Definitions

  • the invention relates to a Studentsnapssabieiter with thermal overload protection and its use and a method for protecting a surge arrester before thermal overload.
  • An object to be solved is to provide a thermal overload protection for a surge arrester and a method that safely and easily protect the surge arrester from thermal overload. Furthermore, a use must be specified.
  • the surge arrester has at least two electrodes; it can be a two-electrode as well as a three-electrode surge arrester.
  • the surge arrester forms an interior space by means of a tubular insulator, preferably a ceramic cylinder, and external electrodes or external connections arranged at its front ends.
  • the at least two electrodes are soldered or welded to the external terminals and are typically opposite to each other as pin electrodes or as a tube electrode and Pen electrode, which projects into the tube electrode is formed.
  • the interior of the surge arrester is gas-tight against the environment and contains a gas.
  • Surge arresters serve in particular to short-circuit high pulse-shaped voltages of a few kV and currents of a few kA in a very short time or to discharge them to ground.
  • a load that lasts longer in the event of a fault for example if a mains current is short-circuited via a power supply network or via a telecommunication network or a voltage distributor (power cross), may result in an excessively high heating of the surge arrester, which possibly leads to a fire.
  • a surge arrester is thermally stressed under a load with DC or AC voltages or with DC or AC currents. This case can sometimes also occur in lightning protection applications.
  • Surge arresters in the field of network protection serve to protect the network against lightning impulse currents and against overvoltages.
  • arcing occurs when a certain threshold voltage is exceeded.
  • the arc is maintained by the feeding current as long as the electrical conditions for the arc are met.
  • the arc creates a thermal load on the surge arrester that must not exceed specified values for the surge arrester and for its installation environment. Unacceptably high temperatures may cause the surge arrester to catch fire.
  • Surge arrester is normally connected to the associated external terminal of the surge arrester with the aid of a fusible element under normal operating conditions.
  • the fusible element establishes an electrical contact and mechanically connects the electrode to the external connection.
  • the surge arrester further includes an extinguishing device configured to extinguish an arc.
  • the arc either burns when the surge arrester responds between the two electrodes, or develops between the one electrode and the outer terminal when the fuse contacts and melts.
  • the extinguishing device is triggered by the melting of the fusible element at too high a thermal load.
  • the extinction of the arc is accomplished by extending the distance that the arc can travel or travel from one electrode to the other electrode or to the outer electrode of the surge arrester.
  • the electrical circuit that is closed during the arcing between the electrodes of the surge arrester and the voltage or current source connected to the external electrodes is disconnected. As a result, a circuit is interrupted, so that no further thermal load occurs.
  • the surge arrester with extinguishing device is set up so that the external integrity of the surge arrester is maintained even when the extinguishing device is triggered.
  • External integrity means that the housing assembly of the surge arrester remains intact and no Parts that could cause damage outside the surge arrester may be detached or blown off.
  • the extinguishing device is preferably arranged completely in the interior of the housing of the surge arrester.
  • the extinguishing of the arc prevents thermal overloading from causing excessive overheating of the surge arrester and ignites the surge arrester. At the same time, it is possible that an arc-extinguishing gas or medium from the outside of the surge absorber flows into the interior of the surge absorber or into the vicinity of the extinguishing device and an arc generated by the separation process is extinguished.
  • the melting element has the properties of a low-melting solder.
  • a soft solder or a braze can be used. This ensures that, in the event of thermal stress on the surge arrester, first the solder of the melting element is melted before the remaining elements of the surge arrester can be damaged. The melting solder triggers the extinguishing device and an existing or resulting from the melting arc is deleted.
  • the fusible element is configured to melt upon inadmissible heating and to cause the erasing device to move the one electrode to a position farther from the other electrode of the surge absorber, or to increase the distance formed therebetween.
  • This embodiment makes it possible, by the movement of the one electrode not only to provide an extension of the distance between these two elements with respect to the other electrode, but also to move the one electrode out of the interior of the surge arrester so that it becomes safely inoperative. This achieves a particularly efficient protection against thermal overloading of the surge arrester and the device protected by it.
  • the one electrode is formed in several parts and contains, in addition to the main electrode of the actual surge arrester, an auxiliary electrode with which the electrode is fixed in the surge arrester. Furthermore, the electrode has a pin pointing away from the interior of the surge arrester, which pin is electrically connected to the outer electrode by means of the fuse element.
  • the fusible element is formed so that a gap is formed between the outer electrode and the one electrode connected thereto. In this gap is inadmissible heating of the surge arrester and a melting of the
  • Melting element moves an insulating element, so that the connection between the outer terminal and the one electrode is separated and interrupted.
  • the extinguishing device has a spring with which the movements required for the insulation are implemented.
  • the spring has the advantage that on the one hand the melting element mechanically biased and upon release of the fusible element by a relaxation of the spring an efficient movement of the leading electrode or the insulating element is performed to perform the insulation.
  • the spring is provided as a compression spring or as a tension spring.
  • a compression spring has the particular advantage that the spring support can be easily performed.
  • the extinguishing device is in one of the not connected to the melting electrode of the
  • the separated space accommodating the extinguishing device can be optimally designed for the function to be performed by the extinguishing device.
  • the separated space may contain a gas or a medium, which helps in triggering the melting element or the use of the extinguishing device to extinguish the resulting arc as efficiently as possible.
  • the spring is particularly preferably designed as a compression spring, which is biased in the normal state, ie without response of the fusible element between the outer terminal and the one electrode. This makes it possible that when melting the
  • Melting element relaxes the spring and this movement pulls the electrode from the interior of the surge arrester and separates from the outer terminal.
  • the shape of the insulating element is adapted to the shape of the electrode.
  • the insulating member preferably has the shape of a pot whose walls are between the
  • an embodiment of the spring is provided as a tension spring.
  • molten melting element With molten melting element, it is possible to actuate a contact element upon reaching the end position after the movement of the one electrode. By the spring and the contact element, an electrical contact is closed and generates an electrical signal. This electrical signal can be used for further processing, be used for example to display the functional state of the surge arrester.
  • the surge arrester can be used in a device which places high demands both on faultless operation and on thermal and other loads.
  • These include, for example, a power supply network, e.g. in a building, or a telecommunication facility or a telecommunications network, which can be efficiently protected against lightning and other surges with the surge arrester.
  • the surge arrester is not limited in its use and can also be used in any other electrical circuit in which high voltages must be dissipated by means of a surge arrester.
  • Overvoltage arrester on the fusible element designed to melt in the event of excessive thermal stress before other parts of the surge arrester can catch fire.
  • an extinguishing device is triggered which extends a path extending from one electrode of the surge arrester to the other electrode of the surge arrester or to the outer electrode.
  • the extension of the route is effected in that in a preferred method step, the electrode is moved away from the other electrode and is further away in its end position. there the external integrity of the surge arrester is maintained.
  • an insulating element is moved into a space between the one electrode and the outer electrode with the aid of the extinguishing device.
  • the one space is formed by melting of the fusible element and released for the movement of the insulating element.
  • a contact element upon melting of the fusible element with the aid of the extinguishing device, a contact element is activated which generates an electrical signal and forwards it to a display or control device.
