Description

Technical Field

[0001] The present invention relates to the technical field of switch cabinets, and in particular to a 10kV efficient, reliable and intelligent switch cabinet. Background Art

[0002] In the field of power distribution, 10kV switchgear is a core equipment. Its safety and ease of operation directly affect the efficiency of power grid operation. Traditional switchgear has the following technical bottlenecks:

[0003] Limited operating space for terminal blocks: Existing terminal blocks are mostly arranged in a fixed manner, making it difficult for operators to observe and operate during dense wiring. This is especially true during on-site modification or maintenance, as the narrow space can easily lead to miswiring or the risk of electric shock.

[0004] Lack of precise monitoring during the trolley pushing process: The contact process of the moving and static contacts of the trolley-type switchgear relies on manual visual judgment, which can easily lead to poor contact due to inadequate pushing, or damage the equipment due to excessive pushing, and there is a lack of double protection mechanism.

[0005] Single safety warning method: Traditional switch cabinets only use mechanical limit or simple indicator lights to indicate the position of the trolley. The warning effect is insufficient under complex working conditions, and there is a risk of misoperation.

[0006] Low space utilization in the cable room: The terminal blocks in the cable room are fixedly installed and cannot be adjusted according to the cable specifications, resulting in confusing wiring and poor heat dissipation performance.

[0007] To solve the above problems, this application proposes a 10kV efficient and reliable intelligent switchgear, which optimizes the operating space, precisely controls the process and improves safety performance through a stepped terminal rack, a dual-criteria monitoring system and a multi-level warning device. Summary of the Invention

[0008] The purpose of the present invention is to solve the following technical bottlenecks in the switch cabinets in the prior art: Limited operating space for wiring terminals: Existing wiring terminals are mostly arranged in a fixed manner, which makes it difficult for operators to observe and operate during dense wiring. Especially during on-site modification or maintenance, the narrow space can easily lead to miswiring or electric shock risks. Lack of precise monitoring of the trolley pushing process: The contact process of the moving and static contacts of the trolley-type switch cabinet relies on manual visual judgment, which can easily lead to poor contact due to inadequate pushing, or damage to the equipment due to excessive pushing, and lacks a double protection mechanism. Single safety warning means: Traditional switch cabinets only use mechanical limits or simple indicator lights to indicate the position of the trolley. The warning effect is insufficient under complex working conditions, and there is a risk of misoperation. Low space utilization in the cable room: The wiring terminals in the cable room are fixedly installed, and the angle cannot be adjusted according to the cable specifications, resulting in chaotic wiring and poor heat dissipation performance.

[0009] In order to overcome the shortcomings of the above, a 10kV efficient and reliable intelligent switchgear was proposed.

[0010] In order to achieve the above object, the present invention adopts the following technical solutions:

[0011] The 10kV efficient and reliable intelligent switchgear includes a switchgear cabinet body, wherein the switchgear cabinet body is provided with an instrument room, a trolley room, and a cable room. A frame is provided inside the trolley room, and a trolley panel is slidably connected to the top of the frame. A monitoring component and two sets of reminder components are provided inside the frame. The monitoring component is used to monitor the movement distance of the trolley panel, and the reminder component is used to remind the user of the movement distance of the trolley panel.

[0012] A fixed inclined plate is fixedly connected to the interior of the cable chamber, a plurality of rectangular through holes are opened in the fixed inclined plate, a mounting bracket is connected to the interior of the rectangular through holes via a connecting component, a plurality of elliptical holes are opened in the mounting bracket, and a terminal is fixedly connected to one side of the mounting bracket;

[0013] Among them, by operating the connection component, the mounting frame can be rotated to increase the operating space of the terminal block; the monitoring component monitors the position of the trolley panel and provides warnings through the reminder component.

[0015] In one possible design, the monitoring component also includes two grooves opened on the inner wall of one side of the frame, and the same U-shaped plate is slidably connected inside the two grooves. Two compression springs are arranged between one side of the U-shaped plate and the inner wall of one side of the frame, and a clearance hole is opened in the middle of the U-shaped plate; wherein, when the sliding block moves excessively and conflicts with the U-shaped plate, the compression spring is compressed to generate resistance.

[0016] In one possible design, the reminder component includes a rotating shaft rotatably connected to the inner wall of the frame, a gear is fixedly sleeved on the outer wall of the rotating shaft, a rack is slidably connected to the inner wall of the bottom of the frame, the rack is engaged with the gear, one end of the rack is fixedly connected to a side plate, and push plates are fixedly connected on both sides of the sliding block, and the push plates are used in conjunction with the side plates; wherein, when the sliding block moves, it pushes the rack to drive the gear to rotate.

[0017] In one possible design, a plurality of shading baffles are fixedly connected to the outer wall of the rotating shaft, and the plurality of shading baffles are arranged in a ring shape. LED lights are fixedly installed between the shading baffles. Two rectangular holes are opened on one side of the frame, and transparent windows are fixedly installed inside the rectangular holes. A protective box is fixedly installed on the inner wall of one side of the frame; wherein, the light of the LED lamp is displayed through the transparent window.

[0018] In one possible design, the connecting component includes four circular grooves opened on the inner wall of the rectangular through hole, and the four circular grooves are symmetrically arranged on the inner walls on both sides of the rectangular through hole. A sliding circular plate is slidably connected inside the circular groove, and one end of the sliding circular plate is rotatably connected to a threaded rod, and one end of the threaded rod is threaded through the circular groove and fixedly installed with an adjustment block.

[0019] In a possible design, an annular groove is provided on one side of the sliding circular plate, and two arc-shaped sliders are rotatably connected inside the annular groove. One side of the two arc-shaped sliders is fixedly connected to the same rotating circular plate, and two limiting arc blocks are fixedly installed on one side of the rotating circular plate. A torsion spring is provided between one side of the rotating circular plate and one side of the sliding circular plate, and two strip blocks are fixedly connected to one side of the mounting frame, and one side of the strip block is fixedly connected to a round rod; wherein, the rotating adjustment block drives the threaded rod to move, so that the limiting arc block disengages from the round rod.

[0020] In a possible design, two handles are fixedly connected to one side of the frame, and moving wheels are rotatably connected to both sides of the frame.

[0021] In a possible design, it also includes a lightning arrester and a contact arm, the lightning arrester is fixedly installed on one side of the trolley panel, one end of the contact arm is fixedly connected to the lightning arrester, and the other end is provided with a plum blossom contact; wherein, the plum blossom contact is in contact when the trolley panel moves, a plurality of voltage transformers are fixedly installed on the top of the trolley panel, and a connecting copper bus is fixedly installed on the top of the voltage transformer, and the connecting copper bus is connected to the protective cover outside the contact arm, and then is conductive with the contact arm.

[0022] In this application, the present application adopts a flip-type terminal rack, which arranges several terminal blocks in a stepped manner with the front lower and the back higher. By rotating the adjacent terminal blocks downward or upward, the wiring space can be more than doubled, which is convenient for operation and observation, improves the wiring efficiency of the terminal blocks, reduces working hours, and can effectively solve the problem of on-site modification, which is suitable for wide promotion and use;

[0023] During the specific operation, the two relative adjusting blocks are rotated, the adjusting blocks drive the threaded rod to move horizontally, the threaded rod drives the sliding circular plate to move horizontally, the sliding circular plate drives the rotating circular plate to move horizontally, and the rotating circular plate drives the limit arc block to move horizontally. At this time, the four limit arc blocks on the same side no longer clamp the corresponding round rods. If the wiring terminal needs to be rotated upward, the braking state of the lower round rod can be released. If the wiring terminal needs to be rotated downward, the braking state of the upper round rod can be released.

[0024] At this time, the terminal block can be rotated, and the terminal block drives the mounting frame to rotate, and the mounting frame rotates around the round rod whose brake is not released, and the mounting frame drives the round rod and the strip block to rotate, and the round rod and the strip block drive the limit arc block to rotate, and the limit arc block drives the rotating circular plate to rotate, and the rotating circular plate drives the arc slider to rotate inside the annular slide groove and twist the torsion spring, which can greatly increase the working space;

[0025] And when the frame is pushed into the interior of the trolley room, it can be moved normally by the moving wheel. After it is sent in, the cabinet door on one side of the trolley room is closed. At this time, the operating handle is inserted into the interior of the socket and engaged with one end of the adjusting screw rod. At this time, the operating handle can be used to drive the adjusting screw rod to rotate, and the adjusting screw rod drives the sliding block to move horizontally. The sliding block drives the upper trolley panel to move horizontally, thereby realizing the contact process of the dynamic and static contacts;

[0026] And when the sliding block moves, the travel switch on the frame can be used as the first criterion for judging the position of the trolley, and the proximity switch can be used as the second criterion for judging the position of the trolley. If the sliding block moves excessively, it will conflict with the U-shaped plate, and the U-shaped plate will squeeze the compression spring and enter the inside of the groove. At this time, the U-shaped plate will produce great resistance to the sliding block, which can be used to remind the user;

[0027] And when the sliding block moves, it will drive the pushing plate to move horizontally, the pushing plate will drive the side plate to move horizontally, the side plate will drive the rack to move, the rack will drive the gear to rotate, the gear will drive the rotating shaft to rotate, and the rotating shaft will drive multiple LED lights to rotate. Then, as the sliding block gradually goes deeper, different lights of multiple LED lights will be illuminated through the protective box, which can remind the user again.

[0028] Beneficial effects:

[0029] Through the stepped arrangement with low front and high back and the rotation adjustment mechanism, the terminal blocks can be rotated and expanded in one direction, more than doubling the operating space, solving the observation and operation difficulties during dense wiring and reducing wiring man-hours.

[0030] The independent brake release design (adjustment block controls the upper and lower round rods) allows single-row terminals to rotate independently, adapting to complex on-site modification requirements and avoiding the risk of overall disassembly.

[0031] The combination of a travel switch (metal plate and proximity switch) and a mechanical limiter (U-shaped plate and compression spring) allows for dual determination of the trolley's position. When the slider moves excessively, the U-shaped plate is compressed, triggering resistance feedback to prevent damage to the moving and static contacts.

[0032] The screw transmission mechanism (adjusting screw and sliding block) cooperates with the operating handle to ensure that the advancement process is smooth and controllable, and the contact resistance stability is improved.

[0033] The rack and pinion linkage mechanism (gear and rack) converts the trolley displacement into a rotating LED light warning, and intuitively displays the propulsion status through a transparent window, forming a visual feedback closed loop.

[0034] The shading baffle and protective box design prevent light interference, and the different colors of the LED light can be programmed to distinguish between normal and warning states.

[0035] The terminal blocks are connected to the fixed inclined plate through the mounting bracket. The rectangular through-holes allow the terminal angle to be adjusted to accommodate different cable bending radii and improve heat dissipation performance.

[0036] The oval hole design is compatible with a variety of screw specifications, improving on-site installation flexibility and reducing the number of spare parts. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0048] In one embodiment; refer to Figure 1-9The switch cabinet includes: a switch cabinet body 1 welded from cold-rolled steel plates, the interior of which is divided into an instrument room 5, a trolley room 2, and a cable room 3 by partitions. A guide rail is provided at the bottom of the trolley room 2, and four sets of moving wheels 29 with a diameter of 100 mm are installed at the bottom of the frame 30. The wheels are made of polyurethane rubber with anti-slip texture on the surface. Two handles 31 are fixedly connected to one side of the frame 30. A strip-shaped sliding hole with a width of 30 mm is provided on the top of the frame 30. The sliding block 32 is processed from 45# steel and hard chrome-plated on the surface. It cooperates with the adjusting screw rod 33 through a trapezoidal thread. Push plates 42 are fixedly connected to both sides of the sliding block 32. The screw rod pitch is 4 mm, driving the trolley panel 26 to advance at a rate of 4 mm per rotation. Three zinc oxide lightning arresters 25 of model HY5WS-17 / 50 are installed on the front of the trolley panel 26. The lightning arrester 25 is connected to the contact arm 24 through M8 stainless steel screws. The contact arm 24 is made of T2 copper tube. The front plum blossom contact 23 uses 6 beryllium bronze contact fingers with a contact pressure of 120±10N. Multiple voltage transformers 28 are fixedly installed on the top of the trolley panel 26. A connecting copper bus 27 is fixedly installed on the top of the voltage transformer 28. The connecting copper bus 27 is connected to the protective cover outside the contact arm 24, and then conducts with the contact arm 24.

[0049] The monitoring assembly also includes two grooves 36 defined on the inner wall of one side of the vehicle frame 30. The proximity switch 34, an Omron model E2E-X10ME1, has a detection distance of 10 mm and maintains a standard 5 mm spacing from the metal plate 46. A U-shaped plate 35, made of spring steel, slides within the groove 36. Compression springs 37 on either side measure Φ8 x 30 mm and have a spring constant of 2.5 N / mm. A 20 mm diameter clearance hole 38 ensures the smooth passage of the adjustment screw 33. When the sliding block 32 is excessively displaced, the U-shaped plate 35 compresses the spring 37, generating a 20 N resistance when the travel reaches 8 mm, triggering a noticeable change in resistance perceived by the operator.

[0050] The rotating shaft 48 of the reminder component is fixed to the side wall of the frame 30 through two 6002ZZ bearings. The gear 39 has a module of 1.5 and 40 teeth, and meshes with the rack 45 with a module of 1.5 and 20 teeth. One end of the rack 45 is fixedly connected to the side panel 47. Four groups of light shielding baffles 43 are evenly installed on the rotating shaft 48. Each group consists of three 1mm thick ABS plastic plates distributed at 120°, and the spacing between adjacent groups is 15mm. The LED lamp 49 uses 5050 SMD lamp beads with an operating voltage of 12V and is powered by a 12V / 5Ah lead-acid battery in the frame 30. The protective box 44 is made of PC transparent acrylic with a wall thickness of 3mm and a silk-screen scale mark on the surface. It is connected to the rectangular hole 40 through a silicone sealing strip. A transparent window 41 is fixedly installed inside the rectangular hole 40.

[0051] The present application can be used in the field of switch cabinets, and can also be used in other fields applicable to the present application.

[0052] In another embodiment; Figure 1-9 This 10kV, highly efficient and reliable intelligent switchgear is used in the switchgear field. The fixed inclined plate 8 of the cable chamber 3 is inclined at a 15° angle to the horizontal plane. The rectangular through-hole 9 measures 80mm x 40mm, with four M12 circular grooves 14 at the four corners. The threaded rod 20 of the connecting component is an M10 x 1.5 stainless steel screw. The adjustment block 6 has a knurled surface and a diameter of 35mm. The sliding circular plate 21 has an outer diameter of 22mm and an annular groove 18 on one side. Two arc-shaped sliders 17 made of polytetrafluoroethylene are embedded in the annular groove 18. A torsion spring 22 with a torque of 0.8N·m is installed between the rotating circular plate 16 and the sliding circular plate 21. The mounting frame 7 is formed by bending a 2mm aluminum alloy plate. The oval hole 11 has a long axis of 25mm and a short axis of 15mm. The terminal 10 uses the Phoenix UKK-5N model with a rated current of 63A and is fixed by M5 screws. Two strip blocks 12 are fixedly connected to one side of the mounting frame 7, and a round rod 13 is fixedly connected to one side of the strip block 12.

[0053] During operation, the operator first rotates the adjustment block 6 using a special tool, causing the threaded rod 20 to move 8mm laterally, freeing the limit arc block 15 from the constraint of the round rod 13. The single-row terminal block 10 can rotate ±45° around the round rod 13 without releasing the brake, and the spacing between adjacent rows is arranged in a stepped manner. During the trolley's advancement, the operator inserts a standard tool into the Φ20mm socket 4 and rotates the adjustment screw 33 to move the sliding block 32. When the metal plate 46 enters the detection range of the proximity switch 34, the green LED lights up; when the U-shaped plate 35 continues to advance and contacts the side wall of the frame 30, the yellow LED flashes as a warning; if the trolley is over-advanced, the red LED stays on and the spring resistance suddenly changes. The entire system uses dual-criteria monitoring and a three-level warning mechanism to ensure that the contact resistance of the trolley contacts is ≤30μΩ, the wiring operation space is increased by 120%, and the terminal block temperature rise is reduced to ≤15K.

[0054] However, as is well known to those skilled in the art, the working principles and wiring methods of the voltage transformer 28, proximity switch 34 and LED light 49 are commonplace, and are all conventional means or common knowledge, so they will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0055] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
