[0002] Substations are an indispensable link between power generation and power consumption. The power system is one of the pillar industries of the national economy. As an important part of it, substations play a pivotal role in changing voltage levels and gathering and distributing electric energy. As an important part of the power system, the technical origin of reactors can be traced back to the early days of the power industry. With the development of the power industry, reactor technology has also been continuously improved and innovated. Especially in recent years, with the rapid development of smart grids and new energy technologies, the performance requirements for reactors have become increasingly higher, which has promoted the continuous advancement of reactor technology.

[0003] Although reactor technology has made great progress, there are still some problems in practical applications.

The heat sink sockets 41 of the lower cover plate 5 are blind holes. The heat sink (not shown in the figure) is passed through the heat sink sockets 41 of the upper cover plate 4 from above and then falls into the heat sink sockets of the lower cover plate 5. Several heat sink sockets 41 on the upper and lower cover plates are provided along the circumferential direction of the cover plates, so that the reactor body is located inside several heat sinks, forming all-round heat dissipation for the reactor body, and reducing the temperature of the inductor during operation.

[0031] The seismic isolation support is arranged at the bottom of the lower cover plate 5, including a bottom plate 7 and a support plate 8 arranged up and down, and also includes a spring 9 and an active seismic isolation module arranged between the bottom plate 7 and the support plate 8, and a laminated rubber damping layer 11 arranged on the top of the support plate 8; the top of the laminated rubber damping layer 11 is fixedly connected to the lower cover plate.

[0032] The active seismic isolation module includes a plurality of vibration sensors arranged on the reactor device, a plurality of jacks 10 arranged on the top of the base plate 7 and a processing unit. The output ends of the plurality of jacks 10 are connected to the bottom of the support plate 8.

[0034] Several heat dissipation plates arranged around the reactor body can provide good heat dissipation effect for the reactor body.

[0035] Embodiment 2

[0036] The reactor device of this embodiment is further designed on the basis of the first embodiment, specifically: in this embodiment, a guide portion 42 is provided at the bottom of the upper cover plate 4 corresponding to the heat sink socket 41, and a guide port matching the heat sink socket is provided on the guide portion 42, thereby increasing the depth of the heat sink socket, so that the heat sink will not tilt after being inserted from the heat sink socket of the upper cover plate 4, and can directly fall into the corresponding heat sink socket on the lower cover plate 5, and at the same time, the heat sink socket on the lower cover plate 5 is a blind hole opening upward, and after the heat sink falls into the heat sink socket, it can be supported in the heat sink socket, which is convenient for installation and quick replacement; the length of the heat sink is not less than the distance between the top surface of the upper cover plate 4 and the bottom surface of the lower cover plate 5; a number of heat sink fins are provided on the surface of the heat sink, and these fins can increase the heat dissipation area and improve the heat dissipation efficiency. The shape, size and number of the fins can be optimized and designed according to specific heat dissipation requirements to further improve the heat dissipation effect.

[0037] The heat sink is a ceramic heat sink, and its components include 70% to 90% by weight of aluminum oxide and 10% to 15% by weight of silicon dioxide. Aluminum oxide has excellent thermal conductivity, thermal stability and high insulation, and is an ideal material for making heat sinks; the addition of silicon dioxide can adjust the thermal expansion coefficient and mechanical strength of the ceramic material, and enhance the stability and durability of the heat sink.

[0038] Ceramic heat sinks can be customized according to the size, power and other parameters of the inductor to ensure the best heat dissipation effect. Customized specifications include the size of the heat sink, the shape and layout of the heat sink fins, etc. The ceramic heat sink has high thermal conductivity and can quickly transfer the heat generated by the inductor to the heat sink fins, and dissipate the heat to the surrounding environment through air convection and other methods. At the same time, the ceramic heat sink has good insulation properties and can effectively isolate the electrical connection between the inductor and other circuit components to ensure the safe operation of the circuit. The ceramic heat sink is made of natural organic materials, meets environmental protection requirements, and will not pollute the environment. The ceramic heat sink has the characteristics of high temperature resistance, wear resistance, oxidation resistance, acid and alkali resistance, etc. It can work stably for a long time in harsh working environments and has a long service life.

[0039] In this embodiment, the reactor body includes a plurality of coils 1 arranged side by side, iron yokes 2 arranged at both ends of the coils and a clamping plate 3 for clamping the iron yokes, wherein the clamping plate 3 includes an upper clamping plate and a lower clamping plate for clamping the upper and lower iron yokes 2 respectively, the upper clamping plate includes two pieces symmetrically arranged on both sides of the upper iron yoke, the two upper clamping plates are fixed by bolts to ensure the clamping of the upper iron yoke, the lower clamping plate has the same structure as the upper clamping plate and will not be described in detail, the lower clamping plate is symmetrically arranged with the upper clamping plate, and the two can be further connected and fixed by bolts so that the upper and lower iron yokes 2 are fixed to the two ends of the coil 1; the outer wall of the coil 1 is affixed with insulating stays (not shown in the figure) every 45 degrees along the circumferential direction to increase the strength of the coil.

[0040] The upper cover plate 4 is welded to the upper clamping plate, and the lower cover plate 5 is welded to the lower clamping plate. At least the middle of the upper cover plate 4 is provided with a notch to expose the upper iron yoke, so as to facilitate the heat dissipation of the reactor body. Figure 3 shown.

[0041] In this embodiment, a seismic isolation resin is placed between the iron yoke 2 and the coil 1 to provide a certain thermal conductivity and high impact resistance, further improving the heat dissipation and seismic isolation capabilities.

[0042] Embodiment 3

[0043] The reactor device of this embodiment is further designed on the basis of the first embodiment, specifically: Figure 4 As shown, the laminated rubber damping layer 11 in the seismic isolation bearing is composed of 5 mm thick steel plates and rubber alternately stacked, and the top and bottom layers are both steel plates, which are used to be fixedly connected to the upper lower cover plate 5 and the lower support plate 8. The outer periphery of the laminated rubber damping layer 11 can be wrapped with rubber to enhance the seismic isolation performance of the laminated rubber damping layer 11.

[0044] A plurality of springs 9 are provided in the middle between the bottom plate 7 and the support plate 8, and both ends of the springs 9 are connected to the bottom plate 7 and the support plate 8 respectively, so as to provide support and have a certain seismic isolation effect.

[0045] The vibration sensors of the active seismic isolation module (not shown in the figure), such as accelerometers, displacement sensors, etc., are installed at key positions of the structure to be protected and are used to detect the vibration of the structure in real time. The upper cover plate 4 and the lower cover plate 5 of this embodiment are both rectangular, so the vibration sensors are respectively arranged at the four corners of the upper and lower cover plates. This embodiment is provided with four jacks 21, which are respectively arranged at the four corners of the base plate 7; the vibration sensor and the jack work together to achieve the stability and safety of the structure.

[0046] The processing unit receives the signal from the vibration sensor and converts it into digital data for subsequent analysis and processing. It then analyzes the collected vibration data and extracts the characteristic parameters of the structural vibration, such as amplitude and frequency. By analyzing these parameters, the vibration state of the structure can be determined and its future vibration trend can be predicted. According to the results of the vibration analysis, the isolation control logic will generate a corresponding control signal to adjust the working state of the hydraulic jack through the active isolation actuator. For example, when it is detected that the structure is about to vibrate significantly, the control logic will instruct the hydraulic jack to generate a corresponding force to offset the impact of the vibration on the structure, thereby protecting the safety of the structure.

[0047] like Figure 5 As shown, it is a schematic diagram of the processing module, and the processing process of the processing module is:

[0048] The processing unit first filters the received vibration signal to remove noise and interference signals to ensure the accuracy of the vibration information.

[0049] Module A is the functional state and module B is the module input.

[0050] 1) The judgment logic of module A is as follows: ① The failure probability y of the device corresponding to the input IM (ground motion intensity index) is calculated according to the CDF vulnerability curve of the device; ② The characteristic value signal r of the vibration sensor is compared; ③ The equipment vulnerability module determines the size relationship between r and y. If r≥y, the device is judged to be open and the output result is "1"; if r<y, the device is judged to be disconnected and the output result is "0".

[0051] 2) The judgment logic of module B is as follows: ① Collect, filter and process the characteristic value signal R of the vibration sensor; ② Inherit the state of the previous stage ("1" or "0"); ③ The output result of the module is determined by the numerical value of R and the state of the previous stage, and the more dangerous value between the two is input into the Switch module; ④ If the input value is greater than 0.5 (the median value of equipment vulnerability), output "1"; otherwise, output "0".

[0052] The output result of the system is jointly determined by modules A and B. When the output is "1" at the same time, it is confirmed that an earthquake has occurred and a signal is sent to the intelligent seismic isolation module.

[0053] 3) PID control is used to generate corresponding control signals based on the vibration characteristics extracted by the processing unit. These control signals will be directly related to the action of the jack to adjust the position and posture of the structure. Under the action of external forces such as earthquakes, the jack can quickly respond to the control signal and generate sufficient force to offset the impact of vibration on the structure, thereby maintaining the stability and safety of the structure and achieving effective suppression of vibration.

[0054] The technical solutions of the present invention are not limited to the above-mentioned embodiments, and any technical solutions obtained by equivalent replacement methods fall within the scope of protection required by the present invention.
