Definitions

  • the invention relates to a Studentsnapssableitvortechnisch having a Ableitstrombahn which has a voltage-side terminal and a ground-side terminal, wherein in the Ableitstrombahn a switchable separation path of a disconnecting switching device is arranged.
  • Such Matternapssableitvoriques is for example from the published patent application DE 10 2012 217 310 A1 known.
  • the local overvoltage discharge device is equipped with a discharge flow path, which extends from a voltage-side connection to a ground-side connection.
  • a switchable separation path of a separation switching device is arranged in the Ableitstrombahn. It is provided in the known Kochnapssableitvortechnik to arrange a plurality of Ableitstrombahnen parallel within a housing. The multiple leakage current paths can be separated via a respective separation path. It is provided that switching contact pieces of the separation sections in valve bodies of Ableitstrombahnen are movably guided via a centrally arranged between the individual Ableitstrombahnen mechanism.
  • an object of the invention to provide an overvoltage diverting device, which allows a simplified operation of a switchable separation path of a disconnecting switching device in a Ableitstrombahn.
  • the object is achieved in an overvoltage diverting device of the type mentioned above in that the isolating distance is arranged on the ground-side terminal.
  • Surge arresters are used to reduce overvoltages in electrical systems.
  • overvoltages may occur which in some cases significantly exceed the rated voltages. For example, this can occur by switching action within electric power transmission networks.
  • overvoltage can also occur due to external influences. For example, it may happen that lightning strikes lead to voltage increases in electrical power transmission lines of electric power transmission networks.
  • Overvoltage diverters are devices for protecting electrical power transmission equipment from overvoltages. Upon occurrence of voltages exceeding a threshold, a leakage current path is formed to dissipate the overvoltages by flowing a ground fault current through a temporarily formed ground fault path.
  • the overvoltage discharge devices preferably operate in an automated manner, so that when an overvoltage limit is reached, an earth fault path controlled by the discharge current path is switched through. After a reduction of the overvoltage, e.g. Upon reaching a rated voltage or a limit, the Ableitstrombahn is automatically interrupted to resume normal operation of the electric power transmission network can. Accordingly, the Ableitstrombahn a surge arrester is preferably switched on or off voltage-dependent.
  • a separation path of a disconnecting switch By means of a separation path of a disconnecting switch is given the opportunity to take the surge arrester temporarily out of service, so that, for example, at Tests an undesirable response of the surge arrester counteracted.
  • the operating state of the surge arrester device can be restored by means of the disconnecting switching device.
  • the separation distance of the disconnecting device is closed.
  • a current limiting impedance element may be located, which limits an undesirable increase in a leakage current or in particular voltage-dependent switching the Ableitstrombahn makes (voltage-dependent impedance element).
  • such an impedance element may be a level spark gap or else a varistor, in particular a metal oxide varistor.
  • the separation distance By arranging the separation distance at the ground-side connection of the Ableitstrombahn, ie in particular between a ground-side terminal and an existing possibly in the Ableitstrombahn current limiting impedance element, the possibility exists in the immediate vicinity of the ground potential (earth connection point) pressing the separation distance and an arrangement of Disconnecting device to make.
  • This can also be a provision of extensive actuation means which have to bridge electrical differences isolated electrically, are dispensed with.
  • the high and high voltage range in which correspondingly large impact widths would have to be bridged by means of the actuating means, can be dispensed with costly actuating means.
  • Due to the earth-side arrangement of the separation section controls or control means can be moved near the earth.
  • the disconnecting switching device is arranged away from live parts in the operating state (eg voltage-side connection of the leakage current path) of the surge arrester device. Simplified accordingly the design of the separation switching device can be made.
  • the earth-side connection is the connection to a discharge flow path, which leads to ground potential and allows a leakage current to be conducted into a ground potential
  • the voltage-side connection of the discharge flow path is that connection which, in the operating state, carries an electrical potential.
  • a voltage drop Between the voltage-side terminal and the ground-side terminal is thus a voltage drop, which drops, for example, a current limiting, in particular voltage-dependent impedance element.
  • this potential separation can be resolved, for example, by changing the electrical behavior of a particular voltage-dependent impedance element in the Ableitstrombahn, so that, driven by the potential difference, via the Ableitstrombahn by the impedance element and the closed separation line a leakage current flows against ground potential ,
  • a further advantageous embodiment can provide that the leakage current path has a current limiting, in particular voltage-dependent impedance element, which is arranged with the separation distance within a housing.
  • a housing makes it possible to arrange a current-limiting, in particular voltage-dependent impedance element within a protected space.

  • the dielectric configuration thereof can be carried out in a simplified manner.
  • the housing may be designed as a fluid-tight housing, so that penetration or escape of fluids into or out of the housing is prevented.
  • This makes it possible to fill the housing with an electrically insulating fluid, which is different from a fluid which can surround the housing.
  • the housing may be configured as a pressure vessel, so that in the interior of the housing can also prevail deviating from the environment pressure.
  • the housing can act as a pressure-resistant barrier, which withstands a differential pressure between the inside and outside of the housing.

Due to the electrically insulating properties of the support means, a separation of the impedance element from deviating electrical potentials can be ensured. If the separation section is now spanned by means of the electrically insulating support device, the separation section itself can be mechanically stabilized by the support device. Furthermore, the electrically insulating support device can cause electrical isolation of the separation path.
