Description

Technical Field

[0001] The invention belongs to the field of SVG equipment, in particular to a heat dissipation type SVG equipment box. Background Art

[0002] SVG (static var generator) reactive power compensation device is a highly reliable, efficient and pollution-free high-voltage and high-power power quality management equipment. The basic principle of SVG is to use a self-commutated bridge circuit, connected in parallel to the power grid through a reactor or transformer, and adjust the phase and amplitude of the output voltage on the AC side of the bridge circuit, or directly control the AC side current, so that the circuit absorbs or emits reactive current that meets the requirements, thereby achieving the purpose of dynamic reactive power compensation. SVG devices are particularly important in power systems. They improve the power supply efficiency of power systems, improve the power supply environment of power networks, and make outstanding contributions to energy conservation and consumption reduction and power supply safety in industries such as coal, power grids, metallurgy, chemicals, electric railways, and wind power.

[0003] During the operation of SVG, power loss will cause the device to heat up and the temperature will rise, especially its IGBT power module, which is the main heat-generating component in SVG equipment. With the development of IGBT chip technology, the size of IGBT itself is getting smaller and smaller, but the power consumption is getting larger and larger, and the heat flux density is also greatly increased. Excessive temperature of components will shorten the service life of components, and in severe cases may even cause burnout, explosion and other accidents, which is the main reason for limiting the current and voltage capacity of power electronic devices. The stability of power device operation determines the operating performance of the entire SVG, and temperature has a great influence on the stability of power devices. Therefore, the heat dissipation performance of the heat dissipation device directly determines the operating performance and reliability of the SVG reactive power compensation equipment.

[0004] In the Chinese patent with publication number CN104882807B, a heat dissipation type SVG equipment box is mentioned, which contains a three-phase SVG power cabinet and a control cabinet, which are located in the power cabinet room and the control room. The power cabinets are placed face to face, and the power modules in the power cabinet are installed in a stacked array structure. A number of air duct holes are opened on the front and rear side walls of the box, and an air outlet fan is installed on the corresponding outer side of the box; a number of air inlet holes are opened on the front and rear side walls of the box, and shutters are installed on the air inlet holes respectively; a heat pipe heat dissipation device is installed inside the box, and its hot end is connected to the radiator of each power module in the power cabinet, and the cooling end is fixed on the outer side of the box; temperature measurement sensors are reasonably arranged inside the box.

[0005] However, although the existing heat dissipation type SVG equipment box can play a role in heat dissipation, it mostly adopts a fixed-point heat dissipation method for heat dissipation, and the position of the heat dissipation structure cannot be adjusted according to the specific heat dissipation location, so the heat dissipation energy consumption is large and the cost is increased.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 , Attachment Figure 5 and attached Figure 6 As shown:

[0036] Embodiment 1: The present invention provides a heat dissipation type SVG device box, comprising:

[0037] An installation box 1, a controller 10 is installed inside the installation box 1, and a plurality of temperature detectors 15 are installed inside the installation box 1;

[0038] A first electric guide rail 11 is installed inside the installation box 1, electric telescopic rods 14 are installed on both sides of the first electric guide rail 11, the bottom of the electric telescopic rod 14 is connected to the second electric guide rail 12, and an infrared rangefinder 24 is installed on the side of the second electric guide rail 12;

[0039] A guide rail slide 13 is slidably mounted on the front ends of the first electric guide rail 11 and the second electric guide rail 12. An electric push rod 16 is mounted on the surface of the guide rail slide 13 at the front end of the first electric guide rail 11. A docking box 18 is connected to the top of the electric push rod 16.

[0040] A docking hole 19 is provided inside the docking box 18, a mounting seat 21 is installed on the surface of the guide rail slide seat 13 at the front end of the second electric guide rail 12, an induced draft fan 22 is installed at the front end of the mounting seat 21, and a hose 20 is connected between the mounting seat 21 and the docking box 18;

[0041] Auxiliary heat dissipation mechanism 9, the auxiliary heat dissipation mechanism 9 is assembled inside the installation box 1;

[0042] The auxiliary heat dissipation mechanism 9 includes a manifold 901 mounted above the inside of the installation box 1. The top of the manifold 901 extends out of the installation box 1 and is connected to an exhaust fan 902. The bottom of the manifold 901 is connected to a plurality of solenoid valves 903. The bottom of the solenoid valve 903 is connected to an air duct 904.

[0043] Among them, the temperature detectors 15 are distributed in various parts inside the installation box 1, and the information of the temperature detectors 15 distributed inside the installation box 1 is transmitted to the controller 10 for recording. The controller 10 records the position data of each air duct 904 at the bottom of the manifold 901 inside the installation box 1, and the solenoid valve 903 is in a normally closed state.

[0044] As can be seen from the above, the components related to the SVG device are installed inside the installation box 1. During the operation of the device, the temperature detector 15 is used to detect the temperature of each position inside the installation box 1, and the detected data is transmitted to the inside of the controller 10 for analysis and processing. When the temperature of a certain position inside the installation box 1 is too high, the controller 10 determines the position of the relevant temperature detector 15 inside the installation box 1 and calculates the position of the nearest air duct 904.

[0045] Start the first electric guide rail 11 and the second electric guide rail 12, and the first electric guide rail 11 and the second electric guide rail 12 start to drive the guide rail slide 13 to move at the same time. During the movement of the guide rail slide 13, the infrared rangefinder 24 is used to scan and detect the distance to the mounting seat 21, and the distance is transmitted to the inside of the controller 10 for analysis and processing. The position of the mounting seat 21 is judged by scanning the distance between the infrared rangefinder 24 and the mounting seat 21. When the mounting seat 21 moves to the bottom of the designated air duct 904, the controller 10 stops the operation of the first electric guide rail 11 and the second electric guide rail 12. At this time, the docking box 18 is located below the designated air duct 904. After starting the electric telescopic rod 14, the output end of the electric telescopic rod 14 drives the second electric guide rail 12 to move up and down inside the mounting box 1, so that the induced draft fan 22 can be closer to the heating point;

[0046] The controller 10 starts the electric push rod 16. During the operation of the electric push rod 16, the output end thereof pushes the docking box 18 to move upward. During the upward movement of the docking box 18, the air duct 904 is inserted into the interior of the docking hole 19. After the insertion, the controller 10 opens the corresponding solenoid valve 903, starts the exhaust fan 902 and the induced draft fan 22. During the operation of the exhaust fan 902 and the induced draft fan 22, the hot air inside the installation box 1 is extracted through the manifold 901, the docking box 18 and the hose 20, thereby achieving local heat dissipation.

[0047] By installing an auxiliary heat dissipation mechanism 9, a first electric guide rail 11 and a second electric guide rail 12, during use, the position of the docking box 18 and the mounting seat 21 inside the installation box 1 can be adjusted according to the position of the heat point inside the installation box 1. After starting the exhaust fan 902 and the induced draft fan 22, the interior of the installation box 1 can be cooled, thereby achieving precise positioning of heat dissipation, reducing heat dissipation energy consumption, and optimizing the use process.

[0048] As attached Figure 4 and attached Figure 5 As shown:

[0049] Specifically, regarding the auxiliary heat dissipation mechanism 9 and the docking hole 19, the auxiliary heat dissipation mechanism 9 further includes a pipe rack 905 installed on the periphery of the manifold 901, and the pipe rack 905 is connected to the inner wall of the installation box 1 by bolts 906;

[0050] One end of the docking hole 19 close to the air duct 904 is in a trumpet shape.

[0051] As can be seen from the above, by using bolts 906 to pass through the pipe rack 905 and connect it to the inner wall of the installation box 1, the position of the manifold 901 inside the installation box 1 can be limited when in use, thereby avoiding shaking and displacement of the manifold 901 during use, ensuring the docking between the docking box 18 and the auxiliary heat dissipation mechanism 9, and by designing a trumpet-shaped docking hole 19, the inclined wall can be used to guide the docking of the air duct 904 and the docking box 18 during docking, thereby improving the docking effect of the air duct 904 and the docking box 18.

[0052] As attached Figure 5 As shown:

[0053] Specifically, regarding the first electric guide rail 11 , a slide groove 17 is provided on the surface of the guide rail slide seat 13 at the front end of the first electric guide rail 11 , and a slider matched with the slide groove 17 is installed at the rear end of the docking box 18 .

[0054] The vertical surface of the slide groove 17 and the slide block is in a T-shaped structure.

[0055] As can be seen from the above, when the docking box 18 moves up and down driven by the electric push rod 16, it will drive the slider to move simultaneously inside the slide groove 17, thereby connecting the docking box 18 and the guide rail slide 13, making the movement of the docking box 18 smoother and improving the accuracy of the docking between the docking box 18 and the auxiliary heat dissipation mechanism 9.

[0056] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 and attached Figure 6 As shown:

[0057] Specifically, regarding the above-mentioned installation box 1 and filter mechanism 3, an air inlet window 2 is provided on the side of the installation box 1, and a filter mechanism 3 corresponding to the position of the air inlet window 2 is installed on the inner wall of the installation box 1;

[0058] The filter mechanism 3 comprises a filter box 301 installed on the inner wall of the installation box 1 , an ash filter net 302 is installed inside the filter box 301 , and a primary filter net 303 is installed on one side of the ash filter net 302 .

[0059] Among them, a plurality of shutters are installed inside the air inlet window 2.

[0060] As can be seen from the above, during the operation of the auxiliary heat dissipation mechanism 9, negative pressure is generated inside the installation box 1, and the gas around the device enters the installation box 1 through the air inlet window 2. The louvers are used to guide the rainwater, and the primary filter net 303 inside the filtering mechanism 3 is used to intercept large floating objects and flying insects mixed in the air. The primary filter net 303 is used to filter the dust carried in the air to prevent dust from entering the interior of the installation box 1 and causing damage to components.

[0061] As attached Figure 1 , Attachment Figure 2 and attached Figure 3 As shown:

[0062] Specifically, regarding the above-mentioned installation box 1, a plurality of installation racks 23 are installed inside the installation box 1, and installation holes are opened on the installation racks 23;

[0063] An inspection door 5 is rotatably mounted on the front end of the installation box 1 , and a base 4 is mounted on the bottom of the installation box 1 .

[0064] As can be seen from the above, the mounting frame 23 can provide an installation structure for related components according to the assembly requirements of the SVG device when in use, so that users can assemble the components. The inspection door 5 can facilitate users to inspect and assemble the components inside the installation box 1 when in use. The base 4 can maintain a certain height between the bottom of the installation box 1 and the ground when in use, thereby improving the moisture-proof performance of the device.

[0065] The working principle of this embodiment is as follows: the components related to the SVG device are installed inside the installation box 1. During the operation of the device, the temperature of each position inside the installation box 1 is detected by the temperature detector 15, and the detected data is transmitted to the inside of the controller 10 for analysis and processing. When the temperature of a certain position inside the installation box 1 is too high, the controller 10 determines the position of the relevant temperature detector 15 inside the installation box 1 and calculates the position of the nearest air duct 904.

[0066] Start the first electric guide rail 11 and the second electric guide rail 12, and the first electric guide rail 11 and the second electric guide rail 12 start to drive the guide rail slide 13 to move at the same time. During the movement of the guide rail slide 13, the infrared rangefinder 24 is used to scan and detect the distance to the mounting seat 21, and the distance is transmitted to the inside of the controller 10 for analysis and processing. The position of the mounting seat 21 is judged by scanning the distance between the infrared rangefinder 24 and the mounting seat 21. When the mounting seat 21 moves to the bottom of the designated air duct 904, the controller 10 stops the operation of the first electric guide rail 11 and the second electric guide rail 12. At this time, the docking box 18 is located below the designated air duct 904. After starting the electric telescopic rod 14, the output end of the electric telescopic rod 14 drives the second electric guide rail 12 to move up and down inside the mounting box 1, so that the induced draft fan 22 can be closer to the heating point;

[0067] The controller 10 starts the electric push rod 16. During the operation of the electric push rod 16, its output end pushes the docking box 18 to move upward. During the upward movement of the docking box 18, the air duct 904 is inserted into the docking hole 19. After the insertion, the controller 10 opens the corresponding solenoid valve 903, starts the exhaust fan 902 and the induced draft fan 22. During the operation of the exhaust fan 902 and the induced draft fan 22, the hot air inside the installation box 1 is extracted through the manifold 901, the docking box 18 and the hose 20.

[0068] Negative pressure is generated inside the installation box 1, and the gas around the device enters the installation box 1 through the air inlet window 2. The louvers are used to guide rainwater, and the primary filter net 303 inside the filtering mechanism 3 intercepts large floating objects and flying insects mixed in the air. The primary filter net 303 is used to filter the dust carried in the air, thereby completing the heat dissipation.

[0069] As attached Figure 1 , Attachment Figure 2 and attached Figure 3 As shown:

[0070] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that:

[0071] A heat dissipation fan row 8 is installed on the top of the installation box 1, and a through hole adapted to the heat dissipation fan row 8 is opened on the top of the installation box 1;

[0072] A bracket 7 is installed on the top of the installation box 1 , and a protective cover 6 is installed on the top of the bracket 7 . The protective cover 6 is sleeved on the periphery of the heat dissipation fan row 8 , and ventilation slots are opened on the protective cover 6 .

[0073] The heat dissipation fan row 8 is electrically connected to the controller 10 , and the exhaust fan 902 is located inside the protective cover 6 .

[0074] As can be seen from the above, multiple temperature detectors 15 distributed inside the installation box 1 detect the temperature and transmit the detected signals to the inside of the controller 10 for analysis and processing. When the controller 10 analyzes that the temperatures detected by the temperature detectors 15 at multiple locations are too high, the controller 10 starts the heat dissipation fan row 8. During the operation of the heat dissipation fan row 8, multiple fans are used to run simultaneously to extract the gas inside the installation box 1. After the gas is extracted, negative pressure is generated inside the installation box 1, so that the gas outside the installation box 1 enters the inside of the installation box 1 through the air inlet window 2, thereby realizing rapid heat exchange inside the installation box 1 and improving the heat dissipation effect of the device.

[0075] The protective cover 6 is assembled on the top of the installation box 1 through the bracket 7, and the protective cover 6 is used to wrap and protect the cooling fan row 8 and the exhaust fan 902 to prevent rain and dust from entering the interior of the device through the cooling fan row 8 and the exhaust fan 902. The ventilation slots on the protective cover 6 can discharge the hot air emitted by the cooling fan row 8 and the exhaust fan 902, thereby completing the heat dissipation.
