Description

Technical Field

[0001] The invention relates to a remote driver for a low-voltage protective switchgear, such as a line protective switchgear or a residual current protective switchgear, having a controllable drive for operating the protective switchgear and a method for parameterizing such a remote driver. Background Art

[0002] Remote actuators enable remote operation of low-voltage protection switchgear. This type of low-voltage protection switchgear is also known as rail-mounted equipment. In this case, the remote actuator is mechanically coupled to the protective switching device and can be used both for remote disconnection and for remote connection of the protective switching device. Such a remote actuator is known in principle from the prior art, for example from German patent specification DE 102 16 055 B4.

[0003] For example, circuit breakers, line protection switches (LS switches), fault current protection switches (FI switches), fire protection switches, combined devices such as FI-LS protection switchgear or load disconnectors are considered as protection switchgear for coupling to remote drives.

[0004] Here, the circuit breaker is specially designed for high currents. A line protection switch (so-called LS switch) is an overcurrent protection device used in electrical equipment and is used in particular in the field of low-voltage power networks. Circuit breakers and line protection switches ensure safe shutdown in the event of a short circuit and protect electrical consumers and electrical equipment from overload, for example from damage to electrical lines due to overheating caused by excessive current. They are designed to automatically disconnect the current circuit to be monitored in the event of a short circuit or in the event of an overload, and thus separate it from the rest of the power grid. Therefore, circuit breakers and line protection switches are used in particular as switching elements and safety elements for monitoring and protecting electrical current circuits in power supply networks. In principle, line circuit breakers are known from the publications DE 10 2015 217 704 A1, EP 2 980 822 A1, DE 10 2015 213 375 A1, DE 10 2013 211 539 A1 or EP 2 685 482 B1.

[0005] With the aid of a residual current circuit breaker, personal protection, property protection or fire protection can also be achieved. A residual current circuit breaker is a switching device that, in the event of a fault in electrical devices and installations, switches off these electrical devices and installations in the shortest possible time and thus disconnects them from the remaining network if a current flows to the earth in a "wrong path", for example through a person's body. For this purpose, the residual current circuit breaker compares the current intensity of the current flowing to the consumer with the intensity of the current flowing back from the consumer. Residual current circuit breakers are known, for example, from the documents EP 0 957 558 A2, DE 10 2014 208 036 A1 or DE 10 2014 202 485 A1.

[0006] Furthermore, the prior art also knows switchgear that does not have its own protection function. This includes, for example, so-called load switches, disconnectors or load disconnectors. The latter is understood to be a switchgear that, in terms of its functionality, meets both the requirements for load switches (switching under electrical load) and the requirements for disconnectors (separating electrical device components in a nearly power-free manner). In low-voltage power grids, disconnectors are used, for example, to interrupt the main current circuit in the main distribution area.

[0007] However, the installation of remote drives is relatively complex, since information about the circuit breakers to be coupled to the remote drive must first be provided on the remote drive. By way of example, the torque required for operating the coupled circuit breaker device may be mentioned, which depends in particular on the number of switch points to be switched. Furthermore, maintenance of the circuit breaker device or the remote drive is usually carried out preventively, since there is no information about the current state of the device. Summary of the invention

[0008] The object of the present invention is therefore to provide a remote driver for a low-voltage protection switchgear and a method for parameterizing a remote driver, which are characterized by low installation and maintenance costs.

[0009] According to the invention, this technical problem is solved by a remote driver according to the invention for coupling to a low-voltage protection switchgear and a method for parameterizing a remote driver, which is configured to be coupled to a low-voltage protection switchgear. Advantageous embodiments of the remote driver according to the invention and of the method according to the invention are the subject matter of the invention.

[0010] The remote driver according to the present invention is used to couple with a low-voltage protection switch device so as to operate it with the help of a controllable drive device of the remote driver, that is, to switch the coupled protection switch device on or off, and has a processing device, which itself has a storage device for storing reference data of different protection switch devices that can be coupled, a first interface by means of which actual data related to the protection switch device to be coupled or coupled can be collected, and a comparator device for comparing the actual data with the reference data of the protection switch device involved.

[0011] By means of the processing device, actual data of the protective switchgear to be coupled to the remote drive or coupled to the remote drive can be collected via the first interface and compared with existing reference data. In this way, the remote drive can be automatically set up as required during installation, for example, with respect to settings for the switch-on speed or the switch-on torque. This significantly reduces the installation costs.

[0012] In an advantageous development of the remote driver, the actual data of the protective switching device contain information about the device type.

[0013] Advantageously, the actual data contain information about the device type of the protective switching device to be coupled or coupled. By comparison with reference data of possible protective switching devices, i.e., devices that can in principle be coupled to the remote driver, it is possible to automatically determine which type and kind of protective switching device should be coupled or has been coupled to the remote driver. This can significantly simplify the parameterization of the remote driver.

[0014] In a further advantageous embodiment of the remote drive, the information about the device type is recorded manually or automatically via the first interface.

[0015] This information can be collected manually or automatically via the first interface. For example, within the scope of electrical installation, a technician can collect actual data by reading a barcode or QR code applied to the protective switchgear with the help of a smartphone app and transmit this actual data to a remote driver via the first interface. Alternatively, it is possible that the protective switchgear to be coupled has its own communication device and can therefore communicate directly with the remote driver. This further simplifies the installation work.

[0016] In a further advantageous embodiment of the remote drive, the actual data contain current wear information of the coupled protective switching device.

[0017] By measuring the torque values ​​or acceleration values ​​required for switching on or off and comparing them with reference values ​​assigned to the relevant protective switching device type, the mechanical losses of the connected protective switching device can be inferred. By means of a comparator device, the measured loss values ​​are compared continuously (i.e., in each switching process) or at discrete intervals with reference values ​​stored in the reference data in order to obtain current information about the loss state of the connected protective switching device.

[0018] Before reaching the corresponding predefined wear limit value (which is also contained in the reference data), a message about the impending end of the service life of the connected circuit breaker can be issued, thereby preventively starting the replacement of the circuit breaker. Replacements that are triggered only by the passage of time but are not yet required due to wear are effectively prevented.

[0019] After the loss limit value is exceeded, the protective switch device can be automatically switched off via the connected remote drive, wherein a re-closing can also be prevented. In this way, dangerous operating states such as impermissibly high heating or undefined switch positions due to excessive torques when switching on or off can be avoided. This significantly increases the operating safety of the device.

[0020] In a further advantageous embodiment of the remote drive, the processing device has at least one measuring line for detecting current wear information.

[0021] By means of the measuring line, for example, the voltage drop across one phase (or all phases) of the coupled protective switchgear can be detected, from which the contact loss on the switch contact assigned to the corresponding phase can be inferred. In the case of multi-pole switchgear, the voltage drop is advantageously detected across all phases by means of the measuring line. Suitable measuring circuits are advantageously integrated into the processing device of the remote drive. This makes it possible to effectively prevent dangerous operating states. In addition, maintenance or replacement of the switchgear can be controlled as required.

[0022] In a further advantageous embodiment, the remote drive has a torque sensor in order to detect a torque occurring when a coupled protective switching device is switched on and / or off and to compare this torque with a permissible reference value.

[0023] The measurement of the acceleration or angular velocity can be realized, for example, by means of a Hall sensor arranged in the remote drive, which detects the speed / acceleration of the drive component of the drive device equipped with a magnet. If corresponding values ​​are stored in the reference data, these corresponding values ​​can be compared with the measured actual values ​​continuously (i.e. in each switching process) or in discrete intervals by means of a comparator device.

[0024] Before reaching the corresponding predefined torque limit value (which is also contained in the reference data), a message about the impending end of the service life of the connected protective switching device can be issued. After exceeding the torque limit value, the protective switching device can be automatically switched off via the connected remote drive and prevented from being switched on again in order to avoid dangerous operating states. This significantly simplifies maintenance and at the same time significantly increases the operating safety of the device.

[0025] In a further advantageous embodiment of the remote drive, the first interface is designed to be wireless.

[0026] In an advantageous manner, known transmission standards such as ZigBee, Bluetooth or IR are used for the wireless data exchange via the first interface. However, the invention is not limited to the standards mentioned.

[0027] In a further advantageous embodiment, the remote driver has a second interface in order to exchange data with a superordinated unit.

[0028] Advantageously, the second interface for exchanging information with a superordinate unit is designed to be bidirectional. For example, critical operating states can be transmitted from the remote driver to a superordinate organization, such as a control room. On the other hand, data (e.g. reference data of the coupled protective switchgear) can be transmitted from the superordinate organization to the remote driver, so that it is not necessary to store data about all protective switchgear that can be coupled to the remote driver in the storage device of the remote driver. This significantly reduces the storage requirements. In addition, a storage device that can be designed to be smaller in size has a favorable effect on the manufacturing costs and the space requirements. In this case, the second interface can be designed both wirelessly and wired.

[0029] The method according to the invention for parameterizing a remote driver of the type described above, which is provided for coupling to a low-voltage protection switchgear, comprises the following steps:

[0030] a) Collecting actual data of the protective switchgear to be coupled to the remote drive or coupled to the remote drive,

[0031] b) transmitting the collected actual data to a processing device of the remote drive,

[0032] c) comparing the acquired actual data with reference data of a possible protective switchgear device stored in a storage device, and

[0033] d) Identify the protective switchgear to be coupled or coupled.

[0034] By means of the parameterization method according to the invention, the parameterization of a protection switch device equipped with a remote driver can be significantly simplified. In this case, the acquisition of the actual data of the protection switch device can be done both manually by a technician, for example, by means of a suitable application (App) on a smartphone or similar device, or automatically (if the protection switch device is a protection switch device with communication capabilities).

[0035] In an advantageous embodiment, the method has the additional step of:

[0036] e) If the acquired actual data deviate from the stored reference data in a predefined manner, the coupled protective switching device is switched off.

[0037] In this way, critical operating states can be detected and switched off in a preventive manner, thereby further increasing the operating safety of the electrical device.

[0038] In a further advantageous embodiment, the method comprises the further steps:

[0039] f) Outputting information to a superordinated unit by means of the second interface, wherein the information contains the reason for shutting down the coupled protective switching device.

[0040] This makes it possible, for example, to preventively start replacing a protective switchgear that will soon enter a critical operating state. This minimizes downtime and further improves the availability of the electrical installation. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] Figure 1 A schematic diagram of a remote actuator 1 is shown in a perspective view. The remote actuator 1 has an insulating material housing 2, which has a front side 4, a fastening side 5 opposite the front side 4, and a narrow side 6 and a wide side 7 connected to the front side 4 and the fastening side 5. An operating element 3 is arranged on the front side 4, which can be connected to an operating element of a protective switch device 100 (see Figure 2 ) so that the protective switch device 100 (in the coupled state) can be operated by means of the remote driver 1. Via the fixing side 5, the remote driver 1 can be fixed to a support rail or a top-hat rail (not shown), which is mainly used for fixing devices in electrical installation distributors. For connection with the protective switch device 100, the remote driver 1 also has two connecting pieces 9, which are arranged on the front side 4 in the area of ​​the wide side 7 and can be inserted into a receptacle 109 formed on the housing 102 of the protective switch device 100, so as to mechanically connect the remote driver 1 to the protective switch device 100.

[0049] Figure 2 In the figure, a remote drive 1 coupled to a three-pole protection switch device 100 is schematically shown in a stereoscopic view. At present, the protection switch device 100 is designed as a three-pole. However, this is not necessary for the present invention and should therefore only be understood as an example. According to the present invention, the remote drive 1 can be coupled to a single-pole protection switch device and to different multi-pole (i.e., two-pole, three-pole or four-pole) protection switch devices 100. Only the handle connector 8 to be used must be matched to the width of the protection switch device 100 to be coupled, and if necessary, to the type of the protection switch device 100 to be coupled.

[0050] In order to couple the remote actuator 1 to the protection switch device 100, the two devices are arranged so that their broad sides 7 face each other. In order to mechanically fix the two devices, the two connecting pieces 9 of the remote actuator are now inserted into the receptacles 109, which are arranged accordingly in terms of their position on the front side of the protection switch device 100. In addition, the functional coupling of the operating element 3 of the remote actuator 1 and the operating element 103 of the protection switch device 100, which is achieved by means of the common handle connector 8, serves as an additional mechanical coupling, thereby achieving a stable mechanical connection of the two devices.

[0051] Figure 3, the conceptual structure of a remote drive 1 according to the invention is now schematically shown in a side view. The remote drive 1 has a drive device 20 for remotely operating an operating element 3. For this purpose, the operating element 3 is arranged protrudingly on the handle roller 11, so that when the operating element 3 is operated, the handle roller 11 rotates about its rotation axis 12. In the example shown, the drive device 20 has, in addition to an electric motor (not shown), a transmission with a gear 21, which meshes with a toothed section 13 constructed on the circumference of the handle roller 11. With the help of this motor-transmission unit, the rotational speed of the electric motor can be matched to the torque required for operating the protective switch device 100 coupled to the remote drive 1 and therefore to the mechanical load coupled to the operating element 3 via the handle connector 8. However, for the sake of clarity, the motor and the transmission are not shown in the figure. Figure 3 , or not shown completely. Furthermore, the drive device 20 can also be designed without gears: in this case, the electric motor can be controlled in a speed-controlled manner and directly (i.e. without transmission via one or more transmission stages) acts on the toothing 13 formed on the handle roller 11. The energy required for the drive device 20 is provided by an energy storage device 22. For this purpose, for example, a capacitor or a battery is used, which, as a buffer memory, stores and, when necessary, provides the amount of energy required for operating the operating element 3 connected to the mechanical load.

[0052] In order to control the drive device 20, the remote driver 1 has a printed circuit board 10, which has a data processing device 30, such as a processor or a microcontroller. In addition, the processing device 30 is equipped with a storage device 31, which is used to store reference data of different protective switchgears that can be coupled. Via a first interface 33 of the processing device 30, actual data of the protective switchgear 100 that has been coupled or is to be coupled to the remote driver 1 can be collected. In addition, the processing device 30 has a comparator device 32, which is used to compare the collected actual data with the stored reference data of the corresponding protective switchgear 100. The second interface 35 of the processing device 30 is used to exchange data with a superordinate unit, such as a control center.

[0053] The memory device 31 and the comparator device 32 can be arranged as independent functional blocks on the circuit board 10, and can be electrically connected to the processor or microcontroller via the circuit board. However, the memory device 31 and / or the comparator device can also be a component of a larger integrated circuit, which also includes the processor or microcontroller of the processing device 30 if necessary.

[0054] Advantageously, the first interface 33 and the second interface 35 are designed to be wireless. For example, ZigBee, Bluetooth or infrared can be used as a transmission standard; however, this is not necessary for the invention. The wireless interface can be arranged directly on the circuit board 10; in the case of a wired interface, on the other hand, a suitable connection possibility should be provided in the area of ​​the housing surface. It is also possible that the first interface 33 and the second interface 35, in particular if they are designed to be wireless, can use common transmission hardware and receiver hardware.

[0055] Figure 4 The remote drive 1 with coupling is schematically shown in FIG. Figure 2 The equivalent circuit diagram of the protective switch device 100 shown in FIG. Three electrical connecting lines L1, L2 and L3 are connected to the three-pole protective switch device 100 on the input side and the output side, and the three electrical connecting lines are respectively assigned to an electrical load circuit, which has a respectively assigned electrical load F1, F2 or F3. Inside the protective switch device 100, the input terminals and output terminals of the three connecting lines L1, L2 and L3 are respectively connected in an electrically conductive manner via a current path guided in the protective switch device 100. Via the switch contacts S1, S2 and S3 directly and uniquely assigned to the corresponding current path, the current path can be interrupted by opening the switch contacts S1, S2 and S3 when necessary (i.e., when a corresponding situation occurs, such as a short circuit).

[0056] In order to operate the three switching contacts S1, S2 and S3, the protective switchgear 100 has a switching mechanism (not shown in more detail), which is connected to the drive device 20 of the remote drive 1 via a mechanically effective connection 104. In this way, the three switching contacts S1, S2 and S3 can be opened via the remote drive 1 to interrupt the current path assigned to the three switching contacts S1, S2 and S3 and thus separate the load circuits L1, L2 and L3 from the electrical conductor network. Likewise, the three switching contacts S1, S2 and S3 can be closed again by means of the remote drive 1 to restore the power supply to the load circuits L1, L2 and L3.

[0057] In order to determine suitable loss information with respect to the increased contact loss of the switching contacts S1, S2 and S3, the processing device 30 has a plurality of measuring lines 34, which are each clearly assigned to one of the switching contacts S1, S2, S3. The measuring lines 34 are used to determine the voltage drop across the respective switching contacts S1, S2, S3, from which any contact loss present at the respective switching contacts S1, S2, S3 can be inferred.

[0058] According to the following Figure 5The method according to the invention for parameterizing a remote driver 1 which is provided for coupling to a low-voltage protection switchgear device 100 and is designed according to the type described above is briefly explained:

[0059] In a first method step 201, actual data of the protective switch device 100 to be coupled to the remote drive 1 or coupled to the remote drive 1 are collected. If the protective switch device 100 itself already has communication capabilities, the protective switch device can independently transmit its actual data to the remote drive 1. In this case, the actual data is used to identify the device type of the protective switch device 100 to be coupled or coupled. However, if the protective switch device 100 itself does not have communication capabilities, the actual data can also be collected "manually", that is, manually via the first (preferably wireless) interface 33, for example with the help of a suitable application for a smartphone, tablet or other mobile device.

[0060] In a second method step 202 , the actual data of the protective switching device 100 are transmitted to the processing device 30 of the remote driver 1 .

[0061] In a third method step 203 , the transmitted actual data are compared with possible reference data, ie suitable for the coupled protection switching device, which are stored in the memory device 31 , by means of the comparator device 32 .

[0062] In a fourth method step 204 , the protective switching device 100 to be coupled or coupled is identified if the acquired actual data agree with the stored reference data.

[0063] Once the device type of the connected protection switch device 100 is identified, the corresponding operating data of the connected protection switch device 100 can be uploaded via the second interface 33 of the processing device 30 of the remote driver 1, and corresponding settings can be made. Relevant operating data are, for example, switching speed, maximum torque, voltage drop data, required force / torque window, maximum number of switching cycles, etc. Based on these data, by comparing with the current actual data of the protection switch device 100, it can be identified when the service life of the coupled protection switch device 100 ends.

[0064] For example, an inadmissibly high melting loss on the switch contacts of the protective switch device 100 can be detected by a higher voltage drop on the relevant switch contacts, which is caused, for example, by switching on and off short-circuit currents or by a high number of switching cycles under high electrical loads. For this purpose, each switch contact of the coupled protective switch device needs to be monitored accordingly. This can be achieved, for example, by a suitable measuring circuit for each switch contact, which is connected to the processing device 30 arranged in the remote drive 1. In this case, the voltage drop of each switch contact can be designed in multiple stages:

[0065] -Normal voltage drop: normal operation, no measures;

[0066] - increased voltage drop: a corresponding warning is output via the remote driver 1, but no further action is taken;

[0067] - Voltage drop above a predefined limit value: The end of the service life of the connected protection switch device 100 is determined by means of a corresponding message from the remote driver 1 to the upper-level unit, and the protection switch device 100 is automatically switched off by the remote driver 1, wherein reconnection of the protection switch device 100 by the remote driver 1 is effectively avoided until the protection switch device 100 is repaired or replaced.

[0068] Furthermore, an increased torque during switching on or off may also indicate the end of the mechanical service life of the connected protection switchgear 100 due to wear or contamination of the switching mechanism of the protection switchgear 100. The torque required for operating the operating element of the protection switchgear 100 can be determined with the aid of a torque sensor arranged on the operating element 3 of the remote drive 1. For this purpose, for example, the acceleration or angular velocity of the operating element 3 of the remote drive 1 is measured with the aid of a Hall sensor. Here again, the reaction of the remote drive 1 can be designed in multiple stages:

[0069] -Measurement values ​​within normal range: normal operation, no measures;

[0070] - Increased measured value: A corresponding warning is output via the remote driver 1, but no further measures are taken;

[0071] - Measured values ​​above predefined limit values: The end of the service life of the connected protection switch device 100 is determined by means of a corresponding message from the remote driver 1 to the upper-level unit, and the protection switch device 100 is automatically switched off by the remote driver 1, wherein reconnection of the protection switch device 100 by the remote driver 1 is effectively avoided until the protection switch device 100 is repaired or replaced.

[0072] Therefore, the parameterization method according to the invention can be supplemented by further method steps:

[0073] In a fifth method step 205, if the acquired actual data deviate from the stored reference data in a predefined manner, a shutdown of the coupled protective switching device 100 can be initiated. In this way, dangerous operating states, such as impermissible heating due to excessively burned contacts or undefined switch positions due to excessive torques when switching on or off, can be effectively avoided.

[0074] Furthermore, the fifth method step 205 can be supplemented by outputting information to a superordinated unit in a sixth method step 206 by means of the second interface 35, which information contains the reason for shutting down the coupled circuit breaker device 100. In this way, maintenance / repair of the electrical installation is significantly simplified.

[0075] Working data reflecting the characteristics of each device type of the coupled protective switch device 100 can be uploaded to the storage device 31 of the remote driver 1 within the range of the given parameters with the help of a parameter setting device (such as a smart phone) or via a second interface 35, and the connection between the remote driver 1 and a superior organization, such as a control room, is realized via this second interface.

[0076] With the remote actuator 1 according to the invention, the actual or impending end of service life of a protection switchgear 100 coupled to the remote actuator can be detected. This applies both to the end of the electrical service life due to increased contact loss at one or more switching contacts of the protection switchgear 100 and to the end of the mechanical service life due to contamination or wear of the switching mechanism of the protection switchgear 100.

[0077] In the event of an imminent end of service life, a message can be issued to prompt timely replacement of the protective switchgear 100 before it eventually fails. It is no longer necessary to prematurely replace a still functional protective switchgear 100, for example due to fixed maintenance cycles governed by the passage of time.

[0078] At the end of the actual service life, the protection switch device 100 is shut down by the remote drive 1 to prevent it from being switched on again until the device is replaced. In this way, dangerous operating states such as impermissible heating due to excessively burned contacts or undefined switch positions due to excessive torques when switching on or off can be effectively avoided.
