Description

Technical Field

[0001] The present invention relates to the field of automatic control technology, and in particular to an automatic control system for power distribution. Background Art

[0002] In modern industrial and power systems, the stability and safety of electrical components are crucial to the operation of the entire system. Electrical components, such as transformers, motors, and power distribution equipment, usually operate in high-load and complex working environments. Due to long-term operation, load fluctuations, and changes in environmental factors, these devices may experience overheating, overloading, corrosion, and other faults, resulting in equipment performance degradation, or even equipment damage or fire and other safety accidents. Therefore, how to monitor the working status of electrical components in real time, discover potential failure risks in a timely manner, and take effective preventive measures has become an important topic in power management and equipment maintenance. Traditional power system maintenance relies on regular manual inspections and equipment maintenance, however, this approach has significant limitations. First, the frequency of manual inspections is not high, there is a certain lag, and it is easy to miss some hidden dangers or minor faults; second, the operating environment of electrical components is usually complex and scattered, and manual positioning and inspection are difficult, which is easy to waste time and resources. In addition, with the increase in the number of equipment, the cost of manual inspections and maintenance is also rising, and the long repair cycle when equipment failure occurs often leads to production line shutdowns, economic losses, and even serious safety impacts. In order to solve these problems, intelligent electrical component monitoring systems have emerged. By installing sensors and monitoring devices, the working status data of electrical components can be obtained in real time, and by comparing the data with the preset standards through data analysis, potential abnormalities can be discovered in time and early warning signals can be issued in advance. In this way, remote monitoring and automatic diagnosis of equipment can be achieved, the frequency and cost of manual inspections can be significantly reduced, and the efficiency and safety of equipment can be improved. However, after detecting an abnormality, how to respond quickly and effectively to ensure that the equipment can be automatically repaired or adjusted, and provide accurate positioning and manual intervention when necessary, is also one of the challenges faced by intelligent electrical appliance monitoring systems. In order to improve the fault response speed, the system needs to be able to automatically adjust parameters such as current and fan speed to reduce damage and extend the life of the equipment. If the automatic repair fails, it is necessary to accurately locate the location of the problem equipment to help the manual re-inspection module quickly arrive at the site for further inspection and repair. Therefore, an automatic control system for power distribution is proposed. Summary of the invention

[0038] 1. The electrical component monitoring and early warning module continuously monitors temperature, humidity, current, etc., and checks for potential faults, and handles them in advance to avoid equipment failures. The red display helps users quickly locate the problem equipment. When the warning characteristic value is lower than the threshold, the system will send a control signal to adjust the power distribution control module to achieve automatic adjustment or protection of the equipment. If the problem cannot be solved automatically, the manual re-inspection module will trigger manual intervention.

[0039] 2. The power distribution control module can adjust the operating status of the equipment, reduce equipment loss, and avoid equipment failure due to overload and other reasons. In addition to current compensation, the power distribution control module is also connected to the cooling system. After receiving the early warning signal, the fan speed is adjusted according to the early warning characteristic value to maintain the normal temperature range of the equipment. The fan speed is combined with parameters such as the temperature and humidity of the electrical components to ensure that the equipment can operate in the best working state.

After receiving the first warning signal, the count number is set to be 1, and then the count number is determined to be greater than 1.
