Description

Surge arrester array {SURGE ARRESTER ARRANGEMENT}

The present invention relates to a surge arrester arrangement that includes a voltage dependent impedance device that is at least partially surrounded by a housing and that can be switched by a separation device operable by a kinematic chain passing through the housing will be.

This type of surge arrester arrangement is known, for example, from the disclosure specification DE 10 2012 217 310 A1. The surge arrester arrangement of this document has a voltage dependent impedance device disposed within the housing. The voltage dependent impedance device can be switched by the isolation device, and a kinematic chain passing through the housing is used to operate the isolation device. In the case of the known surge arrester arrangement, the kinematic chain is designed in the form of a movable central rod. This ensures a simple and reliable operation of the surge arrester arrangement. However, mechanical defects in the center rod can lead to overall failure of the surge arrester arrangement. In particular, repair or replacement of the center rod requires extensive assembly work for both the housing and the detachment device.

It is therefore an object of the present invention to provide a surge arrester arrangement of the kind described in the introduction, which can be repaired in a simple manner.

According to the present invention, this object is achieved in a configuration in which, in the case of a surge arrester arrangement of the kind described in the introduction, the kinematic chain has a connection arrangement.

Surge arrester arrangements are arrangements that can be used in electrical energy transmission systems. Electrical energy transfer systems transfer electrical energy between an energy source and an energy sink. In this case, the electrical energy transmission system is designed according to the rated value. For example, an electrical insulator is designed according to the rated voltage. Overloading the electrical insulator can lead to irreparable damage. For protection purposes, the electrical energy transmission system may be provided with a so-called surge arrester arrangement, which serves to reduce or limit the so-called surge in the event of a fault, ie when the rated voltage is exceeded. To this end, the surge arrester arrangement can cause the discharge current to flow through the discharge current path if necessary. The discharge current path may be connected to ground potential, for example. The discharge current path may extend from, for example, the phase conductor to the ground potential. In this case, the discharge current path may have a voltage dependent impedance device. The magnitude of the impedance of the voltage dependent impedance device varies with the electrical voltage applied by the voltage dependent impedance device. The voltage dependent impedance device may at least partially form a discharge current path. For example, a voltage dependent impedance device may be designed as a varistor and / or have a varistor. The varistor has a rated voltage and the varistor has a low-impedance response above the rated voltage and a high-impedance response below the rated voltage. The impedance response varies with the voltage load of the voltage-dependent impedance device / varistor. In a simple case, the voltage dependent impedance device may have, for example, a controlled spark gap. It is preferred that metal oxides with voltage dependent impedance response are used in voltage dependent impedance devices. For example, a zinc oxide element is suitable which forms a permanent DC connection between the electrical potential monitored in an electrical energy transmission system (e.g., the high voltage potential of the phase conductor) and the ground potential. Leakage current can occur in this design case.

The voltage dependent impedance device is further connected to a disconnect device which can cause the voltage dependent impedance device to operate or to stop operating. The separation device may be part of the discharge current path. The voltage dependent impedance device and the separating device may preferably be electrically connected in series. The separating device can be disposed, for example, at the ground potential side end of the voltage dependent impedance device in the discharge current path. However, the separating device may be disposed at the potential side end of the discharging current path. Depending on the location of use of the drive, the drive may be placed at the same electrical potential or at different electrical potentials of the separator. If desired, the kinematic chain used to deliver the motion may have an electrical isolation section for bridging the electrical potential difference. The separating device can be preferably formed by a conventional switching device. Conventional switching devices have a contact that can be moved relative to each other and can be electrically conductive contact with each other or separate from each other. Separating devices can be used for safety purposes, for example, for surge arrester arrays. However, the isolation device may be used to disconnect the voltage dependent impedance device from the ground potential or disconnect the discharge current path and to prevent the voltage dependent impedance device from responding, for example, in the event of a test overvoltage event It may be provided for testing purposes.

The separating device can be operated by a kinematic chain. The separating device can be operated, for example, by connecting a relative movement to a switching contact of the separating device, which can be moved relative to each other. In this case, at least one of the two switching contacts may be moved to operate the switching section of the separating device. However, both of the switching contacts may be moved to generate relative motion. In this case, the separating device should be so designed that the operation of the separating device is only allowed in the substantially no-current state, that is, only in the high-impedance state of the voltage dependent impedance device. Thus, a cost effective separation device having a simple switching contact that does not need to have any additional devices for destroying switching arcs, etc. can be used.

The kinematic chain can connect one of the switching contacts that can be moved relative to each other or the switching contacts that can be moved relative to each other to the driving device and the necessary energy for causing the relative movement of the switching contacts The conversion can take place in the drive. For example, the drive can convert electrical energy into mechanical energy, and in this way the relative motion of the switching contacts of the separator can be induced. However, the shape of the energy may be transformed in any desired manner.

The connecting device can act as part of the kinematic chain. To this end, the connecting device may have, for example, a mechanical element (e.g., a shaft) that serves to transmit motion. The kinematic chain can be interrupted by a connecting device. The connecting device forms an interface in the kinematic chain.

The voltage dependent impedance device may have, for example, a varistor or a plurality of varistors connected in parallel. Therefore, the discharge current can be distributed to the plurality of varistors in accordance with the expected load capacitance. Also, each varistor may be composed of components. For example, a block (e.g., a metal oxide block) may be clamped to form a varistor, and a plurality of clamped varistors may be electrically interconnected in parallel. Regardless of the number of varistors that are electrically interconnected in parallel, the kinematic chain can be used to switch one or more varistors. The plurality of switching sections of the separating device may be preferably operated by a kinematic chain so that synchronous operation of a plurality of switching sections is also possible.

The kinematic chain can have different mechanical elements. The kinematic chain is responsible for transferring the kinetic energy from, for example, a drive to a relative contactable switching contact of the separator. In this case, the kinematic chain can pass through the walls of the housing or housing, so that the housing can form a mechanical protection barrier between the drive and the separation device. The kinematic chain linkage arrangement allows the kinematic chain members to be disassembled as needed, or the kinematic chain can be stopped or deformed as needed. For example, the drive may be changed in such a way that the structure of the separating device itself is not affected or is not required to be coupled to the interior of the housing. The connection arrangement may also be accessed outside the housing, i.e. outside the area of the housing surrounding the voltage dependent impedance device. For example, the components of the drive may be replaced in the event of failure of the drive. In this case, the protective action of the discharge current path or the voltage dependent impedance device can be maintained. In this way, the contact connection of the voltage dependent impedance device to the ground potential, in particular by the separating device, can also be maintained in the case of a kinematic chain replacement or repair.

A further advantageous improvement is that the connecting arrangement has an axis.

The shaft is a mechanical component with high stiffness, in this case capable of transmitting high forces. In addition, the shaft is convenient to mount. The shaft may also be well sealed during rotational movement. In this regard, the shaft may possibly be used to traverse the walls of the housing in a sealed manner. In this case, the axis may have a different section in the axial direction. For example, the shaft may have a section with a different cross section so that a stepped shaft is provided. In addition, at least one ball bearing, in particular a plurality of ball bearings, may be arranged in the shaft spaced apart in the axial direction, and in particular, a sealing element for radially sealing the rotational movement of the shaft is provided between two axially spaced ball bearings . In this case, preferably the diameter of the shaft may be smaller in the section of the mounting means than in the section of the radial seal. In this case, the shaft can protrude slightly beyond the wall in the transverse direction of the wall. Most of the axial range of the shaft can be disposed within the wall. As a result, the shaft can be stably mounted on the wall of the housing. Further motion and force can be transmitted at the end of the shaft.

Also advantageously, the connecting arrangement can pass through the walls of the housing in an oil-tight manner.

By passing the housing through the housing in an oil-tight manner, it is possible to prevent volatilization of the fluid by filling the housing itself with an electrically insulating fluid, especially gas, and sealing the connection arrangement. In this case, the axes of the connecting arrangement can be sealed by a radial seal, for example, to allow rotational motion of the axle in an oil-tight manner.

A further advantageous refinement may be that the connecting arrangement is connected to the gear mechanism.

The force that can be transmitted by the connecting arrangement of the kinematic chain can be increased and / or decreased by the gear mechanism. In this case, the gear mechanism may be part of the kinematic chain. Therefore, in a simple form, it is possible to reduce or increase the movement to transmit the driving movement to the switching contacts of the separating device, which can be moved relative to each other. In this case, a gear mechanism with a self-locking design can be advantageously used, so that for example the movement resulting from the switching contact can be blocked by the self-locking gear mechanism without returning to the kinematic chain. The self-locking gear mechanism used can be, for example, a worm drive mechanism or a spindle mechanism.

A further advantageous refinement may be that the connecting arrangement is connected to the clutch, in particular the full lock clutch.

The kinematic chain can be stopped or generated by the clutch. In this case, the clutch can be designed in a wide variety of ways. For example, the clutch can selectively disconnect or isolate the flow of force by a kinematic chain so that, for example, no operator control of the split switching device is possible. The clutch also allows the kinematic chain to be interrupted, for example, to replace individual components of the kinematic chain and to replace, repair, etc. the kinematic chain drive. Due to the use of the fully lockable clutch, the force can be transmitted by the kinematic chain, taking into account the shape of the coupling partner of the clutch. In this case, it may be desirable to provide a mirror-inverted configuration of the linking partner so that the drive motion can be transmitted as far as possible without slippage by the linking arrangement.

A further advantageous improvement allows the drive to be connected to the kinematic chain to be flanged-connected to the housing.

The drive may serve to introduce motion into the kinematic chain. The drive may convert one type of energy to another type of energy to cause relative motion between the switching contacts of the separating device. For example, the drive may have a crank mechanism in which rotational motion is introduced, which is eventually transmitted to the connecting arrangement, in particular to the axis of the connecting arrangement, by the clutch. The flange-connection of the drive provides an option of locking of the clutch and prevention of unwanted clutch release. For example, when designed as a full lock clutch, the clutch can be configured so that the clutch is fixed / operated when the clutch is engaged in the flange-connecting direction of the drive to the housing and the drive is fixed to the housing. As a result, the clutch can be engaged and fixed by the housing being flanged-connected to the drive.

A further advantageous refinement may be that the housing is filled with an electrically insulating fluid.

Charging the housing with an electrically insulating fluid provides an option of electrically insulating fluid selection with good electrical insulation properties. To this end, the housing may be designed as an encapsulation housing to prevent unwanted volatilization of the electrically insulating fluid disposed within the housing. The housing may be designed as a pressure vessel so that a pressure difference between the interior of the housing and the area around the housing can be generated. As a result, excessive pressure can be generated in the housing, the electrically insulating fluid can be placed under excessive pressure, and in addition, the electrical insulation resistance of the fluid can additionally be increased. The housing may be at least partially formed, for example, preferably with an electrically conductive material capable of mounting a ground potential. As a result, an electrically conductive housing can be used as a contact-forming point to form a ground point for the discharge current path. Therefore, the housing must be designed in accordance with the current capacity of the expected discharge current. However, the housing may be designed to be at least partially or completely electrically insulative. For example, electrical insulation embedding of a connection line for a voltage-dependent impedance device may be provided in the electrical insulation section of the housing, such that the high-voltage connection can be routed through the wall of the housing in an electrically insulated manner. The connection line may be part of the discharge current path. Regardless of whether the discharge current path at the high voltage side end or the ground side end, or the traversing of the kinematic chain, all cross sections of the housing are of the oil-tight type, in particular the pressure-resistant type in this case. For example, a radial sealing of the axes of the connecting arrangement, in particular, can be provided for the passage of the kinematic chained material in a pressure-resistant manner.

Suitable electrical insulating fluids are fluorine-containing media such as, for example, sulfur hexafluoride, fluoroketone, fluoronitrile, and the like. However, nitrogen, especially purified air, and carbon dioxide have also proven to be suitable. In this case, it may be desirable for the fluid to be in a gaseous state so that the fluid cleans the inner perimeter of the housing. However, the fluid may be at least partially in liquid form inside the housing.

A further advantageous refinement is that the clutch can be operated by flange-connection of the drive.

The flange-connection of the drive to the housing allows the housing and drive to be fixed relative to one another. Thus, fixed-to-each interconnections between the drive and the housing are possible. Due to these fixed-to-each interconnections, the clutch of the kinematic chain can be operated such that the movement can be transmitted by the coupling arrangement or clutch of the kinematic chain. Thus, the flange-connection of the drive device can first actuate the clutch, for example the clutch claws of the connection partner can be engaged with each other, and consequently the rotation can be transmitted by the clutch. Further, the clutch can be fixed in its connected state by flange-connection.

A further advantageous refinement allows the spindle to be adjacent to the axis at at least one end of the connecting arrangement, in particular at both ends.

The rotating spindle can displace the "nut" seated in the spindle in the axial direction. As a result, the rotational motion of the spindle can be converted into a linear motion in a simple manner. Thus, for example, it is possible to transmit a rotational motion through the housing by means of an axis, which can be converted into a lateral motion by an adjacent spindle. Thus, for example, it is possible to generate a linear relative motion between the switching contacts of the separating device. Simultaneously, the return motion or introduction of the pulsation into the kinematic chain starting from the switching contact of the separating device, for example, is blocked by the spindle. Here, the self-locking effect of the spindle is advantageous. The axis may be continuous as at least one end of the connecting arrangement, in particular as a spindle at both ends. In particular, at least one spindle may be coaxially aligned with the axis so that the spindle can be connected to the shaft at one end. In particular, a clutch may be provided on both sides of the wall of the housing for connecting the spindle to the shaft in each case. In this case, the clutches may have different designs from each other. For example, the spindle may be pinned to the shaft or otherwise connected by spring fit. In addition, the spindles and shafts can be interconnected by the claws or can be connected to each other with appropriate fit by means of a mold, for example a sleeve.

BRIEF DESCRIPTION OF THE DRAWINGS Exemplary embodiments of the invention are illustrated schematically in the drawings and described in more detail below.

Figure 1 shows a schematic cross section of a surge arrester arrangement comprising a kinematic chain.
Figure 2 shows details of the connection arrangement of the kinematic chain.

1 shows a cross section of a surge arrester arrangement. The surge arrester arrangement has a housing (1). The housing 1 is designed in the form of a hollow body, and the housing 1 has a partially electrically conductive wall and a partially electrically insulated wall. The ground potential is applied to the wall of the housing 1 formed of an electrically conductive material. In this case, the housing 1 has a hollow cylindrical structure which is oriented substantially coaxially with the main axis 2. One end of the housing 1 is formed of a disc-shaped electric insulator 3 to form an electric insulating wall. As a result, a phase conductor can be inserted into the interior of the encapsulation housing, and a direct contact with the electrically conductive wall due to a short circuit or ground potential of the electrically conductive wall is prevented, taking into account the electrical insulation effect of the electrical insulator 3. The discharge current path extends from the high-voltage potential 4 to the ground potential 5. The discharge current path has a varistor 6. The varistor 6 serves as a voltage dependent impedance device. The varistor 6 preferably has a plurality of metal oxide blocks that are axially stacked and clamped one on top of the other to achieve sufficient dielectric strength. The varistor 6 is contact-connected to the high-voltage potential 4 at one end and to the ground potential 5 at the other end. The varistor 6 is mechanically held in the housing 1 between the section of the housing 1 on which the ground potential 5 is mounted and the electrical insulator 3.

The separator 7 is disposed on the ground-potential side in the discharge current path between the varistor 6 and the ground potential 5. Alternatively, the separating device 7 may be located at the opposite end of the varistor 6. In this case, it may be necessary to design the section of the kinematic chain to operate the separating device 7 in a seasonally insulated manner in order to avoid a short circuit of the varistor 6. The separator 7 allows the discharge current path to be interrupted. To this end, the separating device 7 has a movable contactor 8. In this case, the movable contactor 8 is configured in the form of a bolt and is disposed substantially coaxial with the main axis 2. [ In addition, the movable contact member 8 is mounted so as to be displaceable in the axial direction with respect to the main axis 2. [ To this end, a contact carrier 9 is provided and the contact carrier is electrically conductively connected to the section of the housing 1 on which the ground potential 5 is mounted, in particular to the section of the housing 1 do. The movable contactor 8 is routed in an axially displaceable manner and the ground potential 5 is permanently applied thereto by the sliding bushing of the contact carrier 9. [ The separating device 7 further has a stationary contactor 10. In this case, the stationary contact body 10 is designed in the form of a bush, and the bushing opening is configured in a complementary shape to the movable contact body 8. The stationary contact member 10 is connected to the ground potential side end of the varistor 6 and is positioned in an electrically insulated manner with respect to the section of the housing 1 on which the ground potential 5 is mounted. The ground potential can be applied to the stationary contactor 10 only by the contact made by the switching section of the separating device between the two contacts 8, 10 or by the bridging of the switching section. The opening of the switching section between the contact bodies 8, 10 leads to the electrically insulating arrangement of the stationary contact 10. In this state, the stationary contact member 10 assumes a so-called floating, that is, an unformed electric potential state.

A drive device (11) is provided for generating a drive motion of the movable contactor (8). The drive device (11) is flange-connected to the housing (1). The drive device 11 serves to connect the motion to a kinematic chain that transmits the motion from the drive device 11 to the movable contactor 8. [ To this end, the kinematic chain has a connecting arrangement (12). The configuration of the connection arrangement 12 will be described in more detail with reference to Fig. The connecting arrangement 12 has a rotatable shaft 13 which passes through the wall of the housing 1. In order to integrate the connecting arrangement 12 into the kinematic chain, respective clutches 14a and 14b are provided on both sides of the wall of the housing 1 through which the connecting arrangement passes. In this case, the kinematic chain has a first spindle 15 which is connected to the rotatable shaft 13 by the clutch 14b in the housing 1. [ The second spindle 16 is connected to the rotatable shaft 13 by the clutch 14a outside the housing 1. [ The two spindles 15, 16 are arranged in an aligned manner. Likewise, the two spindles 15, 16 are aligned and positioned with respect to the rotatable shaft 13. The spindles 15 and 16 are connected to the rotatable shaft 13 at mutually opposite ends of the shaft 13 and the spindles 15 and 16, either inside or outside the housing 1.

The first spindle 15 projects into the threaded portion of the movable contact member 8 which is prevented from rotation. As a result, when the first spindle 15 rotates, the rotational motion of the first spindle 15 is converted into a linear motion of the movable contactor 8. [ The operation of the kinematic chain is enabled by the second spindle 16 with the use of a hand crank 17. To this end, the second spindle 16 is rotated by the use of the hand crank 17, and the rotational motion can be transmitted to the rotatable shaft 13 by the clutch 14a, To the first spindle 15, as shown in Fig.

A switching interlocking portion 18 which is guided displaceably in the axial direction on the second spindle 16 is moved in synchronism with the movement of the movable contactor 8. [ As a result, it is possible to map the state or relative position of the movable contactor 8 with respect to the drive device 11. [

Hereinafter, the design of the connection arrangement 12 will be described in principle with reference to FIG. To this end, Fig. 2 shows a cross section of the drive device 11 as is known from Fig. Thus, the rotatable shaft 13 of the connecting arrangement 12 is also shown in cross-section. The length of the rotatable shaft 13 substantially corresponds to the thickness of the wall of the housing 1 through which the rotatable shaft 13 passes. Thus, the rotatable shaft 13 protrudes slightly beyond the entrance opening of the recess in the wall of the housing 1 through which the shaft passes. In this case, the rotatable shaft 13 has a plurality of sections, and the intermediate section 19 of a relatively large diameter lies next to two sections of relatively small diameter. The intermediate section 19 is radially surrounded by two axially spaced seals 20. The two sealing elements 20 serve to seal the intermediate section 19 in the radial direction from the inner casing side surface of the preferred circular cylindrical recess of the complementary shape of the wall of the housing 1. Therefore, it is ensured that the shaft 13 is radially sealed from the housing 1. The radial sealing means may preferably be of an internal pressure design. The arrangement of the ball bearings 21 is of a relatively small diameter and is provided in each of the sections of the shaft 13 adjacent to the intermediate section 19. The shaft 13 can be guided and supported in the housing 1 separately from the additional elements of the kinematic chain by means of the ball bearing 21.

The first spindle 15 or the second spindle 16 is connected to the respective end sides of the rotatable shaft 13. The two spindles 15 and 16 are connected to the rotatable shaft 13 by the clutches 14a and 14b, respectively. The two clutches 14a and 14b have different designs in this case. The clutch 14a that serves to connect the rotatable shaft 13 to the second spindle 16 includes a sleeve type coupling element 14a which is fitted to the second spindle 16 or the rotatable shaft 13 in a complementary shape, With the result that a mutual locking interconnection is formed between the second spindle 16 and the rotatable shaft 13 by means of the sleeve-like connecting element. Alternatively, the clutch 14a may be designed in the form of, for example, spring fitting, press fitting, or the like.

The first spindle 15 is rotatably supported on the rotatable shaft 13 by a pinning arrangement by a transverse bolt passing through a section of the first spindle 15 protruding in a complementary shape on the end side of the rotatable shaft 13. [ Lt; / RTI > In this case, the position of the pin is chosen such that the pin lies in the region of the section adjacent to the intermediate section 19 of the first axis 13, and the pin is engaged with the ball bearing 21 in the radial direction Is prevented.

The concave portion of the wall of the housing 1, which accommodates the rotatable shaft 13 of the connecting arrangement 12, is formed so that the protruding shoulder is disposed inward in the flange-connecting direction of the drive device 11, A ball bearing (21) securing a pin fixing arrangement is formed to be axially supported with respect to the shoulder. As a result, the sealing body 20 and also the other ball bearings 21 are also indirectly pressed against the protruding shoulders. To this end, the drive device 11 has a flange-connecting plate 22. The flange-connecting plate 22 has a central recess with a pressing shoulder 23. The pressing shoulder 23 is designed in a radially circumferential design and acts on the ball bearing 21 so that the other shoulder 21 against the shoulder which inwardly protrudes inwardly in the wall of the housing 1 by means of the intermediate section 19 ). The flange-connecting plate 22 is urged against the housing 1 by means of corresponding bolt connecting means 24. Thus, the connecting arrangement 12 is fixed to the wall of the housing 1 through which the kinematic chain is passed. The clutches 14a and 14b are fixed by flange-connection.

In this way a connecting arrangement 12 is provided and the clutches 14a and 14b of the connecting arrangement are fixed by flange-connection of the driving device 11. [

The second spindle 16 is connected to the rotatable shaft 13 by a clutch 14a. In order to improve the mounting of the second spindle 16, a guiding element 25 coaxially oriented with the main axis 2 is fitted in the flange-connecting plate 22. The guiding element 25 is configured, for example, as a hollow cylinder. However, for example, a plurality of stud bolts distributed around the main axis 2 may perform similar functions. The guiding element 25 serves to form a connecting point 26 for fastening the latch 27. The latch 27 surrounds the guide element 25 and thus surrounds the second spindle 16 on the outer casing side and forms a bearing bush 28 for the second spindle 16. [ Two ball bearings are disposed in the bearing bush 28 of the latch 27.

The sliding interlocking portion 30 is displaceably disposed on the second spindle 16. [ Since the sliding interlocking portion 30 is displaceably mounted on the guiding element 25 in a rotationally fixed manner, the sliding interlocking portion 30 is displaced in the axial direction when the second spindle 16 rotates. In this case, the position of the sliding interlocking part 30 on the second spindle 16 is synchronized with the relative position of the movable contact body 8 inside the housing 1. The signal transmission contacts thus provide a signal to the position of the movable contact 8 and thus to the switching state for the separating device 7, Signaling the position of the indicator. In this case, the signal transferring contacts 31, 32 are provided with corresponding contact points which are electrically bridged when the sliding interlocking portion 30 passes. As a result, for example, the switching state of the separating device 7 can be signaled to the control room.

In addition, a local indication of the switching state of the separating device 7 can be provided to the driving device 11 itself. To this end, the recesses 33, 34, which can visually detect the position of the sliding interlocking portion 30, can be provided on the guide element 25 or the latch 27, for example. Therefore, in order to allow a high-contrast local indication of the switching state of the separating device 7, the sliding interlocking part 30 may be provided with a color mark in the area of the recesses 33 and 34.
