Description

Technical Field

[0001] The present invention provides an electric power basic resource management and control system, belonging to the technical field of electric power basic resource management and control. Background Art

[0002] The power infrastructure resource management and control system is a vital component of the distribution network system. It is used to balance power supply (power plant output, energy storage discharge, purchased electricity, etc.) with power demand (user load) in real time in the most economical, efficient, and environmentally friendly manner, while ensuring the safe and stable operation of the power grid, to meet ever-changing electricity needs. The high-voltage circuit breakers used in the power infrastructure resource management and control system are key protection devices, installed at substations and important transmission and distribution nodes. When a system fault occurs (such as a short circuit or ground fault), they can extremely quickly and reliably cut off the fault current, isolating the faulty equipment or line from the power grid, acting as a safety switch to prevent the fault from spreading and causing large-scale power outages or equipment damage. The installed circuit breakers must be capable of withstanding high voltages, large currents, and rapid arc extinguishing.

[0003] In order to achieve arc extinguishing control, the high-voltage circuit breakers currently used move the lower contact downward and separate from the upper joint, which increases the pressure of the sulfur hexafluoride below. The sulfur hexafluoride moves upward and fills the chamber, and then comes between the two contact points to extinguish the arc. During the entire arc extinguishing process, the sulfur hexafluoride gas needs to slowly increase its pressure as the lower contact moves downward. In addition, since the channel above the lower contact is narrow, the speed at which the sulfur hexafluoride fills the chamber is slow, which prolongs the arc extinguishing time. When an emergency occurs, the arc cannot be extinguished quickly, which will cause serious accidents in the distribution network. Summary of the Invention

[0050] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0051] like Figures 1 to 11 As shown, an electric power infrastructure resource management and control system proposed in one embodiment of the present invention includes a circuit breaker body 1 and an inner main sleeve 4 arranged inside the circuit breaker body 1, wherein the inner main sleeve 4 has an upper and lower structure, namely an upper contact copper sleeve 5 at the top and a lower contact copper sleeve 7 below the upper contact copper sleeve 5, wherein an upper contact body 6 extending downward by one end is fixedly provided in the upper contact copper sleeve 5, wherein an upper contact sleeve 9 that can be sleeved on the outside of the upper contact body 6 is installed in the lower contact copper sleeve 7, and when the lower contact copper sleeve 7 and the upper contact sleeve 9 move upward , and finally the upper contact sleeve 9 is sleeved on the outside of the upper contact body 6 to achieve communication. Conversely, when the lower contact copper sleeve 7 moves downward, the upper contact sleeve 9 detaches from the bottom of the upper contact body 6, and the entire inner main sleeve 4 cavity is filled with sulfur hexafluoride. Due to the action of gravity, the sulfur hexafluoride is located at the bottom of the inner main sleeve 4 cavity. As the lower contact copper sleeve 7 and the upper contact sleeve 9 move downward, the sulfur hexafluoride at the bottom will move upward due to the pressure and fill the inner main sleeve 4 cavity from the gap above the lower contact copper sleeve 7, thereby using sulfur hexafluoride to extinguish the arc and complete the circuit breaking work.

[0052] Among them, the bottom of the upper contact sleeve 9 is connected to the bottom of the lower contact copper sleeve 7 through a bracket, so that the lower contact copper sleeve 7 and the upper contact sleeve 9 can move synchronously, and the bottom of the upper contact sleeve 9 is fixedly connected to the insulating connecting part 10, and a connecting part side hole 12 is opened horizontally through the surface of the insulating connecting part 10, and a circular hole is opened at the bottom of the insulating connecting part 10, wherein the insulating connecting rod 11 can move up and down in the circular hole, and the part of the insulating connecting rod 11 extending into the cavity of the connecting part side hole 12 is fixed with an insulating adjustment rod 13 extending to both sides to the outside of the groove of the connecting part side hole 12. When the insulating connecting rod 1 When the insulating rod 11 moves up and down, it pushes the insulating adjustment rod 13 to move up and down in the groove of the connecting part side hole 12. When the insulating adjustment rod 13 is located at the top of the groove of the connecting part side hole 12, as the insulating connecting rod 11 continues to move upward, it can push the insulating connecting part 10, thereby causing the lower contact copper sleeve 7 and the upper contact sleeve 9 connected to the top of the entire insulating connecting part 10 to move upward. Conversely, when the insulating connecting rod 11 moves downward, the insulating adjustment rod 13 presses against the bottom of the groove of the connecting part side hole 12 and moves downward, thereby pulling the insulating connecting part 10 downward, thereby realizing the separation and connection of the upper contact sleeve 9 and the upper contact body 6.

[0053] The inner main sleeve 4 cavity is filled with sulfur hexafluoride. When the insulating connection part 10 moves downward, causing the lower contact copper sleeve 7 and the upper contact sleeve 9 to move downward, the pressure of the sulfur hexafluoride at the bottom of the inner main sleeve 4 increases and moves upward along the channel between the lower contact copper sleeve 7 and the upper contact sleeve 9, and enters between the upper contact copper sleeve 5 and the lower contact copper sleeve 7. At this time, after the upper contact sleeve 9 is separated from the end of the upper contact body 6, the arc can be extinguished by sulfur hexafluoride to complete the circuit breaking. On the contrary, when the upper contact sleeve 9 and the lower contact copper sleeve 7 move upward, the sulfur hexafluoride uses its own downward movement characteristics to return to its initial position downward from between the upper contact body 6 and the upper contact sleeve 9. A drainage outlet is provided at the bottom of the groove of the upper contact sleeve 9 to allow the sulfur hexafluoride to move. After the upper contact sleeve 9 and the upper contact body 6 reach the designated connection point, the sulfur hexafluoride is at the lower position of the gap between the lower contact copper sleeve 7 and the upper contact sleeve 9. An upper contact top cover 8 is fixed on the top of the lower contact copper sleeve 7, wherein the top of the upper contact top cover 8 adopts a downward conical design, and a circular hole allowing the upper contact body 6 to pass through is provided in the center of the upper contact top cover 8. The circular hole is used for the movement of sulfur hexafluoride and at the same time provides a positioning effect for the combination of the upper contact body 6 and the upper contact sleeve 9.

[0054] The lifting plate 23 is attached to the bottom of the inner main sleeve 4, that is, sulfur hexafluoride is gathered above the lifting plate 23, and a plate top groove 20 is provided on the top of the lifting plate 23. A top groove slider 21 is slidably connected in the groove of the plate top groove 20. The bottom of the insulating connection part 10 and the top groove slider 21 are connected by a linkage structure. The side of the linkage structure is equipped with a rotating support rod part 19 fixedly connected to the inner wall of the inner main sleeve 4. The linkage structure can realize the synchronization of the insulating connection part 10 and the lifting plate 23. The linkage structure includes a lower support rod 14, an adjustment horizontal plate 15 and an adjustment vertical plate 18, wherein the lower support rod 14 is fixed at the bottom of the insulating connecting portion 10, the adjustment vertical plate 18 is connected to the top of the top groove slider 21, the adjustment horizontal plate 15 is connected between the lower support rod 14 and the adjustment vertical plate 18, and the surface of the adjustment horizontal plate 15 is provided with a horizontal plate track groove 16. The bottom end bending portion of the lower support rod 14 is fixed with an adjustment slider 17 that slides along the horizontal plate track groove 16, and the adjustment horizontal plate 1 5 is fixedly connected to the adjustment vertical plate 18, wherein one end of the rotating support rod 19 is fixedly arranged on the inner wall of the inner main sleeve 4, and the other end of the rotating support rod 19 is rotatably connected to the connection between the adjustment horizontal plate 15 and the adjustment vertical plate 18. When the insulating connecting portion 10 moves downward, it presses the lower support rod 14 to move downward. At this time, the adjusting slider 17 at the end of the lower support rod 14 presses the groove of the horizontal plate track 16 downward, thereby forcing the adjustment horizontal plate 15 to rotate downward with the rotating support rod 19 as the rotation axis, and the adjustment vertical plate 18 rotates with the rotating support rod. Part 19 rotates upward as the rotating shaft, and the bottom of the adjusting vertical plate 18 is connected to the top groove slider 21 through the slider rotating shaft 22, and the top groove slider 21 slides horizontally along the groove of the top groove 20 of the pressure plate and cannot be detached. Therefore, under the drag of the adjusting vertical plate 18, the entire lifting pressure plate 23 will move upward, thereby realizing the downward pressure of the lower contact copper sleeve 7 and the upper contact sleeve 9 combined with the rising of the lifting pressure plate 23, giving sulfur hexafluoride more efficient pressure transmission, so that sulfur hexafluoride can move upward more quickly and perform arc extinguishing work.

[0055] The adjusting slider 17 is a columnar structure, and the groove shape of the cross plate track groove 16 is adapted to the adjusting slider 17, so that the adjusting slider 17 can move freely in the groove of the cross plate track groove 16 while the angle of the adjusting cross plate 15 and the adjusting slider 17 can be freely adjusted, and the linkage structure is symmetrically arranged above the lifting pressure plate 23, so that the up and down movement of the lifting pressure plate 23 is more stable.

[0056] The bottom of the circuit breaker body 1 is connected to the functional compartment 30, wherein the functional compartment 30 is mounted using the circuit breaker bracket 2 at the bottom. A mechanical control box 3 is also installed at the bottom center of the circuit breaker bracket 2, so that the mechanical controller inside the mechanical control box 3 is connected to the insulation adjustment rod 13, so that the trigger push rod 31 passes through the mechanical control box 3 upward, and there is also a plunger system in the mechanical control box 3. The plunger system presses against the lock to complete the locking of the trigger push rod 31. When there is a problem in the circuit, the current transformer will increase. When there is a problem in the circuit, the current transformer will increase. The abnormal situation is sent to the relay, and the plunger of the relay will extend outward to release the lock. After the lock is released, the spring elasticity at the bottom of the trigger push rod 31 is released, which will drive the trigger push rod 31 to move upward to complete the above-mentioned up and down movement of the insulating connection part 10. The mechanical controller and plunger system inside the mechanical control box 3 are existing technical solutions, which can restore the position of the lock and compress the spring to wait for subsequent triggering. At the same time, the sliding of the insulating connecting rod 11 at the bottom of the inner main sleeve 4 also adopts the existing known sliding sealing component technical solution.

[0057] An air flow hole 24 is longitudinally penetrated on the surface of the upper contact top cover 8, and a socket is provided at the bottom of the upper contact top cover 8 to allow the insulation adjustment rod 13 to extend from its bottom, and the upper contact body 6 and the center hole of the upper contact top cover 8 are located in the same vertical direction, wherein the insulation adjustment rod 13 is bent and then passes upward through the socket to extend into the internal cavity of the upper contact top cover 8, and an air flow cover plate 25 is installed in the cavity, and a transverse hole is also provided in the upper contact top cover 8 to allow the air flow cover plate 25 to pass through laterally. When the air flow cover plate 25 moves toward the air flow hole 24 in the transverse hole, the channel of the air flow hole 24 can be covered, and a guide plate 26 is fixed to the rear end of the air flow cover plate 25, and the bottom of the guide plate 26 has an inclined portion, and the inclined portion has a plate rail groove 27, and a toggle slider 28 is slidably connected in the groove of the plate rail groove 27, and the bottom of the toggle slider 28 is connected to the bottom of the insulation adjustment rod 13 by a rotating shaft;

[0058] When the insulation adjustment rod 13 moves upward at the bottom of the groove of the connecting part side hole 12, the toggle slider 28 connected to the top of the insulation adjustment rod 13 will push the guide plate 26 in the groove of the plate rail groove 27. Due to the longitudinal movement characteristics of the insulation adjustment rod 13 and the lateral movement characteristics of the airflow cover 25, the guide plate 26 pushes the airflow cover 25 to move to the left. When the insulation adjustment rod 13 is located at the top of the groove of the connecting part side hole 12, the airflow cover 25 completely covers the airflow hole 24 channel to close the channel. Conversely, when the insulation adjustment rod 13 moves down to the bottom of the groove of the connecting part side hole 12, the insulation adjustment rod 13 drags the guide plate 26 downward to make the airflow cover 25 return, so that the internal channel of the airflow hole 24 is opened. The opened airflow hole 24 can assist the center hole of the upper contact top cover 8 to complete the movement of sulfur hexafluoride.

[0059] The insulating connecting rod 11 passes through the bottom of the inner main sleeve 4 and extends into the functional chamber 30, and the bottom of the insulating connecting rod 11 is rotated to connect to the mechanical rocker arm 36, wherein the bottom of the mechanical rocker arm 36 is rotatably connected to the rotating turntable 34, and the mechanical rocker arm 36 is connected to the outer ring area of ​​the rotating turntable 34. Each set of functional chambers 30 is connected to the rotating turntable 34 and the mechanical rocker arm 36, and corresponds to the insulating connecting rod 11 one by one, and multiple sets of rotating turntables 34 are connected by the synchronous center rod 29, so that the multiple sets of rotating turntables 34 can rotate synchronously. A gear ring portion 35 is provided on the surface of the rotating turntable 34, and a small gear 33 meshing with the gear ring portion 35 is also provided in the functional chamber 30, wherein the extended end of the rotating shaft connected to the pinion 33 is installed with an outer rotating sleeve 32, and the surface of the outer rotating sleeve 32 is connected to the trigger push rod 31 through the rotating shaft. When the trigger push rod 31 moves upward, it will drag the outer rotating sleeve 32 to rotate, thereby rotating the pinion 33. After the pinion 33 rotates, it drives the rotating turntable 34 to rotate, thereby causing the mechanical rocker arm 36 to move in conjunction with the insulating connecting rod 11.
