Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, specifically a split-type adjustable gap equalizing ball. Background Technology

[0002] During the operation of high-voltage electrical equipment, the equalizing sphere, as a key component for improving the electric field distribution and avoiding local electric field concentration, plays a vital role in the insulation performance and safe and stable operation of the equipment.

[0003] Most existing equalizing spheres are integral structures. During the installation and maintenance of large electrical equipment, their large size and excessive weight make transportation difficult, and the installation and disassembly processes are complex, greatly increasing labor and time costs. Moreover, the existing equalizing spheres have fixed gaps, making it difficult to adapt to the diverse electric field distribution requirements of different voltage levels and equipment structures. They cannot dynamically optimize the electric field when the equipment operating conditions change, posing a risk of insulation failure. Some equalizing spheres that adopt a split design rely heavily on bolt fastening for connection. This not only makes gap adjustment cumbersome, requiring repeated tightening and disassembly with various tools, but also makes the bolts prone to loosening and falling off under long-term vibration of the equipment, affecting the structural stability and equalizing effect of the equalizing sphere.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example

[0024] Please see Figure 1-5 This utility model provides a technical solution: a split-type adjustable gap equalizing ball, comprising:

[0025] The lower equalizing ball 1 and the upper equalizing ball 2 are symmetrically fixed to the outer walls of the lower equalizing ball 1 and the upper equalizing ball 2. The adjusting device 3 is quickly locked in an elastic manner. The inner wall of the adjusting device 3 is slidably connected to the unlocking device 4. The upper equalizing ball 2 and the lower equalizing ball 1 are installed through the adjusting device 3. In subsequent use, the adjusting device 3 is adjusted through the unlocking device 4 according to the current, so that the gap between the upper equalizing ball 2 and the lower equalizing ball 1 can be adjusted to a suitable position.

[0026] The adjusting device 3 includes a support block 30, and a slide rod 31 is slidably connected to the inner wall of the support block 30. The inner wall of the slide rod 31 is provided with a socket 32, and the inner wall of the socket 32 ​​is arranged in a linear array along the outer wall of the slide rod 31. The outer wall of the support block 30 is symmetrically fixedly connected to the outer walls of the lower equalizing ball 1 and the upper equalizing ball 2, and the inner wall of the support block 30 located on the outer wall of the upper equalizing ball 2 is slidably connected to the outer wall of the slide rod 31. When it is necessary to increase the gap, the upper equalizing ball 2 is pushed upward. Since the inner wall of the pin 33 is symmetrically slidably connected with the pin 33, the pointed design of the pin 33 allows it to automatically slide out of the socket 32 ​​when the slide rod 31 moves upward, and is locked into the next socket 32 ​​under the action of the elastic clip 34, realizing one-way automatic locking. The combination of the elastic clip 34 and the limiting rod 35 forms an elastic buffer structure, which absorbs energy when the equipment vibrates during operation and prevents the pin 33 from accidentally coming out.

[0027] The inner wall of the socket 32 ​​is symmetrically slidably connected with a pin 33, and the outer wall of the pin 33 is pointed. The end of the pin 33 away from the pointed end is fixedly connected with an elastic clip 34. The inner wall of the elastic clip 34 is fixedly connected with a limit rod 35. The bottom end of the elastic clip 34 is slidably connected to the inner wall of the outer wall support block 30 of the upper equalizing ball 2. The bottom end of the limit rod 35 is fixedly connected to the inner wall of the outer wall support block 30 of the upper equalizing ball 2.

[0028] The unlocking device 4 includes a paddle 40, a slider 41 fixedly connected to the outer wall of the paddle 40, and a groove 42 slidably connected to the outer wall of the paddle 40. The outer wall of the paddle 40 is symmetrically slidably connected to the outer wall of the elastic clamp 34. The outer wall of the slider 41 is slidably connected to the outer wall of the support block 30 of the upper equalizing ball 2. The groove 42 is symmetrically opened in the inner wall of the support block 30 of the upper equalizing ball 2. When it is necessary to adjust the gap between the upper equalizing ball 2 and the lower equalizing ball 1, the adjusting device 3 needs to be unlocked. At the same time, the paddles 40 of the unlocking devices 4 on both sides are paddled. Since the outer wall of the paddle 40 is symmetrically slidably connected to the inner wall of the support block 30, the slider 41 slides along the groove 42, causing the paddle 40 to squeeze the elastic clamp 34 to open. During this process, when the elastic clamp 34 opens, it causes the pin 33 to exit from the insertion hole 32, releasing the lock on the slide rod 31. Then, the paddle 40 is released.

[0029] During use, the upper equalizing ball 2 and the lower equalizing ball 1 are installed through the adjusting device 3. In subsequent use, the adjusting device 3 is adjusted through the unlocking device 4 according to the current magnitude so that the gap between the upper equalizing ball 2 and the lower equalizing ball 1 can be adjusted to a suitable position.

[0030] First, the upper equalizing ball 2 and the lower equalizing ball 1 are connected by a symmetrically distributed adjusting device 3. The slide rod 31 is inserted into the support block 30, and the pin 33 is inserted into the insertion hole 32 under the action of the elastic clip 34 to form an initial locking state, ensuring that the gap between the equalizing balls is fixed.

[0031] When it is necessary to adjust the gap between the upper equalizing ball 2 and the lower equalizing ball 1, the adjusting device 3 needs to be unlocked. At the same time, the levers 40 of the unlocking devices 4 on both sides are moved. Since the outer wall of the lever 40 is symmetrically connected to the inner wall of the support block 30, the slider 41 slides along the slide groove 42, which drives the lever 40 to squeeze the elastic clamp 34 to open it. During this process, when the elastic clamp 34 opens, it drives the pin 33 to exit from the insertion hole 32, releasing the lock on the slide rod 31. Then, the lever 40 is released.

[0032] When a larger gap is needed, push the upper equalizing ball 2 upward. Since the inner wall of the pin 33 is symmetrically connected to the pin 33, the pointed design of the pin 33 allows it to automatically slide out of the insertion hole 32 when the slide rod 31 moves upward, and then, under the action of the elastic clamp 34, engage with the next insertion hole 32, achieving one-way automatic locking. The combination of the elastic clamp 34 and the limiting rod 35 forms an elastic buffer structure, absorbing energy during equipment vibration and preventing the pin 33 from accidentally disengaging.

[0033] Conversely, when it is necessary to reduce the gap, the restriction of the adjusting device 3 can be released by the unlocking device 4, and the upper equalizing ball 2 can be moved downward so that the pin 33 is locked in the insertion hole 32 of the slide rod 31.
