Definitions
- the invention relates to a fast disconnecting device for surge arresters, in particular disc-shaped or planar varistors, with at least one held under a mechanical bias element and a separation point to separate the surge arrester under thermal overload from the respective network, the separation point against each other has variable position contacts and one this contacts is executed fixed, according to the preamble of claim 1.
- Cut-off devices of conventional high-performance surge arresters with I n > 15 kA 8/20 ⁇ s with varistors for use in low-voltage networks generally have a solder joint which serves as a thermal separation point, a movable connection which is under mechanical prestressing and a constriction zone which is reached when it reaches it of its melting integral adiabatically melts.
- the solder connection of the movable connection part establishes the connection to the varistor connection and assumes the function of the thermal separation point, which disconnects it from the network when the varistor overheats.
- Typical such separation devices are shown, for example, in DE 42 41 311 A1 or DE 38 05 889 A1.
- the Lotstelle connects two metal parts, which have a more or less high heat conduction and a fairly high heat capacity, due to the fact that these metal parts must control all occurring current loads in the working area of the arrester.
- the solder joint itself must meet the requirements of the pulse current carrying capacity.
- the solder joint is permanently exposed to the mechanical stress of the spring bias, which prevails on the moving part of a corresponding feeder.
- the varistor is already overloaded before a thermal separation takes place.
- an overload of the varistor can lead to undefined relationships with regard to the resulting fault currents and thus to a large number of different errors and further damage.
- WO 2004/064213 A1 shows an arrangement in which a bimetal locks a switching contact.
- the bimetal is not flowed through by the current.
- the movement of the bimetal releases the lock and disconnects the varistor from the mains.
- the indirect heating via the electrical connection lines of the varistor, the geometrical arrangement, the material properties and the compulsory dimensions of the bimetal exclude a very short reaction time to the contact opening from a physical-constructive point of view.
- the object of the invention is therefore to provide a rapid separation device for surge arrester, in particular disk-shaped or planar varistors, wherein the separating device is to be effective even before reaching a critical temperature or overloading of the varistor and beyond to realize it with simple means.
- the separating device is to be effective even before reaching a critical temperature or overloading of the varistor and beyond to realize it with simple means.
- the core idea of the invention is accordingly based on physically and functionally separating the function-bearing parts for the thermal release function of the separating device from the current-carrying connecting parts. This allows an optimization of the thermal tripping function, whereby significantly shorter tripping times can be achieved.
- the respective surge arrester can therefore be safely disconnected from the mains in the event of a large number of faulty cases before it is destroyed or overloaded.
- a fast disconnecting device for surge arresters in particular disk-shaped or flat varistors, is assumed to have at least one element held under a prestress, in particular a mechanical pretension, wherein a disconnection point is furthermore provided in order to protect the surge arrester from thermal overloading to separate from the respective network, wherein the separation point against each other has positionally variable contacts and wherein one of these contacts is carried out fixed.
- the contact-variable contacts are electrically connected in a solderless manner so that occurring current forces predominantly act in the direction of the contact force, but are at least not oriented against this contact force.
- the movable of the position-variable contacts is from a thermally releasable located on the surge arrester, lost element from a closed to a detachable transferred position.
- the lost element is acted upon by the element under mechanical prestressing.
- the lost element may be implemented as a thermally activatable pin, block or pin which secures the solderless held contacts.
- the bolt, the block or the pin is connected at one point to the overvoltage arrester via a thermally detachable means, which is to be expected at an early stage and at most with a heating in case of overload.
- the lost element and / or its fasteners have only a low heat capacity and low thermal conductivity. Due to the low heat capacity and the low thermal conductivity of the lost element or its attachment means, the solder is not unnecessarily cooled as a temperature sensitive mounting material. The heat generated in the varistor is therefore used almost exclusively and directly for heating the very low solder mass, so that very fast reaction times can be ensured here.
- the lost element is held immediately under spring bias and secured to the surge arrester with a thermally sensitive means.
- the lost element using the spring force bias, directly or indirectly actuates the movable contact to effect the disconnect condition.
- the position of the movable contact is changeable from a severance position to a reclosed position, i. H. there is reversibility here.
- a thermally sensitive area or section may be provided to achieve mechanical separation of a part of the bolt, block or pin.
- a force-enhancing arrangement in particular a lever mechanism can be provided.
- an electrical connection to other extinguishing devices such. B. arc guide, provided.
- Figure 1 is a schematic representation of a first embodiment of the invention with a fixed on a thermally sensitive means on the varistor lost element.
- Fig. 2 shows an embodiment similar to that of FIG. 1 with a terminal contact and Fig. 3 shows two states of a quick disconnecting device (closed and open), wherein the lost element acts either similar to a bullet on the movable contact piece or via a force-transmitting arrangement (not shown).
- varistors have areas with different heating due to the installation situation, the material structure, the geometry and their contacting of the contact sheets and due to the current distribution.
- the point of the strongest heating is to be selected for the positioning of the thermally-dissolvable agent.
- the thermally releasable agent or the part fixed hereby is to be formed in direct contact with the varistor so that the lowest possible heat capacity is available and also the heat dissipation is reduced.
- the avoidance of influencing the heating of the selected positioning by unwanted heat dissipation ensures the desired fastest possible temperature-sensitive separation of the varistor and thus optimal adaptation to its protection.
- the response temperature of the thermally dissolvable agent is as close as possible to the temperature which is reached at the varistor under normal operating conditions.
- the movable contact piece is subjected to an appropriate spring preload.
- the connection of the movable contact piece with the varistor is carried out according to the invention via a loose, unsoldered contact or terminal point.
- connection should not have any significant effect on the residual voltage and thus the protection level to have. Furthermore, the connection should be designed so that it does not weld at surge loads, so that the strength of the connection is well below the force that is available for the movement due to the spring preload.
- An advantage of the configuration of such a contact point is when the direction of the current forces occurring at surge load does not act against the contact force.
- thermally sensitive part or material is attached on the surface of the varistor with the highest heating.
- This part should be as small as possible and have the lowest possible heat capacity.
- the hottest point of the varistor can be influenced by the design of the varistor body as well as the choice of material and the geometry of the contact plate in their position.
- the thermally sensitive part thus serves to secure the lost element and even has a negligible volume or so only a small mass in relation to the varistor, in a range of ⁇ 10 mg.
- the thermally sensitive part assumes the same temperature as the varistor, virtually without time delay.
- the lost element has only a very small heat capacity and low heat conduction, so that no appreciable temperature gradient arises between the solder and the varistor.
- the contact surfaces can be influenced by the explained choice of materials (different thermal conductivity in the axial and radial direction or geometry - creation of heat traps) the heat flux density and thus the location of the area of maximum warming.
- Waxes, adhesives, solders or other materials which have a melting point or a softening temperature just above the usual operating temperature of the varistor are suitable for fixing.
- an additional defined spring force preferably vertical to the force acting on the movable connection spring force can be used at the fixed terminal of the varistor, so that the necessary force for the contact connection is present at all times.
- this area z. B. also within the separation blocking part, d. H. the bolt, block or pin provided or attached.
- the heat conduction is optimized up to this functional area, but the heat capacity is kept to a minimum.
- the separation-blocking part is pushed aside or pushed aside by the spring force. It is envisaged that the now loose, lost part does not hinder the separation. This can be assisted by suitable guides (not shown in the figures).
- the blocking part can also be performed, for example, as an eccentric element, so that when reaching the melting temperature of the temperature-sensitive area of this part, z. B. by the applied spring force is moved around a fixed pivot point and thus releases the movable contact.
- eccentric parts can simultaneously means for increasing the insulation resistance and increasing the switching capacity of the separating device, for. B. be used in the form of insulation films or insulation tubes. Such insulation parts can be performed separately, for example, but also be attached directly to the movable switching contact.
- a varistor disk 1 has outer terminals 7.
- a first varistor contact 6 represents one of the separation point forming, against each other position-variable contacts.
- the movable part 8 of the position-variable contacts is applied to the varistor contact 6.
- the contacts 6 and 8 are secured by a lost element 11.
- This lost element 11 is connected to the varistor surface via a thermally releasable means.
- a constriction 4 may be formed in the contact bracket 3, which communicates with the outer terminal 7 via a line 9.
- a spring force F acts on the contact clip 3, wherein an undesired shift in position of the contacts 6 and 8 is excluded in normal operation by the lost element 11.
- the mutually movable contacts 6 and 8 are solderless standing in electrical connection and designed so that occurring current forces predominantly act in the direction of the contact force (not shown in Fig. 1).
- the connection of the lost element 11 to the surface of the varistor 1 is released.
- the stop action by the lost part 11 is eliminated and it can move the movable part 8 of the contacts in the direction of the released force vector, so that the desired separation state is realized.
- FIG. 2 A similar, but three-dimensional representation of an embodiment of the invention is shown in FIG. 2.
- the direction of movement of the lost element 11 is symbolized here by an arrow.
- the movable part 8 of the contacts is here contacted by a symbolically indicated clamping pocket 10 solderless.
- this mechanical Mitschinition stand is realized so that in a detachment of the lost element 11, the separation movement in the direction of the force F can be done without interference.
- FIG. 3 is again assumed by a varistor 1, which has two varistor terminals 6 and 7.
- the varistor connection 6 is connected to the mains via the separating device, comprising the means 3, 4 and 10.
- a non-conductive thread or wire 13 is provided, which consists of a material with high strength and low thermal expansion.
- the thread 13 is attached directly or indirectly to the varistor with the aid of a temperature-sensitive substance 12. This substance blocked in the illustration shown in FIG. 3 on the left side directly Force of the spring 14 or a part of this, wherein the spring 14, the lost element 11 is acted upon by a biasing force F.
- the contact clip 3 can be made pivotable about an axis, as indicated by the circular arrow representation.
- the presented embodiments can reliably protect varistors from destruction even at high power-frequency overvoltages.
- the wire or thread can also be made conductive.
- the wire serves as an electrode, which is destructible by the thermal effect of the arc, so that even in this case, the separating device safely opens.
