[0061] refer to Figures 1-3 A modular power distribution room includes a basic module 100, a low-voltage module 200, a high-voltage module 300, and a secondary cable module 400.

[0062] The basic module 100 serves as the installation foundation for the entire modular power distribution room. Its bottom is supported on the ground or other installation foundations, or extends partially below the ground to form a foundation.

[0063] The low-voltage module 200 includes a low-voltage compartment, which is supported on the base module 100.

[0064] The high-voltage module 300 includes a high-voltage chamber, which is supported on the base module 100.

[0065] Specifically, the low-pressure chamber and the high-pressure chamber form a single room structure. Both the low-pressure chamber and the high-pressure chamber include a floor, walls, and a roof. The roofs of the low-pressure chamber and the high-pressure chamber form a structure that is high in the middle and low on both sides to prevent water accumulation.

[0066] Combination Figure 7The basic module 100 includes a support bottom 110 and a support outer wall 120 disposed around the support bottom 110. The support outer wall 120 has a certain thickness, and the floors of the low-pressure chamber and the high-pressure chamber are fixed above the support outer wall 120.

[0067] The walls of the low-voltage and high-voltage compartments form a three-sided enclosure, with the adjacent side of the low-voltage compartment having an open structure, so that the high-voltage and low-voltage compartments together form a complete power distribution room.

[0068] The modular power distribution room involved in this application adopts factory prefabrication for the basic module 100, low-voltage module 200 and high-voltage module 300. The modular production, transportation and splicing technology effectively solves the problems of limited transportation and large on-site construction in traditional power distribution rooms.

[0069] In addition, the modular design also solves the problems of large footprint and long construction period of brick-concrete earthen building power distribution rooms, and solves the problems of limited transportation and large on-site construction of traditional power distribution rooms.

[0070] In addition, the external dimensions can be designed according to the capacity of the power distribution room and the number of lines, which solves the problem of the limited size of traditional prefabricated power distribution rooms.

[0071] The modular power distribution room is equipped with primary cable modules and secondary cable modules 400. The primary cable modules are mainly used for the transmission, distribution and control of electrical energy. They are directly connected to the power supply and electrical equipment in the high-voltage module 300 and the low-voltage module 200, and undertake the task of transmitting and distributing electrical energy. The secondary cable modules 400 are used for controlling, measuring, protecting and indicating signals of the primary cables.

[0072] refer to Figure 4 , Figure 5 Corresponding to the low-voltage module 200 and the high-voltage module 300, the secondary cable module 400 involved in this application includes a low-voltage cable assembly 410 and a high-voltage cable assembly 420. The low-voltage cable assembly 410 is used to connect the working components such as the low-voltage cabinet, transformer and distribution box in the low-voltage module 200, and the high-voltage cable assembly 420 is used to connect the working components such as the high-voltage cabinet, distribution box compartment and rectifier in the high-voltage module 300.

[0073] For ease of understanding, the length direction of the low-pressure chamber and the high-pressure chamber is defined to be consistent with the length direction of the base module 100. The low-pressure chamber and the high-pressure chamber are arranged along the width direction of the base module 100. That is, in the width direction of the base module 100, the low-pressure chamber and the high-pressure chamber are located on both sides of the base module 100 and are connected to each other.

[0074] Combination Figure 9 , Figure 10The low-voltage cable assembly 410 includes a first support portion 401 and a first cable conduit 411. The first support portion 401 is fixed on the low-voltage chamber. Specifically, the first support portion 401 is fixed in the low-voltage chamber formed inside the low-voltage chamber and extends along the width direction of the base module 100 toward the high-voltage module 300.

[0075] The first cable conduit 411 is installed on the first support part 401. A cable channel is formed inside the first cable conduit 411, and secondary cables are laid in the cable channel.

[0076] A first docking part 416 is formed at one end of the first cable conduit 411 near the high-voltage cable assembly 420. The first docking part 416 is connected to the secondary cable laid in the first cable channel.

[0077] Combination Figure 11 , Figure 12 The high-voltage cable assembly 420 includes a second support portion 402 and a second cable conduit 421. The second support portion 402 is fixed on the high-voltage chamber. Specifically, the second support portion 402 is disposed in the high-voltage chamber formed inside the high-voltage chamber.

[0078] The second cable conduit 421 is installed on the second bracket 402. A second docking part 424 is formed on the side of the second cable conduit 421 near the low-voltage cable assembly 410. The second docking part 424 is connected to the secondary cable laid in the second cable conduit.

[0079] After the high-voltage module 300 and the low-voltage module 200 are installed in place, the first docking part 416 and the second docking part 424 are connected to enable the secondary cables in the first cable channel and the second cable conduit to be interconnected, thereby realizing the transmission of signals or power in the high-voltage module 300 and the low-voltage module 200.

[0080] The low-voltage cable assembly 410 and the high-voltage cable assembly 420 in the secondary cable module 400 are prefabricated on the low-voltage module 200 and the high-voltage module 300, respectively. After the high-voltage module 300 and the low-voltage module 200 are assembled on site, the low-voltage cable assembly 410 and the high-voltage cable assembly 420 are connected through the first docking part 416 and the second docking part 424 to realize the rapid connection of the secondary cables. The cable laying is easy and accurate, reducing on-site installation time, reducing operation difficulty, and making on-site construction fast.

[0081] In order to facilitate the stability of the connection between the first docking part 416 and the second docking part 424 and improve the connection efficiency between the high-voltage module 300 and the low-voltage module 200, the first cable conduit 411 is designed to be movable relative to the first support part 401, or the second cable conduit 421 is designed to be movable relative to the second support part 402, so that after the low-voltage module 200 and the high-voltage module 300 are installed on the base module 100, the first cable conduit 411 or the second cable conduit 421 can be moved to the first docking part 416 and the second docking part 424 for connection.

[0082] The first docking part 416 and the second docking part 424 can realize quick plug-in connection of the first cable conduit 411 or the second cable conduit 421, thereby improving connection efficiency.

[0083] The first support 401 and the second support are positioned at the upper part of the high-pressure chamber and the low-pressure chamber to avoid interference with the working parts inside the high-pressure chamber and the low-pressure chamber.

[0084] In some embodiments of this application, the first cable conduit 411 is movable relative to the first bracket portion 401, and the second cable conduit 421 is fixed on the second bracket portion 402.

[0085] After the high-voltage module 300 and the low-voltage module 200 are connected, the first cable conduit 411 is moved towards the second cable conduit 421 to connect with the first docking part 416 and the second docking part 424.

[0086] refer to Figure 5 Specifically, the first cable conduit 411 includes a telescopic section 414. The end of the first cable conduit 411 away from the second cable conduit 421 is fixed to the first support portion 401. As the telescopic section 414 extends or shortens, the end of the first cable conduit near the second cable conduit 421 can move along the first support portion 401.

[0087] The expandable section 414 is specifically a telescopic joint threaded pipe structure formed on the first cable conduit 411, which itself has a certain amount of expansion and contraction along the axial direction to realize the expansion and contraction of the first cable conduit section within a certain range.

[0088] The first support section 401 includes two first support crossbeams 412 arranged opposite to each other. A guide rail section is formed on one side of the two first support crossbeams 412. Positioning protrusions are formed on both sides of the first cable conduit 411 connected to the first support crossbeams 412. The guide rail section is specifically a guide groove structure formed on one side of the first support crossbeam 412. The positioning protrusions are movably connected in the guide rail section.

[0089] Before the low-voltage module 200 is assembled into the base module 100, the first cable conduit 411 moves along the direction away from the high-voltage module 300 until the end of the first docking part 416 does not protrude to the outside of the first support crossbeam 412, so as to avoid interference between the first docking part 416 and the high-voltage module 300 during the installation of the low-voltage module 200.

[0090] After the low-voltage module 200 and the high-voltage module 300 are installed, the operator moves the first cable conduit 411 toward the second cable conduit 421 until the first docking part 416 is connected to the second docking part 424.

[0091] In some other embodiments, in order to facilitate the operator to move the first cable conduit 411, a movable handle 415 is provided on the outer wall of the first cable conduit 411. The movable handle 415 is located at the bottom of the first cable conduit 411, so that the operator can operate it below the first support 401.

[0092] In another embodiment, the second cable conduit 421 is movable relative to the second bracket portion 402, and the first cable conduit 411 is fixed to the first bracket portion 401.

[0093] After the high-voltage module 300 and the low-voltage module 200 are connected and fixed on the base module 100, the second cable conduit 421 is moved toward the first cable conduit 411 to the first docking part 416 and connected to the second docking part 424.

[0094] Specifically, the second cable conduit 421 includes a telescopic section 414. Similar to the previous embodiment, the telescopic section 414 is a telescopic joint or threaded pipe structure formed on the second cable conduit 421. The end of the second cable conduit 421 away from the first cable conduit 411 is fixed on the second support portion 402. As the telescopic section 414 extends or shortens, the end of the second cable conduit 421 close to the first cable conduit 411 can move along the second support portion 402.

[0095] The second support section 402 includes two second support crossbeams 422 arranged opposite to each other. A guide rail section is formed on one side of the two second support crossbeams 422. Positioning protrusions are formed on both sides of the second cable conduit 421 that are connected to the second support crossbeams 422. The guide rail section is a guide groove structure formed on one side of the second support crossbeam 422. The positioning protrusion is movably connected in the guide rail section.

[0096] Before the high-voltage module 300 is assembled into the base module 100, the second cable conduit 421 moves along the direction away from the low-voltage module 200 until the end of the second docking part 424 does not protrude to the outside of the second support crossbeam 422, so as to avoid the second docking part 424 interfering with the high-voltage module 300 during the installation of the low-voltage module 200.

[0097] After the low-voltage module 200 and the high-voltage module 300 are installed, the operator moves the second cable conduit 421 toward the first cable conduit 411 until the first docking part 416 is connected to the second docking part 424.

[0098] refer to Figure 10 In some other embodiments, in order to facilitate the operator to move the first cable conduit 411, a movable handle 415 is provided on the outer wall of the second cable conduit 421 of this application. The movable handle 415 is located at the bottom of the second cable conduit 421, so that the operator can move the second cable conduit 421 from below the second support 402.

[0099] Combining 10, Figure 12 In some embodiments of this application, the first docking part 416 and the second docking part 424 are, respectively, a male connector and a female connector. When the first docking part 416 and the second docking part 424 are connected, the male connector is connected to the female connector.

[0100] In one specific embodiment, the first mating portion 416 is a male connector, and the second mating portion 424 is a female connector. A first insertion guide portion 417 is provided on the peripheral wall of the first mating portion 416, and a second insertion guide portion 425 corresponding to the first insertion guide portion 417 is formed on the inner wall of the second mating portion 424. In one case, the first insertion guide portion 417 is a guide protrusion formed on the peripheral wall of the first mating portion 416, and the second insertion guide portion 425 is a guide recess formed on the peripheral wall of the second mating portion 424, with the guide protrusion and guide recess corresponding to each other.

[0101] Alternatively, the first insertion guide portion 417 may be a guide recess formed on the peripheral wall of the first mating portion 416, and the second insertion guide portion 425 may be a guide protrusion formed on the peripheral wall of the first mating portion 416.

[0102] In some embodiments of this application, a guide ramp is formed on the guide protrusion, and a mating ramp adapted to the guide ramp is formed in the guide recess. Under the guidance of the guide ramp and the mating ramp, the guide protrusion connects to the guide recess, thereby improving the connection efficiency.

[0103] The design of the guide protrusion and guide recess helps to improve the alignment effect of the first docking part 416 and the second docking part 424, plays a guiding role, and facilitates the quick insertion and removal of secondary cables.

[0104] To further improve the stability of the connection between the first docking part 416 and the second docking part 424, the first docking part 416 and the second docking part 424 are designed to have a slot part 418 on one side and a buckle part 426 on the other side. The buckle part 426 and the slot part 418 are detachably connected to achieve a buckle connection between the first docking part 416 and the second docking part 424.

[0105] The slot portion 418 is a groove formed on the outer end face of the first docking portion 416 or the second docking portion 424, and the latch portion 426 is a protrusion formed on the outer end face of the second docking portion 424 or the first docking portion 416. In the installed state, the latch portion 426 is interference-fitted into the slot portion 418 to further limit the first docking portion 416 and the second docking portion 424, and to prevent the first docking portion 416 and the second docking portion 424 from disconnecting under the self-restoring force of the telescopic section 414.

[0106] refer to Figure 7 , Figure 8 In some embodiments of this application, the base module 100 includes a support bottom 110, an intermediate support frame 130 vertically disposed on the support bottom 110, and a support outer wall 120 formed around the support bottom 110 and extending upward. The high-pressure chamber and the low-pressure chamber are connected to the intermediate support frame 130 and the support outer wall 120.

[0107] The bottoms of the high-pressure chamber and the low-pressure chamber are respectively supported on the intermediate support frame 130 and the corresponding side support outer wall 120, and are further fixed to the high-pressure chamber and the base module 100 and the low-pressure chamber and the base module 100 by welding or fastening bolts.

[0108] The primary cable module is set within the basic module 100. The primary cable module includes a primary cable conduit 500, within which a through primary cable channel is formed.

[0109] The two ends of the primary cable conduit 500 extend to the bottom of the high-voltage module 300 and the low-voltage module 200, respectively. The primary cable conduit 500 is provided with primary cables that are connected to the high-voltage module 300 and the low-voltage module 200.

[0110] The intermediate support frame 130 and the outer support wall 120 are arranged to form two cable troughs. The two cable troughs are located below the high-pressure chamber and the low-pressure chamber, respectively. The two ends of the primary cable pipe 500 extend into the two cable troughs.
