Description

FIELD OF INVENTION

The present disclosure relates to industrial automation. In particular, the present disclosure relates to a multi-use control system for a switchgear module, a switchgear module comprising a multi-use control system and a method for operating a switchgear module by means of a multi-use control system.

BACKGROUND

Switchgear technology is widely implemented in electrical power systems, such as industrial automation and robotic systems, in order to provide effective control and reliable protection for the embedded electrical components. In particular for low-voltage applications, switchgear modules may regulate power distribution within the electrical power systems, ensuring efficient operation and optimal management of electrical loads. Equipped with protective components such as circuit breakers and fuses, such switchgear modules may safeguard against overcurrent and short circuits, minimizing the risk of equipment damage or accidents. Further, these modules may offer flexibility in installation, expansion, and maintenance, for example for the the automation and robotic systems. It may thus be of great importance that these switchgear modules may be implemented and operated in a well-controlled manner.

SUMMARY

It may be seen as an objective of the invention to provide an improved control system for seamless operating a switchgear device with an optimized flexibility and reliability.
The objective is achieved by the subject matter of the independent claims. The dependent claims, the following description and the drawings show embodiments of the invention.
According to a first aspect of the present disclosure, a multi-use control system is provided for a switchgear module. The multi-use control system comprises a first rotating element that comprises a sliding element, a second rotating element, which comprises an elongated opening and is connectable to the switchgear module that is switchable between a plurality of modes of operation, and an interlocking element that is configured to secure the switchgear module to or release the switchgear module from a compartment. The first rotating element is connectable to an operating element that is rotatable between a plurality of angular positions comprising a first group of angular positions and a second group of angular positions.
The sliding element is configured to interconnect with and slide along the elongated opening, and to transmit a rotational motion from the first rotating element to the second rotating element for switching the switchgear module between the plurality of modes of operation, when the operating element rotates between the first group of angular positions.
Further, the sliding element is configured to disconnect from the elongated opening and to allow the first rotating element transmitting the rotational motion to the interlocking element for securing or releasing the switchgear module, when the operating element rotates between the second group of angular positions.
When the operating element may pivot between the first group of angular positions for switching the modes of operation of the switchgear module, the first rotating element and the second rotating element may be coupled and interconnected with each other in a so-called internal Geneva-like drive mechanism by means of the interacting sliding element of the first rotating element and the elongated opening arranged at the second rotation element. As such, the first rotating element, the second rotating element and the operating element may form a switching assembly, which may perform a switching mechanism for the switchgear module, since the second rotating element may further be connected to a main switch of the switchgear module.
In contrast, when the operating element may pivot between the second group of angular positions for securing or releasing the switchgear module, the first rotating element may come into contact or collide with the interlocking element and drive the interlocking element to move and/or rotate, for example to unlock the secured switchgear module inside the compartment. Hence, the first rotating element, the interlocking element and the operating element may form together an interlocking assembly, which may perform an interlocking mechanism for the switchgear module.
In other words, the Geneva-like drive mechanism for the first and second rotating elements via the sliding element and the elongated opening may transmit the angular position of the operating element to the main switch inside the switchgear module. Beyond the turning angle, the transmission may be interrupted. By turning the operating element as the main handle of the control system further, the interlocking mechanism may be released and the switchgear module may be brought into a releasing or moving position. If the operating element may get turned in the opposite direction, the interlocking mechanism may first lock the switchgear module in the compartment and then start to transmit the rotational motion of the operating element to the main switch being or connected to the second rotating element.
The control system may be designed to allow separate controlling over the switching assembly for the switching mechanism of the switchgear module or over the interlocking assembly for the interlocking mechanism of the switchgear module by means of the internal Geneva-like drive mechanism between the first and second rotating elements and the additionally arranged interlocking system. Further the control system may be designed to allow a seamless transition between the switching mechanism and the interlocking mechanism.
For example, the compartment may be a housing, in which the switchgear module may be placed or mounted, so that the switchgear module may be operated under a safety condition. The switchgear module may be released or detached from the compartment while not being operated. Hence, the switchgear module may be designed as a withdrawable switchgear module. In particular, the withdrawable switchgear module may be a low-voltage switchgear module.
According to an embodiment, the first rotating element may be designed to be a rotating lever arm that comprises a proximal end and a distal end.
The rotating lever arm may be designed to be elongated rod-shaped extending between the proximal end and the distal end. As the rotating lever, the first rotating element may exercise a force to drive the connected second rotating element to rotate and thus transmit the rotational motion, when the operating element may rotate between the first group of angular positions for switching the modes of operation of the switchgear module.
According to another embodiment, the sliding element may be arranged at the distal end of the first rotating element.
Alternatively or additionally, the sliding element may be arranged between the proximal end and the distal end of the first rotating element or the rotating lever arm. Preferably, the sliding element may be arranged closer to the distal end than the proximal end to ease the transition of the rotational motion of the rotating lever arm to the second rotating element via the sliding element being guided along the through opening of the second rotating element.
According to another embodiment, the multi-use control system may further comprise the operating element, which may be a handle that is configured to connect to the first rotating element at the proximal end via a shaft.
The operating element may be configured to control the switching assembly to switch the switchgear module between the plurality of modes of operation, when pivoting between the first group of angular positions, and to control the interlocking assembly to secure or release the switchgear module, when pivoting between the second group of angular positions.
The operating element may be arranged on the front of the switchgear module. Further, the operating element and the shaft may be connected to the first rotating element at the proximal end of the first rotating element, so that the driving force may be transmitted from the handle to the first rotating element.
According to another embodiment, the first rotating element may be configured to rotate about a first rotational axis passing through the proximal end of the first rotating element, when the operating element may rotate between the plurality of angular positions.
The first rotational axis of the first rotating element may be vertical to the elongated rotating lever arm. The proximal end of the first rotating element may thus be a first rotating point. Since the operating element may be connected to the first rotating element via the shaft at the proximal end, the operating element and the connecting shaft may also be configured to rotate about the same first rotational axis.
According to another embodiment, the sliding element may be a sliding pin, a sliding clamp or a sliding screw.
According to another embodiment, the elongated opening may comprise a first end and a second end. The sliding element of the first rotating element may be configured to be guided to slide between the first end and second end of the elongated opening, and to drive the second rotating element to rotate about a second rotational axis, when the operating element may rotate between the first group of angular positions.
The elongated opening may be designed as a slot or a rail for the sliding element and configured to guide the sliding element to move or slide along the rail, after the sliding element may be coupled or connected to to the elongated opening.
According to another embodiment, the second rotational axis of the second rotating element may be arranged in parallel to the first rotational axis of the first rotating element.
The second rotating element may also comprise an elongated shape extending from a second rotating point of the second rotating element may be arranged, to the second end of the elongated opening of the second rotating element.
According to another embodiment, the first end of the second rotating element may be a closed end and the second end of the elongated opening may be an open end. The sliding element may be configured to slide off the elongated opening at the open end, when the operating element may rotate between the second group of angular positions.
For example, when the operating element may drive the first rotation element to rotate or pivot in a direction, preferably in a clockwise direction for a transition from the switching mechanism towards the interlocking mechanism, the sliding element may be configured to slide from the first, closed end of the elongated opening to the second, open end of the elongated opening, at which the sliding element may further slide off the elongated opening. The sliding of the sliding element may be configured to convert the rotational motion of the first rotating element into the rotational motion of the second rotation element about the second rotating axis passing through the second rotation point of the second rotation element. The second rotation point may be arranged at the opposite end of the elongated second rotating element to the second, open end of the elongated opening. Alternatively, the second rotation point may be arranged between the opposite end of the second rotating element and the second, open end of elongated opening.
Driven by the transmitted rotational force or motion, the second rotating element may rotate in a corresponding direction or a clockwise direction.
According to another embodiment, the plurality of modes of operation of the switchgear module may comprise a first mode of operation, a second mode of operation and/or a third mode of operation. The first group of angular positions of the operating element may comprise a first angular position, which may be configured to interconnect with the first mode of operation of the switchgear module, and a second angular position, which may be configured to interconnect with the second mode of operation of the switchgear module, and/or a third angular position, which may be configured to interconnect with the third mode of operation of the switchgear module.
According to another embodiment, the first mode of operation of the switchgear module may be an ON-mode, the second mode of operation of the switchgear module may be an OFF-mode, and/or the third mode of operation of the switchgear module may be an TEST-mode.
The first angular position of the operating element may be a 0° angular positon, the second angular position of the operating element may be a 90° angular positon or a 135° angular position and/or the third angular position of the operating element may be a 135° angular positon.
In the ON-mode, the switchgear module may be inserted or secured in the compartment, a main switch of the switchgear module may be closed, the main circuit and control circuit of the switchgear module may be connected. In the OFF-mode, the switchgear module may be inserted or secured in the compartment, the main switch of the switchgear module may be open, the main circuit and the control circuit of the switchgear module may be disconnected. A padlocking for the switchgear module may be provided for the OFF-mode. In the TEST-mode, the switchgear module may be inserted or secured in the compartment, the main switch of the switchgear module may be open, the main circuit of the switchgear module may be disconnected. A padlocking for the switchgear module may be provided for the TEST-mode. Compared to the OFF-mode, the additional TEST-mode may be designed to allow the control circuit being still connected.
According to another embodiment, the second group of angular positions of the operating element may comprise a closed angular position, which may be a 90° angular position or a 135° angular position, and an open angular position, which may be a 180° angular position.
According to another embodiment, the sliding element may be configured to collide with the interlocking element and to transmit the rotational motion of the first rotating element to a translational motion of the interlocking element for releasing the switchgear module, when the operating element may rotate to the open angular positions.
For example, the interlocking element may be a rocker switch for securing the switchgear module inside the compartment. The interlocking element may comprise an interlocking pin being arranged at an end of the interlocking element adjacent to the first rotation element. After the sliding element may slide off the elongated opening, the control system may be configured to allow a collision between the sliding element and the interlocking pin at the 180° angular position for a RELEASE-mode, in which the switchgear module may be released or withdrawable from the compartment.
The closed angular position may correspond to an initial position for the switchgear module being locked or secured inside the compartment. When the operating element may rotate between the closed and open angular positions, the first rotation element may rotate freely for a while without interacting with both the second rotating element and the interlocking element until reaching the closed or open angular position.
By rotating the operating element in an opposite direction to reverse the rotation direction of the first pivoting element, for example in a counterclockwise direction, the first rotating element may disconnect from the interlocking system to allow the interlocking pin moving and/or rotating back to the initial position as the closed, locking position, so that the switchgear module may be secured in the compartment again.
The 90° or 135° angular position may be a turning angular point, by which a transition between the switching mechanism and the interlocking mechanism may take place by rotating the operating element across the turning angular point.
The multi-use control system comprising the various components comprising the first and second rotating elements following a Geneva-like drive mechanism and the interlocking element may allow the separation and the transition of the switching and interlocking mechanisms for the switchgear module in a continuous manner using the single operating handle. In other words, the transition from the controlling over the switching assembly to the controlling over the interlocking assembly in the continuous direction may be performed as a result of the sliding of the sliding element of the first rotating element off the elongated opening of the second rotating element and the collision of the first rotating element with the interlocking element.
Further, the single operating element or handle may be arranged on the front of the switchgear module and fulfill two separate functions safely and reliably: the switching of the switching device or the main switching device into all its possible positions, such as the ON-, OFF-, TEST-positions, which may be set by various angular positions covering a first angular rage of 0°, 90° and/or 135° angular positions, and the locking or releasing the entire switchgear module inside its compartment by transmitting the rotary motion of the main handle to the interlocking element via the first rotating element, when rotating covering the second angular range or the second groups of angular positions. This mechanism may ensure that the main switching assembly may be switched to the OFF-mode and/or the TEST-mode, before the switchgear module may be released. Once the switchgear module may be secured to into the compartment again, the mechanism may ensure that the switching assembly may first be switched to the TEST-mode and/or OFF-mode and then to the operating ON-mode. In particular, in order to meet the first functional requirement, the rotary motion of the operating handle on the switchgear module front may be translated to the main switching assembly via the first and second rotating elements interconnecting each other in the Geneva-like drive mechanism, so that the turning angles of the handle and the sense of the rotation of the switching assembly for the respective modes of operation may correspond to each other.
Alternatively, for example, the first angular position, the second angular position and/or the third angular position may be any angular position between 0° and 180° arranged in a sequence along the same direction for pivoting the operating element and the respective first and second pivoting elements being coupled with each other. As such, the predefined turning angular position being the second or third angular position may be arranged between 0° and 180°. Further, after the transition from the switching mechanism to the interlocking mechanism for the switchgear module, the pivoting element may drive the first pivoting element to the open angular position for releasing the switchgear module, which may be arranged, alternatively to the 180° angular position, between the turning angular position and the 180° angular position, or at a larger angular position between 180° to 360° angular positions, preferably between 180° to 270° angular positions, preferably between 180° or 225° angular positions.
According to a second aspect, a switchgear module is provided, which comprises a multi-use control system. The switchgear module is a low-voltage switchgear module.
The switchgear module may be a low-voltage switchgear module, which may be configured to operate at a voltage range between 0 V and 1000 V. Alternatively, the switchgear module may be a medium-voltage or high-voltage switchgear module. And the multi-use control system may be integrated in the medium-voltage or high-voltage switchgear module.
Further, a use of a multi-use control system for a switchgear module may be provided for a safe operation of the switchgear module in an electrical power system, for example in an automatic system or a robotic system.
With the first and second rotating elements, respectively, being designed to be two flat parts that only need to be combined or connected with cost efficient parts such as screws and/or pins, the manufacturing costs for the compact control system 100 for the switchgear module may be significantly reduced.
According to a third aspect, a method for operating a switchgear module by means of a multi-use control system is provided. The method comprises the following steps: connecting a first rotating element to an operating element that is rotatable between a plurality of angular positions comprising a first group of angular positions and a second group of angular positions; interconnecting the sliding element with the elongated opening, guiding the sliding element to slide along the elongated opening, and transmitting a rotational motion from the first rotating element to the second rotating element for switching the switchgear module between the plurality of modes of operation, while rotating the operating element between the first group of angular positions; disconnecting the sliding element from the elongated opening and allowing the first rotating element transmitting the rotational motion to the interlocking element for securing or releasing the switchgear module, while pivoting the operating element between the second group of angular positions.
Additionally, the method may further comprise the step of rotating the operating element in an opposite direction for securing the switchgear module to the compartment by disconnecting the first rotating element from the interlocking element, interconnecting the sliding element with the elongated opening transiting the controlling over the interlocking assembly to the controlling over the switching assembly and guiding the sliding element to slide along the elongated opening, and rotating the operating element between the first group of angular positions for switching the switchgear module between the plurality of modes of operation.

A download product is an instance of the computer program that may be sold and downloaded online for immediate fulfilment in lieu of physically shipping a machine-readable data carrier.
There may be provided one or more computers and/or compute instances with the computer program comprising machine-readable instructions that, when executed by one or more computers and/or compute instances, cause the one or more computers and/or compute instances to perform a method for operating a switchgear module by means of a multi-use control system in an electrical power system including an automation system and a robotic system, and/or with the machine-readable data carrier and/or download product with the computer program.
The method may be at least partly computer-implemented, and may be implemented in software or in hardware, or in software and hardware. Further, the method may be carried out by computer program instructions running on means that provide data processing functions. The data processing means may be a suitable computing means, such as an electronic control module etc., which may also be a distributed computer system.

DETAILED DESCRIPTION OF EMBODIMENTS

Fig. 1 and Fig. 2 show schematically an example of a multi-use control system 100 for a switchgear module 10, which may be a low-voltage switchgear module, respectively, in a perspective view and in a simplified side view. The multi-use control system 100 comprises a first rotating element 110, a second rotating element 120 and an interlocking element 220 and an operating element 160 which is also shown in Fig. 3.
The first rotating element 110 comprises a sliding element 115, which may be a sliding pin as shown in Fig. 1 and Fig. 2. Further, the first rotating element 110 may be designed to be a rotating lever arm comprising a proximal end 111 and a distal end 112. The sliding element 115 is arranged at the distal end 112 of the first rotating element 110. The first rotating element 110 is connectable to the operating element 160 which may be designed as a handle and is rotatable between a plurality of angular positions comprising a first group of angular positions 161, 162, 163 and a second group of angular positions 163, 164, as schematically shown in Fig. 3. In Fig. 1 and Fig. 2, the first rotating element 110 is connected with the operating element 160 and the shaft 150 at the proximal end 111. The first rotating element 110 may be configured to rotate about a first rotational axis passing through the proximal end 111 of the first rotating element 110, along with the shaft 150 and the operating element 160, when the operating element 160 may rotate between the plurality of angular positions.
The second rotating element 120 comprises an elongated opening 125 or a slot and may be connectable to the switchgear module 10 that is switchable between a plurality of modes of operation. Further, the elongated opening 125 comprises a first end 1251 and a second end 1252. While the first end 1251 of the second rotating element 120 may be a closed end, which may also be arranged at a second distal end of the second rotating element 120, the second end 1252 of the elongated opening 125 may be an open end being arranged in the middle region of the elongated second rotating element 120.
The sliding element 115 of the first rotating element 110 may be configured to interconnect with and slide along the elongated opening 125 and to transmit a rotational motion from the first rotating element 110 to the second rotating element 120 for switching the switchgear module 10 between the plurality of modes of operation, when the operating element 160 may rotate between the first group of angular positions 161, 162, 163, as shown respectively in Fig. 1 (a) to (c) and Fig. 2 (a) to (c). In other words, the sliding element 115 may be configured to be guided to slide between the first end 1251 and the second end 1252 of the elongated opening 125 and to drive the second rotating element 120 to rotate about a second rotational axis, when the operating element 160 may rotate between the first group of angular positions 161, 162, 163.
The second rotating element 120 may further comprise a second rotating point 128. The second rotational axis of the second rotating element 120 may be designed to pass through the second rotating point 128. The second rotational axis of the second rotating element 120 may be designed to be a parallel, but not identical, rotational axis to the first rational axis of the first rotating element 120.
The second rotating element 120 may further connect to the main switch of the switchgear module 10, so that the second rotating element 120 may rotate for switching the switchgear module 10 between the modes of operation. The plurality of modes of operation of the switchgear module 10 may comprise a first mode of operation, as shown in Fig. 1 (a) and Fig. 2(a), a second mode of operation, as shown in Fig. 1 (b) and Fig. 2(b), and a third mode of operation, as shown in Fig. 1 (c) and Fig. 2(c). The first mode of operation may be an ON-mode, in which the switchgear module may be switched to in a normal operation mode, while the second mode of operation may be an OFF-mode, in which the switchgear module 10 may be switched off or completely turned off. Also, in the ON-mode, the switchgear module 10 may be inserted or secured in the compartment, the main switch of the switchgear module 10 may be closed, the main circuit and control circuit of the switchgear module may be connected. In the OFF-mode, the switchgear module 10 may be inserted or secured in the compartment, the main switch of the switchgear module may be open, the main circuit and the control circuit of the switchgear module may be disconnected. In the TEST-mode, the switchgear module 10 may be inserted or secured in the compartment, the main switch of the switchgear module may be open, the main circuit of the switchgear module may be disconnected. Compared to the OFF-mode, the additional TEST-mode may be designed to allow the control circuit being still connected.
The first group of angular positions of the operating element 160 may comprise a first angular position 161 or a 0° angular position, which may be configured to interconnect with the first ON-mode of operation of the switchgear module 10 as shown in Fig. 1(a) and Fig. 2(a), a second angular position 162 or a 90° angular position, configured to interconnect with the second mode of operation of the switchgear module 10, as shown in Fig. 1(b) and Fig. 2(b), and a third angular position 163 or a 135° angular position, which may be configured to interconnect with the third TEST-mode of operation of the switchgear module 10 as shown in Fig. 1(c) and Fig. 2(c).
In order to disconnect the first and second rotating elements 110, 120 and interrupting the transmission of the rotational motion from the first rotating element 110 to the second rotating element 120, the sliding element 115 may be configured to slide off the elongated opening 125 at the open end 1252, when the operating element 160 may further rotate till the third 135° angular position 163 as a turning angular position, at the a transition between the switching mechanism and the interlocking mechanism of the switchgear module 10 may occur.
The interlocking element 200 may comprise an interlocking pin 215 and configured to secure the switchgear module 10 to or release the switchgear module 10 from a compartment for safely operating the switchgear module 10. The sliding element 115 may be configured to disconnect from the elongated opening 125 and to allow the first rotating element 110 transmitting the rotational motion to the interlocking element 200 for securing or releasing the switchgear module 10, when the operating element 160 rotates between the second group of angular positions 163, 164. The interlocking element 200 may be designed to be a rocker switch. The interlocking pin 215 may be provided at an freestanding end of the rocker switch adjacent to the first rotating element 110, so that the sliding element 115 may come into contact or collide with the interlocking pin 215 of the interlocking element 200 when rotating with the operating element 160 to an angular position of Fig. 1 (d) and Fig. 2 (d), at which the switchgear module 10 may be withdrawable from the compartment.
The second group of angular positions of the operating element 160 may comprise a closed angular position, which is a 135° angular position 163 as shown in Fig. 1 (c) and Fig. 2 (c), and an open angular position, which is a 180° angular position 164 as shown in Fig. 1 (d) and Fig. 2 (d) and may be configured to allow the switchgear module 10 being released from the compartment in a RELEASE-mode of the control system 100.
Fig. 3 further shows that the multi-use control system 100 having the operating element 160 may be arranged at the switchgear module 10. For example, the operating element 160 may be arranged at the outer surface of the switchgear module 10 or at the outer surface of the compartment for the switchgear module 10, so that the handle 160 may be pivotable from the exterior, and the other components such as the first and second rotating elements 110, 120 designed in the Geneva-like drive mechanism may be arranged inside the switchgear module 10 or inside the compartment for securing the switchgear module 10. The operating element 160 may pivot or rotate in two separate angular ranges including a first angular range 180, which may cover the 0°, 90° and 135° angular positions as the first group of angular positions 161, 162, 163, for switching the switchgear module 10 between the ON-, OFF- and/or TEST-modes and a second angular range 280, which may cover the 135° to 180° angular positions as the second group of angular positions 163, 164, for controlling the interlocking assembly to lock or release the switchgear module 10. Further, the operating element 160 may be designed to rotate continuously between the first angular range 180 and the second angular range 280, so that the switching mechanism and the interlocking mechanism for the switchgear module 10 may be transited seamlessly both in the counterclockwise and clockwise directions.
In Fig. 3, the second group of angular positions of the handle 160 may further comprise a closed angular position 163 and an open angular position 164. The closed angular position may be designed as a turning angular position, at which the switchgear module 10 may still be secured to the compartment as shown in Fig. 1 (c) and Fig. 2 (c), and the open angular position 164 may be configured to collide or interconnect with the interlocking element 200 at the interlocking pin 215 for releasing the switchgear module 10 from the compartment in a RELEASE-mode as shown in Fig. 1 (d) and Fig. 2 (d). The open angular position 164 may be set as a 180° angular position.
As shown in Fig. 1 (d) and Fig. 2 (d), the sliding element 115 of the first rotating element 110 may be configured to collide with the interlocking element 200, via the interlocking pin 215, and to transmit the rotational motion of the first rotating element 110 to a translational motion of the interlocking element 200 for releasing the switchgear module 10, when the operating element 160 may rotate to the open 180° angular position 164.
The Geneva-like drive mechanism for the first and second rotating elements 110, 120 via the sliding element 115 and the elongated opening 125 may transmit the angular position of the operating element 160 to the main switch inside the switchgear module 10. Beyond the turning angle 163, the transmission may be interrupted. By turning the operating element 160 as the main handle of the control system further, the interlocking mechanism may be released and the switchgear module 10 may be brought into a releasing or moving position. If the operating element 160 may get turned in the opposite direction, the interlocking mechanism may first lock the switchgear module 10 in the compartment and then start to transmit the rotational motion of the operating element to the main switch being or connected to the second rotating element 120.
In particular, as shown in Fig. 1 (a) to Fig. 1 (d), the operating element 160 may start to rotate from the first 0° angular position 161, at which the switchgear module 10 may be secured in the compartment and operate in the ON-mode. The sliding element 115 of the first rotating element 110 may be arranged at the first closed position 1251 of the elongated opening 125.
By rotating the operating element 160 for switching the switchgear module 10 to the OFF-mode at the second 90° angular position 162, as shown in Fig. 1 (b) and Fig. 2 (b), the first rotating element 110 may pivot about the first rotating axis passing through the proximal end 111 in a clockwise direction and the sliding element 115 may be guided to slide along the elongated opening 125 from the first closed end 1251 towards the second open end 1252. In this way, the rotation motion may be transmitted from the first rotating element 110 to the second rotating element 120, so that the second rotating element 120 that may be connected to the main switch of the switchgear module 10 may be driven to rotate in a second clockwise direction about the second rotational axis passing through the second rotating point 128. The second rotational axis may thus be in parallel, but not identical, to the first rotational axis.
By further rotating the operating element 160 for switching the switchgear module 10 to the TEST-mode at the third 135° angular position 163, as shown in Fig. 1 (c) and Fig. 2 (c), the sliding element 115 may further be guided to slide along the elongated opening 125 to the second open end 1252. As the rotational motion of the first rotating element 110 may still be transmitted or transferred to the second rotating element 120, the rotation of the coupled first and second rotating elements 110, 120 may be synchronized.
The third 135° angular position 163 shown in Fig. 1 (c) and Fig. 2 (c) may also be set as the closed angular position for the interlocking mechanism which may follow or be transited to, but be separated from, the switching mechanism for the switchgear module 10. By further rotating the operating element 160 over the 135° angular position 163, the connection between the first and second rotating elements 110, 120 may end, since the sliding element 115 may slide off the elongated opening 126. The rotational transmission between the first and second rotating elements 110, 120 may be interrupted. The mode of the operation of the switchgear module 10 may be kept at the TEST-mode. However, the switchgear module 10 may further be secured inside the compartment.
Until further rotating the operating element 160 for releasing the switchgear module 10 at the open 180° angular position 164, as shown in Fig. 1 (d) and Fig. 2 (d), the first rotating element 110 may rotate freely until the sliding element 115 of the first rotating element 110 may come into contact or collide with the interlocking element 200 at the interlocking pin 215. The interlocking element 200 may be a rocker switch. The rotational motion of the first rotating element 110 may be transmitted to the lineal, translational and/or rotational motion of the rocker switch 200, so that the control system may be in the RELEASE-mode to allow the switchgear module 10 releasable or withdrawable from the compartment.
Additionally, the operating element 160 may also rotate in the opposite direction to reverse the rotation of the first pivoting element 110 in the counterclockwise direction. The first rotating element 110 may not in contact with and interact with the interlocking element 200 after leaving the open 180° angular position in Fig. 1 (d) and Fig. 2 (d), and the switchgear module 10 may be locked or secured inside the compartment again. The first rotating element 110 may freely rotate further until the sliding element 115 may interconnect to the second open end 1252 of the elongated opening 125 at the close angular position for the interlocking mechanism and the third 135° angular position 163 for the TEST-mode of the switchgear module 10, as shown in Fig. 1 (c) and Fig. 2 (c). As in the switching mechanism the rotation motion may be transmitted again between the first and second rotating elements 110, 120, the first and second rotating element 110, 120 may further be coupled and rotate synchronized to switch the switchgear module 10 between the various modes of operation, in particular, from the TEST-mode in Fig. 1 (c) and Fig. 2 (c) to the OFF-mode in Fig. 1 (b) and Fig. 2 (b) and further to the ON-mode in Fig. 1 (a) and Fig. 2(a).
By using the Geneva-like drive mechanism with the first and second rotating elements 110, 120, the transition between the driving and non-driving may be performed within a continuous rotation by means of the single operating element 160 to enable two separate switching mechanisms, respectively under the coupled rotation of the driving first rotating element 110 and the driven second rotating element 120 and under the rotation of the freely rotatable first rotating element 110. Further, the freely rotatable first rotating element may further be used as a driving part to interconnect or interact with the interlocking element 200 to actuate the interlocking mechanism requiring a linear force or movement.
As the first and second rotating elements 110 and 120 may, respectively, be designed to be two flat parts that only need to be combined or connected with cost efficient parts such as screws and/or pins, the manufacturing costs for the compact control system 100 for the switchgear module 10 may be significantly reduced.
Fig. 4 shows schematically a flow chart illustrating a method 400 for operating a switchgear module 10 by means of a multi-use control system 100.
In step 410, a first rotating element 110 is connected to an operating element 160 being pivotable between a plurality of angular positions comprising a first group of angular positions 161, 162, 163 and a second group of angular positions 163, 164.
In step 420, the sliding element 115 is interconnected with the elongated opening 125, guided to slide along the elongated opening 125, and a rotational motion is transmitted from the first rotating element 110 to the second rotating element 120 for switching the switchgear module 10 between the plurality of modes of operation, while rotating the operating element 160 between the first group of angular positions 161, 162, 163.
In step 430, the sliding element 115 is disconnected from the elongated opening 125 and the first rotating element 110 is allowed to transmit the rotational motion to the interlocking element 200 for securing or releasing the switchgear module 10, while rotating the operating element 160 between the second group of angular positions 163, 164.
Additionally, the method may further comprise the step 440, in which the operating element 160 may be rotated in an opposite direction for securing the switchgear module 10 to the compartment by disconnecting the first rotating element 110 from the interlocking element 200, interconnecting the sliding element 110 with the elongated opening 125 for transiting the controlling over the interlocking assembly to the controlling over the switching assembly, and guiding the sliding element 110 to slide along the elongated opening 125, and rotating the operating element 160 between the first group of angular positions 161, 162, 163 for switching the switchgear module 10 between the plurality of modes of operation.
