Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power equipment safety maintenance, and particularly relates to a method for preventing resonance of a shielding net in a control room of a transformer substation and a resonance-preventing assembly of the shielding net. BACKGROUND

[0002] Due to the special nature of power consumption of power grid projects, shielding windows are usually arranged in the control room of a transformer substation to shield the electric field, magnetic field or electromagnetic wave outside the control room from affecting the equipment inside the control room.

[0003] The shielding window comprises a window frame and a glass plate. The shielding window comprises four window frame bodies connected end to end. Two of the window frame bodies are oppositely arranged and extend in the vertical direction, and the other two window frame bodies are oppositely arranged and extend in the horizontal direction. The glass plate comprises two glass bodies and a shielding net. The two glass bodies are both cuboid structures. The two glass bodies are arranged on opposite sides of the shielding net, respectively. The four sides of the glass body are fixed to the sides of the four window frame bodies in the thickness direction, respectively. The glass body provides protection for the shielding net. The shielding net is fixed to the two window frame bodies extending in the vertical direction through welding points on opposite sides of the shielding net in the horizontal direction. The shielding net is fixed to the window frame body through at least two welding points on the same side of the shielding net in the horizontal direction. Due to the large size of the shielding net, in order to ensure the assembly efficiency of the shielding net and the window frame, a welding point is arranged on the shielding net at an interval to connect the window frame body. The two adjacent welding points on the same window frame body are arranged at an interval along the extension direction of the window frame body. However, due to the connection mode of the shielding net and the window frame body, there is a certain gap between the two adjacent welding points in the vertical direction, so that the area between the two adjacent welding points of the shielding net in the vertical direction is not fixed to the window frame body. When the equipment (such as electrical equipment or air conditioner) in the control room is running, there is a large noise, which resonates with the shielding net and produces a huge noise, affecting the working environment in the control room. In addition, the resonance of the shielding net also causes the shielding net to loosen on the window frame body. SUMMARY

[0004] The present application aims to provide a method for preventing resonance of a shielding net in a control room of a transformer substation and a resonance-preventing assembly, which can prevent the resonance of the shielding net and the equipment in the control room.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical solutions:

[0006] In one aspect, a method for anti-resonance of a substation control room shielding net is provided. The method includes the following steps:

[0007] In step S10, a position of resonance of the shielding net is detected.

[0008] In step S20, the counterweight is slid on the first slide rail to the position of resonance, and the mass of the shielding net at the position of resonance is increased by the counterweight.

[0009] In one preferred technical solution of the method for anti-resonance of a substation control room shielding net, in step S10, a resonance detection component is used to detect the position of resonance of the shielding net.

[0010] In one preferred technical solution of the method for anti-resonance of a substation control room shielding net, in step S20, a driving member is used to drive the counterweight to slide on the first slide rail.

[0011] In one preferred technical solution of the method for anti-resonance of a substation control room shielding net, when the resonance detection component detects resonance on the shielding net, it is determined whether the position of the counterweight is at the same position as the resonance detection component on the shielding net. If not, the driving member drives the counterweight to move to the position of the resonance detection component. If yes, the driving member drives the counterweight to move away from the position of the resonance detection component.

[0012] In another aspect, an anti-resonance component is provided. The anti-resonance component is applied to the method for anti-resonance of a substation control room shielding net. The anti-resonance component is arranged between two adjacent welding points in the vertical direction of the shielding net. The anti-resonance component includes a first slide rail, a driving member, and a counterweight slidably arranged on the first slide rail. The length of the first slide rail extends in the horizontal direction. The moving end of the driving member is connected with the counterweight, and is used to drive the counterweight to slide on the first slide rail.

[0013] As a preferred technical scheme of the anti-resonance assembly, the anti-resonance assembly further comprises a master controller and at least two resonance detection components, all of the resonance detection components are distributed along a horizontal direction, the resonance detection components are capable of detecting whether the shielding net resonates, the master controller is respectively connected with the driving member and each of the resonance detection components in communication, when the resonance detection component resonates with the shielding net, the master controller is capable of controlling the driving member to drive the counterweight to move to a position where the resonance detection component is located.

[0014] As a preferred technical scheme of the anti-resonance assembly, the driving member comprises a driving motor and a second sliding rail, the second sliding rail and the first sliding rail are respectively distributed along a vertical direction, and a length direction of the second sliding rail is parallel to a length direction of the first sliding rail, an output shaft of the driving motor is connected with the counterweight through a connecting arm, the connecting arm is provided with a threaded hole penetratingly, the output shaft is provided with a threaded section, the threaded section extends along the length direction of the output shaft, the threaded section on the output shaft is connected with the threaded hole in a matched mode, and the connecting arm is connected with the second sliding rail in a sliding mode through a sliding block.

[0015] As a preferred technical scheme of the anti-resonance assembly, the first sliding rail and the second sliding rail are distributed in a spaced mode.

[0016] As a preferred technical scheme of the anti-resonance assembly, the driving motor further comprises a motor body, one end of the output shaft is connected with the motor body, a limiting protrusion is protruded on the output shaft, the limiting protrusion is located on a side of the output shaft which is away from the motor body, and the limiting protrusion is used for blocking the connecting arm from falling off from the end which is away from the motor body.

[0017] As a preferred technical scheme of the anti-resonance assembly, the master controller is connected with the driving motor and each of the resonance detection components in communication through a communication cable.

[0018] The anti-resonance assembly has the following advantages: in the scheme, when the shielding net resonates at a certain position between two adjacent welding points in the vertical direction, the counterweight is slid to the position, the weight of the shielding net at the position is increased through the counterweight, so that the natural frequency of the shielding net at the position is changed, the natural frequency of the shielding net at the position is different from the vibration frequency of the noise in the control room, so that the shielding net is prevented from resonating at the position, the local resonance of the shielding net is prevented from increasing the noise in the control room, and the shielding net is prevented from loosening in the window frame due to the resonance.

[0028] As shown in Figs. 1-3 The present application provides a method for preventing resonance of a substation control room shielding net, which comprises a resonance prevention assembly. The shielding window comprises a window frame 1 and a glass plate. The shielding window comprises four window frame bodies 11 connected end to end. Two of the window frame bodies 11 are oppositely arranged and vertically arranged. The other two window frame bodies 11 are oppositely arranged and horizontally arranged. The glass plate comprises two glass bodies and a shielding net 3. The two glass bodies are cuboid structures and are arranged on opposite sides of the shielding net 3. The resonance prevention assembly is arranged between the glass body and the shielding net 3. The four sides of the shielding net 3 are fixed to the side surfaces of the window frame body 11 in the thickness direction by welding points 2. The glass body provides a protective effect for the shielding net 3. Specifically, the shielding net 3 has a first side and a second side in the horizontal direction. The first side is opposite to the second side. The first side and the second side of the shielding net are fixed to the two window frame bodies 11 arranged in the vertical direction by welding points 2. In this example, the first side and the second side of the shielding net 3 are fixed to the same window frame body 11 arranged in the vertical direction by three welding points 2. The three welding points 2 are arranged in the vertical direction.

[0029] The resonance prevention assembly is arranged between the two welding points 2 arranged in the vertical direction on the shielding net 3. The resonance prevention assembly comprises a first sliding rail 4 and a counterweight 8. The first sliding rail 4 is fixed to the shielding net 3. The counterweight 8 is slidingly arranged on the first sliding rail 4. The length of the first sliding rail 4 extends in the horizontal direction. The method comprises the following steps:

[0030] Step S10: detecting the resonance position of the shielding net 3 between the two welding points 2 arranged in the vertical direction. The resonance position is obtained on the shielding net 3.

[0031] Step S20: sliding the counterweight 8 on the first sliding rail 4 to the resonance position. The mass of the shielding net 3 at the resonance position is increased by the counterweight 8.

[0032] It can be understood that the inside of the control room of the transformer substation is provided with a plurality of devices, such as electrical devices or air conditioners, etc., and the devices generate a large noise when working, and the lateral stiffness of the shielding net 3 is smaller in the area between two welding points 2 adjacent in the vertical direction of the shielding net 3, and the mass of the shielding net 3 is the same everywhere, according to ω=(k / m)^(1 / 2) (where ω refers to the vibration frequency inherent to the elastic system itself, k is the lateral stiffness of the elastic system, and m is the mass of the elastic system), the lateral stiffness of each part of the shielding net 3 is different along the horizontal direction in the area between two welding points 2 adjacent in the vertical direction of the shielding net 3, and the inherent frequency of the shielding net 3 corresponding to each part is different under the condition that the mass of each part of the shielding net is the same, so that the local resonance phenomenon of the shielding net 3 exists in the area between two welding points 2 adjacent in the vertical direction along the horizontal direction, that is, the phenomenon that resonance occurs in one part and does not occur in another part of the area between two welding points 2 adjacent in the vertical direction of the shielding net 3 along the horizontal direction.

[0033] In the present application, when resonance occurs in a part of the area between two welding points 2 adjacent in the vertical direction of the shielding net 3 under the influence of the noise of the devices in the control room, the counterweight 8 is slid to the part, the weight of the shielding net 3 at the part is increased through the counterweight 8, so as to change the inherent frequency of the shielding net 3 at the part, so that the inherent frequency of the shielding net 3 at the part is different from the vibration frequency of the noise in the control room, thereby preventing resonance of the shielding net 3 at the part, preventing the local resonance of the shielding net 3 from increasing the noise in the control room, and preventing the shielding net 3 from loosening in the window frame 1 due to resonance.

[0034] In step S10, the part of the shielding net 3 where resonance occurs is detected by using the resonance detection component 9. When the inherent frequency of the shielding net 3 at the part where the resonance detection component 9 is located is the same as the vibration frequency detected by the resonance detection component 9, it indicates that resonance occurs in the shielding net 3 at the part.

[0035] In the present embodiment, in step S20, the counterweight 8 is driven to slide on the first sliding rail 4 by the driving member, so as to move the counterweight 8. In other examples, the counterweight 8 can also be manually driven to slide on the first sliding rail 4.

[0036] Preferably, when the resonance detecting component 9 detects resonance on the shielding net 3, it is first determined whether the position of the counterweight 8 is at the same position as the resonance detecting component 9 on the shielding net 3, and when the position of the counterweight 8 is not at the same position as the resonance detecting component 9 on the shielding net 3, the driving member drives the counterweight 8 to move to the position of the resonance detecting component 9, and vice versa. When the resonance detecting component 9 detects resonance on the shielding net 3, it indicates that the shielding net 3 resonates at the position of the resonance detecting component 9, and thus the counterweight 8 needs to be moved to the position of the resonance detecting component 9.

[0037] In actual implementation, in the anti-resonance method of the shielding net 3 of the transformer substation control room, at least two resonance detecting components 9 are arranged between two adjacent welding points 2 of the shielding net 3 in the vertical direction, and all the resonance detecting components 9 in the same anti-resonance assembly are spaced apart along the horizontal direction. The counterweight 8 has an initial position, and the initial position is close to the first side of the shielding net 3. Each resonance detecting component 9 is provided with a position sensor, which can transmit the position information of the corresponding resonance detecting component 9 to the main controller. When there is a resonance position on the shielding net 3, the driving member drives the counterweight 8 to move to the initial position.

[0038] In this embodiment, referring to Figs. 1-3 , an anti-resonance assembly is provided for the anti-resonance method of the shielding net 3 of the transformer substation control room. The anti-resonance assembly is arranged in the region between two adjacent welding points 2 of the shielding net 3 in the vertical direction, and the anti-resonance assembly comprises a first sliding rail 4, a driving member, and a counterweight 8 slidingly arranged on the first sliding rail 4. The first sliding rail 4 extends along the horizontal direction, and in this example, one end of the first sliding rail 4 extends from the first side of the shielding net 3 to the second side. The moving end of the driving member is connected with the counterweight 8, and is used to drive the counterweight 8 to move on the first sliding rail 4. The first sliding rail 4 is fixed on the shielding net 3, and the counterweight 8 slides along the length direction of the first sliding rail 4, so as to change the mass of each position of the shielding net 3 in the horizontal direction. The anti-resonance assembly with this structure guides and slides the counterweight 8 through the first sliding rail 4, and drives the counterweight 8 to move on the first sliding rail 4 under the driving of the driving member, so that the counterweight 8 changes the mass of each position of the shielding net 3 in the horizontal direction. When the shielding net 3 resonates at a position in the region between two adjacent welding points 2 in the vertical direction, the counterweight 8 is slid to the position, and the weight of the shielding net 3 at the position is increased through the counterweight 8, so as to change the natural frequency of the shielding net 3 at the position. Thus, the natural frequency of the shielding net 3 at the position is different from the vibration frequency of the noise in the control room, so as to prevent the shielding net 3 from resonating at the position, prevent the local resonance of the shielding net 3 from increasing the noise in the control room, and prevent the shielding net 3 from loosening in the window frame 1 due to resonance.

[0039] In actual implementation, the anti-resonance component is arranged between every two adjacent welding points in the vertical direction on the shielding net 3, Fig. 3 In the figure, only two anti-resonance components arranged between every two adjacent welding points in the vertical direction on the shielding net 3 are shown.

[0040] The anti-resonance component further comprises a main controller (not shown in the figure) and at least two resonance detection components 9. All resonance detection components 9 in the same anti-resonance component are spaced apart along the horizontal direction. The resonance detection components 9 can detect whether the shielding net 3 resonates. The main controller is in communication connection with the driving member and each resonance detection component 9. When the resonance detection component 9 resonates with the shielding net 3, the main controller can control the driving member to drive the counterweight 8 to move to the position of the resonance detection component 9. By arranging the main controller, the counterweight 8 can be automatically moved to the resonance position, facilitating the movement of the counterweight 8.

[0041] Specifically, the driving member comprises a driving motor 5 and a second sliding rail 6. The second sliding rail 6 and the first sliding rail 4 are arranged along the vertical direction respectively. The length direction of the second sliding rail 6 is parallel to the length direction of the first sliding rail 4. The output shaft 52 of the driving motor 5 is connected with the counterweight 8 through a connecting arm 7. The connecting arm 7 is provided with a threaded hole penetratingly. The output shaft 52 is provided with a threaded section extending along the length direction of the output shaft 52. The threaded section on the output shaft 52 is connected with the threaded hole in a threaded manner. The connecting arm 7 is connected with the second sliding rail 6 in a sliding manner through a sliding block. The output shaft 52 penetrates the threaded hole and is screwed in the threaded hole. The driving motor 5 can be mounted on the shielding net 3 or mounted on the window frame 1 through a mounting bracket, without limitation on the specific mounting position of the driving motor 5. When the output shaft 52 of the driving motor 5 rotates, the connecting arm 7 is driven to move along the length direction of the output shaft 52, and then the counterweight 8 is driven to slide on the first sliding rail 4. The second sliding rail 6 provides guidance for the movement of the connecting arm 7.

[0042] In order to prevent interference between the second sliding rail 6 and the first sliding rail 4, the first sliding rail 4 and the second sliding rail 6 are spaced apart.

[0043] The driving motor 5 further comprises a motor body 51. One end of the output shaft 52 is connected with the motor body 51. The output shaft 52 is provided with a limiting protrusion 53 protruding therefrom. The limiting protrusion 53 is located on the side of the output shaft 52 away from the motor body 51. The limiting protrusion 53 is used to block the connecting arm 7 from falling off from the end away from the motor body 51. By limiting the connecting arm 7 through the limiting protrusion 53, the connecting arm 7 can be effectively prevented from falling off from the output shaft 52.

[0044] In this example, the main controller is in communication connection with the driving motor 5 and each resonance detection component 9 through a communication cable, realizing signal transmission of the main controller and the driving motor 5.

[0045] Specifically, the counterweight 8 is provided with a position sensor (not shown in the figure) for detecting the position of the counterweight 8, which is in communication connection with the master controller. Taking the example of three resonance detection components 9 provided in the same anti-resonance assembly, the anti-resonance method of the substation control room shielding net 3 is described in detail. From the first side of the shielding net 3 to the second side, the three resonance detection components 9 are in turn the first resonance detection component 91, the second resonance detection component 92 and the third resonance detection component 93, and the positions of the shielding net 3 where the first resonance detection component 91, the second resonance detection component 92 and the third resonance detection component 93 are located are in turn the first position 31, the second position 32 and the third position 33, and the first sliding rail 4 extends from the first position 31 to the third position 33. The positions of the first resonance detection component 91, the second resonance detection component 92 and the third resonance detection component 93 on the shielding net 3 are respectively stored in the master controller. When the first resonance detection component 9 detects the resonance of the shielding net 3, the position sensor transmits the position information of the counterweight 8 to the master controller, and the master controller compares the received position information of the counterweight 8 with the position information of the first resonance detection component 9 to determine whether the position of the counterweight 8 and the position of the first resonance detection component 91 are in the same position (i.e. whether the counterweight 8 is located in the first position 31). When the position of the counterweight 8 and the position of the first resonance detection component 91 are not in the same position (i.e. when the counterweight 8 is not in the first position 31), the master controller controls the output shaft 52 of the driving motor 5 to move the counterweight 8 to the position where the first resonance detection component 91 is located. Conversely (i.e. the counterweight 8 is in the first position 31), the output shaft 52 of the driving motor 5 drives the counterweight 8 to slide from the first position 31 to the second position 32 or the third position 33. When the second resonance detection component 92 or the third resonance detection component 93 detects the resonance of the shielding net 3, the working process of the anti-resonance assembly is similar to that when the first resonance detection component 91 detects the resonance of the shielding net 3, and will not be described here.
