Description
Technical Field
[0001] The present invention relates to the field of high-voltage starting cabinets, and more specifically, it relates to a high-voltage solid-state soft starting cabinet. Background Art
[0002] The high-voltage solid-state soft starting device is a device for starting high-voltage AC motors. Its main components are three reverse-parallel thyristor modules connected between the power supply and the controlled motor and their electronic control devices. The high-voltage solid-state soft starting device is composed of multiple thyristors connected in series and parallel. By controlling the firing angle of the thyristors, the magnitude of the output voltage can be controlled, which can meet the different voltage and current requirements during the motor starting process. During the motor starting process, the high-voltage solid-state soft starting device increases the terminal voltage of the motor according to a pre-set starting curve, enabling the motor to accelerate smoothly, thereby reducing the electrical and mechanical impacts of the motor starting on the power grid, the motor, and the connected equipment.
[0003] Traditional high-voltage solid-state soft starting cabinets often adopt a single heat dissipation method, such as relying only on natural convection or a single exhaust fan for heat dissipation. This method often has low heat dissipation efficiency. Especially in the case of high load or high ambient temperature, the heat inside the chassis is difficult to effectively discharge, resulting in too high a temperature of the electronic components, which in turn affects their performance and lifespan. For this reason, we propose a high-voltage solid-state soft starting cabinet. Summary of the Invention
[0004] The present invention provides a high-voltage solid-state soft starting cabinet to solve the technical problem that in the related art, the heat inside the chassis is difficult to effectively discharge due to a single heat dissipation method, resulting in too high a temperature of the electronic components, which in turn affects their performance and lifespan.
[0005] The present invention provides a high-voltage solid-state soft starting cabinet, which includes a starting cabinet chassis. An electronic component installation area is provided therein, and on both sides of this area, a wind control mechanism one and a wind control mechanism two with the same structure but opposite functions are respectively configured. These two wind control mechanisms are respectively responsible for the suction and exhaust operations in opposite directions;
[0006] Both the wind control mechanism one and the wind control mechanism two include a plurality of longitudinally distributed air vents, exhaust fans, and impact control mechanisms. Each air vent is subdivided into an independent explosion port and a suction port. The exhaust fan works to drive the air inside the starting cabinet chassis to be discharged through the suction port. A gas cut-off piston is provided in the explosion port. When the air flow rate in the suction port drops below a preset value, the impact control mechanism is activated, and by reciprocating motion, it pulls the gas cut-off piston to allow high-pressure gas to intermittently spray out from the explosion port along the path of the corresponding suction port;
[0007] The wind control mechanism one and the wind control mechanism two alternately execute the suction and exhaust actions, prompting the rising air flow generated inside the chassis to be discharged in the horizontal direction.
[0008] Further, a chassis heat dissipation component is fixedly arranged on the back of the starting cabinet chassis, which is used to blow the air outside the starting cabinet chassis into the inside of the starting cabinet chassis, cool all the components in the electronic component installation area of the starting cabinet chassis, and make the air rise and flow inside the starting cabinet chassis to take away the temperature dissipated by the components.
[0009] Further, the air guiding mechanism I further includes an exhaust air box, which is fixedly arranged on the side wall chassis of the starting cabinet chassis.

A air intake is arranged at the central position on the exhaust side of the exhaust fans, and the air intake is fixedly connected to the exhaust air box.
[0010] Further, a connecting plate is arranged on the air intake side of the exhaust fan. The connecting plate is fixedly connected to the exhaust air box, and a longitudinal row plate is fixedly connected to the side of the connecting plate away from the exhaust air box.

A plurality of air inlets are fixedly arranged on one side of the longitudinal row plate, and the air suction port is communicated with the inside of the longitudinal row plate. An air supply pipe is arranged through the internal space of the longitudinal row plate.

A guide air pipe is arranged on the air intake. The guide air pipe corresponding to the air guiding mechanism I extends along the protective pipe and is communicated with the air supply pipe corresponding to the air guiding mechanism II. At the same time, the guide air pipe corresponding to the air guiding mechanism II also extends along the protective pipe and is communicated with the air supply pipe corresponding to the air guiding mechanism I.
[0012] Further, a blasting chamber is fixedly arranged inside the blasting port. A control column is fixedly arranged inside the blasting chamber. The air inlet end of the air supply pipe is fixedly connected with an expansion air bag. The expansion air bag corresponding to the air guiding mechanism I is communicated with the guide air pipe corresponding to the air guiding mechanism II. At the same time, the expansion air bag corresponding to the air guiding mechanism II is communicated with the guide air pipe corresponding to the air guiding mechanism I.
[0013] Further, an internal control pipe is fixedly arranged inside the control column. An air leakage groove is arranged on the inner side of one end of the internal control pipe close to the air jet direction of the control column. A cut-off piston is movably arranged inside the air leakage groove. The diameter of the cut-off piston is larger than the diameter of the internal control pipe and smaller than the diameter of the air leakage groove.
[0014] Further, a guide column penetrates through the inside of the cut-off piston. Both ends of the guide column are fixedly connected with the internal control pipe. The cut-off piston is slidably connected with the guide column. A push spring is sleeved outside the guide column on the side of the cut-off piston close to the expansion air bag.

A limit ring is fixedly arranged inside the support frame, a coil spring member is fixedly arranged inside the limit ring, a scroll fan member is arranged on one side of the coil spring member, and the central axis of the scroll fan member is fixedly connected to the center end of the coil spring member.

Detailed implementation manners
[0030] Now, the subject matter described herein will be discussed with reference to example embodiments. It should be understood that discussing these embodiments is only to enable those skilled in the art to better understand and thus implement the subject matter described herein. Without departing from the protection scope of the content of this specification, changes can be made to the functions and arrangements of the elements discussed. Each example can omit, substitute, or add various processes or components as needed. Additionally, the features described for some examples can also be combined in other examples.
[0031] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, a high-voltage solid-state soft starting cabinet includes a starting cabinet chassis 11, in which there is an electronic component installation area, and on both sides of this area, there are air control mechanisms one 2 and two 3 with the same structure but opposite functions, and these two air control mechanisms are respectively responsible for the air intake and exhaust operations in opposite directions;
[0032] Both the air control mechanism one 2 and the air control mechanism two 3 include a plurality of air outlets 23, exhaust fans 27, and impact control mechanisms 5 distributed longitudinally. Each air outlet 23 is subdivided into independent explosion impact ports 25 and air suction ports 26. The exhaust fan 27 works to drive the air inside the starting cabinet chassis 11 to be discharged through the air suction port 26. There is an air cut-off piston 47 arranged in the explosion impact port 25. When the air flow rate in the air suction port 26 drops below a preset value, the impact control mechanism 5 is activated, and by reciprocating motion, it pulls the air cut-off piston 47, allowing high-pressure gas to intermittently spray out from the explosion impact port 25 along the path corresponding to the air suction port 26;
[0033] The air control mechanism one 2 and the air control mechanism two 3 alternately perform air intake and exhaust actions, prompting the rising air flow generated inside the chassis to be discharged in the horizontal direction.
[0034] On the back of the starting cabinet chassis 11, a chassis heat dissipation component 12 is fixedly installed, which is used to blow the air outside the starting cabinet chassis 11 into the inside of the starting cabinet chassis 11, cool all the components in the electronic component installation area of the starting cabinet chassis 11, and make the air rise and flow inside the starting cabinet chassis 11 to take away the temperature dissipated by the components.
[0035] The air guiding mechanism 1 also includes an exhaust air box 21, which is fixedly installed on the side wall of the starting cabinet chassis 11. A plurality of exhaust fans 27 are fixedly installed inside the exhaust air box 21. The exhaust direction of the exhaust fans 27 is from the inside of the starting cabinet chassis 11 to the outside. At the central position on the side where the exhaust fans 27 exhaust air, an air intake port 28 is provided, and the air intake port 28 is fixedly connected to the exhaust air box 21.
[0036] On the side where the exhaust fans 27 intake air, a connecting plate 201 is provided. The connecting plate 201 is fixedly connected to the exhaust air box 21. And on the side of the connecting plate 201 away from the exhaust air box 21, a longitudinal row plate 22 is fixedly connected. The longitudinal row plate 22 is communicated with the exhaust air box 21 through the connecting plate 201. A plurality of air vents 23 are all fixedly installed on one side of the longitudinal row plate 22, and the air suction port 26 is communicated with the inside of the longitudinal row plate 22. An air supply pipe 42 passes through the internal space of the longitudinal row plate 22.
[0037] Below the corresponding connecting plates 201 of the air guiding mechanism 1 and the air guiding mechanism 2, a protection pipe 24 is provided. A guide air pipe 29 is provided on the air intake port 28. And the guide air pipe 29 corresponding to the air guiding mechanism 1 extends along the protection pipe 24 and is communicated with the air supply pipe 42 corresponding to the air guiding mechanism 2. At the same time, the guide air pipe 29 corresponding to the air guiding mechanism 2 also extends along the protection pipe 24 and is communicated with the air supply pipe 42 corresponding to the air guiding mechanism 1.
[0038] As Figure 5 、 Figure 6 、 Figure 7 and Figure 9 shown, inside the explosion impact port 25, an explosion impact chamber 41 is fixedly installed. Inside the explosion impact chamber 41, a control column 44 is fixedly installed. The air inlet end of the air supply pipe 42 is fixedly connected with an expansion air bag 43. The expansion air bag 43 corresponding to the air guiding mechanism 1 is communicated with the guide air pipe 29 corresponding to the air guiding mechanism 2. At the same time, the expansion air bag 43 corresponding to the air guiding mechanism 2 is communicated with the guide air pipe 29 corresponding to the air guiding mechanism 1.
[0039] Inside the control column 44, an internal control pipe 45 is fixedly installed. At one end of the internal control pipe 45 close to the jet direction of the control column 44, an air leakage groove 46 is opened on the inner side. A cut-off piston 47 is movably arranged inside the air leakage groove 46. The diameter of the cut-off piston 47 is larger than the diameter of the internal control pipe 45 and smaller than the diameter of the air leakage groove 46.
[0040] The inside of the air cut-off piston 47 is penetrated by a guide post 48. Both ends of the guide post 48 are fixedly connected to the internal control pipe 45. The air cut-off piston 47 is slidably connected to the guide post 48. A push spring 49 is sleeved outside the guide post 48 on the side of the air cut-off piston 47 close to the expansion airbag 43.
[0041] As Figure 7 and Figure 8 shown, the air control and impact mechanism 5 includes a support frame 54, and the support frame 54 is fixed to the inner wall of the air inlet 26. A limiting ring 52 is fixedly arranged inside the support frame 54. A spring winding member 53 is fixedly arranged inside the limiting ring 52. A scroll fan member 51 is arranged on one side of the spring winding member 53. The central axis of the scroll fan member 51 is fixedly connected to the center end of the spring winding member 53. Four extension plates 56 are evenly arranged on the fan blades of the scroll fan member 51.
[0042] A swing plate 57 is arranged on one side of the scroll fan member 51. The swing plate 57 is rotatably connected to the inner wall of the air inlet 26. A pulling control wire 55 is fixedly arranged at the upturned end of the swing plate 57. The side of the pulling control wire 55 away from the swing plate 57 is fixedly connected to the center position of the air cut-off piston 47.
[0043] The electronic components in the starting cabinet chassis 11 are installed in the electronic component installation area. When the starting cabinet chassis 11 is running normally, the air outside the starting cabinet chassis 11 is sucked into the inside of the starting cabinet chassis 11 through the operation of the chassis heat dissipation member 12 to cool the components in the electronic component installation area. Since the air inlet position of the chassis heat dissipation member 12 is at the lower half of the starting cabinet chassis 11, the air forms an upward air flow after entering and exiting the starting cabinet chassis 11 through the chassis heat dissipation member 12 to cool the components in the electronic component installation area;
[0044] Through the system of the starting cabinet chassis 11 itself, the corresponding exhaust fans 27 in the air control mechanism one 2 and the air control mechanism two 3 operate alternately. When the exhaust fan 27 in the air control mechanism one 2 operates, the exhaust fan 27 in the air control mechanism two 3 stops operating;
[0045] When the exhaust fan 27 works to suck in the air flow, when the air flow passes through the scroll fan member 51, it will drive the scroll fan member 51 to rotate clockwise, thereby applying a winding force to the spring winding member 53 through the central axis of the scroll fan member 51 until the maximum value of the spring winding member 53. The scroll fan member 51 will also stop rotating under the air flow and remain in the state of the maximum winding force of the spring winding member 53;
[0046] When the exhaust fan 27 in the first air control mechanism 2 operates, air vents 23 at different heights will horizontally suck the air in the height space of the electronic component installation area into the air suction port 26, then enter the vertical row plate 22 and is sucked into the exhaust air box 21 by the exhaust fan 27 via the connecting plate 201, and finally is blown out of the starting cabinet chassis 11 by the exhaust fan 27 through the exhaust air box 21. A plurality of air suction ports 26 are provided on each of the plurality of vertical row plates 22, so as to horizontally suck the air in different spaces. On the one hand, the dust following the upward airflow is horizontally sucked into the air suction port 26 and finally discharged from the starting cabinet chassis 11. The upward airflow from bottom to top needs to pass through the suction of multiple horizontal airflows, reducing the dust covering the electronic components. On the other hand, the heat dissipated by the electronic components is sucked away by the horizontal airflow, reducing the upward diffusion of heat along with the upward airflow and reducing the impact on the components in other height spaces;
[0047] When the exhaust fan 27 in the first air control mechanism 2 operates, a part of the discharged air will be blown into the air receiving port 28, rush into the air supply pipe 42 in the second air control mechanism 3 along the air guide pipe 29, and finally flow into the expansion air bag 43. The connection point between the expansion air bag 43 and the air supply pipe 42 is connected by a one-way valve. As the air gradually enters the expansion air bag 43, the expansion air bag 43 gradually expands and is gradually pressurized;
[0048] At the same time, the exhaust fan 27 corresponding to the second air control mechanism 3 stops working, and the vortex fan part 51 loses the impact of the airflow. The elastic force of the coil spring part 53 drives the vortex fan part 51 to rotate counterclockwise. When the vortex fan part 51 rotates counterclockwise, the evenly distributed extension plates 56 will gradually push the swing plate 57 to swing. Each time the swing plate 57 swings, it can pull the pull control wire 55. The pull control wire 55 pulls the air cut-off piston 47 to slide along the guide post 48, so that the high-pressure gas in the expansion air bag 43 instantaneously passes through the air release groove 46 and is ejected by the control post 44. The instantaneously ejected gas is ejected along the direction of the explosion impact port 25, impacting the airflow flowing horizontally in this height space, instantaneously changing the suction airflow strength of the air suction port 26 in the first air control mechanism 2, which is beneficial to taking away the dust adsorbed on the surface of the components. Moreover, the intermittent explosion of gas is beneficial to impacting the dust on the surface of the components facing away from the suction direction of the air suction port 26 in the first air control mechanism 2;
[0049] The first air control mechanism 2 and the second air control mechanism 3 alternately execute the suction and exhaust actions, promoting the effective discharge of the upward airflow generated inside the chassis in the horizontal direction. At the same time, the flying dust is assisted to be removed by the explosion impact airflow in the horizontal direction, ensuring the cleanliness of the internal environment of the chassis and the effective heat dissipation of the electronic components.
[0050] Start-up and heat dissipation: After the starting cabinet chassis 11 starts, the chassis heat dissipation part 12 starts to work, sucking the external air into the chassis interior to cool the components in the electronic component installation area, and the air rises and flows inside the chassis, taking away the heat dissipated by the components.
[0051] The air guiding mechanisms operate alternately: The system controls the exhaust fans 27 in the air guiding mechanism one 2 and the air guiding mechanism two 3 to operate alternately. When the exhaust fan 27 of one air guiding mechanism operates, the exhaust fan 27 of the other air guiding mechanism stops operating.
[0052] Air intake and exhaust: The operating exhaust fan 27 sucks in air at different heights inside the chassis through the air intake ports 26, passes through the longitudinal plates 22 and the connecting plates 201, enters the exhaust box 21, and finally is discharged outside the chassis by the exhaust fan 27. The multiple air intake ports 26 and the longitudinal plates 22 provided ensure the horizontal suction of air in different spaces, effectively reducing dust coverage and heat dissipation between electronic components.
[0053] High-pressure gas explosion impulse: Some of the air discharged by the operating air guiding mechanism is blown into the air intake port 28, enters the expansion airbag 43 of the other air guiding mechanism through the air duct 29, and gradually expands and pressurizes it. When the exhaust fan of the other air guiding mechanism stops working, the turbofan member 51 rotates counterclockwise driven by the spiral spring member 53, pushes the swing plate 57 to swing through the extension plate 56, and then pulls the control wire 55 and the air cutoff piston 47 to slide. The sliding of the air cutoff piston 47 causes the high-pressure gas in the expansion airbag 43 to be instantaneously ejected from the air release groove 46 and the control column 44, forming an explosion impulse airflow that impacts the horizontally flowing airflow, which is beneficial to removing dust on the surface of the components.
[0054] Alternation and circulation: The air guiding mechanism one 2 and the air guiding mechanism two 3 alternately perform air intake and exhaust actions, as well as high-pressure gas explosion impulse, ensuring that the upward airflow generated inside the chassis is effectively discharged in the horizontal direction. Through this alternating and circulating method, the cleanliness of the internal environment of the chassis and the effective heat dissipation of electronic components are maintained.
[0055] The above describes the embodiments of this example, but this example is not limited to the above specific implementation manners. The above specific implementation manners are merely illustrative rather than restrictive. Under the inspiration of this example, those of ordinary skill in the art can also make many forms, all of which fall within the protection scope of this example.
