Device for mounting on power busbars comprising a switch and an electronic component

Description

[0001] The present invention relates to a device for arrangement on power busbars comprising a switching device and an electronic component.

[0002] Switching devices, in particular electrical load switches, especially those with fuses, are used, for example, in industrial and power plant applications both as busbar feed-in switches and as outgoing switches for switching highly inductive loads (e.g. motors) including overload protection.

[0003] The switching device according to the invention is, in particular, a switching device that covers a current range in which cylindrical fuses are used, for example D0 fuses. The switching device according to the invention can be used, for example, as a pre-fuse for DIN rail-mounted devices, as a protective device for drives in production facilities and / or in photovoltaic installations.

[0004] Switching devices, which are typically used for power distribution, are subject to increasingly stringent requirements. In particular, it is stipulated that switching devices must be equipped with electronic components for data acquisition and processing, for example, to continuously monitor or measure all current and voltage-related data and / or to monitor electrical fuses and their condition integrated into the switching device, or to monitor the switching state of the switching device itself.

[0005] From DE 297 05 224 U1, a device for installation on busbars is known, wherein this device comprises an NH fuse or NH switch disconnector and a device carrier strip. Furthermore, the device includes a transducer wired to a sensor or a terminal block / connector strip. The separate device carrier strip accommodates the transducer, and the terminal block / connector strip or the sensor is associated with the device carrier strip. The device carrier strip is arranged between the busbars and the switching device, with the switching device being mounted on the device carrier strip. As a result, the device requires more installation space in the vertical direction than the switching device itself. A separate sensor can be mounted on the device.

[0006] DE 10 2017 011 374 A1 discloses a device for arrangement on busbars comprising a switching device and an electronic component, which discloses the features of the preamble of claim 1. EP 3 671 786 A1 and EP 1 271 583 A2 disclose further prior art.

[0007] The object of the present invention is to provide a device for mounting on busbars, comprising a switching device and an electronic component, which is characterized by particularly simple handling and, furthermore, by a particularly small and / or space-saving installation requirement. A further object of the invention is to provide a device comprising a switching device and an electronic component in which a particularly simple and quick replacement or retrofitting of an existing switching device with an electronic component is possible. These objects are achieved by a device comprising the features of claim 1. Advantageous embodiments are the subject of the dependent claims.

[0008] The device according to the invention for mounting on busbars comprises a switching device and an electronic component. The switching device is, in particular, a fuse strip or a load switching strip. The switching device has a front face facing away from the busbars and mounting areas for fuses arranged longitudinally along the switching device. The mounting areas for the fuses are specifically designed to accommodate a cylindrical fuse, particularly a D0 fuse. Each mounting area is associated with an input conductor and an output conductor. When a fuse is installed in the mounting area, the input conductor and the output conductor are electrically connected to each other, and the fuse interrupts the electrical connection between the input conductor and the output conductor in the event of an overcurrent.

[0009] The switching device also has a housing with a longitudinally extending side wall, with the electronic component being mounted in the side wall.

[0010] This arrangement of the electronic component in the side wall of the switching device has the advantage that the device has a particularly favorable installation space requirement; in particular, the switching device does not require any additional installation space due to the additional electronic component in the longitudinal direction of the switching device or in any vertical direction. Specifically, it is intended that the installation space requirement of the device is either not increased at all compared to the installation space requirement of the switching device itself, or only increased in the transverse direction of the switching device, i.e., in the area of ​​the side wall in or on which the electronic component is mounted.

[0011] It is intended that the electronic component is detachably connected to the side wall in the area of ​​an outer side of the side wall, in particular that the electronic component can be plugged onto the side wall from the outside.

[0012] Preferably, the electronic component is attached in a transverse direction to the switching device.

[0013] The electronic component is used in particular for current measurement and / or voltage measurement and / or energy measurement and / or power measurement and / or fuse monitoring.

[0014] The mounting areas are primarily intended for the front-facing mounting of fuses.

[0015] It is provided that at least one of the input conductors and / or at least one of the output conductors has a section that protrudes towards the side wall compared to the other sections of the input conductor or output conductor. This is particularly advantageous with regard to the design of the electronic component, especially any sensor components of the electronic component, such as a Hall sensor, and / or the design of voltage taps of the electronic component, since this design of the input conductor or output conductor places a portion of the conductor particularly close to the side wall, thus simplifying measurements on this conductor and / or contacting this conductor with the electronic component, as the distance between the electronic component and the section of the conductor is particularly small there.Furthermore, it is particularly advantageous with regard to current measurement using a Hall sensor if the current-carrying component used for current measurement using the Hall sensor is arranged particularly close to the Hall sensor in order to obtain particularly accurate measured values ​​and, in particular, to minimize interference fields that negatively affect the accuracy of the measurement.

[0016] For the same reason, it is considered particularly advantageous if at least one of the input current conductors and / or at least one of the output current conductors has a plate-shaped section, wherein the plate-shaped section is designed such that a main expansion surface of the plate-shaped section faces the side wall. Preferably, the main expansion surface of the plate-shaped section runs parallel to the side wall. It is considered particularly advantageous if the plate-shaped section forms the projecting section.

[0017] With regard to minimizing the influence of interference fields during current measurement using a Hall sensor, it is considered particularly advantageous if the electronic component and / or the switching device has a shielding plate, wherein this shielding plate is arranged in the area of ​​the Hall sensor of the electronic component in order to shield it from interference fields.

[0018] It is provided that at least one of the incoming current conductors and / or at least one of the outgoing current conductors has a U-shaped intermediate section with two legs and a web connecting these two legs, the legs facing away from the side wall. The web forms the protruding section and / or the plate-shaped section.

[0019] Preferably, the side wall has a bearing structure on its outer surface for supporting the electronic component. This bearing structure can be, for example, a mounting area or insertion area onto which the electronic component is mounted or into which it is inserted.

[0020] The bearing structure is primarily a recess, in which the electronic component is mounted. However, it is also conceivable that the side wall has externally accessible receiving areas for fasteners on its outer surface, for example, a thread, particularly a screw boss, for receiving a screw, with this screw serving to fasten the electronic component to the side wall of the switching device.

[0021] With regard to a particularly small installation space requirement, it is considered advantageous if the side wall of the housing has a recess, the recess accommodating the electronic component, preferably completely. It is considered particularly advantageous if the side wall has a number of recesses corresponding to the number of mounting areas, with each recess accommodating an electronic component. In such a design with multiple recesses, it is quite conceivable that not every recess is fitted with an electronic component, for example, if only one of the multiple mounting areas or its fuses is to be monitored.

[0022] For a particularly advantageous design of the measurement using the electronic component, it is considered beneficial if the plate-shaped section and / or the protruding section adjoins the side wall in the recessed area. The arrangement in the recessed area has the advantage that, due to its placement in the recess, the electronic component is positioned particularly close to the current-carrying components of the switching device, especially closer to the current-carrying components than if the electronic component were not arranged in a recessed area. For example, a Hall sensor of the electronic component can be arranged in the recessed area in this way, so that the Hall sensor is positioned particularly close to the current-carrying component, such as the input or output conductor.

[0023] It is considered particularly advantageous in terms of cost-effective manufacturing and low space requirements if the electronic component does not have a separate housing.

[0024] Particularly in an embodiment without a separate electronics housing, it is considered advantageous if the electronic component comprises a circuit board or printed circuit board, especially a measuring circuit board, wherein the circuit board mechanically interacts with the side wall to mount the electronic component in the side wall. Preferably, the circuit board is mounted in the recess of the side wall, especially in a snap-fit ​​manner.

[0025] Regarding the locking mechanism of the electronic component, it is quite conceivable that the side wall and / or the electronic component itself has locking elements. The locking elements of the side wall could, for example, be an outwardly projecting, elastically deformable locking projection, whereby the locking projection engages the electronic component, in particular the circuit board, in the locking position on a side facing away from the switching device.

[0026] Preferably, the locking device can be released from the outside of the switching device to allow easy removal of the electronic component from the side wall.

[0027] To achieve a particularly simple and reliable connection between a current-carrying component of the switching device and the electronic component, it is considered advantageous if the electronic component has at least one contact element, wherein the respective contact element extends through the side wall. This eliminates the need for complex wiring and similar components. The contact is preferably made during the mechanical connection of the electronic component to the switching device. It is considered particularly advantageous if the contact element is designed as a spring contact and / or has a spring contact.

[0028] Preferably, the respective contacting element contacts one of the input current conductors and / or one of the output current conductors.

[0029] In an embodiment of the invention in which the electronic component is arranged entirely within the respective recess, the electronic component is, in particular, an electronic component used for fuse monitoring. Such fuse monitoring devices can be designed to be particularly simple, thus requiring very little installation space. For example, it is conceivable that such an electronic component for fuse monitoring is essentially formed by having two contact elements, one of which contacts the input current conductor and the other of which contacts the output current conductor of the respective receiving area, the two contact elements forming a closed circuit with a light-emitting diode, and the electrical circuit having a high resistance.With a functioning fuse, only a very small current flows through the electronic component's circuit, so the LED does not light up or does not glow noticeably. If the fuse blows, a current flows through the electronic component's circuit sufficient to cause the LED to glow noticeably.

[0030] Accordingly, a lit diode indicates that the fuse has tripped.

[0031] Particularly with more complex electronic components, especially those incorporating current, voltage, and / or energy measurement components, it is considered advantageous for the electronic component to have a separate electronic housing, wherein the electronic housing is mounted in the side wall of the switching device housing. Preferably, the electronic housing is clamped and / or snapped into place within the housing. Preferably, the electronic housing is detachably mounted within the switching device housing.

[0032] It is considered particularly advantageous if the electronics housing is open on the side facing the switching device. This allows the electronics of the component to be positioned very close to the side wall of the housing.

[0033] Preferably, the electronics housing protrudes laterally from the side wall. In particular, it is provided that the electronics housing is flush with the housing of the switching device in the vertical and / or longitudinal direction.

[0034] It is quite conceivable that the electronics housing has ventilation openings, especially ventilation slots.

[0035] In an embodiment with an electronics housing, it is considered particularly advantageous if the electronic component comprises a circuit board or printed circuit board, with the electronics housing accommodating the circuit board. The circuit board is, in particular, a measuring circuit board. It is considered especially advantageous if the circuit board extends over all the mounting areas for fuses of the switching device.

[0036] To ensure a particularly high level of safety, it is considered advantageous if the side wall of the switching device housing is designed to be finger-safe. This makes it possible to use the switching device even without any attached electronic components, while still guaranteeing the necessary safety for the operator.

[0037] It is considered particularly advantageous if the electronic housing is also finger-safe when connected to the switching device. Furthermore, it is considered particularly advantageous if, in an embodiment of the electronic component without an electronic housing, the electronic component mounted in the side wall, in particular the circuit board, is finger-safe.

[0038] Furthermore, it is considered particularly advantageous if through-holes formed in the side wall, for example through-holes for the contacting elements of the electronic component, are designed to be finger-safe.

[0039] To achieve finger safety even without an electronic component, it is quite conceivable that a dummy is used instead of the electronic component.

[0040] The electronic component is designed to include a device for measuring the current flowing through the input conductor and / or the output conductor and / or the voltage applied to the input conductor and / or output conductor. Furthermore, it is considered advantageous if the electronic component has a voltage tap for measuring the voltage applied to the input conductor and / or the output conductor. It is conceivable that the voltage tap serves to supply the electronic component with current or voltage. Preferably, the electronic component includes a fuse monitoring device.

[0041] It is considered particularly advantageous if the device for measuring the current flowing through the input and / or output current conductor includes a Hall sensor. The Hall sensor allows for contactless current measurement. Preferably, the Hall sensor is mounted in a recess in the side wall.

[0042] It is considered particularly advantageous if the electronic component has at least one indicator, for example a light-emitting diode, which is visible from the front of the switching device. This indicator can, for example, serve to show the status of the electrical fuse located in the receiving area.

[0043] To allow visibility of the display from the front, it is quite conceivable that the housing wall and / or any front cover of the switching device and / or the electronic housing of the electronic component has a viewing window or a recess.

[0044] The electronic component preferably has an externally accessible communication interface. Preferably, the communication interface is a hardware interface. For example, the communication interface could be a Modbus / RTU interface, a Modbus / TCP / IP interface, a CAN bus interface, an Ethernet interface, or a Profinet interface. It is considered particularly advantageous if the interface is accessible from the front of the switching device and / or from an end face of the switching device.

[0045] It is quite conceivable that the electronic component has a connection for an external power supply.

[0046] It is considered particularly advantageous if the switching device has a number of fuse mounting areas corresponding to the number of busbars.

[0048] The Figs. 1 to 5Figure 1 shows a switching device 1 for installation on busbars 3 of a busbar system, wherein the switching device 1 has a number of receiving areas 6 corresponding to the number of busbars 3 for the front-facing receipt of cylindrical fuses (not shown in detail), in this case D0 fuses, wherein the receiving areas 6 are arranged in a row along a longitudinal direction X of the switching device 1. Each receiving area 6 is associated with an incoming current conductor 7 and an outgoing current conductor 8. The switching device 1 has a front side 4 facing away from the busbars 3 and a rear side 5 facing the busbars 3. The switching device 1 has two opposing, parallel side walls 11, 12, wherein the second side wall 12 is essentially flat, whereas the first side wall 11 has three recesses 18.The switching device 1 has a housing with two housing parts 9, 10, wherein housing part 9 forms the first side wall 11 and housing part 10 forms the second side wall 12. The two side walls 11, 12 extend substantially in the longitudinal direction X and in the vertical direction Z and perpendicular to a transverse direction Y of the switching device 1. The switching device 1 also has a front cover 13 pivotably mounted in the housing 9, 10 for covering the three receiving areas 6 from the front. Furthermore, the switching device 1 has a manually operable actuating lever 14, which serves to switch the switching device 1. The actuating lever 14 interacts with a snap-action mechanism (not shown in detail), which in turn interacts with a slide 31 mounted in the housing 9, 10, which serves to switch switching contacts of the switching device 1.For this purpose, bridge contacts 15 are mounted in the slider, these bridge contacts 15 being spaced apart from busbar contacts 16, which serve to connect the busbars 3, when the switching device 1 is switched off. Furthermore, the bridge contacts 15 are spaced apart from the respective input conductor 7 in the switched-off position. This state is in the . Fig. 5As shown, when the switching device 1 is switched on, the slider 31 is moved such that the respective bridge contact 15 contacts both the busbar contact 16 and the input conductor 7. In this state, voltage is therefore present on the input conductor 7 and on any electrical fuse located in the receiving area 6. If a load is connected to the output conductor 8, current flows from the corresponding busbar 3 via the busbar contact 16, the bridge contact 15, the input conductor 7, the electrical fuse, and the output conductor 8 to the load.

[0049] In the Fig. 6 and 7In the first embodiment of the device according to the invention, the device has, in addition to the switching device 1, three separate electronic components 2, wherein the three electronic components 2 are mounted in a locking manner in the respective recess 18 of the side wall 11.

[0050] The electronic component 2 comprises a measuring circuit board 17, on which a display element 28 in the form of a light-emitting diode and two contact elements 21 in the form of spring contacts are attached. As can be seen in particular from the Fig. 8 As can be seen, the contacting elements 21 penetrate through openings 20 in the side wall 11 of the switching device 1 and contact the input current conductor 7 and the output current conductor 8 of the respective receiving area 6. In the Fig. 6 and 7In the illustrated embodiment of the device, the electronic component 2 is a fuse monitor, and the indicator 28 lights up when the electrical fuse is tripped. To allow the LED 28 to be visible from the front 4 of the switching device 1, both the housing part 9 and the front cover 4 have recesses 29 in the area of ​​the indicator 28.

[0051] As in particular the Fig. 6 As can be seen, the respective electronic component 2 is completely arranged within the recess 18, so that the extension of the device in the transverse direction Y is not increased compared to the extension of the switching device 1 in the transverse direction Y.

[0052] As in particular the Fig. 7 As can be seen, the electronic components 2 can be attached from the outside to the side wall 11 in the direction of arrow 32, thus in the transverse direction Y.

[0053] As in particular the Fig. 6As can be seen, the side wall 11 has elastically deformable locking elements 19 in the area of ​​the recesses 18, wherein these locking elements 19 engage the electronic component 2, namely the circuit board 17, on a side of the circuit board 17 facing away from the switching device 1. Thus, the electronic components 2 can be connected to the switching device 1 without tools.

[0054] The Figs. 10 to 16 Figure 1 shows a second embodiment of the device, wherein the switching device 1 in this embodiment is identical to the switching device 1 in the first embodiment. Accordingly, different electronic components 2 can be connected to one and the same switching device 1.

[0055] In the second embodiment, the electronic component 2 enables, in addition to fuse monitoring, the measurement of the current flowing through the respective input conductor 7. For this purpose, the electronic component 2 has a circuit board 17 extending over all three recording areas 6, wherein this circuit board 17 is equipped with two contact elements 21 and a Hall sensor 23 for each of the three recording areas 6. The contact elements 21, in turn, serve to connect the respective input conductor 7 and the respective output conductor 8 for fuse monitoring. The Hall sensor 23 serves to measure the current flowing through the input conductor 7, wherein the respective Hall sensor 23 is additionally shielded by a shielding plate 22 to shield against interference fields.

[0056] To improve the accuracy of the current measurement, the input current conductor 7 has a plate-shaped section 24 projecting towards the side wall 11 compared to the other sections of the input current conductor 7. The plate-shaped section 24 is designed such that a main expansion surface of the plate-shaped section 24 faces the side wall 11, and in this case, the plate-shaped section 24, or rather its main expansion surface, runs parallel to the side wall 11. The projecting, plate-shaped section 24 abuts the side wall 11 in the region of the recess 18, and the Hall sensor 23 also abuts the recess 18 in the transverse direction Y, thus positioning the Hall sensor 23 particularly close to the plate-shaped section 24. This has a particularly favorable effect on the accuracy of the current measurement.

[0057] The Fig. 9Figure 1 shows the input conductor 7 in a perspective view. A sheet metal development of the input conductor 7 is essentially S-shaped.

[0058] The electronic component 2 also has a communication interface 26 attached to the circuit board 17.

[0059] During the Figs. 10 to 16 In the illustrated embodiment, the electronic component 2 has a separate electronic housing 27, wherein the electronic housing 27 is snap-fitted into the side wall 11 of the housing 9, 10. For this purpose, the electronic housing 27 has several locking elements 19 that engage in corresponding counter-structures of the housing part 9. The electronic housing 27 projects from the side wall 11 in the transverse direction Y and is flush with the housing 9, 10 in the vertical direction Z and in the longitudinal direction X.

[0060] The electronic housing 27 has several ventilation openings and recesses 29, the recesses 29 serving to make the display means 28, namely light-emitting diodes, which are connected to the circuit board 17, visible from the front 4 of the device.

[0061] The electronic component 2 further comprises a photoelectric sensor 25 connected to the circuit board 17, the photoelectric sensor 25 serving to detect the switching position of the slider 31. For this purpose, for example, a dimming structure (not shown in detail) can extend from the side wall 11 of the housing 9, 10, and this dimming structure is connected to the slider 31. Depending on the switching position of the slider 31, this dimming structure, or at least a section of it, is located either within or outside the area of ​​the photoelectric sensor 25, thereby enabling the photoelectric sensor to detect the switching position of the slider 31.

[0062] The circuit board 17 and the electronics housing 27 can be plugged onto the side wall 11 from the outside in the direction of arrow 30, thus in the transverse direction Y. It is quite conceivable that the circuit board 17 is first connected to the housing 9, 10 of the switching device 1 and then the electronics housing 27 is connected to the housing 9, 10 of the switching device 1.

[0063] The Figures 17 and 18 Figure 1 shows a third embodiment of the invention, which differs from the second embodiment essentially in the design and configuration of the circuit board 17. Specifically, the third embodiment does not include Hall sensors for current measurement. Accordingly, shielding plates are not required in the third embodiment. Essentially, the third embodiment serves for fuse monitoring, whereby the status of each fuse can be transmitted to external evaluation, monitoring, and / or control devices via the communication interface 26.
