Definitions

  • the present invention concerns a protection device for discharge current with a transverse exhaust direction.
  • Such a spark gap comprises two connection assemblies.
  • Each connection assembly comprises an electrode and a conductive terminal cooperating with the corresponding electrode.
  • the two electrodes are arranged in proximity so that an overvoltage beyond a certain threshold applied to the conductive terminals generates an electric spark.
  • the ignition of the spark gap engenders very fast exhausting gas, which should be taken into account.
  • Document US5754385 discloses a device according to the preamble of claim 1.
  • the present invention relates to a protection device according to claim 1.
  • oriented toward an exhaust direction opposed to the housing means that an airflow passing through the exit section is moving away from the housing.
  • the direction defined according to the alignment of the rear area and the front area and called height direction is not to be understood as limitative with reference to the geometry of the protection device. It simply defines a geometric direction that is equivalent to an extension direction defined according to the rear area and front area alignment.
  • the exit section is opening outside the insulating casing, which means that there is no wall of the insulating casing in front of the exit section in the exhaust direction. An airflow is then able to exit the exhaust channel directly outside the insulating casing.
  • the exhaust channel is configured to exhaust air from the housing in case of an overpressure in the housing.
  • the protection device is configured to cooperate with a receiving station and/or a receiving bracket of a base facilitates the insulation measurements on an installation and the replacement of the protection device at the end of its life. Indeed, no cable needs to be disconnected.
  • the protection device can comprise a two of spark gaps mounted in series. This enables to protect several phases of an installation with a single protection device.
  • the exhaust direction is transverse to the height direction allows exhausting air in a direction that does not disturb a user that is located in front of the front area.
  • the cooperation between the protection device and the receiving station is maintained, as there are no constraints according to the height direction on these parts.
  • the front area includes a grip portion. This allows an easy handling of the protection device.
  • the two spark gap are aligned according to a direction transverse to the height direction and to the exhaust direction.
  • each spark gap corresponds an insulating casing as described in this text.
  • the spark gap is a gas-filled spark gap.
  • the plurality of walls are forming two exhaust channels.
  • the two exhaust directions of the two exhaust channels are opposed so as to define two exhaust airflows flowing in an opposed way.
  • the two exhaust directions are aligned or parallel or inclined with an angle of less than 5 degrees.
  • This arrangement enables to stabilize the protection device as the constraints engendered by the two airflows are canceling each other.
  • the exhaust channel presents an entrance elbow starting from the opening, a straight portion connected to the entrance elbow and extending along the housing, and, an exit elbow including the exit section.
  • the exhaust channel that is provided with an entrance elbow and an exit elbow enables to orient the airflow in a direction that will not disturb the cooperation between the protection device and the receiving station and/or the receiving bracket of a base.
  • the particular arrangement of the exhaust channel makes it possible to prevent the overpressure from causing the ejection of the protective device of the reception station. Indeed, the orientation in the exhaust direction suppresses the strength that might remove the protection device from the base and/or receiving station.
  • the entrance elbow and the exit elbow are portions of the exhaust channel wherein an airflow passing through is diverted from an initial airflow direction to a final airflow direction that is transverse to the initial airflow direction.
  • the straight portion is extending according to a direction parallel to or inclined at an angle of less than 5 degrees to the height direction and/or the opening formed in the housing is oriented in a direction transverse to the height direction.
  • oriented in a direction means that an airflow passing through the opening is mainly oriented according to said direction.
  • This arrangement allows reducing the constraints on the protection device and/or the receiving station when an overpressure appears in the housing. Indeed, the generated airflow is diverted and is not directly aimed at the receiving station.
  • the straight portion and the housing are delimited by a separating wall of the plurality of walls, the separating wall being contiguous to the opening.
  • the separating wall has a dual purpose of defining the limit of the housing and a side of the straight portion.
  • the exit elbow comprises an exit wall contiguous to the exit section and linked to the separating wall.
  • This construction is a simple way of creating the exhaust channel and in particular the exit elbow with an easy and efficient design.
  • the entrance elbow and the straight portion comprise a diverting wall of the plurality of walls located at least in part in front of the opening in a parallel way to the exhaust direction.
  • the diverting wall constitutes a turning wall that realizes the rotation of the airflow in the entrance elbow.
  • the diverting wall is partly facing the separating wall. This allows defining the straight portion of the exhaust channel with a simple construction.
  • the protection device comprises a recess configured to cooperate with a receiving bracket of a base, the recess being formed in the rear area.
  • the recess is configured to cooperate with a rail.
  • the protection device comprises an interlock mechanism configured to releasably secure the protection device on a receiving station in a mounted position, the first conductive terminal and the second conductive terminal being configured to respectively cooperate with a first complementary terminal and a second complementary terminal of the receiving station in the mounted position.
  • the presence of the interlock mechanism facilitates the insulation measurements on an installation and the replacement of the protection device at the end of its life. Indeed, no cable needs to be disconnected.
  • the interlock mechanism is configured to cooperate with the receiving station according to an insertion direction until the mounted position is reached, the straight portion extending parallel to or at an angle of less than 5 degrees to the insertion direction in the mounted position.
  • the exhaust direction is transverse to the insertion direction.
  • the opening and/or the exit section are oriented transverse to the insertion direction.
  • oriented in a direction means that an airflow passing through the opening and/or the exit section is mainly oriented according to said direction.
  • This arrangement allows maintaining the protection device in the mounted position, as in case of an overpressure in the housing there are not constraints on the protection device according to the insertion direction unmounting the protection device.
  • the interlock mechanism comprises two latch elements, each latch element being arranged to cooperate with a corresponding complementary latch element of the receiving station in the mounted position, the two latch elements being symmetric according to a central plane of the protection device.
  • This arrangement enables an easy insertion in the mounted position and a good position keeping as two symmetrical latch elements are used.
  • the two latch elements are formed on two extremities of the insulating casing, the extremities being aligned in a direction transverse to the height direction. This arrangement participates to the good position keeping.
  • the two latch elements comprise each a captive screw, a quarter-turn system screw or snap-in system part.
  • the complementary latch elements are screw thread or complementary snap-in system parts.
  • the spark gap is provided with a deionization chamber
  • the first connection assembly comprises a first guiding member
  • the second connection assembly comprises a second guiding member
  • the first guiding member and the second guiding member being configured so as to allow the formed electric spark to be guided toward the deionization chamber
  • the first guiding member, the second guiding member and the deionization chamber are located in the housing.
  • the deionization chamber is at least partially aligned with the opening in a parallel way to the exhaust direction.
  • This arrangement allows the airflow generated by an electrical spark to leave the housing rapidly as the exhaust channel is near. The duration of the overpressure in the housing is then reduced.
  • the deionization chamber includes a plurality of aligned plates configured to form small electric sparks between adjacent plates.
  • the plates of the plurality of plates extend parallel to or at an angle of less than 5° to the height direction.
  • the plates of the plurality of plates are aligned according to a direction transverse to the height direction.
  • This arrangement enables a compact construction of the housing as the opening is near the deionization chamber.
  • the plurality of walls are forming two exhaust channels configured in a symmetric way compared to a central symmetry plane of the deionization chamber.
  • This arrangement allows a better evacuation of the airflow generated by an electric spark as a higher flow rate is enabled.
  • the symmetry between the two exhaust channels enables the creation of two identical flow outing the two exit sections, which cancels the constraints on the protection device transversally to the height direction.
  • the present invention also concerns an electrical system comprising a protection device as described above and a receiving station configured to cooperate with the protection device in mounted position, the electrical system also presenting an extension channel or two extension channels when applicable, the or each extension channel realizing, in mounted position, a fluidic connection between the corresponding exhaust channel and an exterior area, the exterior area being contiguous to the electric system when the protection device and the receiving station are in mounted position.

  • the or each extension channel comprises a final portion extending in parallel way to or at an angle of less than 5° to the corresponding exhaust direction.
  • extending means that an airflow passing through the final portion is moving in a parallel way or inclined at an angle of less than 5° to an airflow passing through the exit section.
  • the or each extension channel is formed in the protection device and/or in the receiving station.
  • This arrangement allows having a compact electrical system wherein the extension channel is easily integrated without necessitating additional space. This arrangement also enables to adapt to different protection device and receiving station designs.
