Description

Technical Field

[0001] The present application relates to the field of outdoor electrical equipment, and in particular to a heat dissipation control method and system for an outdoor switch cabinet. Background Art

[0002] Outdoor switchgear is a kind of electrical equipment used in outdoor environment. Its main function is to open and close, control and protect electrical equipment in the process of power generation, transmission, distribution and energy conversion in the power system. The components in the switchgear mainly include circuit breakers, disconnectors, load switches, operating mechanisms, transformers and various protective devices.

[0003] In the related art, when the switch cabinet is in use, since the switch cabinet body is relatively closed and there are a large number of heat-generating components inside, if the heat is not dissipated in time, it may cause damage to the internal components, so the switch cabinet needs to be heat-dissipated. Among them, the heat dissipation treatment method corresponding to the switch cabinet is generally achieved by installing a heat dissipation device, which is electrically connected to a temperature sensor installed inside the switch cabinet. When the temperature detected by the temperature sensor is greater than the set temperature, the heat dissipation device is controlled to start to achieve heat dissipation treatment inside the switch cabinet.

[0004] In the above-mentioned related technologies, the heat dissipation device is generally fixedly installed at a certain position of the switch cabinet. At this time, the heat emitted by the components at any position inside still needs to travel a certain distance to reach the heat dissipation device. Once the heat emitted by the components far away from the switch cabinet is high, the heat movement process will still affect the overall temperature inside the switch cabinet, resulting in the heat dissipation effect of the heat dissipation device on the overall heat dissipation of the switch cabinet being poor. There is still room for improvement. Summary of the invention

[0023] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-Figure 8 It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0024] The embodiments of the present application are further described in detail below in conjunction with the drawings in the specification.

[0025] An embodiment of the present application discloses a heat dissipation control method for an outdoor switch cabinet. During the use of the switch cabinet, the temperature of the location of each component is monitored according to the temperature sensor inside the switch cabinet, and the position of the heat dissipation device is determined by simulation, so as to simulate the position where the heat dissipation device has the best working effect. At this time, the heat dissipation device is controlled to operate at this position, and the heat dissipation direction is adjusted according to the external wind direction, so that the heat dissipation device has a better overall heat dissipation effect on the inside of the switch cabinet.

[0026] Reference Figure 1 The method flow of the outdoor switch cabinet heat dissipation control method includes the following steps: Step S100: obtaining the internal collection temperature of each preset temperature collection point.

[0027] The temperature collection point is the location of the temperature sensor installed inside the switch cabinet. This location is near the component and is specifically set by the staff according to actual conditions. The internal collection temperature is the temperature value detected by the temperature sensor at the temperature collection point.

[0028] Step S101: randomly generate a virtual point in a preset device movement area, and determine the temperature heat dissipation distance according to the virtual point and each temperature collection point.

[0029] The device moving area is an area where the heat dissipation device can be moved and adjusted, the virtual point is a position point in the device moving area, and the temperature heat dissipation distance is the distance value between the virtual point and the temperature collection point.

[0030] Step S102: Calculate the single-point influencing parameters based on the internal collection temperature and the temperature heat dissipation distance of each temperature collection point, and calculate the overall influencing parameters based on all the single-point influencing parameters.

[0031] The single-point influence parameter reflects the influence of the heat emitted by the component on the overall temperature inside the switch cabinet. The larger the single-point influence parameter, the greater the influence of the emitted heat on the temperature inside the switch cabinet, that is, the heat dissipation effect at the temperature collection point is poor, and vice versa. The calculation formula of the single-point influence parameter is: ,in is a single point influencing parameter, is the temperature heat dissipation distance, is the internal temperature, as well as It is a preset fixed parameter for calculation; the overall influencing parameter is the sum of all single-point influencing parameters, that is, it reflects the influence of the heat emitted by all components on the internal temperature of the switch cabinet.

[0032] Step S103: determining the overall influencing parameter with the smallest value according to a preset sorting rule, defining the virtual point corresponding to the overall influencing parameter as a heat dissipation point, and controlling the preset heat dissipation device to move to the heat dissipation point in the device moving area to perform heat dissipation operation.

[0033] The sorting rule is a method set by the staff to sort the size of values, such as the bubbling method. The sorting rule can be used to determine the overall influencing parameter with the smallest value, that is, when the heat dissipation device operates at the virtual point corresponding to the overall influencing parameter, the heat dissipation effect that can be achieved is the best. At this time, the virtual point is defined as a heat dissipation point for identification, so as to control the heat dissipation device to move to the heat dissipation point for operation; the heat dissipation device can be an exhaust fan, and its movement is achieved by a mobile module arranged inside the switch cabinet.

[0034] Reference Figure 2 After the single-point influencing parameters are determined, the outdoor switch cabinet heat dissipation control method also includes: Step S200: establishing a detection interval on a preset time axis with the current time point as the end point and a width of a preset detection duration.

[0035] The time axis is a coordinate axis formed by the combination of various time points. The coordinate axis points from the time points that have been reached to the time points that have not yet been reached. The detection time is the time set by the staff to obtain data from the temperature collection point in a short period of time. The detection interval is established to facilitate the acquisition and analysis of data.

[0036] Step S201: performing a difference calculation based on the internal collected temperatures obtained at the front end point and the rear end point of the detection interval to determine the internal change temperature.

[0037] The internal change temperature is the temperature value of the internal collection temperature at the rear end point of the detection interval minus the internal collection temperature at the front end point of the detection interval.

[0038] Step S202: Calculate the temperature change rate according to the internal change temperature and the detection time.

[0039] The temperature change rate is the temperature change value of the component at the temperature collection point, which is determined by dividing the internal change temperature by the detection time.

[0040] Step S203: performing calculation according to the temperature change rate and the single-point influence parameter to update the single-point influence parameter.

[0041] The single-point influence parameter can be updated by multiplying the temperature change rate by the single-point influence parameter, so that the heat dissipation device can give priority to components with faster temperature rise when performing heat dissipation processing, thereby improving the overall heat dissipation effect.

[0042] Reference Figure 3 After the temperature change rate is determined, the outdoor switch cabinet heat dissipation control method also includes: Step S300: defining the temperature collection point for determining the temperature change rate as the primary point, and defining the remaining temperature collection points as the secondary points.

[0043] Define the main points and secondary points to distinguish the temperature collection points that need to be analyzed, which is convenient for subsequent analysis.

[0044] Step S301: determining the collection interval according to the main points and the secondary points, and determining the calculation weight parameter corresponding to the collection interval according to the preset weight matching relationship.

[0045] The collection interval distance is the straight-line distance between the main point and the secondary point, and the calculation weight parameter is the parameter used to calculate the collection interval distance. When the collection interval distance is large, it means that the distance between the two temperature collection points is far, that is, the temperature of the secondary point has little effect on the temperature of the main point. At this time, the corresponding calculation weight parameter is also small, and vice versa. The larger the weight, the greater the relationship between the two. The weight matching relationship between the two is determined by the staff in advance according to the arrangement of the temperature collection points, and it is necessary to ensure that all calculation weight parameters add up to one.

[0046] Step S302: Calculate the internal temperature of the cabinet according to the calculated weight parameter and the corresponding internal collected temperature.

[0047] The cabinet internal temperature is the cabinet internal temperature compared to the main point, and does not reflect the overall temperature inside the cabinet. The cabinet internal temperature is determined by multiplying all internal collected temperatures by corresponding calculation weight parameters.

[0048] Step S303: Determine the upper limit change rate corresponding to the internal temperature of the cabinet and the main points according to the preset temperature matching relationship.

[0049] The upper limit change rate is the maximum temperature change rate allowed when the components near the main points are working normally under the current internal temperature of the cabinet. That is, when the temperature change rate is greater than the upper limit change rate, it means that there are components near the main points working abnormally. The temperature matching relationship between the three is determined by the staff through experiments in advance.

[0050] Step S304: determine whether the temperature change rate is greater than the upper limit change rate.

[0051] The purpose of the judgment is to find out whether any component is working abnormally.

[0052] Step S3041: If the temperature change rate is not greater than the upper limit change rate, a component stability signal is output.

[0053] When the temperature change rate is not greater than the upper limit change rate, it indicates that there is basically no abnormal operation of the component. At this time, a component stability signal is output to allow the management personnel to be aware of the situation.

[0054] Step S3042: If the temperature change rate is greater than the upper limit change rate, a component abnormality signal is output.

[0055] When the temperature change rate is greater than the upper limit change rate, it indicates that a component may be operating abnormally and generating abnormal heat. At this time, a component abnormality signal is output to confirm the situation so that management personnel can intervene and handle it in time.

[0056] Reference Figure 4 After the overall influencing parameters are determined, the outdoor switch cabinet heat dissipation control method also includes: Step S400: Determine whether there are at least two virtual points with the same and minimum overall influencing parameters.

[0057] The purpose of judgment is to find out whether there are multiple virtual points that meet the requirements.

[0058] Step S4001: If there are not at least two virtual points with the same and minimum overall influence parameters, a heat dissipation point is determined according to the virtual point corresponding to the minimum overall influence parameter.

[0059] When there are not at least two virtual points with the same and minimum overall influencing parameters, it means that there are not multiple virtual points that meet the requirements, and the heat dissipation point determination can be performed normally.

[0060] Step S4002: If there are at least two virtual points with the same and minimum overall influence parameters, the virtual point corresponding to the minimum overall influence parameter is defined as a candidate point.

[0061] When there are at least two virtual points with the same and minimum overall influencing parameters, it means that there are multiple virtual points that meet the requirements, and further analysis is needed. They are defined as candidate points to distinguish different virtual points and facilitate subsequent analysis.

[0062] Step S401: performing calculations at each temperature collection point according to the internal collection temperature, the temperature change rate, and the preset unit time to determine the subsequent collection temperature.

[0063] The unit time is the time set by the staff for the heat dissipation device to move. The subsequent collected temperature is the temperature that can be changed after the unit time according to the currently determined temperature change rate, which is determined by multiplying the temperature change rate by the unit time and adding the internal collected temperature.

[0064] Step S402: determining the subsequent influencing parameters of each candidate point at the subsequent acquisition temperature, determining the subsequent influencing parameter with the smallest value according to the sorting rule, and determining the candidate point corresponding to the subsequent influencing parameter as the heat dissipation point.

[0065] The subsequent influencing parameter is the overall influencing parameter determined at the alternative point according to each subsequent collected temperature. The specific determination method is consistent with the overall influencing parameter and will not be elaborated here. The subsequent influencing parameter with the smallest value can be determined through the sorting rule. At this time, the corresponding alternative point is determined as the heat dissipation point, so that the subsequent heat dissipation device can be used more effectively.

[0066] Reference Figure 5 After the subsequent influencing parameters are determined, the outdoor switch cabinet heat dissipation control method also includes: Step S500: Determine whether there are at least two candidate points with the same and smallest subsequent influencing parameters.

[0067] The purpose of the judgment is to find out whether there are multiple alternative points that meet the requirements.

[0068] Step S5001: If there are not at least two candidate points with the same and smallest subsequent-order influencing parameters, a heat dissipation point is determined according to the candidate point corresponding to the smallest subsequent-order influencing parameter.

[0069] When there are not at least two candidate points with the same and smallest subsequent influencing parameters, it means that there is only one candidate point that meets the requirements, and in this case, it can be determined as the heat dissipation point.

[0070] Step S5002: If there are at least two candidate points with the same and smallest subsequent-order influencing parameters, the candidate point corresponding to the smallest subsequent-order influencing parameter is defined as a feasible point.

[0071] When there are at least two alternative points with the same and smallest subsequent impact parameters, it means that there are multiple alternative points that meet the requirements and further analysis is needed; feasible points are defined to identify the alternative points that meet the requirements, so as to distinguish different alternative points and facilitate subsequent analysis.

[0072] Step S501: Delineate a similar area at a feasible point with the feasible point as the midpoint and a preset unit distance as the radius.

[0073] The unit distance is a fixed distance set by the staff, and the similar area is delineated to define the point conditions around the feasible point to facilitate subsequent analysis.

[0074] Step S502: defining the subsequent influence parameter of each virtual point in the adjacent region as an adjacent influence parameter, and performing calculation according to all the adjacent influence parameters to determine the regional influence parameter.

[0075] Define similar influencing parameters to distinguish different subsequent influencing parameters. The regional influencing parameter can be obtained by calculating the mean of all similar influencing parameters. The regional influencing parameter reflects the heat dissipation effect of the heat dissipation device in the similar area when it is operating. The larger the value, the worse the effect of the heat dissipation device in the area.

[0076] Step S503: determining the regional influence parameter with the smallest value according to the sorting rule, and determining the feasible point corresponding to the regional influence parameter as the heat dissipation point.

[0077] The regional influence parameter with the smallest value can be determined through the sorting rules, that is, the heat dissipation effect is best when the heat dissipation device is currently operating in the nearby area. Therefore, the feasible point corresponding to the regional influence parameter is determined as the heat dissipation point, so that the subsequent heat dissipation device can perform better.

[0078] Reference Figure 6 When the heat dissipation device moves to the heat dissipation point to perform heat dissipation operation, the heat dissipation control method of the outdoor switch cabinet also includes: Step S600: Obtain the external wind direction of the device.

[0079] The external wind direction of the equipment is the external wind blowing direction of the environment where the outdoor switch cabinet is located, which can be obtained by using a wind vane outside the outdoor switch cabinet.

[0080] Step S601: determining a feasible heat dissipation direction interval corresponding to a heat dissipation point according to a preset direction matching relationship.

[0081] The feasible heat dissipation direction range is the air outlet direction range allowed when the heat dissipation device is at the heat dissipation point. Different heat dissipation points have different corresponding structures, and the corresponding feasible heat dissipation direction ranges are also different. The direction matching relationship between the two is determined and stored by the staff in advance through experiments.

[0082] Step S601: randomly generate a device heat dissipation direction in a feasible heat dissipation direction interval, and determine the direction angle according to the external wind direction of the equipment and the device heat dissipation direction.

[0083] The heat dissipation direction of the device is a direction in the feasible heat dissipation direction range, and the direction angle is the angle between the external wind direction of the equipment and the heat dissipation direction of the device.

[0084] Step S603: determining the direction angle with the smallest value according to the sorting rule, defining the device heat dissipation direction corresponding to the direction angle as the used heat dissipation direction, and controlling the heat dissipation device to adjust the heat dissipation port to the used heat dissipation direction.

[0085] The sorting rules can be used to determine the direction angle with the smallest value, that is, the heat dissipation direction is closest to the external wind direction at this time. At this time, the external wind force can be used to dissipate heat quickly, thereby reducing the difficulty of heat dissipation and improving the overall heat dissipation effect.

[0086] Reference Figure 7 When the heat dissipation device is performing heat dissipation operation at the heat dissipation point, the heat dissipation control method of the outdoor switch cabinet also includes: Step S700: define the current heat dissipation point as an original point, and define the overall influence parameter determined by the current original point as an original influence parameter.

[0087] The original point is defined to identify the location point where the heat dissipation device is currently operating, and the original influencing parameters are defined to distinguish different overall influencing parameters for the convenience of subsequent analysis.

[0088] Step S701: when the newly determined heat dissipation point does not coincide with the original point, performing difference calculation based on the newly determined overall influence parameter and the original influence parameter to determine the difference influence parameter.

[0089] The newly determined heat dissipation point is the new heat dissipation point determined when the heat dissipation point is re-determined after the heat dissipation device has operated for a preset fixed time. When the newly determined heat dissipation point does not coincide with the original point, it means that the heat dissipation device needs to be moved, and further analysis is required at this time; the difference influencing parameter is the difference in the overall influencing parameters obtained at the two position points at the time point when the new heat dissipation point is obtained, and the difference is determined by subtracting the overall influencing parameters determined by the new heat dissipation point from the original influencing parameters.

[0090] Step S702: Determine whether the difference impact parameter is greater than a preset reference demand parameter.

[0091] The benchmark requirement parameter is the minimum difference impact parameter set by the staff to determine whether the heat dissipation effects of the two position points differ greatly. The purpose of the judgment is to find out whether the heat dissipation effects of the two current position points differ greatly, that is, to judge whether it is necessary to control the movement of the heat dissipation device.

[0092] Step S7021: If the difference impact parameter is not greater than the reference demand parameter, the heat dissipation device is controlled to maintain the original state.

[0093] When the difference impact parameter is not greater than the reference demand parameter, it means that the heat dissipation effects of the two positions are not much different, and there is no need to move the heat dissipation device. At this time, the heat dissipation device can be controlled to maintain the original position.

[0094] Step S7022: If the difference impact parameter is greater than the reference demand parameter, the newly determined heat dissipation point is updated as a new original point, and the heat dissipation device is controlled to move to the original point to perform heat dissipation operation.

[0095] When the difference influencing parameter is greater than the reference demand parameter, it indicates that the heat dissipation effects obtained at the two position points have a large deviation. At this time, the original point is updated and the heat dissipation device is controlled to move so that the heat dissipation device can achieve a better heat dissipation effect on the switch cabinet.
