Description

Technical Field

[0001] This utility model relates to the field of ring main unit technology, and more specifically, to a ring main unit with a rotating quick-installation panel system in the mechanism room. Background Technology

[0002] A ring main unit is an electrical device that houses a group of power transmission and distribution equipment (high-voltage switchgear) in a metal or non-metal insulated cabinet or is assembled into a modular ring main unit. Its core components are load switches and fuses. It has advantages such as simple structure, small size, low price, improved power supply parameters and performance, and enhanced power supply safety.

[0003] However, the current ring main unit has the following problems: 1. Since most of the components on the panel of the ring main unit are connected to the interior through secondary wires, these secondary connection wires must be disconnected before disassembling the panel. After maintenance, when reinstalling the panel, these secondary wires need to be reconnected, which can easily lead to wiring errors and increase workload and risk. 2. When it is necessary to inspect the indoor components or the components on the back of the panel, the maintenance personnel must use tools to unscrew all the fixing screws one by one in order to remove the entire panel. This process involves many steps and takes a long time, which is inefficient, especially in situations where space is limited or frequent inspections are required.

[0004] 3. The left and right side panels of the mechanism room frame of traditional ring main unit are usually designed as flat plate structures. The sealing between the panel and the frame is mainly achieved by sealing strips and screws. This structure has relatively limited protection at the joint between the panel edge and the frame, and there is limited room for improvement in the protection level against the intrusion of dust, moisture, small insects, etc. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a ring main unit with a rotating quick-install panel system in the mechanism room, which aims to solve the problems mentioned in the background art.

[0006] To solve the above problems, the present invention adopts the following technical solution: A ring main unit with a rotating quick-install panel system for the mechanism room includes: Cable room; The air chamber is located above the cable chamber; The mechanism room is located above the cable room, and a mechanism room panel is provided on one side of the mechanism room; The control room is located above the mechanism room; Also includes: A sealing mechanism, disposed on the mechanism chamber, for the purpose of sealing; and Multiple sets of connection mechanisms are provided, all located on the mechanism chamber, and are used to connect the mechanism chamber and the mechanism chamber panel.

[0007] As a preferred embodiment of this utility model, the mechanism chamber is composed of multiple mechanism chamber side plates, mechanism chamber top plates, and mechanism chamber bottom plates.

[0008] As a preferred embodiment of the present invention, the sealing mechanism includes a plurality of sealing strips, which are respectively installed on the outer wall of one side of the mechanism chamber side plate, the mechanism chamber top plate, and the mechanism chamber bottom plate.

[0009] As a preferred embodiment of this utility model, the connecting mechanism includes a fixed seat, which is fixedly installed on the outer wall of the mechanism chamber. A rotating shaft is rotatably embedded in the outer wall of the fixed seat. An upper rotating hinge and a lower rotating hinge are sleeved on the outer surface of the rotating shaft. The upper rotating hinge, the lower rotating hinge, and the mechanism chamber panel are all fixedly connected. A connecting shaft is embedded between the upper rotating hinge and the lower rotating hinge. Two connecting copper sleeves are sleeved on the outer surface of the rotating shaft.

[0010] As a preferred embodiment of this utility model, each of the upper and lower rotating hinges has a plurality of mounting screws on its outer wall.

[0011] As a preferred embodiment of this utility model, a control box panel is installed on one outer wall of the control box compartment.

[0012] As a preferred embodiment of this utility model, a cable compartment door is installed on one side of the outer wall of the cable compartment. Beneficial effects

[0013] Compared with existing technologies, this utility model provides a ring main unit with a rotating quick-install panel system in the mechanism room, which has the following advantages: 1. In this solution, the cable compartment, air box compartment, mechanism compartment, and control box compartment constitute a complete ring main unit. The sealing mechanism improves the sealing effect of the mechanism compartment, which can effectively block dust, water droplets, small solid foreign objects, etc. from entering in a straight direction, thereby improving the performance of the ring main unit mechanism compartment. The connection mechanism facilitates the connection and separation of the mechanism compartment and the mechanism compartment panel, while expanding the opening angle of the mechanism compartment panel from the traditional 130° to 180°, making it convenient for maintenance personnel to carry out maintenance.

[0014] 2. In this solution, the opening angle of the mechanism room panel is extended from the traditional 130° to 180° through the connection mechanism, which maximizes the operating space of the mechanism room. Wiring personnel can access the terminal blocks and cables inside the mechanism room without obstacles, avoiding the difficulty of tool operation or blind spots caused by limited angle, and greatly reducing the risk of misconnection and omission. It is especially suitable for dense wiring scenarios.

[0015] 3. In this solution, after the side panels, top panel, and bottom panel of the mechanism room are assembled, a water guide channel is formed around the perimeter, including horizontal and vertical water guide channels. Through the seamless connection of the water guide channels in all directions, combined with the sealing mechanism, the water seepage risk caused by the splicing gaps is completely eliminated, improving the overall protection level of the mechanism room. It is suitable for harsh environments such as high humidity and dust.

[0016] 4. In this solution, the upper and lower rotating hinges are installed and fixed by mounting screws. The screw heads of each mounting screw are knurled, which makes it easy to tighten or remove manually without the need for special tools. Attached Figure Description

[0020] Example

[0021] Please see Figure 1-10 A ring main unit with a rotating quick-install panel system for the mechanism compartment comprises a cable compartment 1, an air chamber compartment 2, a mechanism compartment 3, a control box compartment 4, a sealing mechanism 9, and a connecting mechanism 8. The air chamber compartment 2 is mounted on the cable compartment 1, the mechanism compartment 3 is mounted on the cable compartment 1, a mechanism compartment panel 6 is mounted on one side of the mechanism compartment 3, the control box compartment 4 is mounted on the mechanism compartment 3, the sealing mechanism 9 is mounted on the mechanism compartment 3 for sealing, and multiple sets of connecting mechanisms 8 are provided, all mounted on the mechanism compartment 3, for connecting the mechanism compartment 3 and the mechanism compartment panel 6. Preferably, as shown... Figure 2 As shown, the connecting mechanism 8 is provided in three sets at equal intervals; In this embodiment, the cable compartment 1, the air box compartment 2, the mechanism compartment 3, and the control box compartment 4 constitute a complete ring main unit. The mechanism compartment panel 6 is equipped with secondary components such as knobs, lighting buttons, fault indicators, live indicators, silkscreen lines for the main bus and branch bus, air pressure observation windows, electromagnetic locks, and operating hole covers. These are existing technologies and will not be described in detail. The sealing mechanism 9 improves the sealing effect of the mechanism compartment 3, effectively blocking dust, water droplets, small solid foreign objects, etc. that enter in a straight direction, thus improving the performance of the ring main unit mechanism compartment 3. The connecting mechanism 8 facilitates the connection and separation of the mechanism compartment 3 and the mechanism compartment panel 6, while also expanding the opening angle of the mechanism compartment panel 6 from the traditional 130° to 180°, making it convenient for maintenance personnel to carry out maintenance.

[0022] Please refer to the specific details. Figure 1-3 and Figure 6 As shown, the mechanism chamber 3 is composed of two mechanism chamber side plates 31, a mechanism chamber top plate 32, and a mechanism chamber bottom plate 33. The mechanism chamber bottom plate 33 is installed on the top of the cable chamber 1, the two mechanism chamber side plates 31 are symmetrically installed on the top of the mechanism chamber bottom plate 33, and the mechanism chamber top plate 32 is installed between the tops of the two mechanism chamber side plates 31.

[0023] In this embodiment, the side panel 31, top panel 32, and bottom panel 33 of the mechanism chamber are all made of sheet metal. One side of each of the two side panels 31, top panel 32, and bottom panel 33 is bent. After the side panels 31, top panel 32, and bottom panel 33 are assembled, the bent part forms a water guide channel, including a horizontal water guide channel and a vertical water guide channel. The horizontal water guide channel and the vertical water guide channel are connected and the connection is a sealed and seamless connection. The vertical water guide channel is connected to the outside, ensuring that condensation droplets in the ring main unit cannot enter the interior of the mechanism chamber 3. Through the seamless connection of the water guide channel in all directions, together with the sealing mechanism 9, the water seepage risk caused by the splicing gap is completely eliminated, improving the overall protection level of the mechanism chamber 3, which is suitable for harsh environments such as high humidity and dust.

[0024] Please refer to the specific details. Figure 6-7 As shown, the sealing mechanism 9 includes multiple sealing strips 91, which are respectively installed on the outer wall of one side of the mechanism chamber side plate 31, the mechanism chamber top plate 32, and the mechanism chamber bottom plate 33.

[0025] In this embodiment, the sealing strip 91 has a U-shaped cross section and is respectively fitted and fixed to the corresponding bending parts of the side plate 31, top plate 32, and bottom plate 33 of the mechanism chamber. The sealing strip 91 and the panel 6 of the mechanism chamber are in close contact, effectively blocking dust, water droplets, small solid foreign objects, etc. that enter in a straight direction, thus improving the sealing effect of the mechanism chamber 3. At the same time, the bending parts of the side plate 31, top plate 32, and bottom plate 33 of the mechanism chamber can block some intruders that enter through the tiny gap between the panel 6 and the mechanism chamber 3, significantly improving the protection capability and environmental adaptability of the equipment.

[0026] Please refer to the specific details. Figure 2-5 As shown, the connecting mechanism 8 includes a fixed seat 81, which is fixedly installed on the outer wall of the mechanism chamber 3. A rotating shaft 83 is rotatably embedded in the outer wall of the fixed seat 81. An upper rotating hinge 84 and a lower rotating hinge 85 are sleeved on the outer surface of the rotating shaft 83. The upper rotating hinge 84, the lower rotating hinge 85 and the mechanism chamber panel 6 are all fixedly connected. A connecting shaft 86 is embedded between the upper rotating hinge 84 and the lower rotating hinge 85. Two connecting copper sleeves 82 are sleeved on the outer surface of the rotating shaft 83.

[0027] In this embodiment, the fixed base 81, rotating shaft 83, upper rotating hinge 84, lower rotating hinge 85, and connecting shaft 86 are all made of zinc-nickel alloy. The fixed base 81 is fixed to the outer wall of the mechanism chamber 3, and the upper rotating hinge 84 and lower rotating hinge 85 are fixed to the mechanism chamber panel 6. The fixed base 81 is hinged to the upper rotating hinge 84 and lower rotating hinge 85 through the rotating shaft 83. The connecting copper sleeve 82 serves as a guide sleeve, located on both sides of the fixed base 81, and has a limiting effect. The connecting shaft 86 connects the upper rotating hinge 84 and lower rotating hinge 85, enabling the upper rotating hinge 84 and lower rotating hinge 85 to rotate synchronously. The opening angle of the mechanism chamber panel 6 is extended from the traditional 130° to 180° through the connecting mechanism 8, maximizing the operating space of the mechanism chamber 3. Wiring personnel can access the terminal blocks and cables inside the mechanism chamber 3 without obstruction, avoiding difficulties in tool operation or blind spots caused by angle limitations, and greatly reducing the risk of misconnection and omission. It is especially suitable for dense wiring scenarios.

[0028] Please refer to the specific details. Figure 6-8 As shown, each upper rotary hinge 84 and lower rotary hinge 85 has multiple mounting screws 10 on its outer wall.

[0029] In this embodiment, the upper rotating hinge 84 and the lower rotating hinge 85 are installed and fixed by mounting screws 10. The screw heads of each mounting screw 10 are knurled, which makes it easy to tighten or remove manually without the need for special tools. When it is necessary to remove the mechanism chamber panel 6, the mounting screws 10 can be removed manually. After the maintenance is completed, they can be manually fixed back on, which improves the maintenance efficiency of the mechanism chamber 3.

[0030] Please refer to the specific details. Figure 1 As shown, a control panel 5 is installed on one side of the outer wall of the control box compartment 4.

[0031] In this embodiment, the control box panel 5 is installed on the control box chamber 4 to protect various secondary components inside the control box chamber 4.

[0032] Please refer to the specific details. Figure 1 As shown, a cable room door 7 is installed on one side of the outer wall of the cable room 1.

[0033] In this embodiment, the cable compartment door 7 provides protection for the cable compartment 1 to prevent accidental entry into the energized area.

[0034] Working principle: In the initial state, the mechanism chamber panel 6 is rotatably connected to the mechanism chamber 3 via the connecting mechanism 8. Simultaneously, multiple external screws (not shown in the diagram) lock the side of the mechanism chamber panel 6 away from the connecting mechanism 8. During maintenance of the ring main unit's mechanism chamber 3, simply remove the external screws on the side of the mechanism chamber panel 6 away from the connecting mechanism 8 to allow the mechanism chamber panel 6 to rotate and open around the connecting mechanism 8. The mechanism chamber panel 6 and all its components remain connected as a whole, and the secondary wiring does not require any disassembly. After maintenance, the mechanism chamber panel 6 and the mechanism chamber 3 are then reconnected. After the chamber 3 is fitted, tighten the external screws on the side away from the connecting mechanism 8. During maintenance, the connecting mechanism 8 expands the opening angle of the mechanism chamber panel 6 from the traditional 130° to 180°, maximizing the operating space of the mechanism chamber 3. Wiring personnel can access the internal terminal blocks and cables of the mechanism chamber 3 without obstruction. When the mechanism chamber panel 6 needs to be disassembled during major maintenance, the mounting screws 10 can be unscrewed by hand to remove the mechanism chamber panel 6 as a whole. After maintenance, simply connect the mechanism chamber panel 6 and the mechanism chamber 3 through the connecting mechanism 8 using the mounting screws 10. The mechanism chamber 3 consists of two mechanism chamber side plates 31, a mechanism chamber top plate 32, and a mechanism chamber bottom plate 33. One side of each of the two mechanism chamber side plates 31, the mechanism chamber top plate 32, and the mechanism chamber bottom plate 33 is bent. After the mechanism chamber side plates 31, the mechanism chamber top plate 32, and the mechanism chamber bottom plate 33 are assembled, the bent part forms a water guide channel, including a horizontal water guide channel and a vertical water guide channel. Through the seamless connection of the water guide channel in all directions, together with the sealing mechanism 9, the water seepage risk caused by the splicing gap is completely eliminated, and the overall protection level of the mechanism chamber 3 is improved.

[0035] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
