers upon inserting the male electrical contact between the fingers, while decreasing the mechanical strains exerted on the fingers.
  • a distance between the position of the pressing element and the base is between 0 % and 30 % of the total length L 1 of the fingers.
  • the female electrical contact is configured to slide inside the support.
  • the female electrical contact is fixed with respect to the support and, in this case, the male electrical contact is configured to slide inside the support to electrically engage the female contact.
  • the invention also relates to an electrical apparatus comprising a female electrical connector as defined above and a male electrical connector to engage the female electrical contact.
  • the male electrical contact is configured to be inserted into the ring of fingers of the female electrical contact, so as to be in electrical contact with the female electrical contact.
  • the electrical apparatus is preferably a circuit breaker, a disconnector or a grounding device.
  • the invention also relates to a method for assembling a female electrical connector or an electrical apparatus as defined above.
  • the method comprises a step of introducing the female electrical contact inside the support so that the pressing element exerts a force on the fingers.
  • the introduction of the female electrical contact inside the support is facilitated by the pressing element.
  • the method offers the possibility to modify an existing female electrical connector to insert a pressing element about the fingers.
  • the pressing element presses on the fingers so as to exert a radial pre-stress on the fingers during the step of introducing the female electrical contact into the support.
  • a radial pre-stress on the fingers during the step of introducing the female electrical contact into the support.
  • the method comprises a step of inserting the pressing element around the fingers, before introducing the female electrical contact into the support.
  • the modification of existing female electrical connectors is significantly easier in that the pressing element is independent of the support.
  • Fig. 3 represents a circuit breaker 1 for a medium or high voltage electric line.
  • the circuit breaker 1 includes a female electrical connector 3 and a male electrical connector 2.
  • the female electrical connector 3 comprises a female electrical contact 10.
  • the female electrical contact 10 is located within an interrupter tube of the circuit breaker 1.
  • the circuit breaker 1 also comprises a support 30 arranged to at least partially surround the female electrical contact 10.
  • the male electrical connector 2 is of a known structure and will not be described in detail herein.
  • the male electrical connector 2 comprises a male electrical contact 20 configured for insertion in the female electrical contact 10, thereby electrically contacting the female electrical contact 10.
  • the female electrical contact is a tulip-type female electrical contact 10.
  • the circuit breaker 1 is represented in an open position, in which the female electrical contact 10 is positioned away from the male electrical contact 20 and is free of electrical and mechanical contact with the male electrical contact 20.
  • the female electrical connector 3 In this open position of the circuit breaker 1, the female electrical connector 3 is in a mechanical and electrodynamic rest position.
  • the female electrical contact 10 surrounds the male electrical contact 20 and is in electrical contact with the male electrical contact 20.
  • the female electrical contact 10 is substantially annular about a central axis 14.
  • the female electrical contact 10 comprises a ring 11 of conducting fingers 13 supported by a base 12 on which the fingers 13 are mounted.
  • the fingers 13 project outwardly from the base 12 toward a distal end 16.
  • the fingers 13 comprise metal blades 15, preferably of copper or an alloy thereof which are favoured for their high electrical conductivity.
  • the metal blades 15 are configured to be mechanically deformable so as to move away from each other when a male electrical contact 20 is engaged between the fingers 13.
  • the fingers 13 take the form of electrical contact pads.
  • the contact pads curve inwardly so that the distance between the contact pads and the central axis 14 is less than the distance between the blades 15 and the central axis 14 closer to the base 12.
  • the conducting fingers 13 are arranged side by side and are separated by cylindrical slots 19 extending along the central axis 14 of the female electrical contact 14. The width of the slots 19 varies along the length thereof and are widest close to the base 12, gradually tapering to zero or nearly zero width at the distal ends 16 of the fingers 13.
  • the female electrical connector 3 also comprises a pressing element 4 configured to exert a force on the fingers 13 including when the female electrical contact 10 is in its rest position as defined above.
  • the pressing element 4 presses against an outer surface of the fingers 13. More precisely, the pressing element 4 exerts a radial pre-stress on the fingers 13, both when the female electrical contact 10 is in the rest position and in a closed position of the circuit breaker. This radial pre-stress decreases the diameter of the ring 11 in the open position of the circuit breaker 1.
  • the pressing element 4 thereby promotes maintaining a diameter of the fingers 13 substantially constant during the lifetime of the female electrical contact 10, despite deformation and wear of the female electrical contact 10. In this manner, the pressing element 4 : ensures better electrical contact between the male element 20 and the female electrical contact 10 even after the tulip-type electrical contact 10 is worn.
  • the pressing element 4 is in direct mechanical contact with the fingers 13 away from the base 12, by being closer to the base 12 than the distal ends 16.
  • the position of the pressing element4 relative to the ring 11 is determined so as to limit the mechanical stresses exerted at the junction of the base 12 and fingers 13 as far as possible. More precisely, the distance l 1 between the pressing element 4 and the base 12 is between 0 % and 30 % of the total length L 1 of the fingers 13.
  • the maximum stress y 2 generated by inserting the male electrical contact 20 is located at the point of contact of the pressing element 4 on the fingers 13.
  • the fingers 13 can be regarded as beams embedded at the base 12 in a simple flexion.
  • the fingers 13 due to the radial pre-stress exerted thereon by the pressing element 4, the fingers 13 may be regarded as having a flexion characteristic of beams embedded at the base 12 in a substantially punctiform manner.
  • the pressing element 4 is fabricated as an integral component with the support 30 and has the shape of an annular boss projecting from within the support 30 to the ring of fingers 11.
  • the : embodiment represented in Fig. 4 differs from that of Fig. 3 in that the pressing element 4 has the shape of an annulus centred on a centre axis 14 of the ring 11.
  • the annulus is a circlip, that is, it has a substantially constant width l 2 .
  • the annulus-shaped pressing element 4 is attached to the support 30, so as to project from within the support 30.
  • the pressing element 4 is also in direct mechanical contact with the support 30.
  • the position 34 of the pressing element 4 along the length of the fingers 13 from the base 12 is adjustable.
  • the pressing element 4 is located at a distance from the base 12 corresponding to between 0 % and 30 % of the total length L1 of the fingers 13. The adjustment of the position 34 of the pressing element 4 enables the distribution in the stresses exerted onto the fingers of the female electrical contact 10 to be more readily controlled.
  • the radial pre-stressexerted by the pressing ring 4 causes a change in the radial orientation of the fingers 13 with respect to the base 12 on either side of the pressing element 4 when the male electrical contact 20 electrically engages the female electrical contact 10. More specifically, in the rest position of the female electrical contact 10, an angle ⁇ between the base 12 and each finger 13 is less at a position above the pressing ring (i.e., between the pressing ring and the distal end 16 of the finger 13) than below the pressing ring (i.e., between the base 12 and the pressing ring 4). This discontinuity of the slope 131, 132 of the fingers generated by the pressing element 4 limits the clearance of the fingers in the proximity of their distal end 16.
  • a method for assembling the female electrical connector 3 represented in Fig. 3 and 4 comprises a step of introducing the female electrical contact 10 within the support 30, so that the pressing element 4 exerts a force on the fingers 13.In particular, the pressing element 4 exerts a radial pre-stress on the fingers 13 on introducing the female electrical contact into the support 30.
  • the method for assembling the female electrical connector of Fig. 4 further comprises a step of inserting the pressing element 4 around the fingers 13, before introducing the female electrical contact into the support 30.
  • the fingers 13 are made of a material that has a good electrical conductivity and a low mechanical strength.
  • the pressing element 4 facilitates restriction of mechanical stresses in the region of the base 12 which is strongly biased.
  • the pressing element 4 also contributes to improve the resistance of the female electrical contact to electrodynamic strains related to the short-circuit current in the circuit breaker. These electrodynamic stresses result in particular from the fingers heating upon closing the apparatus.
  • the pressing element 4 exerts a radial pre-stress, so as to decrease the diameter of the female electrical contact 10 at rest.
  • the positioning of the pressing element 4 around the fingers 13 results in a difference in the angular orientation (i.e., the slope) of the fingers on either side of the pressing element.
  • the pressing element 4 is in mechanical contact only with the fingers 13, when the female electrical contact 10 is at rest.
  • the electrical apparatus described above and represented in Fig. 3 and 4 is a circuit breaker 1 for a medium or high voltage electric line.
  • the apparatus may also be a disconnector or a grounding device, with the female electrical contact designed to be located in an active part thereof.
