Abstract
Description
Technical Field
[0001] This utility model relates to the field of protection technology, and in particular to a protective device for a static var generator. Background Technology
[0002] A static var generator (SVR) is a flexible AC transmission device based on fully controlled power electronic devices such as IGBTs. It belongs to the category of dynamic reactive power regulation devices in modern power systems. By controlling a bridge inverter circuit to dynamically inject or absorb reactive power, it achieves continuous bidirectional regulation of the grid's reactive current. Its core functions include improving the power factor, suppressing voltage flicker and harmonics, and optimizing power quality. It is widely used in industrial power consumption, new energy power generation, and distribution networks.
[0003] Most static var generators are placed indoors, while some special areas require them to be placed outdoors. Outdoor static var generators are protected by fences to prevent unauthorized personnel from accessing them. However, the protective capacity of the fences is low, and they are prone to collapse in the event of a collision, thus failing to protect the static var generator.
[0004] For example, if a static var generator is placed on the roadside for special reasons, a simple fence will not be able to stop the vehicle in the event of a collision, and the static var generator will still be damaged. The damage to the device may also cause leakage of electricity, posing a life threat to the people inside the vehicle. Utility Model Content
[0005] This utility model discloses a protective device for a static var generator, which aims to solve the technical problem that some static var generators placed outdoors in special areas are protected by fences to prevent unauthorized personnel from contacting them. However, the protective capacity of the fences is low and they are prone to collapse when a collision occurs, thus failing to protect the static var generator.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A protective device for a static var generator includes a lower base and an upper base fixed on top of it. A reinforcing seat is fixedly connected to the front top of the lower base, and a cabinet body is fixedly connected to the top of the upper base. A fixed railing is fixedly connected to the top edge of the lower base. The device also includes: an anti-collision mechanism: the anti-collision mechanism includes a rotating seat fixedly connected to the middle of the cabinet body, an anti-collision sleeve rotatably connected inside the rotating seat, a rotating railing provided on the front side of the rotating seat, and buckles fixedly connected to the left and right sides of the rotating railing, with a locking seat engaged on the outer side of each buckle; and a shielding mechanism: the shielding mechanism is fixedly connected to the top of the fixed railing.
[0008] In this solution, the anti-collision mechanism protects the cabinet and vehicle in the event of a collision. The fixed railing and rotating seat provide effective buffering and blocking when the cabinet is subjected to accidental collision or impact. At the same time, the anti-collision sleeve, through its rotating connection design, helps the vehicle to steer in the event of a collision, buffering the impact while providing more braking space for the vehicle, thus protecting the vehicle and the driver inside. The rotating seat's buckle-and-seat connection makes it easy to open, allowing operators to enter and operate the cabinet.
[0009] In a preferred embodiment, the shielding mechanism includes a mounting base disposed at the top rear side of the fixed fence, a fixed rod fixedly connected to the top of the mounting base, a reinforcing frame fixedly connected to the top of the fixed rod, a canopy fixedly connected to the top of the reinforcing frame, and a lightning rod fixedly connected to the top of the canopy.
[0010] In this solution, the shielding mechanism provides multi-level protection for the cabinet body. The canopy effectively shields against rain, snow, hail, and strong direct sunlight, preventing rainwater from seeping into the equipment and slowing down the aging of the equipment shell and internal components. At the same time, the lightning rod set on the top of the canopy forms a lightning strike point, which can safely guide the lightning current to the ground, greatly improving the operational safety of the equipment in thunderstorms and avoiding equipment damage and operational interruption caused by lightning strikes.
[0011] As described above, a protective device for a static var generator includes a lower base and an upper base fixed on top of it. A reinforcing seat is fixedly connected to the front top of the lower base, and a cabinet body is fixedly connected to the top of the upper base. A fixed rail is fixedly connected to the top edge of the lower base. The device also includes: an anti-collision mechanism: the anti-collision mechanism includes a rotating seat fixedly connected to the middle of the cabinet body, an anti-collision sleeve rotatably connected inside the rotating seat, a rotating rail on the front side of the rotating seat, and buckles fixedly connected to the left and right sides of the rotating rail, with a locking seat engaged on the outer side of each buckle; and a shielding mechanism: the shielding mechanism is fixedly connected to the top of the fixed rail. The protective device for a static var generator provided by this utility model has the technical effect of simultaneously protecting both the static var generator and the vehicle in the event of a vehicle collision.

[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0018] The protective device for a static var generator disclosed in this utility model is mainly used in scenarios where static var generators placed on the roadside need to be protected against collisions.
[0019] Reference Figure 1 , Figure 2 and Figure 3 A protective device for a static var generator includes a lower base 1 and an upper base 2 fixed on top of it. A reinforcing seat 3 is fixedly connected to the front top of the lower base 1, and a cabinet body 4 is fixedly connected to the top of the upper base 2. A fixed railing 5 is fixedly connected to the top edge of the lower base 1. The device is characterized by further including: an anti-collision mechanism: the anti-collision mechanism includes a rotating seat 6 fixedly connected to the middle of the cabinet body 4, an anti-collision sleeve 7 rotatably connected inside the rotating seat 6, a rotating railing 8 provided on the front side of the rotating seat 6, buckles 9 fixedly connected to the left and right sides of the rotating railing 8, and a buckle seat 10 snapped onto the outside of the buckle 9; and a shielding mechanism: the shielding mechanism is fixedly connected to the top of the fixed railing 5.
[0020] Specifically, the fixed railing 5 and the rotating seat 6 provide effective buffering and blocking when the cabinet body 4 is subjected to accidental collision or impact. At the same time, the anti-collision sleeve 7, through its rotating connection design, can help the vehicle to turn when a collision occurs, buffering the impact while increasing the braking space of the vehicle, thus protecting the vehicle and the driver inside. The connection between the buckle 9 and the seat 10 of the rotating seat 6 makes it easy to open the rotating seat 6, allowing operators to enter and operate the cabinet body 4.
[0021] There are twenty rotating seats 6 in total. Sixteen rotating seats 6 are fixedly connected at equal intervals in the middle of the fixed railing 5, and the other four rotating seats 6 are fixedly connected at equal intervals in the middle of the rotating railing 8. The anti-collision sleeve 7 is rotatably connected inside the rotating seats 6. The rotatably connected anti-collision sleeve 7 can buffer the impact when the vehicle hits its surface, and at the same time make the vehicle steer by friction, providing more braking space for the vehicle.
[0022] Among them, the rotating bar 8 is rotatably connected to the front top of the lower base 1 via a rotating shaft at the bottom. The rear bottom of the rotating bar 8 is attached to the inside of the reinforcing base 3. The card seat 10 is fixedly connected to the front of the fixed bar 5. The buckle 9 is snapped into the inside of the card seat 10. The detachable design of the buckle 9 and the card seat 10 makes it easy for workers to open the rotating bar 8 to operate the internal cabinet body 4.
[0023] Reference Figure 1 , Figure 2 and Figure 4 In a preferred embodiment, the shielding mechanism includes a mounting base 11 disposed on the top rear side of the fixed railing 5, a fixed rod 12 fixedly connected to the top of the mounting base 11, a reinforcing frame 13 fixedly connected to the top of the fixed rod 12, a canopy 14 fixedly connected to the top of the reinforcing frame 13, and a lightning rod 15 fixedly connected to the top of the canopy 14.
[0024] Specifically, the canopy 14 effectively shields against rain, snow, hail, and strong direct sunlight, preventing rainwater from seeping into the equipment and slowing down the aging of the equipment casing and internal components. At the same time, the lightning rod 15 installed at the top of the canopy 14 forms a lightning contact point, which can safely guide the lightning current to the ground, greatly improving the operational safety of the equipment in thunderstorms and avoiding equipment damage and operational interruption caused by lightning strikes.
[0025] The mounting base 11 is snapped onto the top of the fixing railing 5 and fixed with screws. There are four fixing rods 12, which are equidistantly fixed to the top of the mounting base 11. The canopy 14 is made of insulating plastic and has a water channel on the top. One end of the lightning rod 15 is fixed to the top of the canopy 14, and the other end is inserted into the ground. The multiple fixing rods 12 can increase the fixing effect of the canopy 14 in strong winds and prevent the fixing rods 12 from breaking. The water channel design on the top of the canopy 14 also facilitates the collection of rainwater on the top and its drainage.
[0026] Reference Figure 1 and Figure 4 In a preferred embodiment, both the lower base 1 and the upper base 2 are made of concrete, and the upper base 2 has a beveled edge design.
[0027] Specifically, the concrete-cast lower base 1 and upper base 2 can raise the height of the cabinet body 4, preventing rainwater from accumulating at the bottom and seeping into the interior of the cabinet body 4. The sloping edge of the upper base 2 facilitates the sliding of water droplets.
[0028] Working principle: When a vehicle collision occurs, the fixed railing 5 and the rotating seat 6 provide effective buffering and blocking when the cabinet body 4 is subjected to accidental collision or impact. At the same time, the anti-collision sleeve 7 can help the vehicle to turn. While buffering the impact, it can also increase the braking space of the vehicle, thus protecting the vehicle and the driver inside. The connection between the rotating seat 6 and the buckle 9 and the seat 10 makes it easy to open the rotating seat 6, allowing operators to enter and operate the cabinet body 4. The reinforcing seat 3 attached to the rear of the rotating seat 6 can reinforce the rotating seat 6 during an impact, preventing the rotating seat 6 from being knocked away. In rainy or snowy weather, the canopy 14 effectively shelters the equipment from rain and snow, preventing rainwater from seeping into the equipment. The raised lower base 1 and upper base 2 can raise the height of the cabinet body 4, preventing rainwater from seeping in from the bottom. At the same time, the lightning rod 15 set on the top of the canopy 14 forms a lightning strike point, which can safely guide the lightning current to the ground, avoiding equipment damage and operation interruption caused by lightning strikes.
[0029] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
