Description

Technical Field

[0001] The present invention relates to the technical field of power distribution cabinet control, and in particular to an intelligent low-voltage power distribution cabinet power distribution control system. Background Art

[0002] Low-voltage distribution cabinets are inevitably disturbed by dust in daily work. Because dust is conductive, when there is too much dust in the distribution cabinet, it is easy to cause the insulation performance of the equipment to decline, thereby increasing the risk of short circuit. At the same time, dust will affect the heat dissipation effect of the distribution cabinet, causing the equipment to overheat and affect the normal operation of the equipment. In severe cases, it may even cause a fire. Therefore, in order to reduce the interference of dust on the low-voltage distribution cabinet, an intelligent low-voltage distribution cabinet power distribution control system is selected to reduce the dust accumulation inside the low-voltage distribution cabinet.

[0003] How to avoid circuit failure caused by excessive dust accumulation is the top priority for ensuring the normal operation of low-voltage distribution cabinets. For example, a waterproof and dustproof distribution cabinet is disclosed in the prior art, including a cabinet body, characterized in that the distribution cabinet also includes a heat dissipation mechanism, the heat dissipation mechanism includes a heat dissipation fan, a heat dissipation hole is opened at the side end of the cabinet body, the heat dissipation fan is arranged in the heat dissipation hole, and a filter cotton plate is installed at the inner end of the heat dissipation hole, and the filter cotton plate is used to filter water vapor and dust in the air entering the cabinet body; the distribution cabinet also includes a cleaning component and a cleaning drive component, the cleaning drive component is arranged in the cabinet body, the cleaning component and the cleaning drive component are connected in transmission, the cleaning component includes a scraper, the scraper is located at the outer end of the heat dissipation hole, and the scraping end of the scraper is frictionally opposed to the outer wall of the cabinet body; under the transmission of the cleaning drive component, when the scraper is located at the cleaning position, the scraping end of the scraper is frictionally opposed to the outer wall of the cabinet body, and the scraper is moved from the lower position of the heat dissipation hole to the upper position of the heat dissipation hole; when the scraper is located at the transposition position, the scraping end of the scraper is spaced from the outer wall of the cabinet body.

[0004] However, in the technical solution of the above-mentioned waterproof and dustproof distribution cabinet, the collected data cannot effectively determine the dust accumulation in the internal wiring area of ​​the low-voltage distribution cabinet, and further cannot determine whether there is dust interfering with the operation of the internal wiring area, which has limitations on the dust protection of the low-voltage distribution cabinet. Summary of the invention

[0005] The purpose of the present invention is to provide an intelligent low-voltage distribution cabinet power distribution control system to solve the problem in the related art that the collected data cannot effectively determine the dust accumulation in the internal wiring area of ​​the low-voltage distribution cabinet, and further cannot determine whether there is dust interfering with the operation of the internal wiring area, which has limitations on the dust protection of the low-voltage distribution cabinet.

[0006] To this end, the present invention provides an intelligent low-voltage distribution cabinet power distribution control system, comprising: A detection module, which is used to obtain the dust accumulation degree of the low-voltage distribution cabinet; A determination module, connected to the detection module, for comparing the dust accumulation degree with a corresponding standard accumulation degree, and determining whether to clean the low-voltage distribution cabinet according to the comparison result; A cleaning module, connected to the determination module, for responding to the determination module's cleaning instruction to the low-voltage power distribution cabinet to reduce the dust accumulation degree; A storage module, which is connected to the detection module and is used to store the dust growth of the low-voltage power distribution cabinet after cleaning in different time periods and through the same collection cycle; A dust reduction module, which is connected to the storage module and is used to analyze the change trend of the dust growth amount and determine whether to reverse the heat dissipation angle of the low-voltage power distribution cabinet; Wherein, the heat dissipation angle is the acute angle between the shutter-type heat dissipation baffle provided on the low-voltage power distribution cabinet and the vertical direction; The dust accumulation degree is the average dust thickness of several detection areas of the low-voltage distribution cabinet on the same plane; The dust growth amount is the change in average dust thickness of several detection areas of the low-voltage distribution cabinet that are located in the same plane.

[0007] The detection module uses a light scattering method to obtain the dust accumulation degree of the low-voltage distribution cabinet by means of a plurality of light source transmitters and a plurality of reflected light receivers arranged in the low-voltage distribution cabinet.

[0008] The plurality of detection areas are arranged on the internal wiring surface of the low-voltage distribution cabinet.

[0009] The determination module compares the dust accumulation degree obtained by the detection module with the standard accumulation degree; Wherein, if the dust accumulation degree is greater than the standard accumulation degree, the determination module sends the cleaning instruction to the cleaning module; If the dust accumulation degree is less than the standard accumulation degree, the determination module remains silent; Among them, the standard accumulation degree is related to the output voltage of the low-voltage distribution cabinet.

[0010] The cleaning module includes a plurality of brushes arranged in parallel opposite to each other; When the cleaning module responds to the cleaning instruction, the brush cleans the plane of the detection area where the dust accumulation degree is greater than the standard accumulation degree until the dust accumulation degree is less than the standard accumulation degree.

[0011] The detection module performs a secondary detection on the detection area after cleaning, specifically, the detection module obtains the dust growth amount of several detection areas in any plane after cleaning in different time periods and through the same collection cycle.

[0012] The low-voltage power distribution cabinet comprises a plurality of heat dissipation holes, and a single heat dissipation hole is composed of a plurality of the louver-type heat dissipation baffles.

[0013] The dust reduction module includes an analysis component and a torsion component; The analysis component is used to analyze the change trend of the dust growth amount, specifically, to compare the dust growth amount in different time periods with their corresponding standard growth amounts; Wherein, if the dust growth amount>the standard growth amount, the analysis component sends a dust reduction signal; If the dust growth amount is less than the standard growth amount, the analysis component remains silent.

[0014] When the dust growth amount on any plane of the low-voltage power distribution cabinet at different time periods is greater than the standard growth amount, the torsion component twists the plurality of heat dissipation baffles in the heat dissipation holes with the smallest horizontal distance from any plane to reduce the heat dissipation angle.

[0015] The torsion component responds to the dust reduction signal sent by the analysis component, specifically, the torsion component twists the plurality of heat dissipation baffles in the same heat dissipation hole in the same direction and angle.

[0016] The beneficial effects of the present invention are: The present invention provides an intelligent low-voltage distribution cabinet power distribution control system, which can continuously and in real time monitor the dust accumulation degree inside the low-voltage distribution cabinet by integrating high-precision sensors. Once it is detected that the dust accumulation reaches a preset critical value, the system will automatically trigger a cleaning program, and use advanced dust suction or purging technology to efficiently and thoroughly remove the dust in the cabinet, prevent dust from corroding the precision electronic components and electrical connection points inside the distribution cabinet, significantly extend the service life of the equipment, reduce the failure rate caused by dust, realize intelligent control of the low-voltage distribution cabinet, improve the overall operating efficiency and stability, and thus greatly improve the reliability and stability of the power distribution control system for dust protection of the low-voltage distribution cabinet.

[0017] Furthermore, the system's built-in judgment module uses advanced algorithms to accurately compare the current dust accumulation with the preset standard accumulation threshold. When it detects that the dust accumulation exceeds the safe range, the module will automatically make a cleaning decision and immediately start the cleaning procedure; conversely, if the dust volume is below the safe level, no cleaning will be performed, thereby avoiding excessive or unnecessary cleaning operations, saving precious energy resources, reducing manual intervention in the maintenance process, and greatly improving operation and maintenance efficiency, thereby greatly improving the reliability and stability of the power distribution control system for dust protection of low-voltage distribution air and low-voltage distribution cabinets.

[0018] Furthermore, in order to further optimize the working environment of the low-voltage distribution cabinet, the dust reduction module also has an innovative function - dynamic adjustment of the heat dissipation angle. By analyzing the changing trend of dust growth over a period of time, the module can intelligently predict the possible situation of dust accumulation in the future, and automatically adjust the heat dissipation angle of the distribution cabinet to the optimal state accordingly. This dynamic adjustment strategy not only ensures that the distribution cabinet dissipates heat efficiently, but also effectively prevents excessive accumulation of dust, ensuring that the distribution cabinet can operate stably in the best state under various working conditions, improving the reliability and safety of the system, and thus greatly improving the reliability and stability of the distribution control system for the dust protection of the low-voltage distribution air to the low-voltage distribution cabinet.

[0019] Furthermore, the present invention has better analyzability for the division of detection areas. The division is based on the closed area on the internal wiring surface of the low-voltage distribution cabinet in the same horizontal plane. The detection area divided in this way can effectively characterize the differences in dust accumulation degrees of internal wiring in different planes, so as to facilitate further analysis.

DETAILED DESCRIPTION

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.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0024] Low-voltage distribution cabinets are inevitably disturbed by dust in daily work. Because dust is conductive, when there is too much dust in the distribution cabinet, it is easy to cause the insulation performance of the equipment to decline, thereby increasing the risk of short circuit. At the same time, dust will affect the heat dissipation effect of the distribution cabinet, causing the equipment to overheat and affect the normal operation of the equipment. In severe cases, it may even cause a fire. Therefore, in order to reduce the interference of dust on the low-voltage distribution cabinet, an intelligent low-voltage distribution cabinet power distribution control system is selected to reduce the dust accumulation inside the low-voltage distribution cabinet.

[0025] See also Figure 1 As shown, the intelligent low-voltage power distribution cabinet power distribution control system provided by the present invention includes: A detection module, which is used to obtain the dust accumulation degree of the low-voltage distribution cabinet; A determination module, which is connected to the detection module and is used to compare the dust accumulation degree with the corresponding standard accumulation degree, and determine whether to clean the low-voltage distribution cabinet according to the comparison result; A cleaning module, which is connected to the determination module and is used to respond to the determination module's cleaning instruction to the low-voltage distribution cabinet to reduce dust accumulation; A storage module, which is connected to the detection module and is used to store the dust growth of the cleaned low-voltage distribution cabinet in different time periods after the same collection cycle; A dust reduction module, which is connected to the storage module and is used to analyze the change trend of dust growth and determine whether to reverse the heat dissipation angle of the low-voltage distribution cabinet; The heat dissipation angle is the acute angle between the shutter-type heat dissipation baffle provided on the low-voltage power distribution cabinet and the vertical direction; The dust accumulation degree is the average dust thickness of several detection areas of the low-voltage distribution cabinet on the same plane; The dust growth amount is the change in the average dust thickness of several detection areas of the low-voltage distribution cabinet on the same plane.

[0026] In the above steps, the intelligent low-voltage distribution cabinet power distribution control system provided in this embodiment integrates high-precision sensors, which can continuously and in real time monitor the dust accumulation degree inside the low-voltage distribution cabinet. Once it is detected that the dust accumulation reaches the preset critical value, the system will automatically trigger the cleaning program, and use advanced dust collection or blowing technology to efficiently and thoroughly remove the dust in the cabinet, prevent dust from corroding the precision electronic components and electrical connection points inside the distribution cabinet, significantly extend the service life of the equipment, reduce the failure rate caused by dust, realize the intelligent control of the low-voltage distribution cabinet, and improve the overall operation efficiency and stability. At the same time, the built-in judgment module of the system adopts an advanced algorithm, which can accurately compare the current dust accumulation degree with the preset standard accumulation degree threshold. When it is detected that the dust accumulation exceeds the safe range, the module will automatically make a cleaning decision and start the cleaning program immediately; on the contrary, if the dust amount is below the safe level, the cleaning will not be performed, thereby avoiding excessive or unnecessary cleaning operations, saving precious energy resources, reducing manual intervention in the maintenance process, and greatly improving the operation and maintenance efficiency. Furthermore, in order to further optimize the working environment of the low-voltage distribution cabinet, the dust reduction module also has an innovative function - dynamic adjustment of the heat dissipation angle. By analyzing the changing trend of the dust growth over a period of time, the module can intelligently predict the possible situation of dust accumulation in the future, and automatically adjust the heat dissipation angle of the distribution cabinet to the optimal state accordingly. This dynamic adjustment strategy not only ensures that the distribution cabinet dissipates heat efficiently, but also effectively prevents the problem of poor heat dissipation caused by excessive dust accumulation, ensuring that the distribution cabinet can operate stably in the best state under various working conditions, and improving the reliability and safety of the system. Furthermore, the present invention has better analyzability for the division of the detection area. The basis for the division is the closed area on the surface of the internal wiring of the low-voltage distribution cabinet in the same horizontal plane interval. The detection area divided in this way can effectively characterize the difference in dust accumulation of the internal wiring between different planes, so as to facilitate further analysis.

[0027] Specifically, the detection module uses a light scattering method to obtain the dust accumulation degree of the low-voltage distribution cabinet by means of a plurality of light source transmitters and a plurality of reflected light receivers arranged in the low-voltage distribution cabinet.

[0028] Furthermore, a plurality of detection areas are arranged on the internal wiring surface of the low-voltage distribution cabinet.

[0029] In one embodiment, the above-mentioned detection area is based on the "GB / 50303-2015" "Code for Acceptance of Construction Quality of Building Electrical Engineering", and the detection area should be set at key locations such as busbar lap terminals, connectors, and densely packed wiring areas.

[0030] Specifically, when the light waves emitted by the light source transmitter encounter dust particles on the surface of the internal wiring, an interaction will occur, causing the light waves to deviate from the original propagation direction and emit light with the same frequency as the incident light in all directions, but the intensity will be weaker than the emitted light, thereby causing light scattering. When the reflected light receiver receives the light scattered by the dust on the surface of the internal wiring, the dust thickness can be reversely measured, thereby achieving accurate acquisition of the dust accumulation degree on the surface of the internal wiring of the low-voltage distribution cabinet.

[0031] In implementation, the light source transmitter can be realized by a laser transmitter in the prior art, and the reflected light receiver can be realized by a photoelectric sensor in the prior art, which will not be elaborated herein.

[0032] In detail, the dust accumulation degree can be obtained not only through the above-mentioned light scattering analysis, but also from the filter membrane sampling method or cluster analysis algorithm and hierarchical analysis method in the existing known technologies. It should be noted that according to the "GB / 12476.1-2013" standard, it is mentioned that "a dust layer thicker than 50mm will affect the normal operation of the distribution cabinet". Therefore, when obtaining the dust accumulation degree, the acquisition accuracy should be adjusted to 1mm to ensure that the precise value of the dust accumulation thickness can be accurately captured.

[0033] See also Figure 2 As shown, the detection module collects dust accumulation in each detection area including: Step S11, arranging a plurality of detection areas in the internal wiring area of ​​the same plane, and configuring a light source transmitter and a reflected light receiver for any detection area; Step S12, obtaining dust accumulation in the detection area by light scattering method; Step S13, calculating an average value based on the dust accumulation in different detection areas on the same plane as the dust accumulation concentration of the internal wiring area of ​​the low-voltage distribution cabinet.

[0034] In detail, the category of dust particle diameter needs to be determined in combination with the actual application scenario of the low-voltage distribution cabinet. For example, the diameter category is set to be greater than PM10.

[0035] Dust accumulation in low voltage distribution cabinets Determined by the following formula: , in, is the dust accumulation degree of the low voltage distribution cabinet, For the The area of ​​the detection area, Indicates Monitor the dust accumulation in the area. is the number of detection areas in the plane area.

[0036] As a preferred technical solution for the power distribution control system of the intelligent low-voltage power distribution cabinet, the determination module compares the dust accumulation degree obtained by the detection module with the standard accumulation degree; If the dust accumulation degree is greater than the standard accumulation degree, the determination module sends a cleaning instruction to the cleaning module; If the dust accumulation degree is less than the standard accumulation degree, the judgment module remains silent; Among them, the standard accumulation degree is related to the output voltage of the low-voltage distribution cabinet.

[0037] In detail, the output voltage of the low-voltage distribution cabinet used in daily work is between 220V and 660V. Dust accumulates on the surface of the device in the low-voltage distribution cabinet, which can easily reduce the insulation strength and cause discharge, especially in the presence of moisture or micro-condensation; it is also easy to damage the circuit board, causing the control system to malfunction or fail: dust will corrode the printed wires in the circuit board, the metal pins of the electronic components, etc., and even break them, making the control invalid or ineffective. The greater the output voltage of the low-voltage distribution cabinet, the greater the impact on the equipment caused by dust interference; therefore, the standard accumulation degree is set to 40mm~50mm according to the size of the output voltage of the low-voltage distribution cabinet. For example, the output voltage of the low-voltage distribution cabinet is 480V, and the corresponding standard accumulation degree is set to 45mm.

[0038] As a preferred technical solution for the power distribution control system of the intelligent low-voltage power distribution cabinet, the cleaning module includes a plurality of brushes arranged in parallel in opposite directions; When the cleaning module responds to the cleaning instruction, the brush cleans the plane of the detection area where the dust accumulation degree is greater than the standard accumulation degree until the dust accumulation degree is less than the standard accumulation degree.

[0039] In one embodiment, the output voltage of the low-voltage distribution cabinet is 480V, and the corresponding standard accumulation degree is set to 45mm. When the dust accumulation degree of the low-voltage distribution cabinet is greater than 45mm, the trigger judgment module sends a cleaning instruction to the above-mentioned cleaning module. When the cleaning module responds to the above-mentioned cleaning instruction, the brush is positioned to the area where the dust accumulation degree on the internal wiring surface of the low-voltage distribution cabinet is greater than 45mm, and the brush is driven to clean. Dust is removed from the internal wiring surface of the low-voltage distribution cabinet by cleaning. It is worth noting that the cleaning action of the brush includes rotation, reciprocating or other suitable designs until the dust accumulation degree is less than 45mm to ensure effective dust removal.

[0040] It is understandable that the above-mentioned brush positioning and cleaning can be achieved by any technical form in the prior art, which will not be elaborated here.

[0041] The low-voltage power distribution cabinet comprises a plurality of heat dissipation holes, and a single heat dissipation hole is composed of a plurality of louver-type heat dissipation baffles.

[0042] As the preferred technical solution for the distribution control system of the intelligent low-voltage distribution cabinet, the detection module performs secondary detection on the detection area after cleaning. Specifically, the detection module obtains the dust growth in several detection areas in any plane after cleaning in different time periods and after the same collection cycle.

[0043] The dust reduction module includes an analysis component and a torsion component; The analysis component is used to analyze the change trend of the dust growth amount, specifically, to compare the dust growth amount in different time periods with their corresponding standard growth amounts; If the dust growth amount is greater than the standard growth amount, the analysis component sends a dust reduction signal; If the dust growth amount is less than the standard growth amount, the analysis component remains silent.

[0044] It can be understood that the above-mentioned different time periods can be arbitrarily set according to the geographical environment and natural climate dust changes of the low-voltage distribution cabinet. For example, the above-mentioned different time periods can be set to 0:00-12:00; the two time periods of 12:00-24.00 correspond to the geographical environment and natural climate of the low-voltage distribution cabinet, such as windless weather and dusty weather. The dust growth in the same collection period from 0:00 to 12:00 in windless weather is smaller than the dust growth in dusty weather from 12:00 to 24:00. Therefore, dust is more likely to accumulate inside the low-voltage distribution cabinet during the period of 12:00-24:00, and the dust growth in different time periods is compared with the standard growth, so as to twist the heat dissipation angle of the heat dissipation baffle of the low-voltage distribution cabinet. For example, the torsion component twists the heat dissipation baffle in the period of 12:00-24:00; the above-mentioned same collection period can be arbitrarily set according to the operation time of the low-voltage distribution cabinet; the exemplary collection period can be set to 2h.

[0045] See also Figure 3 As shown, whether to reduce the heat dissipation angle is determined by the following steps: Step S11, obtaining the dust growth amount of several detection areas in any plane after cleaning in different time periods and the same collection cycle; Step S12, respectively comparing the dust growth amounts in different time periods with their corresponding standard growth amounts; Step S13, determining whether to enable the twisting component to twist a plurality of heat dissipation baffles in the heat dissipation holes with the smallest horizontal distance from any plane to reduce the heat dissipation angle.

[0046] When the dust growth on any plane of the low-voltage power distribution cabinet at different time periods is greater than the standard growth, the torsion component twists several heat dissipation baffles in the heat dissipation holes with the smallest horizontal distance from any plane to reduce the heat dissipation angle.

[0047] In detail, the standard increase amount is set according to the actual corrosion resistance and anti-interference conditions of the electronic components used in the low-voltage distribution cabinet. Exemplarily, the standard increase amount is set to 0.001 mm / h to 0.003 mm / h.

[0048] In implementation, the above-mentioned torsion component selects the heat dissipation hole with the smallest horizontal distance in any plane for twisting because it can effectively reduce the amount and rate of dust entering the low-voltage distribution cabinet, so as to minimize the degree of dust accumulation in the low-voltage distribution cabinet. Reducing dust accumulation can reduce electrical failures caused by dust, thereby effectively improving the performance and safety of the distribution cabinet.

[0049] See also Figure 4 and Figure 5 The torsion component responds to the dust reduction signal sent by the analysis component, and specifically, the torsion component twists several heat dissipation baffles in the same heat dissipation hole in the same direction and angle.

[0050] In implementation, the torsion component responds to the dust reduction signal sent by the analysis component, and twists the louver-type heat dissipation baffle 2 from the heat dissipation angle α1 to the heat dissipation angle β3, where the heat dissipation angle β is less than the heat dissipation angle α.

[0051] While ensuring the daily heat dissipation of the low-voltage distribution cabinet, by adjusting the angle of the heat dissipation baffle, the external dust can be reduced from directly entering the distribution cabinet, reducing the speed and amount of dust accumulation. Reducing dust accumulation can reduce electrical failures caused by dust, thereby effectively improving the performance and safety of the distribution cabinet.

The modules described may also be set in a processor, for example, it may be described as: a data processor includes a detection module, a determination module, a cleaning module, a storage module and a dust reduction module.
