Description

Technical Field

[0001] The present invention relates to the technical field of outdoor circuit breakers, and more specifically to an outdoor high-voltage AC intelligent vacuum circuit breaker. Background Art

[0002] In the power system, outdoor high-voltage AC vacuum circuit breakers are one of the key devices to ensure stable power transmission and distribution. With the continuous growth of power demand and the expansion of power grid construction to a wider range of regions, higher requirements are placed on the performance and adaptability of vacuum circuit breakers.

[0003] At present, in some special outdoor installation geological environments, such as deserts, Gobi, high-altitude mountainous areas, etc., existing vacuum circuit breakers have exposed many problems. For example, in areas with high temperature, heavy rain and snow, and large temperature differences, existing vacuum circuit breakers cannot meet the assembly layout requirements in this scenario. High temperature environment will reduce the performance of the insulating material inside the vacuum circuit breaker, accelerate the aging of components, and reduce the service life of the equipment. On the one hand, more rain and snow may cause rainwater to penetrate into the equipment, causing faults such as short circuits; on the other hand, the humid environment will cause metal parts to rust and corrode, affecting the mechanical and electrical properties of the equipment. In addition, the large temperature difference will cause the various components of the equipment to have different degrees of thermal expansion and contraction, resulting in loose connections, reduced sealing performance, and other problems, which will lead to frequent damage to the equipment.

[0004] Under the conditions of this region, maintenance is also difficult and costly. Due to the remote location or harsh environment, it is difficult for maintenance personnel and equipment to reach the site quickly, which increases the power outage time and causes great economic losses to users. At the same time, the special equipment and protective measures required for maintenance also increase the maintenance cost. Moreover, frequent maintenance not only affects the normal operation of the power system, but may also cause hidden dangers in the equipment after maintenance and cannot be restored to the optimal performance state.

[0005] In summary, existing vacuum circuit breakers have many defects in outdoor environments with high temperature, heavy rain and snow, and large temperature differences. There is an urgent need for an intelligent outdoor high-voltage AC vacuum circuit breaker to meet the assembly and layout requirements in special environments. In view of this, we propose an outdoor high-voltage AC intelligent vacuum circuit breaker. Summary of the invention

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The present invention improves the structure of the existing outdoor vacuum circuit breaker by arranging three groups of insulators on the shell, a vacuum arc extinguishing chamber is arranged inside the insulator, a dual-state shielding mechanism is arranged at the top of the insulator and the vacuum arc extinguishing chamber, and a top protection mechanism is arranged at the top of the dual-state shielding mechanism. The driving component and the clutch component of the dual-state shielding mechanism cause the rotating component to drive the rotating component to rotate, and the rotating component drives the shielding component and the heat dissipation component to rotate and deform to form a rain and snow shielding state or a high-temperature dissipation state. One form improves the protection properties of the circuit breaker while ensuring heat dissipation, and the other form reduces the difficulty of maintenance under the premise of efficient heat dissipation, which is conducive to flexible switching of working states according to actual environment, improves the adaptability of equipment to complex environment, broadens the scope of application, promotes the intelligent development of power grids, and improves the level of power grid intelligence and management efficiency.

[0021] 2. In the present invention, the whole rotation gear is rotatably arranged on the top of the supporting top plate. When the driving gear drives the whole rotation gear to rotate, the whole rotation gear drives the adjusting gear A, the three-arc bracket, the adjusting gear B and the rotating rod to rotate as a whole; when the driving gear drives the adjusting gear A to rotate, since the adjusting gear A and the adjusting gear B are fixedly connected, the rotation of the adjusting gear A drives the adjusting gear B to rotate, and the rotation of the adjusting gear B engages and drives the rotating component to rotate, thereby realizing the switching between the two forms; the driving structure of the present invention is compactly designed, and the connection between the components is firm, which can effectively resist the interference of external environmental factors, such as vibration, impact, etc.; in harsh outdoor environments, the equipment can still maintain a stable operating state, reducing the risk of equipment damage and shutdown due to drive system failure, and improving the reliability and stability of the equipment.

[0022] 3. In the present invention, the integral gear is rotatably arranged at the top of the supporting top plate. When the driving gear drives the integral gear to rotate, the integral gear drives the adjusting gear A, the three-arc bracket, the adjusting gear B, the rotating rod, the rotating assembly, the shielding assembly and the heat dissipation assembly to rotate as a whole; it can stir the surrounding air more quickly, accelerate the flow speed of the air, and form a stronger convection effect. This efficient air flow can promptly take away a large amount of heat generated by the equipment, rapidly reduce the temperature inside the equipment, and ensure that the equipment always remains within a safe operating temperature range in a high temperature environment.

[0023] 4. In the present invention, the heat generated by arc extinguishing in the vacuum arc extinguishing chamber is first diffused through a larger specific surface area through the bottom heat sink, and then efficiently dispersed through the higher top heat sink connected to the oblique blocks thereon. The triangular corner grooves formed by the three groups of bottom heat sinks and top heat sinks can guide the air to form relative flow paths, thereby promoting air convection around the heat sink. The flow of air can promptly take away the hot air on the surface of the heat sink, allowing cold air to be continuously replenished, forming a good heat exchange cycle, and further improving the heat dissipation efficiency.

[0024] 5. In the present invention, the push plate and the sleeve are driven to slide on the pillar by the stroke of the driving cylinder B, and the movable groove provided on the sleeve moves. Since the insertion rod on the top defense plate is rotatably inserted in the rotation slot and the adjustment rod is movably inserted in the movable groove, when the sleeve drives the movable groove to move, the displacement of the adjustment rod causes the top defense plate to deflect to adapt to the rain and snow shielding state or the high temperature dissipation state of the dual-state shielding mechanism. In the rain and snow shielding state, a plurality of top defense plates are parallel to achieve shielding of rain and snow to improve the protection, which greatly reduces the erosion of rain and snow on the equipment, avoids the problems of short circuit caused by rainwater infiltration into the interior of the equipment, rust and corrosion of metal parts caused by moisture, and significantly improves the protection ability of the equipment in severe rain and snow weather; in the high temperature dissipation state, a plurality of top defense plates are tilted, which not only dumps the rain and snow accumulated on the top defense plates, but also facilitates the sunlight to enter the interior of the unfolded dual-state shielding mechanism, and uses the heat of the sunlight to accelerate the flow of water vapor and air inside the equipment, promote the dissipation of heat, and further improves the heat dissipation efficiency of the equipment in a high temperature environment, ensuring that the equipment can maintain good working performance even in hot weather.
