Abstract
Description
Technical Field
[0001] This utility model relates to the field of ring network switchgear technology, specifically a ring network switchgear designed to prevent misoperation. Background Technology
[0002] Ring main unit (RMU) switchgear is an important piece of equipment in power distribution systems, primarily used for power distribution, protection, and control. It connects multiple power sources through a ring network structure, thereby improving the reliability and flexibility of power supply. RMU switchgear typically integrates electrical components such as disconnectors, load switches, and circuit breakers, enabling automatic power switching, fault isolation, and system protection. This equipment is widely used in urban power systems, industrial parks, commercial buildings, and other locations, especially in situations requiring enhanced power supply security and stability. Modern RMU switchgear also features intelligent control and remote monitoring capabilities, allowing for real-time monitoring of the power grid's operating status, improving management efficiency and safety.
[0003] Ring mains switchgear is typically installed outdoors for easy maintenance and control of power systems. However, due to its unique design, the unlocking method of the cabinet doors is relatively simple, which may pose certain safety hazards. First, ring mains switchgear usually uses traditional mechanical locks or simple knob locks. This unlocking method is easy to use and lacks complex protective measures, making it easy for unqualified personnel to misoperate or open it at will. Second, the overly simple unlocking method may allow unauthorized personnel to enter the cabinet, thereby damaging the equipment inside or interfering with the normal operation of the power system. Third, if there are no timely security monitoring measures in the surrounding environment, the risk of misoperation or malicious operation will be greatly increased, thus affecting the stability and security of the entire power grid. Finally, ring mains switchgear is often located in remote areas or open locations where there is a lack of professional power personnel to manage it, and the lax unlocking method makes the equipment more susceptible to external interference.
[0004] To address the aforementioned issues, we have made improvements and proposed a ring network switchgear designed to prevent misoperation. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a ring network switch cabinet for preventing misoperation, comprising a cabinet body, a first cabinet door movably connected to the left side of the front surface of the cabinet body via a hinge, and a second cabinet door movably connected to the right side of the front surface of the cabinet body via a hinge.

The guide rod moves the plug rod to the right through the movable plate, so that the right side of the plug rod is inserted into the inner cavity of the slot. After the strong magnetic block is removed, the overall structure cannot be opened from the outside, thus significantly reducing the risk of misoperation by external personnel.
[0013] 2. This anti-misoperation ring main switchgear, by setting sliders and grooves, can effectively improve the smoothness of the moving plate and guide rod during horizontal movement. By setting blocks and slots, it can limit the magnetic pull plate and guide rod, effectively improving the insertion effect between the plug and the slot. By setting through holes, it can guide the plug. By setting guide grooves, it can guide the movement trajectory of the strong magnetic block.

[0021] Please see Figure 1-4A ring main switch cabinet for preventing misoperation includes a cabinet body 2. A first cabinet door 4 is movably connected to the left side of the front surface of the cabinet body 2 via a hinge, and a second cabinet door 5 is movably connected to the right side of the front surface of the cabinet body 2 via a hinge. A fixed seat 8 is fixedly connected to the back side of the first cabinet door 4, and a limit seat 9 is fixedly connected to the back side of the second cabinet door 5. A guide hole 21 is provided on the left side of the fixed seat 8, and a guide rod 10 is provided through the inner cavity of the guide hole 21. A reset spring 11 is sleeved on the surface of the guide rod 10. A movable plate 12 is fixedly connected to the right side of the guide rod 10. Insert rods 13 are fixedly connected to the top and bottom of the right side of the movable plate 12. Slots 14 are provided on the top and bottom of the left side of the limit seat 9, and the right side of the insert rod 13 is inserted into the inner cavity of the slot 14.
[0022] Through the above technical solution, the return spring 11, due to the loss of force, recovers its deformation and extends to the right, driving the guide rod 10 to move to the right. The guide rod 10, through the movable plate 12, drives the insertion rod 13 to move to the right, so that the right side of the insertion rod 13 is inserted into the inner cavity of the slot 14. After the strong magnetic block 7 is removed, the overall structure cannot be opened from the outside, thus significantly reducing the risk of accidental operation by external personnel.
[0023] Specifically, the top and bottom of the inner wall of the fixed base 8 are provided with sliding grooves 17, the top and bottom of the movable plate 12 are fixedly connected with sliders 16, and the sliders 16 are slidably connected in the inner cavity of the sliding grooves 17. The top and bottom of the right side of the fixed base 8 are provided with through holes 15, the right side of the insertion rod 13 passes through the inner cavity of the through hole 15 and extends to the right side of the fixed base 8, the left side of the guide rod 10 is fixedly connected with a magnetic pull plate 18, the middle of the front surface of the first cabinet door 4 is provided with a guide groove 6, the inner cavity of the guide groove 6 is movably connected with a strong magnetic block 7, the strong magnetic block 7 and the magnetic pull plate 18 are magnetically connected, the top and bottom of the right side of the magnetic pull plate 18 are fixedly connected with a locking block 19, the top and bottom of the left side of the fixed base 8 are provided with a locking groove 20, the locking block 19 is locked in the inner cavity of the locking groove 20, the bottom of the cabinet body 2 is fixedly connected with a waterproof base plate 1, and the top of the cabinet body 2 is fixedly connected with a guide plate 3.
[0024] Through the above technical solutions, by setting the slider 16 and the slide groove 17, the smoothness of the movable plate 12 and the guide rod 10 during horizontal movement can be effectively improved. By setting the locking block 19 and the locking groove 20, the magnetic pull plate 18 and the guide rod 10 can be limited, effectively improving the insertion effect between the insertion rod 13 and the slot 14. By setting the through hole 15, the insertion rod 13 can be guided. By setting the guide groove 6, the movement trajectory of the strong magnetic block 7 can be guided. By setting the waterproof base plate 1 and the guide plate 3, the waterproof effect of the cabinet 2 in the external environment can be effectively improved.
[0025] In use, first place the strong magnetic block 7 on the right side of the inner cavity of the guide groove 6. After the strong magnetic block 7 is magnetically connected to the magnetic pull plate 18, move the strong magnetic block 7 to the left. The strong magnetic block 7 uses magnetic force to drive the magnetic pull plate 18 to move to the left. The magnetic pull plate 18 drives the guide rod 10 to move to the left. The guide rod 10 drives the insertion rod 13 to move to the left through the movable plate 12. The insertion rod 13 is then retracted into the inner cavity of the fixed seat 8, making it convenient to open the first cabinet door 4 and the second cabinet door 5.
[0026] When closing and locking the first cabinet door 4 and the second cabinet door 5, the strong magnetic block 7 is first moved to the left. The strong magnetic block 7 drives the magnetic pull plate 18 to move to the left. The magnetic pull plate 18 drives the guide rod 10 to move to the left. The guide rod 10 causes the return spring 11 to deform and press to the left. Then the first cabinet door 4 and the second cabinet door 5 are closed. At this time, the strong magnetic block 7 is removed. The magnetic pull plate 18 is no longer affected by the magnetic force. At this time, the return spring 11 recovers its deformation due to the loss of force and extends to the right, driving the guide rod 10 to move to the right. The guide rod 10 drives the insertion rod 13 to move to the right through the movable plate 12, so that the right side of the insertion rod 13 is inserted into the inner cavity of the slot 14, making the overall structure unable to be opened from the outside, thereby significantly reducing the risk of accidental operation by external personnel (the above is the working process of the whole device.
