Description

Technical Field

[0001] The invention relates to the technical field of insulator manufacturing, and in particular to an insulator production system and a production method. Background Art

[0002] At present, the power industry is in a stage of vigorous development. With the continuous growth of economic and social demand for electricity and the continuous expansion of the scale of power grid construction, the requirements for the stability and safety of the power transmission system are also increasing. Insulators, as a key component in the power transmission system, play an indispensable role in ensuring the safe transmission of electricity. Specifically, they can achieve electrical insulation and provide reliable mechanical support for the line. Insulators are common components in transformers and motors. When in use, the copper rod is passed through the upper part of the insulator axis and fixed to the cable or busbar through screws to isolate the steel structure, increase the creepage distance, and improve the safety performance of operation. At present, the insulators used in transformers are generally made of ceramic as the material. The material will age and crack in the wind and sun, affecting the electrical performance and causing failures. Based on the above aspects, the system improves the material's aging resistance, voltage rating, corrosion resistance and impact resistance; achieving stability and safety of the motor system.

[0003] There are many problems with the traditional insulator production method. From the perspective of the production process, the connection mechanism between the various links is not perfect. For example, there may be problems such as untimely material transportation and inconsistent connection rhythm between the raw material processing link and the molding link, which will cause efficiency loss in the entire production process and cannot meet the needs of modern large-scale and high-efficiency production. In terms of quality control, the quality monitoring and control methods under the traditional production model are relatively backward, making it difficult to achieve accurate and real-time quality control of the entire production process. Due to the lack of highly sensitive testing equipment and intelligent quality monitoring systems, key factors affecting quality such as raw material mixing ratio deviation, dimensional accuracy error in the molding process, and temperature fluctuation in the firing link cannot be discovered and effectively adjusted in a timely and accurate manner, which undoubtedly increases the risk of producing unqualified products. In addition, the traditional insulator production method has serious deficiencies in data utilization. A large amount of data generated during the production process, such as equipment operating parameters, process execution status, quality inspection results, etc., has not been deeply mined and integrated through effective data analysis methods, resulting in the inability of these data to fully realize their potential value. It is also difficult to achieve accurate optimization of the production process based on data feedback, which restricts the further improvement of the quality and efficiency of insulator production.
