[0026] refer to Figure 1-Figure 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.

[0027] The basic module 100 is the installation base of the entire modular power distribution room, and its bottom is supported on an installation base such as the ground or partially extends below the ground to form a foundation.

[0028] The low-pressure module 200 includes a low-pressure chamber supported on the base module 100 .

[0029] The high-voltage module 300 includes a high-voltage chamber supported on the base module 100 .

[0030] Specifically, the low-pressure chamber and the high-pressure chamber form a room structure, and both the low-pressure chamber and the high-pressure chamber include floors, walls and roofs. The roofs of the low-pressure chamber and the high-pressure chamber form an overall structure with a high middle and low sides to avoid water accumulation.

[0031] Combine Figure 7 The basic module 100 includes a supporting bottom 110 and a supporting outer wall 120 arranged around the supporting bottom 110. The supporting outer wall 120 has a certain thickness, and the floors of the low-pressure chamber and the high-pressure chamber are fixed above the supporting outer wall 120.

[0032] The walls of the low-voltage compartment and the high-voltage compartment are surrounded on three sides, and the adjacent side of the low-voltage compartment and the high-voltage compartment is an open structure, so that the high-voltage compartment and the low-voltage compartment together form a whole distribution room.

[0033] The modular distribution room involved in this application, the basic module 100, the low-voltage module 200 and the high-voltage module 300 are factory-prefabricated, and modular production, transportation and splicing technology are used to effectively solve the problems of limited transportation and large on-site construction volume of traditional distribution rooms.

[0034] In addition, the modular design also solves the difficulties of large footprint and long construction period of brick-concrete earth distribution rooms, and solves the problems of limited transportation and large on-site construction volume of traditional distribution rooms.

[0035] In addition, the external dimensions can be designed according to the capacity of the distribution room and the number of lines, which solves the problem of limited size of traditional prefabricated distribution rooms.

[0036] The modular distribution room is equipped with a primary cable module and a secondary cable module 400. The primary cable module is mainly used for the transmission, distribution and control of electric energy. It is directly connected to the power supply and electrical equipment in the high-voltage module 300 and the low-voltage module 200, and undertakes the task of transmitting and distributing electric energy; the secondary cable module 400 is used to control, measure, protect and indicate signals for the primary cable.

[0037] 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 low-voltage cabinet, transformer, and distribution box and other working parts in the low-voltage module 200, and the high-voltage cable assembly 420 is used to connect the high-voltage cabinet, distribution box compartment, rectifier and other working parts in the high-voltage module 300.

[0038] 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 basic module 100, and the low-pressure chamber and the high-pressure chamber are arranged along the width direction of the basic module 100. That is, in the width direction of the basic module 100, the low-pressure chamber and the high-pressure chamber are respectively located on both sides of the basic module 100 and docked with each other.

[0039] Combine Figure 9 、 Figure 10 The low-voltage cable assembly 410 includes a first bracket portion 401 and a first cable pipe 411. The first bracket portion 401 is fixed on the low-voltage warehouse. Specifically, the first bracket portion 401 is fixed in a low-pressure chamber formed in the low-pressure warehouse and extends along the width direction of the basic module 100 toward the high-voltage module 300.

[0040] The first cable duct 411 is installed on the first bracket portion 401 . A cable channel is formed in the first cable duct 411 , and secondary cables are arranged in the cable channel.

[0041] A first docking portion 416 is formed at one end of the first cable duct 411 close to the high-voltage cable assembly 420 . The first docking portion 416 is connected to a secondary cable arranged in the first cable channel.

[0042] Combine Figure 11 、 Figure 12 The high-voltage cable assembly 420 includes a second bracket portion 402 and a second cable conduit 421. The second bracket portion 402 is fixed on the high-voltage chamber. Specifically, the second bracket portion 402 is arranged in a high-voltage chamber formed in the high-voltage chamber.

[0043] The second cable duct 421 is mounted on the second bracket portion 402 . A second docking portion 424 is formed on one side of the second cable duct 421 close to the low-voltage cable assembly 410 . The second docking portion 424 is connected to the secondary cable arranged in the second cable channel.

[0044] After the high-voltage module 300 and the low-voltage module 200 are installed in place, the first docking portion 416 and the second docking portion 424 are connected to connect the secondary cables in the first cable channel and the second cable channel to each other, thereby realizing the transmission of signals or power in the high-voltage module 300 and the low-voltage module 200.

[0045] 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 portion 416 and the second docking portion 424 to achieve rapid connection of the secondary cables. The cable laying is easy and the cable laying accuracy is high, which reduces on-site installation time, reduces operation difficulty, and speeds up on-site construction.

[0046] Among them, 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 of 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 bracket part 401, or the second cable conduit 421 is designed to be movable relative to the second bracket part 402, so that after the low-voltage module 200 and the high-voltage module 300 are installed on the basic module 100, the first cable conduit 411 or the second cable conduit 421 is moved to the first docking part 416 and the second docking part 424 for connection.

[0047] The first docking portion 416 and the second docking portion 424 can realize a quick plug-in connection of the first cable duct 411 or the second cable duct 421 , thereby improving connection efficiency.

[0048] The first bracket portion 401 and the second bracket are arranged at upper positions in the high-pressure chamber and the low-pressure chamber to avoid interference with working components in the high-pressure chamber and the low-pressure chamber.

[0049] In some embodiments of the present application, the first cable duct 411 is movable relative to the first bracket portion 401 , and the second cable duct 421 is fixed on the second bracket portion 402 .

[0050] After the high-voltage module 300 and the low-voltage module 200 are connected, the first cable conduit 411 is moved toward the second cable conduit 421 until the first docking portion 416 is connected to the second docking portion 424 .

[0051] refer to Figure 5 Specifically, the first cable duct 411 includes a telescopic section 414. One end of the first cable duct 411 away from the second cable duct 421 is fixed to the first bracket portion 401. As the telescopic section 414 is extended or shortened, one end of the first cable duct close to the second cable duct 421 can move along the first bracket portion 401.

[0052] The telescopic section 414 is specifically a telescopic threaded tube structure formed on the first cable pipe 411, which has a certain amount of telescopic extension along the axial direction to achieve telescopic extension of the first cable pipe section within a certain range.

[0053] The first bracket portion 401 includes two first supporting cross frames 412 arranged opposite to each other, and a guide rail portion is formed on the opposite side of the two first supporting cross frames 412. Positioning protrusions are formed on both sides where the first cable duct 411 is connected to the first supporting cross frames 412. The guide rail portion is specifically a guide groove structure formed on one side of the first supporting cross frame 412, and the positioning protrusion is movably connected in the guide rail portion.

[0054] Before the low-voltage module 200 is assembled to the basic module 100, the first cable conduit 411 is moved in a direction away from the high-voltage module 300 until the end of the first docking portion 416 does not protrude to the outside of the first supporting cross frame 412, thereby preventing the first docking portion 416 from interfering with the high-voltage module 300 during the installation of the low-voltage module 200.

[0055] 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 portion 416 is connected to the second docking portion 424 .

[0056] In other embodiments, in order to facilitate the operator to move the first cable pipe 411, a movable handle portion 415 is provided on the outer wall of the first cable pipe 411 of the present application, and the movable handle portion 415 is provided at the bottom of the first cable pipe 411 to facilitate the operator to operate below the first bracket portion 401.

[0057] In another embodiment, the second cable duct 421 is movable relative to the second bracket portion 402 , and the first cable duct 411 is fixed to the first bracket portion 401 .

[0058] After the high-voltage module 300 and the low-voltage module 200 are connected and fixed to the base module 100 , the second cable duct 421 is moved toward the first cable duct 411 to connect with the first docking portion 416 and the second docking portion 424 .

[0059] 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 tube 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 bracket portion 402. As the telescopic section 414 is extended or shortened, the end of the second cable conduit 421 close to the first cable conduit 411 is movable along the second bracket portion 402.

[0060] The second bracket portion 402 includes two second supporting cross frames 422 arranged opposite to each other, and a guide rail portion is formed on the opposite side of the two second supporting cross frames 422. Positioning protrusions are formed on both sides where the second cable duct 421 is connected to the second supporting cross frames 422. The guide rail portion is a guide groove structure formed on one side of the second supporting cross frame 422, and the positioning protrusion is movably connected to the guide rail portion.

[0061] Before the high-voltage module 300 is assembled to the basic module 100, the second cable duct 421 is moved in a direction away from the low-voltage module 200 until the end of the second docking portion 424 does not protrude to the outside of the second supporting cross frame 422, so as to avoid the second docking portion 424 from interfering with the high-voltage module 300 during the installation of the low-voltage module 200.

[0062] 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 portion 416 is connected to the second docking portion 424 .

[0063] refer to Figure 10 In other embodiments, in order to facilitate the operator to move the first cable conduit 411, a movable handle portion 415 is provided on the outer wall of the second cable conduit 421 of the present application. The movable handle portion 415 is provided at the bottom of the second cable conduit 421, which facilitates the operator to operate and move the second cable conduit 421 below the second bracket portion 402.

[0064] Combined with 10, Figure 12 In some embodiments of the present application, one of the first docking portion 416 and the second docking portion 424 is a male connector and the other is a female connector. When the first docking portion 416 and the second docking portion 424 are connected, the male connector is connected to the female connector.

[0065] In a specific embodiment, the first docking portion 416 is a male plug-in connector, the second docking portion 424 is a female plug-in connector, a first plug-in guide portion 417 is provided on the peripheral wall of the first docking portion 416, and a second plug-in guide portion 425 corresponding to the first plug-in guide portion 417 is formed on the inner wall of the second docking portion 424. In one case, the first plug-in guide portion 417 is a guide protrusion formed on the peripheral wall of the first docking portion 416, and the second plug-in guide portion 425 is a guide recess formed on the peripheral wall of the second docking portion 424, and the guide protrusions correspond to the guide recesses one-to-one.

[0066] Alternatively, the first plug-in guide portion 417 may be a guide recess formed on the peripheral wall of the first docking portion 416 , and the second plug-in guide portion 425 may be a guide protrusion formed on the peripheral wall of the first docking portion 416 .

[0067] In some embodiments of the present application, a guiding bevel is formed on the guiding protrusion, and a matching bevel that matches the guiding bevel is formed in the guiding recess. Under the guidance of the guiding bevel and the matching bevel, the guiding protrusion is connected to the guiding recess, thereby improving the connection efficiency.

[0068] The design of the guiding protrusion and the guiding recess is conducive to improving the alignment effect of the first docking portion 416 and the second docking portion 424, plays a guiding role, and is conducive to achieving rapid plugging and unplugging of the secondary cable.

[0069] In order to further improve the stability of the connection between the first docking portion 416 and the second docking portion 424, it is designed that one of the first docking portion 416 and the second docking portion 424 is provided with a slot portion 418, and the other is provided with a buckle portion 426. The buckle portion 426 and the slot portion 418 are detachably connected to achieve a buckle connection between the first docking portion 416 and the second docking portion 424.

[0070] The slot portion 418 is a groove formed on the outer end surface of the first docking portion 416 or the second docking portion 424, and the buckle portion 426 is a convex portion formed on the outer end surface of the second docking portion 424 or the first docking portion 416. In the installed state, the buckle portion 426 is interference-connected to the slot portion 418, further limiting the first docking portion 416 and the second docking portion 424, to prevent the first docking portion 416 and the second docking portion 424 from being disconnected under the action of the self-restoring force of the telescopic section 414.

[0071] refer to Figure 7 、 Figure 8 In some embodiments of the present application, the basic module 100 includes a supporting bottom 110, an intermediate supporting frame 130 vertically arranged on the supporting bottom 110, and a supporting outer wall 120 formed on the periphery of the supporting bottom 110 and extending upward, and the high-pressure chamber and the low-pressure chamber are connected to the intermediate supporting frame 130 and the supporting outer wall 120.

[0072] The bottoms of the high-pressure chamber and the low-pressure chamber are respectively supported on the intermediate support frame 130 and the supporting outer wall 120 on the corresponding side, and the high-pressure chamber and the basic module 100, the low-pressure chamber and the basic module 100 are further fixed by welding or tightening bolts and other structures.

[0073] The primary cable module is disposed in the basic module 100 . The primary cable module includes a primary cable duct 500 . A primary cable channel is formed in the primary cable duct 500 .

[0074] Both ends of the primary cable duct 500 extend to below the high-voltage module 300 and the low-voltage module 200 respectively. Primary cables connected to the high-voltage module 300 and the low-voltage module 200 are arranged in the primary cable duct 500 .

[0075] The middle support frame 130 and the supporting outer wall 120 are arranged to form two cable troughs, which are respectively located below the high-pressure compartment and the low-pressure compartment.
