[0001] The present application relates to the technical field of magnetically controlled reactors, and in particular to a silencing and cooling device for magnetically controlled reactors and a magnetically controlled reactor. Background Art

[0002] Magnetic controlled reactor is a new type of dynamic reactive power compensation device. Due to its low cost, small footprint and maintenance-free, it is increasingly widely used in substations, wind farms, electrified railways, coal mines and other fields. With the rapid advancement of urbanization in my country, urban electricity load is increasing, and the cable rate is getting higher and higher. As a result, grid pollution is becoming increasingly prominent, reactive power demand is increasing, and the fluctuation range is large.

[0003] Since magnetron reactors use the principle of core saturation, the noise is often high. In order to reduce the noise, a common method is to install silencer cotton. However, the continuous operation of magnetron reactors will generate a lot of heat, and the installation of silencer cotton can easily cause poor heat dissipation, making it impossible to achieve both silencer and temperature reduction. Summary of the invention

[0004] In order to improve the noise reduction and temperature reduction effects at the same time, the present application provides a noise reduction and temperature reduction device for a magnetically controlled reactor and a magnetically controlled reactor.

[0005] In the first aspect, the silencing and cooling device of the magnetically controlled reactor provided in the present application adopts the following technical solution: The silencing and cooling device of the magnetically controlled reactor comprises a silencing and cooling mechanism for being arranged on a cabinet, and the silencing and cooling mechanism comprises: A cooling plate is arranged on the inner wall of the cabinet and has a cooling cavity therein and is provided with a plurality of heat sinks that pass through the cabinet and extend to the outside of the cabinet; A cooling component, used for introducing a cooling medium into the cooling chamber for cooling; The sound-absorbing cotton is located between the cooling plate and the inner wall of the cabinet and is used to eliminate noise.

[0006] By adopting the above technical scheme, the cooling component is used to cool the cooling plate, and the heat on the cooling plate can also be dissipated through the heat sink, thereby greatly reducing the temperature of the cooling plate. The cooling plate can well cool the cabinet, and the sound-absorbing cotton can eliminate the noise generated in the cabinet, thereby achieving cooling and silencing at the same time. The silencing of the sound-absorbing cotton will not affect the cooling of the cooling plate, thereby improving the cooling and silencing effects at the same time.

[0007] The speed at which noise propagates in liquid is slower than that in metal, so the speed at which noise propagates will also be slowed down when passing through the cooling medium, allowing the cooling medium to achieve both cooling and silencing effects.

[0008] At the same time, the temperature reduction also causes a pressure difference in the air pressure inside the cabinet. The temperature at the cooling plate is low, that is, the air pressure is low, which makes the hot air inside the cabinet flow towards the cooling plate. Due to the gas flow direction, the noise generated inside the cabinet also moves towards the cooling plate and the sound-absorbing cotton and is eliminated after that, thereby further improving the temperature reduction and sound-absorbing effects.

[0009] Optionally, the cooling component includes: A liquid storage tank, which is arranged on the cabinet body and filled with a cooling medium; A pump body, which is arranged on the liquid storage tank; An inlet pipe and an outlet pipe, which are respectively arranged on the pump body and the liquid storage tank and the other ends of which are both communicated with the cooling cavity. When the pump body starts, the cooling medium is added into the cooling cavity through the inlet pipe and flows back into the liquid storage tank through the outlet pipe.

[0010] By adopting the above technical solution, when the pump body starts, the cooling medium in the liquid storage tank is input into the cooling cavity through the inlet pipe, and then the cooling medium flows back into the liquid storage tank through the outlet pipe, so as to realize the cooling of the cooling plate.

[0011] Optionally, the sound-absorbing cotton is provided with a plurality of insertion holes for inserting and positioning with the heat dissipation fins, and a plurality of elastic components are arranged on the cooling plate and pass through the sound-absorbing cotton and are detachably connected to the cabinet body. The elastic components buffer and damp the cooling plate under the action of elasticity.

[0012] By adopting the above technical solution, the heat dissipation fins are inserted and installed in the sound-absorbing cotton for positioning, so that the sound-absorbing cotton, the heat dissipation fins and the cooling plate can be connected to each other, making the sound-absorbing cotton fit more closely with the heat dissipation fins and the cooling plate, that is, maximizing the area of the sound-absorbing cotton, improving the sound-absorbing effect of the sound-absorbing cotton, and the elastic components can realize the installation of the cooling plate, so that the installation of the sound-absorbing cotton, the heat dissipation fins and the cooling plate can be realized. The elastic components can buffer the cooling plate, reducing the probability that the vibration of the cabinet body drives the cooling plate to vibrate, improving the stability of the cooling plate during temperature reduction, and improving the temperature reduction and sound-absorbing effects on the cabinet body.

[0013] Optionally, the elastic component includes: A positioning column, which is arranged on the inner side wall of the cabinet body and slidably penetrates through the cooling plate; A spring, which is sleeved on the positioning column and abuts against the cabinet body and the cooling plate for positioning. The sound-absorbing cotton is provided with an avoidance hole for the spring to pass through and the area of the sound-absorbing cotton is larger than that of the cooling plate and can realize a certain support for the cooling plate; A positioning nut, which is threadedly connected to the positioning column and abuts against the cooling plate for positioning.

[0014] By adopting the above technical solution, multiple springs are respectively sleeved on multiple positioning columns, the heat sink is plugged into the multiple plug holes on the silencer cotton, the silencer cotton is pushed against the cooling plate, and then the multiple positioning columns are passed through the cooling plate, so that the multiple springs pass through the multiple avoidance holes respectively, and finally the positioning nuts are threadedly connected to the positioning columns for positioning, so that the springs are pressed against the cooling plate and the cabinet for positioning, thereby realizing the installation and replacement of the cooling plate, heat sink and silencer cotton.

[0015] Optionally, a plurality of air inlets are evenly arranged on the side wall of the cabinet away from the cooling plate, and a blowing assembly is also arranged on the cabinet, and the blowing assembly includes: A fan is arranged in the cabinet and located at the air inlet and is used to blow air to cool the cooling plate; The filter plate is arranged at the air inlet and is used to prevent dust from passing through.

[0016] By adopting the above technical solution, the fan is started, so that the hot air in the cabinet is moved to the cooling plate for cooling, so that more heat can be dissipated through the heat sink, thereby improving the cooling effect of the cabinet, and as the flow rate of the air in the cabinet toward the cooling plate increases, more noise can be moved to the cooling plate and the silencer cotton for elimination, thereby improving the cooling and silencing effects at the same time, and the filter plate can filter impurities in the air, reducing the probability of impurities entering the cabinet and causing damage to the cabinet.

[0017] Optionally, a mounting hole is provided on the top of the cabinet and a mounting plate for sealing the mounting hole is detachably provided, a heat sink 1 and a heat sink 2 for heat dissipation are respectively installed on the cabinet at the air inlet and the cooling plate, the fan and the positioning column are arranged on the heat sink 1 and the heat sink 2, and the cooling component is arranged on the outside of the cabinet and connected to the cooling plate through the mounting hole.

[0018] By adopting the above technical solution, after removing the mounting plate, screw the positioning nut and then move the cooling plate, so that the heat sink is separated from the cabinet, and then the heat sink one and the heat sink two can be removed, and then the fan, the cooling component and the elastic component can be taken out for replacement. Compared with replacement in the cabinet, the convenience of replacement is greatly improved, and the cooling component is arranged on the outside of the cabinet, so that the area of ​​the cooling plate and the silencer cotton can be maximized, and the risk of interference with the electrical components in the cabinet is also reduced, thereby further improving the cooling and silencing effects.

[0019] Optionally, a plurality of air inlet pipes connected to a plurality of air inlets are arranged on the heat dissipation plate, and sound-absorbing cotton is positioned on the plurality of air inlet pipes.

[0020] By adopting the above technical solution, a plurality of air inlet pipes are inserted and installed on the sound-absorbing cotton, and at the same time, the sound-absorbing cotton can eliminate the noise in the cabinet, so that the noise in the cabinet can be greatly reduced without interfering with the air entering the cabinet, and the cooling and sound absorption effects are further improved.

[0021] Optionally, a vacuum pumping mechanism is provided on the liquid storage tank, and the vacuum pumping mechanism includes: A buoyancy plate that floats on the liquid surface and is evenly provided with ventilation holes; A telescopic member that is provided on the buoyancy plate and communicates with the liquid outlet pipe to return the liquid in the liquid outlet pipe to the liquid storage tank located below the buoyancy plate; A waterproof and breathable membrane that is provided on the buoyancy plate to block the liquid from passing through the ventilation holes and allow air to pass through; A liquid inlet and air extraction assembly for adding a cooling medium to the liquid storage tank located below the buoyancy plate and extracting the air in the liquid storage tank located above the buoyancy plate.

[0022] By adopting the above technical solution, when the pump body is started, the cooling medium flows back to the liquid storage tank through the liquid outlet pipe and the telescopic member, and when the cooling medium in the liquid storage tank decreases and the liquid level drops, the buoyancy plate drives the telescopic member to move, thereby reducing the flow space of the cooling medium, so that the cooling medium can also fill the liquid outlet pipe and the telescopic member when flowing back, reducing the probability of noise caused by the cooling medium not being full, and at the same time, the vacuum environment further reduces the generation of noise, thereby further improving the cooling and sound absorption effects. After the cooling medium in the liquid storage tank decreases, the cooling medium can also be added to the liquid storage tank through the liquid inlet and extraction assembly and the liquid storage tank can be evacuated.

[0023] Optionally, the liquid inlet and air extraction assembly includes: A liquid adding pipe that is provided on the liquid storage tank and extends to the inner bottom wall of the liquid storage tank and is provided with a liquid inlet valve for controlling opening and closing; An air extraction pipe that is on the upper surface of the liquid storage tank and communicates with the inside of the liquid storage tank. The air extraction pipe is provided with an air extraction valve for controlling opening and closing and is used for detachably connecting with a vacuum pump.

[0024] By adopting the above technical solution, when the liquid inlet valve is opened, the cooling medium is added to the liquid storage tank through the liquid adding pipe. At the same time, the air extraction pipe is connected to the vacuum pump, and the vacuum pump is started to extract the air in the liquid storage tank. As the cooling medium is added and the air is extracted, the air in the liquid storage tank can move upward and be extracted after passing through the waterproof and breathable membrane, thereby reducing the risk of the cooling medium entering the vacuum pump. Until the cooling medium is added completely, the liquid inlet valve is closed, and then the vacuum pump is started continuously to extract all the air in the liquid storage tank, and finally the air extraction valve is closed, so as to realize adding the cooling medium and evacuating the liquid storage tank.

[0025] In a second aspect, the magnetically controlled reactor provided by the present application adopts the following technical solution: Magnetic control reactor, the magnetic control reactor includes a cabinet body and a noise reduction and temperature reduction device arranged on the cabinet body.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. The temperature reduction component cools the temperature reduction plate, and at the same time, heat dissipation is carried out through the heat sink, thereby greatly reducing the temperature of the temperature reduction plate. The temperature reduction plate can well cool the cabinet body, and at the same time, the sound absorption cotton can eliminate the noise generated in the cabinet body, so that temperature reduction and noise reduction can be achieved simultaneously. The noise reduction of the sound absorption cotton does not affect the temperature reduction of the temperature reduction plate, so the temperature reduction and noise reduction effects are improved at the same time.

[0027] 2. By cooling, a pressure difference is formed in the air pressure inside the cabinet, so that the hot air inside the cabinet flows towards the temperature reduction plate. Due to the gas flow direction, the noise generated inside the cabinet also moves towards the temperature reduction plate and the sound absorption cotton in the gas flow direction and is eliminated, thereby further improving the temperature reduction and noise reduction effects.

[0028] 3. Since the propagation speed of noise in liquid is slower than that in metal, the cooling medium can also slow down the propagation speed of noise when the noise passes through it, so that the cooling medium can achieve the two effects of temperature reduction and noise reduction.

Detailed implementation manners

[0031] The following further elaborates on this application in detail.

[0032] The embodiment of this application discloses a sound insulation and temperature reduction device for a magnetically controlled reactor.

[0033] Referring to Figure 1 and Figure 2 , the sound insulation and temperature reduction device for a magnetically controlled reactor includes a sound insulation and temperature reduction mechanism 3 arranged on the cabinet body 1, and the sound insulation and temperature reduction mechanism 3 is used for cooling the cabinet body 1 and eliminating the noise generated inside the cabinet body 1 at the same time.

[0034] Referring to Figure 2 and Figure 3 , the cabinet body 1 has a cube or cuboid structure. An open mounting hole 11 is formed at the top of the cabinet body 1, and a mounting plate 12 for blocking the mounting hole 11 is fixedly installed by screws; a plurality of air inlets 13 for air passage are vertically spaced on one side wall of the cabinet body 1. A first heat dissipation plate 14 and a second heat dissipation plate 15 are vertically inserted and installed on the inner side wall of the cabinet body 1 communicating with the air inlet 13 and the opposite inner side wall respectively. A guide rail for vertically inserting the first heat dissipation plate 14 and the second heat dissipation plate 15 is fixedly installed inside the cabinet body 1; a plurality of air inlet pipes 16 corresponding to the plurality of air inlets 13 are fixedly installed on the side wall of the first heat dissipation plate 14 close to the air inlet 13.

[0035] The cabinet 1 is also provided with a blowing assembly 2, which includes a fan 21 and a filter plate 22. The fan 21 is fixedly mounted on the side wall of the heat sink 14 away from the air inlet pipe 16, and the fan 21 is started so that the outside air moves to the fan 21 through the air inlet 13 and the air inlet pipe 16, and then the air blows to the heat sink 2 15. Multiple air inlet pipes 16 are provided with sound-absorbing cotton 17, and multiple through holes are provided on the sound-absorbing cotton 17 for positioning with multiple air inlet pipes 16, so that the sound-absorbing cotton 17 is sleeved on the multiple air inlet pipes 16, and the sound-absorbing cotton 17 can eliminate noise without interfering with the passage of air; the filter plate 22 is fixedly mounted on the outer wall of the cabinet 1, and the filter plate 22 covers multiple air inlets 13, so as to filter the air entering the air inlets 13.

[0036] Reference Figures 2-4 The noise-absorbing and cooling mechanism 3 includes a cooling plate 31 and a noise-absorbing cotton 5. The cooling plate 31 is detachably mounted on the heat sink 15 through a plurality of elastic components 6. The wind blown out by the fan 21 moves toward the cooling plate 31. The noise-absorbing cotton 5 is located between the cooling plate 31 and the heat sink 15, and a plurality of elastic components 6 pass through the noise-absorbing cotton 5. The noise-absorbing cotton 5 is provided with a plurality of avoidance holes 51 for the elastic components 6 to pass through, thereby realizing the installation of the noise-absorbing cotton 5 between the cooling plate 31 and the heat sink 15. The plurality of elastic components 6 are used to buffer and reduce vibration of the cooling plate 31 under the action of elastic force.

[0037] A plurality of heat sinks 33 for heat dissipation are fixedly mounted on the side wall of the cooling plate 31 on the side close to the heat sink 15. The heat sinks 33 pass through the heat sink 15 and the cabinet 1 in sequence and extend to the outside of the cabinet 1. The heat sink 33 is used to dissipate the heat on the cooling plate 31 into the air. The sound-absorbing cotton 5 is provided with a plurality of plug holes 52 that are plugged with the heat sink 33, so that the sound-absorbing cotton 5 and the cooling plate 31 are connected to each other, and the sound-absorbing cotton 5 can achieve a certain supporting effect on the cooling plate 31. The sound-absorbing cotton 5 is used to eliminate noise. At the same time, the sound-absorbing cotton 5 extends to the outside of the cooling plate 31 and the heat sink 15, thereby increasing the area of ​​the sound-absorbing cotton 5 and improving the noise elimination effect.

[0038] The elastic component 6 includes a positioning column 61, a spring 62 and a positioning nut 63. The positioning column 61 is fixedly installed on the heat sink 15, and the positioning column 61 is slidably penetrated on the cooling plate 31; the spring 62 is sleeved on the positioning column 61, and the spring 62 passes through the plug hole 52, the positioning nut 63 is threadedly connected to the positioning column 61, and the two ends of the spring 62 are pressed against the cooling plate 31 and the heat sink 15, and the positioning nut 63 is pressed against the cooling plate 31 for positioning.

[0039] Reference Figure 2 , Figure 4 and Figure 5, the sound insulation and temperature reduction mechanism 3 further includes a temperature reduction component 4. The temperature reduction component 4 is used to introduce a flowing cooling medium for temperature reduction into the temperature reduction cavity 32. The cooling medium can cool the temperature reduction plate 31. Since the propagation speed of noise in liquid is slower than that in metal, the cooling medium can also achieve a certain sound insulation effect on the noise, that is, the cooling medium can achieve two effects of temperature reduction and sound insulation. Moreover, the sound passing through the cooling medium and the temperature reduction plate 31 can be further eliminated by the sound insulation cotton 5. The temperature reduction plate 31 is cooled by the cooperation of the heat dissipation fins 33, the cooling medium and the fan 21, so that the setting of the sound insulation cotton 5 will not cause the reduction of the temperature reduction effect, thereby improving the temperature reduction and sound insulation effects at the same time.

[0040] Refer to Figure 2 , Figure 5 and Figure 6 , the temperature reduction component 4 includes a liquid storage tank 41, a pump body 42, a liquid inlet pipe 43 and a liquid outlet pipe 44. A support plate is fixedly installed on the outer side wall of the cabinet body 1. The liquid storage tank 41 is placed on the upper surface of the support plate and is filled with a cooling medium. The pump body 42 is fixedly installed in the liquid storage tank 41. The liquid inlet pipe 43 is fixedly installed on the pump body 42, and the other end of the liquid inlet pipe 43 is fixedly connected to the upper surface of the temperature reduction plate 31 through the installation hole 11. At the same time, the liquid outlet pipe 44 is fixedly installed on the lower surface of the temperature reduction plate 31, and the other end of the liquid outlet pipe 44 passes through the installation hole 11 and is fixedly connected to the upper surface of the liquid storage tank 41. Both the liquid inlet pipe 43 and the liquid outlet pipe 44 are communicated with the inside of the temperature reduction cavity 32.

[0041] When the pump body 42 is started, the cooling medium is added into the temperature reduction cavity 32 through the liquid inlet pipe 43, and then the cooling medium in the temperature reduction cavity 32 flows back to the liquid storage tank 41 through the liquid outlet pipe 44, so as to cool the temperature reduction plate 31. At the same time, when the fan 21 is started, the heat on the temperature reduction plate 31 can be dissipated into the air more quickly through the plurality of heat dissipation fins 33, thereby improving the heat dissipation and temperature reduction effect inside the cabinet body 1.

[0042] On the inner side wall of the cabinet body 1 where the air inlet 13 is opened and outside the air inlet 13 and the fan 21, a plurality of air outlets are opened, so that the air inside the cabinet body 1 can be blown out through the air outlets. Sound insulation cotton 5 is also provided on the two inner side walls of the cabinet body 1 on the side of the heat dissipation plate one 14 and the heat dissipation two, thereby further improving the sound insulation effect; when the positioning nut 63 is screwed away from the temperature reduction plate 31 and the temperature reduction plate 31 is moved so that the heat dissipation fins 33 are separated from the cabinet body 1, the temperature reduction plate 31 structure can be taken down by moving the heat dissipation plate two 15 upward, and the installation can be realized by operating in the reverse direction.

[0043] Refer to Figure 5 and Figure 6, a vacuum pumping mechanism 7 is provided on the liquid storage tank 41. The vacuum pumping mechanism 7 includes a buoyancy plate 71, a telescopic member 72, a waterproof and breathable membrane 73, and a liquid inlet and air extraction assembly 8. The buoyancy plate 71 is vertically slidably installed in the liquid storage tank 41 and floats on the surface of the cooling medium. The telescopic member 72 is fixedly installed at the connection between the liquid outlet pipe 44 and the liquid storage tank 41 and is vertically downwardly fixedly connected to the buoyancy plate 71. At the same time, the telescopic member 72 has a vertical telescopic effect and guides the cooling medium in the liquid outlet pipe 44 into the liquid storage tank 41 below the buoyancy plate 71; a plurality of ventilation holes 74 vertically penetrating the buoyancy plate 71 are spaced apart on the buoyancy plate 71. The waterproof and breathable membrane 73 is fixedly installed on the lower surface of the buoyancy plate 71, and the waterproof and breathable membrane 73 blocks the cooling medium from passing through the ventilation holes 74 and allows air to pass through the ventilation holes 74.

[0044] The liquid inlet and air extraction assembly 8 is used to add the cooling medium into the liquid storage tank 41 below the buoyancy plate 71 and extract the air in the liquid storage tank 41 above the buoyancy plate 71. The liquid inlet and air extraction assembly 8 includes a liquid adding pipe 81 and an air extraction pipe 82. The liquid adding pipe 81 is fixedly installed on the upper surface of the liquid storage tank 41, and the liquid adding pipe 81 vertically penetrates the buoyancy plate 71 and extends to below the buoyancy plate 71. A liquid inlet valve 83 for controlling opening and closing is fixedly installed on the liquid adding pipe 81; the air extraction pipe 82 is fixedly installed on the upper surface of the liquid storage tank 41 and is communicated with the inside of the liquid storage tank 41 above the buoyancy plate 71. An air extraction valve 84 for controlling opening and closing is fixedly installed on the air extraction pipe 82. The air extraction pipe 82 is used to connect to a vacuum pump for extracting the air in the liquid storage tank 41.

[0045] The buoyancy plate 71 moves downward under the action of gravity, and the telescopic member 72 is used to position the buoyancy plate 71. When adding the cooling medium, the cooling medium is added into the liquid storage tank 41 through the liquid inlet pipe 43. The addition of the cooling medium causes the air in the liquid storage tank 41 to move above the buoyancy plate 71 through the waterproof and breathable membrane 73. The vacuum pump is started to extract the air in the liquid storage tank 41 through the air extraction pipe 82. After the liquid surface of the cooling medium contacts the buoyancy plate 71, it pushes the buoyancy plate 71 to move upward until the addition of the cooling medium is completed, and then the vacuum pump continues to start until the vacuum pumping ends, so as to complete the addition of the cooling medium and the vacuum pumping. The vacuum pumping can make the cooling medium flow more easily and reduce the propagation of noise, further improving the cooling and noise reduction effects.

[0046] The pump body 42 is started to make the cooling medium flow back into the liquid storage tank 41 below the buoyancy plate 71 through the liquid outlet pipe 44 and the telescopic member 72. When the liquid surface of the cooling medium changes, the buoyancy plate 71 can automatically move vertically, so that the internal space can meet the change in the liquid volume, and the cooling medium passing through the liquid outlet pipe 44 and the telescopic member 72 can fill the internal spaces of the liquid outlet pipe 44 and the telescopic member 72, thereby reducing the risk of noise caused by non-fullness and further improving the cooling and noise reduction effects.

[0047] The working principle of the embodiment of the present application is as follows: The fan 21 starts, causing the outside air to blow towards the cooling plate 31 for cooling, so that the hot air in the cabinet body 1 moves to the cooling plate 31 for cooling. At the same time, the pump body 42 starts, causing the cooling medium to enter the cooling cavity 32 to cool the cooling plate 31, and the heat on the cooling plate 31 dissipates through the heat sink 33. The noise in the cabinet body 1 moves to the sound-absorbing cotton 5 under the action of air flow for elimination, and the air in the cabinet body 1 is removed through the air outlet. Some of the uneliminated noise moves to the sound-absorbing cotton 17 for further elimination, so that noise can be eliminated while the cabinet body 1 is cooled, and the cooling and sound-absorbing effects are improved at the same time.

[0048] When the pump body 42 starts, the cooling medium flows back to the liquid storage tank 41 located below the buoyancy plate 71 through the liquid outlet pipe 44 and the telescopic member 72. When the liquid level of the cooling medium changes, the buoyancy plate 71 can automatically move vertically, so that the internal space can meet the change of the liquid volume, and the cooling medium passing through the liquid outlet pipe 44 and the telescopic member 72 can fill the internal space of the liquid outlet pipe 44 and the telescopic member 72, thereby reducing the risk of noise caused by non-fullness and further improving the cooling and sound-absorbing effects.
