TECHNICAL FIELD

[0001] The present application relates to the technical field of environmental monitoring, and in particular to a purification method, system and device for a switch cabinet, a storage medium and computer equipment. BACKGROUND

[0002] The switch cabinet is a core electrical equipment widely used in the power generation, power transmission and power distribution links of the power system, which has the functions of power distribution, control and fault isolation protection, etc. Its main function is to open and close, control and protect the electrical equipment in the process of power generation, power transmission, power distribution and power conversion in the power system. In the power system, monitoring and management of the internal environment of the switch cabinet is the key to ensure the stability of the power system.

[0003] Most regions in China are located in monsoon climate areas, and are affected by the airflow of the ocean, so there are more rainy days and humid air. However, if the switch cabinet is in a humid operating environment for a long time, condensation may occur, which may cause equipment rust, abnormal discharge and equipment tripping accidents in the switch cabinet. At the same time, air pollution is serious in some cities, and there is a lot of dust in the air. The switch cabinet is prone to static electricity and dust absorption during operation, which reduces the heat dissipation capacity of the equipment. Further, static dust often contains acid, alkali and other components, which can erode the switch cabinet equipment and cause rust. Therefore, research on the prevention and control of switch cabinet condensation and static dust is helpful to reduce switch cabinet failures and improve the operation level of the power system.

[0004] Currently, the traditional switch cabinet environment purification work mainly monitors the characteristics of equipment rust and reduced conductivity caused by high-voltage switch cabinet condensation, and uses condensation dehumidification technology based on the characteristics to control condensation and dehumidification. However, the current switch cabinet environment purification method cannot monitor the environmental factors that may cause abnormal conditions before the switch cabinet environment deteriorates, resulting in poor purification effect of the switch cabinet environment.

[0028] The application will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0029] Currently, the traditional switch cabinet environment purification work mainly monitors the characteristics of equipment rust and conductive performance decline caused by high-voltage switch cabinet condensation, and uses condensation dehumidification technology based on the characteristics to control moisture and condensation. However, the current switch cabinet environment purification method does not monitor the environmental factors that may cause abnormal state before the switch cabinet environment deteriorates, resulting in poor effect of switch cabinet environment purification.

[0030] To solve the above problems, in one embodiment, as shown in Figure 1 A method for purifying a switch cabinet is provided. The method is applied to a switch cabinet, for example. It should be noted that the embodiments of the method are described in the application of the switch cabinet, and the environmental purification work of other cabinets can also be applied to the present embodiment. The method comprises the following steps:

[0031] 101. Obtain the environmental information of all grid spaces in the switch cabinet.

[0032] The switch cabinet can be an air-insulated high-voltage switch cabinet or other types of switch cabinets. The air-insulated high-voltage switch cabinet can be divided into a high-voltage part and a low-voltage part. The high-voltage part includes a cable chamber, a circuit breaker chamber, a bus chamber, and a front lower compartment. The low-voltage part is a relay protection chamber. The structure of the switch cabinet can be pre-processed by spatial grid division to obtain grid spaces with the same spatial complexity. The switch cabinet is composed of multiple grid spaces. Further, the environmental information can include temperature information, humidity information, particulate matter concentration information, and time range of particulate matter settlement phenomenon.

[0033] Specifically, an environmental sensor such as a temperature sensor, a humidity sensor, and a particulate matter concentration sensor can be arranged in each grid space of the switch cabinet. At the same time, a unified environmental sensor can also be arranged in the switch cabinet, and the probe of the environmental sensor is located in each grid space to obtain the environmental information of each grid space.

[0034] 102. Determine the condensation temperature threshold and the particulate matter deposition threshold of each grid space based on the environmental information of each grid space, and monitor the temperature information and the particulate matter concentration information of each grid space.

[0035] The condensation temperature threshold of each grid space can be the highest temperature at which condensation occurs in the grid space, calculated based on the environmental information of the grid space. When the air temperature in the switch cabinet is lower than the condensation temperature threshold, condensation will occur in the high-voltage switch cabinet. The particulate matter deposition threshold of each grid space can be the lowest particulate matter concentration at which particulate matter deposition occurs in the grid space, calculated based on the environmental information of the grid space. Further, the temperature information can be the current temperature information of each grid space, and the particulate matter concentration information can be the current particulate matter concentration information of each grid space.

[0036] Specifically, the condensation temperature threshold and the particulate matter deposition threshold of each grid space can be calculated based on the temperature information, humidity information, particulate matter concentration information, and time range of particulate matter deposition occurrence. Further, the temperature and particulate matter concentration information of each grid space can be obtained in real time based on the temperature sensor and particulate matter concentration sensor arranged in each grid space.

[0037] 103. Determine whether the temperature information of each grid space is less than or equal to the condensation temperature threshold of the grid space, and whether the particulate matter concentration information is greater than or equal to the particulate matter deposition threshold of the grid space.

[0038] Specifically, the temperature information and particulate matter concentration information of each grid space can be obtained in real time, and the temperature information and particulate matter concentration can be compared with the condensation temperature threshold and the particulate matter deposition threshold of the grid space, respectively, to determine whether the temperature information of each grid space is less than or equal to the condensation temperature threshold of the grid space, and whether the particulate matter concentration information of each grid space is greater than or equal to the particulate matter deposition threshold of the grid space.

[0039] 104. If the temperature information is less than or equal to the condensation temperature threshold and / or the particulate matter concentration information is greater than or equal to the particulate matter deposition threshold, perform environmental purification work on the switch cabinet.

[0040] The environmental purification work can be a circulating air control strategy for the switch cabinet, including temperature control, particulate matter purification, and environmental drying air dehumidification purification, etc., according to the arrangement of the circulating air system of the high-voltage switch cabinet.

[0041] Specifically, if one of the following conditions exists, i.e., the temperature information of a certain grid space is not greater than the condensation temperature threshold corresponding to the grid space, or the particulate matter concentration information of a certain grid space is not less than the particulate matter deposition threshold corresponding to the grid space, the environmental purification work is performed on the switch cabinet, so that the temperature of each grid space in the switch cabinet is greater than the condensation temperature threshold and the particulate matter concentration of each grid space is greater than the particulate matter deposition threshold, thereby avoiding the occurrence of condensation or particulate matter deposition in the switch cabinet.

[0042] The purification method of the switch cabinet provided by the embodiment first determines the temperature threshold at which condensation occurs and the particulate matter concentration threshold at which particulate matter deposition occurs for each grid space of the switch cabinet divided into multiple grid spaces. Then, the temperature information and the particulate matter concentration information of each grid space are monitored to determine whether the temperature information and the particulate matter concentration information of each grid space are within a range in which condensation and particulate matter deposition do not occur. If there is a grid space in which the temperature information or the particulate matter concentration information is within a range in which condensation and particulate matter deposition occur, the environmental purification is started to avoid the occurrence of condensation or particulate matter deposition in the switch cabinet. The application can establish grid spaces with equal spatial complexity among different rooms of the switch cabinet, such as the circuit breaker room, the relay protection room, and the cable room, and determine whether condensation occurs according to the real-time monitoring of temperature changes on the time axis and determine whether dust deposition occurs according to the real-time monitoring of the content of particulate matter PM2.5. Thus, when there is a possibility of condensation or particulate matter deposition in the switch cabinet, the environmental purification is performed on the switch cabinet to avoid the occurrence of damp condensation and electrostatic dust in the switch cabinet, thereby improving the environmental purification effect of the switch cabinet.

[0043] In one embodiment, the environmental information includes air temperature information and air humidity information, and the implementation method of determining the condensation temperature threshold corresponding to each grid space in step 102 can be as follows: first, based on the air temperature information and the air humidity information of the grid space, the air water saturation pressure of the grid space is calculated. The condensation temperature threshold generally refers to the temperature drop amplitude at which the water saturation of the humid air in the high-voltage switch cabinet forms liquid water under the same air pressure. Specifically, the air water saturation pressure r a at the water freezing point, the temperature correction coefficient h R in the high-voltage switch cabinet, and the absolute zero degree e can be used to calculate the air water saturation pressure r based on formula (1).

[0044]

[0045] wherein r b is the air water saturation pressure at the water freezing point, f is the temperature information of the current grid space, h R is the humidity information of the grid space, d is the temperature correction coefficient in the high-voltage switch cabinet, and e is the absolute zero degree, i.e., -273.15℃.

[0046] Then, based on the air water saturation pressure, the condensation temperature threshold of the grid space is calculated. Specifically, the condensation temperature threshold of each grid space can be calculated based on the air water saturation pressure r a The air water saturation pressure r b , the absolute zero degree e, and the temperature correction coefficient d in the high-voltage switch cabinet, based on formula (2) a ;

[0047]

[0048] The embodiments provided in the present application can accurately calculate the condensation temperature threshold of each grid space in the switch cabinet based on the specific conditions of each grid space, and further establish a condensation time evolution grid for spatial and temporal correlation analysis of condensation for each grid space, thereby providing a monitoring basis for subsequent environmental monitoring.

[0049] In one embodiment, the environmental information further includes quantity information of dates with zero deposition in a preset date range, and particulate matter concentration information in the grid space on each date with zero deposition. The preset date range can be the observation days of the switch cabinet particulate matter deposition before the current date, which can be a few days or a longer time range. Specifically, the number of days can be determined based on actual conditions, and the particulate matter concentration information of each day in the preset date range can be determined by the particulate matter sensor arranged in the switch cabinet. Further, the method for determining the particulate matter deposition threshold corresponding to each grid space in step 102 can be: based on the quantity information and each particulate matter concentration information, calculating the particulate matter deposition threshold corresponding to the grid space. The dust content in the air is usually calculated by the dust deposition amount, which refers to the natural deposition amount of particulate matter greater than 10 microns in the air. The dust deposition amount is directly related to the electrostatic dust. If the dust deposition amount is large, the electrostatic adsorption dust is more. The dust deposition amount is usually estimated by sampling with a vessel per month, but such method has a long collection period. Therefore, in order to facilitate calculation and air purification, the present embodiment estimates the dust deposition amount in the high-voltage switch cabinet by using the PM2.5 content determination method. PM2.5 refers to particulate matter greater than 2.5 microns in the air. When the PM2.5 value exceeds the particulate matter deposition threshold, prevention and control are performed. The particulate matter deposition threshold can be calculated according to formula (3) a :

[0050]

[0051] Wherein, n b is the number of dates with zero dust deposition, and j bi is the PM2.5 content of different dates with zero dust deposition.

[0052] The embodiment provided by the present application can calculate the particulate matter deposition threshold that causes particulate matter deposition based on the PM2.5 content of the grid space in the switch cabinet within a certain time span, and then establish an electrostatic dust time evolution grid for each grid space about the spatial and temporal correlation analysis of particulate matter deposition, thereby providing a judgment basis for environmental purification work.

[0053] In one embodiment, the method for determining the grid space of the switch cabinet can be:

[0054] First, the switch cabinet is taken as a root node, and the switch cabinet is spatially divided to obtain a plurality of space-time grids. Specifically, the switch cabinet can be spatially divided based on an octree structure division method. The octree structure division method is a three-dimensional space-time grid method, which uses a loop recursion to divide the three-dimensional space of an object into grids, thereby forming a spatial direction graph with a root node. In the embodiments of the present application, the switch cabinet can be taken as a root node for spatial division to obtain eight space-time grids. Then, a loop process is executed until a preset condition is met, wherein the loop process includes:

[0055] The space-time grid division probability of each space-time grid is calculated, and it is determined whether each space-time grid division probability is equal. Specifically, the space-time grid division probability of each space-time grid can be calculated by formula (4) and formula (5);

[0056] First, the real space coefficient of each space-time grid is calculated:

[0057]

[0058] wherein g z is the real space coefficient of the space-time grid, s a is the probability of switch cabinet space-time grid division.

[0059] Then, the switch cabinet space-time grid division reversible transformation is performed to obtain the probability s a of high-voltage switch cabinet space-time grid division.

[0060]

[0061] Further, if each of the spatio-temporal grid division probabilities is not equal, each of the spatio-temporal grids is spatially segmented to obtain segmented spatio-temporal grids, and the step of calculating the spatio-temporal grid division probability of each of the spatio-temporal grids and determining whether each of the spatio-temporal grid division probabilities is equal is performed. Specifically, the spatio-temporal grid division probabilities of all spatio-temporal grids can be obtained, and it is determined whether each of the spatio-temporal grid division probabilities is equal. In the case where each of the spatio-temporal grid division probabilities is not equal, each of the spatio-temporal grids is segmented based on the octree structure division method to obtain new spatio-temporal grids. The preset condition is that each of the spatio-temporal grid division probabilities is equal. Finally, the spatio-temporal grid value of each of the spatio-temporal grids is calculated, and the spatio-temporal grid value is determined as the grid space. Specifically, in the case where each of the spatio-temporal grid division probabilities is equal, it can be determined that each of the spatio-temporal grids has the same spatial complexity, and then the spatio-temporal grid value b of each of the spatio-temporal grids can be calculated based on formula (6) a :

[0062]

[0063] wherein c t-1 is the grid division observation data value at the previous moment; and c t is the grid division observation data value at the current moment. Further, the spatio-temporal grid value can be used to determine the grid space.

[0064] In the embodiments of the present application, the spatio-temporal structure can be analyzed according to the type structure of different switch cabinets, and the grid space can be established according to the structure of the switch cabinet. Compared with the technical scheme of monitoring and purifying the switch cabinet as a whole, the grid space can be established between different rooms of the switch cabinet, such as the circuit breaker room, the relay protection room, and the cable room, so that different space regions of the switch cabinet can be distinguished in more detail, the spatio-temporal grid of the condensation point and the particulate matter can be established for each space region, the evolution form of the spatio-temporal grid of the switch cabinet can be established for each spatio-temporal grid, and the environment of the switch cabinet can be better monitored and purified.

[0065] In one embodiment, the implementation manner of step 104 of performing environmental purification work on the switch cabinet includes: first, obtaining the humid air density information in the grid space and the internal cavity volume information of the switch cabinet, and calculating the condensation time of each of the grid spaces based on the humid air density information and the internal cavity volume information. The internal cavity volume information of the switch cabinet can be the volume of the total space in the switch cabinet. Specifically, the humid air density information in each grid space can be measured by a humidity sensor arranged in the switch cabinet. Further, based on formula (7), the condensation time t of each of the grid spaces can be calculated together with the previously measured diffusion speed of the humid air in the switch cabinet and the humid air density information:

[0066]

[0067] wherein q is the diffusion speed of the humid air in the switch cabinet, λ is the density of the humid air in the switch cabinet, and ω is the volume of the inner cavity of the switch cabinet.

[0068] Further, the shortest dew condensation time among all the grid spaces is determined, and the environmental purification work is started at a time interval set based on the dew condensation time, wherein the time interval is not greater than the dew condensation time t.

[0069] Further, the shortest dew condensation time among all the grid spaces is determined, and the environmental purification work is started at a time interval set based on the dew condensation time. The time interval is not greater than the dew condensation time. Specifically, the dew condensation times t of each grid space are compared, and the minimum dew condensation time t among the dew condensation times t is obtained. min Further, a time interval smaller than the minimum dew condensation time t min is set, and the time interval is used as the evolution time of the dew condensation and the particle deposition in the switch cabinet. When the grid space of the switch cabinet reaches the threshold of the dew condensation and the particle deposition, the environmental purification is started within the minimum dew condensation time t min to avoid the phenomenon of the dew condensation and the particle deposition in the switch cabinet, and to improve the environmental purification effect of the switch cabinet. In the embodiments of the present application, the temperature and humidity sensor and the PM2.5 sensor are installed in each grid of the switch cabinet to collect the temperature and humidity and the PM2.5 concentration data, and the spatial and temporal correlation analysis is performed, that is, the dew point temperature of each high-voltage switch cabinet space-time grid is correlated with the dew condensation time, and the minimum dew condensation time is calculated according to the grid, so as to establish the evolution mode of the high-voltage switch cabinet space-time grid.

[0070] In one embodiment, after step 104, the method further includes: if the temperature information is greater than the condensation temperature threshold and the particulate matter concentration information is less than the particulate matter settling threshold, then the environmental purification work on the switchgear is stopped. Specifically, based on sensors installed inside the switchgear, the temperature and particulate matter concentration information of each grid inside the switchgear are monitored in real time. When the temperature and particulate matter concentration information of each grid meets the requirements regarding the condensation temperature threshold and the particulate matter settling concentration threshold, the environmental purification work on the switchgear is stopped. Further, after the environmental purification work on the switchgear is stopped, the purification work can be repeatedly turned on and off, using the condensation time obtained in the above steps as the time interval and the length of time from starting the purification work to stopping the purification work in the above steps as the purification duration, so that the switchgear is always in a good operating environment. In the embodiments of this application, the purification work can be turned off after the environment inside the switchgear is in a good operating environment, thereby reducing the energy consumption of the environmental purification system.

[0071] The switchgear purification method provided in this embodiment divides the switchgear into multiple grid spaces with the same spatial complexity, and establishes a spatiotemporal grid for condensation points and particulate matter settling in each grid space. For each spatiotemporal grid, the evolution morphology of the switchgear's spatiotemporal grid is established, enabling targeted analysis of the condensation and electrostatic adsorption dust characteristics of different structures within the switchgear, thus achieving precise control of the switchgear environment. This method significantly improves the accuracy of environmental control for switchgear and enhances the operation, maintenance, and management level of high-voltage switchgear.

[0072] Furthermore, such as Figure 2 As shown in the figure, this application embodiment also provides a purification system for a switch cabinet, applied in a switch cabinet 100, including multiple environmental sensors 130, an air purification host 120, and a system for performing the above-mentioned functions. Figure 1 The environmental control module 110 of the purification method for the switchgear shown.

[0073] Specifically, the data transmitting end of each environmental sensor 130 is connected to the data receiving end of the environmental control module 110, and each environmental sensor 130 is disposed at a preset installation position 140 within the switch cabinet 100. The installation position 140 can be set based on the grid space into which the switch cabinet 100 is divided, so that each grid space has one environmental sensor 130 for collecting environmental information required by the purification method of the switch cabinet, such as temperature, humidity, and particulate matter concentration.

[0074] The data transceiver end of the air purification host 120 is connected with the data transceiver end of the environment control module 110, and the air purification host 120 is provided with at least one wind power output pipeline 160, and each wind power output pipeline 160 is communicated to a preset installation area 150 in the switch cabinet 100 for the wind power output pipeline 160. Among them, the air purification host 120 can be an air conditioning device capable of performing moisture decomposition processing and temperature control of humid air, and the installation area 150 can be the inside of each equipment room in the switch cabinet, such as the cable room, the circuit breaker room, the busbar room, the front lower compartment and the relay protection room, etc., so that the air purification host 120 can perform environmental purification work on each equipment room based on the wind power output pipeline 160. The specific installation position of the installation area 150 can be determined based on the actual situation.

[0075] The purification system of the switch cabinet provided by the embodiment can obtain environmental information of the grid space based on the environmental sensor, and determine whether the temperature and particulate matter concentration information in the switch cabinet reach the threshold of condensation or particulate matter deposition based on the environment control module. When the conditions of condensation or particulate matter deposition may occur in the switch cabinet, the air purification host performs purification work on the environment of the installation area based on the wind power output pipeline of the air purification host, thereby improving the efficiency of the environmental purification work. In addition, it should be noted that the data processing function in the environment control module in the embodiment can be realized by a software program, and the functions realized by the purification system of the switch cabinet proposed in the embodiment are mainly realized through the connection relationship between the devices in the structure.

[0076] As Figure 1 As shown in the specific implementation of the method, the embodiment provides a purification device of a switch cabinet, as shown in the specific implementation of the method. Figure 3 The device comprises a space division module 31, an environment analysis module 32, an environment determination module 33 and a purification execution module 34.

[0077] The space division module 31 can be used to obtain environmental information of all grid spaces in the switch cabinet which are pre-divided, wherein each grid space has the same space complexity;

[0078] The environment analysis module 32 can be used to determine a condensation temperature threshold and a particulate matter deposition threshold corresponding to each grid space based on the environmental information of each grid space, and monitor temperature information and particulate matter concentration information of each grid space;

[0079] The environment determination module 33 can be used to determine whether the temperature information of each grid space is less than or equal to the condensation temperature threshold corresponding to the grid space, and whether the particulate matter concentration information is greater than or equal to the particulate matter deposition threshold corresponding to the grid space;

[0080] The purification execution module 34 can be used to perform environmental purification on the switch cabinet if the temperature information is less than or equal to the condensation temperature threshold and / or the particulate matter concentration information is greater than or equal to the particulate matter deposition threshold.

[0081] In a specific application scenario, the environmental information includes air temperature information and air humidity information; the environmental analysis module 32 can specifically be used to calculate the air water saturation pressure of the grid space based on the air temperature information and the air humidity information of the grid space; and calculate the condensation temperature threshold of the grid space based on the air water saturation pressure.

[0083] In a specific application scenario, the space division module 31 can specifically be used to divide the space of the switch cabinet as a root node to obtain a plurality of space-time grids; and perform a loop process until a preset condition is met, wherein the loop process includes: calculating the space-time grid division probability of each space-time grid, and determining whether each space-time grid division probability is equal; if each space-time grid division probability is not equal, performing space division on each space-time grid to obtain a divided space-time grid, and performing the steps of calculating the space-time grid division probability of each space-time grid and determining whether each space-time grid division probability is equal; and the preset condition is that each space-time grid division probability is equal; calculating the space-time grid value of each space-time grid, and determining the space-time grid value as the grid space.

[0084] In a specific application scenario, the purification execution module 34 can specifically be used to obtain the humid air density information in the grid space and the internal cavity volume information of the switch cabinet, and calculate the condensation time of each grid space based on the humid air density information and the internal cavity volume information; determine the shortest condensation time among all the condensation times of the grid spaces, and start the environmental purification work at a time interval set based on the condensation time, wherein the time interval is not greater than the condensation time.

[0085] In a specific application scenario, the purification execution module 34 can specifically be used to stop performing environmental purification on the switch cabinet if the temperature information is greater than the condensation temperature threshold and the particulate matter concentration information is less than the particulate matter deposition threshold.

[0086] It should be noted that other corresponding descriptions of the various functional units involved in the purification device of the switch cabinet provided in the embodiment can be referred to the corresponding descriptions in Figure 1 , which will not be repeated here.

[0087] Based on the method as shown in Figure 1 , correspondingly, the embodiment also provides a storage medium having a computer program stored thereon, which is executed by a processor to implement the purification method of the switch cabinet as shown in Figure 1 .
