Description

Technical Field

[0001] The invention relates to the technical field of cable plugging, and in particular to a high-current busbar plugging device and a jumper method for a mobile energy storage electrical box. Background Art

[0002] The plugging of high-current busbars in mobile energy storage electrical boxes is an important part of ensuring the safe and reliable operation of power equipment. This plugging usually involves the access of high-voltage electrical equipment, especially during the busbar jumper work process during equipment maintenance, new construction or expansion of line intervals. In order to ensure that other running equipment does not lose power, it is necessary to connect and fix the high-current busbars of different parts to the busbar connection points in a live state to ensure that the jumper wires are firmly connected and in good contact. Special attention should be paid to safety and standardized operation.

[0003] However, the existing technology lacks a comprehensive assessment of power supply safety when performing busbar bridging, which can easily lead to connections that do not meet safety standards, thereby causing power failures or equipment damage. In addition, traditional methods usually rely on static data collection and personnel experience, lack real-time monitoring and abnormality analysis, and the decision-making is not scientific or objective, resulting in failure to timely discover potential faults or abnormalities, thereby increasing the risk of bridging;

[0004] In addition, the existing technology fails to fully consider the impact of changes in construction personnel, tools and environment on the bridging effect, which sometimes leads to unforeseen construction delays or cost increases. It is unable to comprehensively consider multiple factors such as bridging time, bridging cost and power supply safety, resulting in the selected unused busbar contacts may not have the best availability. There is a lack of dynamic monitoring and verification of the completed busbar contacts, and the bridging effect and power supply stability cannot be confirmed in time. Summary of the invention

[0037] Furthermore, the evaluation calculation formula uses time consumption and cost as denominators to reflect the negative impact of such parameters on the availability of the docking point. Time consumption and cost are inversely proportional to the overall availability score. The positive impact on availability is expressed by multiplying user demand, cross-connection capability and security scores. The availability of the docking point is corrected by calculating the average score of the abnormal factor to calculate the availability score U i Used to sort the unused bus contacts.

[0064] Example 2

[0065] In other aspects, this embodiment also provides a method for bridging high-current busbars of a mobile energy storage electrical box, such as Figure 2 As shown, the following steps are included:

[0066] Step 1: Monitor several used bus contacts and unused bus contacts, collect relevant image data, use image processing technology to identify the connection status of the bus contacts, and collect power supply data including current, voltage and load;

[0067] Step 2: Compare the collected image data and power supply data with the preset standard power supply indicators and contact status.

[0069] Step 4: Based on the power supply demand input by the user, the bridging capacity score data and the current abnormal factor set, the bridging time, bridging cost and power supply safety of the bridging scheme are analyzed to evaluate the availability of each unused busbar connection point;

[0070] Step 5: Obtain several unused busbar points for comprehensive availability analysis to assess whether they meet power supply requirements and safety standards.

[0073] Step 8: Within the preset period, determine whether the power supply status after cross-connection is stable through regular monitoring and data verification. If the verification passes, restore the default collection and verification frequency of the bus. If the verification fails, trigger the alarm mechanism in time and isolate the power supply of the bus contact.

[0074] Compared with the prior art, this embodiment ensures the safety of each bus interface through real-time monitoring, data collection and abnormal analysis, significantly reduces the risk of power failure and equipment damage, improves the stability of the power supply system, and provides data-driven decision support by combining user power supply demand, cross-connection capacity score and comprehensive evaluation of abnormal factors. The decision-making process is more objective and scientific, and the wrong choice caused by human factors is reduced.

[0075] After the jumper is connected, the frequency of data acquisition and verification of the busbar is increased, and dynamic monitoring is performed to timely discover potential problems and isolate the power supply when necessary to effectively protect the system safety. The jumper time, jumper cost and power supply safety are comprehensively considered, and the availability of unused busbar interfaces is analyzed and sorted to optimize resource allocation and select the most suitable interface for jumper connection, thereby improving jumper efficiency and reducing costs.

[0076] Taking into account the variables of cross-connection capacity, adaptive adjustments can be made through flexible cross-connection capacity scoring to adapt to different construction conditions and needs, ensure the execution effect of the cross-connection, systematize various data and scores, so that managers can understand the status and risks of each interface at a glance, improve management efficiency, and facilitate subsequent maintenance and decision-making.

[0077] Example 3

[0078] In this embodiment, a calculation formula for evaluating the availability of each unused busbar connection point is provided, which is specifically:

[0079] Where U i Represents the final availability score. The higher the value, the more available the busbar joint is. i Represents the expected spanning time. The smaller the span, the higher the availability score. It is used in the denominator to penalize long spans. i Represents the estimated cross-connection cost. The higher the cost, the lower the availability score. i represents the power supply safety score, which measures the safety of the power supply of the busbar junction in the current state. The higher the score, the safer the power supply. R represents the power supply demand score input by the user, which reflects the power supply required by the equipment at the power connection point. The higher the score, the stronger the demand. K represents the bridging capacity score, which represents the comprehensive capacity coefficient of the construction personnel, tools and environment. The higher the score, the smoother the bridging process can be guaranteed. It represents the impact score of the jth abnormal factor, which indicates the potential negative impact of each abnormal factor on the availability of the connection point, ranging from 0 no impact to 1 great impact. A j represents the number of abnormal factors, which is used to calculate the average impact of abnormal factors on availability. N represents the number of abnormal factors, that is, the total number of different abnormal factors identified during abnormal analysis.

[0080] The evaluation calculation formula uses time and cost as the denominator to reflect the negative impact of such parameters on the availability of the connection point. Time and cost are inversely proportional to the overall availability score. The positive impact on availability is expressed by multiplying user demand, cross-connection capability and security score. All three need to be within a suitable range to improve the availability of the connection point. By calculating the average score of the abnormal factors, the availability of the connection point is corrected to ensure that the availability score of the connection point is appropriately reduced when there are multiple abnormal factors. The calculated availability score U i It is used to sort the unused busbar points and recommend the best cross-connection solution.

[0081] In summary, the present invention can timely discover potential abnormal situations by real-time collection and analysis of image data and power supply data of used bus contacts and unused bus interfaces, which not only improves safety, but also reduces human errors and ensures stable power supply. By analyzing the power supply demand and bridging capacity scoring data input by the user, the present invention provides users with availability analysis and sorting based on multiple factors such as bridging time, cost and safety, and provides a data-driven decision-making method to select appropriate bus interfaces faster and more accurately, optimize the construction process, and reasonably allocate resources, improve construction efficiency and reduce bridging costs by scoring construction personnel, tools and environmental data.

[0082] After completing the cross-connection, the system will dynamically adjust the data collection and verification frequency according to the verification results. This feedback mechanism can timely reflect the working status of the busbar, ensure the safety of power supply, and quickly take isolation measures when abnormalities occur. The abnormal alarm and power supply isolation mechanism can minimize power supply interruptions caused by abnormalities and improve the reliability and availability of the system.

[0083] Improve power supply safety, ensure the safety and stability of the entire power supply system through timely response to abnormal situations and dynamic adjustment of collection frequency, reduce manpower and time costs, reduce unnecessary human resource consumption with intelligent recommendation and analysis algorithms, shorten bridging time, and improve construction efficiency. Through accurate assessment of power supply demand and construction capacity, the bridging process is optimized to make the construction plan more scientific and reasonable. Continuous data verification and monitoring improve the reliability and operating efficiency of the device, and reduce the risk of unexpected power outages and equipment damage.

A method for bridging a high-current busbar of a mobile energy storage electrical box, the method being an implementation method of a high-current busbar plug-in device of a mobile energy storage electrical box based on any one of claims 1-5, characterized in that: The following steps are involved: Step 1: Monitor several used bus contacts and unused bus contacts, collect relevant image data, use image processing technology to identify the connection status of the bus contacts, and collect power supply data including current, voltage and load; Step 2: Compare the collected image data and power supply data with the preset standard power supply indicators and contact status. Based on the results of the data comparison, perform an abnormal analysis, identify the abnormal factors and output them as an abnormal factor set. For each parameter in the abnormal factor set, determine whether it exceeds the preset standard threshold. If so, trigger an alarm mechanism. Step 3: Collect the user's power supply needs, including the power supply setting parameters of the equipment at the power connection point and the power supply operation parameters and cross-connection capacity scoring data of the current power grid; Step 4: Based on the power supply demand input by the user, the bridging capacity score data and the current abnormal factor set, the bridging time, bridging cost and power supply safety of the bridging scheme are analyzed to evaluate the availability of each unused busbar connection point; Step 5: Obtain several unused busbar points for comprehensive availability analysis to assess whether they meet power supply requirements and safety standards. Based on the assessment results, sort the unused busbar points by availability, generate a recommendation list, and display it to the user. Step 6: Use the unused bus contacts recommended by the user to complete the jumper connection and connect to the target device; Step 7: After the cross connection is completed, enter the preset cycle and increase the acquisition and verification frequency of the busbar contact according to the set frequency level; Step 8: Within the preset period, determine whether the power supply status after cross-connection is stable through regular monitoring and data verification. If the verification passes, restore the default collection and verification frequency of the bus. If the verification fails, trigger the alarm mechanism in time and isolate the power supply of the bus contact.
