Description

Technical Field

[0001] This application relates to the technical field of power equipment safety protection, and in particular to a clamping anti-accidental contact isolation plate for the secondary circuit of a substation. Background Technology

[0002] Secondary equipment is a low-voltage electrical device used to monitor, control, measure, regulate, and protect the operating conditions of power systems and primary equipment. The electrical circuits formed by connecting secondary equipment together according to certain functional requirements are collectively referred to as secondary wiring or secondary circuits. It is an indispensable and important component to ensure the safe production, economical operation, and reliable power supply of power systems.

[0003] In existing technologies, secondary circuit terminals often employ simple isolation measures such as insulating sleeves and protective covers. However, these measures still have drawbacks. Traditional protective devices have loose structures that cannot securely hold the terminals, making them susceptible to loosening or detachment from external impacts. This can lead to operational risks such as malfunctioning protection and signal interruptions. Installation and disassembly require tools or cumbersome procedures, resulting in low efficiency, especially during emergency repairs, and increasing the maintenance burden. Enclosed protective structures also hinder heat dissipation from the terminals, which may accelerate equipment aging due to excessive temperature rise during long-term operation, and could even cause insulation failures.

[0017] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0018] This application discloses a clamping anti-accidental contact isolation plate for the secondary circuit of a substation. For example... Figure 1 As shown, the main body 1 includes a clamping structure 4, a heat dissipation structure 3 is provided on one side of the clamping structure 4, and a quick-release structure 2 is provided on one side of the heat dissipation structure 3. The quick-release structure 2 includes a locking latch 201, and a latch 202 is provided on one side of the locking latch 201; The heat dissipation structure 3 includes a fan cover 302, a fan 303 is movably connected inside the fan cover 302, and a perforated plate 301 is provided on one side of the fan 303; The clamping structure 4 includes a knob 401, a rotating ring 402 fixedly connected below the knob 401, a limiting block 403 below the rotating ring 402, a fixed shaft 405 on one side of the limiting block 403, a long rod 404 movably sleeved on the fixed shaft 405, and a clamping pad 406 at one end of the long rod 404.

[0019] It should be noted that the knob 401 drives the rotating ring 402, which in turn moves the long rod 404 along the fixed shaft 405, causing the limit block 403 to control the clamping pad 406 to form a stable clamp on the secondary circuit terminals. The clamping pad 406, made of elastic silicone material and featuring an anti-slip texture, prevents terminal displacement or loosening, avoids damage to the equipment, and effectively isolates the risk of accidental external contact. A perforated plate 301, a fan cover 302, and a built-in fan 303 are provided on one side of the clamping structure 4. The perforated plate 301 is located on the air inlet side, and the fan 303 directs the airflow directly towards the clamping area, forcing airflow through the dense terminal area to dissipate the heat generated during equipment operation in a timely manner, preventing excessive temperature rise that could lead to insulation aging or failure. A quick-connect mechanism, consisting of a locking latch 201 and a locking buckle 202, is located on the outside of the heat dissipation structure 3. The latch can be installed and removed in seconds without tools, significantly improving maintenance efficiency, especially suitable for emergency repair scenarios.

[0020] Please see Figures 1-3 The main body 1 includes an upper fixing plate 101, a middle fixing plate 102 is provided below the upper fixing plate 101, and a lower fixing plate 103 is provided below the middle fixing plate 102.

[0021] It should be noted that the upper fixing plate 101, middle fixing plate 102, and lower fixing plate 103, through their multi-layered structural design, primarily serve to provide layered fixing support for the secondary circuit cables. Their uniformly spaced openings ensure that the cables are evenly separated and positioned, effectively preventing displacement, entanglement, or loosening of the cables due to external forces or vibrations. This enhances the mechanical stability of the terminals, reduces the risk of terminal loosening or detachment due to accidental contact, and simultaneously ensures better airflow, preventing concentrated heat generation.

[0022] Please see Figures 1-3 The perforated plate 301 is located on the air inlet side of the fan cover 302, and the air outlet direction of the fan 303 is towards the clamping structure 4.

[0023] It should be noted that the perforated plate 301, as a protective structure on the air inlet side, blocks external foreign objects while ensuring that airflow enters the fan shroud 302 evenly. The fan 303 directs the cooling airflow towards the clamping structure 4, directly and actively dissipating heat from the heat-prone secondary circuit terminal area. By using forced air cooling to reduce the operating temperature, the problem of excessive temperature rise caused by traditional enclosed protection is avoided, thereby reducing the risk of insulation aging and equipment failure. The heat dissipation process does not interfere with the physical isolation function of the clamping structure 4, ensuring that the terminals remain firmly fixed even when accidentally touched by external force, thus meeting the dual requirements of safety protection and thermal management.

[0024] Please see Figures 5-6 The pad 406 is made of elastic silicone material, and its contact surface has anti-slip texture.

[0025] It should be noted that the 406 clamping pad utilizes the elastic deformation properties of silicone to tightly conform to the surface of secondary circuit terminals of different sizes or shapes, avoiding equipment damage caused by rigid clamping. The anti-slip texture on the contact surface significantly increases friction, preventing the terminals from slipping or loosening under external vibration or accidental contact, ensuring the clamping firmness. The silicone material itself has excellent insulation properties, further blocking the risk of electrical contact while isolating physical impacts.

[0026] Please see Figures 1-3 The locking mechanism 201 and the latch 202 work together to form a snap-fit ​​mechanism that can be quickly locked.

[0027] It should be noted that the locking 201 and locking buckle 202 work together to enable quick installation and removal of the isolation plate without the need for tools or complicated operations, significantly improving maintenance efficiency. At the same time, they ensure a secure connection of the device in the protected state, preventing accidental loosening due to external impacts. The simple operation of the mechanical snap-fit ​​ensures both the reliability of the protection and reduces the burden of maintenance.

[0028] Please see Figures 1-3 The upper fixing plate 101, the middle fixing plate 102 and the lower fixing plate 103 adopt a multi-layer structure to better fix the cable and prevent displacement.

[0029] It should be noted that the upper fixing plate 101, the middle fixing plate 102, and the lower fixing plate 103 enhance the constraint on the cable through the superimposed fixing layers, effectively limiting the risk of cable displacement under operation or external force. This design utilizes the synergistic clamping effect of the multi-layer plates to improve the stability of the cable within the isolation plate, avoiding terminal connection failure or accidental contact due to cable loosening, thereby ensuring the safe and reliable operation of the secondary circuit.

[0030] Please see Figures 1-3 The spacing between the openings of the two cables corresponding to the upper fixing plate 101, the middle fixing plate 102 and the lower fixing plate 103 is equal.

[0031] It should be noted that the upper fixing plate 101, middle fixing plate 102, and lower fixing plate 103 allow the cable to pass vertically through each fixing plate, ensuring uniform and stable force during clamping. This effectively prevents the cable from shifting or twisting within the device, while maintaining unobstructed heat dissipation channels and improving the overall structural reliability and protective effect. The equidistant openings ensure that the multi-layer clamping force is evenly distributed along the cable axis, avoiding localized stress concentration that could lead to terminal loosening or damage. Aligned holes form a through-channel, constraining lateral cable displacement and mitigating the risk of displacement due to external impacts. The neatly arranged cables prevent obstruction of airflow, optimizing heat dissipation efficiency. This complements the anti-displacement design of the multi-layer fixing plates, enhancing the overall clamping effect while ensuring better airflow and preventing concentrated heat generation.

[0032] The implementation principle of the clamping anti-accidental contact isolation buckle plate for the secondary circuit of a substation in this application embodiment is as follows: The secondary circuit cable is vertically passed through the three fixing plates of the main body 1 in sequence: upper fixing plate 101, middle fixing plate 102, and lower fixing plate 103. This ensures the cable passes through equally spaced openings on each plate, forming an aligned through-channel. The multi-layered structure evenly distributes the clamping force, preventing cable displacement or twisting while maintaining unobstructed heat dissipation channels. Rotating the knob 401 of the clamping structure 4 drives the fixedly connected rotating ring 402 to rotate. The rotating ring 402 drives the long rod 404 to move axially along the fixed shaft 405. The limiting block 403 pushes the clamping pad 406 at the end of the long rod 404 towards the cable terminal side. The elastic silicone pad 406 deforms to tightly adhere to the terminal surface, and its anti-slip texture enhances friction, preventing the terminal from loosening. The clamping force is controlled by the rotation angle of the knob 401, ensuring the terminal is stable and does not wobble, while avoiding excessive pressure that could damage the equipment. The perforated plate 301 is located on the air inlet side of the heat dissipation structure 3, blocking foreign objects and guiding airflow evenly into the fan shroud 302. After fan 303 starts, the airflow blows directly onto the densely packed terminal area of ​​clamping structure 4, forcibly cooling and reducing temperature rise. Directional heat dissipation avoids the heat accumulation problems caused by traditional enclosed protection, ensuring stable terminal operating temperature over the long term. The equidistant opening design of the multi-layer fixing plate prevents cables from obstructing airflow, optimizing heat dissipation efficiency. Dust accumulation on the perforated plate 301 and fan 303 needs to be cleaned regularly to maintain unobstructed airflow. Align the locking latch 201 and locking buckle 202 of quick-release structure 2, press and lock, achieving instant fixation of the plate. Disassembly requires manual separation of locking latch 201 and locking buckle 202; the plate can be quickly removed without tools. This significantly improves maintenance efficiency, especially suitable for rapid operation in emergency situations.

[0033] The clamping structure 4 achieves physical isolation of the terminals through mechanical linkage, resisting the risk of displacement caused by external accidental contact or vibration. The silicone clamping pad 406 also has insulation properties, blocking potential electrical contact hazards. The heat dissipation structure 3 actively cools down, preventing temperature rise from accelerating insulation aging, and does not interfere with the clamping function. The quick-release structure 2 simplifies the assembly and disassembly process, and the multi-layer fixing plate design reduces the frequency of daily maintenance. For the first installation, the correspondence between the rotation angle of the knob 401 and the clamping force should be tested to avoid being too loose or too tight. In high-temperature environments, the running time of the fan 303 can be increased; in low-temperature or low-load conditions, it can be run intermittently to save energy. Check the elasticity and anti-slip texture wear of the clamping pad 406 and replace it in time. Clean the gaps in the perforated plate 301 to ensure unobstructed airflow.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
