Definitions

  • the invention relates to a surge arrester according to the preamble of patent claim 1.
  • Surge arresters are protective systems, for example, for switchgear, which in the event of overvoltages caused by lightning strikes or malfunctions of other subsystems dissipate these overvoltages to ground and thus protect other components of the switchgear.
  • Such a surge arrester comprises one or more cylindrical diverting elements, which have a varistor column made up of individual, likewise cylindrical varistor elements.
  • Varistor elements are characterized by a voltage-dependent resistance. At low voltages these act as insulators. From a certain threshold voltage, which is material-dependent, they show a good conductivity.
  • varistor elements are made of metal oxides such as zinc oxide.
  • the diverter is limited at both ends by end fittings that make electrical contact with the switchgear and ground. To ensure a good electrical contact even under mechanical stress, the varistor column must be held together under pressure. This can be done by tension members, for example, ropes or rods are preferably clamped in glass fiber reinforced plastic in the end fittings under train. The tension elements surround the varistor column and thus form a cage around them.
  • a fluid-tight housing which surrounds the discharge element.
  • the housing is to increase the dielectric strength with a fluid, usually sulfur hexafluoride, filled.
  • the housing is usually made of metal and is electrically grounded.
  • An end fitting of the Ableit yarn is Grounded via a guided through the housing contact.
  • the other end fitting is electrically connected via a passage with a contact located on the outside of the housing, which serves to connect to the switchgear.
  • surge arrester must be disconnected from the switchgear because of the high voltages which then occur. Otherwise, the surge arrester would divert the voltage to ground and the measurement result would be corrupted. Because of this, surge arresters sometimes have a disconnecting device, with which the surge arrester can be disconnected from the switchgear.
  • the bushing has a high-voltage contact for each diverting element, which establishes a gas-tight electrical connection from the interior of the housing to the exterior of the housing.
  • the implementation is often made of cast resin, in which the high-voltage contacts are cast. The position of the contacts is often specified by the operator or manufacturer of the switchgear. So far, the housing with the arrangement of the diverters and possibly the separator had to be constructed thereon.
  • a surge arrester is known whose Ableitelement is arranged concentrically to the high voltage contact.
  • a movable control hood serves as a separator.
  • a surge arrester with three Ableit yarn is known.
  • the Ableit yarnlen are arranged radially outwardly offset from the high voltage contacts.
  • a guided through the end fitting of the Ableitiata contact element is displaceable by means of a push rod in the axial direction and makes the connection to the high voltage contact or separates them.
  • overvoltage arresters have in common that the location and arrangement of the Ableit yarnlen is determined by the geometry of the high voltage contacts.
  • the object of the present invention is to provide a surge arrester with more flexible design options.
  • a surge arrester has a fluid-tight housing and a discharge element arranged in the fluid-tight housing.
  • the diverter element comprises a diverter column made of varistor elements, an end fitting at each of the ends and tension elements clamped in the end fittings and arranged around the diverter column and aligned with its longitudinal axis parallel to the housing axis.
  • the surge arrester comprises a bushing with a high voltage contact, which electrically connects the interior with the exterior of the housing (2), and a contact element, which is electrically connected to the discharge element, and via which an electrical connection from the discharge element to the high voltage contact can be produced.
  • the contact element is arranged eccentrically to the longitudinal axis and the position of the contact element is adjustable in a plane perpendicular to the longitudinal axis.
  • the contact element can be set to different positions of the high voltage contact and / or the diverter can be positioned differently within the setting limits of the contact element with the same position of the Ableitides.
  • the surge arrester can be adapted to feedthroughs with different arrangements of high voltage contacts, without this resulting in structural changes to other components.
  • the diverting element can be arranged independently of the arrangement of the high-voltage contact, whereby a more flexible construction is made possible.
  • the contact element is connected by an eccentric disc with the discharge element.
  • the eccentric disk is rotatable about the longitudinal axis.
  • the contact element is eccentric on the eccentric, so spaced from the longitudinal axis and mechanically and electrically connected thereto.
  • the eccentric disk is made of an electrically conductive material.
  • a rotation of the eccentric disc about the longitudinal axis causes a rotation of the contact element about this on a circular path.
  • the high voltage contact can now be positioned anywhere on this circular path. If the position of the high-voltage contact and thus of the contact element is fixed, the diverting element can be arranged arbitrarily on the circular path around the contact element.
  • the contact element is designed like a pin and inserted in an eccentrically arranged to the longitudinal axis guide bore of the eccentric disc. This opens up constructive degrees of freedom in a particularly simple manner.
  • the eccentric disc has a cylindrical recess which is concentric with the longitudinal axis. In this recess an end fitting of the discharge element can be inserted. If end fitting and recess are round, then the eccentric disc can rotate freely around the end fitting. Also possible is a polygonal design of end fitting and recess. Then the eccentric disc can be rotated in steps corresponding to the number of corners around the longitudinal axis of the end fitting.
  • the contact element is arranged in both variants on the recess of the opposite side of the eccentric disc. In this way, a rotatable electrical and mechanical connection between the discharge element and the eccentric disc can be produced particularly simply by plugging together.
  • the contact element is displaceable parallel to the longitudinal axis by means of a displacement device.
  • This is an electrical Connection between diverting element and high-voltage contact can be produced or separated.
  • the displacement device is preferably adjustable to different positions of the contact element.
  • the contact element in the guide bore of the eccentric disc in the longitudinal direction that is guided parallel to the longitudinal axis, slidably guided.
  • a surge arrester with a separator can be constructed much easier, since a changed arrangement of the high voltage contact has no constructive effect on the separator. The adjustment of the separator to the position of the contact element can be easily done during assembly.
  • the displacement device has a connecting rod connected to the contact element and a gas-tight from the inside of the housing outwardly and outside the housing by an actuator movable central rod.
  • a coupling element with the central rod and the push rod is connected, wherein the coupling element is connected by means of a connecting element with the push rod.
  • the connecting element is guided by a guide rod connected to the housing in a direction parallel to the longitudinal axis. This ensures an independent of the discharge element leadership of the connecting element and thus the push rod.
  • the guide rod is fixedly connected to a first end of the housing cover. This allows a particularly simple installation.
  • a second end of the guide rod inserted through a hole in the connecting element and the connecting element along the guide rod is displaceable. This also serves for easier installation.
  • the coupling element has an arm which is connected to the coupling block and inserted into a bore of the connecting element. It attacks the guide rod in a groove of the arm so that the connecting element is fixed in a direction perpendicular to the longitudinal axis direction. This allows a simple mating of the displacement device without gluing, screws or other fixing means.
  • an intermediate piece is arranged in the housing, which has a first end fitting which is connected concentrically to the longitudinal axis with the high-voltage contact and a second end fitting which is inserted into a second eccentric disk.
  • the contact element is inserted into a second guide bore of the second eccentric disc.
  • Means of the intermediate piece can be a housing with a certain length equipped with different lengths of discharge elements. The length compensation takes place by the opposite to the diverting considerably simpler spacers.
  • the two eccentric discs are rotatably arranged around the respective end fitting, the contact element connects both. As a result, the diverting element and intermediate piece can be positioned freely relative to one another in a wide range.
  • the intermediate piece has a second discharge element.
  • the number of varistor elements required for a particular switchgear is thus divided between two diverting elements. The smaller part is arranged in the second discharge element. This simplifies warehousing, since only the smaller intermediate piece in different lengths must be kept in stock.
  • the surge arrester has a plurality of diverting elements and a plurality of high-voltage contacts, wherein the number of diverting elements is equal to that of the high-voltage contacts.
  • the diverting elements are preferably arranged rotationally symmetrically on a first pitch circle about the housing axis.
  • the high-voltage contacts are also preferably rotationally symmetrical arranged on a second pitch circle around the housing axis.
  • Each of the diverting elements has an adjustable contact element.
  • the contact elements are set so that their position lies on the second pitch circle. Discharge elements and high voltage contacts can thus lie on different pitch circles. With a constant diameter of the first pitch circle, the contact elements are adjustable to different diameters of the second pitch circle.
  • the surge arrester with constant arrangement of Ableitiata on bushings with different arrangement of the high voltage contacts is adjustable.
  • a fuselage surge arrester so a surge arrester without implementation, prefabricate and assemble with different feedthroughs to a surge arrester by the contact elements are set to the respective arrangement of the high voltage contacts in the implementation during assembly.

  • the contact element 9 is arranged on the outside of the eccentric disc 60 spaced from the axis of rotation.
  • the contact element 9 is moved on a circular path about the longitudinal axis 40 and can thereby be adjusted radially to the housing axis 50.
