Description

Technical Field

[0001] The present invention relates to the technical field of capacitors, and in particular to an intelligent capacitor. Background Art

[0002] Two conductors close to each other with a layer of non-conductive insulating medium in between constitute a capacitor. When voltage is applied between the two plates of the capacitor, the capacitor will store charge. The capacitance of the capacitor is numerically equal to the ratio of the charge on one conductive plate to the voltage between the two plates. The basic unit of the capacitance of the capacitor is farad. The letter C is usually used to represent the capacitor element in the circuit diagram.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0025] Example 1

[0026] Reference Figure 1-Figure 4, an intelligent capacitor, including a shell 1 and a power capacitor 3 and a filter reactor 4 installed in the shell 1, the power capacitor 3 is used to store and release electric energy, the filter reactor 4 is used to smooth current fluctuations and reduce harmonics, the shell 1 is fixedly connected with an upper chassis 11, the outer wall of the upper chassis 11 is provided with an intelligent measurement and control module 13, which is used to monitor and adjust the operating state of the capacitor, and the upper chassis 11 is provided with a circuit breaker 12 to provide circuit protection, and also includes: a heat-conducting base 31 fixedly connected to the shell 1, and the heat generated by the capacitor during operation can be quickly conducted out through the heat-conducting base 31, wherein the power capacitor 3 is fixedly connected to the heat-conducting base 31, and the upper and lower ends of the power capacitor 3 are provided with the heat-conducting base 31, thereby ensuring a full range of heat dissipation effects, and a mounting seat 41 fixedly connected to the shell 1, wherein a heat-conducting bottom plate 42 is fixedly connected to the mounting seat 41, so that the reactor can also effectively dissipate heat through the heat-conducting bottom plate 42 during operation, and both ends of the filter reactor 4 are provided with heat-conducting The bottom plate 42 and the mounting seat 41 further improve the heat dissipation effect, and are fixedly connected to the heat dissipation box 6 in the shell 1, wherein a plurality of fans 21 are arranged at both ends of the heat dissipation box 6, specifically 6 groups of fans 21, and 3 groups of fans 21 are arranged in the upper and lower cavities of the heat dissipation box 6, and the fan 21 at one end is an air inlet fan 21 for inhaling external cold air, and the fan 21 at one end is an exhaust fan 21 for discharging hot air out of the capacitor, forming an effective air convection system, further improving the heat dissipation effect, and a double-headed connecting plate 52 is slidably mounted on the heat-conducting bottom plate 42 and the heat-conducting base 31, wherein a heat-conducting plug-in plate 55 is fixedly connected to the double-headed connecting plate 52, and the heat-conducting plug-in plate 55 is slidably mounted inside the heat dissipation box 6, and a transverse partition and a longitudinal partition are arranged inside the heat dissipation box 6, and the heat dissipation box 6 is divided into 4 cavities and separates the 4 heat-conducting plug-in plates 55, this design not only improves the structural strength and heat insulation capacity of the heat dissipation box 6, but also enables the four heat-conducting plug-in plates 55 to effectively dissipate heat in these cavities respectively.

[0027] When the smart capacitor is in use, the power capacitor 3 and the filter reactor 4 inside the shell 1 work simultaneously. The power capacitor 3 is responsible for storing and releasing electric energy, while the filter reactor 4 is used to reduce high-frequency noise in the current to ensure the quality of electric energy. The shell 1 not only provides protection for internal components, but also promotes heat dissipation through its design to maintain the equipment running at a safe temperature. In addition, the structural design of the shell 1 also takes electromagnetic compatibility into consideration to reduce electromagnetic interference to the external environment when the equipment is running.

[0028] When the power capacitor 3 and the filter reactor 4 inside the shell 1 are cooled, the heat is transferred through the heat-conducting plug plate 55 and slides inside the heat-dissipating box 6. The heat-conducting plug plate 55 can fully exchange heat with the air in the heat-dissipating box 6, so as to effectively dissipate the heat. Since the heat-dissipating box 6 is provided with a transverse partition and a longitudinal partition, this not only increases the structural strength of the heat-dissipating box 6, but also improves its thermal insulation performance, ensuring that the heat-conducting plug plate 55 can efficiently dissipate heat in each cavity. In addition, fans 21 are provided at both ends of the heat-dissipating box 6 to form air convection, further enhancing the heat dissipation effect. The fan 21 includes not only an air inlet fan 21 but also an exhaust fan 21, which work together to discharge hot air and inhale cold air to maintain the temperature balance inside the capacitor. Through such a heat dissipation design, the intelligent capacitor can operate stably for a long time to avoid performance degradation or damage caused by overheating. At the same time, it avoids direct blowing of the fan 21 on the power capacitor 3 and the filter reactor 4, thereby reducing the erosion of dust and moisture on the equipment and extending the service life of the power capacitor 3 and the filter reactor 4. In addition, through the setting of the heat conductive base plate 42 and the heat conductive base 31, it is ensured that the heat generated by the power capacitor 3 and the filter reactor 4 during operation can be quickly conducted and dissipated, thereby improving the heat dissipation efficiency and stability of the entire system.

[0029] Both sides of the heat-conducting bottom plate 42 are configured to be toothed plates, thereby facilitating the passage of electrical wires and increasing the surface area of ​​the heat dissipation plate, further enhancing the heat dissipation effect.

[0030] Reference Figure 2-Figure 3 , the heat-conducting bottom plate 42 and the heat-conducting base 31 are fixedly connected with a heat-conducting plate 5, and the heat-conducting plate 5 is fixedly connected with a memory metal 51, also known as a shape memory alloy, specifically a spring-shaped metal made of nickel-titanium alloy. In this embodiment, the memory metal 51 is deformed above 45°, and the free end of the memory metal 51 is fixedly connected to the double-headed connecting plate 52. The memory metal 51 is used to adjust its shape in response to temperature changes, thereby driving the double-headed connecting plate 52 and the heat-conducting plug plate 55 to slide in the heat dissipation box 6, increasing the volume of the heat-conducting plug plate 55 in the heat dissipation box 6 to adapt to different heat dissipation requirements. The shell 1 is provided with ventilation channels at both ends of the heat dissipation box 6, and the fan 21 is arranged in the ventilation channel to ensure that the air can flow smoothly through the heat dissipation box and effectively take away the heat. The shell 1 is slidably installed with a filter 2 on both sides of the fan 21. The function of the filter 2 is to prevent dust and other impurities from entering the capacitor, thereby protecting the internal components from pollution and damage. The filter 2 can also reduce the noise when the fan 21 is running and prevent the blades of the fan 21 from being damaged by impurities.

[0031] When the operating temperature of the capacitor increases, the memory metal 51 will deform due to the temperature rise, thereby pushing the double-headed connecting plate 52 and the heat-conducting plug plate 55 to slide toward the inside of the heat dissipation box 6 to increase the heat dissipation area; conversely, when the temperature drops, the memory metal 51 returns to its original state, and the heat-conducting plug plate 55 correspondingly slides toward the outside of the heat dissipation box 6 to reduce the heat dissipation area. This adaptive heat dissipation mechanism can ensure that the capacitor can maintain the best heat dissipation effect under different working conditions.

[0032] Example 2

[0033] The embodiment is basically the same as the first embodiment, and further, a specific implementation scheme for fire extinguishing when the temperature inside the shell 1 is overheated, ignites, or explodes is specifically added.

[0034] Reference Figure 3-Figure 6 The cavity of the heat dissipation box 6 is fixedly connected with a perfluorohexanone fire extinguishing airbag 7, and the free end of the perfluorohexanone fire extinguishing airbag 7 is fixedly connected with a push rod 71, and the push rod 71 is against the heat conductive plug plate 55. When the temperature is too high, the memory metal 51 is deformed and drives the heat conductive plug plate 55 to slide, and the heat conductive plug plate 55 pushes the push rod 71 to move synchronously, thereby compressing the perfluorohexanone fire extinguishing airbag 7 inside the heat dissipation box 6. The outer walls on both sides of the heat dissipation box 6 are fixedly connected with expansion airbags 77. The expansion airbags 77 on each side are connected to the two perfluorohexanone fire extinguishing airbags 7 of the longitudinal partition in the heat dissipation box 6 through a connecting pipe 76. When the perfluorohexanone fire extinguishing airbag 7 is squeezed, the expansion airbag 77 will expand.

[0035] When the temperature inside the capacitor is too high, the perfluorohexanone in the perfluorohexanone fire extinguishing airbag 7 is transferred to the adjacent expansion airbag 77 through the connecting pipe 76. After the expansion airbags 77 on both sides expand, they fit the power capacitor 3 and the filter reactor 4 respectively. When the temperature is too high or there is a fire source, the expansion airbag 77 will quickly release the fire extinguishing agent, covering the surface of the power capacitor 3 and the filter reactor 4, thereby achieving the effect of extinguishing the fire. Perfluorohexanone is a clean fire extinguishing agent, which is environmentally friendly and will not cause damage to the electronic components inside the capacitor. In addition, the use of the perfluorohexanone fire extinguishing airbag 7 can effectively prevent the spread of fire and protect the safety of the entire capacitor equipment.

[0036] Example 3

[0037] The embodiment is basically the same as the second embodiment, and further, a specific implementation scheme for vibration cleaning of the filter screen 2 is specifically added.

[0038] Reference Figure 2-Figure 9, both ends of the push rod 71 are rotatably installed with a rotating shaft 72, and a slider 74 is rotatably installed on the rotating shaft 72. A slide groove 62 is opened in the housing 1, and the slider 74 is slidably installed in the slide groove 62, ensuring that the push rod 71 can maintain a stable trajectory when moving. Among them, both sides of the cavity of the heat dissipation box 6 are fixedly connected with a rack 61, and a travel gear 73 is fixedly connected to the rotating shaft 72. The travel gear 73 is meshed with the rack 61. When the push rod 71 moves, the travel gear 73 will roll along the rack 61, thereby driving the rotating shaft 72 to rotate. The rotating shaft 72 is fixedly connected with a cam 75, the cam 75 cooperates with the filter 2. When the rotating shaft 72 rotates, the cam 75 will repeatedly squeeze the filter 2, causing the filter 2 to slide back and forth. The filter 2 is fixedly connected with a plug rod 57, and the plug rod 57 is slidably installed in the shell 1. A return spring 58 is sleeved on the plug rod 57. The return spring 58 is against the inner wall of the shell 1, allowing the filter 2 to move to one side when squeezed by the cam 75, and to return to the original position through the elastic force of the return spring 58 after the cam 75 passes, and the recovery speed of the filter 2 is increased, so that the vibration cleaning effect on the filter 2 is more significant.

[0039] In this way, the filter 2 can effectively remove dust and impurities attached to the surface and keep the inside of the capacitor clean, thereby extending the service life of the capacitor and ensuring its stable operation. In addition, the vibration cleaning mechanism of the filter 2 can also reduce maintenance costs and labor intensity, because there is no need to frequently manually clean the filter 2, thereby improving the maintenance efficiency of the capacitor.

[0040] Example 4

[0041] The embodiment is basically the same as the third embodiment, and further, a specific implementation scheme of brushing the surface of the filter screen 2 is specifically added.

[0042] Reference Figure 2-Figure 12The L-shaped part of the double-headed connecting plate 52 passes through and slides on the shell 1. The double-headed connecting plate 52 can slide along the track in the shell 1 when subjected to external force. A brush plate 53 is slidably installed on the L-shaped end of the double-headed connecting plate 52. The brush plate 53 is slidably installed on the outer wall of the filter screen 2, which not only ensures that the brush plate 53 can closely fit the filter screen 2 for cleaning, but also allows the brush plate 53 to reciprocate on the surface of the filter screen 2. Brush bristles 56 are fixedly connected to the brush plate 53. The brush bristles 56 are arranged in a close fit with the filter screen 2 to ensure that the brush bristles 56 can penetrate into the pores of the filter screen 2 and effectively remove dust and impurities attached to the filter screen 2. At the same time, due to the soft texture of the brush bristles 56, when the filter screen 2 vibrates, the brush bristles 56 will not affect it. Among them, the L-shaped end of the double-headed connecting plate 52 is provided with a swing groove 59, and a guide rod 510 is fixedly connected to the swing groove 59. A swing slide plate 511 is fixedly connected to the brush plate 53. 511 is slidably installed on the guide rod 510, allowing the brush plate 53 to swing on the guide rod 510. A swing spring 512 is mounted on the guide rod 510, and the swing spring 512 is against the swing slide plate 511, providing a certain restoring force and stability for the brush plate 53. When the brush plate 53 is subjected to external force, the swing spring 512 can absorb the impact force and restore the brush plate 53 to its original position through its restoring force, thereby ensuring a continuous cleaning effect. Guide heads 54 are fixedly connected to both ends of the brush plate 53, and corrugated tooth plates 22 are fixedly connected to both ends of the outer wall of the filter screen 2, and the protrusions of the corrugated tooth plates 22 at both ends are staggered. The guide heads 54 cooperate with the corrugated tooth plates 22 at both ends. When the brush plate 53 slides on the surface of the filter screen 2, the guide heads 54 will reciprocate along the protrusions and depressions of the corrugated tooth plates 22. This movement mode helps the bristles 56 to clean the pores of the filter screen 2 more deeply.

[0043] In the present invention, first, under the normal working state of the intelligent capacitor, the temperature of the power capacitor 3 and the filter reactor 4 is maintained within a safe range, and the memory metal 51 will not be deformed, so the double-headed connecting plate 52 and the heat-conducting plug plate 55 remain in the initial position, and will not affect the internal structure of the heat dissipation box 6. When the internal temperature of the capacitor rises and the memory metal 51 reaches its deformation temperature threshold, the memory metal 51 begins to deform, pushing the double-headed connecting plate 52 and the heat-conducting plug plate 55 to slide toward the inside of the heat dissipation box 6, thereby increasing the heat dissipation area to adapt to the increase in heat dissipation demand. This design ensures that the capacitor can maintain the best heat dissipation effect under different working conditions, avoiding performance degradation or damage caused by overheating.

[0044] When the temperature inside the capacitor is too high or a fire occurs, the perfluorohexanone fire extinguishing airbag 7 is compressed and the perfluorohexanone is introduced into the expansion airbag 77. When the temperature is too high and there is a risk of fire or there is a fire source, the fire extinguishing agent is quickly released to cover the surface of the power capacitor 3 and the filter inductor 4 to achieve a fire extinguishing effect. The expansion of the expansion airbag 77 further ensures that the fire extinguishing agent can effectively cover the key components of the capacitor, prevent the fire from spreading, and protect the safety of the entire capacitor equipment.

[0045] When the temperature rises and the heat conductive plug plate 55 moves, the filter 2 vibrates through the cooperation of the cam 75. The vibration cleaning mechanism of the filter 2 makes the filter 2 slide back and forth through the repeated squeezing of the cam 75. The reciprocating motion of the bristles 56 can effectively remove dust and impurities on the surface of the filter 2, prevent the excessive temperature caused by excessive dust on the surface of the filter 2 affecting the heat dissipation effect, extend the service life of the capacitor and ensure its stable operation. The swinging motion of the brush plate 53 and the cooperation of the guide head 54 with the corrugated tooth plate 22 further enhance the cleaning effect of the bristles 56 on the pores of the filter 2, ensuring the cleaning efficiency and effect of the filter 2.

[0046] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
