Description
Technical Field
[0001] This invention relates to the field of power equipment technology, and in particular to an anti-interference device for intelligent switchgear. Background Technology
[0002] A switchgear is an electrical device whose main function is to open, close, control, and protect electrical equipment during the power generation, transmission, distribution, and energy conversion processes in a power system. Switchgear contains various electrical devices such as circuit breakers, disconnect switches, load switches, operating mechanisms, instrument transformers, and various protective devices. In daily use, external electromagnetic interference can affect the operation of the internal electrical equipment, potentially causing malfunctions. Therefore, existing switchgear incorporates anti-interference measures. Common anti-interference measures include metal shielding and grounding. Metal shielding refers to a layer of metal mesh installed on the side wall or outside of the switchgear. This mesh shields external electromagnetic signals, preventing them from entering the switchgear. Grounding, since most switchgear is made of metal, prevents electromagnetic wave intrusion, thus providing anti-interference protection.
[0003] For anti-interference measures using metal shielding mesh, the metal shielding mesh is mostly fixedly installed inside the switch cabinet and cannot be moved. During long-term use, due to corrosion of the switch cabinet material or improper installation of the metal shielding mesh, some parts of the metal shielding mesh may be damaged, resulting in ineffective shielding of electromagnetic waves. Electromagnetic waves can easily enter the switch cabinet from the damaged parts of the metal shielding mesh, causing damage to the internal electrical equipment. In this case, it is often necessary to replace the entire switch cabinet, which greatly increases the operating cost. Summary of the Invention

[0010] Preferably, the side wall of the cylindrical metal mesh cover is provided with an opening fan, which is connected to the cylindrical metal mesh cover by a hinge.

Detailed Implementation
[0025] To better understand the technical content of this invention, a specific embodiment is provided below, and the invention will be further described in conjunction with the accompanying drawings.
[0026] See Figures 1 to 4This invention provides an intelligent switch cabinet anti-interference device, comprising a switch cabinet body 1, a cylindrical metal mesh cover 2, a base plate 3, an orientation adjustment mechanism, an anti-interference capability detection mechanism, and a main control unit 4. The switch cabinet body 1 is mounted on the base plate 3. The orientation adjustment mechanism includes a rotary motor 5, a rotating ring 6, a rack 7, and a gear 8. The rotating ring 6 is rotatably mounted on the base plate 3. The bottom end of the cylindrical metal mesh cover 2 is connected to the top surface of the rotating ring 6 and covers the outside of the switch cabinet body 1. The rack 7 is circumferentially mounted on the outer wall of the rotating ring 6. The rotary motor 5 is embedded in the base plate 3, and its output shaft is connected to the gear 8, which meshes with the rack 7. The anti-interference capability detection mechanism includes a dual-axis motor 9, an inner rotating rod 10, an internal electromagnetic wave sensor 11, an outer rotating rod 12, a vertical rod 13, an external electromagnetic wave sensor 14, and an electromagnetic wave generator 15. 9 is located in the middle of the top surface of the switch cabinet 1, and its lower output shaft extends into the interior of the switch cabinet 1 to drive the inner rotating rod 10 to rotate inside the switch cabinet 1. The internal electromagnetic wave sensor 11 is located at one end of the inner rotating rod 10. The upper output shaft of the dual-axis motor 9 extends above the cylindrical metal mesh cover 2 and is connected to one end of the outer rotating rod 12. The top end of the vertical rod 13 is connected to the bottom surface of the rotating rod, and its bottom end is slidably connected to the top surface of the base plate 3. The electromagnetic wave generator 15 and the external electromagnetic wave sensor 14 are located on different side walls of the vertical rod 13 and are arranged opposite to each other. The external electromagnetic wave sensor 14 is located between the electromagnetic wave generator 15 and the internal electromagnetic wave sensor 11. The main control unit 4 is located on the inner side wall of the switch cabinet 1 and is electrically connected to the rotary motor 5, the internal electromagnetic wave sensor 11, the external electromagnetic wave sensor 14 and the electromagnetic wave generator 15 respectively.
[0027] The switch cabinet 1 is used to install various power switches and other power components. It is located above the base plate 3, which can be embedded in the soil. The switch cabinet 1 is covered by a cylindrical metal mesh cover 2. When external electromagnetic wave signals are transmitted to the cylindrical metal mesh cover 2, they will be shielded by the cylindrical metal mesh cover 2, which prevents electromagnetic wave signals from entering the switch cabinet 1 and causing accidental contact or damage to the internal components. With the setting of the cylindrical metal mesh cover 2, the cylindrical metal mesh cover 2 can be replaced regularly, or replaced in time when the cylindrical metal mesh cover 2 is damaged, reducing the cost of use and the workload of the staff.
[0028] During long-term use, the outer wall of the cylindrical metal mesh cover 2 may be damaged to varying degrees due to weather or external forces, resulting in different electromagnetic interference resistance in different areas. To address this, a rotating ring 6 is installed on the bottom surface of the cylindrical metal mesh cover 2. The rotary motor 5 embedded in the base plate 3 can drive the gear 8 to rotate. The gear 8 can drive the rotating ring 6 to rotate on the base plate 3 through the rack 7 on the outer wall of the rotating ring 6, thereby realizing the rotation of the entire cylindrical metal mesh cover 2. This allows the area with stronger anti-interference ability to be rotated to the position of the switch cabinet 1 that is more susceptible to electromagnetic radiation, thus ensuring the normal operation of the internal components of the switch cabinet 1.
[0029] For switch cabinet 1, most of the electromagnetic radiation it receives is generated by external equipment. Since most of the equipment that generates electromagnetic radiation is large and difficult to move, the direction and intensity of the electromagnetic radiation received by switch cabinet 1 remain relatively fixed over a long period of time. Therefore, an external electromagnetic wave sensor 14 is installed outside switch cabinet 1. The external electromagnetic wave sensor 14 can detect external electromagnetic radiation. Driven by the dual-axis motor 9, the external electromagnetic wave sensor 14 rotates around the cylindrical metal mesh cover 2 via the external rotating rod 12 and the vertical rod 13. This allows the detection of electromagnetic wave intensity at different locations outside switch cabinet 1, ultimately determining the location where switch cabinet 1 receives the strongest electromagnetic radiation. This enables the area of the cylindrical metal mesh cover 2 with the strongest anti-interference capability to be moved to the location with the strongest electromagnetic radiation intensity, thereby achieving efficient electromagnetic shielding.
[0030] To determine the area with the strongest anti-interference capability of the cylindrical metal mesh cover 2, this invention includes an internal electromagnetic wave sensor 11 inside the switch cabinet 1 and an electromagnetic wave generator 15 outside the external electromagnetic wave sensor 14. The electromagnetic wave generator 15 generates electromagnetic wave signals and sends them towards the switch cabinet 1. The electromagnetic wave signals pass sequentially through the external electromagnetic wave sensor 14, the cylindrical metal mesh cover 2, the switch cabinet 1, and the internal electromagnetic wave sensor 11. The degree to which the electromagnetic waves are shielded by the cylindrical metal mesh cover 2 can be detected by the internal and external electromagnetic wave sensors, thereby determining the shielding capability of the cylindrical metal mesh cover 2. The electromagnetic shielding capability of the mesh cover 2 is achieved by the upper output shaft of the dual-axis motor 9 installed at the top of the switch cabinet 1, which can drive the external electromagnetic wave sensor 14 and electromagnetic wave generator 15 to rotate via the external rotating rod 12 and the vertical rod 13. During the rotation, the anti-interference capability of all areas of the cylindrical metal mesh cover 2 can be detected to obtain the area with the strongest anti-interference capability. The upper output shaft of the dual-axis motor 9 passes directly through the cylindrical metal mesh cover 2 and is not connected to it. The output shaft of the dual-axis motor 9 will not drive the cylindrical metal mesh cover 2 to rotate.
[0031] Preferably, the anti-interference capability detection mechanism further includes a lifting mechanism, which includes an electric push rod 16, a lifting plate 17, and an electric slide 18. The top surface of the electric push rod 16 is connected to the output shaft at the lower end of the dual-axis motor 9, and its output shaft is connected to the top surface of the lifting plate 17. The inner rotating rod 10 is disposed on the bottom surface of the lifting plate 17. The electric slide 18 is disposed on the side wall of the vertical rod 13. The external electromagnetic wave sensor 14 and the electromagnetic wave generator 15 are disposed on the movers 19 of different electric slides 18. The main control unit 4 is electrically connected to the electric push rod 16 and the electric slide 18 respectively.
[0032] For the cylindrical metal mesh cover 2, which has a certain height, when testing its anti-interference capability, since the electromagnetic wave generated by the electromagnetic wave generator 15 has a limited transmission area, the internal electromagnetic wave sensor 11, the external electromagnetic wave sensor 14, and the electromagnetic wave generator 15 need to be set to be height-adjustable. The electric push rod 16 can drive the inner rotating rod 10 to rise and fall through the lifting plate 17 to adjust the height of the internal electromagnetic wave sensor 11. The electric slide table 18 set on the vertical rod 13 can drive the external electromagnetic wave sensor 14 and the electromagnetic wave generator 15 to rise and fall, so that the three are kept at the same height, so as to test the anti-interference capability of the cylindrical metal mesh cover 2 at different heights.
[0033] Preferably, the top surface of the base plate 3 is provided with a plurality of concentric annular grooves 20, and the bottom surface of the rotating ring 6 is provided with a slide bar 21, wherein the slide bar 21 and the bottom end of the vertical rod 13 are located in different concentric annular grooves 20.
[0034] When the rotary motor 5 drives the rotating ring 6 to rotate, the slide bar 21 on the bottom surface of the rotating ring 6 will move along the concentric ring groove 20 to prevent the rotation from deviating. At the same time, when the upper output shaft of the dual-axis motor 9 drives the outer rotating rod 12 to rotate, the bottom ends of the two vertical rods 13 can rotate along different concentric ring grooves 20 to realize the position adjustment of the external electromagnetic wave sensor 14 and the electromagnetic wave generator 15.
[0035] Preferably, the anti-interference capability testing mechanism further includes an inclined support rod 22, one end of which is connected to the housing of the dual-axis motor 9, and the other end is connected to the top surface of the switch cabinet 1.
[0036] The inclined support rod 22 is used to connect and fix the dual-axis motor 9.
[0037] Preferably, the cylindrical metal mesh cover 2 is provided with an opening fan 23 on its side wall, and the opening fan 23 is connected to the cylindrical metal mesh cover 2 via a hinge 24.
[0038] The cylindrical metal mesh cover 2 can be opened by opening fan 23, allowing staff to enter the interior of the cylindrical metal mesh cover 2 to operate the switch cabinet 1.
[0039] Preferably, it also includes an obstruction detection mechanism, which includes a reflective strip 25, a transmitting tube 26, and a receiving tube 27. The reflective strip 25 is disposed on the outer wall of the opening fan 23. The transmitting tube 26 and the receiving tube 27 are symmetrically disposed on the side wall of the vertical rod 13. The reflective strip 25 is located on one side of the rotation path of the transmitting tube 26 and the receiving tube 27. The transmitting tube 26 and the receiving tube 27 are both inclined towards each other. The main control unit 4 is electrically connected to the transmitting tube 26 and the receiving tube 27 respectively.
[0040] To prevent the opening fan 23 from failing to open when it is located on one side of the vertical rod 13, a reflective strip 25 is provided on the outer wall of the opening fan 23. A transmitter 26 and a receiver 27 are provided on the side wall of the vertical rod 13 near the cylindrical metal mesh cover 2. The transmitter 26 and the receiver 27 are set at relative inclination and at the same height as the reflective strip 25. When the reflective strip 25 is located on one side of the transmitter 26 and the receiver 27, the infrared light emitted by the transmitter 26 can be reflected by the reflective strip 25 and received by the receiver 27. The receiver 27 can generate a signal and send it to the main control unit 4. The main control unit 4 determines that the opening fan 23 is located on one side of the vertical rod 13. At this time, the dual-axis motor 9 can drive the vertical rod 13 to rotate, so that the transmitter 26 and the receiver 27 move away from the side of the reflective strip 25, ensuring that the opening fan 23 can be opened normally.
[0041] Preferably, the anti-interference capability detection mechanism further includes a lidar 28, which is mounted on the mover 19 of the electric slide 18 where the electromagnetic wave generator 15 is located. The main control unit 4 includes a shielding value calculation unit 29, a height calculation unit 30, a weighting unit 31, and a shielding value accumulation unit 32. The shielding value calculation unit 29 is connected to the internal electromagnetic wave sensor 11 and the external electromagnetic wave sensor 14, respectively. The lidar 28 is connected to the height calculation unit 30, and the weighting unit 31 is connected to the height calculation unit 30, the shielding value calculation unit 29, and the shielding value accumulation unit 32, respectively.
[0042] The electromagnetic wave intensity information collected by the external electromagnetic wave sensor 14 and the internal electromagnetic wave sensor 11 can be transmitted to the shielding value calculation unit 29. The shielding value calculation unit 29 can calculate the shielding value based on the difference between the internal electromagnetic wave intensity data.
[0043] The electrical equipment inside the switch cabinet 1 is located at different heights, and different types of electrical equipment have different resistance to electromagnetic waves. Therefore, the requirements for the shielding effect of electromagnetic waves are also different. The weighting unit 31 assigns different weights to the shielding values of different types of electrical equipment. Therefore, when calculating the shielding value, it is also necessary to obtain the height of the electromagnetic wave generator 15 at the same time in order to obtain the type of electrical equipment. Then, the weighting unit 31 can assign weights according to the electrical equipment. Finally, the weighted shielding value can be accumulated in the shielding value accumulation unit 32 to obtain the anti-interference capability of the cylindrical metal mesh cover 2 facing the same direction.
[0044] To facilitate height calculation, a lidar 28 is installed on the mover 19 of the electric slide table 18. The lidar 28 can emit signals downwards and receive reflected signals. The height calculation unit 30 can calculate the height of the electromagnetic wave generator 15 based on the signals emitted and received by the lidar 28, and send the height information to the weighting unit 31. The weighting unit 31 can then assign weights based on the height information and the type of electrical equipment.
[0045] Preferably, the main control unit 4 further includes a weight update unit 33, which is data-connected to the weighting unit 31 and is used to provide different weights to the weighting unit 31 according to the types of electrical equipment at different heights inside the switch cabinet 1.
[0046] For different switch cabinets 1, the arrangement of the electrical equipment inside is different and the height is different. After knowing the height of each type of electrical equipment inside the switch cabinet in advance, the type of electrical equipment and the corresponding height are transmitted to the weight update unit 33. The weight update unit 33 can update the weight. The weighting unit 31 can assign different weights when the electromagnetic wave generator 15 is at different heights.
[0047] Preferably, it also includes a grounding rod 34, the top end of which is connected to the bottom surface of the switch cabinet 1, and its bottom end passes through the bottom plate 3 and extends into the soil below the bottom plate 3.
[0048] The grounding rod 34 can effectively ground the switch cabinet 1, further improving the anti-interference capability of the switch cabinet 1.
[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
