Description

Technical Field

[0001] The present invention belongs to the technical field of remote monitoring of ring main units, and in particular relates to a remote real-time monitoring and diagnosis method and system for a ring main unit. Background Art

[0002] Ring main unit is an important power distribution equipment in the power system, which is used to ensure the continuity and reliability of power supply. The remote monitoring technology of ring main unit plays a vital role in the operation and maintenance management of the power system. With the rapid development of the power industry and the improvement of the automation level, the requirements for the real-time monitoring and fault diagnosis capabilities of ring main unit are also increasing. At present, the remote monitoring system of ring main unit mainly focuses on monitoring parameters such as voltage, current, temperature, etc. to realize fault warning and processing.

[0003] When the remote monitoring system of the ring main unit finds that multiple electrical components on a certain level of the installation panel in the ring main unit have abnormal heat at the same time, it will generally directly determine that it is caused by a series fault of the electrical components. However, in fact, the overall abnormal heat of the installation panel may also be caused by excessive dust coverage on its surface;

[0004] In current technology, once the overall thermal anomaly of the electrical components on the installation panel is detected, maintenance personnel are usually dispatched directly for inspection without first determining whether it is caused by dust accumulation. This practice may lead to the misjudgment of the overall thermal anomaly as a series fault, which will cause unnecessary professional maintenance personnel to be dispatched, significantly increasing the maintenance cost of the ring main unit.

[0055] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0056] Figure 1 A flow chart of a method provided by an embodiment of the present invention is shown.

[0057] Specifically, a method for remote real-time monitoring and diagnosis of a ring main unit comprises the following steps:

[0058] Step S100, real-time temperature monitoring of electrical components on installation panels at each level in the target ring network cabinet is performed, and when it is found that a preset proportion of electrical components on an installation panel at a certain level have abnormal temperatures, the installation panel at this level is determined to be an abnormal installation panel with overall thermal anomalies.

[0059] Specifically, Figure 2 A flow chart for determining abnormal installation panels that exhibit overall thermal anomalies is shown.

[0060] Among them, real-time temperature monitoring of electrical components on installation panels at each level in the target ring network cabinet is performed, and when it is found that a preset proportion of electrical components on an installation panel at a certain level have abnormal temperatures, determining that the installation panel at this level is an abnormal installation panel with overall thermal abnormality specifically includes the following steps:

[0061] Step S101, using infrared thermal sensing technology to obtain the real-time temperature of each electrical component on each level of the installation panel;

[0062] Step S102, monitoring the real-time temperature of each electrical component;

[0063] Step S103, when it is found that a preset proportion of electrical components on a certain level of installation panel have temperature abnormalities under the same heat dissipation conditions, the installation panel at this level is determined to be an abnormal installation panel with overall thermal abnormalities.

[0064] In the embodiment of the present invention, a plurality of installation panels are sequentially arranged inside the target ring network cabinet from high to low, and each installation panel has a unique number, and various types of electrical components are installed on the installation panels. The target ring network cabinet is also equipped with an infrared thermal imager, and the infrared thermal imager can monitor the temperature of electrical components installed on different levels. The target ring network cabinet is equipped with air cooling measures commonly used in the prior art, and the air cooling measures can effectively blow and dissipate heat for each independently arranged installation panel;

[0065] When the infrared thermal imager performs real-time temperature monitoring on the electrical components on the installation panels at different levels, if it is found that a certain number of electrical components on the installation panel at a certain level have exceeded the preset temperature threshold, and the ratio of the above certain number to the total number of all electrical components on the installation panel at this level exceeds the preset ratio, it means that the installation panel at this level has an overall thermal anomaly, that is, the installation panel at this level is an abnormal installation panel. The above preset ratio can be manually adjusted by the target ring network cabinet manager;

[0066] It is understandable that under the same heat dissipation conditions (the same air cooling measures), when there is no overall thermal anomaly in the installation panels of other levels except the abnormal installation panel, it indirectly indicates that there are two main reasons for the overall thermal anomaly of the abnormal installation panel. One is that the electrical components on the abnormal installation panel have a series fault, and the other is that the surface of the abnormal installation panel is covered with too much dust, resulting in the electrical components covered with more dust cannot be well cooled by the heat dissipation measures, which leads to the abnormal temperature of the panel itself. Therefore, when the background processing cloud determines that the target ring network cabinet is not in overload operation, when it is found that the installation panel of a certain level has an overall thermal anomaly, the cause of this phenomenon should be further determined. If it is determined that the cause of the overall thermal anomaly of the abnormal installation panel is excessive dust coverage, it is only necessary to dispatch special cleaning personnel nearby to clean the dust on the surface of the abnormal installation panel, and there is no need to remotely deploy professional ring network cabinet maintenance personnel to perform maintenance work on the target ring network cabinet.

[0067] like Fig. 9 As shown, the heat dissipation measures of the target ring main unit include:

[0068] A heat dissipation fan, and the heat dissipation fan is equipped with a main ventilation duct, and the main ventilation duct is equipped with a plurality of auxiliary ventilation ducts corresponding to the surfaces of the installation panels at different levels, and the auxiliary ventilation ducts are equipped with electric control valves;

[0069] The heat dissipation vents are opened on the surface of the target ring network cabinet, and a dust content measuring element is installed near the heat dissipation vents inside the target ring network cabinet. The dust content measuring element can be a resistive particle sensor or a light scattering dust sensor.

[0070] Furthermore, the ring main unit remote real-time monitoring and diagnosis method further comprises the following steps:

[0071] Step S200, after determining the abnormal installation panel with the overall thermal anomaly, a targeted purge operation is performed on the abnormal installation panel through the heat dissipation measures of the target ring main unit.

[0072] Specifically, Figure 3 A flow chart showing a targeted purge operation on an abnormally installed panel through heat dissipation measures of a target ring main unit is shown.

[0073] Among them, after determining the abnormal installation panel with overall thermal anomaly, the targeted purging operation of the abnormal installation panel is carried out through the heat dissipation measures of the target ring network cabinet, which specifically includes the following steps:

[0074] Step S201, after determining an abnormal installation panel with an overall thermal abnormality, determining an auxiliary ventilation duct corresponding to the abnormal installation panel;

[0075] Step S202, closing all the electronically controlled valves on the auxiliary ventilation ducts except the auxiliary ventilation duct corresponding to the abnormally installed panel;

[0076] Step S203, blowing air into the main ventilation duct and the auxiliary ventilation duct corresponding to the abnormally installed panel through the heat dissipation fan, so as to perform a targeted purge operation on the abnormally installed panel.

[0077] In the embodiment of the present invention, when the abnormal installation panel is subjected to targeted blowing operation through the heat dissipation fan, the main ventilation duct and the auxiliary ventilation duct corresponding to the abnormal installation panel, the wind force of the heat dissipation fan should be appropriately increased;

[0078] It is understandable that the dust that has covered the installation panel and electrical components cannot be fully blown away by the wind blown out from the auxiliary ventilation duct due to the adsorption force between the dust and the electrical components. However, a part of the dust attached to the installation panel can be blown away by a cooling fan with a high wind speed. It should be understood that the greater the dust coverage on the surface of the installation panel, the more dust can be blown away, that is, the greater the amount of dust entering the internal air of the target ring network cabinet.

[0079] Furthermore, the ring main unit remote real-time monitoring and diagnosis method further comprises the following steps:

[0080] Step S300, when performing a purge operation on an abnormally installed panel, evaluating the dust content of the flowing air in the target ring main unit;

[0081] Step S400, based on the dust content of the flowing air in the target ring main unit, determine whether the dust coverage of the abnormally installed panel exceeds the preset threshold. If it is determined that the dust coverage of the abnormally installed panel exceeds the preset threshold, generate panel surface cleaning information based on the number of the abnormally installed panel and send it to the ring main unit administrator terminal.

[0082] Specifically, Figure 4 A flow chart for evaluating the dust content of the air flowing within a target ring main unit is shown.

[0083] When performing the purge operation on the abnormally installed panel, evaluating the dust content of the flowing air in the target ring main unit specifically includes the following steps:

[0084] Step S301, while performing a purge operation on the abnormally installed panel, a dust content measuring element is operated;

[0085] Step S302: obtaining the dust content of the flowing air in the target ring main unit through a dust content measuring element.

[0086] Specifically, Figure 5 A flow chart is shown for determining whether the dust coverage of an abnormally installed panel exceeds a preset threshold.

[0087] Among them, according to the dust content of the flowing air in the target ring network cabinet, it is judged whether the dust coverage of the abnormal installation panel exceeds the preset threshold. If it is judged that the dust coverage of the abnormal installation panel exceeds the preset threshold, the panel surface cleaning information is generated according to the number of the abnormal installation panel and sent to the ring network cabinet manager terminal. Specifically, the following steps are included:

[0088] Step S401, calling a preset dust coverage comparison table, and searching the preset dust coverage corresponding to the dust content of the flowing air in the target ring network cabinet in the preset dust coverage comparison table;

[0089] Step S402, determining whether the found preset dust coverage amount is greater than a preset threshold;

[0090] Step S403: If it is determined that the found preset dust coverage is greater than the preset threshold, panel surface cleaning information is generated according to the number of the abnormally installed panel and sent to the ring main unit manager terminal.

[0091] In the embodiment of the present invention, the preset dust coverage comparison table is a table obtained by technicians in this field after multiple tests, and the main content of the table is: in the target ring network cabinet, under the blowing conditions of the same wind force, the dust content of the flowing air corresponding to different preset dust coverage on the installation panel (it should be noted that the preset dust coverage and the corresponding flowing air dust content are both range values), and the preset threshold value means that when the dust coverage on the surface of the installation panel is greater than a certain value, it means that the electrical components on the installation panel will not be able to perform normal heat dissipation due to the excessive dust coverage. Generally speaking, the preset threshold value is obtained by technicians in this field after multiple tests;

[0092] When the abnormal installation panel is purged with strong wind through the heat dissipation fan, the main ventilation duct and the auxiliary ventilation duct corresponding to the abnormal installation panel, the dust content measuring element arranged near the heat dissipation air outlet in the target ring network cabinet can directly measure the air containing the dust of the abnormal installation panel;

[0093] It can be understood that, since only the auxiliary ventilation duct corresponding to the abnormal installation panel can discharge air, the air in the target ring network cabinet at this time will only contain dust blown out from the abnormal installation panel, and then the dust content of the flowing air measured by the dust content measuring element corresponds to the dust coverage of the abnormal installation panel. After the dust content of the flowing air in the target ring network cabinet at this time is determined by the dust content measuring element in the background processing cloud, the background processing cloud retrieves the preset dust coverage comparison table, and searches the preset dust coverage corresponding to the dust content of the flowing air in the target ring network cabinet in the preset dust coverage comparison table, and determines whether the preset dust coverage found is greater than the preset threshold value. If it is determined that the preset dust coverage found is greater than the preset threshold value, the panel surface cleaning information is generated according to the number of the abnormal installation panel, and sent to the ring network cabinet manager terminal, so that the ring network cabinet manager can dispatch dust cleaning personnel as soon as possible to fully clean the abnormal installation panel;

[0094] It should be noted that although the background processing cloud determines that the overall thermal anomaly of the abnormal installation panel may be related to the excessive dust coverage on its surface, it may also be a situation where there is excessive dust coverage and a series fault. Therefore, after cleaning the dust on the abnormal installation panel, the background processing cloud continues to observe whether the abnormal installation panel still has an overall thermal anomaly. If not, it means that the cause of the thermal anomaly of the abnormal installation panel has been resolved. If it still exists, it means that the abnormal installation panel still has a series fault problem. At this time, the background processing cloud should promptly provide feedback to the target ring network cabinet manager.

[0095] Through the above technical solution, when remotely monitoring the operation of the ring network cabinet, if it is found that the installation panel in the ring network cabinet is overheated as a whole, it can be intelligently judged whether this thermal anomaly is mainly caused by excessive accumulation of dust on the surface. If it is confirmed that it is caused by dust accumulation, only cleaning personnel need to be dispatched to clean the ring network cabinet, and there is no need to use professional maintenance personnel. This technical means can avoid unnecessary dispatch of professionals due to misjudgment of the overall thermal anomaly of the installation panel as a series fault, thereby effectively reducing the maintenance cost of the ring network cabinet.

[0096] Furthermore, Figure 6 The application architecture diagram of the system provided by the embodiment of the present invention is shown.

[0097] Among them, in another preferred embodiment provided by the present invention, a remote real-time monitoring and diagnosis system for a ring main unit includes:

[0098] The abnormal installation panel determination module 100 is used to perform real-time temperature monitoring of electrical components on installation panels at each level in the target ring network cabinet, and when it is found that a preset proportion of electrical components on an installation panel at a certain level have abnormal temperatures, the installation panel at this level is determined to be an abnormal installation panel with overall thermal abnormality.

[0099] Specifically, Figure 7 It shows a structural block diagram of the abnormal installation panel determination module 100 in the system provided by an embodiment of the present invention.

[0100] Among them, in the preferred embodiment provided by the present invention, the abnormal installation panel determination module 100 specifically includes:

[0101] The real-time temperature acquisition unit 101 is used to acquire the real-time temperature of each electrical component on each level of the installation panel by using infrared thermal sensing technology;

[0102] A real-time temperature monitoring unit 102 is used to monitor the real-time temperature of each electrical component;

[0103] The abnormal installation panel determination unit 103 is used to determine that the installation panel at a certain level is an abnormal installation panel with overall thermal anomaly when it is found that a preset proportion of electrical components on the installation panel at a certain level have temperature anomalies under the same heat dissipation conditions.

[0104] Several installation panels are arranged in order from high to low inside the target ring network cabinet, and each installation panel has a unique number. Various electrical components are installed on the installation panels. The target ring network cabinet is also equipped with an infrared thermal imager, and the infrared thermal imager can monitor the temperature of electrical components installed on different levels. The target ring network cabinet is equipped with air cooling measures commonly used in the prior art, and the air cooling measures can effectively blow and dissipate heat for each independently set installation panel;

[0105] When the infrared thermal imager performs real-time temperature monitoring on the electrical components on the installation panels at different levels, if it is found that a certain number of electrical components on the installation panel at a certain level have exceeded the preset temperature threshold, and the ratio of the above certain number to the total number of all electrical components on the installation panel at this level exceeds the preset ratio, it means that the installation panel at this level has an overall thermal anomaly, that is, the installation panel at this level is an abnormal installation panel. The above preset ratio can be manually adjusted by the target ring network cabinet manager;

[0106] It is understandable that under the same heat dissipation conditions (the same air cooling measures), when there is no overall thermal anomaly in the installation panels of other levels except the abnormal installation panel, it indirectly indicates that there are two main reasons for the overall thermal anomaly of the abnormal installation panel. One is that the electrical components on the abnormal installation panel have a series fault, and the other is that the surface of the abnormal installation panel is covered with too much dust, resulting in the electrical components covered with more dust cannot be well cooled by the heat dissipation measures, which leads to the abnormal temperature of the panel itself. Therefore, when the background processing cloud determines that the target ring network cabinet is not in overload operation, when it is found that the installation panel of a certain level has an overall thermal anomaly, the cause of this phenomenon should be further determined. If it is determined that the cause of the overall thermal anomaly of the abnormal installation panel is excessive dust coverage, it is only necessary to dispatch special cleaning personnel nearby to clean the dust on the surface of the abnormal installation panel, and there is no need to remotely deploy professional ring network cabinet maintenance personnel to perform maintenance work on the target ring network cabinet.

[0107] like Fig. 9 As shown, the heat dissipation measures of the target ring main unit include:

[0108] A heat dissipation fan, and the heat dissipation fan is equipped with a main ventilation duct, and the main ventilation duct is equipped with a plurality of auxiliary ventilation ducts corresponding to the surfaces of the installation panels at different levels, and the auxiliary ventilation ducts are equipped with electric control valves;

[0109] The heat dissipation vents are opened on the surface of the target ring network cabinet, and a dust content measuring element is installed near the heat dissipation vents inside the target ring network cabinet. The dust content measuring element can be a resistive particle sensor or a light scattering dust sensor.

[0110] Furthermore, the ring main unit remote real-time monitoring and diagnosis system also includes:

[0111] The purge operation implementation module 200 is used to implement a targeted purge operation on the abnormal installation panel through the heat dissipation measures of the target ring main unit after determining the abnormal installation panel with overall thermal abnormality.

[0112] Specifically, Figure 8The structure block diagram of the purge operation implementation module 200 in the system provided by the embodiment of the present invention is shown.

[0113] Among them, in the preferred embodiment provided by the present invention, the purge operation implementation module 200 specifically includes:

[0114] The auxiliary ventilation duct determination unit 201 is used to determine the auxiliary ventilation duct corresponding to the abnormal installation panel after determining the abnormal installation panel with the overall thermal abnormality phenomenon;

[0115] The electric-controlled valve control unit 202 is used to close all the electric-controlled valves carried on the auxiliary ventilation pipes except the auxiliary ventilation pipe corresponding to the abnormal installation panel;

[0116] The purge operation implementation unit 203 is used to blow air into the main ventilation duct and the auxiliary ventilation duct corresponding to the abnormally installed panel through the heat dissipation fan, so as to implement a targeted purge operation on the abnormally installed panel.

[0117] In the embodiment of the present invention, when the abnormal installation panel is subjected to targeted blowing operation through the heat dissipation fan, the main ventilation duct and the auxiliary ventilation duct corresponding to the abnormal installation panel, the wind force of the heat dissipation fan should be appropriately increased;

[0118] It is understandable that the dust that has covered the installation panel and electrical components cannot be fully blown away by the wind blown out from the auxiliary ventilation duct due to the adsorption force between the dust and the electrical components. However, a part of the dust attached to the installation panel can be blown away by a cooling fan with a high wind speed. It should be understood that the greater the dust coverage on the surface of the installation panel, the more dust can be blown away, that is, the greater the amount of dust entering the internal air of the target ring network cabinet.

[0119] Furthermore, the ring main unit remote real-time monitoring and diagnosis system also includes:

[0120] A dust content assessment module 300 is used to assess the dust content of the flowing air in the target ring main unit when performing a purge operation on an abnormally installed panel;

[0121] The dust coverage judgment module 400 is used to judge whether the dust coverage of the abnormally installed panel exceeds a preset threshold value based on the dust content of the flowing air in the target ring network cabinet. If it is determined that the dust coverage of the abnormally installed panel exceeds the preset threshold value, the panel surface cleaning information is generated according to the number of the abnormally installed panel and sent to the ring network cabinet management personnel terminal.

[0122] In the embodiment of the present invention, the preset dust coverage comparison table is a table obtained by technicians in this field after multiple tests, and the main content of the table is: in the target ring network cabinet, under the blowing conditions of the same wind force, the dust content of the flowing air corresponding to different preset dust coverage on the installation panel (it should be noted that the preset dust coverage and the corresponding flowing air dust content are both range values), and the preset threshold value means that when the dust coverage on the surface of the installation panel is greater than a certain value, it means that the electrical components on the installation panel will not be able to perform normal heat dissipation due to the excessive dust coverage. Generally speaking, the preset threshold value is obtained by technicians in this field after multiple tests;

[0123] When the abnormal installation panel is purged with strong wind through the heat dissipation fan, the main ventilation duct and the auxiliary ventilation duct corresponding to the abnormal installation panel, the dust content measuring element arranged near the heat dissipation air outlet in the target ring network cabinet can directly measure the air containing the dust of the abnormal installation panel;

[0124] It can be understood that, since only the auxiliary ventilation duct corresponding to the abnormal installation panel can discharge air, the air in the target ring network cabinet at this time will only contain dust blown out from the abnormal installation panel, and then the dust content of the flowing air measured by the dust content measuring element corresponds to the dust coverage of the abnormal installation panel. After the dust content of the flowing air in the target ring network cabinet at this time is determined by the dust content measuring element in the background processing cloud, the background processing cloud retrieves the preset dust coverage comparison table, and searches the preset dust coverage corresponding to the dust content of the flowing air in the target ring network cabinet in the preset dust coverage comparison table, and determines whether the preset dust coverage found is greater than the preset threshold value. If it is determined that the preset dust coverage found is greater than the preset threshold value, the panel surface cleaning information is generated according to the number of the abnormal installation panel, and sent to the ring network cabinet manager terminal, so that the ring network cabinet manager can dispatch dust cleaning personnel as soon as possible to fully clean the abnormal installation panel;

[0125] It should be noted that although the background processing cloud determines that the overall thermal anomaly of the abnormal installation panel may be related to the excessive dust coverage on its surface, it may also be a situation where there is excessive dust coverage and a series fault. Therefore, after cleaning the dust on the abnormal installation panel, the background processing cloud continues to observe whether the abnormal installation panel still has an overall thermal anomaly. If not, it means that the cause of the thermal anomaly of the abnormal installation panel has been resolved. If it still exists, it means that the abnormal installation panel still has a series fault problem. At this time, the background processing cloud should promptly provide feedback to the target ring network cabinet manager.

[0126] Through the above technical solution, when remotely monitoring the operation of the ring network cabinet, if it is found that the installation panel in the ring network cabinet is overheated as a whole, it can be intelligently judged whether this thermal anomaly is mainly caused by excessive accumulation of dust on the surface. If it is confirmed that it is caused by dust accumulation, only cleaning personnel need to be dispatched to clean the ring network cabinet, and there is no need to use professional maintenance personnel. This technical means can avoid unnecessary dispatch of professionals due to misjudgment of the overall thermal anomaly of the installation panel as a series fault, thereby effectively reducing the maintenance cost of the ring network cabinet.
