Definitions

  • the invention relates to a spark gap arrangement with at least three electrodes and with at least two holding frames which are arranged flat one above the other, the holding frames each having an edge which surrounds a recess for receiving at least one electrode.
  • the invention also relates to a holding frame for such a spark gap arrangement.
  • a variety of surge protection devices are known from the prior art and are used to protect electrical devices or lines from surges that can be caused, for example, by lightning strikes or defects in technical systems. Spark gap arrangements with multiple electrodes have been used for decades in the area of overvoltage protection in electrical devices and systems. In order to dissipate high overvoltages while at the same time ensuring a high mains follow current extinguishing capacity, multiple spark gaps are often used, which are often referred to as stacked spark gaps due to their structure. Such stacked spark gaps consist of several electrodes and several insulations, which are arranged between the individual electrodes, so that there is insulation between two electrodes, which has an opening in the middle, so that two electrodes form a spark gap.
  • the electrodes are generally designed as circular or rectangular graphite disks, between which corresponding ring-shaped or frame-like insulation is then arranged.
  • the insulations are often designed as thin insulation films made of plastic, for example PTFE, and are generally less than 1 mm thick.
  • a stacking spark gap is known in which the installation space or space requirement is reduced by the fact that the individual electrodes are perforated in the middle and the contact plates arranged on the end faces of the stacked electrodes are connected to one another by a guide rod, which perforates the individual electrodes and the perforations of the ring-shaped insulation passes through.
  • the DE 10 2016 114 787 A1 discloses a carrier unit for spark gaps that can be connected and stacked in series, which consists of an insulating body that has a recess for the electrode.
  • the insulating body is designed such that it accommodates a single electrode, with several insulating bodies then being stacked one on top of the other.
  • a radial opening is additionally formed in the insulating body, which is connected to the receptacle for the electrode, so that the electrode can be contacted through the opening on its radial outer surface.
  • the DE 10 2011 102 864 A1 discloses a stacked spark gap with several individual spark gaps connected in series, with the individual electrodes each being arranged in an insulating body.
  • the insulating bodies each have a recess for receiving a disk-shaped electrode and a receptacle for a control element, the receptacle for the control element being connected to the recess for the electrode.
  • a control element is connected to the edge of the electrode via a contact spring, so that triggering of the individual electrodes of the stack spark gap can be achieved via the control elements.
  • the DE 10 2018 118 898 B3 discloses a holding arrangement for several electrodes, which consists of at least two holding frames that can be stacked flat on top of each other.
  • the individual holding frames In the individual holding frames, three recesses are formed next to each other to accommodate one electrode per recess, so that three stacking spark gaps arranged next to one another can be realized by stacking several such holding frames on top of one another.
  • a corresponding number of openings connected to the recesses are formed in the individual holding frames, through which the outer surfaces of the individual electrodes can be contacted. The openings are formed on one long side of the holding frame, so that the individual electrodes can be contacted from this side.
  • stacked spark gaps are known from the prior art, in which the individual electrodes are each arranged in a frame-shaped insulating body.
  • the individual disc-shaped electrodes are contacted on their narrow side, i.e. on their outer surface arranged in the longitudinal extent of the stacked spark gap.
  • the present invention is therefore based on the object of providing a spark gap arrangement which enables contacting of the individual electrodes even when using particularly narrow electrodes.
  • a holding frame should be provided that can be used in such a spark gap arrangement.
  • At least one receiving opening is formed in the edge of at least one holding frame, in which a control element is arranged.
  • the individual holding frames are arranged twisted relative to one another about their central axis M, which is arranged perpendicular to the plane of the holding frame, in such a way that the receiving opening of a first holding frame is located above an electrode which is accommodated in a second holding frame arranged underneath is.
  • the spark gap arrangement preferably consists of several electrodes and accordingly also of several holding frames, so that the spark gap arrangement is a multiple spark gap or stacked spark gap.
  • the individual holding frames - and with them the electrodes accommodated in them - are then arranged as a stack mounted twisted around the center.
  • the at least one receiving opening in the holding frame is arranged near a corner of the holding frame.
  • the arrangement of the receiving opening near a corner of the holding frame makes it possible for the angle by which the individual holding frames arranged one above the other must be arranged twisted relative to one another to be relatively small.
  • the individual holding frames are each arranged twisted relative to one another to such an extent that the electrode arranged underneath can be contacted in the area of a corner by a control element arranged in a receiving opening.
  • angles of rotation of less than 15°, in particular less than 10°, for example 7.5°, may be sufficient.
  • the individual holding frames each have a collar-shaped support section directed inwards towards the central axis M, against which at least one electrode comes into contact.
  • the electrodes are therefore not held in their position, at least not only by the edge of the holding frame surrounding the recess, even if the recesses are adapted to the outer dimensions of the electrodes, but also by the fact that the edge of the electrodes rests on the collar-shaped support section of the on the holding frame.
  • the support section is opposite the edge of the Holding frame is set back in the direction of the central axis M. An electrode can come into contact on both sides of the collar-shaped support section.
  • the collar-shaped support section also takes on the function of the insulation foils between the individual electrodes, which are otherwise often used in stacking spark gaps.
  • the individual electrodes By placing the individual electrodes on the support section of the respective holding frame, two electrodes that are at least partially accommodated by a holding frame thus have a defined distance from one another, which is predetermined by the thickness of the support section.
  • a spark gap arrangement can be realized which has very small dimensions, in particular in the longitudinal extent of the spark gap arrangement or the stacked spark gap.
  • a spark gap arrangement has two holding frames, a total of three electrodes can be accommodated by the two holding frames, with the middle electrode being arranged between the two holding frames and thus being held together by both holding frames.
  • the two outer electrodes on the other hand, only have one end face, the front or the back, resting on a support section of a holding frame, while the other end face is electrically contacted by a contact plate and held in the holding frame.
  • a spark gap arrangement with n holding frames can therefore accommodate n + 1 electrodes. Since the two outer electrodes can each be contacted via a contact plate, n - 1 control elements can be provided in such a spark gap arrangement, which correspondingly contact n - 1 electrodes.
  • the holding frames can have an approximately rectangular shape. However, this does not exclude the possibility that the holding frames have an outer contour and an inner contour, each of which deviates from that of a rectangle.
  • the outer contour of the holding frame, which deviates from a rectangle, can be used in particular to provide space for the arrangement of the receiving opening for the control element in the edge of the holding frame.
  • the edge of the holding frame can have a section that projects outwards, in which case the receiving opening for the control element is formed in the area of the section.
  • the inner contour of the holding frame is determined by the inner edge of the support section.
  • the collar-shaped support section can have an octagonal inner edge, with individual inner angles being able to have different values. If, in the spark gap arrangement according to the invention, two holding frames are arranged rotated relative to one another by an angle ⁇ , it is preferably provided that four internal angles ⁇ 1 have a value of 90° + ⁇ and four internal angles ⁇ 2 have a value of 180° - ⁇ . The different interior angles ⁇ 1 and ⁇ 2 are arranged or formed alternately relative to one another in the circumferential direction.
  • the specific shape of the holding frame in particular its inner contour, is therefore designed depending on the angle at which individual holding frames are arranged twisted relative to one another or the angle of rotation between the individual holding frames depends on the specific shape of the holding frame .
  • the individual holding frames are designed such that they are locked in their mutually twisted arrangement. This also simplifies the positioning of the individual holding frames relative to one another and ensures that the position of the individual holding frames relative to one another, in particular the angle by which adjacent holding frames are rotated relative to one another, does not unintentionally change again during assembly of the spark gap arrangement.
  • the holding frames can each have at least one locking element on at least one side, with two locking elements of two holding frames interacting when the two holding frames are stacked one above the other in the intended, mutually twisted arrangement.
  • the holding frames can each have at least one latching element on the front and a counter-latching element on the back, the latching element of a holding frame engaging in a counter-latching element of a second holding frame when the two holding frames are stacked one above the other, twisted relative to one another by the intended angle ⁇ are.
  • pin-shaped pins and corresponding pin holes as counter-locking elements can be provided as locking elements.
  • the individual electrodes of the spark gap arrangement are preferably designed as rectangular, in particular square, thin disks made of graphite or a tungsten-copper composite material.
  • the thickness of the electrode disks can be less than 5 mm, in particular less than 3 mm.
  • the task mentioned at the beginning is achieved in a holding frame for a corresponding spark gap arrangement with the features of patent claim 9.
  • the holding frame has an edge which surrounds a recess for receiving an electrode, the recess being adapted to the external dimensions of the electrode. According to the invention it is provided that at least one receiving opening is formed in the edge of the holding frame for receiving a control element.
  • the holding frame preferably has a collar-shaped support section for at least one electrode directed inwards towards the central axis M of the holding frame, the support section preferably being set back relative to the edge of the holding frame in the direction of the central axis M.
  • the outer contour and the inner contour of the holding frame are preferably designed in such a way that they deviate from that of a rectangle, with the collar-shaped support section in particular having an octagonal inner edge.
  • the inner edge preferably does not correspond to a regular octagon, with eight interior angles ⁇ of equal size. Rather, the inner edge preferably has four internal angles ⁇ 1 and four internal angles ⁇ 2 , which are arranged alternately with one another.
  • the interior angle ⁇ 1 is 90° + ⁇ and the interior angle ⁇ 2 is 180° - ⁇ .
  • the holding frame can consist of a plastic or a ceramic material and have a relatively small thickness of preferably less than 10 mm, in particular less than 5 mm. In principle, however, other insulating materials for the holding frame and other dimensions, in particular other thicknesses, are also possible.

  • a spark gap arrangement 1 consists of at least three electrodes 2 and at least two holding frames 3 that accommodate the electrodes 2, the holding frames 3 being arranged flat one above the other.
