Description

Technical Field

[0001] The present invention relates to the technical field of power monitoring, and particularly to an abnormal monitoring system for high-temperature resistant gold-copper alloy cables based on big data analysis. Background Art

[0002] In fields such as power, machinery, electronics, transportation, and energy, cables, as important transmission media, their performance directly affects the stability and safety of the entire system. With the progress of technology and the improvement of industrial requirements, traditional cable materials have become difficult to meet the usage requirements in some special environments (such as high temperature, corrosion, etc.). Therefore, the research and development of cable materials with higher performance has become an important topic in the industry. Among them, high-temperature resistant gold-copper alloy cables have received extensive attention and applications due to their excellent electrical conductivity, high-temperature resistance, corrosion resistance, etc.

[0003] A high-temperature resistant gold-copper alloy cable is a cable made of gold-copper alloy as the conductor material and processed through a special manufacturing process. This cable not only has the function of transmitting electrical energy like traditional cables, but also can maintain stable performance in high-temperature environments. The gold-copper alloy cable inherits the high electrical conductivity of gold, making it have lower resistance and energy loss when transmitting electrical energy. This is of great significance for improving power transmission efficiency and reducing energy consumption. By adding specific alloy elements (such as chromium, cobalt, etc.), the gold-copper alloy cable can maintain stable performance in high-temperature environments and is not easily softened or deformed. This enables it to still maintain good transmission performance in high-temperature working environments. The gold-copper alloy cable has good corrosion resistance and can resist the erosion of various chemical substances, extending its service life.

[0004] In practical applications, cables may have abnormalities for various reasons, such as overheating, aging, damage, etc. If these abnormalities are not dealt with in a timely manner, they may lead to cable failures or even accidents. Existing cable abnormal monitoring systems do not comprehensively analyze cable abnormalities in multiple dimensions, resulting in error misjudgments, leading to an increase in sudden failures and maintenance costs.
