[0051] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0052] Please refer to the following: Figures 1 to 4 The rack system provided by the present invention will now be described. The rack system includes rack groups and prefabricated wiring. Each rack group consists of multiple electrical cabinets 100 arranged side-by-side; each electrical cabinet 100 contains power devices, internal wiring, and terminal blocks 300; one end of the internal wiring is connected to the power devices, and the other end is fixed to the terminal blocks 300; the prefabricated wiring is located within the rack group; the prefabricated wiring is connected to the terminal blocks 300 of each electrical cabinet 100.

[0053] The cabinet assembly of the present invention is formed by merging multiple electrical cabinets 100. The multiple electrical cabinets 100 have different functions, each electrical cabinet 100 has its own function, therefore the specific power devices inside each electrical cabinet 100, as well as the internal circuits supplying power to the power devices, are also different.

[0054] For scenarios such as large UPS power systems and data center computer rooms, the parallel setup of multiple electrical cabinets 100 is an existing technology. Therefore, the functions of each electrical cabinet 100 and the design of the power devices installed in each electrical cabinet 100 are also conventional technologies, depending on the application scenario. The specific names of each electrical cabinet 100 will not be described here.

[0055] It should be noted that although the internal wiring in each electrical cabinet 100 is different (internal wiring can be divided into high-voltage wiring and low-voltage wiring, and the differences can be reflected in the number of wire harnesses, wire harness models, etc.), one end of all the internal wiring in each electrical cabinet 100 is fixed to the terminal block 300 of that electrical cabinet 100. That is to say, no matter how the internal wiring in the electrical cabinet 100 is distributed or how it is routed inside the electrical cabinet 100, its final end must be fixed to the terminal block 300.

[0056] The terminal block 300 is similar to an intermediate electrical connector. The prefabricated wiring is connected to the terminal block 300 of each electrical cabinet 100. In other words, the prefabricated wiring is electrically connected to the internal wiring of the corresponding electrical cabinet 100 through the terminal block 300 of each electrical cabinet 100, thereby realizing the electrical connection with the power device.

[0057] The specific installation process for the connection lines of this cabinet system is as follows: Before the cabinet system leaves the factory, the internal wiring in each electrical cabinet 100 is laid out. One end of each internal wire is connected to the corresponding power device, and the other end of all internal wires is fixed to the terminal block 300. During on-site installation, multiple electrical cabinets 100 are first connected in parallel. Then, prefabricated wiring is laid inside the parallel cabinet group. Prefabricated wiring is preferably located above all power devices, and the main body of the prefabricated wiring extends along the parallel direction of multiple electrical cabinets 100. Multiple branch lines are also left in the prefabricated wiring, and these branch lines are connected to the terminal blocks 300 in each electrical cabinet 100.

[0058] The beneficial effects of the cabinet system provided by the present invention are as follows: Compared with the prior art, in the cabinet system of the present invention, each electrical cabinet 100 is provided with a terminal block 300 inside, and one end of the internal wiring is fixed on the terminal block 300. The prefabricated wiring is laid inside each electrical cabinet 100. Before the cabinet system leaves the factory, the internal wiring of each electrical cabinet 100 can be laid first, and the internal wiring of each electrical cabinet 100 can be concentrated on its respective terminal block 300. When the cabinet system is installed on site, it is only necessary to lay the prefabricated wiring in the cabinet group and connect the prefabricated wiring to each terminal block 300. The prefabricated wiring and the internal wiring are electrically connected through the terminal block 300. The wiring operation is quick and convenient, and the installation efficiency of the wiring is improved.

[0059] In some embodiments, the aforementioned cabinet assembly and prefabricated wiring can be adopted as follows: Figure 2 The structure shown is described in the following document. Figure 2 The cabinet group includes a first associated cabinet group 110; the first associated cabinet group 110 has a plurality of electrical cabinets 100 arranged in sequence; the prefabricated wiring includes a first prefabricated main wiring 210; the first prefabricated main wiring 210 is connected to the wiring terminals 300 of each electrical cabinet 100 of the first associated cabinet group 110 respectively.

[0060] The electrical cabinets 100 of the first associated cabinet group 110 are adjacent and arranged sequentially along the cabinet direction. Since there is an association between the electrical cabinets 100 of the first associated cabinet group 110, in other words, there will be other line connections between the electrical cabinets 100 of the first associated cabinet group 110 (between some electrical cabinets 100 or between all electrical cabinets 100). Therefore, the electrical cabinets 100 are arranged sequentially to shorten the length of other lines.

[0061] It should be noted that in this embodiment, the first associated cabinet group 110 may include all the electrical cabinets 100 of the cabinet system, or it may only include a few of the electrical cabinets 100 of the cabinet system. For example, if the number of cabinets in the cabinet system is small, in order to reduce the number of lines, each electrical cabinet 100 can be directly connected to the prefabricated line. In this case, the first associated cabinet group 110 can be understood as the cabinet group, which includes all the electrical cabinets 100. If the number of cabinets in the cabinet system is large, and some of the electrical cabinets 100 need to be electrically connected to each other before being connected to the first prefabricated main line 210, then the first associated cabinet group 110 can be understood as the other electrical cabinets 100 that are directly electrically connected to the first prefabricated main line 210, excluding the aforementioned electrical cabinets 100.

[0062] The number and function of the multiple electrical cabinets 100 in the first associated cabinet group 110 are linked to the design function of the cabinet system. Any cabinet that is directly connected to the first prefabricated main line 210 and has no parallel connection with other electrical cabinets 100 can be considered as the first associated cabinet group 110.

[0063] The first prefabricated main wiring 210 includes multiple main connection harnesses. If the number of cabinets in the cabinet system is large, then the two ends of several main connection harnesses are respectively connected to the terminal blocks 300 of two electrical cabinets 100 of the first associated cabinet group 110. The main body of the above-mentioned main connection harnesses can be wrapped together with straps or tape and extended along the cabinet direction. As long as the end position is not wrapped, it can be connected to the terminal block 300.

[0064] In addition to the aforementioned main connection harnesses, one end of the other main connection harnesses of the first prefabricated main line 210 is connected to the terminal 300 of a certain electrical cabinet 100 in the first associated cabinet group 110, and the other end is connected to the terminal 300 of a certain electrical cabinet 100 other than the first associated cabinet group 110. For this type of main connection harness, the main body can be wound in groups (and the main body can be laid out along the cabinet direction) to avoid the multiple main connection harnesses of the first prefabricated main line 210 from being messy.

[0065] If the number of electrical cabinets 100 in the rack system is large, based on the above implementation method, the rack group and prefabricated wiring can be adopted as follows: Figure 2 The structure shown is described in the following document. Figure 2 The cabinet group also includes a second associated cabinet group 120, which has a plurality of electrical cabinets 100 arranged in sequence; the prefabricated wiring also includes a first prefabricated branch line 211, which is connected to the wiring terminals 300 of each electrical cabinet 100 of the second associated cabinet group 120, and the first prefabricated branch line 211 is also connected to the first prefabricated main line 210.

[0066] Since the cabinet system involves a large number and variety of electrical cabinets 100, and some of these electrical cabinets 100 need to be electrically connected according to their respective functions, the aforementioned electrical cabinets 100 are associated and electrically connected through the first prefabricated branch line 211 to form a second associated cabinet group 120. The second associated cabinet group 120 can be considered as a small cabinet system.

[0067] It should be noted that in this embodiment, the cabinet system has at least one set of second associated cabinet groups 120. If there is only one set of second associated cabinet groups 120, then there is only one set of first prefabricated branch lines 211. If there are two or more sets of second associated cabinet groups 120, then there are two or more sets of first prefabricated branch lines 211. Each set of first prefabricated branch lines 211 is electrically connected to the wiring terminals 300 of each electrical cabinet 100 of the corresponding second associated cabinet group 120, and then electrically connected to the first prefabricated main line 210.

[0068] The electrical cabinets 100 of the second associated cabinet group 120 are also adjacent and arranged sequentially along the cabinet direction, which can shorten the length of the first prefabricated branch line 211 and facilitate the layout of the first prefabricated branch line 211.

[0069] The second associated cabinet group 120 has at least two electrical cabinets 100, each of which is electrically connected to the first prefabricated branch line 211. Specifically, the first prefabricated branch line 211 includes multiple branch wire harnesses, and the two ends of each branch wire harness are respectively connected to the terminals 300 of two electrical cabinets 100 in the second associated cabinet group 120; the main body of the multiple branch wire harnesses is also wrapped together with straps or tape and extends along the cabinet direction, while the end parts are not wrapped but are dispersed and connected to the terminals 300.

[0070] The first prefabricated branch line 211 is also connected to the first prefabricated main line 210. Specifically, one end of one of the main connecting wires of the first prefabricated main line 210 is connected to the terminal 300 of one of the electrical cabinets 100 of the second associated cabinet group 120 (the other end of the main connecting wire is connected to the terminal 300 of one of the electrical cabinets 100 of the first associated cabinet group 110). Through the aforementioned terminal 300 of the second associated cabinet group 120, the first prefabricated branch line 211 and the first prefabricated main line 210 are electrically connected, that is, the first associated cabinet group 110 and the second associated cabinet group 120 are electrically connected.

[0071] If the number of electrical cabinets 100 to be combined in the rack system is small, or the design functions are limited, then the rack system may only include the first associated rack group 110 and the second associated rack group 120. If the number of electrical cabinets 100 to be combined in the rack system is large, or the design functions are extensive, then based on the above implementation method, the rack groups and prefabricated wiring can be adopted as follows: Figure 2 The structure shown is described in the following document. Figure 2 The cabinet group also includes a third associated cabinet group 130, a fourth associated cabinet group 140, and a parallel electrical cabinet 160; the third associated cabinet group 130 has a plurality of electrical cabinets 100 arranged in sequence; the fourth associated cabinet group 140 has a plurality of electrical cabinets 100.

[0072] The prefabricated circuit also includes a first prefabricated parallel circuit 212 and a second prefabricated parallel circuit 213; the first prefabricated parallel circuit 212 is connected to the terminals 300 of each electrical cabinet 100 of the third associated cabinet group 130 and the terminals 300 of the parallel electrical cabinet 160 respectively; the second prefabricated parallel circuit 213 is connected to the terminals 300 of each electrical cabinet 100 of the fourth associated cabinet group 140 and the terminals 300 of the parallel electrical cabinet 160 respectively; after the first prefabricated parallel circuit 212 and the second prefabricated parallel circuit 213 are connected in parallel through the parallel electrical cabinet 160, they are then connected to the first prefabricated main circuit 210 respectively.

[0073] Because the cabinet system involves a large number and variety of electrical cabinets 100, and the functions they perform are complex, and the electrical connections and signal transmission methods between the various electrical cabinets 100 are complex, in order to optimize the wiring method of the electrical system, several electrical cabinets 100 that need to be electrically connected are associated and connected through the first prefabricated parallel line 212 to form a third associated cabinet group 130. Several other electrical cabinets 100 that need to be electrically connected are associated and connected through the second prefabricated parallel line 213 to form a fourth associated cabinet group 140. The third associated cabinet group 130 and the fourth associated cabinet group 140 are electrically connected to the parallel electrical cabinet 160 respectively. Therefore, it can be considered that the third associated cabinet group 130 and the fourth associated cabinet group 140 are connected in parallel through the parallel electrical cabinet 160 and then connected to the first prefabricated main line 210.

[0074] It should be noted that in this embodiment, the parallel electrical cabinet 160 can also be connected in parallel with other associated cabinet groups. In other words, in addition to the third associated cabinet group 130 and the fourth associated cabinet group 140, there can be other associated cabinet groups (but not the first associated cabinet group 110 and the second associated cabinet group 120) connected in parallel with the third associated cabinet group 130 and the fourth associated cabinet group 140.

[0075] The electrical cabinets 100 of the third associated cabinet group 130 are also adjacent and arranged sequentially along the parallel cabinet direction, which can shorten the length of the first prefabricated parallel line 212 and facilitate the layout of the first prefabricated parallel line 212.

[0076] To facilitate wiring and reduce the overall length of prefabricated wiring, in this embodiment, the electrical cabinets 100 of the fourth associated cabinet group 140 are not distributed sequentially, but are set on both sides of the second associated cabinet group 120.

[0077] The third associated cabinet group 130 has at least two electrical cabinets 100, each of which is electrically connected to the first prefabricated parallel line 212. Specifically, the first prefabricated parallel line 212 includes multiple first parallel wire harnesses, the two ends of which are respectively connected to the terminals 300 of two electrical cabinets 100 of the third associated cabinet group 130; the main body of the multiple first parallel wire harnesses is also wrapped together with straps or tape and extended along the cabinet direction, while the end portions are not wrapped but are dispersed and connected to the corresponding terminals 300. One end of the remaining first parallel wire harnesses is connected to the terminal 300 of one of the electrical cabinets 100 in the third associated cabinet group 130, and the other end is connected to the terminal 300 of the parallel electrical cabinet 160. Similarly, the main body of the remaining first parallel wire harnesses is also wrapped together with straps or tape and extended along the direction of the parallel cabinets. The end parts are not wrapped, but are dispersed and connected to the corresponding terminal 300.

[0078] The fourth associated cabinet group 140 has at least two electrical cabinets 100, each of which is electrically connected to the second prefabricated parallel line 213. The specific connection method is the same as that between the third associated cabinet group 130 and the first prefabricated parallel line 212, and will not be described again here.

[0079] The first prefabricated parallel line 212 is also connected to the first prefabricated main line 210. Specifically, one end of one of the main connecting wires of the first prefabricated main line 210 is connected to the terminal 300 of one of the electrical cabinets 100 of the third associated cabinet group 130 (the other end of the main connecting wire is connected to the terminal 300 of one of the electrical cabinets 100 of the first associated cabinet group 110). The electrical connection between the first prefabricated parallel line 212 and the first prefabricated main line 210 is realized through the aforementioned terminal 300 of the third associated cabinet group 130.

[0080] The connection method of the second prefabricated parallel line 213 and the first prefabricated main line 210 is the same as that of the first prefabricated parallel line 212 and the first prefabricated main line 210. Through the above connection method, the third associated cabinet group 130 and the fourth associated cabinet group 140 are connected in parallel, and then electrically connected to the first associated cabinet group 110.

[0081] It should be noted that the various electrical cabinets 100 in this cabinet system need to be electrically connected via high-voltage lines (such as cables) and low-voltage lines (such as data cables). The first prefabricated main line 210, the first prefabricated branch line 211, the first prefabricated parallel line 212, and the second prefabricated parallel line 213 mentioned above are all low-voltage lines. Communication signal transmission between the first associated cabinet group 110, the second associated cabinet group 120, the third associated cabinet group 130, and the fourth associated cabinet group 140 is achieved through these low-voltage lines.

[0082] In addition, each associated cabinet group also requires a high-voltage power line connection. To achieve the above objectives, in some embodiments, the prefabricated wiring can also adopt, for example... Figure 4 The structure shown is described in the following document. Figure 4 The prefabricated wiring also includes a second prefabricated branch line 221 and a third prefabricated branch line 222; the second prefabricated branch line 221 is connected to the terminals 300 of each electrical cabinet 100 of the first associated cabinet group 110, the terminals 300 of each electrical cabinet 100 of the third associated cabinet group 130 and the terminals 300 of the parallel electrical cabinet 160 respectively; the third prefabricated branch line 222 is connected to the terminals 300 of each electrical cabinet 100 of the second associated cabinet group 120, the terminals 300 of each electrical cabinet 100 of the fourth associated cabinet group 140 and the terminals 300 of the parallel electrical cabinet 160 respectively.

[0083] The second prefabricated branch line 221 and the third prefabricated branch line 222 are high-voltage lines. The second prefabricated branch line 221 and the third prefabricated branch line 222 can be combined into the second prefabricated main line. The second prefabricated main line is electrically connected to the wiring terminals 300 of each electrical cabinet 100.

[0084] Since the power lines are cables, they have a large outer diameter and are heavy. In addition, the cabinet system has a large number of cabinets. In order to shorten the length of the second prefabricated main line and facilitate its installation, in this embodiment, the second prefabricated main line is divided into a second prefabricated branch line 221 and a third prefabricated branch line 222. In other words, the power lines are segmented to avoid difficulties in laying and installing the power lines due to their excessive length and weight.

[0085] Of course, the second prefabricated main line is not limited to being divided into two parts. It can also be divided more than twice according to the number of electrical cabinets 100 to be connected, as long as the second prefabricated main line can be connected to the wiring terminals 300 of each electrical cabinet 100.

[0086] The second prefabricated branch line 221 and the third prefabricated branch line 222 have the same wiring direction as the first prefabricated branch line 211. Specifically, the second prefabricated branch line 221 includes multiple second branch wire harnesses, each of which is connected at both ends to the terminals 300 of two electrical cabinets 100. The main body of these multiple second branch wire harnesses is also wrapped together with straps or tape and extends along the direction of cabinet assembly. The ends are not wrapped but are dispersed and connected to the corresponding terminals 300. The third prefabricated branch line 222 has the same wiring method as the second prefabricated branch line 221.

[0087] Since the prefabricated wiring is divided into high-voltage and low-voltage lines, in order to facilitate the separate installation of the high-voltage and low-voltage lines with the terminal block 300, in some embodiments, the terminal block 300 can be adopted as follows: Figure 2 , Figure 3 , Figure 4 and Figure 6 The structure shown is described in the following document. Figure 2 , Figure 3 , Figure 4 and Figure 6 The wiring terminals 300 of each electrical cabinet 100 in the first associated cabinet group 110, the wiring terminals 300 of each electrical cabinet 100 in the second associated cabinet group 120, the wiring terminals 300 of each electrical cabinet 100 in the third associated cabinet group 130, the wiring terminals 300 of each electrical cabinet 100 in the fourth associated cabinet group 140, and the wiring terminals 300 of the parallel electrical cabinet 160 all include: a first low-voltage wiring terminal 310 and a first high-voltage wiring terminal 320.

[0088] The first prefabricated main line 210, the first prefabricated branch line 211, the first prefabricated parallel line 212, and the second prefabricated parallel line 213 are respectively connected to the corresponding first low-voltage terminal 310; the second prefabricated branch line 221 and the third prefabricated branch line 222 are respectively connected to the corresponding first high-voltage terminal 320.

[0089] Please see Figure 2 and Figure 4 The low-voltage terminal block 310 and the high-voltage terminal block 320 have different structures. The low-voltage terminal block 310 is a data cable terminal block with multiple sockets, while the high-voltage terminal block 320 is a wire terminal block with multiple interfaces.

[0090] In some embodiments, the aforementioned electrical cabinets 100 may adopt the following... Figure 5 , Figure 6 and Figure 7 The structure shown is described in the following document. Figure 5 , Figure 6 and Figure 7Each electrical cabinet 100 includes a main cabinet 101 and a prefabricated cabinet 102. Power devices and internal wiring are located inside the main cabinet 101. Low-voltage terminals 310 and high-voltage terminals 320 are fixed to the top of the rear side wall of the main cabinet 101. The prefabricated cabinet 102 is located on top of the main cabinet 101. The rear side wall of the prefabricated cabinet 102 is provided with a first wiring harness channel 103 and a second wiring harness channel 104. The first wiring harness channel 103 and the second wiring harness channel 104 extend along the parallel direction of the multiple electrical cabinets 100. The two sides of the rear side wall of the prefabricated cabinet 102 are respectively provided with a third wiring harness channel 105, which extends in the vertical direction.

[0091] There is a gap between the first wire harness channels 103 of each pair of adjacent prefabricated cabinets 102, which forms a first wire passage space; the power line passes through the first wire harness channel 103, and the power line extends downward through the first wire passage space and connects to the corresponding power terminal 320.

[0092] There is a gap between the second wiring harness channels 104 of each pair of adjacent prefabricated cabinets 102, which forms a second wiring space; the low-voltage line passes through the second wiring harness channel 104, and passes down through the second wiring space into the third wiring harness channel 105, and connects to the corresponding low-voltage terminal 310.

[0093] Each electrical cabinet 100 is divided into a main cabinet 101 and a prefabricated cabinet 102. The main cabinet 101 is mainly used for assembling power devices and laying internal wiring, while the prefabricated cabinet 102 is mainly used for laying prefabricated wiring.

[0094] Before the cabinet system leaves the factory, the internal wiring within each main cabinet 101 is laid out. One end of each internal wire is connected to the corresponding power device, and the other end of all internal wires is fixed to the terminal block 300 of the main cabinet 101. During on-site installation, multiple main cabinets 101 are first connected in parallel, followed by multiple prefabricated cabinets 102, with prefabricated wiring laid within each prefabricated cabinet 102. After the prefabricated wiring is completed, the multiple prefabricated cabinets 102 are then installed onto the multiple main cabinets 101, ensuring that the end of each prefabricated wire harness is inserted into the corresponding terminal block 300.

[0095] Specifically, a second prefabricated main line (i.e., a second prefabricated branch line 221 and a third prefabricated branch line 222) is laid in the first wire harness channel 103. The main body of multiple second branch wire harnesses of the second prefabricated branch line 221 and the main body of multiple third branch wire harnesses of the third prefabricated branch line 222 are wrapped together by straps or tape and laid out along the parallel cabinet direction. The two ends of multiple second branch wire harnesses and the two ends of multiple third branch wire harnesses pass through the corresponding first wire passage space and extend downward to connect with the corresponding high-voltage terminal 320.

[0096] Since the high-voltage terminals 320 connected to the multiple second branch wire harnesses are different, the lengths and installation positions of the multiple second branch wire harnesses are also different. Before installation, the two ends of the multiple second branch wire harnesses of the second prefabricated branch line 221 and the two ends of the multiple third branch wire harnesses of the third prefabricated branch line 222 can be labeled to indicate the electrical cabinet 100 to which the wire harnesses are to be connected and the specific interface of the high-voltage terminal 320, so as to determine the position in the first wire harness channel 103.

[0097] Specifically, a first prefabricated main line 210, a first prefabricated branch line 211, a first prefabricated parallel line 212, and a second prefabricated parallel line 213 are laid in the second wiring harness channel 104, i.e., low-voltage lines are laid. The laying method of the low-voltage lines is the same as that of the high-voltage lines. The main body is wrapped together with straps or tape and extends along the parallel cabinet direction. The two ends of each wire harness pass out from the corresponding second wire passage space, pass downward in the third wiring harness channel 105, and are connected to the corresponding low-voltage terminal 310.

[0098] Similarly, the lengths and locations of each wire harness in the first prefabricated main line 210, the first prefabricated branch line 211, the first prefabricated parallel line 212, and the second prefabricated parallel line 213 are all different. It is also necessary to label both ends of each wire harness in advance to indicate the specific interface of the electrical cabinet 100 and the low-voltage terminal block 310 to which the wire harness will be connected, so as to determine its position in the second wire harness channel 104.

[0099] Because low-voltage cables are lightweight and easily bent, third wiring harness channels 105 are provided on both sides of the back of the prefabricated cabinet 102 to limit the downward movement of the low-voltage cables and prevent them from shaking and affecting signal transmission. High-voltage cables, on the other hand, are heavier and have a rigid outer sheath. Under gravity, their ends can extend downwards on their own, and their outer diameter is larger. Therefore, no wiring harness channel is provided on the back of the prefabricated cabinet 102 to limit the downward extension of the high-voltage cables.

[0100] It should be noted that at least one first wire harness channel 103 and a second wire harness channel 104 are provided on each prefabricated cabinet 102. Due to the large number of wire harnesses in both low-voltage and high-voltage circuits, to avoid collisions between wire harnesses and to prevent them from easily passing through the same wire harness channel, multiple first wire harness channels 103 and / or second wire harness channels 104 are provided within the prefabricated cabinet 102 for electrical cabinets 100 with a large number of connected wire harnesses. Preferably, the multiple first wire harness channels 103 are not interconnected, and the multiple second wire harness channels 104 are also not interconnected.

[0101] For example: Figure 2 As shown, for the second associated cabinet group 120, the various electrical cabinets 100 need to be connected via the first prefabricated branch line 211, and the second associated cabinet group 120 also needs to be connected to the first prefabricated main line 210. Therefore, two sets of first harness channels 102 can be set inside each prefabricated cabinet 102 of the second associated cabinet group 120, wherein the first prefabricated main line 210 is laid in one of the first harness channels 103, and the first prefabricated branch line 211 is laid in the other first harness channel 103. The same situation applies to the third associated cabinet group 130.

[0102] For the fourth associated cabinet group 140, since its electrical cabinets 100 are not arranged adjacently but across cabinets, in addition to setting two first wire harness channels 102 in each prefabricated cabinet 102 of the fourth associated cabinet group 140, a first wire harness channel 103 corresponding to the above-mentioned first wire harness channel 103 can also be set in the prefabricated cabinet 102 that crosses cabinets to lay the second prefabricated parallel line 213.

[0103] In some embodiments, the aforementioned cabinet assembly and prefabricated wiring may also employ, for example... Figure 1 , Figure 2 , Figure 3 and Figure 4 The structure shown is described in the following document. Figure 1 , Figure 2 , Figure 3 and Figure 4 The cabinet group also includes a fifth associated cabinet group 150; the fifth associated cabinet group 150 has a plurality of electrical cabinets 100 arranged in sequence; the prefabricated wiring also includes a prefabricated front-end wiring 214; the prefabricated front-end wiring 214 is connected to the terminal blocks 300 of each electrical cabinet 100 of the fifth associated cabinet group 150 and the terminal blocks 300 of one electrical cabinet 100 of the first associated cabinet group 110 respectively; wherein, the prefabricated front-end wiring 214 is located on the front of the cabinet group, and the prefabricated front-end wiring 214 is a low-voltage wiring.

[0104] For certain power devices, the low-voltage lines connecting them are sensitive and cannot be placed near other low-voltage lines to avoid collisions or signal interference. Therefore, multiple electrical cabinets 100 integrating the aforementioned power devices can be associated as a fifth associated cabinet group 150, and the individual electrical cabinets 100 of the fifth associated cabinet group 150 can be connected via prefabricated front-end wiring 214.

[0105] The prefabricated front-end line 214 is located on the front of the cabinet assembly, while other low-voltage lines are located on the back of the cabinet assembly. The prefabricated front-end line 214 is isolated from other low-voltage lines, so there will be no interference and the transmission performance of the prefabricated front-end line 214 will not be affected.

[0106] In some embodiments, the prefabricated pre-line 214 may also employ, for example... Figure 9 and Figure 10 The structure shown is described in the following document. Figure 9 and Figure 10 Each prefabricated cabinet 102 of the first associated cabinet group 110 and each prefabricated cabinet 102 of the fifth associated cabinet group 150 are provided with a fourth wire harness channel 106. Vertical beams 107 are provided at both ends of the fourth wire harness channel 106. The prefabricated front-end line 214 is shaped in the limiting groove, and the prefabricated front-end line 214 crosses forward across the vertical beams 107 of each two adjacent prefabricated cabinets 102.

[0107] Since the prefabricated front-end line 214 is a low-voltage line, it is relatively light and easy to bend. In order to prevent the prefabricated front-end line 214 from being bent at will, a fourth wire harness channel is set on the front of each prefabricated cabinet 102, so that the prefabricated front-end line 214 can be passed through the fourth wire harness channel, providing wiring space for the prefabricated front-end line 214, thereby ensuring the stability of the signal transmission of the prefabricated front-end line 214.

[0108] In addition, the prefabricated front-end wiring 214 crosses forward across the vertical beams 107 of each pair of adjacent prefabricated cabinets 102, which is equivalent to the prefabricated front-end wiring 214 being tied to each pair of adjacent vertical beams 107. The vertical beams 107 provide support for the prefabricated front-end wiring 214, further ensuring its wiring stability.

[0109] In some embodiments, the prefabricated circuitry described above may also employ, for example... Figure 3 The structure shown is described in the following document. Figure 3 The prefabricated wiring also includes a fourth prefabricated branch line 215 and a fifth prefabricated branch line 223; the fourth prefabricated branch line 215 is connected to the wiring terminals 300 of each electrical cabinet 100 of the first associated cabinet group 110; the fifth prefabricated branch line 223 is connected to the wiring terminals 300 of each electrical cabinet 100 of the first associated cabinet group 110.

[0110] The fourth prefabricated branch line 215 and the fifth prefabricated branch line 223 are respectively located on the front of the cabinet group; the fourth prefabricated branch line 215 is a low-voltage line; and the fifth prefabricated branch line 223 is a high-voltage line.

[0111] Since the first prefabricated main line 210 and the second prefabricated branch line 221 are to be electrically connected to each electrical cabinet 100 of the first associated cabinet group 110, there are many wire harnesses distributed on the back of each electrical cabinet 100 of the first associated cabinet group 110. In order to optimize the wiring method between each electrical cabinet 100 of the first associated cabinet group 110 and reduce the wire harnesses on the back of the first associated cabinet group 110, in this embodiment, the high-voltage line (i.e., the fifth prefabricated branch line 223) and the low-voltage line (i.e., the fourth prefabricated branch line 215) connecting each electrical cabinet 100 of the first associated cabinet group 110 are respectively set on the front of the cabinet group to avoid interference with the wire harnesses on the back and to facilitate the laying of the fourth prefabricated branch line 215 and the fifth prefabricated branch line 223.

[0112] In addition, each electrical cabinet 100 of the first associated cabinet group 110 is directly connected to the first prefabricated main line 210 (weak current line) and the second prefabricated branch line 221 (strong current line), so the first associated cabinet group 110 can be regarded as the main wiring cabinet; and the distribution of the fourth prefabricated branch line 215 and the fifth prefabricated branch line 223 on the front of the cabinet group also makes it easy to perform maintenance operations on each electrical cabinet 100 of the first associated cabinet group 110.

[0113] It should be noted that the fourth prefabricated branch line 215 also passes through the fourth wiring harness channel of each prefabricated cabinet 102 in the first associated cabinet group 110, and the fifth prefabricated branch line 223 passes below the fourth wiring harness channel of each prefabricated cabinet 102 in the first associated cabinet group 110. Moreover, both the fourth prefabricated branch line 215 and the fifth prefabricated branch line 223 extend forward across the vertical beam 107 of each pair of adjacent prefabricated cabinets 102. The vertical beam 107 provides support for the fourth prefabricated branch line 215 and the fifth prefabricated branch line 223, further ensuring the stability of the fourth prefabricated branch line 215 and the fifth prefabricated branch line 223.

[0114] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
