Description

Technical Field

[0001] This utility model relates to the technical field of substations, and in particular to a wiring structure and a box-type substation. Background Technology

[0002] A prefabricated substation, also known as a box-type substation, is a type of electrical equipment that integrates high-voltage switchgear, transformers, low-voltage switchgear, and corresponding protection, control, measurement, and auxiliary facilities into a single enclosed enclosure. Box-type substations are typically arranged in a U-shape, with the medium-voltage compartment, transformer compartment, and low-voltage compartment arranged sequentially. The electrical equipment in the medium-voltage compartment requires cables to be routed to and connected to the electrical equipment in the low-voltage compartment. For example, ring main units (i.e., high-voltage switchgear) and low-voltage distribution components are located in the medium-voltage compartment, while low-voltage switchgear (i.e., low-voltage switchgear) is located in the low-voltage compartment. The ring main units and low-voltage distribution components require cables to be routed and connected to the low-voltage switchgear's monitoring and control devices. Therefore, existing box-type substations require a cabling structure with internal cabling channels that allow cables to pass from the medium-voltage compartment through the intermediate transformer compartment to the low-voltage compartment.

[0003] Existing cable routing structures are generally connected to the upper crossbeam of the box-type substation. When performing cable routing operations, the operator needs to stand at the cable outlet position in the medium-voltage room to insert the cable into the cable routing structure and push the cable forward continuously. However, the existing cable routing structure is generally just a simple cable trough structure, and the cable is generally quite long. During the cable routing process, the front part of the cable is easy to bend and difficult to move forward, making the entire cable routing process quite difficult. Utility Model Content

[0034] To resolve the above technical issues, please refer to [link / reference]. Figures 1 to 4 This utility model proposes a wiring structure for use in prefabricated substations, comprising:

[0035] The cable tray 11 includes a base plate 111, a first side plate 112, and a second side plate 113; the first side plate 112 and the second side plate 113 are respectively fixedly connected to both sides of the base plate 111 in the width direction, and the base plate 111, the first side plate 112, and the second side plate 113 enclose a cable routing channel 114.

[0036] The second side plate 113 has a first wiring opening 1131 and a second wiring opening 1132. The first wiring opening 1131 and the second wiring opening 1132 are located at both ends of the length direction of the second side plate 113, and the first wiring opening 1131, the second wiring opening 1132 and the wiring channel 114 are interconnected.

[0037] The moving part 12 and the driving part 13 are both disposed within the wiring channel 114;

[0038] The moving component 12 includes a slide rail 121, a slider 122, and a cable fixing seat 123. The slide rail 121 is arranged along the length of the base plate 111 and is located on the upper side of the base plate 111. The slider 122 is slidably connected to the slide rail 121, and the cable fixing seat 123 is connected to the slider 122.

[0039] The driving component 13 is fixedly connected to the slider 122 or the cable fixing seat 123, and the driving component 13 is used to drive the slider 122 and the cable fixing seat 123 to move left and right along the slide rail 121.

[0040] It should be noted that, as Figure 1 As shown, the wiring structure 1 of this utility model is disposed on the upper part of the prefabricated substation, and the cable tray 11 is arranged along the length direction of the prefabricated substation. The first wiring opening 1131 is connected to the inlet or outlet end of the prefabricated substation, and the second wiring opening 1132 is connected to the corresponding outlet or inlet end of the prefabricated substation. For ease of description, the first wiring opening 1131 of this utility model is connected to the outlet end of the prefabricated substation (e.g., the installation location of high-voltage switchgear or other power equipment in the prefabricated substation), and the second wiring opening 1132 is connected to the inlet end of the prefabricated substation (e.g., the installation location of low-voltage switchgear or other power equipment in the prefabricated substation).

[0041] To further explain, when threading the cable, the operator passes the cable sequentially through the outlet end and the first cable routing opening 1131, then into the cable routing channel 114, and fixes the cable to the cable fixing seat 123. This allows the end of the cable entering the cable routing channel 114 to be fixedly connected to the slider 122. The driving component 13 then drives the slider 122 and the cable fixing seat 123 along the slide rail 121 towards the second cable routing opening 1132. The cable can slide in a certain direction, allowing it to move towards the second cable routing opening 1132 along with the cable fixing base 123 and the slider 122. When the cable reaches the end of the cable groove 11 away from the first cable routing opening 1131, the operator can remove the cable from the cable fixing base 123 and pull the cable through the second cable routing opening 1132 and the inlet end in sequence, completing one cable threading operation. At this time, the operator can connect the cable to the corresponding power equipment at the inlet end.

[0042] This invention, by setting the moving component 12 and the driving component 13 within the cable routing channel 114, serves to fix the end of the cable and guide the cable to move along the path of the slide rail 121, avoiding bending of the front end of the cable during the cable threading process, reducing the difficulty of cable threading, improving threading efficiency, and solving the problem that the existing cable routing structure of box-type substations is prone to bending of the front end of the cable during the threading process, making it difficult to continue moving forward and resulting in a high degree of difficulty in the threading process.

[0043] Specifically, the slide rail 121 can be fixedly connected to the upper surface of the base plate 111, or the two sides of the slide rail 121 in the width direction can be fixedly connected to the side walls opposite to the first side plate 112 and the second side plate 113 respectively. Of course, other fixing structures (such as fixing plates) can also be provided in the wiring channel 114 for installing and fixing the slide rail 121.

[0044] Please see Figures 4 to 5 Furthermore, the moving component 12 also includes a guide wheel 124 and a rotating shaft 125; one end of the rotating shaft 125 is fixedly connected to the bottom end face of the slider 122, and the other end of the rotating shaft 125 is rotatably connected to the guide wheel 124, and the rotation axis of the guide wheel 124 is perpendicular to the base plate 111.

[0045] The slide rail 121 has a groove 1211, which is opened along the length of the slide rail 121. The guide wheel 124 is in rolling connection with the slide rail 121 within the groove 1211.

[0046] By setting the guide wheel 124 in the slide groove 1211 and rollingly connecting it with the slide rail 121, and setting the rotation axis of the guide wheel 124 perpendicular to the base plate 111, the slide groove 1211 limits the movement path of the guide wheel 124, so that the slider 122 and the cable fixing seat 123 can drive the cable to move along the slide groove 1211 at the same time, avoiding the slider 122 from lateral deviation during movement.

[0047] Furthermore, compared with the sliding friction coefficient when the slider 122 is directly slidably connected to the slide rail 121, the rolling friction coefficient when the guide wheel 124 is slidably connected to the slide groove 1211 is smaller, which makes the slider 122 move along the slide rail 121 more easily, and at the same time reduces the degree of sliding wear between the slider 122 and the slide rail 121.

[0048] Please see Figure 4 and Figure 5Furthermore, the slide rail 121 includes a body portion 1212 and two arc-shaped slide rail portions 1213. The slide groove 1211 is formed on the upper end face of the body portion 1212. The arc-shaped slide rail portions 1213 are arranged along the length direction of the slide rail 121 and are located in the slide groove 1211. The two arc-shaped slide rail portions 1213 are symmetrically arranged on both sides of the width direction of the slide groove 1211.

[0049] One end of the arc-shaped slide section 1213 is fixedly connected to the inner wall of the main body section 1212, and the other end of the arc-shaped slide section 1213 protrudes towards the slide groove 1211.

[0050] The guide wheel 124 is tactilely connected between the two arc-shaped slide sections 1213, and the guide wheel 124 is provided with a concave arc surface that tactilely engages with the arc-shaped slide section 1213.

[0051] By providing two symmetrical arc-shaped slide sections 1213 within the slide groove 1211, and with the guide wheel 124 rotatably connected between the two arc-shaped slide sections 1213, the lateral displacement of the slider 122 during movement can be prevented, thereby improving the stability of the slider 122 during movement and thus improving the stability of the cable during threading.

[0052] To further explain, multiple guide wheels 124 and rotating shafts 125 are provided, and multiple guide wheels 124 and rotating shafts 125 are provided one-to-one along the length direction of the slider 122, which helps to improve the stability of the slider 122 when it moves.

[0053] Please see Figures 4 to 5 Furthermore, the cable fixing base 123 includes a first fixing part 1231, a second fixing part 1232 and a third fixing part 1233;

[0054] The first fixing part 1231 is fixedly connected to the upper end face of the slider 122, one end of the second fixing part 1232 is fixedly connected to the first fixing part 1231, the other end of the second fixing part 1232 is fixedly connected to the third fixing part 1233, and the third fixing part 1233 is fixedly connected to the upper end face of the slider 122.

[0055] The first fixing part 1231 and the third fixing part 1233 are respectively located at both ends of the slider 122 in the width direction;

[0056] The first fixing part 1231, the second fixing part 1232, the third fixing part 1233 and the slider 122 enclose an installation space 1234, and the installation space 1234, the first wiring port 1131, the wiring channel 114 and the second wiring port 1132 are interconnected.

[0057] Specifically, when the cable fixing base 123 is used to fix the cable, the cable can be placed at the upper end of the second fixing part 1232. The installation space 1234 is used to allow cable ties (or other ropes that can tie the cable to the second fixing part 1232) to pass through, so as to fix the cable to the second fixing part 1232. By setting the installation space 1234, the cable can be easily tied.

[0058] To further explain, the first fixing part 1231 and the slider 122 can be fixed by bolts or welding, and the third fixing part 1233 and the slider 122 can also be fixed by bolts or welding.

[0059] To further explain, the second fixing part 1232 has an inverted U-shaped structure.

[0060] To further explain, the driving component 13 can be configured as a pull rope, which can be connected to the left and right ends of the slider 122 respectively. By pulling the driving components 13 at both ends of the slider 122 respectively, the slider 122 can be moved along the slide rail 121.

[0061] Please see Figures 4 to 6 Furthermore, the wire groove 11 also includes a partition plate 115, which is arranged along the length direction of the base plate 111;

[0062] The partition plate 115 is fixedly connected to the first side plate 112 and the second side plate 113 on both sides in the width direction, and the partition plate 115 divides the wiring channel 114 into a first channel 1141 and a second channel 1142. The first wiring opening 1131, the first channel 1141, the second channel 1142 and the second wiring opening 1132 are interconnected.

[0063] Please see Figure 6 The partition plate 115 has clearance spaces 1151 on both sides of its length direction for avoiding the drive member 13, and the two clearance spaces 1151, the first channel 1141 and the second channel 1142 are interconnected.

[0064] Please see Figure 5 and Figure 6The slide rail 121, the slider 122 and the cable fixing seat 123 are respectively provided in twos. The two slide rails 121 are symmetrically connected to the upper and lower end faces of the partition plate 115, and the two sliders 122 are respectively located on both sides of the length direction of the partition plate 115.

[0065] Please see Figure 4 and Figure 6 The driving component 13 includes a first pull-out section 131 and a second pull-out section 132. One end of the first pull-out section 131 is fixedly connected to one of the cable fixing seats 123, and the other end of the first pull-out section 131 passes through one of the clearance spaces 1151 and is fixedly connected to the other cable fixing seat 123. One end of the second pull-out section 132 is fixedly connected to one of the cable fixing seats 123, and the other end of the second pull-out section 132 passes through the other clearance space 1151 and is fixedly connected to the other cable fixing seat 123.

[0066] The first pull-out section 131, the second pull-out section 132, and the two cable fixing seats 123 form a ring structure.

[0067] The wiring channel 114 is divided into a first channel 1141 and a second channel 1142 by setting the partition plate 115. The first channel 1141 can be used for wiring of low-voltage lines (referring to low-current, low-voltage wires, such as the secondary circuit wires mainly used in the box-type substation), and the second channel 1142 can be used for wiring of high-voltage lines (referring to high-voltage, high-current wires, such as the main circuit wires mainly used in the box-type substation). This achieves the effect of separating high-voltage and low-voltage wiring, avoiding interference between high-voltage lines and low-voltage lines, and facilitating the maintenance and management of high-voltage and low-voltage lines.

[0068] By setting the first pull-out section 131, the second pull-out section 132, and the two cable fixing seats 123 to form a ring structure, the first pull-out section 131 and the second pull-out section 132 are arranged around the partition plate 115 and the moving part 12 along the length direction of the cable routing channel 114. At the same time, by placing the two sliders 122 on both sides of the length direction of the partition plate 115, when the first pull-out section 131 or the second pull-out section 132 is pulled out, the two sliders 122 can move in opposite directions at the same time. When the operator is performing the cable threading operation, he / she can move the two sliders 122 to the left and right directions respectively by standing in the same position, thereby improving the efficiency of the cable threading operation.

[0069] Specifically, for example, when performing the cable threading operation (in which case, please refer to...) Figure 6The slider 122 above the partition plate 115 is located near the first cable routing opening 1131, and the slider 122 below the partition plate 115 is located near the second cable routing opening 1132. The operator can fix the cable at the cable fixing seat 123 above the partition plate 115 at the first cable routing opening 1131. By pulling the first pull-out section 131, the slider 122 above the partition plate 115 is moved to the second cable routing opening 1132, allowing the cable to pass through the first channel 1141 to reach the second cable routing opening 1132. At the same time, the slider 122 located below the partition plate 115 can be moved to a position close to the first cable routing opening 1131. The operator can continue to fix another cable at the cable fixing seat 123 below the partition plate 115 at the first cable routing opening 1131. By continuing to pull the first pull-out section 131, the slider 122 below the partition plate 115 is moved to a position close to the second cable routing opening 1132. At this time, the slider 122 located above the partition plate 115 can be moved back to a position close to the first cable routing opening 1131.

[0070] Of course, another operator can be arranged to stand at the second cable routing opening 1132 to receive the cable, and the operator standing at the second cable routing opening 1132 can also move the two sliders 122 to the left and right respectively by pulling the second pull section 132.

[0071] Specifically, the first pull section 131 and the second pull section 132 can be configured as pull ropes or wire ropes, and the outer periphery of the first pull section 131 and the second pull section 132 can be fitted with insulating sleeves.

[0072] In other embodiments, the two ends of the first pull-out section 131 are fixedly connected to the two sliders 122 respectively, and the two ends of the second pull-out section 132 are fixedly connected to the two sliders 122 respectively. The first pull-out section 131, the second pull-out section 132, and the two sliders 122 form a ring structure. When the first pull-out section 131 or the second pull-out section 132 is pulled, the sliders 122 can be pulled directly, avoiding damage to the cable fixing base 123 due to excessive pulling force.

[0073] In other embodiments, the driving element 13 may also be a combination of a motor and a lead screw, with the driving element 13 and the moving part 12 corresponding one-to-one, so as to realize that the slider 122 moves linearly along the slide rail 121.

[0074] Please see Figure 7Furthermore, the partition plate 115 includes a flat plate portion 1152, two connecting portions 1153 and two arc-shaped portions 1154. The flat plate portion 1152 is arranged along the length direction of the bottom plate 111, and the flat plate portion 1152 and the bottom plate 111 are arranged parallel to each other.

[0075] The upper ends of the two connecting parts 1153 are symmetrically connected to the two ends of the flat plate 1152 in the width direction, and the lower ends of the two connecting parts 1153 extend toward the bottom plate 111, respectively. The opposite end faces of the two connecting parts 1153 are fixedly connected to the first side plate 112 and the second side plate 113, respectively.

[0076] The two arc-shaped portions 1154 are symmetrically connected to the two ends of the flat plate portion 1152 along its length, and the opposite end faces of the two arc-shaped portions 1154 are arc surfaces.

[0077] Specifically, the two slide rails 121 are symmetrically connected to the upper and lower end faces of the flat plate portion 1152, and the clearance spaces 1151 are respectively opened at both ends of the length direction of the flat plate portion 1152.

[0078] By providing the connecting part 1153, the connection stability between the partition plate 115 and the first side plate 112 and the second side plate 113 is enhanced; specifically, the two connecting parts 1153 can be fixedly connected to the first side plate 112 and the second side plate 113 respectively by welding or bolting.

[0079] To further explain, by setting the arc-shaped portion 1154, and the opposite end faces of the two arc-shaped portions 1154 being arc surfaces, the first pull-out section 131 or the second pull-out section 132 can smoothly change its direction of movement when passing through the corresponding arc-shaped portion 1154, which helps to reduce the wear of the first pull-out section 131 and the second pull-out section 132.

[0080] Please see Figure 3 and Figure 8 Furthermore, the second side plate 113 is also provided with a maintenance port 1133 that communicates with the wiring channel 114, and the maintenance port 1133 is located between the first wiring port 1131 and the second wiring port 1132.

[0081] The cable tray 11 also includes a maintenance cover plate 116, which is detachably connected to the end of the second side plate 113 away from the first side plate 112. The maintenance cover plate 116 is correspondingly arranged with the maintenance port 1133, and the maintenance cover plate 116 completely covers the maintenance port 1133.

[0082] By providing the maintenance port 1133 and the maintenance cover plate 116, the maintenance cover plate 116 can be removed to expose the maintenance port 1133, and maintenance personnel can perform maintenance and repair on the moving part 12 and the driving part 13 through the maintenance port 1133.

[0083] When no maintenance is required or the prefabricated substation is in operation, installing the maintenance cover plate 116 to cover the maintenance opening 1133 can protect the cables in the cable routing channel 114 and prevent small animals such as rats from entering the cable routing channel 114 through the maintenance opening 1133 and accidentally touching or damaging the cables, thus causing a safety accident.

[0084] Specifically, optionally, the number of maintenance ports 1133 can be multiple, and the multiple maintenance ports 1133 are arranged along the length direction of the second side plate 113.

[0085] More specifically, after the cable passes through the cable routing channel 114, the operator will pull the cable out through the second cable routing opening 1132, which will cause the section of the cable in the cable routing channel 114 to move closer to the second side plate 113. At the same time, the operator can further move the section of the cable in the cable routing channel 114 towards the second side plate 113 through the maintenance opening 1133, thereby avoiding interference between the slider 122 and the cable fixing seat 123 above the partition plate 115 and the cable when they are moved again.

[0086] Furthermore, when threading the cable, manual assistance can be provided by opening the maintenance port 1133 to prevent the cable from getting tangled with the drive unit 13 or interfering with the moving part 12 and getting stuck.

[0087] Please see Figure 1 and Figure 8 This utility model also proposes a prefabricated substation, including the wiring structure 1 described in any one of the above claims, and the prefabricated substation further includes:

[0088] Container 2, which includes a container body 21, an upper crossbeam 22, a medium-pressure chamber partition 23 and a low-pressure chamber partition 24;

[0089] The top of the enclosure 21 is fixedly connected to the upper crossbeam 22 at both ends along its width direction. The medium-pressure chamber partition 23 and the low-pressure chamber partition 24 are fixedly connected inside the enclosure 21. The medium-pressure chamber partition 23 and the low-pressure chamber partition 24 divide the internal space of the enclosure 21 into a medium-pressure chamber 211, a transformer chamber 212 and a low-pressure chamber 213. The medium-pressure chamber 211, the transformer chamber 212 and the low-pressure chamber 213 are distributed sequentially along the length direction of the enclosure 21.

[0090] The cable tray 11 of the wiring structure 1 is fixedly connected to one of the upper crossbeams 22 in the section of the transformer chamber 212. The two ends of the cable tray 11 in the length direction are respectively connected to the medium-voltage chamber 211 and the low-voltage chamber 213. The ends of the first side plate 112 and the second side plate 113 away from the bottom plate 111 are respectively fixedly connected to the lower end face of the upper crossbeam 22, and the second side plate 113 is located on the side of the upper crossbeam 22 facing the transformer chamber 212.

[0091] Please see Figures 8 to 10 The medium-pressure chamber partition 23 has an outlet port 231, and the low-pressure chamber partition 24 has an inlet port 241. The first cable routing port 1131, the outlet port 231 and the internal space of the medium-pressure chamber 211 are connected. The second cable routing port 1132, the inlet port 241 and the internal space of the low-pressure chamber 213 are connected.

[0092] It should be noted that the prefabricated substation also includes power equipment, including high-voltage switchgear, transformers, low-voltage switchgear, etc. The high-voltage switchgear is located inside the medium-voltage compartment 211, the transformer is located inside the transformer compartment 212, and the low-voltage switchgear is located inside the low-voltage compartment 213.

[0093] It should be noted that the cable is led out from the power equipment in the medium-voltage chamber 211, passes through the outgoing cable port 231, the first cable routing port 1131, the cable routing channel 114, the second cable routing port 1132 and the incoming cable port 241 in sequence, and then enters the low-voltage chamber 213, where it can be connected to the power equipment in the low-voltage chamber 213.

[0094] If the wiring structure 1 is fixedly installed at the bottom of the enclosure 21, water accumulation is likely to occur, resulting in high cleaning and maintenance costs and potential safety risks. The prefabricated substation of this invention reduces water accumulation by fixing the wiring structure 1 to the lower end face of the upper crossbeam 22, thus avoiding safety risks caused by water accumulation.

[0095] The prefabricated substation of this utility model, by setting the wiring structure 1 and setting the moving part 12 in the wiring channel 114, allows the end of the cable located in the wiring channel 114 to be clamped on the slider 122 by the cable fixing seat 123. When the driving part 13 drives the slider 122 and the cable fixing seat 123 to move along the slide rail 121, it can simultaneously drive the cable to move along the slide rail 121, avoiding the problem of the front end of the cable bending during the wiring process, reducing the difficulty of wiring the cable, improving the wiring efficiency, and solving the problem that the wiring structure of the existing prefabricated substation is prone to bending of the front end of the cable during the wiring process, making it difficult to continue moving forward and the wiring process is difficult.

[0096] Please see Figures 8 to 11 Furthermore, the container 2 also includes two connecting slots 25, which are symmetrically arranged at both ends of the length direction of the second side plate 113, and the two connecting slots 25 are respectively located at the corners where the second side plate 113 connects to the medium pressure chamber partition 23 and the low pressure chamber partition 24;

[0097] The connecting groove 25 includes a first horizontal plate 251, a second horizontal plate 252 and a vertical plate 253. One end of the vertical plate 253 is fixedly connected to the second side plate 113, and the other end of the vertical plate 253 extends obliquely to be fixedly connected to the corresponding medium-pressure chamber partition 23 or the low-pressure chamber partition 24.

[0098] The first horizontal plate 251 and the second horizontal plate 252 are symmetrically arranged at the upper and lower ends of the vertical plate 253, and the first horizontal plate 251 and the second horizontal plate 252 are respectively arranged to surround the second side plate 113, the vertical plate 253 and the corresponding medium pressure chamber partition 23 or the low pressure chamber partition 24.

[0099] A connecting channel 254 for the cable to pass through is formed between the first horizontal plate 251, the second horizontal plate 252 and the vertical plate 253;

[0100] The first wiring port 1131 and the outgoing wiring port 231 are located in the connecting channel 254 near the medium-pressure chamber partition 23, and the second wiring port 1132 and the incoming wiring port 241 are located in the connecting channel 254 near the low-pressure chamber partition 24.

[0101] Specifically, one end of the vertical plate 253 connected to the second side plate 113 is located between the first wiring port 1131 and the second wiring port 1132, and the other end of the vertical plate 253 away from the second side plate 113 is located on the side of the corresponding outgoing port 231 or the incoming port 241 away from the second side plate 113; the first horizontal plate 251 and the second horizontal plate 252 are respectively located on the upper and lower sides of the corresponding first wiring port 1131 or the second wiring port 1132, and the corresponding outgoing port 231 or the incoming port 241, so that the positions of the first wiring port 1131 and the outgoing port 231 are located in the connecting channel 254 near the medium-pressure chamber partition 23, and the positions of the second wiring port 1132 and the incoming port 241 are located in the connecting channel 254 near the low-pressure chamber partition 24.

[0102] More specifically, the two connecting channels 254, the outgoing port 231, the first cable routing port 1131, the cable routing channel 114, the second cable routing port 1132, the incoming port 241, the internal space of the medium-voltage chamber 211, and the internal space of the low-voltage chamber 213 are interconnected. The cable can pass sequentially from the inside of the medium-voltage chamber 211 through the outgoing port 231, the corresponding connecting channel 254, the first cable routing port 1131, the cable routing channel 114, the second cable routing port 1132, the other corresponding connecting channel 254, and the incoming port 241 before entering the inside of the low-voltage chamber 213.

[0103] By connecting the first wiring port 1131, the second wiring port 1132, the outgoing port 231 and the incoming port 241 respectively in the connecting channel 254, it is possible to prevent impurities or small animals from entering the wiring channel 114 inside the transformer room 212 and causing safety accidents.

[0104] Furthermore, since the internal space of the medium-voltage chamber 211, the outlet, the corresponding connection channel 254, the first cable routing outlet 1131, and the cable routing channel 114 are sequentially connected, when threading the cable, the operator only needs to complete the cable threading operation within the medium-voltage chamber 211 to the cable routing channel 114, without having to repeatedly enter and exit the medium-voltage chamber 211 and the transformer chamber 212. Similarly, since the internal space of the cable routing channel 114, the second cable routing outlet 1132, the corresponding connection channel 254, the outlet outlet 231, and the low-voltage chamber 213 are sequentially connected, the operator receiving the cable only needs to complete the cable threading operation within the low-voltage chamber 213 from the cable routing channel 114 to the low-voltage chamber 213, without having to repeatedly enter and exit the transformer chamber 212 and the low-voltage chamber 213.

[0105] Specifically, the first horizontal plate 251 and the second horizontal plate 252 are right-angled triangles. One right-angled side of the first horizontal plate 251 and the second horizontal plate 252 is fixedly connected to the upper and lower ends of the second side plate 113, respectively. The other right-angled side of the first horizontal plate 251 and the second horizontal plate 252 is fixedly connected to the corresponding medium-pressure chamber partition 23 or the low-pressure chamber partition 24, respectively. The upper and lower ends of the vertical plate 253 are fixedly connected to the hypotenuses of the first horizontal plate 251 and the second horizontal plate 252, respectively.

[0106] Specifically, the connecting groove 25 and the second side plate 113, as well as the connecting groove 25 and the corresponding medium-pressure chamber partition 23 or low-pressure chamber partition 24, can be fixed by welding or by bolts or other structures.

[0107] Please see Figures 9 to 10 Furthermore, the container 2 also includes a medium-pressure chamber sealing plate 26 and a low-pressure chamber sealing plate 27;

[0108] The medium-voltage chamber sealing plate 26 is detachably connected to the end face of the medium-voltage chamber partition 23 away from the transformer chamber 212. The medium-voltage chamber sealing plate 26 covers the outlet port 231 and is provided with a first clearance opening. The first clearance opening is connected to the outlet port 231.

[0109] The low-voltage chamber sealing plate 27 is detachably connected to the end face of the low-voltage chamber partition 24 away from the transformer chamber 212. The low-voltage chamber sealing plate 27 covers the inlet port 241 and is provided with a second clearance opening, which is connected to the inlet port 241.

[0110] Both the first and second clearance openings are used for the cable to pass through. By setting the medium-voltage chamber sealing plate 26 and the low-voltage chamber sealing plate 27, when the cable needs to be threaded, the medium-voltage chamber sealing plate 26 and the low-voltage chamber sealing plate 27 can be removed to facilitate the cable threading. After the threading operation is completed, the medium-voltage chamber sealing plate 26 and the low-voltage chamber sealing plate 27 can be reinstalled, which helps to prevent foreign objects from entering the cable routing channel 114.

[0111] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
