Definitions

  • the invention relates to a surge arrester with cage design, as for example from the JP 63-312602 is known.
  • Surge arresters are connected in power supply systems between live lines and ground to derive in the event of an overvoltage in the line this to ground and to protect other components of the power grid.
  • Such a surge arrester contains a stack of varistor blocks, which is held between two connection elements. This arrangement is accommodated in an outer housing.
  • Surge arresters are capable of safely dissipating overvoltages occurring within their design range as often as possible to ground.
  • the varistor blocks usually zinc oxide ceramic elements, have the property that their electrical resistance is voltage-dependent. That is, below a threshold voltage, the varistor blocks are good insulators. Above this voltage, however, they are well electrically conductive.
  • surge arresters with "tube design", in which the active components are housed in a tube, for example made of ceramic or a dimensionally stable plastic.
  • a gas volume remains in the interior of the outer housing.
  • the outer casing of this surge arrester is further provided with a gas outlet opening, through which the hot plasma can escape in the event of an overload, whereby an increase in pressure inside the outer casing is prevented.
  • the outer housing itself usually remains undamaged even when overloaded.
  • surge arresters in which the outer casing is poured or sprayed directly around the active components.
  • a high quality plastic usually silicone is used, as for example in the EP-0 963 590 B1 is described.
  • a disadvantage of tube-type surge arresters is that partial discharges may occur via the volume of gas between the core and the outer housing. To avoid this, the entry of moisture into the gas volume should be prevented. Often a gas with better insulator properties than air is used. It must also be avoided that an exchange of the gas with the ambient air or the ingress of moisture occurs. Surge arresters with tube design are therefore relatively expensive to manufacture. Despite these disadvantages, surge arresters with tubular design are particularly widespread at extremely high voltages of several hundred thousand volts, as with surge arresters with a height of several meters are possible.
  • surge arresters with direct-encapsulated outer housings have no enclosed gas volume, which simplifies the construction.
  • the hot plasma will destroy the outer casing locally in the event of an overload and thus escape to the outside.
  • the outer casing should be as thin-walled as possible.
  • a substantial portion of the cost of producing the surge arrester of this type is due to the outer casing material, which is relatively expensive. Therefore, the person skilled in the art endeavors to form the outer housing with as little material as possible.
  • Surge arresters of this type have heretofore been at relatively low voltages, i. limited to tens of thousands of volts. For higher voltages, several surge arresters were connected in series.
  • the object of the invention is therefore to provide a surge arrester with a cage design and directly overmolded plastic outer housing, which has an improved stability, without the additional outer housing material would have to be used.
  • the object is achieved by a surge arrester according to claim 1.
  • the shown surge arrester in Fig. 1 comprises two terminal blocks or end fittings 3, between which a plurality of Ableiterblöcken, for example varistor blocks 1 are arranged.
  • the varistor blocks 1 are, for example, circular cylindrical or polygonal. They are usually formed from zinc oxide with appropriate dopants.
  • the Varistor material has the property that it has a high electrical resistance below a threshold voltage, while the electrical resistance drops significantly above this threshold voltage. The transition in zinc oxide is very steep. In this way, it is possible to protect other components in a high-voltage network against overvoltage, as this overvoltage flows through the surge arrester to ground.
  • the reinforcing elements are glass fiber rods anchored in the two terminal blocks.
  • the anchoring in the terminal blocks can be ensured by wedges, by crimping, by screws or gluing or by any other suitable mounting option.
  • the terminal blocks 3 are provided with a central screws, which serves to connect the surge arrester with the high-voltage network.
  • the core of the surge arrester thus formed is equipped with an outer casing 5 with a plurality of sheds 7.
  • the outer housing houses the varistor blocks with no intervening fluid volume or voids.
  • two different screens 7 are formed along the longitudinal direction of the surge arrester, namely large diameter and small diameter screens.
  • the exact dimensions, distances and shapes of the screens depend on the intended use of the surge arrester.
  • the task of the screens 7 is, inter alia, the extension of the creepage path for the current between the two connection points of the surge arrester and the enlargement of the heat-radiating surface of the surge arrester.
  • the design of the surge arrester with two different screen sizes has proven successful, the invention is not limited thereto. It is also possible to equip the surge arrester only with a screen size, or to provide three or more different screen shapes along a surge arrester.
  • the terminal blocks 3 are largely taken up with in the outer housing 5 and encapsulated with, as in Fig. 1 is shown, with no intervening fluid volume or cavities occur here.
  • the silicone material used for the outer housing 5 is a considerable cost factor in the manufacture of surge arresters according to the invention.
  • the outer case 5 is therefore formed as thin as possible.
  • the diameter of the surge arrester in the area between two screens 7 is smaller than in the region of a terminal block. 3
  • varistor blocks 1 aluminum discs, not shown, can be inserted for better contacting.
  • a spring element may be present in the stack in order to secure the electrical contacting of the varistor blocks 1 with one another and with the end fittings 3.
  • the surge arrester furthermore has one or more stabilizing disks 25, which are arranged between two respective varistor blocks 1.
  • FIG Fig. 5 A detailed view of such a stabilizing disk 25 is shown in FIG Fig. 5 given.
  • the stabilizing disk 25 preferably made of aluminum or another suitable, highly conductive material, has a thickness that gives it sufficient stability on the other hand, however, is kept as low as possible. In a preferred embodiment of the invention, the stabilizing disc is about 5 mm thick.
  • the stabilizing disk 25 Along the circumference of the stabilizing disk 25, a number of through holes 27 are formed through which the GRP rods pass.
  • the through holes 27 are so far away from the edge of the stabilizing disk 25 that sufficient stability can be ensured.
  • the distance between the edge of each through hole 27 and the outer periphery of the stabilizing disk 25 is at least 3 mm.
  • the surge arrester thus produced exhibits excellent bending and torsional strength, making it predestined for use outdoors, even at very long lengths. In special cases, lengths of 2.5 m or more are possible, with a plurality of stabilizing disks 25 being used distributed over the length of the surge arrester as required.
  • the stabilizing disks 25 are distributed over the length of the surge arrester such that they are each arranged in the region of one of the shields 7, as shown in FIG Fig. 4 shown in detail.
  • the stabilizing plate 25 is provided according to the invention in the region of one of the screens 7, where a sufficient coverage with outer housing material is possible without the need for an additional use of material.
  • the surge arrester is made in a modular form as shown in FIG Fig. 2 and 3 is shown.
  • the modular shape allows to achieve an accurate positioning of the stabilizing discs.
  • the required number of Varistorblöcken 1 is compiled depending on the required dielectric strength of the surge arrester. Between the individual Varistorblöcken 1 can be interposed to improve the electrical contact between these blocks aluminum contact discs.
  • one or more stabilizing discs are inserted in the stack. In order to increase the overall length of the surge arrester and thus the distance between the current-carrying line and ground and for accurate positioning of the stabilizing discs 25 with respect to the screens 7 spacers made of aluminum, which correspond in shape to the Varistorblöcken 1 substantially can be provided beyond.
  • two end fittings 3 are provided. From the end fittings 3, the Varistorblöcken 1, the stabilizing discs 25 and possibly the spacers and contact discs a stack is formed.
  • disc springs or other elements may be added to the stack as needed.
  • glass-fiber reinforced plastic rods are then arranged and clamped between the end fittings 3 in order to hold the stack of varistor blocks 1 and end fittings 3 under tension.
  • the nucleus thus formed is transformed into an in Fig. 2 shown used form.
  • Fig. 2 shown shape is modular and comprises a head part 11 and a foot part 13, which correspond respectively to the two end fittings 3. Between the head part 11 and the foot part 13 a selectable number of intermediate parts 15 is provided, so that a total of a modular structure is formed.
  • the mounting plate 17 is provided with a screening, so that the distance between the head part 11 and the foot part 13 is adjustable, so that a variable number of intermediate parts 15 can be used.
  • the intermediate parts 15 contain the heating elements (not shown) necessary for the filling and crosslinking process of the silicone as well as cooling and venting channels 19 and 21.
  • the heating elements and cooling channels 19 of the individual intermediate parts 15 are provided with connections which are accessible from the outside even when the mold is assembled. In this way, an interconnection of the heating elements or the cooling channels is possible, which allows a targeted, spatially different and possibly also time-dependent tempering of the individual sections of the mold and thus can positively influence the cross-linking process of the silicone.
  • the intermediate parts 15 touch each other along the peripheral edge of a screen 7 of the outer housing 5.
  • the upper side of a screen 7 is formed by a first intermediate part
  • the underside of the same screen 7 is formed by the next following intermediate part 15.
  • Fig. 3 is the corresponding counterpart to the mold half Fig. 2 shown.
  • the in Fig. 2 and 3 shown moldings, brought together after insertion of the core, and firmly connected to each other by means of a locking device. Subsequently, the silicone elastomer is injected under pressure and crosslinked with heat.
  • the individual parameters of this crosslinking process such as the optimum temperature, the pressure required or the flow rates depend on the plastic material chosen and are known to the person skilled in the art. For example, a temperature of 50 to 300 °, preferably 80 to 150 ° C, and a pressure of 1 to 20 bar are selected.
  • the mold is again in the two in the Fig. 2 and 3 shown halves separated and removed the surge arrester. Since the silicone is still relatively elastic even in the cured state, the umbrellas easily detach from the undercuts formed by the mold.
  • a specially provided for the injection molding intermediate part 23 is provided at least in one of the two mold halves. To avoid visible injection points in the silicone housing, it is preferable to place this injection point so that it forms on the underside of a screen 7.
  • Another advantage of the described manufacturing method is that different screen shapes or screen sequences are possible, in particular special screens can be provided where stabilizing discs 25 are arranged.
  • the invention is basically not limited to the production of surge arresters with Varistorblöcken. It is also possible to produce the surge arrester with a spark gap with the method according to the invention.
  • Another advantage of the invention is that the intermediate parts 15 of the mold can be produced simply and inexpensively, for example on a turning or milling machine. In the assembly, however, undercuts are possible that are otherwise difficult or impossible to achieve in one-piece molds.
  • the glass fiber reinforced plastic rods may also be envisaged to fasten the glass fiber reinforced plastic rods to the stabilizing discs also in the longitudinal direction. This can be done for example by crimping.
