Description

Technical Field

[0001] The present disclosure relates to a busbar module, a method for replacing an electrical device in a device block, and an electrical device. Background Art

[0002] In industrial applications, busbars are mainly used for simplicity and cost savings. The busbars used in a device block or control cabinet can replace the wiring of many electrical devices or device blocks. This reduces the installation work and also reduces the possibility of installation errors.

[0003] The busbar or busbar system is designed using a modular approach, where the wires are mounted on an adapter or busbar module and directly connected to a busbar with a live current, rather than to a standard cable of an individual electrical device.

[0004] However, in the case of repairing the corresponding electrical device in a device block, for example, if the electrical device has to be removed or replaced, usually a plurality of screws have to be loosened and tightened again. Contact of the contact elements can be prevented by a cover and end caps, but this protection can only be ensured if the cover and / or end caps are correctly installed.

[0005] Therefore, there is a need to provide a busbar module that can easily and safely replace an electrical device in a device block.

[0006] This need is met by a busbar module, an electrical device, and a method for replacing an electrical device in a device block described herein. Summary of the Invention

[0048] In the case of a servo drive amplifier, such as a direct current (DC) servo drive amplifier, bus connection technology can be integrated into the electrical device, in other words, integrated into the electrical drive unit itself. Power distribution may require bus connections, such as a DC link and a control voltage source, such as 24V. In addition, further connections from one electrical device to another electrical device must be considered in the overall solution. Further connections can include time-sensitive network (TSN) signals and / or safe torque off (STO) signals. The TSN signals and / or STO signals can be connected individually on the front side of the electric drive device, or the TSN and / or STO signal distribution can be integrated into the bus module.

[0049] The bus module can also be configured to distribute electrical ground from one electrical device to another electrical device. Alternatively, a protective earth (PE) connection can be used to achieve electrical ground. The PE connection can be a screw contact configured to connect at least two electrical devices.

[0050] The busbar module can also be configured for plugging in the next row via a cable, e.g., a cable option for connecting the next row of electrical devices in the device block. Typically, multiple electrical devices (which can also be referred to as drive devices) in a row in the device block together form a "first" device block. Another "second" device block can be, for example, in the next row of the device block, where the second device block can be arranged below the first device block. To connect the second block arranged in the next row, the second block of devices can be connected to the first block of devices, e.g., from the "left" side and / or "right" side of the respective first and second blocks. For example, for power and signals, there may be a connection possibility from the respective electrical devices on one side of the device block arranged in the first row to the respective electrical devices on one side of the device block arranged in the second row. Such a connection can include a single-strand or one cable and at least one plug. The at least one plug can be designed as a corresponding mating connector for the busbar module as described herein. Thus, the plug can be configured to be plugged into the corresponding busbar module of the electrical device arranged at one end of the first device block. Then, another plug can also be used to establish a connection to the second-row devices, and this another plug is directly plugged into the corresponding busbar module of the electrical device arranged at one end of the second device block.

[0051] The stability of the entire servo amplifier block, e.g., formed by multiple electrical device blocks in a row of device blocks, can be achieved by individual screw connections or clamping connections. The threaded connection or clamping connection can be designed as a PE connection. Alternatively, the PE connection can be integrated in the busbar module.

[0052] As described above, the TSN signal and the STO signal can also circulate between electrical devices. Thus, the TSN (1Gbit Ethernet / 4x twisted pair) and STO signal connections may be located on the front of the electrical device. However, the TSN signal connection and the STO signal connection can also be integrated into the busbar module.

[0053] The busbar module can also be configured to loop in and out via a cable at any point in the network. Thus, a cable outlet may be available at the front of the electrical device or at the busbar module. The installation height is limited. Therefore, the cable routing should be parallel to the front (right-angle connectors may be required).

[0054] The busbar module can be assembled to the electrical device without tools. In addition, by using the busbar module as described herein, the replacement of the electrical devices in the device block can be tool-free. This may also apply to the TSN and STO connections.

[0055] A plurality of electric drive devices or electrical equipment in a row of equipment blocks form an electrical equipment block or a "first" block. Another "second" electronic equipment block can be arranged in the next row of equipment blocks, for example, below the "first" block. Electrical connections between the first electrical equipment block and the second electrical equipment block, such as power connections and / or signal connections. The electrical connection can be composed of a single strand or a cable.

[0056] Other advantages of the busbar module as described herein are as follows:

[0057] The busbar module can achieve a shorter installation time. Therefore, the busbar module can be more user-friendly because quick installation of electrical equipment is possible, for example, in the equipment block, and it is possible to quickly replace electrical equipment in the case of maintenance. Therefore, the busbar module can be plugged into the electrical equipment instead of using screw terminals.

[0058] In addition, there may be no possibility of touching the conductive parts. When the busbar module is installed on the electrical equipment, it may be impossible to touch the live parts. However, even if the busbar module is only partially installed or not installed on the electrical equipment, for example, not plugged into the electrical equipment, the conductive parts of the busbar module and the conductive parts of the electrical equipment can be protected from contact. For example, the busbar module can be delivered without the electrical equipment, and vice versa. Therefore, the conductive parts of the busbar module and the electrical equipment can be protected from contact.

[0059] In addition, protection against contact can also exist in the entire assembly of the busbar module, such as plugging and unplugging the busbar module from the electrical equipment.

[0060] Another benefit of the busbar module described here is that no loose parts are required, such as no end caps or the like.

[0061] Figure 1 A schematic perspective view of a plurality of electrical equipment 200, 220, 240, 270 in an equipment block 280 according to an embodiment of the present disclosure is shown. The plurality of equipment 200, 220, 240, 270 or the equipment block 280 can be arranged in a control cabinet ( Figure 1 (not shown). The electrical equipment 200, 220, 240, 270 can be arranged adjacent to each other in the equipment block 280. In particular, the electrical equipment 200, also referred to herein as the first electrical equipment 200, can be arranged in the middle between the second electrical equipment 220 and the third electrical equipment 240. Therefore, the second electrical equipment 220 can be arranged adjacent to the second side end 175 of the first electrical equipment 200, and the third electrical equipment 240 can be arranged adjacent to the first side end 174 of the first electrical equipment 200. The second electrical equipment 220 and the third electrical equipment 240 can be arranged on the opposite side ends 174, 175 of the first electrical equipment 200.

[0062] Each of the electrical devices 200, 220, 240, 270 may include a corresponding busbar module 100, 120, 140, 170. The busbar modules 100, 120, 140, 170 may be arranged at the front end 171 of the corresponding electrical devices 200, 220, 240, 270 and in the upper region 172 of the corresponding electrical devices 200, 220, 240, 270. It should be understood that, as Figure 1 shown, additional electrical devices may be arranged adjacent to the electrical devices 200, 220, 240, 270. Each of the busbar modules 100, 120, 140, 170 may include a DC bus (DC+ / DC-) and a 24V supply voltage (24V / 0V) in one busbar module 100, 120, 140, 170, which will be further described below.

[0063] Figure 2A A schematic perspective view of a first electrical device 200 having a busbar module 100 in an assembled state is shown. The busbar module 100 is connected to the electrical device 200 through contact elements encapsulated in an insulating element 114 in the assembled state, as will be described below. In particular, the busbar module 100 may be configured to be plugged into the electrical device 200. Thus, the busbar module 100 is plugged into the electrical device 200 in the assembled state.

[0064] Figure 2B A schematic exploded view of the Figure 2A electrical device 100 in an unassembled state is shown. In the unassembled state, the busbar module 100 is disconnected from the electrical device 200. In particular, in the assembled state, the busbar module 100 is pulled out of the electrical device 200. The electrical device 200 may include receiving elements 176 on the front end 171 and in the upper region 172 of the electrical device 200. The receiving elements 176 may be configured to receive the busbar module 100.

[0065] Figures 3A to 3C A schematic perspective view of a busbar module 100 according to an embodiment of the present disclosure is shown. The busbar module may be a two-part busbar module 100, wherein a first part 100a of the busbar module 100 is arranged on top of a second part 100b of the busbar module 100. The first part 100a and the second part 100b of the busbar module 100 may be constructed identically. However, the first part 100a and the second part 100b of the busbar module 100 may also exhibit differences, such as with respect to the dimensions of the contact elements (see Figure 4 ) inside the insulating element 114.

[0066] Figure 4 A view shows Figure 3CSchematic perspective view of three connected busbar modules 100. Each busbar module 100 includes two contact elements 105 and an insulating element 114. The insulating element 114 is shown transparently in Figure 4 in order to identify the arrangement of the two contact elements 105 inside the insulating element 114. Each of the two contact elements 105 includes a first terminal 106, a second terminal 107, and a third terminal 108. The first terminal 106, the second terminal 107, and the third terminal 108 are conductively connected to each other. The first terminal 106 and the second terminal 107 are configured to connect the busbar module 100 to another busbar module 120, 140. The third terminal 108 is configured to connect the busbar module 100 to an electrical device 200 (see Figure 1 ).

[0067] Furthermore, the first terminal 106 is configured to receive the second terminal 147 of the contact element 145 of the third busbar module 140, and the second terminal 107 is configured to be insertable into the first terminal 126 of the contact element 125 of the second busbar module 120.

[0068] The busbar module 100 can be designed as a plug-in solution with contact elements 105 (also referred to as connectors). The busbar module 100 as described herein can include at least one contact element 105 for transmitting a DC voltage (also referred to as a DC bus), and at least one contact element 105 for a 24V power supply from one electrical device 100 to another electrical device 120. The busbar module 100 can include a DC bus, where one of the two contact elements 105 can be configured to transmit DC+ voltage power, while the other contact element 105 can be configured to transmit DC- voltage power from the third busbar module 140 through the first busbar module 100 to the second busbar module 120, and vice versa. Alternatively, the busbar module 100 can include a 24V supply voltage bus, where one of the two contact elements 105 can be configured to transmit 24V voltage power, while the other contact element 105 can be configured to transmit 0V voltage power, i.e., configured as a neutral line, from the third busbar module 140 through the first busbar module 100 to the second busbar module 120, and vice versa.

[0069] The two contact elements 105 for the DC voltage and the two contact elements 105 for the 24V power supply can be combined in one mechanical unit (see Figure 3A ). The mechanical unit can be designed as the insulating element 114 as described herein.

[0070] Figure 5 Shows Figure 3CSchematic exploded perspective view of the busbar module 100. The insulating element 114 includes two cavities 115. Each of the two cavities 115 is configured to receive and accommodate one of the two contact elements 105. Each of the two cavities 115 of the insulating element 114 includes a first part 116, a second part 117, and a third part 118, wherein the first part 116 is configured to receive the first terminal 106 of the contact element 105, the second part 117 is configured to receive the second terminal 107 of the contact element 105, and the third part 118 is configured to receive the third terminal 108 of the contact element 105.

[0071] The respective first part 116 of each cavity 115 is located at the first end 101 of the insulating element 114. The respective second part 117 of each cavity 115 is located at the second end 102 of the insulating element 114. The respective third part 118 of each cavity 115 is located at the third end 103 of the insulating element 114. The first end 101 and the second end 102 are arranged opposite to each other.

[0072] By means of the first part 116 of the two cavities 115 and the second part 117 of the two cavities 115, the insulating element 114 is designed to be comb-shaped at the first end 101 of the insulating element 114 and the second end 102 of the insulating element 114.

[0073] The first terminal 106, the second terminal 107, and the third terminal 108 of the contact element 105 are substantially arranged in a plane 119. Figure 5 Two contact elements 105 arranged in parallel are shown, wherein each of the two contact elements 105 can be substantially arranged in its respective plane 119. Therefore, the first part 116, the second part 117, and the third part 118 can also be arranged in the plane 119 of the respective contact element 105. The planes 119 are arranged in parallel and are spaced apart from each other by a certain distance.

[0074] The first terminal 106 of each contact element 105 includes a plurality of first pins 109, in particular four first pins 109 as Figure 5 shown. The pins 109 can be standard pins 109. The second terminal 107 of each contact element 105 includes at least one contact surface 110. The third terminal 108 of each contact element 104 includes at least one second pin 111, in particular two second pins 111 as Figure 5 shown.

[0075] The contact surface 110 can be shaped or designed such that the busbar modules 100, 120, 140, 170 arranged adjacent to each other (see Figure 1 , 7, 9) can be pushed together, and the first terminals 106 of the respective busbar modules 100, 120, 140, 170 can still be in contact with the second terminals 107 of another busbar module 100, 120, 140, 170. This can allow the busbar modules 100, 120, 140, 170 to be further pushed into each other after having reached full contact with their counterparts in the first locking position, for example, until the second locking position. This can be particularly useful on the left - hand side of the overall electrical equipment block 280 (see Figure 1 , 7 , 9) because the busbar module 140 has nothing protruding outside the housing of the respective electrical equipment 240.

[0076] Figure 6A shows Figure 3C a schematic side view of the busbar module 100 of . Two contact elements 105 are arranged in two cavities 115 of an insulating element 114. Each of the two cavities 115 of the insulating element 114 can extend from a first end 101 of the insulating element 114 to a second end 102 of the insulating element 114. The first terminal 106 of the contact element 105 is located in a first part 116 of the respective cavity 115. The second terminal 107 of the contact element 105 is located in a second part 117 of the respective cavity 115.

[0077] The contact element 105 can be designed in a U - shape, where the first terminal 106 of the contact element can define the opening of the U - shape and the second terminal 107 can define the bottom of the U - shape.

[0078] Figure 6B shows Figure 3C a schematic top view of the busbar module 100 of . The first terminal 106 and the third terminal 108 are connected to each other at an angle 112 of substantially 90 degrees. The second terminal 107 and the third terminal 108 are connected to each other at an angle 112 of substantially 90 degrees. The first terminal 106, in particular the contact pin 109 of the first terminal 106, is arranged in the first part 116 of the cavity 115. The second terminal 107, in particular the contact surface 110 of the second terminal 107 is arranged in the second part 117 of the cavity 115. The third terminal 108, in particular the contact pin 111 of the third terminal 108 is arranged in the third part 118 of the cavity 115 (also see Figure 6C). The width of the contact surface 110 of the second terminal 107 can be configured to be capable of transmitting high energy, such as up to 1000V and up to 150A. The total width of the first terminal 106, i.e., the widths of all the contact pins 109 and the corresponding spacing between the contact pins 109 of the first terminal 106, can be the same as the width of the contact surface 110 of the second terminal 107. The total width of the third terminal 108, i.e., the widths of all the contact pins 111 of the third terminal 108 and the corresponding spacing between the contact pins 111, can be less than the total width of the first terminal 106 or the second terminal 107. The total width of the third terminal 108 can be configured to be capable of transmitting less energy than the first terminal 106 or the second terminal 107.

[0079] Figure 6C shows Figure 3C A schematic front view of the busbar module 100. The third terminal 108 of the contact element 105 is located in the third part 118 of the corresponding cavity 115 at the third end 103 of the insulating element 114.

Each of the electrical devices 200, 220, 240, 270 can include a corresponding busbar module 100, 120, 140, 170. The busbar modules 100, 120, 140, 170 can be arranged at the front end 171 of the corresponding electrical devices 200, 220, 240, 270 and in the upper region 172 of the corresponding electrical devices 200, 220, 240, 270. The electrical devices 200, 220, 240, 270 can be arranged adjacent to each other in the device block 280. In particular, the electrical device 200, also referred to herein as the first electrical device 200, can be arranged in the middle between the second electrical device 220 and the third electrical device 240. Thus, the second electrical device 220 can be arranged adjacent to one side of the first electrical device 200, and the third electrical device 240 can be arranged adjacent to the other side of the first electrical device 200, where the second electrical device 220 and the third electrical device 240 can be arranged on opposite sides of the first electrical device 200.

[0081] The busbar modules 100, 120, 140, 170 of the corresponding electrical devices 200, 220, 240, 270 are configured to be rotatably connected to the electrical devices 200, 220, 240, 270 via studs 104. The busbar modules 100, 120, 140, 170 are rotatably connected to the corresponding electrical devices 200, 220, 240, 270 using mounting plates 180 located at the corresponding electrical devices 200, 220, 240, 270. The mounting plates 180 may be located at the upper ends 172 of the corresponding electrical devices 200, 220, 240, 270. If the busbar modules 100, 120, 140, 170 are mounted or plugged into the corresponding devices 200, 220, 240, 270, the mounting plates 180 may include holes for receiving the studs 104.

[0082] The first busbar module 100 is configured to be rotatable about a rotation axis A such that the corresponding first terminals 106 (see Figure 6B ) of the contact elements 105 (see Figure 6B ) are disconnected from the adjacent third electrical device 240, and the corresponding third terminals 108 (see Figure 6B ) are disconnected from the adjacent third electrical device. If the busbar module 100 is rotated about the rotation axis A by approximately 90 degrees (see also Figure 13B ), the contact elements 105 (see Figure 6B ) are disconnected from the electrical device 200.

[0083] Figure 8 A schematic side view of the busbar module 100 according to an Figure 7 embodiment is shown. The insulating element 114 of the busbar element 100 includes four cavities 115. The busbar module 100 includes four contact elements (see Figure 4 ), with a first pin 109 located at the first terminal of the contact element, where the first pin 109 is located within the corresponding cavity 115 at the first part 116 of the cavity 115. The contact element also includes a contact surface 110 at the second terminal of the contact element, where the contact surface 110 is located within the corresponding cavity 115 at the second part 117 of the cavity 115. Two of the four contact elements are configured to distribute high-voltage power, particularly DC voltage power having at least 300V, preferably up to 1000V, and the other two of the four contact elements are configured to distribute low-voltage power, particularly 24V, preferably up to 120V.

[0084] The rotation axis A is arranged in the region 179 of the second terminal, particularly in the region 179 of the contact surface 110 of the contact element, such that the rotation axis A intersects the contact surface 110 perpendicularly. Thus, the rotation axis A is arranged perpendicular to the second terminal or the second surface 110.

[0085] The axis of rotation A is designed by means of at least one stud 104. At least one stud 104 projects from the insulating element 114 in a direction perpendicular to the contact surface 110 of the contact element. In particular, the busbar module 100 may include two studs 104. The first stud 104 may project from the top surface 177 of the insulating element 114. The second stud 104 may project from the bottom surface 178 of the insulating element 114.

[0086] Figure 9 A schematic perspective view of electrical devices 200, 220, 240, 270 in a device block 280 according to another embodiment of the present disclosure is shown. A plurality of devices 200, 220, 240, 270 or device blocks 280 may be arranged in a control cabinet ( Figure 9 not shown). Each of the electrical devices 200, 220, 240, 270 may include a respective busbar module 100, 120, 140, 170. The busbar modules 100, 120, 140, 170 may be arranged at the front end 171 of the respective electrical devices 200, 220, 240, 270 and in the upper region 172 of the respective electrical devices 200, 220, 240, 270. The electrical devices 200, 220, 240, 270 may be arranged adjacent to each other in the device block 280. In particular, the electrical device 200, also referred to herein as the first electrical device 200, may be arranged in the middle between the second electrical device 220 and the third electrical device 240. Thus, the second electrical device 220 may be arranged adjacent to one side of the first electrical device 200, and the third electrical device 240 may be arranged adjacent to the other side of the first electrical device 200, wherein the second electrical device 220 and the third electrical device 240 may be arranged on opposite sides of the first electrical device 200.

[0087] Figure 10A A schematic perspective view of the busbar module 100 is shown, Figure 10B showing a perspective view of the electrical device 200 according to an Figure 9 embodiment. The busbar module 100 of the corresponding electrical device 200 is configured to be slidably connected to the electrical device 200 by means of at least one slide rail 113 ( Figure 10A ). The slide rail 113 of the busbar module 100 may project from the insulating element 114 in the same direction as the third terminals 108 of at least two contact elements 105 (see Figure 6B ).

[0088] The busbar module 100 is movably connected to the corresponding electrical device 200 by means of at least one respective slide rail 181 located at the corresponding electrical device 200. If the busbar module 100 is installed or plugged into the corresponding device 200 ( Figure 10B ), the corresponding slide rail 181 may be configured to receive the slide rail 113 of the busbar module 100.

[0089] The busbar module 100 of the electrical device 200 can be displaced in the axial direction D, where the axial direction D can point from the first side end 174 of the electrical device 200 to the second side end 175 of the electrical device 200. In other words, the busbar module 100 is configured to be slidably connected to the electrical device 200 in the axial direction D from the first terminal 106 to the second terminal 107 of each of at least two contact elements 105 by means of at least one slide rail 113 (see Figure 10A ).

[0090] Figure 11 A schematic perspective view of the busbar module 100 including the socket 182 is shown. The busbar module can be configured to receive the socket 182. The socket 182 can be designed as a 24V feed-in module. The socket 182 can be plugged directly into the busbar module 100, so that no additional connectors need to be provided on the electrical device 200. The socket can include two ports 183, 184 for connecting the corresponding wires for 24V and 0V connections. The socket 182 can be additionally fixed to the insulating element 114 using the fixing plate 185. The fixing plate 185 can stabilize the plug-in socket 182 to the insulating element 114.

[0091] Figure 12A A schematic perspective view of the electrical devices 200, 220, 240 in the device block 280 according to Figure 1 is shown. A plurality of devices 200, 220, 240 or device blocks 280 can be arranged in a control cabinet ( Figure 12A not shown in the figure). Each of the electrical devices 200, 220, 240 can include a corresponding busbar module 100, 120, 140. The busbar modules 100, 120, 140 can be arranged at the front end 171 of the corresponding electrical devices 200, 220, 240 and in the upper region 172 of the corresponding electrical devices 200, 220, 240. The electrical devices 200, 220, 240 can be arranged adjacent to each other in the device block 280. In particular, the electrical device 200, also referred to herein as the first electrical device 200, can be arranged in the middle between the second electrical device 220 and the third electrical device 240. Thus, the second electrical device 220 can be arranged adjacent to one side of the first electrical device 200, and the third electrical device 240 can be arranged adjacent to the other side of the first electrical device 200, where the second electrical device 220 and the third electrical device 240 can be arranged on opposite sides of the first electrical device 200. If the first electrical device 200 is to be replaced in the Figure 12A device block 280, the following steps shown in Figures 12B to 12G must be performed.

[0092] Figures 12B to 12GA schematic diagram showing the result of the process steps of a method 300 for replacing an electrical device 200 in a device block 280 is shown in perspective view.

[0093] First, as Figure 12B shown, the first busbar module 100 of the first electrical device 200 may have to be pulled out from the first electrical device 200. Accordingly, the first electrical device 200 can be disconnected from the second electrical device 220 and the third electrical device 240 arranged adjacent thereto.

[0094] In Figure 12C the next step shown, the second busbar module 120 of the second electrical device 220 may have to be pulled out from the second electrical device 220. This step can provide sufficient space to move the first electrical device 200 out of the device block 280 in the axial direction C. The axial direction C can point from the rear end 173 of the first electrical device 200 to the front end 171 of the first electrical device 200. Figure 12D The result of removing the first electrical device 200 from the device block 280 is shown.

[0095] After removing the first electrical device 200 from the device block 280, a fourth electrical device 260 can be inserted into the device block 280, see Figure 12E . The fourth electrical device 260 can be different from the first electrical device 200. The fourth electrical device 260 can be inserted into the device block 280 at the same position as the first electrical device 200. Accordingly, the fourth electrical device 260 can be arranged in the middle between the second electrical device 220 and the third electrical device 240.

[0096] Figure 12F and 12G show schematic diagrams of the result of connecting the fourth electrical device 260 to the second electrical device 220 and the third electrical device 240, where the fourth electrical device 260 has replaced the first electrical device 200 in the device block 280. To connect the fourth electrical device 260 to the second electrical device 220 and the third electrical device 240, the second busbar module 120 can be plugged into the second electrical device 220, see Figure 12F .

[0097] Finally, the first busbar module 100 can be plugged into the fourth electrical device 260 to connect the fourth electrical device 260 to the second electrical device 220 and the third electrical device 240 through the first busbar module 100. It should be understood that a new busbar module can also be used to replace the first busbar module 100 of the first electrical device 200 to connect the fourth electrical device 260 to the second electrical device 220 and the third electrical device 240. This also applies to each busbar module. Accordingly, the first electrical device 200 has been replaced by the fourth electrical device 260 in the device block 280. SeeFigure 12G , the first busbar module 100 connects the fourth electrical device 260 to the second electrical device 220 and the third electrical device 240 in the device block 280.

[0098] Figure 13A Shows a schematic perspective view of the electrical devices 200, 220, 240 in the device block 280 according to Figure 7 an embodiment. A plurality of devices 200, 220, 240 or the device block 280 may be arranged in a control cabinet ( Figure 13A not shown in the figure). Each of the electrical devices 200, 220, 240 may include a corresponding busbar module 100, 120, 140. The busbar modules 100, 120, 140 may be arranged at the front end 171 of the corresponding electrical devices 200, 220, 240 and in the upper region 172 of the corresponding electrical devices 200, 220, 240. The electrical devices 200, 220, 240 may be arranged adjacent to each other in the device block 280. In particular, the electrical device 200, also referred to herein as the first electrical device 200, may be arranged in the middle between the second electrical device 220 and the third electrical device 240. Thus, the second electrical device 220 may be arranged adjacent to one side of the first electrical device 200, and the third electrical device 240 may be arranged adjacent to the other side of the first electrical device 200, wherein the second electrical device 220 and the third electrical device 240 may be arranged on opposite sides of the first electrical device 200. If it is necessary to replace the first electrical device 200 in the Figure 13A device block 280 of, the following steps shown in Figures 13B to 13G must be performed.

[0099] Figures 13B to 13G A schematic diagram shows the result of the process steps of the method 400 for replacing the electrical device 200 in the device block 280 in perspective view.

[0100] First, as shown in Figure 13B , the second busbar module 120 of the second electrical device 220 may have to be rotated, particularly counterclockwise by an angle of approximately 90 degrees about the axis of rotation A (see Figure 8 ). Thus, the second electrical device 220 can be disconnected from the adjacent first electrical device 200. In particular, the first terminal of the corresponding contact element of the second busbar module 120 can be disconnected from the second terminal of the corresponding contact element of the first busbar module 100 of the first electrical device 200. In addition to the effect of disconnecting the second electrical device 220 from the first electrical device 200, this step can provide sufficient space to remove the first electrical device 200 from the device block 280 in the axial direction C. The axial direction C can point from the rear end 173 of the first electrical device 200 to the front end 171 of the first electrical device 200.

[0101] In Figure 13C the next step shown, the first busbar module 100 of the first electrical device 200 may have to be rotated, in particular by an angle of approximately 90 degrees counterclockwise about the axis of rotation A (see Figure 8 ). As a result, the first electrical device 200 can be disconnected from the adjacent third electrical device 240 arranged. Specifically, the first terminals of the respective contact elements of the first busbar module 100 can be disconnected from the second terminals of the respective contact elements of the third busbar module 140 of the third electrical device 240.

[0102] Figure 13D A schematic view showing the result of removing the first electrical device 200 from the device block 280 is shown.

[0103] After removing the first electrical device 200 from the device block 280, a fourth electrical device 260 including a fourth busbar module 160 can be inserted into the device block 280, see Figure 13E . The fourth electrical device 260 can be different from the first electrical device 200. The fourth electrical device 260 can be inserted into the device block 280 at the same position as the first electrical device 200. Thus, the fourth electrical device 260 can be arranged in the middle between the second electrical device 220 and the third electrical device 240.

[0104] Figure 13F and 13G A schematic view showing the result of connecting the fourth electrical device 260 to the second electrical device 220 and the third electrical device 240, where the fourth electrical device 260 has replaced the first electrical device 200 in the device block 280.

[0105] To connect the fourth electrical device 260 to the third electrical device 240, the fourth busbar module 160 may have to be rotated, in particular by an angle of approximately 90 degrees clockwise about the axis of rotation A (see Figure 8 ). As a result, the fourth electrical device 260 can be connected to the adjacent third electrical device 240. Specifically, the first terminals of the respective contact elements of the fourth busbar module 160 can be connected to the second terminals of the respective contact elements of the third busbar module 140 of the third electrical device 240, see Figure 13F . It should be understood that the busbar module 100 of the first electrical device 200 can also be used to replace the fourth busbar module 160 of the fourth electrical device 260 to connect the fourth electrical device 260 to the second electrical device 220 and the third electrical device 240. For this purpose, before rotating the busbar module, the busbar module 100 can be removed or pulled out from the first electrical device 200 and plugged into the fourth electrical device 260. This also applies to each busbar module.

[0106] To connect the fourth electrical device 260 to the second electrical device 220, the second busbar module 120 can be rotated, in particular by an angle of approximately 90 degrees clockwise about the axis of rotation A (see Figure 8 ). As a result, the second electrical device 220 can be connected to the fourth electrical device 260 arranged adjacent thereto. Specifically, the first terminals of the respective contact elements of the second busbar module 120 can be connected to the second terminals of the respective contact elements of the fourth busbar module 160 of the fourth electrical device 260, see Figure 13G .

[0107] Thus, the first electrical device 200 has been replaced by the fourth electrical device 260 in the device block 280, see Figure 13G . The fourth electrical device 260 can be connected to the second electrical device 220 and the third electrical device 240 via the fourth busbar module 160.

[0108] Figure 14A Fig. shows a schematic perspective view of the electrical devices 200, 220, 240; 270 in the device block 280 according to the embodiment of Fig. 10. A plurality of devices 200, 220, 240, 270 or device blocks 280 can be arranged in a control cabinet ( Figure 14A not shown). Each of the electrical devices 200, 220, 240, 270 can include a respective busbar module 100, 120, 140, 170. The busbar modules 100, 120, 140, 170 can be arranged at the front end 171 of the respective electrical devices 200, 220, 240, 270 and in the upper region 172 of the respective electrical devices 200, 220, 240, 270. The electrical devices 200, 220, 240, 270 can be arranged adjacent to each other in the device block 280. In particular, the electrical device 200, also referred to herein as the first electrical device 200, can be arranged in the middle between the second electrical device 220 and the third electrical device 240. Thus, the second electrical device 220 can be arranged adjacent to one side of the first electrical device 200, and the third electrical device 240 can be arranged adjacent to the other side of the first electrical device 200, wherein the second electrical device 220 and the third electrical device 240 can be arranged on opposite sides of the first electrical device 200. If it is necessary to replace the first electrical device 200 in the Figure 14A device block 280 of, then the following steps shown in Figures 14B to 14G may have to be performed.

[0109] Figures 14B to 14G Fig. shows a schematic diagram of the result of the process steps of the method 500 for replacing the electrical device 200 in the device block 280 in perspective form.

[0110] First, as shown in Figure 14BAs shown, the second busbar module 120 of the second electrical device 220 may have to slide or move in the axial direction D such that the second electrical device 220 can be disconnected from the adjacent first electrical device 200. In particular, the first terminals of the respective contact elements of the second busbar module 120 of the second electrical device 220 can be disconnected from the second terminals of the respective contact elements of the first busbar module 100 of the first electrical device 200. The axial direction D can point from the first side end 174 of the electrical devices 200; 220, 240, 270 to the second side end 175 of the electrical devices 200, 220, 240, 270. In addition to the effect of disconnecting the second electrical device 220 from the first electrical device 200, this step can provide sufficient space to remove the first electrical device 200 from the device block 280 in the axial direction C once the first electrical device 200 has been disconnected from the third electrical device 240. The axial direction C can point from the rear end 173 of the first electrical device 200 to the front end 171 of the first electrical device 200.

[0111] In some embodiments, the second busbar module 120 of the second electrical device 220 may have to further slide or shift in the axial direction D together with the fifth busbar module 170 of the fifth electrical device 270 in order to have sufficient space to remove the first electrical device 200 from the device block 280 in the axial direction C. The fifth electrical device 270 can be arranged adjacent to the second electrical device 220.

[0112] In Figure 14C In the next step shown, the first busbar module 100 of the first electrical device 200 may have to slide or move in the axial direction D such that the first electrical device 200 can be disconnected from the adjacent third electrical device 240. Specifically, the first terminals of the respective contact elements of the first busbar module 100 of the first electrical device 200 can be disconnected from the second terminals of the respective contact elements of the third busbar module 140 of the third electrical device 240. Figure 14D The result of removing the first electrical device 200 from the device block 280 is shown.

[0113] After removing the first electrical device 200 from the device block 280, a fourth electrical device 260 including a fourth busbar module 160 can be inserted into the device block 280, see Figure 14E . The fourth electrical device 260 can be different from the first electrical device 200. The fourth electrical device 260 can be inserted into the device block 280 at the same position as the first electrical device 200. Thus, the fourth electrical device 260 can be arranged in the middle between the second electrical device 220 and the third electrical device 240.

[0114] Figure 14F and 14GA schematic diagram showing the result of connecting a fourth electrical device 260 to a second electrical device 220 and a third electrical device 240, where the fourth electrical device 260 has replaced the first electrical device 200 in the device block 280.

[0115] To connect the fourth electrical device 260 to the third electrical device 240, the fourth busbar module 160 of the fourth electrical device 260 may have to slide or move in the axial direction E so that the fourth electrical device 260 can be connected to the adjacent third electrical device 240. Specifically, the first terminal of the corresponding contact element of the fourth busbar module 160 of the fourth electrical device 260 can be connected to the second terminal of the corresponding contact element of the third busbar module 140 of the third electrical device 240, as shown in Figure 14F . The axial direction E can point from the second side end 175 of the electrical devices 200; 220, 240, 270 to the first side end 174 of the electrical devices 200, 220, 240, 270. It should be understood that the busbar module 100 of the first electrical device 200 can also be used to replace the fourth busbar module 160 of the fourth electrical device 260 to connect the fourth electrical device 260 to the third electrical device 240. For this purpose, before sliding the busbar module in the axial direction E, the busbar module 100 can be removed or pulled out from the first electrical device 200 and plugged into the fourth electrical device 260. This also applies to each busbar module.

[0116] Finally, the second busbar module 120 of the second electrical device 220 may have to slide or move in the axial direction E so that the second electrical device 220 can be connected to the adjacent fourth electrical device 260. In particular, the first terminal of the corresponding contact element of the second busbar module 120 of the second electrical device 220 can be connected to the second terminal of the corresponding contact element of the fourth busbar module 160 of the fourth electrical device 260. The fourth electrical device 260 can be connected to the second electrical device 220 and the third electrical device 240 through the fourth busbar module 160. Thus, the first electrical device 200 has been replaced by the fourth electrical device 260 in the device block 280, as shown in Figure 14G .

[0117] Figure 15A flowchart is shown, which shows a method 300 for replacing an electrical device 200 in a device block 280 according to an embodiment. At 302, a first busbar module 100 may be pulled out from a first electrical device 200, such that the first electrical device 200 is disconnected from a second electrical device 220 and a third electrical device 240, wherein the first electrical device 200 is arranged in the middle between the second electrical device 220 and the third electrical device 240. At 304, a second busbar module 120 may be pulled out from the second electrical device 220. At 306, the first electrical device 200 may be removed from the device block 280. At 308, a fourth electrical device 260 may be inserted into the device block 280. At 310, the second busbar module 120 may be plugged into the second electrical device 220. At 312, the first busbar module 100 may be plugged into the fourth electrical device 260.

[0118] Figure 16 A flowchart is shown, which shows another method 400 for replacing an electrical device 200 in a device block 280 according to another embodiment. At 402, the second busbar module 120 of the second electrical device 220 may be rotated, such that the second electrical device 220 may be disconnected from the first electrical device 200, wherein the second electrical device 220 may be arranged adjacent to the first electrical device 200 in the device block 280. At 404, the first busbar module 100 of the first electrical device 200 may be rotated, such that the first electrical device 200 may be disconnected from the third electrical device 240, wherein the third electrical device 240 may be arranged adjacent to the first electrical device 200 in the device block 280. At 406, the first electrical device 200 may be removed from the device block 280. At 408, a fourth electrical device 260 including a fourth busbar module 160 may be inserted into the device block 280. At 410, the fourth busbar module 160 of the fourth electrical device 260 may be rotated, such that the fourth electrical device 260 may be connected to the third electrical device 240.
