Combining the "four basic principles" theory of eliminating electrical contact overheating and the "six requirements" technology for overheating electrical contacts, it is "tailor-made" for the electrical connection of "detachable electrical contacts" in various (a) power systems However, it is very convenient to replace the original "standard bolts" with the special fasteners for thermal electrical contacts under the condition that the hole diameter and hole distance are unchanged according to the original national standard GBJ149-90.

All electrical equipment in the power system, such as transformers, circuit breakers, isolating switches, transformers, wall conduits, bus bars, cables, etc., electrical equipment rooms and the "electric contacts" (terminals, terminals, Electrical contacts, joints...) are in accordance with the requirements of GB5780-86, 5790-86 and GB6170-86 in National Standard 149 "Hexagon Bolts and Hex Nuts". The connection method of two flat washers and spring washers is inherently flawed. However, the method of measuring torque value and measuring contact resistance is not scientific, and overheating accidents occur when the running time is long. This type of "electric contact overheating" accidents often cause electrical fires, equipment damage, large-scale power outages, and even more than one or two falls in the sky due to such accidents. Therefore, people mistakenly believe that the weakest and most accident-prone place in the circuit is the electrical contact (electrical connection). In the end, many people think that "the electrical contacts are overheated" is almost right. The temperature of the electrical contact should be higher than the temperature of the conductor (line). There are even different degrees of errors in teaching materials, instruction books, and technical training assessment books for special industries such as colleges and universities, technical secondary schools, and electrical work. "Overheating of electrical contacts" has become a "cancer" in the power system. 'The old problem'.

I am a senior technician who has been engaged in substation maintenance for more than 40 years in the electric power industry. In the hundreds of times of handling and solving "electrical contact overheating" faults and accidents, I have gone through many years of detours in accordance with the original industry standards and regulations. Only after hitting the south wall did the "reverse thinking" slowly figure out a theory based on the "four basic principles" for solving overheating of electrical contacts, and the "six requirements for electrical contacts that are not too hot" (technology) as a dedication to the motherland The 60th birthday gift was reported to the State Council, the National Development and Reform Commission, the State Administration of Security, the Ministry of Construction, the State Power Corporation and other ministries and commissions, and contacted with the National Standard 149, the industry guide and other departments to put forward their own theories and opinions. "Not hot electrical contacts". China; China Renyi Electric. China; Renyi. China, have all made Chinese domain names. "But hot electrical contacts" are their own "intellectual property rights" (so far, many conservative people who are afraid of mentioning the "electric contact revolution" do not accept it). The patented technology (product) 200920080297.1 is based on the theory of "overheating electrical contacts", based on the six requirements (techniques) for overheating electrical contacts, and is specifically aimed at historical and traditional habitual "electrical contact overheating" faults , Accidents, in all kinds of power systems, thoroughly and one-time to solve the "old problem" problem, a cure for cancer. This series of patented products are widely used in the manufacture, installation, use and maintenance of various electrical equipment. Used to replace the original unreasonable standard bolts. At present, the theory and technology of "not hot electrical contacts" and the patented products based on it have been widely used in many power departments across the country, and have achieved good safety, economic, and social benefits.

Intent of cooperation: domestic first, then abroad; the principle of state-owned enterprises first, collective and individual.

All transfers, partial regional transfers, and technology shares can be considered.
