Description

Technical Field

[0001] The present invention relates to a distribution network operation control system, and more particularly, to a distribution network operation control system based on a novel power system. Background Art

[0002] The power system is divided into the power generation side and the distribution side. The distribution network operation and control system is the most basic part of the distribution side. Common distribution network operation and control systems include equipment such as distribution devices. The current in the distribution network is distributed to thousands of households through the distribution devices in the distribution network operation and control system. The new power system grid form has changed from the traditional power grid dominated by one-way step-by-step transmission to an energy Internet including AC / DC hybrid large power grids, microgrids, local DC power grids and adjustable loads. Therefore, higher requirements are placed on the stability and safety of the distribution network operation and control system. In the traditional distribution network operation and control system, multiple distribution devices are directly installed on the same mounting board. In this way, when staff repair or install a distribution device, they are likely to touch other distribution devices, resulting in reduced stability and safety of the distribution network operation and control system.

[0003] In view of the above reasons, how to prevent staff from touching other distributors when repairing or installing a distributor is exactly the problem considered in this application. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, a distribution network operation control system based on a new power system is provided, in which workers will not touch other distribution devices when repairing or installing a distribution device.

[0005] To achieve the above-mentioned object, the following technical solution is provided: a distribution network operation control system based on a novel power system, comprising a housing, a first mounting plate and a second mounting plate arranged one behind the other fixedly connected to the housing, and a plurality of mounting brackets arranged between the first mounting plate and the second mounting plate and staggered in an alternating manner further connected to the housing;

[0006] The mounting frame includes a first positioning plate connected to the first mounting plate, a second positioning plate connected to the second mounting plate, and a plurality of first positioning rails, wherein two ends of the plurality of first positioning rails are respectively connected to the top and bottom of the first positioning plate and the top and bottom of the second positioning plate;

[0007] The first mounting plate is provided with a plurality of guide plates and a plurality of filling plates. The lowest guide plate of the first mounting plate is fixedly connected to the housing. The top and bottom of the guide plate are provided with positioning grooves that are slidably connected to the first positioning rails. The plurality of filling plates are provided with second positioning rails that are slidably connected to the corresponding positioning grooves. The structure of the second mounting plate is the same as that of the first mounting plate.

[0008] A fan is provided on the inner side of the back side of the shell, which is arranged near the top of the shell. The fan is used to guide the air inside the shell to be discharged out of the shell. A wind shield is fixedly connected to the top of the first mounting plate. The wind shield is fixedly connected to the shell at one end away from the guide plate. The wind shield is used to guide external air to flow from the first positioning plate into the mounting frame.

[0009] In summary, the above technical solution has the following beneficial effects: the positions of the first mounting plate and the second mounting plate are fixed relative to the shell, and the first positioning plate can be arbitrarily set on the first mounting plate through the first positioning rail and the positioning groove connected by the sliding connection. Similarly, the second positioning plate can be set on the second mounting plate at a position corresponding to the first positioning plate through the first positioning rail and the positioning groove connected by the sliding connection. In this way, the position of the mounting bracket can be adjusted by sliding from the side and installed on the first mounting plate and the second mounting bracket. At the same time, the gap between the mounting bracket and the second mounting bracket in the same row is filled with a filling plate, and the filling plate slides and adjusts its position through the second positioning rail and the positioning groove connected by the sliding connection. The gap between the mounting bracket and the second mounting bracket in the same row is filled with a guide plate, thereby improving the stability of the mounting bracket. In this way, the stability and safety of the distribution network operation control system can be guaranteed while ensuring the freedom of setting the mounting bracket.

[0010] Each mounting rack can be regarded as an independent module. Different models of power distribution units can be installed in different mounting racks according to needs. When operating a power distribution unit installed in a mounting rack, only the corresponding mounting rack needs to be operated to remove the internal power distribution unit and operate it. During the operation, it will not affect other mounting racks and the power distribution units installed in them, thus ensuring the stability and security of the distribution network operation control system.

[0011] When the distributor is working, heat is generated to heat the air in the shell. The density of hot air is smaller than that of cold air, so the hot air will be concentrated at the top of the shell, and the cold air will sink, forming a circulation of hot and cold air inside the shell, so that the hot and cold air around the distributor can be continuously convected, improving the heat dissipation capacity. The fan is used to force the air inside and outside the shell to convect and dissipate heat. When the fan is started, the fan set on the top of the shell will first discharge the hot air, which will cause the air pressure inside the shell to drop. In order to maintain the air pressure balance inside the shell, the air outside the shell will enter the shell. Since the top of the first mounting plate is fixedly connected to the windshield, The cold air outside the shell only flows through the first positioning plate, and takes away the heat generated by the distributor when flowing through the distributor. While completing the convection of hot and cold air inside and outside the shell, it can also directly dissipate heat to the distributor, preventing the distributor from being damaged due to overheating, thereby improving the heat dissipation performance. In addition, the mounting brackets are staggered in both the left and right and up and down directions. The hot air below will stagger the distributor above when moving upward, forming an unobstructed convection path. The distributor above will not reduce heat exchange due to the hot air moving from below, thereby improving the heat dissipation efficiency and ensuring the stability and safety of the distribution network operation control system.

[0012] The distributor is one of the basic units of the distribution network operation and control system, and is also the most common core of the distribution equipment. The new power system has put forward higher requirements on the stability and safety of the distribution network operation and control system. However, in the existing technology, multiple distributors are usually installed on the same mounting plate. The spacing between the distributors is too short, which makes it easy for workers to touch other distributors when repairing or installing a distributor. The present invention adopts a modular design and staggers multiple mounting frames. Each distributor is set in a separate mounting frame, so that each mounting frame can maintain the stability and safety of the distributor inside. In this way, when workers repair or install a distributor, they can operate on it separately without worrying about touching other distributors set inside the mounting frame. At the same time, the heat dissipation performance is improved, thereby improving the stability and safety of the distribution network operation and control system. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments. Identical components are denoted by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom," "top," "inner," and "outer" refer to directions toward or away from the geometric center of a particular component, respectively.

[0030] Reference Figure 1-8 As shown, a distribution network operation control system based on a novel power system includes a housing 1, wherein a first mounting plate 2 and a second mounting plate 3 arranged one behind the other are fixedly connected to the housing 1, and a plurality of mounting brackets 4 arranged between the first mounting plate 2 and the second mounting plate 3 and staggered are also connected to the housing 1;

[0031] The mounting frame 4 includes a first positioning plate 41 connected to the first mounting plate 2, a second positioning plate 42 connected to the second mounting plate 3, and a plurality of first positioning rails 49, wherein the ends of the plurality of first positioning rails 49 are respectively connected to the top and bottom of the first positioning plate 41 and the top and bottom of the second positioning plate 42;

[0032] The first mounting plate 2 is provided with a plurality of guide plates 21 and a plurality of filling plates 22. The guide plate 21 at the bottom of the first mounting plate 2 is fixedly connected to the housing 1. The top and bottom of the guide plate 21 are provided with positioning grooves 23 that are slidably connected to the first positioning rails 49. The plurality of filling plates 22 are provided with second positioning rails 24 that are slidably connected to the corresponding positioning grooves 23. The structure of the second mounting plate 3 is the same as that of the first mounting plate 2.

[0033] A fan 13 is provided on the inner side of the back of the housing 1, which is arranged near the top of the housing 1. The fan 13 is used to guide the air inside the housing 1 to be discharged outside the housing 1. A windshield 14 is fixedly connected to the top of the first mounting plate 2. The end of the windshield 14 away from the guide plate 21 is fixedly connected to the housing 1. The windshield 14 is used to guide external air from the first positioning plate 41 into the mounting frame 4.

[0034] The positions of the first mounting plate 2 and the second mounting plate 3 are fixed relative to the shell, and the first positioning plate 41 can be arbitrarily set on the first mounting plate 2 through the first positioning rail 49 and the positioning groove 23 that are slidably connected. Similarly, the second positioning plate 42 can be set on the second mounting plate 3 at the position corresponding to the first positioning plate 41 through the first positioning rail 49 and the positioning groove 23 that are slidably connected. In this way, the position of the mounting bracket 4 can be adjusted by sliding from the side and installed on the first mounting plate 2 and the second mounting plate 3. At the same time, the gap between the mounting bracket 4 and the second mounting bracket 5 in the same row is filled with the filling plate 22, and the filling plate 22 slides and adjusts its position through the second positioning rail 24 and the positioning groove 23 that are slidably connected. The gap between the mounting bracket 4 and the second mounting bracket 5 in the same row is filled with the guide plate 21, thereby improving the stability of the mounting bracket 4. In this way, the stability and safety of the distribution network operation control system can be guaranteed while ensuring that the mounting bracket 4 can be freely set.

[0035] Each mounting rack 4 can be regarded as an independent module. Different types of power distributors can be installed in different mounting racks 4 according to the needs. When operating the power distributor installed in the mounting rack 4, only the corresponding mounting rack 4 needs to be operated to remove the power distributor installed inside and operate it. During the operation, it will not affect other mounting racks 4 and the power distributors installed inside them, thus ensuring the stability and safety of the distribution network operation control system.

[0036] When the distributor is working, heat is generated to heat the air in the shell 1. The density of hot air is smaller than that of cold air, so the hot air will be concentrated at the top of the shell 1, and the cold air will sink, forming a circulation of hot and cold air inside the shell 1, so that the hot and cold air around the distributor can be continuously convected, thereby improving the heat dissipation capacity. The fan 13 is used to force the air inside and outside the shell 1 to convect and dissipate heat. When the fan 13 is started, the fan 13 set on the top of the shell 1 will give priority to exhausting the hot air, which will cause the air pressure inside the shell 1 to decrease. In order to maintain the air pressure balance inside the shell, the air outside the shell 1 will enter the shell 1. Since the top of the first mounting plate 2 is fixedly connected with The windshield 14 and the cold air outside the shell 1 only flow through the first positioning plate 41, and take away the heat generated by the distributor when flowing through the distributor. While completing the convection of hot and cold air inside and outside the shell 1, it can also directly dissipate heat to the distributor, preventing the distributor from being damaged due to overheating, thereby improving the heat dissipation performance. In addition, the mounting brackets 4 are staggered in both the left and right and up and down directions. The hot air below will stagger the distributor above when moving upward, forming an unobstructed convection path. The distributor above will not reduce heat exchange due to the hot air moving from below, thereby improving the heat dissipation efficiency and ensuring the stability and safety of the distribution network operation control system.

[0037] The distributor is one of the basic units of the distribution network operation and control system, and is also the most common core of distribution equipment. The new power system has put forward higher requirements on the stability and safety of the distribution network operation and control system. However, in the existing technology, multiple distributors are usually installed on the same mounting plate. The spacing between the distributors is too short, which makes it easy for staff to touch other distributors when repairing or installing a distributor. The present invention adopts a modular design and staggers multiple mounting frames 4 at the same time. Each distributor is set in a separate mounting frame 4, so that each mounting frame 4 can maintain the stability and safety of the distributor arranged inside. In this way, when staff repair or install a distributor, they can operate on it separately without worrying about touching other distributors set inside the mounting frame 4. At the same time, the heat dissipation performance is improved, thereby improving the stability and safety of the distribution network operation and control system.

[0038] Furthermore, an opening 43 is provided on the first positioning plate 41, and a plurality of guide rails 44 are fixedly connected to the first positioning plate 41. The guide rails 44 are provided between the first positioning plate 41 and the second positioning plate 42 and are fixedly connected to the second positioning plate 42. The plurality of guide rails 44 are connected to the same fixing plate 48, and the fixing plate 48 is used to install the distributor. The fixing plate 48 is fixedly connected to a baffle 45 on the side facing the second positioning plate 42, and the baffle 45 is connected to a spring 46. The spring 46 is fixedly connected to the second positioning plate 42 on the side away from the baffle 45. The first positioning plate 41 is also rotatably connected to a control shaft 47, and the control shaft 47 is connected to the second positioning plate 42. The control shaft 47 is detachably connected to a resistance member 471. The fixing plate 48 includes a first support member 446, and the resistance member 471 is used to limit the first support member 446.

[0039] like Figure 3-4 In the two embodiments shown, the interference members 471 in the adjacent mounting brackets 4 are connected to different positions on the control shaft 47;

[0040] The wires are connected to the distributor arranged on the mounting frame through the opening 43 of the first positioning plate 41. The fixing plate 48 on which the distributor is installed can slide along the guide rail 44. The spring 46 will continuously apply a force to the baffle 45 away from the second positioning plate 42, so that the fixing plate 48 can move toward the first positioning plate 41. The resistance member 471 provided on the control shaft 47 can prevent the fixing plate 48 from moving by resisting the first support member 446. Under the action of the spring 46 and the resistance member 471, the relative position of the fixing plate 48 is not easy to change, and it can be By rotating the control shaft 47, the interference member 471 rotates around the control shaft 47, so that the interference member 471 no longer interferes with the first support member 446. At this time, the fixing plate 48 moves toward the first positioning plate 41 without being interfered with by the first support member 446, and finally extends out of the opening 43, and then the distributor installed on the fixing plate 48 can be operated. After the operation is completed, the fixing plate 48 can be pushed back, and the control shaft 47 is rotated to make the interference member 471 interfere with the first support member 446 again, so that the relative position of the fixing plate 48 is fixed again.

[0041] The resistance members 471 in adjacent mounting frames 4 are connected to different positions on the control shaft 47, so a large gap is left between the distributors in adjacent mounting frames 4. In this way, each individual mounting frame 4 can form an independent protection module. The vibration caused by magnetostriction is mitigated by the suspended guide rails 44 and springs 46. The gap can prevent electromagnetic interference caused by damage to the distributor from affecting the surrounding distributors, thereby maintaining the overall stability and safety of the module and improving the stability and safety of the distribution network operation control system.

[0042] Furthermore, the guide rail 44 includes a plurality of left guide rails 441 provided on the left side of the fixed plate 48 and a plurality of right guide rails 442 provided on the right side of the fixed plate 48, the fixed plate 48 includes a plurality of left movable rings 443 slidably connected to the left guide rail 441 and a plurality of right movable rings 444 slidably connected to the right guide rail 442, the plurality of left movable rings 443 are all fixedly connected to the same second support member 445, the plurality of right movable rings 444 are all fixedly connected to the same first support member 446, the first positioning plate 41 is provided with a through hole 447 provided corresponding to the second support member 445, the control shaft 47 is provided on the right side of the first support member 446, the control shaft 47 is connected to a clockwork spring 448 on the side facing the second positioning plate 42, and the other side of the clockwork spring 448 is connected to the second positioning plate 42;

[0043] The fixing plate 48 can move along the guide rail 44 direction through a plurality of left moving rings 443 and right moving rings 444. At the same time, the second support member 445 and the first support member 446 provided can improve the stability of the fixing plate 48 when it moves, and can also prevent the fixing plate 48 from moving easily when carrying the distributor. When the fixing plate 48 moves toward the first positioning plate 41, the control shaft 47 needs to be rotated so that the interference member 471 will not interfere with the first support member 446, allowing the fixing plate 48 to move. When pushing back the fixing plate 48, if the interference member 471 is set too deep, it will be difficult to push the fixing plate 48 back to the predetermined position. At this time, a tool can be used to pass through the through hole 447 from the outside of the first positioning plate 41 to interfere with the second support member 445 to push the fixing plate 48 back. At the same time, this can prevent the fixing plate 48 from touching the distributor when it is pushed back, thereby improving the stability and safety of the distribution network operation control system.

[0044] The movement of the fixed plate 48 toward the first positioning plate 41 stops when the left movable ring 443 and the right movable ring 444 come into contact with the first positioning plate 41. At this time, the fixed plate 48 can partially extend through the opening 43 of the first positioning plate 41, which makes it easier to install the distributor on the fixed plate 48.

[0045] When the control shaft 47 is rotated, the clockwork spring 448 provided between the control shaft 47 and the second positioning plate 42 will gradually tighten, and after the control shaft 47 is released, the clockwork spring 448 will reset, so that the contact member 471 returns to its original position, so that there is no need to manually control the rotation angle of the control shaft 47, to prevent the control shaft 47 from being at an incorrect angle due to accidental touch or vibration, so that the contact member 471 cannot contact the first support member 446, causing the position of the fixed plate 48 to move. Therefore, the clockwork spring 448 is provided to improve the stability and safety of the distribution network operation control system.

[0046] Furthermore, the fixing plate 48 is provided with a plurality of mounting holes 481 and mounting slots 482 for mounting the distributor, so as to adapt to different installation and positioning of the distributor.

[0047] Furthermore, the control shaft 47 passes through the first positioning plate 41 on the side facing the first positioning plate 41 and is fixedly connected with a knob 473 , which can facilitate the rotation of the control shaft 47 .

[0048] Furthermore, a double door 11 is installed on the front of the housing 1, a first dustproof net 12 is connected to the bottom of the double door 11, the first dustproof net 12 is fixedly connected to the housing 1, and a second dustproof net 15 corresponding to the fan 13 is installed on the back of the housing 1;

[0049] The double-door 11 can facilitate the staff to explore the situation inside the shell 1 during maintenance. When the fan 13 is used to force the air convection inside and outside the shell 1 to dissipate heat, the shell 1 can only perform internal and external air convection at the first dustproof net 12 and the fan 13. The cold air outside the shell 1 enters from the first dustproof net 12, and the hot air inside the shell 1 is discharged from the shell 1 by the fan 13. Because the dust in the air outside the shell 1 may have an adverse effect on the distributor, the first dustproof net 12 and the second dustproof net 15 are set to block the dust in the air to ensure the stability and safety of the distribution network operation control system.

[0050] Further, such as Figure 9 As shown, the resisting member 471 is in the shape of a right-angled triangular pyramid, with the longest edge of the resisting member 471 facing the first positioning plate 41 and having rounded corners. The resisting member 471 is connected to a screw 472 and is detachably connected to the control shaft 47 through the screw 472;

[0051] The resistance member 471 can be connected to different positions on the control shaft 47 using screws 472, so that the fixed position of the fixing plate 48 in the mounting frame 4 can be adjusted to adapt to the installation of different types of distributors. When the fixing plate 48 does not need to be moved, the side of the resistance member 471 facing the second positioning plate 42 can resist the side of the first support member 446 facing the first positioning plate 41, thereby limiting the fixing plate 48. When the fixing plate 48 is pushed back, the end of the first support member 446 facing the second positioning plate 42 will resist the longest edge of the right triangular pyramid. At this time, as the fixed plate 48 is pushed back, the first support member 446 can cause the resistance member 471 to rotate around the control shaft 47 by contacting the edge, and the resistance member 471 can be rotated to an angle where it does not interfere with the first support member 446. In this way, there is no need to twist the control shaft 47 again when pushing back the fixed plate 48. In addition, the longest edge is rounded to prevent damage to the first support member 446 due to interference, and the fixed plate 48 can also remain stable when pushed back, thereby ensuring the stability and safety of the distribution network operation control system.

[0052] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
