Description
Technical Field
[0001] The invention belongs to the technical field of electric power equipment, and in particular relates to a box-type power supply control cabinet. Background Art
[0002] The PCS integrated box is a comprehensive power equipment that integrates multiple devices such as energy storage converter (PCS), boost transformer, high-voltage ring network cabinet, low-voltage distribution box, etc. in one container or combines them into one. Traditional energy storage systems usually undergo two voltage conversions during the conversion process, while the energy storage converter and booster (PCS) can combine these two processes into one, thereby reducing the loss of conversion energy and improving the efficiency of the system.
[0003] The PCS integrated cabin of the box-type transformer also has some disadvantages. The following is a detailed analysis of its disadvantages: Heat dissipation problem: Since the PCS booster integrates multiple devices in a relatively small space, its heat dissipation performance may be affected to a certain extent. Especially when running under high load, if the heat dissipation design is unreasonable or the heat dissipation system fails, it may cause the equipment temperature to rise, thus affecting the operation stability and life of the equipment. However, due to the closed internal space of the existing box-type PCS integrated cabin, the internal heat cannot be quickly dissipated; Safety issues: Although safety factors are taken into consideration when designing the PCS integrated cabin of the box-type transformer, there are still certain safety hazards during actual operation. For example, if the equipment fails or is operated improperly, it may cause an electrical accident. When an electrical fire occurs, the traditional integrated cabin is not designed with a corresponding fire extinguishing system, which makes it impossible to prevent the development of the fire. In addition, traditional electrical fires are extinguished using dry powder fire extinguishers, but dry powder particles have the risk of damaging compact electronic instruments. Therefore, how to achieve fire extinguishing while reducing unnecessary damage to equipment is also an issue that needs to be solved urgently. Summary of the invention

[0018] (4) In the present invention, when an electrical fire occurs, the high-pressure gas in the energy storage tank is introduced into the sodium bicarbonate storage tank, so that the sodium bicarbonate substance reacts with the citric acid substance and generates a large amount of carbon dioxide gas, and the carbon dioxide gas is used to extinguish the fire inside the integrated control box. The thermal insulation effect of the thermal insulation tank can prevent the citric acid from decomposing due to heat, and the desiccant can be used to absorb the water generated by the reaction to prevent the water from damaging the electrical equipment. In addition, compared with dry powder fire extinguishing, the use of carbon dioxide fire extinguishing can reduce the damage to the electrical equipment and avoid the risk of dry powder damaging precision instruments.

[0025] According to the above structure, when all the side box doors 2 are closed and the half door panel 204 slides down and squeezes the corresponding spring 1 206, the opening 1 202 on the upper part of the side box door 2 and the opening 2 205 on the half door panel 204 will overlap and communicate with each other. At this time, the integrated control box 1 will have a large window for air circulation, which is convenient for quickly discharging the internal heat of the integrated control box 1.

The top of the inner wall of the integrated control box 1 is slidably assembled with a plate frame 301, and the telescopic output end of the cylinder 302 is fixedly connected to the plate frame 301, and the four corners of the plate frame 301 are integrally provided with groove rods 303; Refer to the attached Figure 3-Figure 5The bottom of the base 304 is rotatably assembled with gear 1 305 and gear 2 306, gear 1 305 is meshed with gear 2 306, and the bottom of gear 1 305 is coaxially fixedly assembled with a sprocket 307, the top of gear 2 306 is coaxially fixedly assembled with an eccentric wheel, and the end of the eccentric wheel away from the center of the circle is fixedly welded with a vertical rod 308, and the vertical rod 308 movably passes through the corresponding slot rod 303.
[0027] Refer to the attached Figure 3-Figure 5 A sleeve 309 is fixedly provided on the inner wall of the integrated control box 1 and above each rotating seat 102. A rotating drum 310 is rotatably assembled inside each rotating seat 102, and a spiral guide groove 311 is opened on the inner wall of the rotating drum 310. A rectangular through rod 312 is slidably assembled inside the sleeve 309. A through column 313 penetrating the corresponding rotating drum 310 is integrally provided at the bottom of the rectangular through rod 312. A ball protrusion 314 is fixedly provided on the outer wall of the through column 313, and the ball protrusion 314 is slidably embedded in the corresponding spiral guide groove 311. A semi-cylinder 315 is integrally provided at the bottom of the through column 313. The vertical pin 207 is embedded in the inner side of the corresponding semi-cylinder 315 when the side box door 2 is closed. The sprocket 307 is connected to the two adjacent rotating drums 310 through a sleeved chain 316.
[0028] According to the above structure, when the side box door 2 is closed, the vertical pin 207 on the top of each half door panel 204 will be embedded in the inner side of the corresponding half cylinder 315. When the ventilation function of the control box needs to be turned on, the cylinder 302 is started and the plate frame 301 is driven to move horizontally. Since the vertical rods 308 penetrate the corresponding groove rods 303, the plate frame 301 will drive the gears 2 306 to rotate together when moving, and then drive the sprocket 307 to rotate by means of the meshing of the gear 1 305 and the gear 2 306, and then drive the corresponding rotating drum 310 to rotate through the chain 316. After the rotating drum 310 rotates, according to the rotation direction of the spiral guide groove 311, the column 31 The connecting rectangular through rod 312 will move downward in a straight line, and finally push the vertical pin 207 downward through the semi-cylinder 315, and each half door panel 204 will move downward at the same time, so that the first through port 202 and the second through port 205 overlap, so that the integrated control box 1 has a large window for air flow. In the above process, the through component 3 controls the downward movement of each half door panel 204, so that each side box door 2 has a grille opening for ventilation. Under this condition, it is convenient to quickly extract the internal heat of the integrated control box 1. The movable half door panel 204 can selectively open the side box door 2 for ventilation, and the opening condition can be determined according to the internal temperature environment and the external weather environment.
[0029] The working principle of the present invention is as follows: when the side box door 2 is closed, the vertical pin 207 on the top of each half door panel 204 will be embedded in the inner side of the corresponding half cylinder 315. When the ventilation function of the control box needs to be turned on, the cylinder 302 is started and the plate frame 301 is driven to move horizontally. Since each vertical rod 308 passes through the corresponding groove rod 303, the plate frame 301 will drive each gear 2 306 to rotate together when moving, and then the sprocket 307 is driven to rotate by the meshing of the gear 1 305 and the gear 2 306, and then the chain 316 drives the plate frame 301 to rotate.

When each half door panel 204 moves downward at the same time and squeezes the corresponding spring 1 206, the through port 1 202 on the upper half of the side box door 2 and the through port 2 205 of the half door panel 204 will overlap and communicate with each other. At this time, the integrated control box 1 has a large-area window for air circulation, which is convenient for the rapid removal of internal heat of the integrated control box 1.
[0030] Embodiment 2: Refer to the attached Figure 6-Figure 7 The temperature difference power assembly 4 includes several groups of copper tubes 1 401 and copper tubes 2 404 integrated, and the copper tubes 1 401 and copper tubes 2 404 are integrated and arranged in four groups and are symmetrically distributed. The copper tube 1 401 is fixedly installed on the lower surface of the top plate of the integrated control box 1, and the copper tube 2 404 is fixedly installed on the upper surface of the top plate of the integrated control box 1. The copper tube 2 404 is located directly above the corresponding copper tube 1 401, and the insulation filling 408 is filled between the two. The internal sliding assembly of the copper tube 1 401 There is a live tube 402, a liquid plug 405 is fixedly arranged inside the copper tube 404, and the liquid plug 405 extends to the inside of the corresponding live tube 402, a copper sleeve 403 is embedded in the outer wall of the top of the live tube 402, and the upper half of the inside of the live tube 402 is filled with silicone oil 406, and a coolant tank 407 is sealed and assembled on the top of each copper tube 404, and cooling water is stored in the coolant tank 407, and a connecting block 409 is fixedly arranged at the bottom of each live tube 402.
[0031] Refer to the attached Figure 6-Figure 7, a pry bar 410 is rotatably installed on the top of one end of the integrated control box 1, and the four pry bars 410 are divided into two groups and are symmetrically arranged. The end of the pry bar 410 away from the fulcrum is connected to the corresponding connecting block 409, and a gas injection tank 412 is fixedly installed at one end of the top plate of the integrated control box 1. The interior of the gas injection tank 412 is telescopically assembled with a gas plug, and the gas plug extends to the bottom end of the outside of the gas injection tank 412 and is fixedly connected with a connecting rod 411, the connecting rod 411 is connected to the end of the four pry bars 410 close to the fulcrum, and the connecting rod 411 is lifted and arranged on the top of one end of the integrated control box 1, the top of the gas injection tank 412 is respectively fixedly connected with a gas injection pipe 413 and a gas supply pipe 414, and the ends of the gas injection pipe 413 and the gas supply pipe 414 close to the gas injection tank 412 are equipped with one-way valves, and the gas supply pipe 414 is in an inverted U shape.
[0032] According to the above structure, the copper tube 1 401 located inside the integrated control box 1 is heated by the high temperature in the box. When the copper sleeve 403 is placed inside the copper tube 1 401, the high temperature of the copper tube 1 401 is transferred to the copper sleeve 403 and directly heats the silicone oil 406 inside the live tube 402. With the high temperature resistance and heat expansion characteristics of the silicone oil 406, the live tube 402 moves upward under the power of liquid expansion. With the movement of the live tube 402, the copper sleeve 403 will move to the inside of the copper tube 2 404. The cooling water inside the coolant tank 407 is directly heated by the temperature conduction between the copper tube 2 404 and the copper sleeve 403. Then, the silicone oil 406 is cooled, and the silicone oil 406 shrinks due to the cold, causing the live tube 402 to move down again. The thermal insulation filler 408 is used to prevent the temperature from being conducted between the copper tube 1 401 and the copper tube 2 404. In this way, the live tube 402 will continuously move up and down, and the live tube 402 can reciprocate to pry the corresponding pry rod 410, and finally the connecting rod 411 will be driven to reciprocate up and down, and the air plug will continuously expand and contract inside the gas injection tank 412, so that positive and negative pressures are continuously formed inside the gas injection tank 412, and the external air is sucked into the gas injection tank 412 through the gas supplement pipe 414, and then squeezed out through the gas injection pipe 413; Furthermore, the inverted U-shaped air supply pipe 414 can prevent rainwater from entering the air filling tank 412. The setting of the pry rod 410 can drive the connecting rod 411 to move with a smaller force. In addition, the four live tubes 402 move up and down synchronously and jointly drive the connecting rod 411 to move, further sharing the required power and making it possible to use the thermal expansion and contraction of the liquid as the premise of kinetic energy.
[0033] Refer to the attached Figure 8-Figure 9The single negative pressure energy storage assembly 5 includes an energy storage tank 501 fixedly installed above the integrated control box 1, a piston 502 is telescopically assembled inside the energy storage tank 501, and one end of the piston 502 extending to the outside of the energy storage tank 501 is fixedly connected to an end plate 503, a guide sleeve 505 is fixedly arranged on the outer wall of one end of the energy storage tank 501, and guide rods 504 that movably penetrate the corresponding guide sleeves 505 are fixedly installed at both ends of the end plate 503, and a spring 506 is connected between the end of the guide rod 504 and the side wall of the corresponding guide sleeve 505, and the other end of the energy storage tank 501 is connected to the gas injection The ends of the tube 413 are connected and are also connected to an air outlet pipe 507, the end of the air outlet pipe 507 is connected and assembled with an air valve 508, another interface of the air valve 508 is connected to an air pipe 1 509, the end of the air pipe 1 509 is connected and assembled with a three-way regulating valve 514, the other three interfaces of the three-way regulating valve 514 are respectively connected to two air pipes 2 515 and an air vent pipe 519, the two air pipes 2 515 are fixedly installed on the top of both sides inside the integrated control box 1, and the outer wall of the air pipe 2 515 is array-mounted with inclined nozzles 516 inclined toward the side box door 2.
[0034] Refer to the attached Figure 8-Figure 9 A valve core 510 for controlling the flow of air between the air outlet pipe 507 and the air pipe 1 509 is slidably installed inside the air valve 508, a lever 512 is fixedly connected to the bottom of the end plate 503, and push rods 513 for pushing the valve core 510 are symmetrically fixedly welded at both ends of the lever 512, a channel 511 is penetrated through the middle of the valve core 510, a three-way regulating valve 514 is electrically connected to two anemometers 7, a branch pipe 517 is fixedly connected to one end of the air outlet pipe 507, and a solenoid valve 518 is assembled and connected to one end of the branch pipe 517 close to the air outlet pipe 507, a fire alarm is installed on the inner wall of the integrated control box 1, and the fire alarm is electrically connected to the solenoid valve 518.
[0035] According to the above structure, when the ventilation function of the control box is not turned on, the three-way regulating valve 514 is controlled to make the air pipe 1 509 and the air release pipe 519 open. When the ventilation function of the control box is turned on, the anemometers 7 located on both sides of the integrated control box 1 are used to detect the wind speed on both sides of the box. According to the principle that the wind speed has a small atmospheric pressure, the three-way regulating valve 514 is controlled to open the air pipe 2 515 located at the low pressure position. In addition, air is continuously injected into the energy storage tank 501 through the air injection pipe 413, the piston 502 will move and the corresponding spring 2 506 will be compressed at the same time. When the piston 502 moves to the limit position, the push rod at one end of the lever 512 513 will push the valve core 510, so that the channel 511 connects the air outlet pipe 507 and the air pipe 1 509. At this time, the high-pressure gas inside the energy storage tank 501 will be quickly squeezed into the air pipe 2 515 on the corresponding side, and finally sprayed to the side box door 2 on one side through the oblique nozzle 516. At this time, a high-speed airflow will pass through the vicinity of the side box door 2 located at the low-pressure position, and the air pressure in this position will be further reduced by this airflow. At this time, the air pressure on the other side of the integrated control box 1 is higher than that on this side. With the help of the air pressure difference on both sides, the air on the other side is driven to pass through the integrated control box 1 to move to this side, and the heat accumulated inside the integrated control box 1 is taken away by this airflow; In the above process, by opening the air pipe 2 515 on the low-pressure side, the high-speed airflow ejected from the oblique nozzle 516 increases the pressure difference on both sides of the integrated control box 1, and forms an airflow passing through the integrated control box 1 with the help of the pressure difference. The heat accumulated inside the integrated control box 1 is taken away with the help of the airflow, and the heat dissipation capacity of the integrated control box 1 is greatly improved in this way. The power for forming the pressure difference comes from the high-pressure gas stored in the energy storage tank 501, and the power for inflating the energy storage tank 501 comes from the kinetic energy of the reciprocating motion of the live tube 402 with the help of the temperature difference. The whole process not only makes full use of the thermal energy inside the integrated control box 1 to achieve thermal energy work, but also optimizes the scheme for using power equipment to reduce the power consumed in the process as much as possible.
[0036] The working principle of the present invention is: when the ventilation function of the control box is not turned on, the three-way regulating valve 514 is controlled to open the air pipe 1 509 and the air release pipe 519. When the ventilation function of the control box is turned on, the anemometers 7 located on both sides of the integrated control box 1 are used to detect the wind speed on both sides of the box. Based on the principle that the wind speed has a small atmospheric pressure, the three-way regulating valve 514 is controlled to open the air pipe 2 515 located at the low pressure position. The copper tube 1 401 located inside the integrated control box 1 is heated by the high temperature in the box. When the copper sleeve 403 is placed inside the copper tube 1 401, the high temperature of the copper tube 1 401 is transferred to the copper sleeve 403 and directly heats the silicone oil 406 inside the live tube 402. With the high temperature resistance and heat expansion characteristics of the silicone oil 406, the live tube 402 moves upward under the power of liquid expansion. As the live tube 402 moves, the copper sleeve 403 moves to the inside of the copper tube 2 404. The cooling water inside the coolant tank 407 directly heats the silicone oil through the temperature conduction between the copper tube 2 404 and the copper sleeve 403. 406 is cooled, and the silicone oil 406 shrinks due to the cold, causing the live tube 402 to move down again. The insulation filler 408 is used to prevent temperature conduction between the copper tube 1 401 and the copper tube 2 404. In this way, the live tube 402 will continue to move up and down, and the live tube 402 can pry the corresponding pry rod 410 back and forth, and finally the connecting rod 411 will be driven to move up and down back and forth, and the air plug will continue to expand and contract inside the air injection tank 412, so that positive and negative pressures are continuously formed inside the air injection tank 412, and the external air is sucked into the air injection tank 412 through the air supply pipe 414, and then squeezed out through the air injection pipe 413; Air is continuously injected into the energy storage tank 501 through the air injection pipe 413, the piston 502 will move and the corresponding spring 2 506 will be compressed at the same time. When the piston 502 moves to the limit position, the push rod 513 at one end of the lever 512 will push the valve core 510, so that the channel 511 connects the air outlet pipe 507 and the air pipe 1 509. At this time, the high-pressure gas in the energy storage tank 501 will be quickly squeezed into the air pipe 2 515 on the corresponding side, and finally sprayed to the side box door 2 on one side through the oblique nozzle 516. At this time, a high-speed airflow will pass through the vicinity of the side box door 2 located at the low pressure position. However, the air pressure in that direction is further reduced by means of this airflow. At this time, the air pressure on the other side of the integrated control box 1 is higher than that on that side. By means of the air pressure difference on both sides, the air on the other side is driven to pass through the integrated control box 1 to move to that side. By means of this airflow, the heat accumulated inside the integrated control box 1 is taken away. When the gas inside the energy storage tank 501 is exhausted, the piston 502 and the lever 512 are reset, and the push rod 513 at the other end of the lever 512 also pushes the valve core 510 to reset, and the air outlet pipe 507 and the air pipe 509 are disconnected and closed, and the air injection pipe 413 is used to re-inflate the energy storage tank 501.

[0039] According to the above structure, when the fire alarm inside the integrated control box 1 detects a fire, the solenoid valve 518 is opened, and the high-pressure gas in the energy storage tank 501 is injected into the sodium bicarbonate storage tank 602 through the branch pipe 517, and the push plug 603 pushes the sodium bicarbonate substance, the stopper 604 is pushed open and the sodium bicarbonate substance enters the citric acid storage tank 605 through the conduit, and the sodium bicarbonate substance reacts with the citric acid substance to produce a large amount of carbon dioxide gas and water, wherein the water will be absorbed by the desiccant inside the insulation tank 601, and the carbon dioxide gas will be injected into the integrated control through the fire pipe 607 and the nozzle 609. Box 1, to achieve the effect of fire extinguishing. In the above process, when an electrical fire occurs, the high-pressure gas in the energy storage tank 501 is introduced into the sodium bicarbonate storage tank 602, so that the sodium bicarbonate substance reacts with the citric acid substance and produces a large amount of carbon dioxide gas. With the help of the carbon dioxide gas, the effect of extinguishing the fire inside the integrated control box 1 is achieved. Among them, the insulation effect of the insulation tank 601 can prevent the citric acid from being decomposed by heat, and the desiccant can be used to absorb the water generated by the reaction to prevent moisture from damaging the power equipment. In addition, compared with dry powder fire extinguishing, the use of carbon dioxide fire extinguishing can reduce the damage to the power equipment and avoid the risk of dry powder damaging precision instruments.
[0040] The working principle of the present invention is as follows: when the fire alarm inside the integrated control box 1 detects a fire, the solenoid valve 518 opens, and the high-pressure gas in the energy storage tank 501 is injected into the sodium bicarbonate storage tank 602 through the branch pipe 517, and the push plug 603 pushes the sodium bicarbonate substance, the stopper 604 is pushed open and the sodium bicarbonate substance enters the citric acid storage tank 605 through the conduit, and the sodium bicarbonate substance reacts with the citric acid substance to produce a large amount of carbon dioxide gas and water, wherein the water is absorbed by the desiccant inside the insulation tank 601, and the carbon dioxide gas is injected into the integrated control box 1 through the fire pipe 607 and the nozzle 609, and the oxygen concentration in the air is reduced, thereby suffocating the burning of the flame, thereby achieving the effect of extinguishing the fire, and when the carbon dioxide is released to the fire scene, it will expand into gas and absorb heat, thereby reducing the temperature around the flame and further suppressing the burning of the flame.
