Technical Field

[0001] The invention relates to the technical field of control cabinets, in particular to a high-voltage solid-state soft-start control cabinet which is easy to maintain. Background Art

[0002] High voltage solid state soft starter is a new type of medium and high voltage motor soft starter, mainly suitable for medium and high voltage AC motors below 10KV, using advanced DSP control technology, power electronics technology and its main components are three-phase phase-parallel thyristor and its electronic control circuit connected in series between the power supply and the controlled motor. Different functions can be achieved by using different methods to control the conduction angle of the three-phase phase-parallel thyristor so that the input voltage of the controlled motor changes according to different requirements.

[0003] The high-voltage solid-state soft start control cabinet is an integrated control cabinet for installing high-voltage solid-state soft starters. However, due to the close stacking of equipment in the cabinet, the space allowed for maintenance is narrow, especially for equipment facing away from the export side, which increases the difficulty of maintenance and is not conducive to the daily maintenance of the control cabinet. Summary of the invention

[0004] The present invention aims at solving the problems in the prior art and provides a high-voltage solid-state soft start control cabinet that is easy to maintain. The specific technical solution is as follows:

[0005] A high-voltage solid-state soft start control cabinet that is easy to maintain includes a cabinet body, one end of which is open, and further includes:

[0006] Partitions are arranged horizontally in the cabinet;

[0007] A fixed shaft is mounted on the open end of the cabinet, and the partition is rotatably connected to the fixed shaft;

[0008] and a notch formed on one side end of the cabinet to allow the partition to pass through;

[0009] The partition is driven by an external force to rotate toward the opening direction of the cabinet.

[0010] As a further technical solution of the present invention, the partition allows at least a degree of rotation.

[0011] As a further technical solution of the present invention, the partitions are provided in a plurality of groups, which are arranged in the cabinet at intervals along the vertical direction and divide the internal space of the cabinet into a plurality of accommodating spaces.

[0012] As a further technical solution of the present invention, the notch extends in the vertical direction until it covers the accommodating space.

[0013] As a further technical solution of the present invention, a rib is formed correspondingly below the notch, and the free end of the partition extends toward the notch and overlaps the rib in a normal state.

[0014] As a further technical solution of the present invention, a slideway 1 is provided at the bottom of the partition, and a slider 1 is slidably connected in the slideway 1;

[0015] A second slideway is provided on the inner side of the rib, and a second slider is slidably connected in the second slideway;

[0016] A connecting rod is rotatably connected between the slider 1 and the slider 2.

[0017] As a further technical solution of the present invention, after the partition is rotated out, the connecting rod drives the slider 1 to slide on the slideway 1 to the diagonal position of the fixed axis in the partition.

[0018] As a further technical solution of the present invention, a baffle is connected to the side where the partition is overlapped to the rib, and the baffle is rotatably set on the partition and has at least a vertical state and a horizontal state. In the vertical state, the baffle can cooperate with the partition to fill the gap to make the side end of the cabinet flat, and in the horizontal state, the space above the partition can be completely exposed.

[0019] The beneficial effects of the present invention are as follows:

[0020] (1) In the present application, by setting a fixed axis and a notch, the partition connected to the electronic components above it can be directly rotated out toward the open end of the cabinet, which provides a better inspection field and is more conducive to inspection and maintenance; and the partition can be rotated out at least degrees when it is rotated out, so that the original back of the partition can be rotated to the side, eliminating blind spots for inspection.

[0021] (2) In the present application, a connecting rod is also provided, which can be hidden in the space at the bottom of the partition under normal conditions, and can at least partially support the bottom of the partition when the partition is rotated out, thereby ensuring the stability of the partition after it is rotated out. After the partition is rotated out, the fixed axis serves as a supporting vertex for supporting the partition, and the slider serves as another supporting vertex. The two are diagonally located in the partition, and can form a longest supporting edge, thereby improving the supporting effect on the partition. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0030] Figure 1 The overall structural diagram of a high-voltage solid-state soft-start control cabinet that is easy to maintain is shown; Figure 1 The high-voltage solid-state soft start control cabinet that is easy to maintain includes a cabinet 100, one end of which is open for loading or removing electronic equipment; a plurality of groups of partitions 110, which are arranged in the cabinet 100 at intervals along the vertical direction and divide the internal space of the cabinet 100 into a plurality of accommodating spaces 120; a fixed shaft 130, which is installed at the open end of the cabinet 100, and the partition 110 is rotatably connected to the fixed shaft 130.

[0031] The cabinet 100 is placed vertically and has a vertical space inside; it has an open end, a closed end facing away from the open end, and two side ends opposite to each other and adjacent to the open end and the closed end. That is to say, the cross-section of the cabinet 100 is a U-shaped structure, and electronic equipment can be loaded or taken out from the open end. In actual use, a sealing component that can open or close the opening can also be installed on the open end to ensure the sealing of the cabinet 100.

[0032] The partition 110 is horizontally arranged in the cabinet 100 for carrying electronic components. In actual use, the electronic components can be directly or indirectly installed on the surface of the cabinet 100 to maintain the stability of the electronic components during operation. The accommodating space 120 is cooperatively arranged on the partition 110 for accommodating the electronic components installed on the partition 110. In actual use, the electronic components can be divided into several independent modules and installed in different accommodating spaces 120 for daily maintenance.

[0033] The fixed shaft 130 is the rotation center of the partition 110 and can be used to support the partition 110. That is, relative movement on the vertical plane is not allowed between the partition 110 and the fixed shaft 130. For example, the partition 110 and the fixed shaft 130 are connected by a bearing.

[0034] Figure 2 The schematic diagram of the structure of the partition 110 in the high-voltage solid-state soft start control cabinet after it is rotated out is shown; a notch 140 is provided on one side end of the cabinet 100 to allow the partition 110 to be rotated out, and the partition 110 is rotated out in the opening direction of the cabinet 100 driven by an external force; the notch 140 is provided to provide space for the partition 110 to be rotated out, thereby avoiding interference between the partition 110 and the cabinet 100 when the partition 110 is rotated out, which is conducive to the maintenance of the electronic components installed on the partition 110; the partition 110 is allowed to rotate at least 90 degrees; that is, the partition 110 can be rotated at least 90 degrees when it is rotated out, so that the original back side becomes the side, which is more conducive to inspection and maintenance, and because the rotation center of the partition 110 is close to the opening end of the cabinet 100, the partition 110 can be rotated out as a whole when it is rotated out 90 degrees, and the inspection field is better; the notch 140 extends in the vertical direction until it covers Cover the accommodating space 120; because when the partition 110 is rotated out, the electronic components installed above it will also rotate synchronously, and the electronic components are accommodated in the accommodating space 120. When the gap 140 expands until it covers the accommodating space 120, the electronic components can be rotated out synchronously with the partition 110 without interfering with the cabinet 100; a rib 150 is formed correspondingly below the gap 140, and the free end of the partition 110 extends toward the gap 140 and overlaps the rib 150 under normal circumstances; the rib 150 is adjacent to the bottom of the gap 140, and the partition 110 is normally overlapped on the rib 150 to form a supporting edge, and cooperates with the support of the fixed shaft 130 on the other side to form a supporting surface covering the partition 110. In other words, the rib 150 and the fixed shaft 130 are distributed on two opposite side ends of the partition 110 to ensure the stability of the partition 110 in the vertical direction under normal circumstances.

[0035] Figure 3 A schematic diagram of the structure of a slideway 111 and a slider 112 is shown; Figure 4 A schematic diagram showing the structure of the connecting rod 160 when the partition 110 is rotated out; Figure 3 and Figure 4In the embodiment, a slideway 111 is provided at the bottom of the partition 110, and a slider 112 is slidably connected in the slideway 111; a slideway 2 151 is provided on the inner side of the rib 150, and a slider 152 is slidably connected in the slideway 2 151; a connecting rod 160 is rotatably connected between the slider 112 and the slider 152; under normal conditions, the connecting rod 160 is hidden in the bottom space of the partition 110, and when the partition 110 is rotated out, the connecting rod 160 is pulled to drive the slider 112 to slide in the slideway 111, and synchronously pulls the slider 152 to slide in the slideway 2 151, that is, the connecting rod 160 is used as a supporting component connected between the rib 150 and the partition 110, and can be used in the partition 1 When the partition 110 is rotated out, the partition 110 is supported from the bottom to ensure the stability of the partition 110 after it is rotated out; after the partition 110 is rotated out, the connecting rod 160 drives the slider 112 to slide on the slide 111 to the diagonal position of the fixed axis 130 in the partition 110; that is, after the partition 110 is rotated out, the fixed axis 130 serves as a supporting vertex for supporting the partition 110, and the slider 112 serves as another supporting vertex, and at the same time, the two are diagonally located in the partition 110, thereby forming a longest supporting edge, thereby improving the supporting effect on the partition 110; in some other embodiments, the connecting rod 160 can also be a telescopic structure to adapt to the rotation angle of the partition 110 in real time.

[0036] Figure 5 shows a schematic structural diagram of the baffle 113 in a vertical state; Figure 6 A structural schematic diagram of the baffle 113 in a horizontal state is shown; the baffle 113 is connected to the side where the partition 110 is overlapped to the rib 150, and the baffle 113 is rotatably set on the partition 110 and has at least a vertical state and a horizontal state. In the vertical state, the baffle 113 can cooperate with the partition 110 to fill the gap 140 to make the side end of the cabinet 100 flat, and in the horizontal state, the baffle 113 can make the space above the partition 110 completely exposed; under normal conditions, the baffle 113 can maintain a vertical state, so that it can cooperate with the partition 110 to completely block the gap 140, ensuring that the cabinet 100 can be completely sealed under normal conditions, and after the partition 110 is rotated out, the baffle 113 can be expanded outward until it is horizontal, which can not only make the space above the partition 110 completely exposed, but also form a support platform for placing maintenance items, which is convenient for maintenance personnel to take.

[0037] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
