Description

Technical Field

[0001] The utility model relates to the technical field of frequency conversion control, in particular to a frequency conversion temperature reduction control device for SVG. Background Art

[0002] As a modern reactive power compensation device, SVG (Static Var Generator) plays an important role in the power system. However, SVG generates a lot of heat during operation. If the heat cannot be dissipated in a timely and effective manner, the temperature of SVG will rise, which will affect its performance and life. Traditional cooling methods usually use fixed fan speed and cooling medium flow, which cannot be intelligently adjusted according to the actual temperature of SVG, so the cooling effect is not ideal.

[0003] After searching, the Chinese patent document application number: 202120111003.8 discloses a high-voltage SVG air-cooled heat dissipation system frequency conversion controller, including a controller body, a groove body is opened at the top and bottom of the controller body, a sliding rod is bolted between the two sides of the inner wall of the groove body, and sliders are slidably connected on both sides of the surface of the sliding rod; the utility model starts the exhaust fan, and the exhaust fan drives the heat generated by the internal operation of the controller body to be discharged from the heat dissipation port, so as to cool down and dissipate the heat of the controller body, thereby reducing the poor heat dissipation effect, which may easily cause damage to electronic components and other faults, and at the same time, for precision instruments that are easily damaged after collision, the heat dissipation effect is improved; the utility model drives the combination rod to extend and retract through the protective plate, so that the slider slides on the surface of the slide rod to squeeze the reset spring, and the movable plate squeezes the spring damper for energy absorption protection, thereby protecting the internal components, having the effect of buffering energy absorption, and improving the collision resistance of the device.

[0004] However, the above-mentioned high-voltage SVG air-cooling heat dissipation system variable frequency controller still has the following defects:

[0005] The above-mentioned high-voltage SVG air-cooled heat dissipation system variable frequency controller starts the exhaust fan, and the exhaust fan drives the heat generated by the internal operation of the controller body to be discharged from the heat dissipation port, thereby cooling the controller body and reducing the poor heat dissipation effect, which may easily lead to failures such as damage to electronic components. At the same time, it improves the heat dissipation effect for precision instruments that are easily damaged after collision. However, the variable frequency controller only dissipates heat through the exhaust fan. When the temperature is high, the fixed fan speed may not provide sufficient heat dissipation capacity; when the temperature is low, unnecessary energy consumption may be generated. Therefore, we need a variable frequency cooling control device for SVG to solve the above problems. Utility Model Content

The wind flow generated by this rotation passes through the heat dissipation holes, takes away the heat inside the controller body, and effectively reduces the internal temperature. The setting of the filter cotton effectively prevents the entry of impurities such as dust, ensures the smooth flow of the heat dissipation holes, and further enhances the heat dissipation effect. When the temperature drops, the control panel can reduce the speed of the drive motor or stop working completely according to the real-time feedback of the temperature sensor, thereby reducing unnecessary energy consumption.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] When in use, after receiving the instruction from the control panel 26, the drive motor 20 in the heat dissipation component will start quickly, driving the fan blades 22 to rotate at high speed. The wind flow generated by this rotation passes through the heat dissipation holes 10, takes away the heat inside the controller body 1, and effectively reduces the internal temperature. The setting of the filter cotton 9 effectively prevents the entry of dust and other impurities, ensures the smooth flow of the heat dissipation holes 10, and further enhances the heat dissipation effect. The setting of the steam-water separator body 13 can effectively separate the steam-water mixture generated during the cooling process, avoiding potential damage to the interior of the equipment by moisture, and also ensures the stability of the heat dissipation effect. When the temperature drops, the control panel 26 can reduce the speed of the drive motor 20 or stop working completely according to the real-time feedback of the temperature sensor, thereby reducing unnecessary energy consumption.

[0025] A second heat dissipation window 27 is provided on the other side of the controller body 1, and electrostatic dust collecting chambers 4 are arranged on both sides of the controller body 1. A support plate 2 is fixedly installed at one end of the electrostatic dust collecting chamber 4, and one side of the support plate 2 is fixedly connected to the side of the controller body 1, and a through hole is provided on the outer side of the electrostatic dust collecting chamber 4, and a filter net 5 is laid on the surface of the through hole. The opening of the second heat dissipation window 27 further enhances the heat dissipation effect. The electrostatic dust collecting chamber 4 utilizes the principle of static electricity to efficiently adsorb and collect dust particles in the air. When the wind flows through the electrostatic dust collecting chamber 4, the dust particles will be electrostatically adsorbed on the inner wall of the dust collecting chamber or the collection plate, thereby effectively purifying the air entering the controller body 1. This design not only extends the service life of the filter cotton 9 and reduces the replacement frequency, but also reduces the potential risk of damage to the internal components of the equipment by dust.

[0026] An electrostatic dust collector seat 3 is embedded in the front opening of the electrostatic dust collector chamber 4, and a plurality of equidistant electrostatic dust collector plates 6 are fixedly installed inside the electrostatic dust collector seat 3. Since the electrostatic dust collector plates 6 have a large surface area and good conductive properties, they can efficiently collect dust in the air, thereby achieving air purification.

[0027] A screw hole seat 7 which is symmetrical up and down is provided at the front opening of the electrostatic dust collecting chamber 4, and a bolt 8 which is matched with the screw hole seat 7 is provided on the front side of the electrostatic dust collector seat 3. Through the matching connection between the bolt 8 and the screw hole seat 7, the installation and disassembly of the electrostatic dust collector seat 3 becomes simple and quick.

An exhaust duct 14 is installed on the other side of the upper end of the steam-water separator body 13. A first heat dissipation window 12 is opened on the other side of the heat dissipation box 11. The air outlet of the exhaust duct 14 is tightly connected to one side of the first heat dissipation window 12. Fresh air is inhaled through the ventilator 15 and hot air is discharged from the exhaust duct 14, thereby realizing effective transfer and dissipation of heat. The exhaust duct 14 can quickly discharge the hot air generated inside the steam-water separator, and the first heat dissipation window 12 provides additional heat dissipation area, further accelerating the dissipation of heat.

[0029] A first grille baffle 17 is provided inside the steam-water separator body 13, an adsorption pad 18 is provided below the first grille baffle 17, and a second grille baffle 19 is installed below the adsorption pad 18. The other end of the ventilator 15 passes through the bottom ends of the first grille baffle 17, the adsorption pad 18 and the second grille baffle 19 and extends to the outside of the bottom end of the steam-water separator body 13. The first grille baffle 17 and the second grille baffle 19 can effectively divide the internal space of the steam-water separator body 13, so that the flow rate and direction of the steam and water can change when flowing through these baffles, which is beneficial to the preliminary separation of the steam-water mixture. The adsorption pad 18 is usually made of a material with strong adsorption capacity, which can effectively remove tiny particles and bad odors in the steam and water, thereby improving the quality of the separated steam and water.

[0030] A through groove is provided inside the stabilizing block 24, and a water collecting tank 25 is arranged inside the through groove. A water collecting port 23 is provided at the bottom end of the steam-water separator. The bottom end of the water collecting port 23 passes through the stabilizing block 24 and extends to the top of the water collecting tank 25. A handle is installed on one side of the water collecting tank 25. Condensed water can be conveniently collected, stored and processed through the water collecting tank 25, avoiding environmental pollution problems that may be caused by the arbitrary discharge of condensed water.
