Definitions

  • a surge arrester protected electrical surge arrester according to the preamble of claim 1.
  • This component has an insulator designed as a column, at the head of a first electrical potential, in particular high voltage potential, feasible first conductor system is attached.
  • a second electrical conductor system which can be guided to a second electrical potential, in particular ground potential, is fastened.
  • the first and the second current conductor system each have an arc electrode, which in turn each contain one of two spaced apart in the direction of the column axis and in the radial direction from the insulator annularly shaped electrode sections. An arc formed during an undesirable discharge between the two current conductor systems is commutated to the circular ring-shaped electrode sections. Under the action of the magnetic field of the current flowing in the annular electrode sections, the now predominantly axially aligned arc is set in rotation and then extinguished, for example, in the current zero crossing.
  • a surge arrester which contains two by a columnar outdoor insulator electrically insulated from each other and located at different electrical potentials conductor systems.
  • Each of these systems includes one each as an open, annular loop and in the region of the insulator head or the insulator foot at a distance from the Insulator led conductor section.
  • a surge arrester according to the preamble of claim 1 is in US 6,018,453 A specified. Also in this component unwanted arcs arc commutated on two spaced apart in the direction of an axis of the component arc electrodes, forced to rotate about the axis and so deleted, for example, in the current zero crossing.
  • the two arc electrodes are each formed as a plate in this component and are formed in the plates in each case a plurality of predominantly radially guided slots.
  • the invention solves the problem of providing an arc protected electrical component of the type mentioned, in which the eroding and corrosive effect of unwanted arcs is suppressed particularly effective.
  • At least one of the two arc electrodes is designed in the manner of a cup and has a cup wall attached to a power connection of the surge arrester and a cup wall which adjoins the cup bottom and extends predominantly in the direction of the axis of the insulator the at least two from the bottom of the cup to the Cup edge extended and mainly guided in the circumferential direction Materiataus strictly adopted are formed. Due to the cup-shaped design of the arc electrode, the emigration of an arc formed during operation of the inventive electrical surge arrester in a high voltage system arc favored from the point of origin on the surge arrester to the outside on the edge of the cup.
  • the design of the arc electrode as a cup is very essential for the stabilization of the arc fault, since the arc root is fixed to the cup rim in the axial and radial direction and can only move in the circumferential direction in the desired manner. In order to keep the material erosion of the arc electrode as low as possible, it is recommended to form the edge of the cup of erosion-resistant material.
  • a particularly effective design of the cup wall as a coil and thus a particularly rapid rotation of the arc fault is achieved if at least one of the two material recesses is designed as a slot and has two sections of different width.
  • a section of large slit width which adjoins the cup base is guided in the circumferential direction, whereas a second section of small slit width adjoining this section is guided predominantly in the circumferential direction and in the axial direction.
  • the height of the arc electrode extending in the direction of the column axis is at least 0.1 and at most 0.5 times its diameter.
  • Such a shaping can be achieved by casting or by deformation, for example crimping, of a preformed material recesses containing circular plate with a wall thickness between 2 and 25 mm.
  • the insulator is made hollow and an active part guided axially through the insulator is provided.
  • the surge arrester has an active part based on metal oxide.
  • the surge arrester shown has an open-air insulator 1 designed in the manner of a column and formed, for example, by a polymer, for example based on epoxy or silicone, or a ceramic, such as a porcelain.
  • the insulator is hollow and has an along an axis 2 (column axis) arranged, not apparent from the figure active part with at least one non-linear resistive element, preferably based on metal oxide, in particular zinc oxide.
  • a first electrical conductor system which can be guided to a first electrical potential, for example a high-voltage potential.
  • the first current conductor system is electrically conductively connected to the head end of the active part and has a connectable to a high voltage line power connector 3 and a designed like a cup Lichtelektode 4, which is open down towards the Isolatorfuss concentric with the axis 2 aligned.
  • the arc electrode 4 is surrounded concentrically by an upwardly closed cover 5.
  • the isolator foot is provided with a second electrical conductor system which can be guided to a second electrical potential, for example ground potential.
  • the second current conductor system is electrically conductively connected to the foot end of the active part and has a connectable to a ground conductor 6 and a power connector designed like a cup Lichtelektode 7, which is open towards the insulator head concentrically aligned with the axis 2.
  • the arc electrode 7 is concentrically surrounded by an upwardly closed cover 8.
  • the two arc electrodes 4 and 7 are made of electrically good conductive material, in particular copper or a copper alloy.
  • the downwardly facing edge 9 of the arc electrode 4 and the upward-facing edge 10 of the arc electrode 7 are each made of erosion-resistant material, such as a refractory copper-zinc, copper-tungsten or copper-chromium alloy.
  • the surge arrester is held by an insulator 11 fastened to the power connection 6.
  • the two arc electrodes 4 and 7 are arranged mirror-symmetrically with respect to one another.
  • FIGS. 2 and 3 The structure of the arc electrode 4 is made of FIGS. 2 and 3 seen. These figures can be seen that the arc electrode 7 has a cup bottom 12 and a subsequent to the cup bottom and extending mainly in the direction of the axis 2 of the column cup wall 13, in the five Arthurckecked from the cup bottom 12 on the cup rim 10 and guided mainly in the circumferential direction and formed as slots 14 material recesses are formed. Centrally to the axis 2, an opening 15 is provided in the cup base 12, through which a portion of the only in Fig.1 shown power connector 6 is guided.
  • Each of the five slots 14 has two sections 16, 17 of different width, of which one on the cup bottom 12 attaching portion 16 has a large slot width and is guided in the circumferential direction.
  • a section 17 adjoining the section 16 has a small slot width and is guided predominantly in the circumferential direction and in the axial direction on the cup rim 10.
  • Two adjacent slots 14 are separated from each other by a current conductor 18 formed by the material of the cup wall. This current conductor 18 is mainly axially guided between the slot portions 16 of the two adjacent slots 14 and then between the slot portion 17 of a slot 14 and the slot portion 16 of the other slot 14 to the cup rim 10 mainly in the circumferential direction.
  • an insulating material such as preferably a polymer based on silicone, epoxy, polycarbonate or polyamide
  • the arc electrode 4, 7 from contact, for example by animals or by falling good, protected.
  • the environment is protected from the action of heated material, which is possibly thrown away from the component under the effect of the arc fault and represents a not inconsiderable fire risk.
  • Such protected components can therefore be used without problems in arid areas with fire-threatening vegetation, such as dried grass or bushes.
  • the arc can be outwardly directed away from the insulator with a particularly high degree of certainty when the cup wall 13 is inclined at an angle of 30 ° to 60 °, preferably approximately 45 °, relative to the cup bottom and if the height of the arc electrode 4 or 7 extending in the direction of the column axis 2 is at least 0.1 and at most 0.5 times its diameter.
  • the material recesses provided in the arc electrodes 4 and 7 do not necessarily have to be designed as slots 14, but may also be designed as grooves. In certain components, it may also be sufficient if only one of the two arc electrode has 4 or 7 cup shape.
