Description

Technical Field

[0001] This invention relates to the field of power distribution cabinet technology, and more specifically to a low-voltage power distribution cabinet for power plants. Background Technology

[0002] Currently, all low-voltage distribution cabinets on the market require the installation and wiring of their internal protection devices and switching equipment before operation. When supplying power to multiple electrical devices, the number of protection devices and switching devices inside the low-voltage distribution cabinet is very large, which requires technicians to spend a long time assembling, resulting in low work efficiency. Summary of the Invention

[0003] In view of this, the present invention provides a low-voltage distribution cabinet for power plants to solve the problem that the large number of internal devices in the low-voltage distribution cabinet requires technicians to spend a long time assembling them, resulting in low work efficiency.

[0004] In a first aspect, the present invention provides a low-voltage distribution cabinet for power plants. The low-voltage distribution cabinet for power plants includes:

[0005] The main body of the power distribution system includes a cabinet and a cover plate, wherein the cabinet and the cover plate form a hollow rectangular structure, and the top of the cabinet is provided with a cover plate connected by hinges.

[0006] The fixed frame is a rectangular frame structure. The outer two sides of the fixed frame and the inner wall of the cabinet form a hollow cable passage chamber for neat cable routing.

[0007] Multiple busbar assemblies are equally spaced and arranged in the top area of ​​the fixed frame. The outer sides of the busbar assemblies are used for incoming and outgoing wiring, respectively, to complete the current closed-loop operation inside the power distribution body.

[0008] Multiple assembly units are arranged at equal intervals in the middle area of ​​the fixed frame for the installation of working equipment and wiring connection.

[0009] A disassembly and assembly mechanism is provided on the assembly body; under the action of external force, the disassembly and assembly mechanism has a first position that moves away from the fixed frame to separate the assembly body from the fixed frame; and a second position that moves towards the fixed frame to connect the assembly body to the fixed frame.

[0010] Beneficial Effects: This embodiment, by setting up an assembly body and a disassembly / removal mechanism, allows for direct installation and power distribution. The corresponding assembly body is quickly installed to the fixed frame via the disassembly / removal mechanism, completing the installation process rapidly. Afterwards, cables are threaded uniformly inside the wiring compartment, quickly completing the assembly of the entire distribution cabinet. The operation is convenient and fast, resulting in higher installation efficiency. Throughout the process, workers do not need to stand for extended periods. Furthermore, the height of the assembly body can be flexibly adjusted according to the number and height of electrical components, terminal block assemblies, and measuring units, providing greater installation freedom.

[0011] Furthermore, multiple assembly units are evenly spaced inside the fixed frame. When assembling the entire distribution cabinet, electrical components, terminal block components, and measuring units can be directly installed and powered on the ground outside. Throughout the process, workers can operate while sitting on the ground, and multiple workers can simultaneously install and wire different components without having to stand in one position for a long time to install multiple electrical components, terminal block components, and measuring units. This prevents workers from experiencing discomfort during installation.

[0014] A limiting body is disposed on the fixed frame and is correspondingly disposed to the mounting body;

[0015] Under the action of external force, the mounting body moves towards the fixed frame, and after abutting against the limiting body, pushes one end of the limiting body to rotate, so that the other end of the limiting body is engaged with the mounting body;

[0016] Under the action of external force, the mounting body moves away from the fixed frame and separates from the limiting body. The limiting body then resets, causing the other end of the limiting body to separate from the mounting body.

[0017] In one optional implementation, the mounting body includes:

[0018] A connecting spring, one end of which is connected to the inner wall of the assembly body;

[0022] A limiting block is arranged on the moving column;

[0023] Under the action of an external force, the cross plate drives the moving column to move towards the fixed frame body, the connecting spring is compressed, and after the moving column abuts against the limiting main body, it pushes one end of the limiting main body to rotate, so that the other end of the limiting main body is clamped with the limiting block;

[0024] After the external force disappears, under the elastic force of the connecting spring, the cross plate drives the moving column to move away from the fixed frame body. After the moving column is separated from the limiting main body, the limiting main body resets, so that the other end of the limiting main body is separated from the limiting block.

[0025] In an optional implementation manner, the top end of the moving column is arranged in a horizontal structure up and down, and the limiting block is arranged inside the horizontal structure.

[0033] When the installation main body moves towards the fixed frame body, after the installation main body abuts against the trigger plate, it pushes the rotating cylinder to rotate, so that the limiting plate is clamped with the installation main body, and the torsion spring is compressed;

[0034] When the mounting body moves away from the fixed frame, after the mounting body separates from the trigger plate, the rotating cylinder resets under the elastic force of the torsion spring, causing the limiting plate to separate from the mounting body.

[0035] In one alternative implementation, the working device includes at least electrical components, terminal block components, and a measuring unit.

[0053] Beneficial effects: In this embodiment, the warning component can be flexibly moved on the terminal block assembly. Therefore, when external equipment is operating normally, if an operator makes a human error while operating the inside of the distribution cabinet, the warning device can serve as a warning to the operator when it is set at the switch position of the corresponding terminal block assembly, thus preventing the sudden stop and start of external equipment.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0079] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0080] The following is combined with Figures 1 to 16 The following describes embodiments of the present invention.

[0081] According to an embodiment of the present invention, a low-voltage distribution cabinet for power plants is provided, comprising a distribution body 1, which includes a cabinet body 1001 and a cover plate 1002. The cabinet body 1001 and the cover plate 1002 form a hollow rectangular structure, and the top of the cabinet body 1001 is provided with a cover plate 1002 connected by hinges. A fixing frame 3 is provided, which is arranged in a rectangular frame structure, and its outer two sides form a hollow cable passage chamber 2 between the inner wall of the cabinet body 1001 for neatly wiring cables.

[0082] The low-voltage distribution cabinet used in this power plant also includes;

[0083] Busbar assembly 4 has multiple units evenly spaced at the top of the fixed frame 3, such as 3, 4, 5, etc., and its outer sides are used for incoming lines and wire threading, respectively, to complete the current closed-loop operation inside the power distribution body 1.

[0084] The assembly body 5, which is evenly spaced in the middle of the fixed frame 3, is used for the installation of working equipment and wiring connections. The working equipment includes at least electrical components 8, terminal block components 9, and measuring units.

[0085] The assembly body 5 is externally equipped with a disassembly and assembly mechanism for quick installation with the fixed frame 3. Under external force, the disassembly and assembly mechanism has a first position where it moves away from the fixed frame 3, separating the assembly body 5 from the fixed frame 3; and a second position where it moves closer to the fixed frame 3, connecting the assembly body 5 to the fixed frame 3. In this embodiment, the external force can be manual or driven by a driving device. Of course, this embodiment is merely an example and is not intended to limit the scope. Those skilled in the art can modify it according to actual conditions to achieve the same technical effect.

[0086] This embodiment, by setting up the assembly body 5 and the disassembly and assembly mechanism, allows for direct installation and power distribution. The corresponding assembly body 5 is quickly installed to the fixed frame 3 via the disassembly and assembly mechanism, completing the installation process quickly. Afterwards, the cables are uniformly threaded inside the wiring compartment 2, quickly completing the assembly of the entire power distribution cabinet. The operation is convenient and fast, resulting in higher installation efficiency. Throughout the process, workers do not need to stand for extended periods. Furthermore, the height of the assembly body 5 can be flexibly adjusted according to the number and height of electrical components 8, terminal block components 9, and measuring units, providing greater installation freedom.

[0087] Furthermore, multiple assembly bodies 5 are evenly spaced inside the fixed frame 3. When assembling the entire distribution cabinet, electrical components 8, terminal block components 9, and measuring units can be directly installed and powered on the ground outside. Throughout the process, workers can operate while sitting on the ground, and multiple workers can simultaneously install and wire different components without having to stand in one position for a long time to install multiple electrical components 8, terminal block components 9, and measuring units. This prevents workers from experiencing discomfort during installation.

[0088] Furthermore, in an optional embodiment, the disassembly and assembly mechanism includes an installation body 6 and a limiting body 7. The installation body 6 is located on both sides of the assembly body 5 and moves back and forth on both sides of the assembly body 5 to complete the limiting and separation work with the limiting body 7.

[0089] Specifically, under the action of external force, the mounting body 6 moves towards the fixed frame 3, and after abutting against the limiting body 7, pushes one end of the limiting body 7 to rotate, so that the other end of the limiting body 7 is engaged with the mounting body 6;

[0090] Under the action of external force, the mounting body 6 moves away from the fixed frame 3 and separates from the limiting body 7. The limiting body 7 then resets, causing the other end of the limiting body 7 to separate from the mounting body 6.

[0091] Furthermore, in an alternative embodiment, the electrical component 8 includes at least a circuit breaker, a disconnector, a fuse, a contactor, and a relay, which are responsible for ensuring the safe and reliable transfer of electrical energy to various electrical devices, and the terminal block assembly 9 is used for connecting and distributing electrical energy.

[0092] This application provides a low-voltage distribution cabinet for power plants with a disassembly and assembly mechanism. Specifically, during the assembly of the distribution cabinet, the entire assembly body 5 is initially separated from the entire distribution body 1. Therefore, in the early stages, workers can sit on the assembly body 5 to install the electrical components 8, terminal block components 9, and various electrical components on the measuring unit. The specific installation method is as follows: an installation slide rail is provided on the middle inner wall of the assembly body 5. The electrical components 8, terminal block components 9, and measuring units are engaged with the installation slide rail, and then the wiring is performed. After the electrical components on the entire assembly body 5 are installed, the assembly body 5 can be properly installed on top of the fixed frame 3. During installation, it is necessary to control the engagement between the installation body 6 on the assembly body 5 and the limiting body 7 on the fixed frame 3. After engagement, the assembly work is completed. After assembly, the main lines are then wired through the wiring chamber 2, thus completing the assembly of the entire distribution cabinet. The operation is convenient.

[0093] Among them, according to Figure 3 As shown, the fixed frame 3 includes 4 fixed vertical rods 31, and the 4 fixed vertical rods 31 are arranged in a rectangular shape. Two horizontal connecting rods 33 are symmetrically installed at the front and rear positions of the top of the 4 fixed vertical rods 31, and the horizontal connecting rods 33 are welded to the fixed vertical rods 31.

[0094] Longitudinal connecting rods 32 are provided at equal intervals between two fixed vertical rods 31 that are symmetrical front and back. The interior of the longitudinal connecting rods 32 is set as a hollow structure, and a limiting body 7 is set inside the hollow structure. An assembly body 5 is set between the two longitudinal connecting rods 32 that are symmetrical left and right, and perforations 51 are evenly distributed on both sides of the assembly body 5.

[0095] Specifically, the horizontal connecting rods 33 can support the bottom of the four fixed vertical rods 31 by being arranged vertically and vertically. The equally spaced longitudinal connecting rods 32, which have a limiting body 7 inside, can be installed in correspondence with the mounting body 6 on the assembly body 5, so that the installation position of the assembly body 5 can be flexibly adjusted when it needs to be replaced.

[0096] Further, in an optional implementation manner, the installation main body 6 includes a connecting spring 63, a connecting plate 62, a cross plate 61, a moving column 64 and a limiting block 65.

[0097] One end of the connecting spring 63 is connected to the inner wall of the assembly main body 5, and the connecting plate 62 is connected to the other end of the connecting spring 63. The cross plate 61 is arranged on the connecting plate 62, the moving column 64 is arranged on the end face of the cross plate 61 close to the assembly main body 5 and extends in the direction close to the assembly main body 5, and a through hole 51 corresponding to the moving column 64 is formed in the assembly main body 5 for the moving column 64 to pass through. The limiting block 65 is arranged on the moving column 64.

[0098] During the actual installation process, under the action of an external force, the cross plate 61 drives the moving column 64 to move in the direction close to the fixed frame body 3, the connecting spring 63 is compressed, and after the moving column 64 abuts against the limiting main body 7, it pushes one end of the limiting main body 7 to rotate, so that the other end of the limiting main body 7 is clamped with the limiting block 65.

[0099] After the external force disappears, under the elastic force of the connecting spring 63, the cross plate 61 drives the moving column 64 to move in the direction away from the fixed frame body 3. After the moving column 64 is separated from the limiting main body 7, the limiting main body 7 resets, so that the other end of the limiting main body 7 is separated from the limiting block 65.

[0100] Among them, according to Figures 3 to 8 As shown, when installing through the installation main body 6 and the limiting main body 7, the installation main body 6 includes 3 cross plates 61 and 2 connecting plates 62, and the 3 cross plates 61 and 2 connecting plates 62 are arranged in a "king" - shaped structure. The top ends of the cross plates 61 are evenly distributed with moving columns 64 penetrating inside the through holes 51, and connecting springs 63 are arranged between adjacent moving columns 64 and are connected to the inner wall of the assembly main body 5.

[0101] Specifically, the top end of the moving column 64 is set to be a horizontal structure up and down, and a limiting block 65 is also arranged at the position slightly inside its top end. A reserved hole 66 penetrates through the surface of the connecting plate 62, and a bolt 67 is arranged inside the reserved hole 66 and is connected to a threaded hole on the inner wall of the assembly main body 5.

[0102] Further, in an optional implementation manner, the limiting main body 7 includes a rotating cylinder 71, a trigger plate 72 and a limiting plate 73. The trigger plate 72 and the limiting plate 73 are distributed on the outside of the rotating cylinder 71, and a torsion spring 75 is arranged in the middle circular hole of the rotating cylinder 71 and is connected to a fixed shaft rod 74. The front and rear top ends of the two sides of the fixed shaft rod 74 are connected to the front and rear top ends of the longitudinal connecting rod 32.

[0103] During actual installation, when the mounting body 6 moves toward the fixed frame 3, the mounting body 6 abuts against the trigger plate 72 and pushes the rotating cylinder 71 to rotate, so that the limiting plate 73 engages with the mounting body 6 and the torsion spring 75 is compressed.

[0104] When the mounting body 6 moves away from the fixed frame 3, after the mounting body 6 separates from the trigger plate 72, the rotating cylinder 71 resets under the elastic force of the torsion spring 75, causing the limiting plate 73 to separate from the mounting body 6.

[0105] The specific installation process is as follows:

[0106] First, two workers are needed to assist in the process. One worker lifts the entire assembly body 5, while the other worker lifts the horizontal plates 61 on both sides of the assembly body 5. This pulls the horizontal plates 61 and connecting plates 62, causing them to move towards the center of the assembly body 5 under the action of the connecting springs 63. This causes the horizontal plates 61 to move their top moving posts 64 inward, thus locking the entire "U"-shaped assembly body 5 into the middle of the two longitudinal connecting rods 32. Once in the correct position, the workers release the pull on the horizontal plates 61, allowing them to reset under the action of the connecting springs 63 and move outward. This outward movement causes the moving posts 64 to also move outward. As the moving posts 64 move outward, they are connected to the longitudinal connecting rods 32. The through hole on the surface of rod 32 leads to its internal hollow structure. When it moves, it contacts the trigger plate 72 on the limiting body 7 in its hollow structure, thereby pushing the trigger plate 72 to rotate around the rotating cylinder 71. When the rotating cylinder 71 rotates, it drives the external limiting plate 73 to rotate. When the limiting plate 73 rotates to the lowest position, its top end will engage with the gap between the limiting block 65 and the moving column 64, achieving the effect of engaging and limiting the position of the moving column 64. Thus, the initial position determination of the assembly body 5 is completed. At this time, the support personnel can loosen the support of the assembly body 5, take out the external bolt 67, and make it threadedly connected between the reserved hole 66 and the threaded hole on the inner wall of the assembly body 5, thereby completing the position fixation of the assembly body 5.

[0107] In this embodiment, when it is necessary to disassemble the assembly body 5, the bolts 67 are removed and the horizontal plate 61 is pulled inward repeatedly, so that the moving column 64 does not press the trigger plate 72. As a result, the rotating cylinder 71 is reset under the action of the torsion spring 75, and the limiting plate 73 will not limit the limiting blocks 65, thus completing the purpose of disassembly.

[0108] Furthermore, in an alternative implementation, according to Figure 10-12 As shown, the terminal block assembly 9 includes multiple terminal block bodies 91 arranged at equal intervals. A trigger switch 92 is provided on the surface of the terminal block body 91. A connecting seat 93 is provided at the bottom of the terminal block body 91, and a hollow groove 931 is provided inside the connecting seat 93. A locking component 95 is provided inside the hollow groove 931 and connected to an identification component 94. The identification component 94 is used to identify externally controlled electrical equipment.

[0109] In this embodiment, the marking component 94 is locked inside the hollow groove 931 by a locking component 95. Simultaneously, a pushing component 10 is also provided inside the hollow groove 931. When installing the marking component 94, the operator only needs to press it once to complete the installation with the locking component 95. When disassembly is required, simply press the marking component 94 again to unlock it from the locking component 95, and then push the pushing component 10 to disassemble the marking component 94. The entire disassembly and installation process is very quick, allowing for flexible adjustments when changing wiring. This prevents clutter, ensures clear markings for easy reference by subsequent operators, and makes the environment inside the distribution cabinet more streamlined.

[0110] Furthermore, in an optional embodiment, a pushing component 10 is also provided in the hollow groove 931 inside the connector 93 for pushing out the unlocked identification component 94.

[0111] Specifically, the pushing assembly 10 includes a push plate 101 and a return spring 102. The back of the push plate 101 is provided with a return spring 102 connected to the inner wall of the hollow groove 931.

[0112] The signage component 94 includes a sign plate 941, a mounting block 942, and a connecting block 943. The mounting block 942 is integrally mounted on the back of the sign plate 941, and the connecting block 943 is provided on the outer side of the mounting block 942. The position of the connecting block 943 corresponds to the position of the locking component 95, and the inner side of the connecting block 943 is arranged in an arc shape.

[0113] like Figure 11 and Figure 12 As shown, the locking assembly 95 is disposed in the rectangular holes on the inner side of both sides of the hollow groove 931. A fixing rod 951 is fixed in the middle of the rectangular hole, and a fixing seat 952 is disposed on the inner side of the outer side of the fixing rod 951, and a movable seat 953 is disposed on the outer side. The movable seat 953 and the fixing seat 952 are connected by an intermediate spring 954.

[0114] Furthermore, in an optional embodiment, a first locking block 955 is integrally installed on the top of the fixed base 952, and the top of the first locking block 955 is set with an arc-shaped structure both inside and outside. A second locking block 956 is integrally installed on the top of the movable base 953, and the outer top of the second locking block 956 is set with a rectangular structure.

[0115] Specifically, firstly, when installing the sign component 94, the sign component 94 needs to be removed so that it engages with the hollow groove 931 inside the connecting seat 93. When the sign component 94 engages, the mounting block 942 on the back of the sign plate 941 will drive the connecting block 943 to move inside the hollow groove 931. When it moves to the inner position, it will engage with the first locking block 955. The arc-shaped cross-sections of the two engage with each other, which will cause the connecting block 943 to engage between the first locking block 955 and the second locking block 956. Thus, by limiting the position of the connecting block 943, the position installation of the entire sign plate 941 is completed.

[0116] When disassembly is required, the label plate 941 can be pressed down to make the connecting block 943 continue to be squeezed between the second locking block 956 and reach the inside of the second locking block 956. At this time, since the hollow groove 931 is equipped with a pushing component 10, it will push the entire mounting block 942, thereby completely pushing the entire label component 94 out of the hollow groove 931 and completing the disassembly work.

[0117] In this embodiment, since the movable seat 953 can move outside the fixed rod 951, when the connecting block 943 fully reaches the inner side of the second locking block 956, in conjunction with the pushing operation of the pushing component 10, the second locking block 956 and the movable seat 953 will be pushed together to the position of the first locking block 955, and then completely pushed out.

[0118] The pushing action of the pushing component 10 is that after the marking component 94 is installed, it squeezes the reset spring 102. When it is squeezed and disassembled again, it will squeeze the reset spring 102 again. Thus, when the entire marking component 94 is not restricted by any force, the reset spring 102 resets and drives the push plate 101 to push the entire marking component 94 out completely.

[0119] Furthermore, in an optional embodiment, a slide rail assembly 12 is provided on the upper part of the terminal block body 91 and the bottom of the connector 93. The slide rail assembly 12 includes a concave slide rail 122 and an arc-shaped limiting groove 121. The arc-shaped limiting groove 121 is provided on the outer wall of the concave slide rail 122.

[0120] Furthermore, in an optional embodiment, a warning component 11 is provided on the outside of the slide rail assembly 12 for providing operational warnings. The vertical position of the warning component 11 engages with the slide rail assembly 12 located above the terminal block body 91 and at the bottom of the connector 93.

[0121] In this embodiment, the warning component 11 can be flexibly moved on the terminal block component 9. Therefore, when the external equipment is operating normally, if the operator makes a human error while operating the inside of the power distribution cabinet, the warning device can serve as a warning to the operator when it is set at the corresponding switch position of the terminal block component 9, thus preventing the external equipment from stopping or starting suddenly.

[0122] Furthermore, in an optional implementation, the warning component 11 includes a warning body 111 and a limiting component 112 located on the warning body 111.

[0123] Specifically, the limiting component 112 includes a pressing block 1121, a connecting rod 1123, a compression spring 1122, and a protruding spring piece 1124. The bottom of the pressing block 1121 is integrally mounted with the connecting rod 1123, and the outside of the connecting rod 1123 is provided with a compression spring 1122 that connects to a through groove on the inner wall of the warning body 111. The lower part of the outer wall of the connecting rod 1123 is connected to the protruding spring piece 1124.

[0124] The warning body 111 is provided with a locking hole corresponding to the position of the protruding spring piece 1124, which is used for the protruding spring piece 1124 to pass through and engage with the arc-shaped limiting groove 121.

[0125] When the external equipment corresponding to the terminal block is in manual operation, to avoid human error inside the distribution cabinet, the operator can press the pressing block 1121, causing it to drive the connecting rod 1123 to press the compression spring 1122. This causes the connecting rod 1123 to retract its external protruding spring piece 1124 into the warning body 111, thus separating the protruding spring piece 1124 from the arc-shaped limiting groove 121. This allows the warning body 111 to slide on the concave slide rail 122. When it slides to the appropriate switch position of the terminal block assembly 9, the pressure on the pressing block 1121 is released, causing the compression spring 1122 to reset. This causes the connecting rod 1123 to rise, which in turn causes the protruding spring piece 1124 to extend out of the engaging hole and engage with the arc-shaped limiting groove 121, completing the position fixation work and ensuring that no position displacement occurs.
