Definitions

  • the invention is based on an arc protected electrical component according to the common preamble of claims 1 and 4.
  • the invention also relates to a specific for this component arc electrode.
  • the component has an insulator designed as a pillar, to the head of which a first current conductor system, which can be guided to high-voltage potential, is fastened.
  • a second current conductor system which can be routed to ground potential, is fastened.
  • the first and the second conductor system each have an arc electrode for receiving an arc occurring during a discharge between the first and second conductor system.
  • At least one of both arc electrodes is designed in the manner of a cup. In the cup wall at least two arc edge forming the cup edge are formed. An arc formed during an unwanted discharge between the two conductor systems is commutated to the edge of the cup. Under the action of the magnetic field of the electric arc feeding the arc and guided in the cup rim to the arc of the predominantly axially aligned arc arc is set in rotation and deleted in the current zero crossing.
  • the invention relates to a prior art of arc protected electrical components, as in EP 1 283 575 A1 is described.
  • a disclosed in this prior art and designed as a surge arrester component contains two electrically isolated by a columnar outdoor insulator from each other and located at different electrical potentials conductor systems.
  • each This conductor system has an arc electrode for receiving an arc occurring during a discharge between the two conductor systems.
  • the two arc electrodes are cup-shaped.
  • a plurality of arc fingers are formed, which form portions of the cup rim.
  • the supply current of the arc flowing in these sections to the foot of the arc provides for a radially directed magnetic field at the base of the arc.
  • the arc is therefore subjected to a tangentially directed electrodynamic force and rotated along the edge of the cup around the insulator until the arc extinguishes.
  • the arc is now predominantly aligned axially and is based on the two circumferentially guided, annular arc electrodes. Due to electromagnetic forces of the arc flashes on the arc electrodes fussend as long as the insulator of the component until it is extinguished in the zero crossing of the arc fault current. The component is thus protected against the eroding and corrosive effect of the arc fault.
  • the invention as defined in the claims solves the problem of providing an arc protected electrical component of the type mentioned, in which the effect of arcing arcs is particularly effectively suppressed by suitable design of an arc electrode.
  • the arc fingers each have two successively in the circumferential direction of the cup wall finger portions, of which a cup edge distant portion of a first of the fingers and the axis are skewed and a cup edge forming portion of a second of the fingers at a distance in Axially to the cup edge remote portion is held in the cup wall. Because of this arrangement and design of the arc fingers, a strong, predominantly radially directed magnetic field builds up over the entire cup rim at the base of the arc fault. It acts on the cup edge held at the base of the arc always a large, tangentially directed, electrodynamic force, which causes a rotation of the arc root until the extinction of the arc in the current zero crossing.
  • the continuity of the force is given by the fact that regardless of its current position on the edge of the cup, a radially directed strong magnetic field is constantly maintained in the arc root. Even with the transition from a finger to the following finger in the circumferential direction of this magnetic field is maintained, since at least one of the two superimposed finger portions predominantly in the tangential direction flowing current receives with the same sense of direction, which continues at the arc root as a predominantly axially guided arc current.
  • a comparatively small number of arc fingers is required if the cup rim-forming section of the arc fingers is guided predominantly tangentially is.
  • the predominantly tangential guide also includes curvatures of the cup edge forming portions in the axial direction.
  • the arc fingers are arranged skewed to each other over their entire length and the axis.
  • the arc fingers each have two predominantly tangentially guided portions, one of which is attached to the cup bottom and the other forms the cup rim, each arc finger has an at least in the axial direction guided middle portion of the bottom of the cup Section with the cup edge forming portion connects, and the cup edge forming portion of a first of the fingers is held at a distance in the axial direction to the bottom side portion of a second of the fingers in the cup wall.
  • the central portion is guided not only in the axial direction, but at the same time in the tangential direction.
  • the central portion and the axis are then skewed to each other.
  • the bottom portion and the misaligned midsection then provide the transition from the central portion of the cup rim for a good current loop and thus for the desired strong radial magnetic field at the arc root.
  • a sufficiently strong magnetic field at the transition point from one finger to the other can also be achieved if the middle section is guided predominantly axially and optionally radially.
  • the cupola side portion should only be formed by a relative to the diameter of the section relatively narrow air gap from the cup edge forming Separate section, otherwise the radial component of the magnetic field at the location of the arc root may be too low.
  • the arc electrode provided on the insulator head is formed by a current connection supplying the first electrical potential.
  • This embodiment also has the advantage that an emigration of the arc arc is avoided by the otherwise provided on the insulator head and having direction of rotation electrode on the power connector due to the thermal effect of the arc fault.
  • Opposing rotations of the arc root points are achieved if the arc electrode arranged on the insulator head has a different direction of rotation than the arc electrode arranged on the insulator base. These opposing movements lead to a particularly effective magnetic blowing of the arc fault.
  • the insulator is made hollow and an active part guided axially through the insulator is provided. Therefore, particularly preferred components are outdoor bushings, surge arresters, in particular with an active part based on metal oxide, current transformers, voltage transformers or switches. If, on the other hand, the component has only supporting function, then the insulator can also be solid.
  • the surge arrester illustrated in FIG. 1 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 conductor system is electrically connected to the head end of the active part and has a connectable to a high voltage line Power connection 3 and formed in the manner of a cup arc electrode 4, which is open towards the bottom Isolatorfuss concentric with the axis 2 aligned.
  • This electrode can be made, for example, by casting or material-lifting, such as by turning and milling.
  • 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 a downwardly closed cover 8.
  • the two arc electrodes 4 and 7 are made of good electrically conductive material, in particular copper or a copper alloy, such as brass. In a particularly advantageous manner, this material may comprise graphite or another material particularly resistant to erosion.
  • At least the downwardly facing edge 9 of the arc electrode 4 and the upward-facing edge 10 of the arc electrode 7 are made of erosion-resistant material, such as a refractory brass, a copper-tungsten or copper-chromium alloy.
  • the two arc electrodes 4 and 7 are arranged mirror-symmetrically to each other.
  • FIGS. 2 and 3 The construction of the arc electrode 4 can be seen in FIGS. 2 and 3. These figures can be seen that the arc electrode 7 has a cup bottom 11 and a subsequent to the cup bottom and extending in the direction of the axis 2 of the column cup wall 12, formed in the six the cup rim 9 forming identically formed and spaced by air gaps 13 arc fingers are. From Fig.2 only the four fingers 21, 22, 23 and 24 are visible. These fingers are each extending predominantly in the circumferential direction and each have three axially spaced-apart and circumferentially successive sections. The three sections can only be seen for the two fingers 22 and 23 from FIG. 2 and are designated in sequence with the reference signs a, b, c and a ', b', c 'respectively.
  • a labeled with the reference a or a 'portion of the finger 22, 23 sets at the bottom 11 and is also tangentially guided as a cup edge forming section c or c '.
  • the two sections a and c or a 'and c' are connected by a predominantly tangential, but obliquely to the axis 2, guided, cup side remote section b and b 'with each other.
  • Section b or b 'and axis 2 are skewed to each other.
  • cup-distal portion b 'of the finger 23 and cup-forming portion c of the finger 22 are the cup-distal portion b of the finger 22 and cup-forming portion c "of the finger 21 and cup-distal portion b" of the finger 24 and cup-forming portion, respectively c 'of the finger 23 are held one above the other at an axial distance in the cup wall 12.
  • an opening 14 is provided in the cup base 11, through which a portion of the power connector 6 shown only in Fig.1 is guided.
  • a tangentially directed, large electrodynamic force always acts on the base 15 of the arc (FIG. 2) held on the cup rim 9, which causes a rotation of the arc until its extinction in the current zero crossing.
  • the continuity of the force is given by the fact that in the arc root 15 regardless of its positioning on the cup rim 9 consistently a radially inwardly directed strong magnetic field is maintained. This continuity results from the previously described design and arrangement of the arc fingers. If the arc is located on section c of finger 22, section c in FIG. 2 is indicated by an arrow Current I, which continues in the axially directed arc (shown as a jagged arrow in Fig. 2).
  • the current therefore forms a well-formed current loop at the arc root point 15 and generates at the location of the base point 15 away from the observer, ie radially inwardly, directed strong magnetic field.
  • a tangentially directed force acting counterclockwise on the arc which leads the base point 15 to the air gap 13 separating the two fingers 22 and 23. Regardless of whether the base point 15 has not yet partially or completely overcome the air gap, the radially inwardly directed magnetic field is maintained since at least one of the two sections b 'and c receives the current I.
  • the arc electrode 4 embodied according to FIG. 4 has only two arc fingers 22 and 23.
  • the cup edge and cup edge forming portions b, c 'and b', c of both fingers 22 and 23 are axially spaced apart from each other as in the above-described embodiment, so that this embodiment has the same advantageous effects.
  • this electrode can be realized particularly easily, but at the expense of the mechanical stability of the arc fingers.
  • the current loop caused by the transition from the section a 'to the section b' applied perpendicular thereto generates a magnetic field whose component in the radial direction is sufficient to continue the arc root point on the cup rim 9 at the transition from one arc finger 23 to the adjacent 22.
  • the arc fingers, z. B. 22 to 23, need not necessarily have an exclusively tangentially guided cup edge forming finger portion c or c '. Loop formation and a sufficiently high radial field are still achieved even when the arc fingers and the axis 2 are skewed to each other (embodiment of the electrode 4 according to Figure 6) or if only the cup edge remote section b, b 'and the axis 2 skew each other are, however, the cup edge forming portion c, c 'tangentially (embodiment of the electrode 4 according to Figure 7) or curved out (embodiment of the electrode 4 according to Figure 7 with dashed trays edge forming portion c' of the arc finger 23 ').
  • the arc fingers engage the cup base 11 with the section b, b 'guided obliquely to the axis 2.
  • the tangentially guided section a, a 'present in the embodiments according to FIGS. 2 to 5 can therefore be dispensed with in principle, since sections b, c and b', c 'of successive arc fingers 22, 23 provide a sufficiently high radial magnetic field during current flow can.
  • 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 area is also in front of the Protected by 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.
  • These embodiments of the electrode can be formed in a simple manner by stamping and cold forming a sheet, for example by punching a flat, the material recesses containing precursor body 25 of the electrode from the sheet and then bending a sheet metal flap located between each two material recesses 16 to form six contact fingers and the air gaps 13 arranged therebetween (for reasons of clarity, only four fingers 21 to 24 are designated in FIGS. 8 and 9).
  • This can be achieved in manufacturing technology particularly simple manner executed in the manner of a polygon cup base 11, at the corners of each of the material recesses 16 is arranged (embodiment of FIG. 8 with a formed like a polygon cup rim).
  • the cup wall 12 is inclined in all the illustrated embodiments predominantly at an angle of 90 ° relative to the cup base 11, but may also, without losing the advantageous effects described above, include a deviating angle of at most 150 ° and at least 30 °.
