Warm congratulations on the successful opening of the 2012 Sichuan Smart Grid and Power System Solutions Exhibition!

In various (a) power systems ranging from power generation, transmission, and power supply to "wired" connections at the end of power consumption, regardless of the size of the power grid, power supply mode, and voltage level (national grid, local independent small power grids, aircraft, trains, warships, aerospace Devices, space stations, and automobiles are each of the same type (a) of power systems), including smart grids, which cannot avoid the international problem of "overheating of electrical contacts".

After more than 40 years of continuous exploration, repeated testing and continuous improvement in production practice, "Research on non-heated electrical contacts, special fasteners for non-heated electrical contacts" Chuanke Jianzi [2011] No. 018, National Science and Technology Achievements The scientific and technological achievements of No. 9512011Y0026 on the Internet have overcome this international problem in one fell swoop, and are a good way to treat the "cancer" of "electric contact overheating" accidents in various (a) power systems.

In the last exhibition, the trademark "Renyi" was registered, and the scientific and technological achievements: the theory and technology of "not hot electrical contacts"; the international invention patent: "the method to eliminate the overheating of electrical contacts" PCT/CN2010/079856; practical The new patented technology is developed and produced as a whole, and has been promoted in many provincial and municipal power companies and some power customers across the country. The electrical equipment and patented products that have been used for many years are displayed. Participants were very interested in another set of theories, concepts, and technologies of "overheating electrical contacts" that were different from the same history, tradition, and habits, especially the one-time and complete elimination of electrical contact overheating accidents. The participating experts and scholars were particularly interested Appreciation from people of insight who have on-site practical experience and strive to eliminate the problem of overheating of electrical contacts. The Western Power Grid, Sichuan Power, National Grid, Central China Power News, and the internal network of the power system have all reported. The theory, concept and technology of "not hot electrical contacts", including the process of eliminating overheating of electrical contacts by oxidation and corrosion. A large number of experts, scholars, maintenance and emergency repair engineers and technicians related to electrical contacts (joints) pay attention to this Career, the exhibition has received certain results.

However, the theory and concept of "not too hot electrical contacts" are just different from the historical, traditional, and habitual mistakes of "electric contacts overheating". It is also a rebellion against the traditional and habitual "trends", especially now in national standards and industry guidelines. The textbooks for colleges and secondary schools, and the national special operating personnel safety technical training and assessment textbook "Electrical Work Industry" are compiled based on the theory and concept of "electrical contact overheating", and oxidation and corrosion are the main directions of electrical contact overheating. . Focusing on prevention, infrared temperature measurement, remedial measures, and repairing accidents are not a cure for the symptoms, such as the "Yaoshun" water treatment method to solve the problem of overheating electrical contacts, and constantly repeat past mistakes. After being unable to eliminate and cure this cancer, the final analysis and treatment of accidents caused by overheating of such electrical contacts are all summed up as "equipment accidents". In the end, it is not the power supply department that is in the dark. Later, it turned back and determined that the weak electrical contact was an important part of overheating, and the "surface phenomenon" of oxidation and corrosion of the contact surface after overheating was identified as the main reason. In addition, the non-professional and inexperienced: "insulation aging, "Excessive load and short circuit cause electrical fire" report, and conduct electrical fire drills. The "grounding and ignition" of the car repair jargon circuit is reported as "automobile spontaneous combustion" and so on, which further paralyzes us. Even aircraft circuit failures, crashes and train rear-end collisions are commonplace. This is the most important matter related to the life and property safety of each of our citizens. How big accidents and disasters will cause us to awaken. When the people's government that considers serving the people as its purpose can pay attention to this matter (including government officials) , The safety of civil servants in relevant functional departments) is the real thing for the people?

Taking advantage of the 2012 Sichuan Smart Grid and Power System Solutions Exhibition, I will use decades of scientific and technological achievements to solve "electrical contact overheating" solutions, hoping to use the scientific and technological achievements of "not hot electrical contacts", from education Before training, design and manufacturing, installation and commissioning, the newly energized power system will be made into an “overheating” type at one time, and the old system with overheated electrical contacts will be gradually transformed into The "overheating" power system has entered a new era of overheating electrical contacts as soon as possible. In fact, the theory and concept of thermal electrical contacts are revolutionary to history and tradition, while technically, we take the road of "improvement", and basically do not change the original system (such as replacing a special tight Firmware”) is very convenient to solve overheating accidents.

It is hoped that the leaders and experts of the organizers and related departments of this exhibition will pay attention to the promotion of the scientific and technological achievements of the "not hot electrical contacts", and build the "not hot electrical contacts" at one time from the research, design, manufacturing, installation, and power on of electrical equipment. "The power grid took the lead in eliminating electrical contact overheating accidents in Sichuan, and has made great achievements in safe production, energy saving and consumption reduction, and reliable power supply to ensure people's lives and property are protected from loss.
